The needle is wounded and even infected with the disease.
當打完針後要蓋上護蓋將針蓋住之動作稱為「回針」(一手拿針筒、另一手拿護蓋)，其目的是要避免他人(含護理人員、清潔人員、廢棄物處理人員等)被刺到。然而，在回針時，若護理人員稍有分心或稍為不慎而沒對準，就很容易不小心刺到手，進而有被感染到特定疾病之風險(例如：愛滋病．．．．等)。 When the needle is finished, the cover should be covered with a cover to call the needle back (handle the needle in one hand and the cover in the other). The purpose is to avoid others (including nursing staff, cleaning staff, and waste). The handler, etc.) was stabbed. However, when the needle is turned back, if the caregiver is slightly distracted or slightly careless and misaligned, it is easy to accidentally stab the hand and risk being infected with a specific disease (eg AIDS, etc.) .
另外，由於使用過後之針頭沒有被破壞，因此會發生多人共用同一針頭之案例，並導致共用針頭的人感染血液性傳染之疾病，例如C型肝炎、愛滋病．．．．等。 In addition, since the needle after use is not destroyed, there will be cases in which multiple people share the same needle, and people who share the needle are infected with blood-borne diseases such as hepatitis C and AIDS. . . .
