Specific embodiment
The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning
Same or similar element or element with the same or similar functions are indicated to same or similar label eventually, below by ginseng
The embodiment for examining attached drawing description is exemplary, it is intended to for explaining the utility model, and should not be understood as to the utility model
Limitation.
Embodiment 1:
As shown in Figure 1, a kind of safe needle of retaining on artery, including needle of retaining on artery and its protective case of connection 4, the artery
Remaining needle includes steel needle 1, indwelling tube 2 and casing seat 5, and 5 one end of described sleeve pipe seat connects indwelling tube 2, and the steel needle 1 is set to set
In tube socket 5 and indwelling tube 2,1 tail portion of steel needle is provided with steel needle pin 3, and 5 other end of described sleeve pipe seat is connect with steel needle pin 3, institute
It states casing seat 5 and 3 junction of steel needle pin is connected with protective case 4, the protective case 4 includes connector 41 interconnected and sleeve
42, the connector 41 is connect with casing seat 5, and 42 side of sleeve is provided with sliding slot 8, and the steel needle pin 3 is placed in sliding slot 8
