Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a multi-functional transport vehicle for a hyperbaric oxygen chamber that is easy to adjust. Background Technology
[0002] Hyperbaric oxygen chambers use special devices to raise the internal pressure to a level higher than the external atmospheric pressure, typically 1.5-3 times the normal atmospheric pressure. Simultaneously, patients inhale high concentrations of pure or high-concentration oxygen, significantly increasing the dissolved oxygen level in the blood by 10-20 times. This provides sufficient oxygen to all tissues and organs. Under high pressure, oxygen can not only bind to hemoglobin for transport but also dissolve directly in the blood, being transported throughout the body via physical dissolution. It reaches ischemic and hypoxic tissues and organs more quickly, improving their oxygenation. The chamber itself is the main part of the hyperbaric oxygen chamber and is usually made of high-strength metal materials, possessing excellent sealing and pressure resistance to withstand the increased pressure inside. Depending on different usage requirements, it can be divided into single-person and multi-person hyperbaric oxygen chambers.
[0003] The entrance and exit doors of hyperbaric oxygen chambers are narrow, while the beds are wide. When treating critically ill patients, the beds cannot be pushed into the chamber and the patients need to be moved onto stretchers. However, the stretchers used in clinical practice are taller than the beds, making them inconvenient to move. Furthermore, the length, width, and tilt angle of the stretchers cannot be adjusted, which is not conducive to the use of patients of different sizes and needs. In addition, ordinary stretchers only have guardrails and no restraint devices, which reduces the effectiveness of child protection and makes it impossible to fix special patients who need restraint, thus reducing their practicality. Utility Model Content
[0004] The purpose of this utility model is to provide a multi-functional transport cart for hyperbaric oxygen chambers that is easy to adjust, in order to solve the problems mentioned in the background art, such as the fact that the flatbeds used in clinical practice are higher than the hospital beds and are not easy to move, and that the length, width and tilt angle of the flatbeds cannot be adjusted, which is not conducive to the use of patients of different sizes and needs. In addition, ordinary flatbeds only have guardrails and no restraint devices, which reduces the effectiveness of child protection and makes it impossible to fix special patients who need restraint.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional transfer vehicle for a hyperbaric oxygen chamber that is easy to adjust, comprising a first bed board, a second bed board installed at one end, a positioning block installed on the lower surface of the second bed board, two width limiting plates installed on the lower surfaces of both the first and second bed boards, an adjusting screw arranged between the two width limiting plates, a groove provided on the upper surface of the width limiting plate, and a telescopic fence installed on the inner wall of the groove of the width limiting plate, a restraining strap wrapped and fixed on the surface of the telescopic fence, a locking block installed through the side surface of the width limiting plate, a support column fixedly connected to the lower surface of the first bed board, a groove provided on the lower surface of the support column, a universal wheel connecting rod installed on the inner wall of the groove of the support column, a limiting block installed through the lower side surface of the support column, and an angle adjustment mechanism provided on the surfaces of both the first and second bed boards, which drives the positioning slider to slide horizontally by rotating the support screw, and then drives the support arm to rotate, thereby supporting the pitch support plate to rotate for angle adjustment.
[0006] Preferably, the first bed board and the second bed board are slidably connected, the positioning block is slidably connected to the second bed board, and a spring is connected between the positioning block and the second bed board. The lower surface of the first bed board is provided with positioning holes, and the positioning holes of the first bed board are arranged horizontally. The positioning holes of the first bed board are engaged with the positioning block.
[0007] By adopting the above technical solution, the structure enables flexible adjustment of the length of the transport vehicle, solving the problem that the traditional flatbed cart has a fixed length and cannot adapt to patients of different heights.
[0008] Preferably, the width limiting plates on both sides are slidably connected to the first bed plate and the second bed plate respectively. The width limiting plates are L-shaped and are threadedly connected to the adjusting screws. The threads on the outer surfaces of the two ends of the adjusting screws are in opposite directions, and the adjusting screws on both sides are rotatably connected to the first bed plate and the second bed plate respectively.
[0009] By adopting the above technical solution, the structure enables precise adjustment of the width of the transfer vehicle, solving the problem of narrow doors to the hyperbaric oxygen chamber and the inability to enter traditional flatcars with fixed widths, while also improving usability.
[0010] Preferably, the width limiting plate and the telescopic fence are slidably connected, and a spring is connected between the width limiting plate and the telescopic fence. The upper surface of one end of the locking block is inclined. The locking block and the width limiting plate are slidably connected, and a spring is connected between the locking block and the width limiting plate. A groove is provided on the lower side surface of the telescopic fence.
[0011] By adopting the above technical solution, the structure enhances the protection and restraint functions of the transport vehicle, solving the problem that traditional flatbed carts only have railings, lack effective restraint, and are insufficient in protecting children or special patients.
[0012] Preferably, the support column and the universal wheel link are slidably connected, and a spring is connected between the support column and the universal wheel link. The limiting block is slidably connected to the support column, and a groove is provided on the upper side surface of the universal wheel link.
[0013] By adopting the above technical solution, the structure enables flexible adjustment of the height of the transport vehicle, solving the problems of fixed height of traditional flatbeds, mismatch with the height of hospital beds, and difficulty in moving patients.
[0014] Preferably, the angle adjustment mechanism includes support screws, two of which pass through the side surfaces of the first bed board and the second bed board respectively. A positioning slider is installed on the outer surface of the support screw, and a support rotating arm is installed on the upper surface of the positioning slider. A pitch support plate is embedded in the upper surface of both the first bed board and the second bed board.
[0015] By adopting the above technical solution, the structure enables precise adjustment of the tilt angle of the transport vehicle, solving the problem that traditional flatbeds have fixed angles and cannot adapt to different body positions such as lying down and semi-sitting, thus improving patient comfort and treatment adaptability.
[0016] Preferably, the two support screws are rotatably connected to the first bed plate and the second bed plate respectively, the support screws are threadedly connected to the positioning sliders, and the two positioning sliders are slidably connected to the first bed plate and the second bed plate respectively. The support rotating arm is rotatably connected to the positioning sliders and the pitch support plate respectively, and the two pitch support plates are rotatably connected to the first bed plate and the second bed plate respectively.
[0017] Using the above technical solution, when the support screw rotates, the positioning slider slides horizontally through the threaded transmission, which in turn pushes the support arm to rotate, and finally supports the pitch support plate to achieve angle adjustment, which can precisely control the tilt angle of the patient's back or legs.
[0018] Compared with the prior art, the beneficial effects of this utility model are: the easily adjustable multi-functional transfer vehicle for hyperbaric oxygen chambers:
[0019] 1. This device effectively solves the problem of insufficient adaptability of traditional flatbeds through a flexible size adjustment mechanism.

It can adapt to patients of different heights and body types and the narrow doors of hyperbaric oxygen chambers, improving the compatibility of use scenarios.
[0020] 2. This device features dual height and angle adjustment functions, significantly optimizing patient transport and user experience. The height adjustment is achieved through the sliding cooperation between the support column and the universal wheel linkage to precisely match the height of the hospital bed, reducing the risk of handling. The angle adjustment mechanism drives the pitch support plate to rotate through components such as the support screw, allowing independent adjustment of the patient's back and leg angles to meet treatment and comfort needs.
[0021] 3. The protective and restraint design enhances the safety of transport. The telescopic fence, together with the locking block, can be quickly raised, lowered and locked to prevent patients from falling. The surface restraint straps can fix special patients, solving the problem of insufficient protection of traditional stretchers, especially improving the protection effect for children and agitated patients.
