Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
As shown in Figure 1, 2, the utility model provides a kind of medical inspection section blood sampler, including one end closing is separately
The tubulose exhaust tube main body 10 of one end open and the movable cork 11 and push rod 12 being arranged in exhaust tube main body 10, the pumping
There are two the first column tube 20 of exterior domain in perforation exhaust tube main body 10 and for arrangement on the end face of the blind end of tracheae main body 10
Two column tubes 30 are arranged with syringe needle 40 on first column tube 20, blood reservoir 50, first column are arranged on the second column tube 30
Round table-like flexible gear pipe 21 is disposed at the nozzle at 20 both ends of pipe, the axial line of round platform is flat with the axial line of exhaust tube main body 10
Neat and round platform upper table surface closes on the end face arrangement of the blind end of exhaust tube main body 10, and the blood sampler further includes and the
The plug 60 of one column tube 20, the second column tube 30 adaptation.When specifically used, the second column tube 30 is blocked using plug 60, by syringe needle 40
It is inserted into venous puncture blood, the round table-like flexible gear pipe 21 in the first column tube 20 allows blood unidirectionally to flow into exhaust tube main body
In 10, after stopping drawing blood, internal pressure action prevents the suck-back of blood, it is therefore prevented that pressure is not on flexibility gear pipe 21
Plug 60, is then removed and is blocked the first column tube 20, on the second column tube 30 in grafting by blood suck-back phenomenon caused by consistent
Blood reservoir 50 pushes blood sample to be detected in blood reservoir 50.Medical inspection section provided by the utility model blood
Liquid sampler can effectively prevent the suck-back of blood, while can bring interference to subsequent inspection to avoid contacting blood oxygen.
Further, for the suck-back of more preferable anti-Hemostatic Oral Liquid, in the inner tubal wall upper edge pipe range of the exhaust tube main body 10

When pulling is drawn blood, annular convex 13 keeps out limit to movable cork 11, avoids after removing to the pulling force of push rod 12 because of pressure
It is strong inconsistent to lead to blood suck-back phenomenon.
Further, in order to avoid the reciprocating motion of movable cork 11 is excessively laborious, the height of the annular convex 13
Preferably 0.2-0.8mm.
Further, the syringe needle 40 includes the hollow needle body 41 of front end and the tubular base 42 of rear end, 42 sets of pedestal
It is connected on the first column tube 20.
Further, it in order to effectively control and observe in real time the blood volume of blood drawing, is arranged in the exhaust tube main body 10
There is graduation mark 14.
Further, in order to avoid blood is excessively influenced in storage by ambient temperature, the blood storage
Device 50 includes being accommodated in inner cylinder 52 in outer barrel 51, the barrel arranged adjacent of inner cylinder 52 and outer barrel 51 and with the lid of tube port position arrangement
Plate 53 forms sealing structure, and cover board 53 is equipped with soft pipe 54, and the other end of soft pipe 54 is equipped with connecting tube 55 and 30 phase of the second column tube
Socket, in this way, the blood sample in inner cylinder 52 can avoid the influence of external environment as possible.
Medical inspection section provided by the utility model blood sampler, it is simple in structure, it can effectively avoid drawing blood
Blood suck-back phenomenon in the process, meanwhile, it can contact, prevent to rear with the excessive of oxygen during transfer to avoid blood
The inspection of phase generates interference.
