Description

Technical Field

[0001] This utility model relates to the field of restraint chair design, and in particular to a restraint chair for the care of elderly mental patients. Background Technology

[0002] Restraint chairs have become important assistive devices in medical institutions, nursing homes, and other settings to ensure the safety of elderly patients with mental illnesses and to facilitate treatment and care by medical and nursing staff. They can restrict the patient's range of motion to a certain extent, prevent accidents, and provide a relatively safe environment, playing an indispensable role in the care of elderly patients with mental illnesses.

[0003] Currently available restraint chairs for elderly psychiatric patients have several problems. Some traditional restraint chairs use simple and crude methods of binding, often employing ropes or ordinary belts. This method is not only cumbersome and requires significant time and effort from caregivers, but also makes precise control of the binding force difficult. Too tight a restraint can cause poor blood circulation and skin damage, leading to pain; too loose a restraint will not provide effective control, allowing the patient to escape and causing accidents. Furthermore, existing restraint chairs are poorly designed for leg immobilization. Some chairs lack dedicated leg immobilization devices, or the leg immobilization structure does not conform well to the patient's legs, failing to adequately restrict leg movement. When the patient is agitated, leg movements may interfere with caregiving procedures or even cause the chair to tip over, endangering the patient and those around them. Moreover, traditional restraint chairs are often single-function, lacking comprehensive protection and comfort design for the patient. Prolonged use can cause discomfort, further exacerbating patient resistance and hindering the smooth progress of care. Therefore, it is urgent to develop a restraint chair for elderly mental patients that is easy to operate, reliable, comfortable, and can fully guarantee patient safety. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a restraint chair for the care of elderly mental patients, aiming to solve the problems existing in the restraint chair in terms of fixation method, leg fixation design, and functional comfort.

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

[0006] A restraint chair for elderly mental patients includes a base. Fixing strips are fixedly connected to both the left and right ends of the front side of the base. Storage slots are formed at both the left and right ends of the interior of the base. Movable slots are formed on opposite sides of the storage slots. Limiting components are installed inside the movable slots. A seat is connected to the top side of the base via a gas spring. A backrest is fixedly connected to the rear end of the top side of the seat. A motor is installed inside the backrest. The drive end of the motor passes through the front side of the backrest and is fixedly connected to a turntable. Two arc-shaped grooves are formed inside the turntable, and fixing components are installed inside the arc-shaped grooves.

[0007] Furthermore, armrests are fixedly connected to both ends of the top side of the seat, the rear side of the armrests is fixedly connected to the front side of the backrest, and a connecting frame is fixedly connected to the rear end of the top side of the armrests at both ends, with a sliding groove inside the connecting frame.

[0008] Furthermore, the fixing component includes a slide rod that is slidably connected inside the arc-shaped groove. A limiting piece is fixedly connected to the rear side of the slide rod, and a slider is fixedly connected to the front end of the slide rod. A fixing ring is fixedly connected to the front side of the slider.

[0009] Furthermore, the slider is slidably connected inside the groove.

[0010] Furthermore, the fixing component includes an inclined moving block, which is slidably connected inside the moving groove. Each of the two ends of the inclined moving block has a spring groove on its opposite side. A spring is installed inside the spring groove. One end of the spring is fixedly connected to the adjacent side of the two ends of the spring groove, and the other end is fixedly connected to the opposite side of the two ends of the moving groove.

[0012] Furthermore, a through groove is provided on the front side of the movable groove, and a connecting block is fixedly connected to the front side of the inclined movable block, with the connecting block slidably connected inside the through groove.

[0013] Furthermore, the front of the connecting block passes through the through groove and is fixedly connected with a sliding buckle.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the restraint chair uses a motor to drive a turntable to rotate, which in turn moves a sliding rod and a slider, causing two fixing rings to move towards the center, thereby quickly restraining and fixing the patient's upper body. This method is simple to operate, has a good fixing effect, and can effectively prevent elderly mental patients from getting up or breaking free due to emotional instability or other reasons, ensuring the patient's safety in the chair, reducing the supervision burden on nursing staff, and improving nursing efficiency.

[0016] 2. In this utility model, by placing the patient's ankle between the fixing strip and the limiting piece, and then inserting the fixing strip into the storage groove, the unique structural design of the inclined limiting block and the inclined moving block achieves convenient leg fixation. The inclined structure facilitates operation during insertion, while the planar structure reliably limits the movement after insertion, ensuring that the patient's leg is stably fixed, further enhancing the patient's stability in the chair and preventing their legs from moving erratically, affecting care, or causing injury.

[0024] 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.

[0025] Reference Figure 1-3 This utility model provides an embodiment of a restraint chair for the care of elderly mental patients, comprising a base 15, with fixing strips 4 fixedly connected to both the left and right ends of the front side of the base 15. Storage slots are provided at both the left and right ends of the interior of the base 15, and movable slots are provided on opposite sides of the storage slots. A sliding rod 18 is installed inside the movable slot. A seat 5 is connected to the top side of the base 15 via a gas spring 14. A backrest 12 is fixedly connected to the rear end of the top side of the seat 5. A motor 17 is installed inside the backrest 12. The drive end of the motor 17 passes through the front side of the backrest 12 and is fixedly connected to a turntable 10. The disc 10 has two arc-shaped grooves 13 inside, and inclined moving blocks 19 are set inside the arc-shaped grooves 13. The left and right ends of the top side of the seat 5 are fixedly connected to the armrests 6. The rear side of the armrests 6 is fixedly connected to the front side of the backrest 12. The rear ends of the top sides of the armrests 6 are fixedly connected to the connecting frame 8. The connecting frame 8 has a sliding groove 11 inside. The sliding rod 18 is slidably connected inside the arc-shaped groove 13. The rear side of the sliding rod 18 is fixedly connected to the limiting piece 16. The front end of the sliding rod 18 is fixedly connected to the slider 9. The front side of the slider 9 is fixedly connected to the fixing ring 7. The slider 9 is slidably connected inside the sliding groove 11.

[0026] Specifically, when using this restraint chair for elderly mental patients, first guide the elderly patient to sit steadily on the top side of the seat 5. After the patient is seated, start the motor 17. After the motor 17 is turned on, it drives the turntable 10 to rotate, and the turntable 10 drives the slide rod 18 to move synchronously. Since the slider 9 is fixedly connected to the slide rod 18 and the slider 9 can slide within the slide groove 11, the movement of the slide rod 18 will drive the slider 9, thereby causing the two fixing rings 7 to gradually move towards the middle, restraining the patient's body from both sides and confining the patient to the seat. At the same time, after the two fixing rings 7 contact, they will not completely fix the patient, thereby improving the patient's comfort and preventing further emotional instability.

[0027] Reference Figure 1 , Figure 4 and Figure 5The inclined moving block 19 is slidably connected inside the moving groove. Spring grooves are provided on the opposite sides of the inclined moving blocks 19 at both ends. Spring 1 is provided inside the spring groove. One end of spring 1 is fixedly connected to the side of the spring groove at both ends, and the other end is fixedly connected to the side of the moving groove at both ends. Multiple inclined limiting blocks 3 are fixedly connected to the side of the fixing strip 4 at both ends. A through groove is provided on the front side of the moving groove. A connecting block 20 is fixedly connected to the front side of the inclined moving block 19. The connecting block 20 is slidably connected inside the through groove. The front of the connecting block 20 passes through the through groove and is fixedly connected to a sliding buckle 2.

[0028] Specifically, after securing the upper body, the patient's legs are then secured. The patient's ankle is carefully placed between the securing strip 4 and the limiting plate 16 to prepare for subsequent leg securing. Then, one end of the securing strip 4 is slowly inserted into the receiving slot. During the insertion of the securing strip 4, because the surfaces of the inclined limiting block 3 and the inclined moving block 19 are both designed with an inclined structure, the inclined moving block 19 does not obstruct the insertion of the securing strip 4 in the initial stage. Instead, as the securing strip 4 is inserted, the inclined limiting block 3 gradually pushes the inclined moving block 19 into the moving slot, during which the inclined moving block 19 compresses the spring 1. When the inclined limiting block 3 moves past the inclined moving block 19, the previously compressed spring 1 rebounds due to its elasticity, thereby causing the inclined moving block 19 to return to its original position. At this time, the contact surface between the inclined plane moving block 19 and the inclined plane limiting block 3 becomes a plane. This structural change enables the inclined plane moving block 19 to limit the inclined plane limiting block 3 and the fixing strip 4, thereby achieving stable fixation of the patient's legs and ensuring the safety and stability of elderly mental patients in the chair.

[0029] Working principle: In use, first place the patient on the top side of the seat 5, then start the motor 17 to drive the turntable 10 to rotate, which in turn moves the slide rod 18. Since the slider 9 is fixedly connected to the slide rod 18, and the slider 9 is slidably connected inside the slide groove 11, it can drive the two fixing rings 7 to move towards the middle. The two fixing rings 7 then restrain and fix the patient. After the two fixing rings 7 move to the middle, they will not completely fix the patient, leaving some room for the patient to move, thus ensuring the patient's blood flow and comfort. Then, place the patient's ankle between the fixing strip 4 and the limiting piece 16, and then insert one end of the fixing strip 4 into the storage groove to restrain the patient. The patient's legs are secured. When the fixing strip 4 is inserted into the storage slot, the contact surfaces of the inclined limiting block 3 and the inclined moving block 19 are both inclined. Therefore, when the fixing strip 4 is inserted, the inclined moving block 19 will not limit the fixing strip 4, but will be pushed into the moving slot by the inclined limiting block 3 and compress the spring 1. After the inclined limiting block 3 moves past the inclined moving block 19, the spring 1 will rebound and drive the inclined moving block 19 to reset. The contact surface between the inclined moving block 19 and the inclined limiting block 3 becomes flat. Therefore, the inclined moving block 19 will limit the inclined limiting block 3 and the fixing strip 4, thereby securing the patient's legs. Moreover, the fixing strip 4 is made of rubber, which is not likely to cause damage to the patient's ankle.

[0030] 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.
