Description

Technical Field

[0001] The utility model relates to the technical field of stretcher fixing devices, in particular to a transfer stretcher fixing device. Background Art

[0002] With the continuous progress of medical technology and the increasing improvement of medical services, the research and development and upgrading of medical equipment are crucial for improving medical efficiency and patient safety. As a key component of medical equipment, the design and production of transfer stretchers have a decisive impact on the timely transfer and safe treatment of patients.

[0003] After retrieval, the patent with the authorization announcement number CN219878476U proposes a vehicle-mounted stretcher fixing device. The following problems exist in this technical solution:

[0004] To a certain extent, this device solves the problem that there are still a large number of gaps between the stretcher and the interior of the vehicle body, so that when the vehicle is driving, the stretcher body is prone to shaking and other situations. However, the shaking inside the vehicle body is not only lateral shaking but also vertical bumping shaking. This device lacks the weakening of vertical shaking, so that patients are still affected by bumping shaking during transportation.

[0005] In view of the above problems, the utility model document proposes a transfer stretcher fixing device. Utility Model Content

[0006] The utility model provides a transfer stretcher fixing device, which solves the disadvantages in the prior art that the shaking inside the vehicle body is not only lateral shaking but also vertical bumping shaking, and this device lacks the weakening of vertical shaking, so that patients are still affected by bumping shaking during transportation.

[0007] The utility model provides the following technical solutions:

[0008] A transfer stretcher fixing device includes a mounting seat. A lifting seat is arranged at the top of the mounting seat. Slide grooves are formed in the inner walls on both sides of the lifting seat. Two slide bars are respectively slidably connected to the two slide grooves. A bottom plate is fixedly connected between the two slide bars. A support frame is arranged at the top of the bottom plate;

[0009] A shock absorption mechanism is arranged at the top of the bottom plate and is used for stabilizing the patient when the vehicle passes through a bumpy section during the transportation of the patient, and reducing the secondary injury caused by vehicle bumping to the patient;

[0010] A lifting mechanism is arranged inside the mounting seat and is used for lifting the patient when the patient enters the carriage and adjusting the patient to a height convenient for medical staff to treat.

[0011] In a possible design, the shock absorption mechanism includes a lifting airbag, a first air pipe, a second air pipe, an air pump, a relief valve, and a damping buffer. The bottom of the lifting airbag is fixedly connected to the top of the bottom plate, and the top of the lifting airbag abuts against the bottom of the support frame. Both ends of the first air pipe are communicated between multiple lifting airbags. One end of the second air pipe is fixedly communicated with the first air pipe, and the other end of the second air pipe is communicated with the output end of the air pump. The bottom of the air pump is fixedly connected to the top of the bottom plate. The relief valve is arranged on one of the lifting airbags. One end of the damping buffer is fixedly connected to the top of the bottom plate, and the other end of the damping buffer is fixedly connected to the bottom of the support frame.

[0012] In a possible design, a positioning plate is fixedly connected to the top of the bottom plate, and a limiting plate is fixedly connected to the bottom of the support frame. A limiting groove is opened on one side of the positioning plate, and one side of the limiting plate is slidably connected to the inside of the limiting groove.

[0013] In a possible design, the lifting mechanism includes a motor, a bidirectional lead screw, a fixed block, a lead screw nut, a lifting rod, and a support plate. One side of the motor is fixedly connected to the inner wall of one side of the mounting seat. One end of the bidirectional lead screw is fixedly connected to the output end of the motor through a coupling, and the other end of the bidirectional lead screw is rotatably connected to the inner wall of the other side of the mounting seat through a rotating shaft. The bottom of the fixed block is fixedly connected to the inner wall of the bottom of the mounting seat. A rotating hole is opened inside the fixed block, and the bidirectional lead screw passes through the rotating hole. The fixed block is arranged at the middle part of the bidirectional lead screw. Two lead screw nuts are threadedly connected to the outer wall of the bidirectional lead screw. The bottom of the lead screw nut is fixedly connected with a slider. A guiding groove is opened on the inner wall of the bottom of the mounting seat, and the slider is slidably connected in the guiding groove. Two push rods are fixedly connected to the outer wall of the lead screw nut. One end of each of the two lifting rods is rotatably connected to the outer wall of the push rod, and the other end of the lifting rod is hinged to the bottom of the support plate. Two support plates are fixedly connected to the bottom of the lifting seat.

[0014] In a possible design, a plurality of telescopic rods are fixedly connected to the bottom of the lifting seat, and the other ends of the telescopic rods are fixedly connected to the inner wall of the bottom side of the mounting seat. One side of the mounting seat is in a triangular slope shape.

[0015] In a possible design, one end of the sliding strip is conical, and the opening of the sliding groove is in an eight-shaped shape for better guiding the sliding strip into the sliding groove. Protective fences are fixedly connected to both sides of the support frame to prevent the patient from falling.

[0016] In this application, before use, first fix the base of the device to the transport vehicle through bolts. When in need of use, pull out the stretcher from the lifting seat, place the patient to be transferred on the stretcher, and then push the stretcher into the chute of the lifting seat by using the sliding bar provided on the stretcher. The triangular slope on one side of the mounting seat makes it more convenient to push the stretcher. One end of the leg at the bottom of the stretcher is hinged to the bottom of the bottom plate, and the other end is fixedly connected to a universal wheel. A buckle is provided at the bottom of the bottom plate to lock the leg after folding or extending. At this time, the stretcher is fixed on the lifting seat. If the road surface is bumpy, the air in the lifting airbag can be released by using the air release valve. At this time, the lifting airbag no longer abuts against the support frame, and the weight of the patient on the support frame falls on the damping buffer at this time. The damping buffer can reduce the bumps when there are bumps. If the shock absorption function is not needed, use the air pump to inflate the lifting airbag through the second air pipe and the first air pipe, so that the weight on the support frame falls on the lifting airbag again. When the patient on the stretcher needs treatment, since the legs of the stretcher are folded at this time, the height of the stretcher is relatively low, which is not convenient for medical staff to treat. At this time, start the motor. The motor drives the double lead screw to make the two lead screw nuts approach each other, so that the push rod on the lead screw nut pushes the lifting rod to raise the tray. The rising of the tray raises the lifting seat, and the lifting seat raises the entire stretcher, so as to adjust the patient to a convenient treatment height.

[0017] In the present utility model, for the described transfer stretcher fixing device, through the shock absorption mechanism, the effect of reducing the bumps suffered by the patient on the transport vehicle can be achieved, improving the comfort of the patient and avoiding the risk of secondary injury to the patient caused by bumpy shaking.

[0018] In the present utility model, for the described transfer stretcher fixing device, through the lifting mechanism, the effect of adjusting the height of the stretcher can be achieved, so as to adjust the patient to a suitable treatment height, improving the convenience of treating the patient.

[0019] In the present utility model, it solves the problem that the shaking inside the vehicle body is not only lateral shaking, but also vertical bumpy shaking, and the device lacks the weakening of vertical shaking, so that the patient is still affected by bumpy shaking during transportation.
