Description

An anti-infection medical transfer bed

technical field

The utility model relates to a transportation tool technology for loading and unloading patients, in particular to an infection-proof medical transfer bed.

Background technique

At present, the medical transfer bed is to move and transfer patients with inconvenience before and after surgery, move the patient from the hospital bed to the transfer bed, and then from the transfer bed to the operating table or equipment that needs examination/treatment, or reverse transfer.

The medical transfer bed sold or used on the market is mainly composed of two parts, one part is the body used for moving, and the other part is the moving bed plate mechanism used for laterally moving and transporting patients; The medical patient transport vehicle includes a body and a conveying bed table top (moving bed plate mechanism). Under the action of the motor, it translates laterally forward and backward. Another example is the "medical patient transfer cart" disclosed in Chinese Patent No. 200610052776.3. The moving bed plate mechanism adopts a double-layer combined structure of an upper moving frame/upper moving cloth and a lower moving frame/lower moving cloth, and specifically includes a roll cloth shaft frame, Reeling shaft, end joint seat, clutch gear, upper moving frame/upper moving cloth, lower moving frame/lower moving cloth and other components.

However, these medical transfer beds have the following defects:

1. Hygiene issues

The transmission belt or the upper and lower moving cloths are in direct contact with the patient's body, and the cloth surface is easily dirty, including blood stains, human exudates, therapeutic drug exudates and other stains. It is difficult to clean and replace the conveyor cloth with the closed ring-shaped conveyor cloth when it is hidden in the machine. The disassembly and assembly work of replacing the conveyor cloth is no less than that of assembling a new machine. Therefore, the problem of dirty cloth surface cannot be solved. . Every time a patient is transferred, the method of replacing the upper and lower moving cloths can solve the problem of cross-infection, but it is not realistic. After all, after the medical equipment is disassembled, it takes a long time for professionals to re-adjust the equipment, so this method is not optimal. solution. In order to avoid cross-infection between patients when different patients use the same transfer vehicle, it is necessary to design a transfer bed that can automatically lay isolation pads.

2. Structural problems

The above-mentioned transmission belt (Chinese patent 98205338.X) or the upper moving cloth (China patent 200610052776.3) are driven by the rubber roller to rotate, thereby driving the transmission belt or the upper moving cloth sleeved on the rubber roller to move laterally back and forth to get closer or farther away. Operating table/hospital bed, because the transmission of the cloth surface requires a certain tension, the tension of the cloth surface needs to be adjusted after a long time. If the cloth surface is stretched to a certain extent, it must be replaced. The cloth surface of this structure is easy to move left and right, and needs to be adjusted; in addition, the setting of the rubber roller will also cause many problems. The gap between the roller 15 and the end fitting base 16 is easy to wind the clothes into the rubber roller, and it is also possible that the hair is caught in the process of transferring the patient; and the rubber roller is also aging, and it is necessary to replace the rubber roller and re-adjust the running state of the equipment. And other issues.

For example, the transmission mechanism of Chinese Patent No. 200610052776.3 adopts a clutch transmission. The clutch adopts a mechanical control structure in which two clutch gears are attached and separated. The disadvantage is that the design structure is complex and prone to failure; especially the clutch part, when it needs to be combined, when the two When the two teeth of a clutch gear are not coordinated, the combination will not be smooth, and when separation is required, when the two teeth are meshed, there will be separation resistance, resulting in a large difference in movement and positioning, and the patient transfer work cannot be completed.

In addition, the conveying belt or the upper and lower moving cloths are all annular closed conveying cloths, which are in direct contact with the patient's body and are the main components used to directly transport the patient; due to the needs of medical hygiene, the conveying belt or the moving up and down Disinfection of the cloth surface can easily lead to the cracking of the cloth surface interface, and the structural strength is not enough.

3. Security issues

For example, the medical patient transfer vehicle in Chinese Patent No. 200610052776.3 drives the rubber roller to rotate through the driving mechanism, thereby driving the transmission cloth sleeved on the rubber roller to move back and forth, which may cause misoperation to cause the patient to collide with the end joint seat 16, or even cross the Consequences of the end fitting body 16 falling to the bed frame of the transfer bed. Under normal conditions, when a person is lying on the conveying cloth, the driving mechanism stops driving the rubber roller to rotate, and the conveying cloth is in a static state, and only needs to move the moving plate up and down to complete the transfer to the desired position. If the patient is already on the transfer bed and presses the button inserted into the bed by mistake, the patient will hit the end joint base 16 or even fall across the end joint base 16 to the transport bed frame, resulting in a medical accident.

Preferably, the locking bar driving mechanism is selected from one or a combination of two or more of a motor, a ratchet, a braking mechanism, and an electromagnetic device.

Compared with the prior art, the beneficial effects of the present utility model are:

(1) One of the cores of the present utility model is that by setting the isolation pad laying mechanism, when the moving bed plate mechanism of the transfer bed extends the up and down moving plate in connection with the patient, the upper isolation pad fixed on the locking strip will follow the movement of the up and down moving plate. When the moving bed plate mechanism needs to retract the up and down moving plate after receiving the patient, the locking strip is released and locked, and the upper isolation pad It moves synchronously with the upper and lower moving plates and the upper moving cloth, and is always placed between the patient and the upper moving cloth, so that the blood stains or therapeutic drugs on the patient's body will not stain the upper moving cloth due to the isolation of the upper moving cloth, and the upper moving cloth will not be dirty. Contaminated by picking up patients, reducing the risk of cross-infection between patients. In addition, when the moving bed plate mechanism of the transfer bed is picking up the patient and extending the upper and lower moving plates, the lower isolation pad fixed on the transfer side of the carriage is simultaneously drawn into the space between the lower moving cloth and the operating bed with the extension of the upper and lower moving plates. During the operation, the lower moving cloth will not be polluted by the blood stains or therapeutic drugs remaining on the operating bed; when the moving bed plate mechanism needs to retract the upper and lower moving plates when receiving the patient, the lower isolation pad will remain on the operating bed, so that the remaining blood stains or treatment on the operating bed will not be contaminated. Because of the isolation of the lower isolation pad, the medicine will not contaminate the transfer bed, which ensures the hygienic standard when the operating bed is used for the second time, and reduces the risk of cross-infection between patients.

When the moving bed plate mechanism of the transfer bed is sending the patient to extend the up and down moving plate, the patient and the upper isolation pad move synchronously and laterally with the extension of the up and down moving plate; The upper isolation pad, when the moving bed plate mechanism of the transfer bed retracts the up and down moving plate after sending people, the upper isolation pad remains between the patient and the bed, ensuring the isolation between the patient and the bed and reducing the risk of infection.

In general, the anti-infection medical transfer bed of the present invention is provided with an isolation pad laying mechanism, so that the upper isolation pad can ensure that the upper movable cloth will not be polluted during the process of receiving and sending patients. After the patient is sent back to the hospital bed, the upper isolation pad is kept on the hospital bed simultaneously, which can also achieve hygienic isolation between the patient and the hospital bed. The lower isolation pad can ensure that the lower moving cloth will not be contaminated by blood stains or therapeutic drugs remaining on the operating bed during the process of picking up patients. At the same time, when picking up the patient to the transfer bed, the lower isolation pad will stay on the operating bed synchronously to isolate the source of infection. .

(2) The second core of the present utility model is that the locking bar is longitudinally arranged on the upper moving cloth, and the locking bar is fixed on the upper moving cloth. The cloth moves laterally forward and backward on the upper moving plate; when the moving bed plate mechanism needs to retract the up and down moving plate for receiving patients, and needs to extend the up and down moving plate for sending patients (that is, when the upper moving plate loads the patient), it is driven by the moving bed driving mechanism. , the upper and lower moving plates move laterally, the locking strip drive mechanism drives the locking strip and the upper moving plate to move laterally forward and backward synchronously, and the patient lying on the upper moving plate is relatively stationary with the locking strip. The frictional force generated by the passive rotation of the lower moving plate overcomes the frictional force at the contact surface of the upper and lower moving cloths, so that the upper moving plate, the upper moving cloth and the patient are relatively static, and the lower moving cloth is relatively relative to the lower moving plate and the upper moving plate. Relative movement, but the contact part between the lower moving cloth and the bed surface of the hospital bed is still relatively static, so the resistance is still relatively small, and there is no problem of winding sheets. When the moving bed plate mechanism needs to extend the up and down moving plate for receiving the patient, and when sending the patient needs to retract the up and down moving plate, the locking strip driving mechanism self-locks the locking strip and fixes the locking strip at the initial position. , the upper moving plate and the lower moving plate move laterally forward and backward at the same time (forward lateral movement means that the upper and lower moving plates are gradually inserted between the patient and the bed, and backward lateral movement means that the upper and lower moving plates are gradually withdrawn between the patient and the bed), The lower moving cloth moves relative to the lower moving plate, and the contact portion between the lower moving cloth and the patient bed/operating bed and the bed surface remains relatively static, and the contact surface between the upper moving cloth and the lower moving cloth also remains relatively static, and the upper moving cloth remains relatively static. The contact part between the moving cloth and the patient and the patient also remains relatively static. Therefore, during the overall movement of the up and down moving plate, there is no other relative movement except the relative movement between the moving cloth and the corresponding moving plate. That is to say, There is no sliding friction such as between the moving cloth and the bed surface/patient, so the resistance is very small, and the bed and the patient are relatively stationary with the moving cloth in contact with them, and the sheet can therefore ensure that the moving plate is smoothly inserted under the patient, and The sheets are also not driven, the patient is not pushed, the patient is not pushed or pulled. The entire pick-up process is very smooth, with little friction and resistance.

In general, the utility model replaces the method of driving the rubber roller to rotate the transmission cloth in the prior art by arranging the locking strip and the power mechanism of the locking strip, which simplifies the structure of the moving bed plate mechanism. Problems related to the cots, such as the need to adjust the tension of the cloth surface, the movement of the cloth surface, hair clipping, rolling clothes, the need to replace the cots due to the aging of the cots, the complex transmission of the clutch, the medical accident caused by the fall due to misoperation, etc. At the same time, the utility model picks up the patient more smoothly. Compared with the prior art, the resistance and friction force in the process of picking up the patient is greatly reduced, and the moving plate can be inserted under the patient very smoothly without human intervention; The friction coefficient is required, the moving resistance is smaller, and the power consumption is smaller. The drive motor with lower power can be used, and the transmission is simpler, which is more conducive to increasing the load of the vehicle and reducing the production cost.

(3) The upper moving cloth and/or the lower moving cloth are designed in the form of openings, which can meet the needs of disassembly and replacement, achieve the purpose of preventing infection, and will not affect the strength after disinfection.

The vehicle body 200 is composed of a base 21 , a frame 22 , a lift bracket 23 connected between the base and the frame, and the like. A universal caster 24 is installed below the base, and a brake pedal 25 is also provided on the guide caster and the universal caster on the rear side of the vehicle body, so that the operator can easily brake the transfer vehicle. The lifting bracket 23 is driven by a lifting motor 26 installed at the bottom of the vehicle frame and a telescopic rod 27 connected between the lifting motor and the lifting bracket to complete the lifting action. The left and right ends of the frame are end frames, and the front and rear sides of the frame are provided with reversible guardrails (not shown in the figure). The rear side of the frame also leads out a wire, and the end of the wire is connected with a hand-held controller (not shown in the figure), which is used to control the action of each motor on the medical patient transfer car.

The anti-infection medical transfer bed has two main functions for picking up patients, namely picking up patients and sending patients. Picking up patients refers to transferring patients from the hospital bed to the medical transfer bed; sending patients refers to transferring patients from the medical transfer bed to the medical transfer bed. In the hospital bed; whether it is to pick up or send a patient, it needs to go through two actions, one is to extend the upper and lower moving plates, and the other is to retract the upper and lower moving plates.

One of the cores of the utility model is that by setting the isolation pad laying mechanism, when the moving bed plate mechanism of the transfer bed extends the upper and lower moving plates to receive the patient, the upper isolation pads fixed on the locking strips follow the extension of the upper and lower moving plates. At the same time, it is drawn between the patient and the upper moving cloth, thereby isolating the patient from the upper moving cloth; when the moving bed board mechanism needs to retract the upper and lower moving plates when receiving the patient, the locking strip is released and locked, and the upper isolation pad moves up and down with it. The board and the upper moving cloth move synchronously, and are always placed between the patient and the upper moving cloth, so that the blood stains or therapeutic drugs on the patient's body will not contaminate the upper moving cloth due to the isolation of the upper isolation pad, and the upper moving cloth will not be connected to the patient. and contamination, reducing the risk of cross-infection between patients. In addition, when the moving bed plate mechanism of the transfer bed is picking up the patient and extending the upper and lower moving plates, the lower isolation pad fixed on the transfer side of the carriage is simultaneously drawn into the space between the lower moving cloth and the operating bed with the extension of the upper and lower moving plates. During the operation, the lower moving cloth will not be polluted by the blood stains or therapeutic drugs remaining on the operating bed; when the moving bed plate mechanism needs to retract the upper and lower moving plates when receiving the patient, the lower isolation pad will remain on the operating bed, so that the remaining blood stains or treatment on the operating bed will not be contaminated. Because of the isolation of the lower isolation pad, the medicine will not contaminate the transfer bed, which ensures the hygienic standard when the operating bed is used for the second time, and reduces the risk of cross-infection between patients.

When the moving bed plate mechanism of the transfer bed is sending the patient to extend the up and down moving plate, the patient and the upper isolation pad move synchronously and laterally with the extension of the up and down moving plate; The upper isolation pad, when the moving bed plate mechanism of the transfer bed retracts the up and down moving plate after sending people, the upper isolation pad remains between the patient and the bed, ensuring the isolation between the patient and the bed and reducing the risk of infection.

In general, the anti-infection medical transfer bed of the present invention is provided with an isolation pad laying mechanism, so that the upper isolation pad can ensure that the upper movable cloth will not be polluted during the process of receiving and sending patients. After the patient is sent back to the hospital bed, the upper isolation pad is kept on the hospital bed simultaneously, which can also achieve hygienic isolation between the patient and the hospital bed. The lower isolation pad can ensure that the lower moving cloth will not be contaminated by blood stains or therapeutic drugs remaining on the operating bed during the process of picking up patients. At the same time, when picking up the patient to the transfer bed, the lower isolation pad will stay on the operating bed synchronously to isolate the source of infection. .

In this embodiment, the two ends of the lower moving cloth can be fixed in a variety of ways, and an integral fixing method can be adopted, such as fixing at the bottom of the frame of the vehicle body by using a holding piece, or fixing at the bottom of the frame of the vehicle body by means of riveting. That is, this method is suitable for the conveying cloth in which the lower moving cloth is closed in a ring shape; it can also be fixed in a separate way, that is, two fixing parts are used to correspond to the cloth openings at both ends of the lower moving cloth, which is suitable for the open conveying cloth.

The second core of the utility model is that the locking bar is longitudinally arranged on the upper moving cloth, the locking bar is fixed on the upper moving cloth, and the locking bar driving mechanism drives the locking bar to move laterally, so as to draw the upper moving cloth on the upper moving cloth. The moving plate moves laterally forward and backward; when the moving bed plate mechanism needs to retract the up and down moving plate for receiving patients or extend the up and down moving plate for sending patients (that is, when the upper moving plate loads the patient), the locking strip is released and locked, and the upper moving cloth , The upper moving plate, the lower moving plate and the patient are relatively static, the lower moving cloth moves relative to the lower moving plate and the upper moving cloth, but the part of the lower moving cloth in contact with the hospital bed/operating bed is in contact with the hospital bed/operating bed. The time is still relatively static; therefore, the resistance is still relatively small, and there is no problem of winding sheets. When the moving bed plate mechanism needs to extend the up and down moving plate for receiving the patient or when the patient needs to retract the up and down moving plate, the locking strip driving mechanism self-locks the locking strip and fixes the locking strip at the initial position. , the upper moving plate and the lower moving plate move laterally forward and backward at the same time (forward lateral movement means that the upper and lower moving plates are gradually inserted between the patient and the bed, and backward lateral movement means that the upper and lower moving plates are gradually withdrawn between the patient and the bed), The lower moving cloth moves relative to the lower moving plate, and the contact portion between the lower moving cloth and the patient bed/operating bed and the bed surface remains relatively static, and the contact surface between the upper moving cloth and the lower moving cloth also remains relatively static, and the upper moving cloth remains relatively static. The contact part between the moving cloth and the patient and the patient also remains relatively static. Therefore, during the overall movement of the up and down moving plate, there is no other relative movement except the relative movement between the moving cloth and the corresponding moving plate. That is to say, There is no sliding friction between the moving cloth and the bed surface of the hospital bed, so the resistance is very small, and the bed and the patient are relatively stationary with the moving cloth in contact with them, and the sheet can ensure that the moving plate is smoothly inserted under the patient, and the bed sheet is also Not being driven, the patient is not being pushed, the patient is not being pushed or pulled. The entire pick-up process is very smooth, with very little friction and resistance.

In the present utility model, the main function of the locking bar driving mechanism is to lock the locking bar on the pick-up side of the upper moving cloth or release the locking and locking bar, so that the upper moving cloth moves later. In the process of picking up the patient and needing to extend the up and down moving board or sending the patient back and need to retract the up and down moving board, the locking bar needs to be locked in the initial position Z (the pick-up and drop-off side of the transfer bed). The moving board moves back and forth laterally at the same time (forward lateral movement means that the up and down moving board is gradually inserted between the patient and the bed, and backward lateral movement means that the up and down moving board is gradually withdrawn between the patient and the hospital bed), so as to realize picking up or sending patients. function. In this embodiment, as shown in Fig. 4, Fig. 9, Fig. 17, Fig. 19-21, the locking bar driving mechanism adopts motor self-locking to lock the locking bar.

The design can save the installation positions of the two transmission devices of the locking strip driving mechanism and the moving plate driving mechanism, and is more suitable for the transfer process of the transfer bed.

The working process of the medical transfer bed in the preferred embodiment of the present utility model:

As shown in Figure 26-27, the initial state of the medical transfer bed before picking up the patient is that the moving bed plate mechanism is parked on the frame of the car body, and the right side of the medical transfer bed is an operating bed or a hospital bed; the locking of the moving bed plate mechanism The bar is locked on the pick-up side of the upper moving plate, and the fixing piece is fixed on the frame;

(1) The process of extending the upper and lower moving plates when receiving patients: the locking bar motor of the locking bar driving mechanism is self-locking, the motor does not rotate, the second transmission roller chain is also stationary, and the locking bar is fixed on the The initial position does not move. At this time, the upper moving plate and the lower moving plate are driven by the moving plate drive mechanism to move forward and laterally, the lower moving cloth moves relative to the lower moving plate, and the lower moving cloth is in contact with the hospital bed/operating bed It remains relatively static with the bed surface, and also remains relatively static between the contact surfaces of the upper moving cloth and the lower moving cloth, and also remains relatively static between the upper moving cloth and the contact part of the patient and the patient. During the overall movement of the plate, there is no other relative movement except the relative movement between the moving cloth and the corresponding moving plate. The sliding friction with the upper moving cloth, so the resistance is very small, and the bed sheet or disposable mattress is actually relatively static with the lower moving cloth contact surface, so it can ensure that the moving plate is smoothly inserted under the patient, and the bed sheet or disposable mattress can be smoothly inserted under the patient. The sex mattress will not be driven, and the patient will not be pushed; the patient can be connected to the mobile bed without human intervention;

In addition, when the moving bed plate mechanism of the transfer bed receives the patient and extends the upper and lower moving plates, the upper isolation pad fixed on the locking strip is simultaneously drawn between the patient and the upper moving cloth along with the extension of the upper and lower moving plates. Thereby, the patient is isolated from the upper moving cloth; while the lower isolation pad fixed on the delivery side of the frame is drawn between the lower moving cloth and the operating bed with the extension of the upper and lower moving plates, and the lower moving cloth will not be affected. Bloodstains or contamination of therapeutic drugs remaining on the operating table.

(2) The process of retracting the upper and lower moving plates when receiving the patient: after the upper moving plate loads the patient, the locking bar motor rotates, and through the linkage action of the second link shaft, synchronously drives the second outer sides of the longitudinal two sides of the moving bed plate mechanism When the main sprocket rotates, the locking bar fixed on the second transmission roller chain is pulled and moved relatively, and the locking bar is transferred to the side away from the pick-up side; when the moving bed driving mechanism drives the upper and lower moving plates When the horizontal retraction action is performed backwards, the locking strip moves synchronously with the upper moving plate, and the cloth surface of the upper moving cloth is stationary relative to the upper moving plate; that is, the upper moving cloth, the upper moving plate, the lower moving plate and the patient are relatively static. , the lower moving cloth moves relative to the lower moving plate and the upper moving cloth, but the part of the lower moving cloth in contact with the hospital bed/operating bed is still relatively static;

In addition, when the moving bed plate mechanism needs to retract the up and down moving plate when receiving the patient, the locking strip is released and locked, and the upper isolation pad moves synchronously with the up and down moving plate and the upper moving cloth, and is always placed between the patient and the upper moving cloth, so that Bloodstains or therapeutic drugs on the patient will not stain the upper moving cloth due to the isolation of the upper isolation pad, and the upper moving cloth will not be contaminated by picking up patients, reducing the risk of cross-infection between patients; while the lower isolation pad remains in the operation On the bed, bloodstains or therapeutic drugs remaining on the operating bed will not contaminate the transfer bed due to the isolation of the lower isolation pad, ensuring the hygienic standard of the operating bed when it is used for the second time, and reducing the risk of cross-infection between patients.

(3) The process of extending the upper and lower moving plates when sending the patient: the patient is transferred to the medical transfer bed, that is, the upper moving plate still loads the patient, and the moving bed driving mechanism drives the upper and lower moving plates to extend laterally forward; The locking bar motor still rotates, and the locking bar moves synchronously with the upper moving plate; at this time, the upper moving cloth, the upper moving plate, the lower moving plate and the patient are all relatively static, and the lower moving cloth is relative to the lower moving plate and the upper moving plate. The moving cloth moves relatively, but the part of the lower moving cloth in contact with the hospital bed/operating bed is still relatively static;

In addition, when the moving bed plate mechanism of the transfer bed is sending the patient to extend the up and down moving plate, the patient and the upper isolation pad move synchronously and laterally with the extension of the up and down moving plate.

(4) The process of retracting the upper and lower moving plates when sending the patient: When the patient is sent to the top of the hospital bed/operating table, the locking bar motor of the locking bar driving mechanism is self-locking, the motor does not rotate, and the second transmission roller chain is also stationary Do not move, fix the locking strip at the initial position and do not move. At this time, the upper moving plate and the lower moving plate are driven by the moving plate driving mechanism to move laterally backwards, and the lower moving cloth moves relative to the lower moving plate, while The lower moving cloth and the contact part of the hospital bed/operating bed and the bed surface remain relatively static, and the contact surface between the upper moving cloth and the lower moving cloth also remains relatively static, and the contact part between the upper moving cloth and the patient and the patient also remain relatively static. Remaining relatively still, therefore, during the overall movement of the upper and lower moving plates, there is no other relative movement except the relative movement of the moving cloth and the corresponding moving plate, and a transfer is completed.

In addition, after the patient is sent to the top of the bed, loosen the upper isolation pad fixed on the locking strip. When the moving bed plate mechanism of the transfer bed retracts the upper and lower moving plates after the patient is sent, the upper isolation pad remains between the patient and the bed. It ensures the isolation between the patient and the hospital bed and reduces the risk of infection.

After the above steps (1)-(4), the transfer bed has completed a transfer action and a laying action of the isolation pad at the same time, and the isolation pad between the upper and lower moving plates has been used. The motor drives the narrow strip edge 613 to make the next set of isolation pads in place. Of course, it is also possible to drive the next set of isolation pads into place without using the winding motor. The above two operating states will not affect the normal transfer function of the transfer bed. It is explained that the function of laying isolation pads added by the utility model has an ingenious structure and will not have any influence on the normal transfer of the transfer bed.

Example 2

Compared with Example 1, the difference between the anti-infection medical transfer bed of Example 2 is that the isolation pad is a single-layer structure, that is, one side of the single-layer isolation pad is fixed on the pick-up side of the locking strip or the frame, and the rest of the structure is the same as the embodiment. 1 is the same. This embodiment illustrates that when the isolation pad is a bed sheet, the bed sheet required in different places can be replaced according to actual use needs. Of course, the laying of the isolation pad in this embodiment 2 can also be realized by an automatic unwinding device.

As shown in Figures 26-27, an anti-infection medical transfer bed includes a car body with a lifting mechanism and mounted with universal casters, and a mobile bed plate mechanism for laterally moving and transporting patients; the mobile bed plate mechanism is installed on the car body. The moving bed plate mechanism includes an upper moving plate 1, an upper moving cloth 2, a lower moving plate 3, and a lower moving cloth 4; the lower moving plate is arranged below the upper moving plate, and the upper moving plate and, The lower moving plate moves laterally forward or backward synchronously; the upper moving cloth is wrapped around the outer circumference of the upper moving plate, and the upper moving cloth is longitudinally fixed with a locking strip 5, which is locked on the upper moving cloth. The pick-up side moves with the upper moving cloth after releasing the lock; the lower moving cloth is wrapped around the outer periphery of the lower moving plate, and both ends of the lower moving cloth are fixed on the frame of the vehicle body and are located on the pickup side of the lower moving plate; The anti-infection medical transfer bed also includes an isolation pad laying mechanism, and the isolation pad laying mechanism includes an isolation pad (the isolation pad can be an upper isolation pad 611 or a lower isolation pad 612 ), and the isolation pad is laid on the upper moving cloth and the lower Between the moving cloths, one side of the isolation pad is fixed on the locking strip or the pick-up side of the frame.

Example 3

Compared with the embodiment 1, the medical transfer bed of the embodiment 3 is different in the driving mechanism of the locking bar, and the rest of the structure is the same as that of the embodiment 1. In this embodiment, the locking bar driving mechanism adopts one of the existing locking mechanisms such as a ratchet, a structure similar to a ratchet, a braking mechanism, or an electromagnetic device. When the locking mechanism such as ratchet or electromagnetic device is released (that is, the upper moving plate loads the patient), since the patient is pressed on the upper moving cloth, the friction between the upper moving cloth and the upper moving plate is large enough to overcome the passive movement of the lower moving cloth. The resulting friction causes the upper moving cloth to be relatively stationary with the patient and the upper moving plate.

The working process of the medical transfer bed in the preferred embodiment of the present utility model:

As shown in Figure 26-27, the initial state of the medical transfer bed before picking up the patient is that the moving bed plate mechanism is parked on the frame of the car body, and the right side of the medical transfer bed is an operating bed or a hospital bed; the locking of the moving bed plate mechanism The bar is locked on the pick-up side of the upper moving plate, and the fixing piece is fixed on the frame;

(1) The process of extending the upper and lower moving plates when receiving the patient: the locking strip driving mechanism (such as ratchet or electromagnetic device, etc.) self-locks the locking strip, and fixes the locking strip at the initial position. The upper moving plate and the lower moving plate are driven by the moving plate drive mechanism to move laterally forward, the lower moving cloth moves relative to the lower moving plate, and the contact portion between the lower moving cloth and the hospital bed/operating bed and the bed surface remains relatively static, Moreover, the contact surfaces of the upper moving cloth and the lower moving cloth also remain relatively static, and the contact part between the upper moving cloth and the patient and the patient also remains relatively static. In addition to the relative movement with the corresponding moving board, there is no other relative movement; that is to say, there is no sliding friction between the moving cloth and the operating bed or the bed surface of the hospital bed, and there is no sliding friction between the patient and the upper moving cloth , so the resistance is very small, and the bed sheet or disposable mattress is actually relatively static with the lower moving cloth contact surface, so it can ensure that the moving plate is smoothly inserted under the patient, and the bed sheet or disposable mattress will not be driven, The patient will not be pushed; the patient can be connected to the mobile bed without human intervention;

In addition, when the moving bed plate mechanism of the transfer bed connects the patient and extends the up and down moving plate, the up and down moving plate tops off the connection point on the easy tearing position of the isolation pad, so that the isolation pad is disconnected from the edge of the narrow strip; The upper isolation pad on the strip is simultaneously drawn between the patient and the upper moving cloth with the extension of the upper and lower moving plates, thereby isolating the patient from the upper moving cloth; When the lower moving plate is stretched out, it is simultaneously drawn between the lower moving cloth and the operating bed, and the lower moving cloth will not be contaminated by blood stains or therapeutic drugs remaining on the operating bed.

(2) The process of retracting the upper and lower moving plates when receiving patients: after the upper moving plate loads the patient, the ratchet is released and locked, and the moving bed driving mechanism drives the upper and lower moving plates to retract laterally; Press on the upper moving cloth, the friction force between the upper moving cloth and the upper moving plate is large enough to overcome the friction generated by the passive movement of the lower moving cloth, so that the upper moving cloth and the patient are relatively stationary, and the locking strip is transferred to the side away from the pick-up side. One side; at this time, the upper moving cloth, the upper moving plate, the lower moving plate and the patient are all relatively static, the lower moving cloth moves relative to the lower moving plate and the upper moving cloth, but the lower moving cloth and the hospital bed/operating bed move relatively The contact part is still relatively stationary with the hospital bed/operating bed;

In addition, when the moving bed plate mechanism needs to retract the up and down moving plate when receiving the patient, the locking strip is released and locked, and the upper isolation pad moves synchronously with the up and down moving plate and the upper moving cloth, and is always placed between the patient and the upper moving cloth, so that Bloodstains or therapeutic drugs on the patient will not stain the upper moving cloth due to the isolation of the upper isolation pad, and the upper moving cloth will not be contaminated by picking up patients, reducing the risk of cross-infection between patients; while the lower isolation pad remains in the operation On the bed, bloodstains or therapeutic drugs remaining on the operating bed will not contaminate the transfer bed due to the isolation of the lower isolation pad, ensuring the hygienic standard of the operating bed when it is used for the second time, and reducing the risk of cross-infection between patients.

(3) The process of extending the upper and lower moving plates when sending the patient: the patient is transferred to the medical transfer bed, that is, the upper moving plate still loads the patient, the ratchet is still unlocked, and the moving bed driving mechanism drives the upper and lower moving plates to move forward. Lateral extension action; since the patient is still pressed on the upper moving cloth, the friction force between the upper moving cloth and the upper moving plate is large enough to overcome the friction generated by the passive movement of the lower moving cloth, resulting in the upper moving cloth and the patient being relatively stationary; at this time , the upper moving cloth, the upper moving plate, the lower moving plate and the patient are all relatively static, the lower moving cloth moves relative to the lower moving plate and the upper moving cloth, but the part of the lower moving cloth in contact with the hospital bed/operating bed is in contact with the hospital bed. / The operating table is still relatively static;

In addition, when the moving bed plate mechanism of the transfer bed is sending the patient to extend the up and down moving plate, the patient and the upper isolation pad move synchronously and laterally with the extension of the up and down moving plate.

In steps (2)-(3), for a thin and light patient, even if the patient presses on the upper moving cloth, the friction force generated by the patient is small, which is not enough to overcome the friction generated by the passive movement of the lower moving cloth, resulting in It may be moved by the lower moving cloth. Therefore, in order to avoid this situation, in steps (2)-(3), a clutch is added to realize the synchronous movement of the moving plate and the locking strip, so as to ensure that the upper moving cloth will not move; and Compared with the two drive mechanisms of Embodiment 1, the power consumption is reduced.

(4) The process of retracting the upper and lower moving plates when sending the patient: When the patient is sent to the top of the hospital bed/operating table, the ratchet locks the locking strip. At this time, the upper moving plate and the lower moving plate are driven by the moving plate driving mechanism. After moving laterally, the upper moving cloth and the contact part between the patient and the patient also remain relatively stationary. Moreover, the contact surfaces of the upper moving cloth and the lower moving cloth also remain relatively static, and the contact part between the upper moving cloth and the patient and the patient also remains relatively static. Except for the relative movement with the corresponding moving plate, there is no other relative movement, and a transfer is completed.

In addition, after the patient is sent to the top of the bed, loosen the upper isolation pad fixed on the locking strip. When the moving bed plate mechanism of the transfer bed retracts the upper and lower moving plates after the patient is sent, the upper isolation pad remains between the patient and the bed. It ensures the isolation between the patient and the hospital bed and reduces the risk of infection.

Infection, it can be seen that the mobile cloth of the existing medical transfer bed cannot be disassembled and cleaned, and it is difficult to achieve the purpose of complete infection prevention. Therefore, the present embodiment 4 provides a medical transfer bed with an easy-to-replace moving cloth. The difference between the medical transfer bed is that the upper moving cloth and/or the lower moving cloth are designed in the form of openings, which can meet the needs of disassembly and replacement, and can prevent infection purpose. The rest of the structure is the same as that of Example 1.

Specifically, compared with Example 1, the difference between the medical transfer bed of Example 4 is that the upper moving cloth is provided with a longitudinal opening; the two sides of the longitudinal opening of the upper moving cloth are respectively connected with rigid limit bars 12; the upper clamping A limit slot is arranged between the bar and the lower clamping bar; the rigid limit bar is installed in the limit slot.

The manner in which both ends of the lower moving cloth are fixed to the bottom of the frame of the vehicle body is preferably fixed by two fixing pieces to respectively fix the cloth heads at both ends of the lower moving cloth. Preferably, as shown in FIGS. 24-25 , the fixing member 13 in this embodiment includes two sets, and each set of the fixing member includes a fixing seat 131 and a rigid fastening strip 132 ; The through slot 1311 through which the moving cloth passes, and the width of the rigid fastening strip is larger than the width of the through slot. In addition, two elongated notches 221 are set on the frame of the vehicle body. After the lower moving cloth covers the outer periphery of the lower moving plate, the cloth openings at both ends of the lower moving cloth pass through the elongated notches, The through grooves of the fixed seat are then respectively fixed with rigid fastening strips and limited to the outside of the through grooves of the fixed seat. Preferably, a groove 1221 is provided on the rigid fastening strip, and after the cloth opening of the lower moving cloth is inserted into the groove, it is fixed on the rigid fastening strip by rivets. As a further preferred solution, each set of the fixing members can also be arranged in sections. As shown in FIG. 25 , in this embodiment, it is divided into three sections, and of course, it can also be divided into two sections. The advantage of segmented fasteners is to increase the rigidity of the body frame.

The above-mentioned embodiments are only the preferred embodiments of the present invention, and the scope of protection of the present invention cannot be limited by this. Any insubstantial changes and replacements made by those skilled in the art on the basis of the present invention belong to the scope of the present invention. The scope of protection of the utility model.
