按，一般醫療用之注射針筒，主要係設有一針筒、一推桿及一針頭所組成，而習知的注射針筒在要注射藥劑之前，須先將針頭組設於針筒上，再以針頭插設入藥劑瓶內，藉由抽拉插設於針筒內的推桿，利用針頭將藥劑吸引入針筒內，再將針頭***病患身上並藉由壓持推桿將針筒內的藥劑擠壓注射入病患身體內，才可完成藥劑之注射，然，習知之注射針筒，在注射藥劑之操作過程較為麻煩，且由於針頭具有細長之針體，在使用過程中，醫護人員容易發生被針扎傷的意外，故大都會於針頭上套設一針頭套來避免針扎之意外，但常因在注射完藥劑後，針頭套欲套回針頭上時，仍有不小心被注射針頭扎傷而有遭受病毒感染的風險之虞，且習知之注射針筒及針頭套等之使用量，造成大量的醫療廢棄物產生，醫療廢棄物之處理費用極為龐大。According to general injection syringes for general medical use, they are mainly composed of a syringe, a push rod and a needle, and the conventional injection syringe must be set on the syringe before injecting medicine. Then the needle is inserted into the medicine bottle, and the push rod inserted in the syringe is pulled by pulling, the medicine is drawn into the syringe with the needle, the needle is inserted into the patient, and the needle is held by pressing the push rod The medicine in the cylinder is squeezed and injected into the patient's body to complete the injection of the medicine. However, the conventional injection syringe is more troublesome in the process of injecting the medicine, and because the needle has a slender needle body, during use, Medical personnel are prone to accidents caused by needle puncture, so most people will put a needle cover on the needle to avoid the accident of needle puncture. However, often after the injection of the drug, the needle cover is intended to be put back on the needle.
