計ったものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly attaches a cylindrical movable cover to a medical injection needle, and after the operation (injection), the cover is slid until the tip of the injection needle is hidden, and the cover is accidentally injected. It is designed to prevent the needle from sticking and prevent infection with an injection needle.

ない様に保護している2. Description of the Related Art A conventional injection needle is protected by a cylindrical protective cover so that the needle will not bend or stick until it is used. However, when used, the protective cover is removed from the injection needle before use. For collection, hold the small container containing the reagent in one hand and the syringe in the other after collection.
Blood is transferred after inserting the needle into the container, and after use, the cover that was originally removed is covered from the tip of the needle to protect it from being stuck.

The injection needle (6) is covered with a cylindrical inner cover (1) that slides in the cylindrical outer cover (2). The structure is such that a cylindrical inner cover (Fig. 3) is provided inside a cylindrical outer cover (Fig. 2).
Push in, and cut (5) on the cylindrical outer cover (Fig. 2).
Since the tubular inner cover (FIG. 1) is inserted, the tubular outer cover can be easily opened by opening the tubular outer cover through the cut (5). 5)
Is ultrasonically welded or heat welded to prevent the cut (5) from opening. The cylindrical inner cover (1) is provided with a convex portion (4) in the shape of an arrowhead, the cylindrical outer cover (2) is provided with an opening (7), and the opening (7) is formed. The tubular inner cover (1) is provided in the tubular outer cover (2) and has a hooking portion (3) for fixing the tubular inner cover when the tubular inner cover is moved. The convex portion (4) with the protrusion protrudes from the opening (7) of the cylindrical outer cover. In this state, the cylindrical inner cover (1) is located rearward so that the injection needle has the cylindrical inner cover (1). Can be operated (injected) because it is more protruding

Immediately after that, the protrusion (4) in the shape of the arrow bar of the tubular cover (1) in the opening (7) of the tubular outer cover (2) pushes the hooking portion (3) wide to open the opening (8). When slid up to, the hooked portion (3) of the tubular outer cover (2) bites into the V-shaped portion after the convex portion (4) having the arrowhead shape, and the tubular inner cover (1) Since the hooking portion (3) of the cylindrical outer cover (2) tries to be tightened inward as the force of pushing the needle into the cylindrical outer cover (2), the cylindrical inner cover (1) protruding from the tip of the injection needle is It does not fall below the tip.

している。[Example] A cylindrical outer cover (Fig. 2), in which the cylindrical inner cover (Fig. 3) is pushed inside the cylindrical outer cover (Fig. 2).
Since the cutout (5) is provided on the cylindrical inner cover (Fig. 1), when the cylindrical inner cover (Fig. 1) is inserted, the cylindrical outer cover can be opened from the cut (5) to facilitate the cylindrical inner cover (1). After insertion, the cut (5) is ultrasonically welded or heat welded so that the cut (5) does not open. The cylindrical inner cover (1) is provided with an arrowhead-shaped protrusion (4), and the cylindrical outer cover (2) is provided with an opening (7). Is provided with a hooking portion (3) for fixing the tubular inner cover (1) so as not to return when the tubular inner cover (1) is moved. The tubular inner cover (1) is placed inside the tubular outer cover (2). Therefore, the convex portion (4) in the shape of an arrowhead projects from the opening (7) of the cylindrical outer cover (2).
【発明の効果】以上により使用後注射針は筒状内カバー
（１）が注射針の先端をカバーするので施術後に誤って
針が剌さることがなくなつた，又血液採取の場合でも筒
状内カバー（１）の先端は筒状になつていて針は筒の先
端より中にあるが、筒状内カバー（１）は注射針より少

とができるので注射針は筒状内カバー（１）の中にあっ
て針先が見えない状態でも血液を容器に移すことができ
る。病院から廃棄処理業者に渡っても同じく誤まって針
が剌さる心配がなくなった。As described above, since the injection needle after use has the cylindrical inner cover (1) which covers the tip of the injection needle, the needle is prevented from being accidentally dislodged after the operation, and it is cylindrical even when collecting blood. The tip of the inner cover (1) is tubular and the needle is inside the tip of the barrel, but since the tubular inner cover (1) is only slightly larger than the injection needle, put it in the mouth of the container containing the reagent. Since the injection needle is inside the cylindrical inner cover (1), blood can be transferred to the container even when the needle tip is invisible. When I went from a hospital to a waste disposal contractor, I no longer had to worry about the needles being accidentally blown.
