查，習知用於打點滴之注射針結構，大體設成：可變 曲之膠_又稱軟針)内套設金屬針，藉由金屬針之硬度 方可將膠質制人人體巾，後再㈣金料㈣膠質針留 於人體，俾可方·後再⑽f針注人所需之各種藥液， 又’膠質針未使用時，係以-護套包覆勝質針、金屬針， 使用後抽出金屬針時，再將護套套舍於金屬針換言之， 係需以人工將金;|針插人護套巾；上述，其實存在有下列 缺點：（1)注射完成後’仍需鮮持護套將金屬針插合， 除了使用不方便，亦會有不慎刺傷人之虞⑵護套雖套合 於金屬針’亦會由套合時未緊密、受碰撞而造成護套脫離 ，仍會有誤刺傷人之虞。 【新型内容】 本創作即是為改善上述習知之缺點’提供一種注射後 可自動形成安全防護之裝置。主要係：金屬針設有凸部、 並組設一可滑動之防護件，防護件設成由具有彈性之前片 、後片所構成，未使用時，防護件係收摺於膠質針之套筒 中，注射完成抽出金屬針時，防護件可同時滑動而形成前 3 M398432 片卡阻於金屬針之凸部、後片脫出金屬針之針頭外，形成 後片遮擋於針頭，而得防範金屬針刺傷人之功效。 【實施方式】 請參閱圖一、二、三、四，係金屬針1〇套合膠質針 12(又稱軟針），膠質針12外再套合護套14，金屬針1〇設 有凸部11、並組設有防護件20，該防護件20設成由具有 彈性之前片21、後片23構成，前片21設有通孔22供穿 組金屬針10，後片23亦設有滑孔24供穿組金屬針10， 且’後片23之滑孔24孔徑大於前>1 21之通孔22。 藉由上述之構造，本創作之使用、功效’茲再詳細說 明如下：如圖二所示，未使用時，防護件2〇係呈收摺於 膠質針12之套筒13中。使用時’如圖三所示，係將膠質 針12、金屬針1〇刺入人體中，即可如圖四所示，將金屬 針10抽出膠質針12，並使防護件20滑動至金屬針1〇之 針頭，此時因後片23之滑孔24孔徑較大、前片21之通 孔22直徑較小，因此可形成「後片23彈出針頭外、前片 21卡阻於金屬針10之凸部n」，即是形成「後片23遮擋 於針頭」，因此，可防止金屬針之針頭刺傷人，達到安全 防護之功效。 另，依上述之技術手段，本創作之防護件亦可設成如 圖五、六所示之多曲摺式防護件30，係前31、後片33間 設有兩個曲摺片，前、後片31、33亦設有通孔32、滑孔 34 ’如此之多曲摺片型態，屬本創作等效結構創意範疇内 4 M398432 綜上所述，本創作之結構裝置，確實具有極佳實用性 與增進功效，誠符合新型專利要旨，懇請賜准專利。 【圖式簡單說明】 圖一，本創作立體分解圖 圖二，本創作未使用時組合剖視圖 圖三，本創作使用中示意圖 圖四，本創作使用後示意圖 圖五，本創作防護件另一實施例立體圖 圖六，係圖五之組合剖視圖 【主要元件符號說明】 10金屬針 20、30防護件 11凸部 21、31前片 12膠質針 22、32通孔 13套筒 23、33後片 14護套 24、34滑孔Check, the structure of the needle used for the drip is generally set up: the variable glue _ also known as the soft needle) is set inside the metal needle, and the hardness of the metal needle can be used to make the human body towel, and then (4) Gold material (4) Glue needles are left in the human body, and the various liquids required for injection (10) f needles are injected, and when the glue needle is not used, the needles and metal needles are covered with a sheath. When the metal needle is pulled out, the sheath is placed on the metal needle. In other words, it is necessary to manually put the gold; the needle is inserted into the sheathing towel; the above has the following disadvantages: (1) After the injection is completed, it still needs fresh The sheath is used to insert the metal needle. In addition to the inconvenience of use, there will be accidental stab wounds. (2) Although the sheath is fitted to the metal needle, the sheath will be detached due to the tightness and collision caused by the sleeve. There will still be mistakes to stab people. [New content] This creation is to provide a device for automatically forming safety protection after injection to improve the above-mentioned shortcomings. Mainly: the metal needle is provided with a convex portion, and a slidable protective member is arranged, and the protective member is formed by a flexible front piece and a rear piece. When not in use, the protective piece is folded into the sleeve of the rubber needle. When the injection is completed, the guard can slide at the same time to form the front 3 M398432 piece stuck to the convex part of the metal needle, and the back piece is out of the needle of the metal needle, forming the back piece to block the needle, and the metal is prevented. The effect of acupuncture hurting people. [Embodiment] Please refer to Figure 1, 2, 3, 4, the metal needle 1 〇 sleeve rubber needle 12 (also known as soft needle), the rubber needle 12 and then the sheath 14, the metal needle 1 〇 with convex The portion 11 is further provided with a guard member 20, and the guard member 20 is formed by the elastic front piece 21 and the rear piece 23. The front piece 21 is provided with a through hole 22 for the metal needle 10, and the rear piece 23 is also provided. The slide hole 24 is for passing through the set metal needle 10, and the diameter of the slide hole 24 of the rear piece 23 is larger than the through hole 22 of the front > With the above construction, the use and effect of the present invention will be described in detail as follows: As shown in Fig. 2, when not in use, the shield member 2 is folded into the sleeve 13 of the gel needle 12. When used, as shown in Figure 3, the glue needle 12 and the metal needle 1 are pierced into the human body, as shown in Fig. 4, the metal needle 10 is pulled out of the gel needle 12, and the guard 20 is slid to the metal needle. In the case of the needle of the rear piece 23, the diameter of the sliding hole 24 of the rear piece 23 is large, and the diameter of the through hole 22 of the front piece 21 is small, so that the rear piece 23 can be formed outside the needle, and the front piece 21 is stuck to the metal needle 10. The convex portion n" forms "the rear piece 23 is shielded from the needle", so that the needle of the metal needle can be prevented from stabbing the person and the safety protection effect can be achieved. In addition, according to the above technical means, the protective member of the present invention can also be provided with a multi-folded guard member 30 as shown in FIGS. 5 and 6, and two bent pieces are arranged between the front 31 and the rear piece 33. The rear piece 31, 33 is also provided with a through hole 32, a sliding hole 34' such a multi-folded flap type, which belongs to the creative equivalent structure of the present invention. 4 M398432 In summary, the structural device of the creation does have Excellent practicality and enhanced efficiency, in line with the new patents, please grant patents.
