Description
本創作關於一種注射器,尤指一種可確保針頭與藥劑瓶安全防護功能的注射器。This creation relates to a syringe, and more particularly to a syringe that ensures the safety of the needle and the vial.
現有注射器之組成構造,其主要包含有一用以裝填藥劑瓶之注射器本體,注射器本體之一端設有針頭,注射器本體之另一端設有注射推進組件,並於注射器本體具有針頭之一端套設有一可拆組套蓋,將針頭罩蓋於內。於注射前,須預先將藥劑瓶裝填於注射器本體,並使針頭伸入藥劑瓶內,於注射時,將套蓋取下,以針頭刺入待注射者體內,接續按壓注射推進組件,將藥劑瓶內的液態藥劑注入被注射者體內。The composition of the existing syringe mainly comprises a syringe body for loading a medicament bottle, the syringe body is provided with a needle at one end thereof, and the other end of the syringe body is provided with an injection propulsion assembly, and the syringe body has one end of the needle sleeve Unpack the cover and cover the needle cover. Before the injection, the medicine bottle should be prefilled into the syringe body, and the needle is inserted into the medicine bottle. At the time of injection, the cover is removed, the needle is inserted into the body to be injected, and the injection advancement assembly is successively pressed to apply the medicine. The liquid medicament in the bottle is injected into the body of the injected person.
惟現有注射器之組成構造中,其針頭為套蓋結合於注射器本體一端,因套蓋與注射器本體間係為單純的卡接構造,因針頭非處於完全密封的無菌環境下,且易受外力作用而脫離,造成針頭受到污染,造成注射器之使用安全性不足之缺陷,此外,該注射器裝填藥劑時,易有氣泡存留,而須進一步將氣泡擠出,且擠出氣泡時,易連接藥劑擠出,而須增加藥劑裝填量,故該注射器之使用,其困難度與技術性偏高,而不利於緊急注射之用途。However, in the composition of the existing syringe, the needle is a cover that is coupled to one end of the syringe body, because the sleeve and the syringe body are simply snapped together, because the needle is not in a completely sealed aseptic environment, and is susceptible to external force. The detachment causes the needle to be contaminated, which causes defects in the safety of the use of the syringe. In addition, when the syringe is filled with the medicament, bubbles are easily retained, and the bubbles are further squeezed out, and when the bubbles are squeezed, the medicine is easily connected. The dosage of the drug must be increased, so the difficulty of using the syringe is technically high, which is not conducive to the use of emergency injection.
再者,現有注射器之組成構造中,注射推進 組件僅裝設於注射本體中,並無其他安全防護機制,故注射推進組件易受外力作用而將藥劑瓶內的液態藥劑通過針頭射出,造成注射器使用上之不便。Furthermore, in the composition of the existing syringe, the injection advances The assembly is only installed in the injection body, and there is no other safety protection mechanism. Therefore, the injection propulsion assembly is easily subjected to external force to inject the liquid medicine in the medicine bottle through the needle, which causes inconvenience in the use of the syringe.
