The multiple hemostix of artery

Technical field

The utility model is related to medical devices fields, more particularly, to a kind of multiple hemostix of artery.

Background technology

Traditional hemostix is syringe-type structure, after blood drawing stops, before extracting syringe needle, easy tos produce blood back, Er Qiechuan The hemostix stroke of system is limited, and blood drawing capacity is fixed, if to take out more blood, needs in addition to have an acupuncture treatment again, increases patient suffering, Or large capacity syringe is directly replaced, volume increases, and storage is inconvenient.

Utility model content

The utility model be solve the problems, such as it is set forth above to providing a kind of multiple hemostix of artery, including needle thus Head, syringe and push head device, the syringe needle is fixed on syringe, and is interconnected, and the push head device is arranged in syringe Inside, is symmetrically arranged with protruding rail on the syringe inner wall, and the push head device includes preceding seal head and rear seal head, described preceding close It fits closely between end socket and rear seal head, is connected between each other by shaft, on the preceding seal head and rear seal head respectively It is provided with through-hole, the preceding seal head both sides are symmetrically arranged with female rail, and the protruding rail and female rail cooperate, the rear seal head Rear portion is provided with vacuum tube, and the vacuum tube rear portion is provided with handle.

Preferably, the through-hole is arranged to sector structure.

The utility model has the beneficial effects that：The structure design of the utility model is reasonable, can by syringe and vacuum tube into Row is taken a blood sample twice, is increased blood sampling capacity, is reduced hemostix volume, be readily transported, cost-effective, can also anti-non-return by vacuum tube Blood phenomenon, safety and sanitation.

Specific implementation mode

All features disclosed in this specification or disclosed all methods or in the process the step of, in addition to mutually exclusive Feature and/or step other than, can combine in any way.

Any feature of this specification, unless specifically stated, can be equivalent by other or replacement with similar purpose it is special Sign is replaced.That is, unless specifically stated, each feature is an example in a series of equivalent or similar characteristics.

The multiple hemostix of a kind of artery as shown in Figure 1, Figure 2 and Figure 3, including syringe needle 1, syringe 2 and push head device 3, institute It states syringe needle 1 to be fixed on syringe 2, and is interconnected, the push head device 3 is arranged inside syringe 2, in the syringe 2 Protruding rail 2.1 is symmetrically arranged on wall, as shown in figure 4, the push head device 3 includes preceding seal head 3.1 and rear seal head 3.2, institute It states and is fitted closely between preceding seal head 3.1 and rear seal head 3.2, connected between each other by shaft 3.3, the preceding seal head 3.1 and rear seal head 3.2 on be respectively arranged with through-hole 3.4,3.1 both sides of preceding seal head are symmetrically arranged with female rail 3.5, described Protruding rail 2.1 and female rail 3.5 cooperate, and rear 3.2 rear portion of seal head is provided with vacuum tube 3.6,3.6 rear portion of the vacuum tube It is provided with handle 3.7.

The through-hole 3.4 is arranged to sector structure.

It is symmetrically arranged with fixed ear on the syringe 2.

It is both provided with containing mark scale on the syringe 2 and vacuum tube 3.6.

In use, syringe needle 1 penetrates artery, twitches handle 3.7 and draws blood, preceding seal head 3.1 passes through protruding rail 2.1 With female rail 3.5 as being oriented to, blood is pumped into the cavity of syringe 2, when blood drawing is to end of travel, such as also needs to draw blood, it will Handle 3.7 rotates, by the through-hole 3.4 on preceding seal head 3.1 and rear seal head 3.2 to it, the negative pressure that vacuum tube 3.6 passes through vacuum Blood is continued to be pumped into vacuum tube 3.6, syringe needle 1 is extracted after reaching scale, completes blood sampling；It has been drawn blood by syringe 2 when usually Cheng Hou also can be rotated to handle 3.7 and carry out additional blood drawing, and simultaneously extracts syringe needle, can avoid blood and returns to blood vessel from syringe The phenomenon that.

The structure design of the utility model is reasonable, can twice be taken a blood sample by syringe and vacuum tube, and blood sampling capacity is increased, Reduce hemostix volume, is readily transported, it is cost-effective, blood return phenomenon, safety and sanitation can also be prevented by vacuum tube.

The utility model is not limited to specific implementation mode above-mentioned.The utility model expands to any in this specification The new feature of middle disclosure or any new combination, and disclose any new method or process the step of or any new group It closes.
