[0018] This embodiment uses the injection of a biological agent in oncology as an example. This biological agent requires subcutaneous injection, that is, injecting the drug into the fat layer. Typically, the injection is performed on the outer thigh of the patient, at a 30° angle into the subcutaneous fat layer. Therefore, the fixation component 5 in this embodiment includes a fixation ring 51 that fits onto the patient's thigh and a base 52 fixed to the fixation ring 51. The angle control unit 3 is fixed to the base 52. The fixation ring 51 includes an upper half-ring 511 and a lower half-ring 512. The free ends of the upper half-ring 511 and the lower half-ring 512 are detachably connected, specifically by Velcro or snap fasteners. The upper half-ring 511 and the lower half-ring 512 are strapped to the patient's thigh, thus fixing the fixation sleeve 1 relative to the patient's skin.

[0019] Combination Figure 1 , Figure 2 and Figure 3 The angle control unit 3 includes an arc-shaped slide rod 31, a sliding sleeve 32 sleeved on and slidingly engaged with the arc-shaped slide rod 31, and an angle bracket 33 for mounting the arc-shaped slide rod 31. The angle bracket 33 includes a first rod 331 and a second rod 332 connected at one end and forming a certain angle. The end of the first rod 331 and the second rod 332 connected is the proximal end, and the other end is the distal end. The two ends of the arc-shaped slide rod 31 are respectively fixed to the distal ends of the first rod 331 and the second rod 332. When the fixing sleeve 1 is fixed to the patient's thigh by the upper half ring 511 and the lower half ring 512, the plane containing the first rod 331 and the second rod 332 should be as perpendicular to the patient's skin surface as possible or in a horizontal state to monitor the overall condition of the syringe auxiliary device.

[0020] The first rod 331 is parallel to the base 52. The angle between the second rod 332 and the first rod 331 is greater than 60° and less than or equal to 90°. A scale is also fixed between the distal ends of the first rod 331 and the second rod 332 so that the nurse can determine the angle at which the syringe is inserted into the skin.

[0021] A first locking member 321 for locking the relative position of the sliding sleeve 32 and the arc-shaped slide rod 31 is provided on the sliding sleeve 32. In this embodiment, the first locking member 321 is a bolt. The first locking member 321 abuts against the arc-shaped slide rod 31, thereby locking the relative position between the sliding sleeve 32 and the arc-shaped slide rod 31.

[0022] The sleeve travel assembly 2 includes a straight slide rod 21 and a slider 22 that slides with the straight slide rod 21. The slider 22 is fixedly connected to the fixed sleeve 1. One end of the straight slide rod 21 is rotatably connected to the proximal end of the first rod 331, and the other end of the straight slide rod 21 is fixed to the sliding sleeve 32, allowing one end of the straight slide rod 21 to move along the arc-shaped slide rod 31 with the sliding sleeve 32, thereby adjusting the tilt angle of the fixed sleeve 1, i.e., adjusting the angle at which the syringe enters the patient's skin. The straight slide rod 21 defines the movement path of the syringe. After the nurse adjusts the angle between the syringe and the skin, the nurse only needs to push the fixed sleeve 1 to insert the needle of the syringe into the patient's skin.

[0023] The sleeve travel assembly 2 also includes a return spring 23 and a locking assembly 24 installed on the support slide near the proximal end of the first rod 331. One end of the return spring 23 abuts against the slider 22. The return spring 23 can reduce the random movement of the slider 22 on the straight slide 21, and when the drug injection is completed, the return spring 23 can make the syringe quickly withdrawn.

[0024] The locking assembly 24 includes a locking rod 241 arranged parallel to the straight slide bar 21 and a second locking member 242 for locking the locking rod 241. One end of the locking rod 241 is fixed to the side of the slider 22 facing away from the end of the first rod 331, and the other end of the locking rod 241 passes through the sliding sleeve 32 and is slidably engaged with the sliding sleeve 32. In this embodiment, the second locking member 242 is a bolt. The second locking member 242 passes through the sliding sleeve 32 and abuts against the locking rod 241. The second locking member 242 is threadedly engaged with the sliding sleeve 32.

[0025] The needle positioning unit 4 controls the length of the needle inserted into the patient's skin, ensuring accurate insertion into the fat layer. The needle positioning unit 4 includes a positioning ring 41 at the end of the needle and a telescopic member 42 fixedly connected to the positioning ring 41 at one end. The positioning ring 41 is sleeved on the needle and slidably engaged. The telescopic member 42 includes a fixing plate 421 fixed to the fixing sleeve 1 and a telescopic plate 422 inserted into the end face of the fixing plate 421 and slidably engaged. An insertion groove for the telescopic plate 422 is formed on the end face of the fixing plate 421 away from the fixing sleeve 1. The positioning ring 41 is fixedly connected to the end of the telescopic plate 422 away from the fixing plate 421.

[0026] A pointer is also fixed to one end of the telescopic plate 422 near the fixed plate 421. The pointer is located on the surface of the fixed plate 421. A groove for the pointer to slide is provided on the surface of the fixed plate 421. The surface of the fixed plate 421 is also engraved with scales so that the nurse can adjust and determine the position of the positioning ring 41, that is, adjust and determine the length of the needle inserted into the skin.

The booster motor 64 enables long-term slow injection, freeing up the nurse's labor force. The nurse can monitor the syringe auxiliary device, and one nurse can monitor multiple syringe auxiliary devices at the same time, improving work efficiency.

[0028] Combination Figure 2 and Figure 5 The fixed sleeve 1 includes a sleeve body 11 and a sleeve cap 12. The sleeve cap 12 is detachably connected to the sleeve body 11, specifically by means of a snap-fit ​​connection. The sleeve body 11 and the sleeve cap 12 are hollow and used to install the syringe. Both the sleeve body 11 and the sleeve cap 12 have a handle hole 13 for the syringe handle to pass through, to ensure that the syringe is firmly fixed to the fixed sleeve 1.

[0029] A method of using a syringe auxiliary device includes: S1, fix the fixing component 5 to the patient's thigh, so that the angle control unit 3 is relatively fixed to the skin surface; S2, the staff measures the thickness of subcutaneous fat in the injection area by means of ultrasound or optical sensor or traditional manual measurement of subcutaneous fat thickness, then disinfects the skin, and then installs the syringe with the drug loaded into the fixed sleeve 1. S3, the angle control unit 3, by moving the sliding sleeve 32, changes the angle between the fixed sleeve 1 and the patient's skin surface, and fixes the position by the first locking member 321, thereby adjusting the angle at which the syringe needle enters the skin; S4, Adjust the needle positioning unit 4, and by adjusting the length of the telescopic member 42, position the positioning ring 41 on the needle. The length from the positioning ring 41 to the end of the needle is the length of the needle inserted into the skin. S5, the staff pushes the syringe to insert its needle into the skin and locks it through the second locking member 242. Then the booster motor 64 drives the booster plate 61 to slowly push the syringe to inject the drug. S6. After the injection is complete, remove the needle and take out the syringe.
