Description

Technical Field

[0001] The utility model relates to the technical field of first aid care, in particular to a nursing transfer cart which is convenient to fold up and push. Background Technique

[0002] Emergency treatment in emergency situations is divided into emergency treatment and rescue. Its existence ensures that we can receive professional and scientific treatment in the shortest time when suffering from sudden diseases or accidental injuries. In emergency treatment, most patients are transferred to the intensive care unit for observation through a transfer cart.

[0003] The structure and size of the existing transfer cart cannot be changed. When pushing an empty cart, it is often unable to move quickly because it needs to avoid other patients in the hospital. The large empty cart will affect the moving speed and thus increase the arrival time, and it also occupies a relatively large space when not in use.

[0004] Therefore, it is particularly important to design a nursing transfer cart that is convenient to fold up and push to overcome the above technical defects and improve the overall practicality. Content of the Utility Model

[0023] For the embodiments, please refer to Figures 1-3 , the present utility model provides a technical solution:

[0024] A nursing transfer cart that is convenient to fold up and push includes a fixed push frame 1. At the left and right ends of the front side of the fixed push frame 1, support pipe sleeves 101 are connected. At the front end of the outer side of the support pipe sleeve 101, a gear seat 102 is installed. At the top of the gear seat 102, a forward and reverse motor 103 is installed. The output end of the forward and reverse motor 103 penetrates through the inside of the gear seat 102 and is connected to a gear 104. On the front side of the fixed push frame 1, a movable push frame 2 is provided. At the left and right ends of the rear side of the movable push frame 2, telescopic support rods 201 are connected. On the outer side of the telescopic support rod 201, a rack 202 extending along the length direction of the telescopic support rod 201 is provided. Inside the fixed push frame 1 and the movable push frame 2, support crossbars 3 are connected. At the bottom of the support crossbar 3, movable vertical frames 4 are installed. At the bottom of the movable vertical frames 4, traveling wheels 5 are symmetrically installed on the left and right. Above the fixed push frame 1 and the movable push frame 2 and at the top of the support crossbar 3, mattresses 6 are placed symmetrically in the front and rear.

[0025] A pushing handle is connected to the middle position at the top of the fixed pushing frame 1 for pushing and moving. The walking wheels 5 are designed as lockable universal wheel structures, facilitating movement and locking. The connection between the support pipe sleeve 101 and the telescopic support rod 201 is a sliding connection. The internal structure size of the support pipe sleeve 101 is adapted to the external structure size of the telescopic support rod 201. The connection between the rack 202 and the gear 104 is a meshing connection. The meshing of the gear 104 and the rack 202 causes the telescopic support rod 201 to slowly extend from the support pipe sleeve 101.

[0026] In this embodiment, please refer to Figure 3 , rotating blocks 601 are connected to the facing sides of the two groups of mattresses 6. Hinge plates 602 are rotatably connected between the left and right sides of the two groups of rotating blocks 601. A counterweight bar 603 is embedded at the front end of the top of the mattress 6 at the front side, which can cause the front mattress 6 to fall due to gravity when folding and erecting, and overlap with the other mattress 6. A folding bracket 604 is installed on the left side of the rotating block 601 at the front side. A rotating motor 605 is arranged inside the folding bracket 604. A shaft rod 606 is fixed at the shaft hole of the hinge plate 602 on the right side. One end of the shaft rod 606 and the output end of the rotating motor 605 are both connected with driving gears 607 that mesh with each other;

[0027] A controller is installed at the rear side of the fixed pushing frame 1. The controller is electrically connected to the forward and reverse motor 103 and the rotating motor 605 through wires. The mattress 6 is made of medical sponge material, and the inside of the counterweight bar 603 is filled with counterweight lead bars, having gravity guidance.

[0028] The working process of the present utility model: When this transfer cart is used in emergency care, usually the transfer cart is in a retracted and shortened state, and the two layers of mattresses 6 are stacked on top of each other. The overall length of the transfer cart in the retracted state is half of the overall length of the transfer cart in the unfolded state. It is more convenient to move when pushing the empty cart compared to the original transfer cart. When reaching the designated location, start the forward and reverse motor 103, and the meshing of the driving gear 104 and the rack 202 causes the telescopic support rod 201 to slowly extend from the support pipe sleeve 101. When fully extended, stop. Then, drive the two groups of driving gears 607 to mesh under the drive of the rotating motor 605, so that the shaft rod 606 drives the hinge plate 602 to rotate by 90 degrees. Then, with the cooperation of the rotating block 601, the two groups of mattresses 6 are flattened, and the patient is moved onto the mattress 6.

[0029] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
