In figure: cylinder 1, connecting column 11, fin 12, lug 13, first through hole 14, the second through-hole 15, syringe needle 2, needle holder 21, cock body 3, limiting slot 31, loudspeaker oral area 32, sealer 4, core bar 5, groove 51, press head 52, piston 6, convex body 61, sealing lip 62, limit plate 7, clamp 71.

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.

The bottom of the cylinder 1 is run through equipped with the second through-hole 15 and seals the second through-hole by sealer 4 in 1 outer wall of cylinder 15, second through-hole 15 is opposite with about 3 cock body.The quantity of second through-hole 15 is three and along the bottom of cylinder 1 It is circumferential uniformly distributed.When being extracted into blood in cylinder 1, sealer 4 is removed, up along the second through-hole 15 by the needle of head vacuum tube with a needle It inserts, blood will enter vacuum tube along the needle after which penetrates cock body 3, very easy to use.

The center of the cock body 3 is equipped with the loudspeaker oral area 32 that diameter is gradually increased from the bottom up, the lower end of loudspeaker oral area 32 Diameter it is equal with the internal diameter of connecting column 11.The setting of loudspeaker oral area 32 is convenient to drain blood.

The top of the core bar 5 is equipped with the press head 52 that size increases.The setting of press head 52 facilitates the finger of people to carry out Operation.

The lower part of the core bar 5 is equipped with groove 51, and the inner edge of the piston 6 is equipped with the convex body 61 for being caught in groove 51, wherein The annular outer wall of lower part of the convex body 61 in addition to enveloping core bar 5, also envelopes the bottom face of core bar 5, and the outer rim of piston 6 is formed Lower two sealing lips 62 being interference fitted with 1 inner wall of cylinder, so that piston 6 has good sealing performance in moving process.

The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model Within the scope of shield.
