Embodiment
For the ease of the understanding of those skilled in the art, the utility model is made with reference to embodiment and accompanying drawing further
Explanation, the content that embodiment refers to not to restriction of the present utility model.The utility model is entered below in conjunction with accompanying drawing 1-4
The detailed description of row.
As shown in Figure 1, Figure 2 and Fig. 3, a kind of straight type safety indwelling needle described in the present embodiment, including shell 1 and for puncturing
When indwelling be provided with needle stand 4, institute in being provided with cavity 3, the bottom of the cavity 3 in intravenous indwelling portion 2, the shell 1
State and draw point 5 is provided with the center of needle stand 4, the bottom of the needle stand 4 is fixed with the first bullet along the axis extension of the draw point 5
Spring 6, one end and the bottom of needle stand 4 of first spring 6 are fixed, and the other end of first spring 6 is provided with for preventing
The exposed sheath 7 of the syringe needle 18 of draw point 5；Specifically, when draw point 5 inserts indwelling portion 2, the indwelling base 12 is against sheath 7
So that the first spring 6 compresses, sheath 7 is forced into the upper end of needle stand 4, and now the syringe needle 18 of draw point 5 is exposed；When by draw point 5 from institute
When stating the extraction of indwelling portion 2, axis direction stretching, extension of first spring 6 along draw point 5, the sheath 7 is with the first spring 6
Stretching, extension effectively prevents that syringe needle 18 is exposed, prevents syringe needle 18 from stabbing operating personnel, keep away until at the syringe needle 18 of the arrival draw point 5 of sheath 7
Exempt from draw point 5 to injure other people and spread germs；Stop block 8 is provided with the indwelling portion 2, is provided with and is used in the cavity 3
The screens 9 coordinated with stop block 8；Specifically, when the draw point 5 inserts indwelling portion 2, stop block 8 and the cooperation of screens 9 are utilized
Mutually withstand, indwelling portion 2 can be prevented to the excess compression of the first spring 6, while be also possible to prevent draw point 5 and be excessively inserting indwelling portion
In 2, play a part of limiting mutual alignment.
As shown in Figure 1, Figure 2 and Fig. 3, a kind of straight type safety indwelling needle described in the present embodiment, one end of the shell 1 is provided with
It is easy to the clasp 10 manually extracted.Specifically, straight type safety indwelling needle can be buckled on finger by operating personnel by clasp 10,
Improve the operating efficiency of operating personnel.
Such as Fig. 4, a kind of straight type safety indwelling needle described in the present embodiment, the sheath 7 is provided with to be passed through for the draw point 5
Through hole 11.Specifically, when the first spring 6 stretches or compressed, the draw point 5 both passes through the through hole 11 on the sheath 7.
Such as Fig. 3, a kind of straight type safety indwelling needle described in the present embodiment, the indwelling portion 2 includes the He of indwelling base 12
Needle guard 13, when the draw point 5 inserts indwelling portion 2, the indwelling base 12 make it that the first spring 6 is compressed against sheath 7, institute
State draw point 5 and pass through indwelling base 12 and needle guard 13, the sheath 7 is against the upper end of needle stand 4.Specifically, when draw point 5 inserts indwelling
During portion 2, the indwelling base 12 causes the first spring 6 to compress against sheath 7, and sheath 7 is forced into the upper end of needle stand 4, the pin
Sheath 7 is withstood in the upper end of seat 4, prevents the first spring 6 is overly compressed from causing to damage.
Such as Fig. 3, a kind of straight type safety indwelling needle described in the present embodiment, male member 14 is provided with the indwelling base 12,
The male member 14 by second spring 15 and the elastic connection of indwelling base 12, the inwall of the cavity 3 be provided with for
The pit 16 that the male member 14 coordinates, be provided with the pit 16 for against the inclined-plane 17 of male member 14, when by indwelling portion 2 from
When being extracted on cavity 3, the inclined-plane 17 make it that second spring 15 is compressed against male member 14.Specifically, when the draw point 5 inserts
During indwelling portion 2, the male member 14 of the indwelling base 12 is caught in pit 16, is ensured that draw point 5 is not easy to loosen, is also possible to prevent simultaneously
Because the effect of the first spring 6 causes draw point 5 to be separated with indwelling portion 2, operating difficulties is caused；When needing draw point 5 from pit 16
During middle extraction, the inclined-plane 17 is against male member 14 so that second spring 15 is compressed, and male member 14 inside contracts, so as to which male member 14 be taken off
Separated from pit 16, and then by draw point 5 with indwelling portion 2.
Such as Fig. 3, a kind of straight type safety indwelling needle described in the present embodiment, the male member 14 is hemispherical.Specifically, it is described
Male member 14 is hemispherical, and hemispherical is provided with arc side, is easy to inclined-plane 17 against cooperation.
