[0002] The psychiatric restraint chair is a specially designed medical device, mainly used in psychiatric care to restrain and protect patients who may pose a danger to themselves or others, so as to facilitate the smooth progress of treatment. For example, during infusion therapy, for patients who are mentally unable to control themselves, the use of a restraint chair can prevent the patient from removing the needle and using the needle to hurt themselves or others.

[0003] Existing restraint chairs usually have restraint straps installed on the armrests to bind the patient's wrists to prevent the patient's upper limb activities from affecting the treatment. However, infusion requires the needle to be inserted into the patient's upper limbs, usually the forearm vein. In order to enhance the restraint effect, the patient's arm usually needs to be over-bound. However, excessive binding of the restraint strap will cause poor blood flow in the patient's blood vessels, affecting the infusion effect. At the same time, mental patients are emotionally excited and struggle and shake their bodies during treatment. The contact area between the existing restraint chair and the ground is small. The restraint chair is easily caused to shake left and right during the patient's struggle, affecting the treatment effect. In severe cases, the restraint chair may even topple over, causing injury to the patient. The safety needs to be improved. When the patient shakes on the restraint chair, it will cause a large impact on the legs of the restraint chair. The legs of the existing restraint chair are usually made of metal pipes.

[0035] like Figures 1 to 4 as well as Figure 6 As shown, the support leg 3 is an inclined structure, and the apex of the outer wall of the first reinforcing rib 6 is on the same horizontal line as the apex of the outer wall of the support leg 3. The first reinforcing rib 6 can effectively increase the structural strength of 3 and reduce the possibility of its deformation and bending. By setting the first reinforcing rib, the impact of the patient on the restraint chair can be effectively dealt with, thereby extending the service life of the restraint chair. When the support frame 1 is stably placed on the ground, a triangular support structure is formed between the first reinforcing rib 6, the support leg 3 and the ground, further improving the stability of the support leg 3, and the first reinforcing rib 6 can increase the contact area between the support leg 3 and the ground, increase the friction, and avoid the two ends of the support leg 3 from sliding sideways due to force and causing the middle part to break. The middle side wall of the support leg 3 is provided with an installation slot 7, and the installation slot 7 is irregular The curved structure is adapted to the structure of the leg 3. One end of the mounting slot 7 is a closed structure, and the other end is an open structure. The support plate 2 and the leg 3 are embedded and connected, which is convenient for installation and disassembly, and convenient for maintenance and replacement of the support plate 2 and the leg 3. Stabilizing parts 15 are respectively provided at both ends of the leg 3. The stabilizing parts 15 are extended at both ends of the leg 3.

During use, if the patient sways left and right on the restraint chair, the stabilizing parts 15 can effectively reduce the probability of the restraint chair tipping over, thereby improving safety.

[0036] like Figure 3 and Figure 5As shown, one end of the arm support 5 is fixedly connected to the support leg 3, and the other end of the arm support 5 is a free end, and the arm support 5 is a curved structure adapted to the human arm structure. A positioning groove 10 is provided in the middle of the arm support 5, and the cross-section of the positioning groove 10 is a C-shaped structure adapted to the human arm structure. By setting the arm support 5, when in use, the patient's arm is placed in the positioning groove 10, and the positioning groove 10 constrains the left and right sides of the arm to prevent the patient's arm from moving left and right. The arm support 5 adapted to the human body structure lifts the patient's arm so that the patient's arm can be placed naturally to improve comfort. The front ends of the arm support 5 are respectively provided with fixed seats 1 1 and the locking seat 12, the fixing seat 11 and the locking seat 12 are all fixedly connected with the arm support 5, the locking seat 12 is provided with a locking groove 13, a fixing card plate 8 is installed on the fixing seat 11, one end of the fixing card plate 8 is rotatably connected with the fixing seat 11, and the other end of the fixing card plate 8 is tilted and inserted into the locking groove 13 and plugged with the locking seat 12. By setting the fixing card plate 8, when in use, the fixing card plate 8 is turned over to bypass the patient's wrist and plugged with the locking seat 12, thereby locking the patient's wrist, and the tail end of the arm support 5 is tilted, and the tilted part is called the elbow stop 16, and a fixing strap 9 is provided near the elbow stop 16.

[0037] The two ends of the fixing strap 9 are respectively fixedly connected to the two sides of the outer wall of the arm support 5. By setting the elbow stop 16, when in use, the patient's arm is embedded in the positioning groove 10, and the wrist is locked at the front end of the arm support 5 by the fixing clamping plate 8. At this time, the patient's arm is restricted as a whole and difficult to break free. The patient's elbow can be fixed by the fixing strap 9 to further prevent the patient's arm from breaking free. Due to the existence of the elbow stop 16, the patient's elbow is pressed against and the patient's arm is restricted from retreating, which further limits the patient's arm and effectively improves the restraint effect. The support plate 2 is an L-shaped structure as a whole, including Including the chair surface and the backrest, the chair surface is adapted to the human body buttocks structure, and the two side edges of the support plate 2 are respectively embedded in the installation slots 7 on the two groups of legs 3 and connected to the legs 3. The chair surface adapted to the human body structure can further improve the patient's comfort, and both ends of the support plate 2 are provided with outward flanges, which can increase the connection strength with the legs 3. A plurality of groups of second reinforcing ribs 14 are provided on the support plate 2. The second reinforcing ribs 14 can effectively enhance the structural strength of the support plate 2, avoid bending and breaking in the middle of the support plate 2, and thereby enable the support plate 2 to bear a higher weight and be adapted for use by different patients.

[0038] The working principle provided by the utility model is that when in use, the patient sits on the support plate 2, places the arm on the arm support 5, and inserts it into the positioning groove 10, flips the fixed card plate 8, makes the fixed card plate 8 rotate around the fixing seat 11, bypasses the patient's wrist, and inserts the other end into the locking groove 13 to lock the patient's wrist, and then binds the patient's elbow through the fixing strap 9, and the patient's elbow conflicts with the elbow stop 16. Due to the restriction of the positioning groove 10 and the elbow stop 16 on the patient's arm, and the locking of the patient's wrist by the fixed card plate 8, the activity of the patient's arm is greatly restricted. Therefore, when using the fixing strap 9 to bind the patient's elbow, the binding tightness can be appropriately reduced to avoid compressing the patient's blood vessels, resulting in poor blood flow and affecting the infusion effect.

[0039] During treatment, if the patient struggles and shakes his body left and right, the stabilizing portion 15 increases the force-bearing area on the side of the support frame 1, thereby greatly improving the stability of the restraint chair of the support frame 1. As a result, it is difficult for the patient to tilt the restraint chair by shaking himself, thus avoiding the restraint chair from tipping over due to the patient's struggle, thereby effectively improving safety.
