Embodiment 1

[0028] The patient transfer trolley that brakes smoothly and is convenient for the patient to get out of bed includes a main body 1 of the trolley; a sleeve 2 is connected to the main body 1 of the trolley, and a buffer rod 3 is set inside the sleeve 2, and the buffer rod 3 and the sleeve A buffer spring 4 is connected between them, the other end of the buffer rod 3 is connected with a rear wheel frame 5, the rear wheel frame 5 is connected with a rear wheel 51 through a bearing, and two brake frames 6 are hinged on the rear wheel frame 5, and the two brake frames 6 are hinged. A return spring 7 and a brake hydraulic assembly 8 that pushes the brake frame 6 to tilt are respectively connected between the moving frames 6, and the brake hydraulic assembly 8 is installed on the rear wheel frame 5; one end of the cart body 1 is hinged with a rotating plate 13 , the rotating plate 13 is fixed with an arc frame 14, the arc frame 14 takes the hinge point of the cart main body 1 and the...

Embodiment 2

[0031] On the basis of Embodiment 1, the brake hydraulic assembly 8 includes a two-way hydraulic cylinder 81, which is fixed to the rear wheel frame 5, and the two piston rods of the two-way hydraulic cylinder 81 are respectively hinged to a brake frame 6. The liquid inlet of the hydraulic cylinder 81 is connected with the main hydraulic cylinder 82 through a hydraulic pipe.

[0032] When braking is required, the main hydraulic cylinder 82 is driven to act, the hydraulic oil in the main hydraulic cylinder 82 is pressed into the two-way hydraulic cylinder 83, and the two piston cylinders of the two-way hydraulic cylinder 83 push the brake frame 6 outward, and the brake frame 6, the rear wheel 51 can be braked. Driven by hydraulic pressure, the brake is more reliable and easy to operate. After the braking is completed, the back-moving spring 7 can draw the two brake frames 6 together to release the brake.

Embodiment 3

[0034] On the basis of Embodiment 1 or Embodiment 2, the piston rod of the main hydraulic cylinder 82 is connected with a slider 83, and the rear wheel frame 5 is provided with a chute 52, and the slider 83 is sleeved in the chute 52. A handle 84 is connected to the block 83 , and a release spring 85 is connected between the slide block 83 and the rear wheel frame 5 .

[0035] When braking is required, the hydraulic oil in the main hydraulic cylinder 81 can be pressed into the two-way hydraulic cylinder 82 by pulling the handle 84 to realize the braking operation of the brake frame 6 . After the brake is stopped, the release spring 85 can reversely pull the slide block 83 to ensure that the main hydraulic cylinder 81 and the two-way hydraulic cylinder 82 reset quickly, and ensure that the back-moving spring 7 can pull the two brake frames 6 back to their original positions in time.

Abstract

The invention relates to the field of medical equipment, in particular to a patient transfer cart with stable braking and good convenience for a patient to get out of a bed. The patient transfer cartcomprises a cart body; the cart body is connected with sleeves; a buffer rod is nested in each sleeve; a buffer spring is connected between each buffer rod and the corresponding sleeve; the other endof each buffer rod is connected with a rear wheel carrier; a rear wheel is connected to each rear wheel carrier through a bearing; two brake racks are hinged to each rear wheel rack; a return spring and a braking hydraulic component to push the brake racks to tilt are connected between the two brake racks, and the braking hydraulic component is mounted on the corresponding rear wheel carrier; a rotating plate is hinged to one end of the cart body; an arc rack is fixed to the rotating plate; the arc rack uses a hinging point of the cart body and the rotating plate as a center of circle; the arcrack is provided with a plurality of through holes; the arc rack is connected with a cart body pin through a through hole. The patient transfer cart that can provide buffering to avoid bumping and allow a patient to get out of bed conveniently is provided.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a patient transfer trolley which brakes smoothly and is convenient for patients to get out of bed. Background technique [0002] Patient trolleys are one of the indispensable medical facilities in clinical practice. They are widely used to push patients for examination, pick up patients for surgery, etc. Before and after the operation, the patient needs to be lifted from the bed in the ward to the trolley and then pushed to the operating table in the operating room, or transported back to the bed in the ward from the operating table in the operating room. In the actual operation process, the patient is lifted onto the trolley and pushed out of the operating room door before the operation. After the trolley is connected with the trolley in the operating room, in order to reduce the number of times of lifting and the pain of the patient, the bed board is often directly connected wi...
