Description

Technical Field

[0001] This utility model relates to the field of medical auxiliary equipment technology, and in particular to a small medical oxygen generator. Background Technology

[0002] In various settings such as clinical treatment, home care, and high-altitude work, a stable oxygen supply is often required to meet the respiratory needs of patients or users. Especially during the rehabilitation of patients with chronic respiratory diseases and cardiovascular diseases, continuous oxygen supply can effectively alleviate symptoms and improve quality of life. With increasing health awareness and the widespread use of home medical devices, miniaturized and portable medical oxygen generators have gradually gained widespread attention and application. Medical miniature oxygen generators, with their small size, ease of operation, and wide applicability, have become an important tool for many families and medical institutions to provide auxiliary oxygen supply to patients.

[0003] Currently, most commercially available small medical oxygen concentrators employ molecular sieve pressure swing adsorption (PSA) technology, using compressed air to separate nitrogen and oxygen, thereby obtaining a stable output of high-purity oxygen. These devices typically include a compressor, molecular sieve, oxygen storage tank, flow regulator, and control module, meeting the basic oxygen needs of both home and clinical environments. To facilitate handling and movement, some oxygen concentrators are equipped with handles or levers to improve portability. However, carrying by handles is time-consuming and laborious, while integrated levers take up space, making the use of the device somewhat inconvenient. Therefore, this paper proposes a small medical oxygen concentrator to address these issues. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a small medical oxygen concentrator, which aims to improve the problems of time-consuming and laborious handling by handles and the space-consuming integrated pull rod in the existing technology, making it more troublesome to use the equipment.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A small medical oxygen concentrator includes an oxygen concentrator body, an adjustment mechanism and a convenient mechanism provided on the side wall of the oxygen concentrator body;

[0007] The adjusting mechanism includes a sleeve and a slide rod. A fixed platform is fixedly connected to the bottom of the sleeve. The side wall of the fixed platform is fixedly connected to the rear side wall of the oxygen concentrator body. The side wall of the slide rod is slidably connected to the inside of the fixed platform. A groove is opened inside the slide rod and a sliding plate is installed inside. A locking block is fixedly connected to the side wall of the sliding plate. A spring is installed inside the groove. Holes are opened on both the upper and lower sides inside the fixed platform. A handle is fixedly connected to the top of the slide rod. A limiting plate is fixedly connected to the side wall of the slide rod and is slidably connected to the inside of the sleeve.

[0008] As a further description of the above technical solution:

[0009] The sidewall of the card block is slidably connected to the inside of the recess, and the card block is slidably connected to the inside of the groove via a sliding plate.

[0010] As a further description of the above technical solution:

[0011] One end of the spring is fixedly connected to the side wall of the slide plate, and the other end of the spring is fixedly connected to the inside of the groove.

[0012] As a further description of the above technical solution:

[0013] A reinforcing plate is fixedly connected between the sleeves, and the side wall of the reinforcing plate is fixedly connected to the rear side wall of the oxygen generator body.

[0014] As a further description of the above technical solution:

[0015] The convenient mechanism includes pulleys and handles. The handles are fixedly connected to the top of the oxygen concentrator body and multiple handles are provided. A connecting seat is fixedly connected to one side of the bottom of the oxygen concentrator body, and the pulleys are rotatably connected to both sides of the connecting seat.

[0016] As a further description of the above technical solution:

[0017] A support block is fixedly connected to the other side of the bottom of the oxygen generator body, and the pulley and the support block are on the same horizontal plane.

[0018] As a further description of the above technical solution:

[0019] Each handle has a fixed bottom with a cushioning anti-slip pad, which is made of rubber material.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, by pulling the slide rod upward with the handle, the locking block is squeezed inside the sleeve and moves into the groove, while simultaneously squeezing the spring. When the locking block aligns with the recessed hole, the spring resets, locking the locking block inside the recessed hole and fixing the position of the slide rod. This changes the length of the pull rod, making it easier for medical staff to move the equipment. When the equipment is in use, the pull rod can be shortened to avoid affecting the normal use of the equipment.

[0022] 2. In this utility model, when the equipment is placed horizontally, the pulley and the support block support the ground simultaneously. The friction between the support block and the ground can ensure the stability of the equipment and prevent the equipment from shifting during use. When the equipment is tilted and only the pulley supports the ground, it is easy to move the equipment. The handle makes it easy for multiple medical staff to move the equipment at the same time. The cushioning and anti-slip pad achieves the effects of cushioning and anti-slip, improving the stability of the equipment during use. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1-4This utility model provides an embodiment of a small medical oxygen concentrator, including an oxygen concentrator body 1. The oxygen concentrator body 1 is existing technology and will not be described in detail here. An adjustment mechanism and a convenient mechanism are provided on the side wall of the oxygen concentrator body 1. The convenient mechanism includes pulleys 14 and handles 16. Multiple handles 16 are fixedly connected to the top of the oxygen concentrator body 1 to facilitate simultaneous handling by multiple medical personnel. Each handle 16 has a fixedly connected cushioning anti-slip pad 17 made of rubber material, which provides an anti-slip effect during handling, preventing the handle 16 from slipping off the hand and providing a cushioning effect. The improved grip allows for quick movement of the oxygen concentrator. A connecting seat 13 is fixedly connected to one side of the bottom of the main body 1, with pulleys 14 rotatably connected to both sides of the connecting seat 13. By tilting the device, only pulleys 14 are in contact with the ground, enabling rapid movement. A support block 15 is fixedly connected to the other side of the bottom of the main body 1. The pulleys 14 and support block 15 are on the same horizontal plane. When both pulleys 14 and support block 15 support the ground, the friction between support block 15 and the ground ensures the stability of the device, preventing it from shifting during use. The adjustment mechanism includes a sleeve 3 and a sliding rod 4. A fixed platform 2 is fixedly connected to the bottom of the sleeve 3, serving to connect the adjustment mechanism to the main body of the oxygen concentrator. The connection between the body 1 and the fixed platform 2 is fixedly connected to the rear side wall of the oxygen concentrator body 1. The side wall of the slide rod 4 is slidably connected to the inside of the fixed platform 2. The slide rod 4 has a groove 5 and a sliding plate 6 inside. The side wall of the sliding plate 6 is fixedly connected to a locking block 7. The groove 5 has a spring 8 inside. The fixed platform 2 has recessed holes 10 on both the upper and lower sides, which match the locking blocks 7. The top of the slide rod 4 is fixedly connected to a handle 12, which can be used to pull the device. The side wall of the slide rod 4 is fixedly connected to a limiting plate 9, which is slidably connected to the inside of the sleeve 3. The limiting plate 9 prevents the slide rod 4 from being pulled out of the sleeve 3. The side wall of the locking block 7 slides. Connected inside the recess 10, the locking block 7 is slidably connected to the inside of the groove 5 via the slide plate 6. One end of the spring 8 is fixedly connected to the side wall of the slide plate 6, and the other end of the spring 8 is fixedly connected to the inside of the groove 5. A reinforcing plate 11 is fixedly connected between the sleeves 3. The side wall of the reinforcing plate 11 is fixedly connected to the rear side wall of the oxygen concentrator body 1. When the slide rod 4 is pulled upward by the handle 12 to move inside the sleeve 3, the locking block 7 will be squeezed and move into the groove 5, while squeezing the spring 8 to deform it. When the locking block 7 is aligned with the recess 10, the spring 8 will lose pressure and reset. Then, the sliding plate 6 will lock the locking block 7 inside the recess 10, fixing the position of the slide rod 4.

[0031] Working principle: When the equipment needs to be used, in order to quickly transfer the equipment, the handle 12 can be pulled upward to move the slide rod 4 upward inside the sleeve 3. During the movement, the locking block 7 will be squeezed and disengaged from the recess 10. At the same time, the sliding plate 6 will compress the spring 8 to deform it. As the slide rod 4 continues to move upward, when the limiting plate 9 is in contact with the top of the inner wall of the sleeve 3, the locking block 7 will move into the recess 10 at the top. At this time, the spring 8 will lose pressure and reset. Then, the sliding plate 6 will lock the locking block 7 into the recess 10, fixing the position of the slide rod 4. Medical staff can then pull the handle 12 to move the equipment, thereby achieving the effect of quickly transferring the equipment. When the equipment needs to be transferred between different floors, two medical staff can lift the equipment by hand using the handle 16. At this time, the cushioning anti-slip pad 17 plays a cushioning and anti-slip role, ensuring safety during the handling process.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
