Description

Technical Field

[0001] This utility model relates to the field of hyperbaric oxygen therapy technology, specifically to a restraint and fixation seat suitable for agitated patients in a hyperbaric oxygen chamber. Background Technology

[0002] During hyperbaric oxygen therapy, some patients may experience restlessness due to illness, psychological factors, or other reasons. This not only affects the patient's own treatment outcome but may also threaten the normal operation of the hyperbaric oxygen chamber and the safety of other patients.

[0003] Currently, most seats used in hyperbaric oxygen chambers are ordinary seats, lacking effective restraint devices. They often only use simple straps for fixation, which cannot be flexibly adjusted according to the patient's level of agitation. Utility Model Content

[0004] The purpose of this invention is to provide a restraint and fixation seat suitable for agitated patients in hyperbaric oxygen chambers in order to solve the above problems, as detailed below.

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

[0006] This utility model provides a restraint and fixation seat suitable for agitated patients in a hyperbaric oxygen chamber, including an adjustment mechanism and a seat, wherein the seat is mounted on the adjustment mechanism and the adjustment mechanism can adjust the tilt angle of the seat;

[0007] A U-shaped plate is slidably mounted on the seat and extends through the back of the seat. A lumbar restraint belt is provided on the part of the U-shaped plate located on the front of the seat back. A pulling component is provided on the adjustment mechanism. When the seat is reclined, it can cooperate with the pulling component to pull the U-shaped plate, causing the U-shaped plate to bring the lumbar restraint belt closer to the back of the seat.

[0008] The above-mentioned restraint and fixation seat is suitable for agitated patients in hyperbaric oxygen chambers. The patient sits in the seat and is restrained by a lumbar restraint belt. If the patient has an agitation episode, the seat is tilted backward by the adjustment mechanism, so that the patient's feet are off the ground, making it inconvenient for the patient to exert force and preventing them from breaking free of the seat. When the seat tilts backward, it can work with the pulling component and U-shaped plate to tighten the lumbar restraint belt, thereby increasing the restraint force on the patient.

[0009] Preferably, the seat is equipped with two leg restraint straps, two arm restraint straps, and a chest restraint strap.

[0010] Preferably, the adjustment mechanism includes a base, a rotating shaft rotatably connected to the base, a seat fixedly connected to the rotating shaft, and an electric push rod inclinedly disposed between the seat and the base, with both ends of the electric push rod hinged to the base and the seat respectively.

[0011] Preferably, the pulling assembly includes a pneumatic rod and an arc-shaped rack. The pneumatic rod is fixed to the seat, and its movable end is fixedly connected to a U-shaped plate. The arc-shaped rack is fixed to the base. A fixing plate is fixedly connected to the seat, and a connecting shaft is rotatably connected to the fixing plate. A winding wheel and a gear are fixedly connected to the connecting shaft. A pull rope is fixedly connected between the winding wheel and the U-shaped plate, and the gear meshes with the arc-shaped rack.

[0012] Preferably, the gear oscillation trajectory matches the curvature of the arc-shaped rack.

[0013] Preferably, the seat is fixedly connected to a vertical plate for supporting the lower legs, and a leg restraint strap is provided on the vertical plate.

[0014] Preferably, the two ends of the waist restraint belt are fixedly connected to both sides of the U-shaped plate.

[0015] The beneficial effects are:

[0016] The patient is restrained to the seat by a lumbar restraint belt. If the patient becomes agitated, the seat can be tilted backward by an adjustment mechanism to lift the patient's feet off the ground, making it difficult for the patient to exert force and preventing them from breaking free of the seat. As the seat tilts backward, it works in conjunction with the traction component and U-shaped plate to tighten the lumbar restraint belt, increasing the restraint force on the patient. This allows for adaptation to patients with different levels of agitation, balancing patient comfort with effective restraint. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0026] See Figures 1-5 As shown, this utility model provides a restraint and fixation seat suitable for agitated patients in a hyperbaric oxygen chamber, including an adjustment mechanism 1 and a seat 2. The seat 2 is mounted on the adjustment mechanism 1, and the adjustment mechanism 1 can adjust the tilt angle of the seat 2.

[0027] A U-shaped plate 7 is slidably mounted on the seat 2, and the U-shaped plate 7 runs through the back of the seat 2. A lumbar restraint belt 8 is provided on the part of the U-shaped plate 7 located on the front of the back of the seat 2. A pulling component 3 is provided on the adjustment mechanism 1. When the seat 2 is reclined, it can pull the U-shaped plate 7 in conjunction with the pulling component 3, so that the U-shaped plate 7 drives the lumbar restraint belt 8 closer to the back of the seat 2.

[0028] As an optional implementation, the seat 2 is provided with two leg restraint straps 4, two arm restraint straps 5 and a chest restraint strap 6. The restraint force of the seat 2 can be further improved by the cooperation of the leg restraint straps 4, arm restraint straps 5 and chest restraint strap 6.

[0029] Leg restraint strap 4, arm restraint strap 5, chest restraint strap 6, and waist restraint strap 8 are all existing technologies. Their structure is two-section, and the two restraint straps are connected by buckles.

[0030] The adjustment mechanism 1 includes a base 9, a rotating shaft 10 rotatably connected to the base 9, a seat 2 fixedly connected to the rotating shaft 10, and an electric push rod 11 inclinedly arranged between the seat 2 and the base 9. The two ends of the electric push rod 11 are respectively hinged to the base 9 and the seat 2. When the electric push rod 11 is retracted, the seat 2 swings backward along the rotating shaft 10, thereby increasing the tilt angle of the seat 2.

[0031] The pull assembly 3 includes a pneumatic rod 12 and an arc-shaped rack 18. The pneumatic rod 12 is fixed to the seat 2, and the movable end of the pneumatic rod 12 is fixedly connected to the U-shaped plate 7. The arc-shaped rack 18 is fixed to the base 9. A fixing plate 13 is fixedly connected to the seat 2. A connecting shaft 14 is rotatably connected to the fixing plate 13. A winding wheel 15 and a gear 17 are fixedly connected to the connecting shaft 14. A pull rope 16 is fixedly connected between the winding wheel 15 and the U-shaped plate 7. The gear 17 meshes with the arc-shaped rack 18.

[0032] The oscillation trajectory of gear 17 matches the curvature of the arc-shaped rack 18;

[0033] When the gear 17 swings with the seat 2, it cooperates with the arc-shaped rack 18 to rotate the winding wheel 15. The winding wheel 15 winds up the pull rope, and the pull rope pulls the U-shaped plate 7. The U-shaped plate 7 drives the lumbar restraint belt 8 to move closer to the back of the seat 2, thereby tightening the restraint on the patient's waist.

[0034] A vertical plate for supporting the lower legs is fixedly connected to the seat 2, and the leg restraint strap 4 is set on the vertical plate. This design can further restrain the patient's lower limbs.

[0035] The two ends of the lumbar restraint belt 8 are fixedly connected to both sides of the U-shaped plate 7, and the lumbar restraint belt 8 can surround the patient's waist.

[0036] With the above structure, the patient sits on the seat 2 and is restrained on the seat 2 by the lumbar restraint belt 8. If the patient has agitation, the seat 2 is swung backward by the adjustment mechanism 1, so that the patient's feet are off the ground, making it inconvenient for the patient to exert force and avoid breaking free from the seat 2. When the seat 2 tilts backward, it can work with the pulling component 3 and the U-shaped plate 7 to tighten the lumbar restraint belt 8, thereby increasing the restraint force on the patient.

[0037] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
