Then the needle tube is inserted into the interior of the plug-in slot, and the needle is inserted into the slot hole of the covering block at the bottom of the positioning ring. The needle enters the patient's wrist blood vessel through the slot hole at the bottom of the positioning tube for injection. By setting up this mechanism, the patient's wrist can be positioned at a more suitable injection position, thereby improving the patient's rehabilitation efficiency.

[0020] 4. The present invention is provided with a fixing mechanism. When the patient is injected, the hand is placed on the top of the contact pad, and the vibration generated will be transmitted into the buffer film through the patient's hand, driving the buffer film to expand and contract on the inner wall of the contact pad.

The sliding groove on the surface of the pushing block 601 is slidably connected to the surface of the connecting rod 2. A pad 602 is fixedly connected to the top of the pushing block 601. A compression block 603 is slidably connected to the top slot of the pad 602. Pushing rings 604 are fixedly connected to both sides of the pushing block 601. Covering arms 605 are rotatably connected to both sides of the inner wall of the pad 602 through a rotating shaft. One end of the pushing ring 604 away from the pushing block 601 is fixedly connected to the surface of the covering arm 605. The patient first places his arm on the top of the pad 602, and squeezes the top of the compression block 603 through his arm, thereby driving the compression block 603 to slide toward the top slot of the pad 602. When the compression block 603 expands and contracts inward, air pressure is generated and injected into the internal air groove of the pushing block 601.

[0025] The covering assembly 606 includes a covering clamp 6061 fixedly connected to the inner wall of the covering arm 605, the inner wall of the covering clamp 6061 is fixedly connected to a contact wheel 6062, the surface of the covering clamp 6061 is fixedly connected to a blowing ring 6063, and both sides of the inner wall of the blowing ring 6063 are rotatably connected to pressing rings 6064 via a rotating shaft. When the covering arm 605 is rotated to the surface of the patient's arm, the covering clamp 6061 contacts the surface of the patient's arm, and by squeezing the contact wheel 6062 on the inner wall of the covering clamp 6061, the pressing block inside the contact wheel 6062 is extended and retracted inward, and the surface of the patient's arm is clamped and fixed by multiple pressing blocks inside the contact wheel 6062.

[0026] A pressing block is installed on the inner wall of the contact wheel 6062, and the inner wall of the contact wheel 6062 is connected with the interior of the blowing ring 6063. When the multiple pressing blocks inside the contact wheel 6062 expand and contract inward, the air pressure membrane inside it will be compressed, thereby injecting the compressed gas inside it into the blowing ring 6063, and the compressed gas is ejected outward from the inside of the blowing ring 6063, thereby causing the pressing ring 6064 to rotate. When the pressing ring 6064 rotates to the surface of the patient's arm, the patient's arm is adsorbed and fixed by the surface of the pressing ring 6064, thereby strengthening the fixation of the patient's arm and avoiding the injection efficiency being reduced due to arm tremors during injections.

[0027] The pushing ring 604 has a telescopic function. A cavity is opened inside the pushing ring 604. When the pushing ring 604 is telescoped outward, it will push the covering arm 605. The air pressure is introduced into the pushing ring 604 through the air groove inside the pushing block 601. The air pressure is injected into the pushing ring 604 to drive it to expand and contract outward. The pushing ring 604 that is telescoped outward pushes the covering arm 605, driving the covering arm 605 to rotate inward on the inner wall of the pad 602.

The patient's arm will come into contact with the inner wall of the covering ring 7071. When the patient's arm is squeezed by the contact clamp 7073, the contact clamp 7073 will slide and retract toward the inner wall of the compression chamber 7072. When the contact clamp 7073 retracts inward, it will compress the compression rod 7074. When the compression rod 7074 retracts inward, air pressure will be generated and sprayed into the inside of the connecting frame 701.

[0029] The compression assembly 707 includes a covering ring 7071 fixedly connected to the bottom of the connecting frame 701, the inner wall of the covering ring 7071 is fixedly connected to a compression chamber 7072, the inner wall of the compression chamber 7072 is slidably connected to a contact clamp 7073, the bottom of the inner wall of the contact clamp 7073 is fixedly connected to a compression rod 7074, one end of the compression rod 7074 is fixedly connected to the top of the inner wall of the compression chamber 7072, and the disinfectant flowing out will be sprayed on the surface of the patient's arm for disinfection. Only after the contact clamp 7073 is fully retracted inwardly into the compression chamber 7072 will it drive the disinfectant to be sprayed out from the inside of the spray plate 706. At this time, multiple contact clamps 7073 are fixed in the compression chamber 7072 to clamp the patient's arm. By setting this mechanism, the surface of the patient's arm can be automatically positioned for disinfection, thereby facilitating automatic disinfection of the patient's wrist.

[0030] A spray cavity is provided inside the spray block 705, and five spray pipes are fixedly connected to the bottom of the inner wall of the spray disk 706. The interior of the spray disk 706 is connected to the spray block 705.

[0031] Disinfectant is injected into the storage tank 702, and a connecting cavity is opened inside the telescopic cavity 703. The interior of the storage tank 702 is connected with the interior of the telescopic cavity 703, and the interior of the storage tank 702 is connected with the interior of the telescopic cavity 703. When air pressure is injected into the telescopic cavity 703 through the interior of the connecting frame 701, the disinfectant inside the telescopic cavity 703 is compressed and pushed, so that the disinfectant is injected into the interior of the spray block 705 through the compression tube 704.

[0032] Example 3: Based on Example 2, continue to refer to Figure 7-Figure 8 The fixing mechanism 8 includes a pushing tube 801, which is fixedly connected to the bottom of the inner wall of the auxiliary box 4, and the end of the pushing tube 801 away from the auxiliary box 4 is fixedly connected to a plug-in box 802, and the inner wall of the plug-in box 802 is slidably connected to a plug-in ring 803, and the bottom of the plug-in box 802 is fixedly connected to a base 804, and the bottom of the base 804 is fixedly connected to a contact pad 805, and the inner wall of the contact pad 805 is fixedly connected to a buffer film 806. When the patient's hand enters the interior of the auxiliary box 4, four fingers are inserted into the four plug-in rings 803 on the inner wall of the plug-in box 802. The patient pushes the plug-in rings 803 with four fingers, so that the plug-in rings 803 are retracted inwardly on the inner wall of the plug-in box 802, and the patient's hand is placed on the top of the buffer film 806 at this time. When the plug-in rings 803 are retracted inwardly, air pressure is generated and ejected from the inside of the plug-in box 802.

[0033] The positioning assembly 807 includes a clamping arm 8071, one end of the clamping arm 8071 is fixedly connected to the surface of the plug-in box 802, the end of the clamping arm 8071 away from the plug-in box 802 is slidably connected to a telescopic rod 8072, the end of the telescopic rod 8072 away from the clamping arm 8071 is fixedly connected to a covering block 8073, the top slot of the covering block 8073 is slidably connected to a positioning ring 8074, the inner wall of the covering block 8073 is fixedly connected to a contact ring 8075, the inner wall bottom of the contact ring 8075 is fixedly connected to a positioning tube 8076, and the gas ejected The pressure flows into the clamping arm 8071, thereby driving the telescopic rod 8072 to extend and retract outward from the inner wall of the clamping arm 8071, and the telescopic rod 8072 pushes the covering block 8073. When the covering block 8073 moves outward to the patient's wrist, the patient's arm is clamped and fixed by the contact wheel 6062, the blood in the blood vessels at the patient's arm will be tightened and gathered from the arm to the blood vessels at the wrist, causing the blood vessels at the patient's wrist to bulge outward due to the expansion of the blood, and the covering block 8073 will come into contact with the patient's wrist.

[0034] The positioning tube 8076 can be extended and retracted inwardly, and a contact sheet is installed at the bottom of the positioning tube 8076. One end of the positioning tube 8076 is connected to the inside of the positioning ring 8074 through the inner wall of the covering block 8073. The multiple blood vessels at the patient's wrist will squeeze the positioning tube 8076. The more the protrusion of the blood vessels at the wrist is, the longer the length of the one end of the positioning tube 8076 will be extended and retracted inside the contact ring 8075. One end of the positioning tube 8076 is connected to the positioning ring 8074 through the contact ring 8075 and the internal slot of the covering block 8073. The longer the positioning tube 8076 is extended inward, the higher the height of a positioning ring 8074 at the top of the covering block 8073 will slide toward the top. Therefore, based on the observation of the positioning ring 8074 with the maximum extension length, the needle tube is inserted into the interior of the plug-in slot 5, and the needle is inserted into the slot hole of the covering block 8073 at the bottom of the positioning ring 8074. The needle enters the patient's wrist blood vessel through the slot hole at the bottom of the positioning tube 8076 for injection, which can locate a more suitable injection position on the patient's wrist, thereby improving the patient's rehabilitation efficiency.
