Description

Lifting type transfer vehicle for seriously ill patients and method of using the same

technical field

The invention relates to a medical transfer vehicle, which is mainly used for transferring critically ill patients between a sickbed and an examination table or an operating table, and more particularly, to a hoisting transfer vehicle for severely ill patients and use thereof method.

Background technique

Severely ill patients often need to perform various examinations and operations, etc., and need to use a transfer vehicle to transfer the patient between the ward, the examination room, and the operating room. The function of the transfer vehicle is to transfer the patient from the hospital bed to the examination table or operating table . At present, most of the transfer vehicles (transfer beds) in hospitals are single beds (stretchers) with casters. When transporting patients, family members and medical staff are required to lift the sheets, use the sheets to transport the patients to the transfer vehicles, and then After being pushed to the examination room or operating room, family members and medical staff will carry the patient's bed sheet to the examination table or operating table. It takes 3 to 5 people to complete the patient's getting on and off each time, which is easy to cause the nursing staff in the ward to get on and off. It is too noisy, and the work order is disordered, which affects the recovery of the patient; in addition, it causes a large amount of waste of personnel, and because of the large number of people and hands, it is easy to cause secondary damage to the patient during the handling process.

In view of the above-mentioned defects existing in the existing patient transfer vehicles, the existing technicians have proposed improved solutions. For example, the applicant has filed a patent number ZL201610892620.X on October 12, 2016, and the name of the invention is: a patent application for a plug-in patient transfer vehicle. In this application, the plug-in patient transfer vehicle is mainly composed of a bottom frame. , The lifting device installed on the bottom frame, the support frame installed on the lifting device, the plate frame, the two or more plug-in boards, the plug-in plate translation mechanism, the plug-in board tilt mechanism and the board frame tilt mechanism, the plug-in board is translated through the plug-in board The mechanism is installed on the board frame, the plug board tilting mechanism is arranged below the plug board, the board frame tilt mechanism is set between the support frame and the board frame, and the board frame and the support frame are rotatably connected. When in use, the inserts are inserted into the lower part of the patient's body in turn. After the previous insert is inserted under the patient's body, it can be inclined at a certain angle to form a gap between the patient's body and the bed surface, so that the next insert can be easily inserted, and the operation can be completed by one person. , easy to use, can effectively prevent the patient from secondary injury. However, the transfer action of this application is relatively complicated, the inserting board needs to perform many actions, and it takes a long time to transport the patient at a time. The relatively complicated mechanism also causes high production costs and high failure rate.

Another example is the Chinese Patent No. ZL200420064433.5, which was retrieved and named as: Patent Application for Lifting-type Surgical Transporter, which was announced and authorized on October 5, 2005, with a set of lifts at each end of the vehicle. There is a set of translation mechanism composed of upper and lower cantilevers at the upper end of the lifting mechanism, a hanging plate at one end of the lower cantilever, two rolling rollers under the two hanging plates, and a through groove on the rolling rollers. A pressing rod is installed in the through groove, and there are hooks on the roll, which can roll the sheets on the operating table tightly on the roll to form a stretcher-like mechanism, transport the patient away, and release the roll after the bed By leaving the patient and bed sheets on the bed, the patient after surgery can be smoothly transported from the operating table to the bed without moving the body, which reduces the possible damage caused by moving the patient and reduces the labor intensity of medical staff. This application proposes to use two sets of rolls to clamp the bed sheet to achieve patient transfer. This method does not need to directly contact the patient, so it has better safety. However, in this application, the two sets of rolls use The translation mechanism composed of the upper and lower cantilevers performs extension and retraction actions. On the one hand, the translation mechanism composed of the upper and lower cantilevers has poor load-bearing capacity, especially when the upper and lower cantilevers are extended for a long distance. The load is larger, and it is difficult to support the weight of a patient. In the process of lifting the patient and retracting the patient, the upper and lower cantilevers are difficult to retract due to the cantilever force, which is very inconvenient to use; on the other hand, the two sets of rolls are outward When it is extended to lift the patient, due to the effect of the large cantilever, there is no suitable support, so the problem of overturning of the truck is easy to occur during use; in addition, the structure of the truck is complicated, the operation is inconvenient, and the production cost is relatively high. When the two groups of rollers clamp the bed sheet and directly lift the patient, the weight of the patient is borne by the bed sheet, and there is a potential safety hazard that the bed sheet is cracked and the patient falls and causes secondary injury, and the use safety is poor.

Extend the telescopic bed board (3-1) toward the target bed, so that the telescopic bed board (3-1) is located under the patient's body, and at the same time drive the patient down through the lifting and lowering mechanism (4), and the supporting mechanism (7) Synchronized contraction, place the patient flat on the telescopic bed board (3-1); a-6. Control the support mechanism (7) to retract upward, retract the telescopic bed plate (3-1) and the translation frame (5) at the same time, and lock the telescopic bed plate (3-1) to complete the transfer of the patient from the target bed to the transfer vehicle transfer work; B. Transfer the patient from the transfer vehicle to the target bed: b-1. Push the transfer car to the side of the target bed and stop it firmly, so that the extended side of the telescopic bed (3-1) of the transfer car is close to the target bed; b-2. Control the heights of the telescopic bed plate (3-1) and the translation frame (5) through the scissor lift mechanism (2) and the lifting and lowering mechanism (4) respectively, so that the height of the telescopic bed plate (3-1) is slightly higher than The height of the bed surface of the target bed body, the height of the translation frame (5) is higher than the lying height of the patient; b-3. Extend the telescopic bed board (3-1) together with the translation frame (5) toward the target bed, so that the telescopic bed board (3-1) moves the patient to the center of the target bed; The two sides of the sheet on (3-1) are respectively curled to the electric drum (6) on the corresponding side, and then the electric drum (6) is driven in two opposite directions to make the sheet in a taut state; b-4. Control the support mechanism (7) to extend downward to make it support on the target bed; then control the translation frame (5) to rise to a certain height through the hoisting and lifting mechanism (4), and the support mechanism (7) synchronizes Extend, use the sheet to lift the patient off the telescopic bed (3-1); b-5. Retract the telescopic bed board (3-1), at the same time drive the patient to lower through the lifting and lowering mechanism (4), the support mechanism (7) shrinks synchronously, and lay the patient flat on the target bed; b-6. Loosen the bed sheet, retract the support mechanism (7) upward, and then retract the translation frame (5) to complete the transfer of the patient from the transfer vehicle to the target bed.
