There is no magnetism, since the magnetic field will cause the motor to fail, the movements of the embodiments of the present invention are all realized manually.

The working process of the embodiment of the present utility model is:

Step 1. Connect the hospital bed to the transfer vehicle. Place the transfer cart and the hospital bed side by side, turn the side of the handrail assembly to connect with the hospital bed, so that the panel 32 is directly above the hospital bed, pull the disposable film, so that the remaining part of the film is released from the right side of the panel 32, and then put in by the crank handle. The bevel gear drive rod 15 lowers the bed frame 3 until the underside of the panel 32 comes into contact with the bed.

Step 2. Transfer the patient from the bed to the transfer vehicle. By turning the sprocket shaft 27 counterclockwise by the crank, the first chain 61 drives the panel 32 to move to the right. At this time, the lower winding tube 38 rotates clockwise on the second chain 41, the upper winding tube 37 is wound, and the lower winding tube 38 At this time, the conveyor belt 42 located above the panel 32 moves to the left, while the panel 32 scoops the patient up from under the patient, the conveyor belt 42 gradually transports the patient to the panel 32 through friction. After the panel 32 is mounted, the vertical rod 43 of the guardrail assembly is pulled to disengage the belt drive gear 39 from the second chain 41. At this time, rotating the sprocket shaft 27 clockwise drives the panel 32 to move to the left, and the conveyor belt 42 no longer moves. After the panel 32 is reset, the rotatable armrest assembly is pulled up to ensure the safety of the patient.

Step 3. Transfer the patient to the MRI room with a transfer vehicle and perform MRI examination. Push the transfer car to the MRI room. During operation, you can press the brake pedal 26 to make the transfer car go straight or brake, and push the transfer car directly into the MRI detector to check the patient lying on the transfer car.

Step 4. Transfer the patient from the transfer car to the hospital bed. After the inspection, directly transfer the patient to the hospital bed in the ward through the transfer car. First, place the transfer car and the hospital bed side by side. The panel 32 is located directly above the hospital bed. The bevel gear drive rod 15 lowers the bed frame 3 until the lower side of the panel 32 is very close to the bed; the belt drive gear 39 is first disengaged from the second chain 41, and the sprocket shaft 27 is rotated counterclockwise by the crank to drive the panel 32 to move to the right. The center of the hospital bed is shifted to the right, and then the belt drive gear 39 is engaged with the second chain 41. At this time, the sprocket shaft 27 is rotated clockwise, so that the lower belt winding tube 38 is rotated counterclockwise, the lower winding tube 38 is wound, and the upper winding The belt tube 37 is loosened, and the conveyor belt 42 located above the panel 32 moves to the right, so that while the panel 32 moves to the left, the conveyor belt 42 gradually pushes the patient out of the panel 32 to the hospital bed, completing the transfer of the person from the transfer vehicle to the hospital bed. work.

The patient transfer vehicle with reversible handrails according to the embodiment of the present invention can directly carry out nuclear magnetic resonance examination without manual assistance and without changing the bed, greatly shortening the examination time of a single patient, and effectively improving the nuclear magnetic resonance apparatus. The utilization efficiency of the hospital saves the purchase cost of the hospital's equipment.

It can be seen from the whole transfer process that as the panel 32 moves to the right, the frame 1 under the panel 32 will be leaked out, which will affect the beauty of the entire transfer vehicle. At the same time, small things are easy to fall and cause safety hazards. In order to solve the above problems , the embodiment of the present utility model is also provided with a shielding mechanism capable of adapting to the movement of the panel 32, the shielding mechanism includes: a sealing plate transverse tube 62 fixedly installed on the upper part of the reel frame 31, an upper guide roller fixedly installed on the left side of the bed frame 3 63 and lower guide rollers 64, two side-by-side lower right guide rollers 65 and upper right guide rollers 66 that are fixedly installed on the right side of the bed frame 3, and a sealing plate fixing shaft 67 that is fixedly installed at the lower part of the reel frame 31 The sealing plate horizontal pipe 62, the lower guide roller 64, the upper guide roller 63, the lower right guide roller 65, the upper right guide roller 66 and the sealing plate fixing shaft 67 are arranged parallel to each other. One end of a cloth tape is fixedly connected to the horizontal tube 62 of the sealing plate, and then goes around the upper guide roller 63, the lower guide roller 64, the lower right guide roller 65 and passes through the lower right guide roller 65 and the upper right guide roller 66. After the gap therebetween, the other end of the cloth tape is fixedly connected to the fixing shaft 67 of the sealing plate. In this way, both ends of the cloth tape are fixed on the reel frame 31. During the movement of the panel 32, the shortened distance between the sealing plate fixing shaft 67 and the lower right guide roller is exactly equal to the sealing plate transverse tube 62 and the upper guide roller. The stretched distance between 63 keeps the length of the entire cloth tape unchanged, and the cloth tape between the sealing plate transverse tube 62 and the upper guide roller 63 compensates the rightward movement distance of the panel 32 in real time, and the transfer vehicle is in the process of use The parts below the panel 32 can never be seen, which increases the user's sense of security and prevents the fine items from falling into the transfer vehicle and affects the operation of the transfer vehicle.

It should be understood that the specific embodiments described above are only used to explain the present invention, and are not used to limit the present invention. Obvious changes or changes derived from the spirit of the present invention are still within the protection scope of the present invention.
