Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a novel multifunctional stretcher bed. Background Technology

[0002] In medical transport scenarios, existing stretcher beds have many shortcomings. Traditional stretcher beds have a fixed structure and the height of the support legs cannot be adjusted, making it difficult to achieve seamless connection when facing hospital beds or ambulance compartments of different heights, increasing the risk of patient transport. When transporting patients on special terrains such as stairs or rough roads, ordinary stretcher beds cannot maintain a horizontal position, causing patient discomfort and even risking worsening of their condition. Moreover, traditional stretcher beds have limited functionality and lack positioning and fixation measures for patients with different conditions.

[0003] For example, in patients with fractures, the inability to effectively immobilize the limbs can easily cause secondary injuries;

[0004] For patients with poor cardiopulmonary function, it is difficult to adjust to a suitable breathing position.

[0005] In addition, existing stretcher beds are not convenient for handling, resulting in high labor intensity and low efficiency for medical staff.

[0006] These issues urgently need to be addressed to improve the safety and efficiency of medical transport.

[0007] This utility model addresses these issues by proposing a novel multifunctional stretcher bed, aiming to solve the aforementioned problems. This device meets the positioning needs of patients with different conditions, provides comprehensive protection for patients, significantly reduces the workload of medical staff, and is easy to use.

[0035] To make the content of this utility model easier to understand, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model.

[0036] Example 1

[0037] Combined with appendix Figure 1-3 The bottom plate 1 has symmetrical support plates 2 at both ends of its lower end face. The support plates 2 are rotatably connected to a rotating shaft. The support plates 2 have an mounting plate 3 between them. The mounting plate 3 is connected to the rotating shaft. The lower end face of the mounting plate 3 has a symmetrical electric push rod 4. The bottom end face of the bottom plate 1 has a first angle adjustment component on one side. The first angle adjustment component adjusts the angle of the rotating shaft.

[0038] The first angle adjustment component includes a bidirectional cylinder 13, a transmission rod 14, a rack 15, and a gear 16. The bidirectional cylinder 13 is disposed on the lower end face of the base plate 1. The piston rod of the bidirectional cylinder 13 is connected to the rack 15 through the transmission rod 14. The gear 16 is disposed at one end of the rotating shaft, and the rack 15 meshes with the gear 16.

[0039] Before transport, medical staff adjust the height of the electric push rod 4, which serves as the support leg, using a controller based on the actual terrain and the height of the docking equipment. When encountering stairs or slopes, the piston rod of the bidirectional cylinder 13 extends or retracts, driving the rack 15 via the transmission rod 14. The rack 15 then rotates the gear 16 it meshes with, which in turn rotates the mounting plate 3 via a shaft. The mounting plate 3 adjusts the angle of the electric push rod 4, which acts as the support leg, to keep the stretcher level. The extension / retraction range of the electric push rod 4 is 30-80 cm to meet different docking needs. The electric push rod 4 can flexibly adjust its angle within a range of ±45 degrees to ensure the stretcher remains level even on complex terrain.

[0040] Combined with appendix Figure 1 , 24. The upper end of the base plate 1 is symmetrically provided with upright plates 6. A controller is provided between the base plates 1. The upright plates 6 are hinged together with a head plate 7, a chest plate 8, a belly plate 9, and a leg plate 10. A second angle adjustment component is provided below the head plate 7, chest plate 8, belly plate 9, and leg plate 10 on the upper end of the base plate 1. The second angle adjustment component adjusts the angle of the head plate 7, chest plate 8, belly plate 9, and leg plate 10.

[0041] The second angle adjustment component includes an electric push rod 17, a transmission rod 18, a movable block 19, and a connecting block 20. The electric push rod 17 is located on the upper surface of the base plate 1. The piston rod of the electric push rod 17 is connected to the movable block 19. The connecting block 19 is located on the lower surface of the head plate 7, chest plate 8, abdominal plate 9, and leg plate 10. The transmission rod 18 is provided between the movable block 19 and the connecting block 20. The two ends of the transmission rod 18 are respectively hinged to the movable block 19 and the connecting block 20.

[0042] The bed board is divided into four sections: headboard (7), chest board (8), abdominal board (9), and legboard (10), each of which can be independently and electrically adjusted. The piston rod of the electric push rod 17 extends and retracts, driving the movable block 19 to move. The movable block 19, through the transmission rod 18, drives the connecting block 20 to move, which in turn rotates the headboard (7), chest board (8), abdominal board (9), and legboard (10). The headboard (7) can be raised 0-60 degrees to facilitate breathing and eating; the chest board (8) can be adjusted between 0-30 degrees, beneficial for patients with poor cardiopulmonary function; the abdominal board (9) can be finely adjusted 0-15 degrees to relieve abdominal pressure; and the legboard (10) can be raised 0-45 degrees to promote blood circulation. Each section has a position memory function, allowing for one-button restoration of commonly used positions.

[0043] Combined with appendix Figure 1 , 2 5. A docking component is provided between the upper end face of the base plate 1 and the vertical plate 6. The docking component includes an electric push rod 27 and a connecting plate 28. The connecting plate 28 is slidably connected to the vertical plate 6. The electric push rod 27 is provided on the upper end face of the base plate 1. The piston rod of the electric push rod 27 is connected to the connecting plate 28.

[0044] The upper surface of the connecting plate 28 is inclined, and ball bearings are evenly rolled on the upper surface of the connecting plate 28.

[0045] The stretcher bed is equipped with a docking component, and the connecting plate 28, which makes up the docking component, is made of smooth medical-grade stainless steel. During docking, the connecting plate 28 can extend 30-50 cm under the action of the electric push rod 27, making it fit snugly against the bed. The upper surface of the connecting plate 28 is beveled and has evenly rolling ball bearings to reduce transfer resistance. Additionally, foldable auxiliary handrails can be installed at the head and tail of the stretcher bed for easy handling and securing by medical staff.

[0046] Combined with appendix Figure 1-2The piston rod of the electric push rod 4 is equipped with a self-locking universal wheel 5, and the lower end face of the base plate 1 is equipped with a stair climbing component, which enables the stretcher bed to automatically climb stairs with the cooperation of the track.

[0047] The stair-climbing component includes a belt groove 21, a connecting shaft 22, and a motor 23. The belt groove 21 is symmetrically arranged below the base plate 1. The belt groove 21 is connected to the base plate 1 through a connecting rod. The two ends of the belt groove 21 are rotatably connected to pulleys.

[0048] The piston rod of the electric push rod 4 is equipped with self-locking universal wheels 5 for easy pushing on flat ground. A stair-climbing track is laid on the stairs; the track is made of lightweight, high-strength aluminum alloy and can be quickly installed on the stairs. The belt groove 21 is placed within the track. The motor 23 drives the sprocket 26 to rotate, which in turn drives the sprocket 25 via a chain. The sprocket 25, through the connecting shaft 22, drives the pulley to rotate, which in turn drives the track 24. The track 24 moves within the track, allowing the stretcher to ascend and descend the stairs at a stable speed. By controlling the speed of the motor 23, the stair-climbing speed of the stretcher can be adjusted.
