Embodiment 1

[0027] The patient transfer trolley for obstacle and vibration reduction includes a trolley main body 1 on which an infusion stand 11 is installed; the trolley main body 1 is connected with a wheel 2 through a bearing, and a number of supports are connected to the wheel 2. Rod 3, the other end of the rod 3 is provided with a sleeve 4, the rod 3 is sleeved in the sleeve 4, and a damping spring 5 is connected between the rod 3 and the sleeve 4; it also includes a damping wheel body 6 , the ends of several sleeves 4 away from the strut 3 are all connected to the damping wheel body 6 .

[0028] Several struts 3 are connected to the wheel disc 2 of the present invention. When the wheel encounters a bump on the ground, the part of the damping wheel body 6 that is in contact with the ground is squeezed and pushes the sleeve 4 there to move close to the struts 3. The damping spring 5 is compressed here. Due to the local deformation of the damping wheel body 6, the wheels are not thro...

Embodiment 2

[0030] On the basis of Embodiment 1, through holes are provided on the support rod 3 and the sleeve 4, the connecting shaft 21 is fixed on the wheel disc 2, and the engaging disc 7 is sleeved on the connecting shaft 21, and the engaging disc 7 A plurality of connecting rods 71 ​​for passing through the through holes on the sleeve 4 and the through holes on the pole 3 are connected thereto.

[0031] After the wheel of the cart main body 1 rolls over the raised ground, the engaging disc 7 can be pushed to the wheel disc 2, and the connecting rod 71 on the engaging disc 7 passes through the through hole on the pole 3 and the sleeve 4. At this time, the strut 3 cannot move relative to the sleeve 4, and the damping wheel body 6 cannot produce local deformation, so as to ensure the smooth rolling of the vibration damping wheel body 6 on the flat ground and reduce the friction between the vibration damping wheel body 6 and the ground .

Embodiment 3

[0033] On the basis of the first or second embodiment, the connecting shaft 21 is provided with a chute 211 , and the engaging disk 7 is provided with a slider 72 , and the slider 72 is sheathed in the chute 211 .

[0034] During the process of moving the engaging disc 7, the slider 72 always moves in the chute 211, avoiding the rotation of the engaging disc 7 relative to the wheel disc 2, and ensuring that the connecting rod 71 can be accurately inserted into the support rod 3 and the sleeve 4 In the through hole, ensure that the damping wheel body 6 can be locked in time.

Abstract

The invention relates to the field of medical equipment, in particular to a patient transfer cart capable of damping vibration when encountering obstacles. The patient transfer cart comprises a cart body, an infusion stand is mounted on the cart body, a wheel disc is connected on the cart body through a bearing, a plurality of supporting rods are connected on the wheel disc, the other end of eachsupporting rod is provided with a sleeve, each supporting rod is arranged in the corresponding sleeve in a sleeved manner, and damping springs are connected between the supporting rods and the sleeves; the patient transfer cart comprises a damping wheel, and one ends, away from the supporting rods, of the sleeves are connected with the damping wheel. The patient transfer cart can effectively dampvibration when encountering high protrusions, and the problem that existing carts cannot damp vibration when encountering the high protrusions is solved.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a patient transfer trolley for vibration reduction in case of an obstacle. 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 with the patient. Move th...
