Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical equipment, in particular to a medical stretcher used for transferring patients. Background Art
[0002] A medical trolley is a device used in medical institutions, mainly for transferring patients. It provides a safe platform that enables medical staff to transfer patients from one location to another, avoiding the risk of patients falling or getting injured during the move. The medical trolley is an indispensable part of the medical process. It ensures that patients can be smoothly transferred from one link to another, ensuring the continuity and efficiency of medical services.
[0003] In the process of implementing this application, the inventor found that there are at least the following problems in this technology:
[0004] (1) The braking system design of the medical trolley is unstable or the braking components are damaged, which may cause the trolley to move unexpectedly when parked, increasing the safety risks for patients and medical staff. Some braking systems are complex in design and require medical staff to spend extra time and energy to operate, which may increase the complexity and difficulty of work. The braking system design of some medical trolleys is unreasonable and may not be able to effectively prevent the trolley from moving when parked, causing the safety of patients on the trolley to be threatened.
[0005] (2) The non-adjustable height of the stretcher may affect the patient's comfort. Patients of different heights and body shapes may need stretchers of different heights to maintain a comfortable posture, but the non-adjustable height of the stretcher cannot meet this demand. Medical staff may need to spend more physical effort to adapt to the fixed height stretcher, such as bending or squatting when transferring patients or providing care. This may increase the labor intensity of medical staff and may lead to occupational injuries. Utility Model Content

[0014] 1. This kind of medical bed for transferring patients, when the bed needs to be pushed, push the connecting hook and rotate it with the fixed rod three as the center of the circle. When the bottom of the rotating connecting hook fits with the outer wall of the fixed rod two, the pushing force on the connecting hook is cancelled, and the elastic potential energy of the damping spring pulls the connecting hook to rotate toward one end of the fixed rod, so that the fixed rod two is hooked in the groove of the connecting hook, and at the same time, the top end of the supporting connecting rod one fits with the bottom end of the supporting connecting rod two, and the hinges one and two on both sides are in a right angle state, so that the pulley at the bottom contacts the bottom surface and is lower than the bottom end of the supporting leg, and the upper end of the medical bed is lifted, so that the pulley is stressed, and the medical bed can be pushed to move. Conversely, when the medical bed is parked, the connecting hook is rotated counterclockwise with the fixed rod three as the center of the circle. The bottom of the connecting hook is disconnected from the surface of the second fixing rod. After the connection is cancelled, the pulley at the bottom cancels the force on the supporting leg, so that the hinges 2 on both sides are hinged and rotated with the hinges 1, driving the supporting connecting rods 1 and 3 to rotate synchronously, so that the bottom end of the pulley moves upward, so that the bottom end of the supporting leg contacts the ground. The switch pulley can be opened or closed at any time as needed, so that the stretcher can be moved when needed and can be fixed in place when needed, which increases the flexibility and versatility of the stretcher. When the stretcher needs to be fixed, closing the pulley can effectively prevent the stretcher from moving accidentally, thereby improving the safety of the patient. Especially when performing medical operations or the patient is resting, fixing the stretcher can prevent unnecessary movement and accidents.
[0015] 2. The medical stretcher used for transferring patients rotates the bidirectional screw to make the two sets of hinged blocks 2 threadedly connected on the outer wall of the bidirectional screw move toward the middle, and the moving hinged block 2 drives the hinged pull rods hinged on both sides to push the hinged block 1 outward, further driving the distance bearings of the two sets of connecting rods 5 to move in opposite directions, driving the supporting pull rod 1 and the supporting pull rod 2 to rotate with the connecting rod 2 as the center of the circle, one end of the rotating supporting pull rod 2 is fixedly connected to the surface of the bottom plate, and the other end drives the connecting rod 3 to slide inside the connecting bracket, and the connecting rod 4 movably sleeved at one end of the supporting pull rod 1 rotates inside the connecting bracket, and the connecting rod 1 movably sleeved at the other end drives The curvature of the bottom limit block on the surface of the limit slide controls the height of the top bed board. Different medical scenarios and operational needs may require stretchers of different heights. The height-adjustable medical stretcher can meet different needs and is suitable for patient transfer and care in various situations. Medical staff can adjust the height of the stretcher as needed to match the height of the operating table, operating bed or other medical equipment, which is beneficial to the operation and nursing work of medical staff and improves work efficiency. Adjusting the height of the stretcher as needed can ensure the appropriate distance and angle between medical staff and patients, which is beneficial to the accuracy and safety of operation and reduces the risk of accidents.

When the push bed needs to be pushed, the connecting hook 17 is pushed and rotated with the fixing rod 3 21 as the center of the circle. When the bottom of the rotating connecting hook 17 is in contact with the outer wall of the fixing rod 20, the connecting hook 17 is canceled. The elastic potential energy of the damping spring 18 pulls the connecting hook 17 to rotate toward the end of the fixing rod 19, so that the fixing rod 20 is hooked in the groove of the connecting hook 17. At the same time, the top of the supporting link 14 fits with the bottom of the supporting link 2 16, and the hinges 12 and 13 on both sides are in a right angle state, so that the pulley 15 at the bottom contacts the bottom surface and is lower than the bottom end of the supporting leg 11, and the upper end of the medical push bed is lifted, so that the pulley 15 is subjected to force, and the medical push bed can be pushed to move.

When the height of the stretcher needs to be adjusted, the two-way screw 27 is rotated to make the two groups of hinged blocks 26 threadedly connected on the outer wall of the two-way screw 27 move toward the middle, and the moving hinged block 26 drives the hinged pull rods 24 hinged on both sides to push the hinged block 1 25 outward, further driving the distance bearings of the two groups of connecting rods 5 29 to move in opposite directions, driving the supporting pull rod 1 7 and the supporting pull rod 2 9 to rotate with the connecting rod 2 10 as the center of the circle. One end of the rotating supporting pull rod 29 is fixedly connected to the surface of the bottom plate 1, and the other end drives the connecting rod 3 23 to slide inside the connecting bracket 3. The connecting rod 4 28 movably sleeved at one end of the supporting pull rod 1 7 rotates inside the connecting bracket 3, and the connecting rod 1 6 movably sleeved at the other end drives the bottom limit block 5 to the surface curvature of the limit slide groove 4, thereby controlling the height of the top bed board 2.
