Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments described in the present invention, and for those skilled in the art, other drawings can be obtained according to the drawings without creative efforts.

FIG. 1 is a front view of an embodiment of a small indwelling needle according to the present invention.

Detailed Description

The present invention is described in detail below with reference to various embodiments, but it should be noted that these embodiments are not intended to limit the present invention, and those skilled in the art should be able to make equivalent changes or substitutions in functions, methods, or structures according to the embodiments without departing from the scope of the present invention.

The utility model provides a small-size needle of keeping somewhere, it includes: a three-way catheter seat, a steel needle, a needle seat, a hose and a color three-way;

The technical solution of the small indwelling needle according to the present invention will be described below by way of example with reference to an embodiment.

As shown in FIG. 1, the small indwelling needle of the present embodiment includes: three-way pipe seat 1, steel needle 2, needle file 3, hose 4 and various tee bend 5.

The three-way catheter hub 1 has: a conduit seat body 11 which is arranged in a front-back through way, and a branch pipe 12 which is connected with one side of the conduit seat body 11.
