[0002] Subcutaneous injection involves injecting medication into the subcutaneous tissue. Common injection sites are the upper arm and the outer thigh. Insulin injection requires a certain level of vision and manual dexterity. The injection procedure is cumbersome and blood sugar control is difficult. It is especially difficult for elderly patients, visually impaired patients, and those with memory impairment. Insulin is a subcutaneous therapy, and the medication must be injected into the fat tissue between the skin and muscle. The classic method is to pinch the skin at the injection site with one hand and hold the injection needle with the other hand to insert it into the subcutaneous target.
[0003] Currently, subcutaneous injection procedures in oncology clinics still require nurses to hold the needle throughout the entire process. For drugs that require subcutaneous injection for more than 5 minutes, nurses face an increasing risk of occupational lumbar muscle strain, and the inability to free their hands leads to a significant decrease in nurses' work efficiency and a waste of medical human resources. In view of this, the present invention proposes a subcutaneous injection auxiliary device for oncology. Utility Model Content

[0037] Working principle:
[0038] In use, medical staff first place the device on the patient's leg. They can attach Velcro to the auxiliary rod 2 or use medical tape to secure the device to the patient's leg. Twisting the rotating handle 4 causes the connecting rod 3 to rotate. The connecting rod 3, through its threads, moves the two first ring sleeves 7 to both sides. As the first ring sleeves 7 move to both sides, they shift laterally through the V-groove 802, causing the clamping plates 804 of the rotating clamping member 8 to move towards the center, clamping the patient's skin to form an injection surface. Alternatively, the patient's skin can be clamped by hand first, and then the rotating handle 4 can be twisted to use the clamping plates 804 to clamp the patient's skin, forming the injection surface. Then, press the fixing plate 230 towards the adjusting component 220 to compress the second spring 222, causing the first insert plate 226 and the second insert plate 228 on the plug 224 to separate. Rotate to 30° to 45° to select a suitable angle, and then release the fixing plate 230 to allow the first insert plate 226 and the second insert plate 228 to reconnect and fix, thus fixing the angle of the fixing plate 230. Medical staff can then insert the scalp needle 301 into the patient and then fix the scalp needle 301 to the fixing plate 230 with medical tape. Medical staff can then leave after adjusting the time of the infusion pump 303.
