Detailed Implementation

[0026] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0027] Example 1

[0028] A hand restraint device for intravenous infusion in psychiatric patients, such as Figures 1-3 As shown, it includes a first placement tray 1, a first fixing rod 2, a mounting plate 3, a guide rod 4, a clamping component 5, and a tightening assembly 6. Four first fixing rods 2 are welded longitudinally and evenly at the bottom of the first placement tray 1. The mounting plate 3 is slidably connected to the lower part of the first fixing rod 2. The guide rod 4 is symmetrically rotated and connected to the mounting plate 3. The clamping component 5 is fixedly connected to the guide rod 4. The tightening assembly 6 is provided on the guide rod 4 for tightening the clamping component 5.

[0029] like Figure 1 and Figures 4-6As shown, the tightening assembly 6 includes a fixed plate 61, a sliding frame 62, and a first screw 63. The fixed plate 61 is bolted to the lower right bottom of the first placement plate 1. The sliding frame 62 is slidably connected to the guide rod 4. The guide rod 4 has a spiral groove 64. The collar portion 621 of the sliding frame 62 has a protrusion 622, which slidably engages with the spiral groove 64. The first screw 63 is rotatably connected to the mounting plate 3. The first screw 63 is rotatably connected to the fixed plate 61 and threadedly connected to the sliding frame 62. By rotating the first screw 63, the sliding frame 62 is pushed along the guide rod 4. During the movement, the sliding frame 62 causes the guide rod 4 to rotate through the protrusion 622 and the spiral groove 64, causing the clamping member 5 to close.

[0030] like Figure 1 and Figure 7 As shown, it also includes a second screw 7, which is rotatably connected to the bottom of the first placement plate 1, and the second screw 7 is threaded through the middle of the mounting plate 3. By rotating the second screw 7, the mounting plate 3 can slide up and down along the guide rod 4.

[0031] like Figure 1 and Figure 8 As shown, it also includes a restraint assembly 8, which is provided on the first placement tray 1. The restraint assembly 8 includes a first L-shaped plate 81, a second placement tray 82, and a restraint strap 83. The first L-shaped plate 81 is fixed to the lower left bottom of the first placement tray 1 by bolts. The second placement tray 82 is fixed to the first L-shaped plate 81 by bolts. The restraint strap 83 is slidably connected to the second placement tray 82. The patient's palm is placed on the restraint strap 83 and the second placement tray 82. The patient's palm and fingers can be restrained and fixed by tightening the restraint strap 83.

[0032] like Figure 1 , Figure 9 and Figure 10 As shown, it also includes a pulling component 9, which is provided on the sliding frame 62. The pulling component 9 includes a second L-shaped plate 91, a connecting plate 92, and a guide rod 93. The second L-shaped plate 91 is fixedly connected to the sliding frame 62. The guide rod 93 is longitudinally welded to the bottom of the second placement plate 82. One side of the connecting plate 92 is slidably connected to the guide rod 93. The other side of the connecting plate 92 is hinged to the second L-shaped plate 91. The restraint strap 83 is fixedly connected to the connecting plate 92. The side of the connecting plate 92 connected to the guide rod 93 is inclined downward. As the second L-shaped plate 91 moves towards the side closer to the guide rod 93, the connecting plate 92 will move downward along the guide rod 93, thereby pulling the restraint strap 83, thus achieving the effect of restraining and fixing the patient's palm and fingers.

[0033] When performing injection fixation on a mental patient, first place the patient's arm on the first placement plate 1 and the patient's fingers on the second placement plate 82. If the height of the fixation device is not suitable for the patient's height, turn the second screw 7 forward. As the second screw 7 turns, it causes the mounting plate 3 to move upward with the clamping member 5, so that the patient's forearm can be placed on the first placement plate 1. When the patient is in a comfortable position, turn the second screw 7. After the arm and fingers are properly positioned, fixation can begin. First, turn the first screw 63 forward. The protrusion 622 in the collar 621 on the sliding frame 62 slides along the spiral groove 64 on the guide rod 4, so that the sliding frame 62 begins to slide, further driving the guide rod 4 to rotate, so that the clamping members 5 close together. At the same time, as the sliding frame 62 slides to the left, it moves the second L-shaped plate 91 to the left, thereby pushing the connecting plate 92 to move downward along the guide rod 93, thereby pulling the restraint strap 83 downward, thus achieving the restraint and fixation of the arm and fingers.

[0034] Example 2

[0035] Based on Example 1, such as Figure 1 and Figure 11 As shown, it also includes a fixing component 10. The fixing component 10 is provided at the lower part of the first placement tray 1. The fixing component 10 includes a mounting frame 101 and a clamping block 102. The mounting frame 101 is symmetrically welded to the lower part of the first placement tray 1, and the clamping block 102 is symmetrically slidably connected to the lower part of the mounting frame 101.

[0036] like Figure 1 and Figure 12 As shown, it also includes a traction assembly 11, which is provided on the second L-shaped plate 91. The traction assembly 11 includes a second fixing rod 111, a pull rope 112, and a spring 113. The second fixing rod 111 is welded to the second L-shaped plate 91. The lower part of the second fixing rod 111 is fixed to the middle part of the pull rope 112. The two ends of the pull rope 112 are fixed to the clamping blocks 102 on both sides respectively. The clamping blocks 102 on both sides are jointly fixed to the spring 113. The spring 113 is placed inside the clamping blocks 102 and is used to keep the clamping blocks 102 on the front and rear sides close to each other.

[0037] When the device needs to be fixed to a chair handle or bed frame, the clamping blocks 102 are first separated and clamped to the chair handle or bed frame. Due to the elastic force of the spring 113, the clamping blocks 102 can be brought closer together and clamped to the chair handle or bed frame. When fixing the patient's hand, as the sliding frame 62 slides to the left, it pushes the second L-shaped plate 91 to move to the left, thereby pushing the second fixing rod 111 to move. The pull rope 112 on the second fixing rod 111 pulls the clamping blocks 102 together, thereby achieving further fixation of the clamping blocks 102.

[0038] Although this disclosure has been described with respect to only a limited number of embodiments, those skilled in the art who benefit from this disclosure will understand that various other embodiments can be devised without departing from the scope of the invention. Therefore, the scope of the invention should be limited only by the appended claims.
