Description
本創作是一種彎針器,尤指一種可以將已使用過的注射針頭彎折變形防止重複使用的彎針器。This creation is a needle bender, especially a needle bender that can bend and deform the used injection needle to prevent repeated use.
注射針通常在醫療行為上是被用來將藥劑施打入人體的一種工具,由於注射針要將藥劑施打入人體內,因此使用過的注射針頭的注射針上很容易沾染人體的血液,人類的許多疾病或病毒都是透過接觸血液感染,因此注射針頭使用過後需要直接以醫療廢棄物處理,不能重複使用。但是注射針頭是否有被使用過很難重外觀辨識,因此仍然有可能在沒有注意的情況下重複使用注射針頭。The injection needle is usually a tool that is used to drive the medicine into the human body in medical behavior. Since the injection needle needs to drive the medicine into the human body, the injection needle of the used injection needle is easily contaminated with human blood. Many human diseases or viruses are infected through contact with blood, so after use, the injection needle needs to be directly treated as medical waste and cannot be reused. However, it is difficult to recognize the appearance of whether the injection needle has been used, so it is still possible to reuse the injection needle without paying attention.

在配合圖式說明本創作的說明性實施例的詳細說明之下將可更清楚瞭解本創作。The creation will be more clearly understood under the detailed description of the illustrative embodiments that illustrate the creation in conjunction with the drawings.
本創作是一種用來將已使用過的注射針彎曲避免重複使用的彎針器。參閱第1~4圖所示,彎針器10包括一個殼體20,殼體20較佳由對稱的一個第一部分22以及一個第二部分24共同組成,殼體20包括一個彎針部26以及提供手指扣住的一個手持部28,殼體20進一步包括從手持部28的端面朝向彎針部26延伸的一個活動孔30,活動孔30包括一個第一段32以及內徑大於第一段32的一個第二段34,第二段34延伸至手持部28的端面形成開口,第一段32則與彎針部26的端面隔開一個距離,第一段32與第二段34的交界處形成一個階面36。This creation is a needle bender used to bend the used injection needle to avoid repeated use. Referring to FIGS. 1-4, the
殼體20進一步包括從彎針部26表面延伸且與活動孔30的第一段32相交的一個注射針容置空間39,注射針容置空間39包括從彎針部26的表面延伸且為錐形的一個擴大孔42以及與擴大孔42隔開的一個針槽40,注射針容置空間39進一步包括延伸在針槽40與擴大孔42之間的一個退針槽44。殼體20又包括與注射針容置空間39連接的一個容槽46。活動孔30的第一段32沿著活動孔30的軸向位於容槽46與第二段34之間,在活動孔30的第一段32的內周面設置有兩個限位槽38,並且在容槽46與限位槽38之間延伸一個切槽48。所述注射針容置空間39適用於提供容置一個注射針頭73,注射針頭73包括一個注射針74以及結合在注射針74一端的一個連接座76(通常是塑膠製),注射針頭73用來與一注射筒的接嘴套接,透過擠壓注射筒的活塞能夠將藥劑使用注射針頭73打入人體內,所述針槽40的尺寸大致上略大於注射針74的外徑(如第3圖所示),而退針槽44大於針槽40但略小於擴大孔42。The
本創作的彎針器10進一步包括一個頂塊50,頂塊50包括一個外端52以及從外端52延伸的一個缺口54。頂塊50容置在容槽46內,容槽46內容置兩個回復彈簧56,兩個回復彈簧56朝向手持部28抵壓頂塊50。The
彎針器10又包括可移動地與活動孔30結合的一個壓桿58,壓桿58包括一個桿體60,桿體60包括本體段62以及外徑小於本體段62的一個延伸段64,壓桿58進一步包括形成在本體段62末端的一個施力部66,延伸段64包括Y形的一個末端72以及位於末端72與施力部66之間的一個抵壓部70,壓桿58包括對應限位槽38的兩個滑塊68。壓桿58的本體段62可移動地容置在活動孔30的第二段34,延伸段64可移動地容置在第一段32,末端72及抵壓部70容置在切槽48與限位槽38內(如第3圖所示),所述頂塊50的外端52抵靠於壓桿58的末端72,使得壓桿58位於兩個滑塊68的後端貼靠於限位槽38的端面上(後退位置),參閱第3、4圖所示,在這樣的狀態下,頂塊50的缺口54與針槽40及退針槽44對齊,因而允許將注射針頭73穿入。The
參閱第4圖所示,在壓桿58位於後退位置時,允許將使用過的注射針頭73穿入注射針容置空間39內。假設要彎曲使用過的注射針頭73,首先將注射針頭73從注射筒上拆卸下來,進一步將注射針74穿過擴大孔42、退針槽44以及頂塊50的缺口54而穿入針槽40內,並且注射針頭73的連接座76位於擴大孔42中,值得注意的是,由於退針槽44尺寸小於連接座76,因而連接座76無法進入,如第3圖所示,注射針74大約中間的位置與壓桿58的抵壓部70對齊。Referring to FIG. 4, when the
使用者的其中兩根手指扣在殼體20手持部28上,並且另一根手指(通常是拇指)抵靠在壓桿58的施力部66上,施力壓桿58的施力部66推動壓桿58,壓桿58位移至本體段62抵靠於階面36就無法繼續朝靠近彎針部26位移,壓桿58的抵壓部70擠壓注射針74,,此外由於注射針74的末端(尖端)位於孔徑略大的針槽40內,因而注射針74的末端無法轉動,進一步注射針74受到壓桿58的抵壓部70壓迫會以針槽40與退針槽44交界處為支點彎曲變形(如第5圖所示),在注射針74彎曲變形之後釋放壓桿58,頂塊50受到兩個回復彈簧56作用而朝向手持部28的方向抵壓壓桿58移動退回至後退位置。值得一提的是,退針槽44與缺口54的尺寸允許彎曲後的注射針74移動脫離注射針容置空間39,因而被彎曲後的使用過的注射針74能夠從注射針容置空間39中取出(如第6圖所示)。Two of the user's fingers buckle on the
本創作的彎針器10能夠將已經使用過的注射針頭73簡易且安全地彎曲產生永久變形,避免被使用過的注射針頭73被重複使用。The
