Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a stool cover for a hyperbaric oxygen chamber. Background Technology

[0002] Hyperbaric oxygen therapy is widely used as an adjunct treatment for diseases such as cerebral infarction, traumatic brain injury, and carbon monoxide poisoning. Patients typically need to sit and receive oxygen in a hyperbaric oxygen chamber for 60 to 100 minutes continuously. Most existing hyperbaric oxygen chambers are equipped with simple metal chairs or folding reclining chairs, with ordinary cushions and backrests added to improve comfort. Since most patients are elderly or have severe conditions, with weakened muscle strength and poor control, they are prone to sliding forward, semi-reclining, or tilting during prolonged sitting, which affects treatment effectiveness and increases the risk of falls and collisions. Furthermore, the enclosed space of the chamber requires high standards of equipment cleaning and disinfection, and the chair cushions need to be frequently removed, washed, and replaced.

[0003] To prevent patients from becoming unstable while seated in the hyperbaric oxygen chamber, some manufacturers have added simple lumbar or chest straps to the chair to restrain the patient's torso. Other solutions involve non-removable seat and back cushions with securing straps sewn onto the outside of the cushions to the chair frame, providing some restraint and anti-slip properties. However, existing structures often use single-point or two-point restraint, with the restraint straps directly sewn to the fabric cover or cushions. This results in unclear stress paths, making it prone to tearing of the fabric cover or displacement of the cushions. Furthermore, the cushions are usually fixed to the chair frame, making disassembly and replacement cumbersome and hindering frequent cleaning and disinfection. While some chairs are equipped with footrests, their height is uniform and their fit with the restraint structure is poor, limiting their effectiveness in preventing patients from sliding forward.

[0004] Existing hyperbaric oxygen chamber seats and their accompanying cushions suffer from the following main problems during use: First, the restraint straps are mostly separate lumbar or chest straps, lacking a systematic structural design integrated with the chair frame and cushions. This results in few restraint points and concentrated stress, making it difficult to maintain the stability of the patient's upper torso during prolonged treatment. Second, the cushions and chair are generally fixed using non-adjustable and non-quick-release methods. Replacing the cushion requires removing bolts or moving the entire chair, affecting work efficiency and hindering daily cleaning and disinfection. Third, the front edge of the seat cushion is often a simple soft pad structure, lacking coordination with the footrest and restraint straps, failing to effectively prevent the patient's body from slowly sliding forward along the seat surface. Therefore, it is necessary to provide a hyperbaric oxygen chamber seat cover that structurally facilitates the reliable fixing of the headrest, backrest, and seat cushion to the chair frame via multi-point anchoring units, while simultaneously working in conjunction with four-point restraint straps and the anti-slip front edge of the seat cushion. This would improve the patient's sitting stability within the hyperbaric oxygen chamber and facilitate the removal and cleaning of the cushion. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of the current technology by proposing a stool cover for a hyperbaric oxygen chamber.

[0006] In order to overcome the shortcomings of the existing technology, the present invention adopts the following technical solution:

[0007] A stool cover for a hyperbaric oxygen chamber includes a chair body, a stool cover fitted onto the chair body, and a restraint strap assembly disposed on the chair body;

[0008] The chair body includes a base arranged along the length of the hyperbaric oxygen chamber, a backrest panel fixed to the rear of the base and extending upward, a seat panel mounted on the backrest panel, and armrests connecting and fixing the backrest panel and the seat panel. The base supports and fixes the bottom of the seat panel. A foot pedal column is provided at the front of the base, and a left foot pedal and a right foot pedal are arranged sequentially on the foot pedal column.

[0009] The stool cover includes a headrest, a back cushion, and a seat cushion. The back of the headrest area and the back cushion area are provided with multiple anchoring units to the backrest panel, and the seat cushion area and the base are provided with multiple anchoring units.

[0010] Furthermore, the restraint strap assembly includes two shoulder straps and two waist straps. The rear ends of the two shoulder straps are respectively connected to the anchoring part on the upper part of the back pad area and extend forward across the shoulders of the occupant. The rear ends of the two waist straps are respectively connected to the anchoring parts on the left and right sides of the seat cover and extend forward. The front ends of the shoulder straps and the front ends of the waist straps are detachably fastened at the chest of the occupant by a fastening assembly, forming a four-point restraint on the upper torso of the occupant.

[0011] The front edge of the seat cushion area is provided with an anti-slip friction component to increase the friction between the rider's thigh and the front edge of the seat cushion, so as to prevent the rider from sliding along the front of the seat.

[0012] Furthermore, the anchoring unit includes an installation opening on the backrest or base, a connecting cylinder passing through the installation opening, and a locking cap threaded into the outer wall of the connecting cylinder. One end of the connecting cylinder is fixedly connected to the headrest, back cushion, and seat cushion, and the other end of the connecting cylinder passes through the installation opening and extends out to the outside of the backrest or the bottom of the base. The locking cap axially limits the connecting cylinder, so that the headrest, back cushion, and seat cushion are detachably fixed to the chair body through multiple anchoring units.

[0013] The beneficial effects achieved by this utility model are:

[0014] 1. By setting installation openings on the backrest and base, and using an anchoring unit consisting of a connecting cylinder and a locking cover, the headrest, back cushion, and seat cushion are fixed to the chair frame at multiple points. This allows the force of the cushion to be directly transferred to the backrest and base, ensuring reliable positioning and preventing displacement. At the same time, the corresponding cushion can be removed as a whole simply by unscrewing the locking cover, facilitating quick disassembly and replacement of the seat cover and improving the convenience of cleaning and maintaining the seat cover in the hyperbaric oxygen chamber.

[0015] 2. The restraint belt assembly consists of two shoulder straps and two waist belts. The rear ends of the shoulder straps are connected to the anchoring units on the upper part of the backrest area, and the rear ends of the waist belts are connected to the anchoring units on both sides of the seat area. The front ends form a four-point restraint system (up, down, left, and right) at the chest of the occupant through a fastening assembly. Together with the backrest, seat, and armrest frame of the chair, it enables the occupant's upper torso to maintain a stable sitting posture during 60-100 minutes of hyperbaric oxygen therapy, significantly reducing the risk of forward tilting, swaying, and accidental slippage, thus improving the safety of the treatment.

[0016] 3. A footrest column is set at the front of the base, and the left and right footrests are arranged at different heights to provide suitable foot support for passengers of different heights and body positions. At the same time, an anti-slip friction component is set at the front edge of the seat area, which greatly increases the friction between the front edge of the thigh and the front edge of the seat. With the cooperation of the four-point restraint, it effectively inhibits the body from slowly sliding forward along the seat surface, improves the comfort during long-term treatment, and reduces the workload of medical staff in repeatedly straightening and adjusting the body position.

It should be noted that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this invention. Other systems, methods, and / or features of this embodiment will become apparent to those skilled in the art after reviewing the following detailed description. Furthermore, the terminology used to describe positional relationships in the accompanying drawings is for illustrative purposes only and should not be construed as limiting the scope of this patent. Those skilled in the art can understand the specific meaning of the above terms according to the specific circumstances.

[0022] Example 1: Combined with Appendix Figure 1 and attached Figure 2 This embodiment constructs a stool cover for a hyperbaric oxygen chamber, including a chair body, a stool cover fitted onto the chair body, and a restraint strap assembly disposed on the chair body;

[0023] The chair body includes a base arranged along the length of the hyperbaric oxygen chamber, a backrest panel fixed to the rear of the base and extending upward, a seat panel mounted on the backrest panel, and armrests connecting and fixing the backrest panel and the seat panel. The base supports and fixes the bottom of the seat panel. A foot pedal column is provided at the front of the base, and a left foot pedal and a right foot pedal are arranged sequentially on the foot pedal column.

[0024] The stool cover includes a headrest, a back cushion, and a seat cushion. The back of the headrest area and the back cushion area are provided with multiple anchoring units to the backrest panel, and the seat cushion area and the base are provided with multiple anchoring units.

[0025] In practical implementation, the base can be a rectangular support frame welded from square or round steel pipes, with a mounting plate welded or bolted to its lower side for fixed connection to the bottom of the hyperbaric oxygen chamber via expansion bolts or floor rails. The backrest can be a single piece of metal plate, with its lower end welded or bolted to the rear of the base, and its upper end forming the headrest area. The seat can consist of a metal seat frame and a support plate, with a cushion laid on the support plate. The seat frame is bolted to the lower part of the backrest and the armrests on both sides. The armrests are made of bent pipes or bent profiles, with their front ends connected to the seat frame and their rear ends connected to the sides of the backrest, providing support for the occupant's upper limbs and enhancing the overall rigidity of the chair. The footrest upright is fixed vertically to the center of the front of the base, with the left and right footrests welded or bolted to different heights on the footrest upright to provide different levels of support for the occupant's feet.

[0026] The headrest, back cushion, and seat cushion in the stool cover all adopt an internal filling core and an external removable cloth cover structure. On the back of the headrest area and back cushion area, multiple anchoring units are pre-set on the side near the backrest panel, corresponding to the position of the backrest panel. On the bottom surface of the seat cushion area, multiple anchoring units are also pre-set on the side in contact with the base, so that they can be matched with the anchoring positions on the backrest panel and the base respectively during installation to achieve the positioning and fixation of the headrest, back cushion, and seat cushion relative to the chair body.

[0027] The restraint strap assembly includes two shoulder straps and two waist straps. The rear ends of the two shoulder straps are respectively connected to the anchoring part on the upper part of the back pad area and extend forward across the shoulders of the rider. The rear ends of the two waist straps are respectively connected to the anchoring parts on the left and right sides of the seat cover and extend forward. The front ends of the shoulder straps and waist straps are detachably fastened at the rider's chest by a fastening assembly, forming a four-point restraint on the rider's upper torso from top to bottom and left to right.

[0028] The front edge of the seat cushion area is provided with an anti-slip friction component to increase the friction between the rider's thigh and the front edge of the seat cushion, so as to prevent the rider from sliding along the front of the seat.

[0029] In practice, the restraint belt assembly uses webbing as the strap body for the two shoulder straps and two waist belts. The rear end of each shoulder strap is connected to the anchoring part of the corresponding anchoring unit on the upper part of the backrest area via bolts or pins, so that the tension on the shoulder strap is directly transmitted to the backrest and back panel. The rear ends of the two waist belts are connected to the anchoring parts of the anchoring units on the left and right sides of the seat cushion, respectively, so that the tension on the waist belt is transmitted to the seat cushion and base. The shoulder straps extend forward across the shoulders of the rider after being led out from the anchoring part on the upper part of the backrest area, and the waist belts extend forward from the anchoring parts on both sides of the seat cushion. At the front of the rider's chest, the front ends of the shoulder straps and waist belts are detachably fastened to each other via a fastening assembly, thereby forming a four-point restraint system (upper and lower, left and right) between the headrest, backrest, and seat cushion to fix the rider's upper torso.

[0030] The fastening assembly can adopt a multi-point safety buckle structure, with a central fastening body set in front of the chest. The front ends of the shoulder straps and waist belts are respectively equipped with plugs. After the plugs are inserted into the central fastening body, they are locked by an internal locking mechanism. Pressing the unlock button on the central fastening body can release all plugs at the same time, which is convenient for quick release of restraint in an emergency.

[0031] The front edge of the cushion area has anti-slip friction components arranged laterally on the outer fabric cover of the cushion. For example, an anti-slip strip with raised dots or transverse ribs can be sewn on, or an anti-slip rubber plate can be pasted on the support plate on the inner side of the front edge of the cushion and a corresponding window can be opened on the fabric cover so that the front edge of the occupant's thigh can directly contact the anti-slip friction components, which significantly increases the contact friction force and inhibits the occupant from slowly sliding forward during long-term treatment.

[0032] The anchoring unit includes an installation opening on the backrest or base, a connecting cylinder passing through the installation opening, and a locking cap threaded into the outer wall of the connecting cylinder. One end of the connecting cylinder is fixedly connected to the headrest, back cushion, and seat cushion, and the other end of the connecting cylinder passes through the installation opening and extends out to the outside of the backrest or the bottom of the base. The locking cap axially limits the connecting cylinder, so that the headrest, back cushion, and seat cushion are detachably fixed to the chair body through multiple anchoring units.

[0033] In practical implementation, the mounting opening can be pre-formed on the metal plate of the backrest or base by punching, drilling, or laser cutting. The center position of the mounting opening is opposite to the anchoring position of the headrest, back cushion, or seat cushion. The connecting cylinder is usually made of metal round tube or solid round rod. One end is fixedly connected to the support plate inside the headrest, back cushion, or seat cushion by welding, threaded connection, or riveting. The support plate is fixed to the back or bottom surface of the corresponding cushion core to centrally transmit the tensile force from the anchoring unit. The other end of the connecting cylinder is machined with external threads and has a stepped shoulder. During assembly, this end is inserted through the mounting opening on the backrest or base, so that the stepped shoulder abuts against the inside of the backrest or base, and the threaded section extends out of the outside of the backrest or the bottom of the base.

[0034] The locking cap is a screw cap or nut with internal threads that mate with the external threads of the connecting cylinder. After the locking cap is screwed into the connecting cylinder, it presses against the outer surface of the backrest or base, clamping the backrest or base between the stepped shoulder of the connecting cylinder and the locking cap, thereby limiting the axial movement of the connecting cylinder. Through multiple such anchoring units, the headrest, back cushion, and seat cushion are reliably fixed to the backrest and base of the chair body, respectively. When it is necessary to disassemble or replace the seat cover, simply unscrew the locking cap at the corresponding position, and the corresponding connecting cylinder, along with the headrest, back cushion, or seat cushion as a whole, can be pulled out from the installation opening, achieving quick disassembly and assembly of the cushion.

[0035] This embodiment incorporates detachable headrests, backrests, and seat cushions into the hyperbaric oxygen chamber chair base. A multi-point anchoring unit, consisting of connecting cylinders and locking covers, directly transfers the force of each cushion to the backrest and base, ensuring secure fixation while facilitating quick disassembly and replacement of the seat cover, thus improving cleaning and disinfection convenience. A four-point restraint structure, consisting of two shoulder straps and two waist straps, with the rear ends of the restraint straps connected to the chair frame via anchoring units, provides a reasonable distribution of tension, effectively maintaining upper trunk stability throughout hyperbaric oxygen therapy. A double-layered footrest and anti-slip friction components at the front edge of the seat cushion create a synergistic effect between foot support, restraint straps, and the anti-slip seat cushion, significantly reducing the risk of patients sliding forward along the seat and accidentally falling off. Compared to existing hyperbaric oxygen chamber chairs with only simple pads or single-point waist straps, this embodiment achieves significant improvements in posture stability, safety, and ease of maintenance.
