Specific embodiment
The utility model is further described with reference to the accompanying drawings and detailed description:
As shown in Figure 1 and Figure 2, a kind of medical hemostix, including cylinder 1, syringe needle 2, core bar 5 and piston 6, the cylinder 1
Upper end opening and the space of core bar 5 and piston 6 is accommodated in internal formed, the bottom of cylinder 1, which is run through, is equipped with connecting column 11, connecting column
11 are located at the bottom centre of cylinder 1 and extend downwardly, and connecting column 11 is integrally formed with cylinder 1 and connecting column 11 is connected to cylinder 1
Inner space, connecting column 11 are used for Fast Installation syringe needle 2.
The syringe needle 2 is set on connecting column 11 by the needle holder 21 on its top, and syringe needle 2 is also connected to the inside of cylinder 1
Space, these are the prior art, not described in detail herein.
The core bar 5 is moved up and down by being set in the piston 6 of its bottom end along 1 inner wall of cylinder, the annular of the cylinder 1
The bottom of inner wall is equipped with fin 12, and the bottom of cylinder 1 is fitted with cock body 3, and the outer rim of the cock body 3 is equipped with to match with fin 12
Limiting slot 31, the quantity of the fin 12 and limiting slot 31 is two.Two fins 12 are spaced apart, cock body 3 and cylinder 1
The bottom surface (where removing connecting column 11) of circumferential inner wall snug fit bottom surface and the cylinder 1 of cock body 3 simultaneously of bottom be close to
Cooperation.
The top of the cylinder 1 is symmetrically arranged with two lugs 13, and lug 13 supports support for the finger of people.
Through first through hole 14 is equipped on the lug 13, it is fitted with limit plate 7 on lug 13, the limit plate 7
Lower end surface is equipped with clamp 71 with 14 tight fit of first through hole, and the quantity of the first through hole 14 and clamp 71 is three.Three
The distribution triangular in shape of a first through hole 14, clamp 71 will not be deviate from easily after being inserted into first through hole 14 by force, need to use centainly
Power could pull up limit plate 7 from lug 13, therefore be enough to play position-limiting action when normal use, after wherein clamp 71 is inserted into
Bottom end beyond first through hole 14.
The distance between inner edge of two limit plates 7 is greater than the outer diameter of core bar 5 and is less than the outer diameter of piston 6, therefore limits
Plate 7 does not influence moving up and down for core bar 5, while when piston 6 is moved to the top can be limited to limit plate 7 and can not deviate from.
