Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a portable stretcher. Background Art

[0002] A stretcher is a device that facilitates the transfer of patients and injured persons who are lying down. Before transporting the injured, the vital signs and injured parts of the injured person should be checked, with emphasis on checking whether the injured person's head, spine, and chest have any external injuries, especially whether the cervical spine is injured. After placing the injured person on the hard stretcher, the body and the stretcher must be firmly fixed with a triangular bandage or other cloth strips. Especially for those with cervical spine injuries, sandbags, pillows, clothes, etc. must be placed on both sides of the head and neck to fix them and limit the movement of the cervical spine in all directions. Then use a triangular bandage to fix the forehead together with the stretcher, and then use a triangular bandage to surround the whole body with the stretcher.

[0003] The patent document with the announcement number CN 220530242 U discloses a portable stretcher. The portable stretcher is provided with a movable part that can be turned upside down on the connecting part, so that when the stretcher is folded, the movable part can contact the ground, which is convenient for users to carry the stretcher over a long distance and reduces the burden on the staff. After being folded, the portable stretcher needs to be wrapped with a restraining belt, which makes the steps more cumbersome and affects the portability. In addition, a plurality of limiting rings are not designed on the stretcher surface, which easily causes the stretcher surface to be subjected to greater pressure and easily causes the stretcher surface to tear. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a portable stretcher, which can effectively solve the problems of complicated folding steps and easy tearing of the stretcher surface in the prior art.

[0005] The technical solution adopted by the utility model is: a portable stretcher comprises a connector, a rotating shaft 1 is rotatably installed on the outer side of the connector, a front frame is fixedly installed on the outer side of the rotating shaft 1, a limiting ring is arranged on the outer side of the front frame, a stretcher surface is arranged on the other end of the limiting ring, a front restraining belt is fixedly installed on the outer side of the front frame, a fixing column is fixedly installed on the top of the front frame, a magnetic block is fixedly installed on the top of the fixing column, a supporting column is fixedly installed on the bottom of the front frame, a roller is rotatably installed on the outer side of the supporting column, a handle is fixedly installed on the outer side of the support column, a non-slip surface is arranged on the outer side of the handle, a rotating shaft 2 is rotatably installed on the outer side of the rotating shaft 2, a rear frame is fixedly installed on the outer side of the rear frame, a rear restraining belt is fixedly installed on the top of the rear frame, a limiting frame is fixedly installed on the top of the rear frame, a groove is fixedly installed on the top of the limiting frame, a rotating column is rotatably installed inside the connector, a limiting plate 1 is fixedly installed on the top of the rotating column, and a limiting plate 2 is fixedly installed on the bottom of the rotating column.

[0006] Preferably, the limiting rings are provided in equal numbers, and the limiting rings are located on both sides of the front frame and the rear frame and are distributed equidistantly.

[0007] Through the above technical solution and the design of multiple limiting rings, when medical staff and patients lie on the stretcher surface, the multiple limiting rings can disperse the pressure of the stretcher surface and improve the bearing capacity of the stretcher surface, thereby adapting to the use of medical staff and patients of different weights.

[0008] Preferably, the same number of front restraint belts and rear restraint belts are provided, and the two front restraint belts and the two rear restraint belts are symmetrically distributed about the center line of the stretcher surface.

[0009] Through the above technical solution, through the design of the front and rear restraints, when medical personnel and patients lie on the stretcher surface, they can be restrained by the front and rear restraints to prevent them from moving due to pain and to avoid secondary injuries.

[0010] Preferably, the rotating column, the limit plate 1 and the limit plate 2 are in an "I"-shaped structure, and the rotating column, the limit plate 1 and the limit plate 2 are provided in two identical groups, and each group of the rotating column, the limit plate 1 and the limit plate 2 is provided with two identical groups.

[0011] Through the above technical solution, through the design of the rotating column, the limit plate one and the limit plate two, when the stretcher is in use, the limit plate one and the limit plate two can be rotated to limit the front frame and the rear frame, thereby avoiding the front frame and the rear frame from closing. At the same time, when folding is required, the limit plate one and the limit plate two can be rotated to facilitate folding.

[0012] Preferably, the support columns, rollers and handles are provided in two identical groups, one group of support columns, rollers and handles are fixedly mounted on the front frame, and the other group of support columns, rollers and handles are fixedly mounted on the rear frame.

[0014] Preferably, the anti-slip surface is made of rubber material, and the handle has a "round" structure.

[0015] Through the above technical solution, the anti-slip surface made of rubber material can increase the friction between the palms of medical staff and the handles when moving medical staff and patients above, thereby avoiding slipping during the movement process and causing secondary injuries.

[0016] Preferably, the groove is the same size as the magnetic block, and the limit frame is made of iron material.

[0017] Through the above technical solution, when folded, with the design of the groove and the magnetic block, the magnetic block can be inserted into the limit frame, and then the magnetic block can be adsorbed with the limit frame to play a limiting role, thereby preventing the folded stretcher from scattering and affecting normal carrying, thereby improving the overall portability.

[0018] Compared with the prior art, the utility model provides a portable stretcher with the following beneficial effects:

[0019] 1. The portable stretcher is designed with multiple limiting rings. When the medical staff and patients lie on the stretcher surface, the multiple limiting rings can disperse the pressure of the stretcher surface and improve the load-bearing capacity of the stretcher surface, so as to adapt to the use of medical staff and patients of different weights. The front and rear restraint belts are designed so that when the medical staff and patients lie on the stretcher surface, they can be restrained by the front and rear restraint belts to prevent the medical staff and patients from moving due to pain and secondary injuries.

[0020] 2. When the portable stretcher is folded, the design of the rotating column, the limit plate 1 and the limit plate 2 allows the front frame and the rear frame to be limited by rotating the limit plate 1 and the limit plate 2 when the stretcher is in use, thereby preventing the front frame and the rear frame from closing. At the same time, when folding is required, the limit plate 1 and the limit plate 2 can be rotated to facilitate folding. With the design of the groove and the magnetic block, the magnetic block can be inserted into the limit frame, and then the magnetic block can be adsorbed with the limit frame to play a limiting role, thereby preventing the folded stretcher from scattering and affecting normal carrying, thereby improving the overall portability.
