Technical Field
[0001] This utility model relates to the field of medical assistive device technology, and in particular to a restraint chair specifically for psychiatric use. Background Technology
[0002] Restraint refers to the application of physical or mechanical equipment, materials, or tools attached to or near a patient's limbs to restrict the patient's movement or prevent the patient from approaching a certain part of the body. In clinical nursing work, some patients with mental illness may experience sudden illness during the nursing process, requiring restraint to prevent harm to the patient or even to medical staff.
[0003] In clinical practice, restraint chairs can be used to restrain patients with sudden illnesses. For example, the patent document with authorization announcement number CN 212089900U discloses a restraint chair for psychiatric nursing, which can fix and restrain the patient's arms and legs, thereby preventing the patient from causing harm to himself or medical staff when he has a sudden illness.
[0004] However, as can be seen from the attached drawings, the psychiatric restraint chair described in the aforementioned patent document has a fixed sitting posture that cannot be adjusted. Therefore, when the restraint time is long, the patient will inevitably feel uncomfortable while maintaining the same sitting posture, which may make the patient more agitated. Utility Model Content
[0005] This utility model provides a restraint chair specifically for psychiatric use. The technical problem to be solved is that it can change the patient's sitting posture during the restraint process, thereby reducing the discomfort caused by maintaining the same sitting posture during restraint.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0007] A psychiatric restraint chair includes a seat body and a restraint device. The restraint device is disposed on the seat body. The seat body includes a base, a support rod, a backrest, a seat, armrests, leg rests, and an adjustment rod. One end of the support rod and the backrest are respectively hinged to the front and rear ends of the base. Both ends of the armrests are respectively hinged to the middle of the backrest and the suspended end of the support rod. One end of the leg rest is hinged to the end of the armrest near the support rod. One end of the seat is hinged to both the backrest and the base, and the other end is hinged to the leg rest. One end of the adjustment rod is hinged to both the armrests and the support rod, and the other end is connected to the seat.
[0008] As a further improvement to the above technical solution:

Therefore, they should not be construed as limiting the scope of protection of this application.
[0020] To address the drawback of existing restraint chairs that cause discomfort to patients during prolonged restraint, the inventors, after careful analysis, discovered that the main reason for this problem is the fixed sitting posture, forcing patients to maintain the same position for extended periods. Based on this analysis, the inventors made structural improvements to the restraint chair.
[0021] like Figure 1-5 As shown, a psychiatric restraint chair according to this application includes a seat body 1 and a restraint device, which is disposed on the seat body 1. Specifically, the restraint device includes a body restraint frame 2, an arm restraint assembly 3, and a leg restraint assembly 4. The body restraint frame 2 is used to restrain the patient's body. One end of the body restraint frame 2 is hinged to the backrest 13, and the other end can be flipped up and opened or placed in front of the patient's body. The arm restraint assembly 3 is disposed on the armrest 15 and is used to restrain the patient's arms. The leg restraint assembly 4 is disposed on the leg rest 16 and is used to restrain the patient's legs.
[0022] Among them, reference Figure 1-3 The seat body 1 includes a base 11, a support rod 12, a backrest 13, a seat 14, an armrest 15, a leg rest 16, and an adjustment rod 17. One end of the support rod 12 and the backrest 13 are respectively hinged to the front and rear ends of the base 11. Both ends of the armrest 15 are respectively hinged to the middle of the backrest 13 and the suspended end of the support rod 12. One end of the leg rest 16 is hinged to the end of the armrest 15 near the support rod 12. One end of the seat 14 is simultaneously hinged to the backrest 13 and the base 11, and the other end is hinged to the leg rest 16. One end of the adjustment rod 17 is simultaneously hinged to the armrest 15 and the support rod 12, and the other end is connected to the seat 14.
[0023] Further, refer to Figure 4An adjustment groove 171 is provided at the other end of the adjustment rod 17. A screw 141 is provided on the side wall of the seat plate 14. A wing nut 142 is threaded onto the screw 141. The screw 141 is slidably disposed in the adjustment groove 171 and can be locked by the wing nut 142.
[0024] Therefore, by sliding the screw 141 to different positions within the adjustment groove 171 and locking it with the wing nut 142, the hinge angle between the backrest 13, seat 14, and leg rest 16 in the seat body 1 can be changed, thereby adjusting the patient's position. Thus, after a period of restraint, the patient's sitting position can be adjusted, avoiding the patient maintaining the same position for a long time during prolonged restraint, which would cause the patient to experience prolonged stress on the same position, resulting in soreness and numbness.
[0025] Among them, reference Figure 1-3 The body restraint frame 2 includes two spaced restraint rods 21, a pressure block 22, and a rotating column 23. The pressure block 22 and the rotating column 23 are respectively located at both ends of the restraint rods 21. The backrest 13 has a movable groove 131. The rotating column 23 is rotatably located in the movable groove 131. A locking component 5 is also provided between the rotating column 23 and the backrest 13 to lock the two.
[0026] The restraint bar 21 is a rigid bar, with one end in a U-shape connected to the rotating column 23. It can be placed in front of the patient and leaves a certain amount of space between itself and the patient's body. This allows for restraint while providing a small amount of room for movement, facilitating minor movements and reducing discomfort caused by the restraint. The pressure block 22 is cylindrical with a rubber layer on its outer surface. It can be placed above the patient's thighs to restrain them and prevent the patient from falling off the restraint chair when struggling violently.
[0027] Optionally, a flexible sleeve is fitted onto the restraint rod 21. The flexible sleeve may be made of sponge or silicone to increase comfort when in contact with the patient.
[0028] Specifically, refer to Figure 5 The locking assembly 5 includes a ratchet 51, a pawl 52, and a spring 53. The ratchet 51 is fixedly connected to the rotating column 23. The pawl 52 is located in the movable groove 131, with one end hinged to the backrest 13 and the other end snapped onto the ratchet 51. A lever 521 is also provided on one side of the pawl 52, with one end of the lever 521 extending out of the backrest 13. The spring 53 is sleeved on the lever 521, with both ends abutting against the pawl 52 and the backrest 13, respectively.
[0029] Meanwhile, the ratchet 51 is fixedly connected to the rotating column 23, and the pawl 52 is set in the movable groove 131. One end is hinged to the backrest 13, and the other end can be engaged with the ratchet 51 under the action of the spring 53. This prevents the restraint frame from flipping upwards to open, but it can rotate downwards to block the patient. The restraint rod 21 in the restraint frame can restrain the body, and the pressure block 22 can restrain the patient's thighs, thus quickly restraining and fixing the patient. When it is necessary to release the restraint on the patient's body, the pawl 52 can be rotated by the lever 521 and disengaged from the ratchet 51, so that the restraint frame can be flipped upwards to open normally.
[0030] Among them, reference Figure 1-3 The arm restraint assembly 3 includes an arm support 31 and a restraint strap 32. The arm support 31 is fixedly mounted on the upper end of the handrail 15, and an arc-shaped groove 311 is provided at the upper end of the arm support 31. The restraint strap 32 is fixedly mounted in the arc-shaped groove 311 in the middle, and the two ends can be glued together by Velcro. In use, the patient's arm can be placed in the restraint strap 32, and then the patient's arm can be quickly restrained and fixed by Velcro.
[0031] Among them, reference Figure 1-2 The leg restraint assembly 4 includes an "E"-shaped restraint member 41 and a baffle 42. The restraint member 41 is fixedly mounted on the leg support 16 and has a restraint groove 411 for engaging the legs. One end of the baffle 42 is hinged to the restraint member 41 and can block the front of the restraint groove 411. The other end can be detachably connected to the restraint member 41 via a fastener.
[0032] The baffle 42 can restrain the patient's legs within the restraint groove 411 to prevent the patient from causing injury to themselves or others due to excessive leg movements when a sudden illness occurs. At the same time, the restraint groove 411 has a certain amount of space for movement, allowing the patient's lower legs to move slightly within the restraint groove 411, thereby reducing the discomfort caused by the restraint.
[0033] Furthermore, a footrest 161 is also provided on the leg rest 16. The footrest 161 is perpendicular to the leg rest 16 and located below the leg restraint assembly 4. The footrest 161 can be used to support the feet, preventing the patient's feet from supporting the ground and preventing the restraint chair from tipping over due to violent struggle.
[0034] When in use, when a patient experiences an attack requiring restraint, the patient can be forcibly pressed onto the restraint chair, and the body restraint frame can quickly restrain and fix the patient's body. Subsequently, the arm restraint component 3 and leg restraint component 4 can be used to restrain the patient's arms and legs. If the patient's condition is not too severe, the body restraint frame alone can be used to restrain and fix the patient onto the restraint chair. Secondly, after the patient has been restrained for a period of time, by changing the connection position between the screw 141 and the adjusting rod 17, the hinge angle between the backrest 13, seat 14 and leg rest 16 in the seat body 1 can be changed, thereby adjusting the patient's sitting posture and avoiding the patient maintaining the same posture for a long time during prolonged restraint, which can cause the patient to experience soreness and numbness due to prolonged pressure on the same position.
[0035] It should be understood that all the above embodiments are exemplary and not restrictive. Various modifications or variations made by those skilled in the art to the specific embodiments described above under the concept of this utility model should be within the protection scope of this utility model.
