た結果次の考案に到達した。 In addition, in the above-mentioned I/V needle, since the U-shaped groove is formed in the midsection of the needle cap, the convex part must be pressed and deformed to guide it to the groove. It required a considerable amount of force and was difficult to operate. Furthermore, after introducing the convex part into the groove, the direction must be changed by 90° midway, so
The mating could not be done smoothly. Therefore, the inventor of the present invention has conducted extensive studies to solve the above problems and has arrived at the following idea.

る。(Means for Solving the Problems) The present invention provides a medical needle with a needle cap, which is composed of a needle base 2 on which a protrusion 5 is formed and a needle cap 3 attached to the needle base 2. The needle cap 3 is arranged from the bottom side. The extending groove 4a is the base.
forming an angle θ of 70° or less, forming grooves 4b continuously in the groove 4a substantially parallel to the bottom side, and forming a locking groove 7 at an end of the groove 4b; 4a, 4b, 7 are needle caps 3
The present invention provides a medical needle 1 with a needle cap formed on both left and right sides of the needle.
（作用）
突起部５を左または右に90°回転することによ

ある。(Example) Fig. 1 is a plan view of a medical needle 1 with a needle cap of the present invention, Fig. 2 is a partially enlarged view of the left side of the needle cap, and Fig. 3 is a partially enlarged view of the right side of the needle cap. It is a diagram.
キヤツプ付き医療針１は、突起部５を有する針
基２と、前記一連の溝４ａ，４ｂ，７を左右両側
に形成した針キヤツプ３とから構成されている。 The capped medical needle 1 is composed of a needle base 2 having a protrusion 5, and a needle cap 3 having the series of grooves 4a, 4b, 7 formed on both left and right sides.
底辺から延びる溝４ａは底辺と70°以下の角度
θをなすように形成し、溝４ｂは前記底辺と略平
行に溝４ａと連続して形成するとともに係止溝７
は溝４ｂの端部に形成されている。 The groove 4a extending from the bottom side is formed to form an angle θ of 70° or less with the bottom side, and the groove 4b is formed substantially parallel to the bottom side and continuous with the groove 4a, and the locking groove 7
is formed at the end of the groove 4b.
角度θが70°を越えると溝４ａが針を引き抜く
方向にほぼ同一線上にならび、突起部５が係止溝
７、溝４ｂを経て溝４ａから抜けやすくなるので
好ましくない。 If the angle θ exceeds 70°, the grooves 4a will be aligned substantially in the direction in which the needle is pulled out, and the protrusion 5 will easily come out of the groove 4a via the locking groove 7 and the groove 4b, which is not preferable.
前記一連の溝４ａ，４ｂ，７は、針キヤツプ３
を形成する時に同時に形成すれば良くコスト的に
も安価に製造できる。 Said series of grooves 4a, 4b, 7 form the needle cap 3.
It can be manufactured at low cost if it is formed at the same time as forming.
係合に際しては、突起部５を左または右に90°
回転することにより、突起部５は針キヤツプ３の
底辺から延びる溝４ａ，４ｂを経て係止溝７にス
ムーズに係止される。 When engaging, turn the protrusion 5 90° to the left or right.
By rotating, the projection 5 is smoothly locked into the locking groove 7 through the grooves 4a and 4b extending from the bottom of the needle cap 3.
また前記一連の溝４ａ，４ｂ，７は針キヤツプ
３の内側のみに形成することもできる。 The series of grooves 4a, 4b, 7 can also be formed only on the inside of the needle cap 3.

The protrusion 5 is a groove 4 extending from the bottom of the needle cap 3.
a, and can be smoothly locked in the locking groove 7 through the grooves 4a and 4b.
Therefore, the needle cap 3 can be smoothly engaged with the needle base 2 without requiring any force.

傷つけるようなことはない。(2) Also, when removing the needle cap 3 from the needle base 2, the groove 4b is formed approximately parallel to the base of the needle cap 3, and the groove 4a is formed at an angle of 70 degrees or less with the base, so that it can be removed instantly. No great force is applied, and there is no risk of the needle suddenly becoming exposed and injuring the worker's hands or fingers. Also, needle cap 3
By forming a series of grooves 4a, 4b, and 7 in the groove 4a and by forming a locking groove 7 at the end of the groove 4b, it is possible to prevent the needle cap 3 from loosening during manufacturing or transportation. Since it can be removed from the needle base 2 step by step in the order of 7, 4b, and 4a, it does not require strong force compared to the conventional Utility Model Publication No. 56-2974 in which a concave portion was formed in the needle base. , the needle cap 3 can be removed, and the needle will not be suddenly exposed and injure the hands and fingers as in the case described above.
