Description

intensive care bed

technical field

The invention relates to the technical field of medical beds, in particular to a nursing bed for critically ill patients.

Background technique

Many elderly people, paralyzed patients, and critically ill patients often cannot take care of their own stool due to inconvenient movement, and need other people's care while lying on the hospital bed. In order to solve the inconvenience of stool care, the Chinese utility model patent No. 201520039687.X discloses a new type of hospital bed. The bed is provided with a toilet at the bottom of the bed board at the position corresponding to the buttocks. In this way, when the patient needs to defecate, it can be solved directly without the need for the nursing staff to take the basin, which effectively reduces the difficulty of nursing. It is well known that bowel movements are more difficult when the patient is lying flat. During the use of the hospital bed, when the patient reminds that there is an intention to defecate, the nursing staff needs to shake the hand to turn the back bed board up, and adjust the patient to a sitting state, so that the patient can defecate smoothly. Therefore, although this kind of bed reduces the difficulty of nursing to a certain extent, in the process of use, the nursing staff still needs to accompany the sick bed at all times to assist the patient to defecate, which cannot fundamentally liberate the nursing staff. In addition, there is another problem with this hospital bed. Because the users are all young people, paralyzed patients, and critically ill patients, their balance is relatively poor, and some even completely lose it. When the patient adjusts to sit up, it is easy to fall to one side. Therefore, when the patient sits up, the nurse needs to support the patient to help maintain balance, otherwise the patient will be injured twice due to falling. This increases the work of the nursing staff.

The present invention will be further elaborated below by means of the accompanying drawings and examples.

As shown in FIG. 1 : a nursing bed for critically ill patients, including a bed frame 1 , a bed board, and an electric push rod-2. Bed board comprises back bed board 3 and buttocks bed board 4, and it is installed on the bed frame 1. The back bed board 3 can be turned upwards and reset under the action of the electric push rod-2. A toilet 10 is installed on the bottom of the buttocks bed board 4 . The above is the prior art, not the key point. The first invention point of the present invention is to add a controller 8 and a signal sensor 9 to improve the intelligence of the nursing bed. Wherein, the signal sensor 9 is installed inside the toilet 10 for detecting whether there is stool falling. The signal sensor 9 is connected with the controller 8, and the controller 8 is connected with the electric push rod-2 for controlling the start and stop of the electric push rod-2. The kind of controller 8 is not the key point, and it can adopt conventional single-chip microcomputer or PLC.

The bed board also includes a leg bed board 5 and a foot bed board 6 which are transferred to each other. Leg bed board 5 and foot bed board 6 are connected by connecting rod three 13. The bottom of bed board is equipped with electric push rod two 12. Driven by the electric push rod 2 12, the leg bed 5 can be turned down 90 degrees, and the foot bed 6 is driven down through the connecting rod 3 13, and then the back bed 3 can be turned upward to adjust the patient to the optimal position. Comfortable sitting posture, so as to ensure the comfort of the patient when defecating to the greatest extent. The controller 8 is connected with the electric push rod two 12, and is used to control the start and stop of the electric push rod two 12.

During specific implementation, the signal sensor 9 can be an infrared sensor, and its receiver and transmitter are relatively installed on both sides inside the toilet 10 . When the patient begins to defecate, and part of the defecation falls into the toilet 10 , the infrared sensor can detect the defecation signal, and transmit the detected signal to the controller 8 . After receiving the signal, the controller 8 controls the electric push rod 1 2 and the electric push rod 2 12 to work, the back bed board 3 is turned up, the leg bed board 5 is turned down, and the whole bed board is transformed into a chair, so that the patient is sitting up. State, thereby promoting the patient's defecation. When the infrared sensor does not detect that there is stool falling for a period of time (the time can be preset in the controller 8, such as 5 minutes), the controller 8 controls the back bed board 3, the leg bed board 5, and the foot bed board 6 to reset, and the patient Adjust to lie flat.

The toilet 10 has its own flushing mechanism and drying mechanism (the prior art). In order to further improve the intelligence of the toilet 10 and reduce the work of nursing staff, the flushing mechanism and the drying mechanism can be connected to the controller 8 together. When the infrared sensor does not detect that there is stool falling for a period of time (the time can be preset in the controller 8, such as 5 minutes), the controller 8 controls the flushing mechanism and the drying mechanism to start to flush and dry the patient's buttocks. Dry, clean the patient's buttocks as quickly as possible.

In addition, a liquid level sensor connected to the controller 8 can also be installed in the toilet 10 . When it is detected that urine flows into the toilet 10, the liquid level sensor transmits a signal to the controller 8, and the controller 8 controls the bed board to be adjusted to the seated state, so as to promote the patient to urinate.

As shown in Fig. 2 and Fig. 3: the second inventive point of the present invention lies in the improvement to the back bed board 3, to prevent the patient from toppling over when sitting up. The back bed board 3 includes a back board 31 located in the middle and side fences 32 hinged on both sides of the back board 31 . A drive mechanism 7 is installed at the junction of each side fence 32 and the backrest board 31 . When the backrest board 31 is turned up, the two side panels 32 can be turned inward under the action of the corresponding drive mechanism 7 to form a side panel, so as to prevent the patient from sitting up and keep the patient in an upright position all the time. .

In this embodiment, the drive mechanism 7 is composed of a shaft sleeve 71, a shaft one 72, a shaft two 73, a bearing 74, a connecting rod one 75, a connecting rod two 76, a guide plate 77, a connecting piece 78 and other components. Wherein, the shaft sleeve 71 is arranged along the length direction of the side baffle 32 , and is fixedly connected to the backrest plate 31 through a connecting piece 78 , and the shaft one 72 is installed in the shaft sleeve 71 and can rotate in the shaft sleeve 71 . One end of connecting rod one 75 is hinged with side panel 32, and the other end is hinged with one end of connecting rod two 76, and the other end of connecting rod two 76 is affixed with axle one 72 near the end of the bed. Axle two 73 are connected to an end of axle one 72 near the end of the bed, and are perpendicular to axle one 72, and bearing 74 is installed on the axle two 73. The guide plate 77 is fixed on the bed frame 1 and has a guide surface 1 771 close to the head of the bed and a guide surface 2 772 connected to the guide surface 1 771 near the end of the bed. Wherein, the first guide surface 771 is parallel to the side of the backrest board 31 , and the second guide surface 772 is inclined toward the center of the bed frame 1 . The bearing 74 is rollingly fitted on the first guide surface 771 or the second guide surface 772 .

The back bed board 3 is turned up: as the backrest board 31 slowly rises, the bearing 74 rolls and fits on the guide surface 2 772, and drives the shaft 1 72 to rotate; the shaft 1 72 rotates to drive the connecting rod 2 76 with the shaft 72 as The center of the circle rotates; the rotation of the second connecting rod 76 drives the rotation of the first connecting rod 75, so that the angle between the first connecting rod 75 and the second connecting rod 76 increases slowly, and then the first connecting rod 75 drives the side baffle 32 to slowly turn inwardly; Along with the continuous rise of the backrest plate 31, when the bearing 74 rolls from the guide surface 2 772 to the guide surface 1 771, the shaft 1 72 no longer rotates. state (see Figure 2).

The back bed board 3 is reset: as the back board 31 slowly descends, the bearing 74 rolls and fits on the guide surface 771, and during this process, the shaft 72 does not rotate; as the back board 31 continues to descend, when the bearing 74 When rolling from guide surface 1 771 to guide surface 2 772, shaft 1 72 starts to reversely rotate, and drives connecting rod 2 76 to reversely rotate with shaft 1 72 as the center of circle; connecting rod 2 76 reversely rotates to drive connecting rod 1 75 Reverse rotation makes the angle between the first connecting rod 75 and the second connecting rod 76 decrease slowly, and then the first connecting rod 75 drives the side baffle 32 to slowly turn outward; when the backrest 31 is fully reset, the side baffle The plate 32 also happens to be completely flat (see FIG. 3 ).

Through the driving mechanism 7 designed in the above structure, the side baffle 32 can be turned over and reset automatically with the lifting of the back bed 3, and no additional actuator is required to drive the side baffle 32. The operation is convenient, the structure is simple, and the cost is low. .

As shown in Fig. 4 and Fig. 5: the third invention point of the present invention is to improve the bed board, so that the nursing bed has the function of turning over automatically. The bed board is made up of a central bed board 14 in the middle and side bed boards 15 hinged on both sides of the central bed board 14 . The bed frame 1 is rotatably provided with a rollover frame 16 , and the central bed board 14 rests on the rollover frame 16 . The outer sides of the two side bed boards 15 are always movably overlapped on both sides of the bed frame 1 . The bottom of bed board is equipped with electric push rod three 17, and electric push rod three 17 links to each other with rollover frame 16, is used for driving rollover frame 16 to turn over, reset. The side turning frame 16 can turn over under the effect of the electric push rod three 17, and then drive the center bed board 14 to turn over, thereby realizing the automatic turning over of the patient. In the process of turning over the center bed board 14, the side bed board 15 on one side and the center bed board 14 are turned over in the same direction synchronously, and the side bed board 15 on the other side is turned over at a certain angle synchronously with the center bed board 14 to form a certain angle with the center bed board 14. Angle (seeing Fig. 5), at this moment, the side bed board 15 supports the patient and bears most of the weight of the patient. For the back bed board 3, its backrest board 31 and side board 32 can be used as a part of the central board 14 and side board 15 respectively, so that the side board 32 not only has the effect of preventing the patient from toppling over, but also has the function of assisting the patient to roll over. effect.

In order to further improve the intelligence of the nursing bed, in the present embodiment, the electric push rod 3 17 is connected with the controller 8 and is controlled by the controller 8 . Before use, the rollover time can be preset in the controller 8, such as 15 minutes. Then every 15 minutes, the bed board is controlled by the controller 8 to roll over once for the patient to stand up.

As shown in FIG. 6 : in addition, the toilet 10 is provided with a urine shield 11 , and the urine shield 11 can slide freely along the width direction of the toilet 10 . When the bed board rolls over, people will also slide to the lower side thereupon. The urine shield 11 is designed as a sliding structure, so that the urine shield 11 can move synchronously with the lower body of the patient, thereby preventing the patient's lower body from being stuck on the urine shield, and reducing the impact of the urine shield 11 on the comfort of the patient .
