[0024] Refer to Figures 1-4, a syringe for anesthesia provided by the utility model: It includes a main body 1, and a fixing component 2 is installed on the outer surface of the main body 1. The fixing component 2 includes a fixing plate 201, the upper surface of the fixing plate 201 is fixedly connected to the outer surface of the main body 1, the lower surface of the fixing plate 201 is fixedly connected with a connecting band 202. The connecting band 202 has a certain elasticity and can well adapt to the finger size of medical staff. The side surface of the fixing plate 201 is fixedly connected with a fixing seat 203, the upper surface of the fixing seat 203 is fixedly connected to the outer surface of the main body 1, one end of the connecting band 202 is fixedly connected to the lower surface of the fixing seat 203. A sliding groove 204 is formed on the surface of the fixing seat 203. The sliding groove 204 enables the connecting block 206 to slide inside it, thereby driving the fixing block 207 to move. A bayonet 205 is formed on the inner bottom surface of the sliding groove 204. The bayonet 205 can limit the movement of the connecting block 206. The connecting block 206 is arranged inside the bayonet 205. The lower end of the connecting block 206 is fixedly connected with a fixing block 207. The inside of the fixing block 207 is movably connected to the outer surface of the connecting band 202. The position where the fixing block 207 slides on the connecting band 202 also moves, so that the connecting band 202 can better fit the finger size. The upper surface of the fixing block 207 is fixedly connected with a spring 208. The upper end of the spring 208 is in contact with the lower surface of the fixing seat 203. The movement of the fixing block 207 drives the spring 208 to move. When the fixing block 207 is released, the spring 208 pushes the fixing block 207 to move away from the fixing seat 203 under the action of elastic force, so that the connecting block 206 is clamped into the inside of the bayonet 205, fixing the fixing block 207, enabling the connecting band 202 to closely adhere to the finger and preventing slippage during use. The number of the fixing components 2 is two, and the two fixing components 2 are mirror-symmetrical along the central axis of the main body 1. Inside one fixing component 2, the number of the sliding grooves 204 and the connecting blocks 206 is two, and they are mirror-symmetrical along the central axis of the fixing seat 203. The number of the bayonets 205 is multiple and they are arranged at equal intervals. Place the index finger and the middle finger on the side surfaces of the two fixing plates 201 respectively, press the fixing block 207 towards the main body 1, so that the fixing block 207 drives the connecting block 206 to move towards the main body 1, disengaging from the bayonet 205 and entering the sliding groove 204. Slide the fixing block 207 towards the finger direction, so that the connecting band 202 is tightened. Then release the hand. Under the action of the spring 208, the fixing block 207 drives the connecting block 206 to be clamped into another bayonet 205, so that the finger is well fixed, thus being able to play an ideal anti-slip role during use.

[0025] Measurement scales 3 are arranged on the outer surface of the main body 1. The number of the measurement scales 3 is multiple, and the multiple measurement scales 3 are arranged at equal intervals. Through the measurement scales 3, the amount of injection can be observed, which is convenient for adjusting the amount of injection according to different personnel data.

[0026] A piston rod 4 is provided inside the main body 1, and a pressure plate 5 is fixedly connected to one end of the piston rod 4 located outside the main body 1, and a connecting plate 6 is fixedly connected to one end of the piston rod 4 located inside the main body 1, and a piston 7 is fixedly connected to the side surface of the connecting plate 6. The piston 7 is made of rubber and has a good sealing effect to prevent the anesthetic from leaking. During injection, the thumb presses the pressure plate 5 to push the piston rod 4, so that the piston 7 inside the main body 1 moves, and the anesthetic inside the main body 1 is pushed.

[0027] A water outlet 8 is fixedly connected to the side of the main body 1, and an injection needle 9 is provided on the outer surface of the water outlet 8. By inserting the injection needle 9 into the patient's body, the anesthetic can enter the patient's body through the water outlet 8 and the injection needle 9 to complete the anesthesia.

[0028] Working principle: Place the index finger and the middle finger on the side surfaces of the two fixing plates 201 respectively, press the fixing block 207 toward the main body 1, so that the fixing block 207 drives the connecting block 206 to move toward the main body 1, disengage from the bayonet 205 and enter the slide groove 204, slide the fixing block 207 toward the finger, thereby tightening the connecting belt 202, and then let go. Under the action of the spring 208, the fixing block 207 brings the connecting block 206 into another bayonet 205, so that the finger is well fixed, and the injection can be performed at this time.
