一般而言，注射器都會在其針頭處配置有一針頭蓋，該針頭蓋可保護針頭在使用前不會受到損傷及汙染，而使用後也可將該針頭蓋蓋回，避免使用過的針頭扎傷後續經手人員。然而，由於該針頭蓋的口徑小，且是以軸向套合的方式蓋合於針頭外，故護理人員需非常小心地將該針頭蓋對準蓋回，否則很容易被針頭的針體扎傷而受到感染。 In general, the syringe is provided with a needle cover at the needle. The needle cover protects the needle from damage and contamination before use, and the needle cover can be covered back after use to avoid the use of the needle. Follow-up personnel. However, since the needle cap has a small diameter and is covered with the needle in an axially fit manner, the caregiver needs to very carefully align the needle cover with the cover, otherwise it is easily pinned by the needle. Injury and infection.

為此，目前市面上已有許多習知的針頭防護蓋，可設置於注射器的針筒與針頭之間，只要在針頭使用過後以手指輕輕推動，該習知針頭防護蓋的護套即可由外側翻向中心，從針頭的側向套合其針體，使針體被收入該護套中；如此，可由十分簡易的操作方式，提升護理人員的使用注射器時的安全性及效率。 To this end, there are many conventional needle protection covers available on the market, which can be placed between the syringe barrel and the needle. As long as the needle is gently pushed by the finger after the needle has been used, the sheath of the conventional needle protection cover can be The outer side is turned to the center, and the needle body is sleeved from the side of the needle so that the needle body is collected into the sheath; thus, the safety and efficiency of the caregiver using the syringe can be improved by a very simple operation mode.

然而，習知的針頭防護蓋大多不具有通用性，需要與指定型態的針筒或針頭配合方可使用，故無法適用於一般通常規格的注射器，且只能向特定廠商進貨，使得購買注射器之成本難以降低；類似的實施例已揭露於中華民國公告第M516984號及第M546229號等專利案當中。 However, the conventional needle guard covers are mostly non-universal and need to be used in combination with a designated syringe or needle, so that they cannot be applied to a general-purpose syringe and can only be purchased from a specific manufacturer, so that the syringe can be purchased. The cost is difficult to reduce; similar embodiments have been disclosed in the Republic of China Announcement Nos. M516984 and M546229.

另一部分的習知針頭防護蓋則是需要多設一轉接件來連接護套，組裝時，需由該轉接件的一端緊套於針筒，並將針頭緊套於該轉接件的 另一端，故組裝步驟較為繁瑣且不易操作；類似的實施例已揭露於中華民國公告第M494616號及第M527330號等專利案當中。 Another part of the conventional needle protection cover needs to be provided with an adapter to connect the sheath. When assembling, one end of the adapter needs to be tightly sleeved on the syringe, and the needle is tightly sleeved on the adapter. At the other end, the assembly procedure is cumbersome and difficult to operate; similar embodiments have been disclosed in the Republic of China Announcement Nos. M494616 and M527330.

有鑑於此，習知的針頭防護蓋確實仍有加以改善之必要。 In view of this, the conventional needle guard cover does have to be improved.
