Description
Technical field
This utility model relates to technical field of medical instruments, is specifically related to a kind of hemostix.
Background technology
In medical apparatus and instruments, use in a large number disposable syringe, be mainly made up of syringe, syringe needle and piston handle, piston handle is provided with piston, when use by syringe needle on syringe end, the slip by piston handle in syringe reaches the object of injection.But the syringe inner wall smooth of existing syringe, cause when blood sampling syringe inside piston handle at all cannot be from bullet, therefore need portable piston handle in the time of blood sampling, result is mobile syringe needle in blood collection procedure easily, patient is caused suffering, also easily form haemolysis, arterypuncture success rate is reduced.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide the hemostix of a kind of good sealing effect and energy aerofluxus.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of hemostix, comprise syringe, described syringe inside is provided with piston, described piston is removably connected with push rod and slides at described syringe inner sealing, the cross section of described syringe and piston is circular, on the excircle of described piston, be provided with the annular groove of one or more, in described annular groove, be provided with sealing ring, in the middle of described piston, be provided with cavity, on the upper surface of described piston and lower surface, be provided with through hole, described through hole communicates with described cavity, in described cavity, be provided with the ventilate filter membrane of not water flowing of multilamellar, in the through hole of the upper surface of described piston, be provided with chock plug, the front end of described syringe is provided with needle guard, on described needle guard, be provided with syringe needle, described needle guard inside is provided with check valve.
Further improvement as technique scheme:
The outer setting of described syringe has the prominent circle of multiple annulars.
On described syringe needle, be arranged with seal closure.
The quantity of described annular groove is four.
The number of openings arranging on the upper surface of described piston is two, and described chock plug is rubber stopper.
On described syringe, be provided with graduation mark.
Compared with prior art, the beneficial effects of the utility model:
On the excircle of the piston of hemostix of the present utility model, be provided with multi-turn sealing member, play good sealing function, on piston, be provided with can not draining of aerofluxus passage, make piston handle capable of expansion and contraction, not can blood sampling process in mobile syringe needle, the success rate that improves arterypuncture, needle guard inside is provided with check valve in addition, prevents that air from entering.Separately be provided with the prominent circle of annular can allow user easy to operate, be difficult for slippage.On syringe needle, be provided with seal closure, can prevent that air from entering in syringe needle.On syringe, be provided with graduation mark, conveniently gather intuitively quantitative blood.
