Detailed Description

The present invention will be further described with reference to the accompanying drawings.

The first embodiment.

A novel disposable insulin needle is shown in figures 1 to 3 and 7 to 8, and comprises a needle base 1, a needle body 2 and a protective sleeve 3; the needle seat 1 comprises an insulin pen assembling part 4 and a needle body assembling part 5 positioned above the insulin pen assembling part 4, the inner cavity of the insulin pen assembling part 4 is hollow, and a needle body assembling hole 6 is arranged at the center of the needle body assembling part 5; the needle body 2 is arranged in the needle body assembling hole 6 and penetrates through the needle body assembling part 5;

the needle base 1 is externally sleeved with a protective sleeve 3, the upper end of the protective sleeve 3 is closed, the lower end of the protective part 3 is open, and a first cavity 7 and a second cavity 8 communicated with the first cavity 7 are arranged in the protective sleeve 3; the needle body 2 and the needle body assembling part 5 are positioned in the first cavity 7; the second cavity 8 is adapted to the outer shape of the insulin pen fitting part 4.

The shield 3 comprises a first upper sleeve portion 9 and a first lower sleeve portion 10, the first upper sleeve portion 9 having a first cavity 7 therein and the first lower sleeve portion 10 having a second cavity 8 therein. The first upper sleeve portion 9 is provided with first ribs 11 uniformly on the outer periphery thereof, and the first ribs 11 have a triangular plate shape. The arrangement of the first reinforcing ribs can ensure the strength and rigidity of the protective sleeve 3, save the material consumption, reduce the weight and reduce the cost.

The upper end inner wall of the needle body assembly hole 6 is sequentially provided with a glue dispensing opening 19 and a glue storage cavity 20 from top to bottom, the glue dispensing opening 19 is communicated with the glue storage cavity 20, and the glue dispensing opening 19, the glue storage cavity 20 and the needle body assembly hole 6 are coaxially arranged. In this embodiment, store up and glue the chamber and be the calabash form, of course, in other embodiments, store up and glue the chamber and also can set up to other shapes, nevertheless this all belongs to the utility model discloses an equivalent replacement. When the point was glued, the point was glued mouthful and is glued the setting up of chamber with the storage and can fine control glue position and point and glue the shaping structure, has avoided leaking to glue and has overflowed gluey, ensures the fixed of needle body 2. The inner wall of the lower part of the first cavity (7) is provided with an annular rib 21, and the existence of the rib 21 enables the protection sleeve 3 and the needle seat 1 to be tightly connected after the protection sleeve 3 and the needle body assembling part 5 are assembled.

A plurality of leading groove 22 is evenly arranged on the outer wall of the insulin pen assembling part 4, one end of the leading groove 22 is R-shaped, and a plurality of inserting guide ribs 23 corresponding to the leading groove 22 are arranged on the inner wall of the second cavity 8.
