Description
Technical Field
[0001] This utility model relates to a medical hyperbaric oxygen chamber seat adjustment device, belonging to the field of medical equipment technology. Background Technology
[0002] A medical hyperbaric oxygen chamber is a specialized medical device used for oxygen therapy in a 1.5-3.0 ATA high-pressure environment. It treats various diseases by inhaling pure or high-concentration oxygen. During treatment, patients need to enter the sealed chamber and sit comfortably in a seat.
[0003] In the process of realizing the technical solution of this application, the inventors discovered that the prior art has at least the following technical problems: Inconvenient entry and exit, and unfriendly to those with mobility impairments: Traditional hyperbaric oxygen chamber seats are mostly fixed or manually adjustable. The entrance to a hyperbaric oxygen chamber is usually high and the space is small. For elderly patients, those recovering from surgery, or those with mobility impairments, it is very difficult to enter the chamber independently and sit down. They often need the assistance of medical staff, which not only increases the workload of medical staff but also brings inconvenience and potential safety risks to patients.
[0004] Existing adjustment mechanisms have limited travel and complex structures: Some existing electrically adjustable seats may use lead screw drives to achieve positioning accuracy. However, lead screw drives face problems such as excessively long lead screws leading to vibration and sagging, as well as high manufacturing costs, when a longer travel is required (e.g., moving the seat from deep within the cabin to the doorway). This makes it difficult to achieve the function of completely moving the seat to the entrance for easy "sliding" into place by the patient. In addition, its transmission structure may occupy a lot of space in a compact cabin and requires high installation precision. Utility Model Content
[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a medical hyperbaric oxygen chamber seat adjustment device with a simple and reliable structure, a long adjustment stroke, and the ability to move the seat to the door of the chamber to greatly facilitate patients' entry and exit.
[0006] The medical hyperbaric oxygen chamber seat adjustment device of this utility model includes: The warehouse body is equipped with entrances for personnel to enter and exit; Seats, which are movable and located inside the cabin; A guiding mechanism is used to guide the seat to move along a preset path. The guiding mechanism includes a guide member arranged along the seat movement path and a sliding member that slides with the guide member. The seat is connected to the sliding member. A drive mechanism for moving the seat, comprising: At least two sprockets are located inside the compartment; A drive component, which is connected to a transmission of one of at least two sprockets; A chain in the form of a closed loop is wound around at least two sprockets; The locking mechanism secures the seat to the chain links.
[0007] Furthermore, the guide extends to the vicinity of the entrance so that the seat can be moved to the entrance.
[0008] Furthermore, the guiding mechanism includes at least two parallel guide members, and the seat is connected to the guide members respectively through at least two sliding members.
[0009] Furthermore, the drive mechanism includes at least two sets of sprockets and chains arranged in parallel.
[0010] Furthermore, the locking element includes: Positioning plate, located on one side of the chain; At least two movable plates are located on the other side of the chain and are inserted into the positioning plate; Screws pass through the gaps between the links of the positioning plate and the chain, and are threaded into the movable plate to clamp and fix the positioning plate and the movable plate onto the chain. The seats are connected to the movable panel.
[0011] Furthermore, a connecting plate is provided at the lower end of the seat, and the connecting plate has a mounting groove for inserting a movable plate.
[0012] Furthermore, the sliding end of the mounting groove is provided with a fixing element to prevent the movable plate from falling out of the mounting groove.
[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a chain drive mechanism to achieve an ultra-long travel distance, enabling the seat to be completely moved from inside the chamber to the entrance. Patients (especially those with mobility impairments) do not need to step inside the chamber; they can simply "slide" smoothly to their seats from outside, greatly reducing the difficulty of patients entering and exiting the hyperbaric oxygen chamber, improving ease of use and safety, and also alleviating the burden on medical staff.
[0014] Compared to lead screw drives, which are complex, costly, and prone to vibration in long-stroke applications, the chain drive structure used in this invention is simpler and more compact. Both the chain and sprocket are standardized components, resulting in low procurement and maintenance costs. The transmission is reliable and not easily damaged, making it ideal for applications with high reliability requirements, such as hyperbaric oxygen chambers. Attached Figure Description

[0017] Example 1 like Figures 1-6 As shown, the medical hyperbaric oxygen chamber seat adjustment device of this utility model includes: The warehouse body 1 has an entrance 11 for personnel to enter and exit; Seat 2 is movably disposed inside the cabin 1; The guide mechanism 3 is used to guide the seat 2 to move along a preset path. The guide mechanism 3 includes a guide member 32 arranged along the moving path of the seat 2, and a sliding member 31 that slides with the guide member 32. The seat 2 is connected to the sliding member 31. Drive mechanism 4, used to drive seat 2 to move, drive mechanism 4 includes: At least two sprockets 42 are located inside the housing 1; Drive component 43 is connected in transmission to one of at least two sprockets 42; A chain 41 in the form of a closed loop is wound around at least two sprockets 42; Locking element 5 secures seat 2 to the link of chain 41.
[0018] The guide mechanism 3 provides stable guidance for the movement of the seat 2. In this embodiment, the guide mechanism 3 is preferably two parallel guide members 32 (e.g., linear guide rails) arranged on the floor. The lower end of the seat 2 is slidably connected to these two guide members 32 via at least two sliders 31 (e.g., block sliders). This dual-rail design ensures the stability and anti-tipping ability of the seat 2 during movement. Crucially, the length of the guide members 32 extends from the depth of the compartment 1 to near the entrance 11, providing complete path support for the long-distance movement of the seat 2.
[0019] The drive mechanism 4 is the power source for moving the seat 2. It includes two sets of chain drive systems arranged in parallel to provide stronger traction and stability. Each set of chain drive systems consists of at least two sprockets 42 arranged front and rear and a chain 41 wound around them in a closed loop. One of the sprockets 42 is connected to the drive unit 43 (such as a geared motor).
[0020] The connection between seat 2 and chain 41 is achieved through a specially designed locking element 5. For example... Figure 4 and Figure 6 As shown, the locking component 5 includes a positioning plate 51 located above the chain 41 and two movable plates 52 that can be inserted into both sides of the positioning plate 51. During installation, the positioning plate 51 and the movable plates 52 are placed on the upper and lower sides of the chain 41, respectively. Then, screws 53 are passed through the gaps between the positioning plate 51 and the chain links of the chain 41 and tightened onto the movable plates 52. In this way, the entire locking component 5 is firmly "clamped" onto the chain 41.
[0021] The lower end of the seat 2 is provided with a connecting plate 21, which has a mounting groove 22. The upper end of the movable plate 52 can be directly inserted into the mounting groove 22. To prevent accidental dislodgement, a fixing member 23 (such as a fixing plate) is also provided at the sliding end of the mounting groove 22 to ensure the reliability of the connection.
[0022] With the above structure, when the drive unit 43 is working, the chain 41 moves, and through the locking unit 5, it drives the seat 2 to move back and forth precisely and smoothly along the guide 32, thereby realizing convenient switching between the cabin door and the treatment position inside the cabin.
[0023] The length of the guide 32 extends to the vicinity of the inlet 11 so that the seat 2 can be moved to the inlet 11.
[0024] The guiding mechanism 3 includes at least two parallel guide members 32, and the seat 2 is connected to the guide members 32 by at least two sliding members 31 respectively.
[0025] The drive mechanism 4 includes at least two sets of parallel-arranged sprockets 42 and chains 41. Compared to the screw drive, which is complex, costly, and prone to vibration in long-stroke applications, the chain drive structure is simpler and more compact. Both the chain and sprockets are standardized components, resulting in low procurement and maintenance costs, reliable transmission, and resistance to damage. This makes it ideal for applications with high reliability requirements, such as hyperbaric oxygen chambers.
[0026] Locking component 5 includes: Positioning plate 51 is located on one side of chain 41; At least two movable plates 52 are located on the other side of the chain 41 and are inserted into the positioning plate 51. Screw 53 passes through the gap between the links of positioning plate 51 and chain 41 and is threaded to movable plate 52 to clamp and fix positioning plate 51 and movable plate 52 onto chain 41. Seat 2 is connected to movable plate 52.
[0027] The lower end of the seat 2 is provided with a connecting plate 21, and the connecting plate 21 is provided with a mounting groove 22 for the movable plate 52 to be inserted.
[0028] The sliding end of the mounting groove 22 is provided with a fixing member 23 to prevent the movable plate 52 from falling out of the mounting groove 22.
[0029] Working process or working principle: Patient preparation: When a patient needs to enter the hyperbaric oxygen chamber, medical staff activate the drive unit 43, such as a motor. The drive unit 43 drives a sprocket 42 on one side to rotate via a transmission mechanism.
[0030] Seat removal: The rotation of sprocket 42 drives the chain 41, which is in a closed loop, to move. Since the seat 2 is fixed to the chain 41 by the locking member 5, the movement of the chain 41 will cause the seat 2 to move along the guide member 32 towards the entrance 11. Guided by the sliding member 31, the seat 2 moves smoothly to the entrance 11, making it convenient for the patient to sit down outside the cabin.
[0031] Seat placement: After the patient is seated, the medical staff activates the drive unit 43 in the opposite direction. The chain 41 moves in the opposite direction, thereby smoothly bringing the seat 2 into the preset treatment position inside the chamber 1.
[0032] Treatment and Removal: After treatment, repeat step 2 to move seat 2 to entrance 11 for the patient's safe exit. The entire process features electric and long-distance precise control of the seat position, making operation simple and convenient.
[0033] The descriptions of the orientation and relative positional relationships of the structure in this utility model, such as descriptions of front, back, left, right, up, and down, do not constitute a limitation on this utility model, but are merely for the convenience of description.
