Description

Technical Field

[0001] The utility model relates to the technical field of restraint devices, in particular to a restraint chair for psychiatric use. Background Art

[0002] Restraint refers to the application of physical or mechanical devices, materials, or tools attached to or near a patient's limbs to restrict their movement or prevent them from accessing a body part. In clinical nursing, some patients with mental illness may experience sudden illness during care. Failure to promptly restrain them can result in harm to the patient themselves and even to the medical staff.

[0003] In clinical practice, restraint chairs can be used to restrain patients experiencing sudden illnesses. Commonly used restraint chairs typically use restraint belts to secure the patient to the chair, such as torso restraints for the chest and abdomen, and limb restraints for the limbs. However, if the patient struggles violently, restraints may take a long time to secure. Furthermore, to increase the effectiveness of the restraint, the belts are typically tightened, causing discomfort to the patient and potentially exacerbating the patient's agitation.

These embodiments are provided herein to make the disclosure of the present application more complete and to fully convey the concepts of the present application to those skilled in the art.

[0016] In the description of this application, it should be understood that the terms "center", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of this application.

[0017] The inventors have addressed the shortcomings of existing restraint chairs, such as the difficulty in quickly restraining patients experiencing sudden illnesses, and the discomfort caused by restraint, which can lead to increased agitation. After careful analysis, they discovered that these issues primarily arise from the use of restraint belts, which can prolong the duration of restraint if the patient struggles violently. Furthermore, to enhance the restraint effect, the belts are often tightened too tightly, causing discomfort. Based on this analysis, the inventors have developed structural improvements to the restraint chair.

[0018] like Figure 1-5 As shown, a psychiatric restraint chair in the present application includes a restraint chair body 1, a restraint frame 2 and a locking assembly 3.

[0019] refer to Figure 1-5 A seat back 11 is provided on the restraint chair body 1, one end of the restraint frame 2 is hinged to the seat back 11, and the other end can be flipped upward to open or blocked in front of the patient, and the locking assembly 3 includes a ratchet 31 and a pawl 32, the ratchet 31 is fixedly connected to the restraint frame 2, the pawl 32 is provided above the ratchet 31, and one end is hinged to the seat back 11, and the other end can be clamped on the ratchet 31.

[0020] Specifically, refer to Figure 2 The restraint frame 2 includes two spaced apart restraint rods 21, a pressure block 22, and a rotating shaft 23. The pressure block 22 and the rotating shaft 23 are respectively disposed at both ends of the restraint rod 21. A movable slot 111 is provided on the chair back 11, and the rotating shaft 23 is rotatably disposed within the movable slot 111. A ratchet 31 is fixedly connected to the rotating shaft 23, and a pawl 32 is disposed within the movable slot 111. Furthermore, a flexible sleeve 211 is provided on the restraint rod 21. The flexible sleeve 211 can be made of sponge material to increase comfort when in contact with the patient's body.

[0021] The restraint rod 21 is a hard rod, and one end of which is U-shaped and connected to the rotating shaft 23. It can block the front side of the patient and leave a certain amount of movement space between the patient and the patient's body, which is convenient for restraining the patient while leaving a small amount of movement space, facilitating the patient's body to move slightly and reduce the discomfort caused by the restraint to the patient. The outer surface of the pressure block 22 is covered with a rubber layer, which can block the upper part of the patient's thigh and restrain the patient's thigh to prevent the patient from falling from the restraint chair when struggling violently.

[0022] At the same time, reference Figure 2-4 The ratchet 31 is fixedly connected to the rotating shaft 23, and the pawl 32 is arranged in the movable groove 111 and is located above the ratchet 31. One end is hinged to the chair back 11, and the other end can be clamped on the ratchet 31 under the action of gravity, thereby preventing the restraint frame 2 from flipping upward and opening, but can rotate normally to block the patient in front of the body. The body can be restrained by the restraint rod 21 in the restraint frame 2, and the patient's thigh can be restrained by the pressure block 22, thereby quickly restraining and fixing the patient.

[0023] Further, refer to Figure 4 The pawl 32 is further provided with a toggle rod 321 and a spring 322. One end of the toggle rod 321 extends outside the seat back 11, and the spring 322 is sleeved on the toggle rod 321, with its two ends respectively contacting the pawl 32 and the seat back 11. The toggle rod 321 can be used to toggle and rotate the other end of the pawl 32 to disengage it from the ratchet 31, thereby allowing the restraint frame 2 to be flipped upward and opened after use. At the same time, to prevent one end of the pawl 32 from being unable to smoothly engage with the ratchet 31 due to gravity alone, the spring 322, which is sleeved on the toggle rod 321 and has its two ends respectively contacting the pawl 32 and the seat back 11, can exert a downward force on the pawl 32.

[0024] Further, refer to Figure 5 The chair back 11 is movably connected to the restraint chair body 1. A regular polygonal block 112 is provided on the restraint chair body 1. Adjustment slots 113 are provided on both sides of the chair back 11. A limiting slot 114 is provided above the adjusting slot 113. The limiting slot 114 is connected to the adjusting slot 113. The regular polygonal block 112 is rotatably inserted into the adjusting slot 113, or is slid upward and then clamped into the limiting slot 114, thereby limiting the rotation of the chair back 11.

[0025] During use, the chair back 11 can be slid upward to allow the regular polygonal block 112 to slide into the adjustment slot 113. At this time, the angle of the chair back 11 can be adjusted as needed. After adjusting to a comfortable angle, the chair back 11 can be slid downward to allow the regular polygonal block 112 to slide into the limiting slot 114, thereby relatively fixing the chair back 11, increasing the patient's comfort when restrained and allowing the patient to calm down more quickly. The regular polygonal block 112 can preferably be a regular octagon or a regular decagon.

[0026] refer to Figure 1-3 The front end of the restraint chair body 1 is provided with a leg rest 12 for supporting and placing the legs. The leg rest 12 is provided with a foot pedal 121 and a leg groove 122 for clamping the legs. The foot pedal 121 is arranged below the leg groove 122. The foot pedal 121 can be used for the patient to support the patient's feet, which can prevent the patient's feet from being supported on the ground and causing the restraint chair to fall over due to violent struggle.

[0027] Further, refer to Figure 1 The front end of the leg slot 122 is provided with a rotating plate 123 and a rotating buckle 124. One end of the rotating buckle 124 is located on one side of the leg slot 122 and is hinged to the leg support 12. One end of the rotating plate 123 is located on the other side of the leg slot 122 and is hinged to the leg support 12. The other end is provided with a clamping groove 125. The rotating plate 123 can be rotated to block the front end of the leg slot 122, and the rotating buckle 124 can be clamped into the clamping groove 125 to clamp and fix the rotating plate 123.

[0028] The rotating plate 123 can be used to restrain the patient's calves in the leg grooves 122 provided on the leg support 12, so as to prevent the patient from causing certain harm to himself or others due to excessive leg movements when a sudden illness occurs; and, one end of the rotating plate 123 is located on one side of the leg groove 122 and is hinged to the leg support 12, and the other end is provided with a snapping groove 125, which is "L"-shaped. The rotating buckle 124 can be clamped into the snapping groove 125 when the rotating plate 123 blocks the front end of the leg groove 122, thereby preventing the rotating plate 123 from opening, thereby restraining the patient's calves in the leg grooves 122. At the same time, there is a certain amount of movement space in the leg grooves 122, so that the patient's calves can move slightly in the leg grooves 122, thereby reducing the discomfort caused by the patient being restrained.

[0029] refer to Figure 1-3 , armrests 13 for placing arms are provided at both ends of the restraint chair body 1, and hand grooves 131 for clamping the arms are opened on the armrests 13. A restraint belt 132 is also provided on the armrests 13. One end of the restraint belt 132 is located on one side of the hand groove 131 and is fixedly connected to the armrest 13, and the other end can be wrapped around the other side of the hand groove 131 and then detachably connected to the armrest 13 through Velcro.

[0030] The restraint belt 132 can be used to restrain the patient's arms within the hand groove 131 provided on the armrest 13 to prevent the patient from causing certain harm to himself or others due to excessive arm movements when a sudden illness occurs. There is a certain amount of movement space in the hand groove 131, so that the patient's arms can move slightly in the hand groove 131, thereby reducing the discomfort caused by the patient being restrained.

[0031] During use, if a patient suddenly falls ill during the nursing process, multiple medical staff can control the patient to sit on the restraint chair and block the patient in front of the patient by rotating the restraint frame 2. The pressure block 22 set at one end of the restraint frame 2 can be pressed and blocked above the thigh, and the restraint frame 2 is limited by the ratchet 31 and the pawl 32, so that the patient's body and thigh can be quickly restrained and restricted, which can reduce the possibility of the patient's violent struggle causing harm to himself or others. After the patient's body is effectively restrained, the patient's calves and arms are placed in the leg grooves 122 and the hand grooves 131 respectively, and the rotating plate 123 is blocked and the restraint belt 132 is restrained, so that the patient's calves and arms are restrained in the leg grooves 122 and the hand grooves 131 respectively.

[0032] It should be understood that all the above embodiments are illustrative rather than restrictive, and various modifications or variations made by those skilled in the art to the above-described specific embodiments under the concept of the present invention should be within the scope of protection of the present invention.
