Specific embodiment
The technical scheme in the embodiment of the present invention will be clearly and completely described below, it is clear that described implementation
Example is only a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, this area is common
All other embodiment that technical staff is obtained under the premise of creative work is not made, belongs to the model of present invention protection
Enclose.
Fig. 1 and Fig. 2 is referred to, the embodiment of the present invention includes：
A kind of blood lancet device, including puncture needle 1, Paracentesis needle holder 2, extension tube 3 and blood sampling needle part, the blood sampling needle part is
To insert blood sampling pipe end.The puncture needle 1 is fixed on the Paracentesis needle holder 2, the other end connection extension tube of the Paracentesis needle holder 2
3 one end.The blood sampling needle part includes extension base 4, rubber cushion 5, cannula needle 6, intubation needle stand 7 and hand-held sheath 8.It is described to prolong
The other end of long tube 3 is connected with one end of the extension base 4 on the blood sampling needle part.The other end dress of the extension base 4
Equipped with rubber cushion 5, the rubber cushion 5 can make the inner chamber of the extension base 4 as sealing state.Assembled on the extension base 4
Rubber cushion 5 is inserted into the inner chamber of the hand-held sheath 8, and the rubber cushion 5 is assembled between extension base 4 and hand-held sheath 8 and quilt
It is fixed, while ensureing that sealing is not connected extension base 4 each other with hand-held sheath 8.In the rubber cushion 5 and the hand-held sheath 8
Inner chamber in form a cavity, the cavity can accommodate the intubation needle stand 7 in the axial direction of the hand-held sheath slidably simultaneously
There is a step 81 to ensure that the intubation needle stand 7 can not be skidded off from the hand-held sheath 8, the cannula needle 6 passes through the intubation
Needle stand 7, one end of the cannula needle 6 faces the rubber cushion 5.Expose simultaneously from the intubation needle stand 7 at the two ends of the cannula needle 6
Interfixed by glue and be integrated.The cannula needle 6 is more than the rubber cushion near the exposed length of the bared end of the rubber cushion 5
5 thickness, the exposed length of the other end of the cannula needle 6 is the length that can pierce into heparin tube 9.The cannula needle 6 with it is described
Frictional force between rubber cushion 5 is less than the frictional force between the cannula needle 6 and heparin tube 9.
The course of work of the blood lancet device is：When using, the handle of hand-held puncture needle 1 carries out conventional puncture, it is seen that
Latter of blood back is held to stop and holds sheath 8, and another hand is inserted by a heparin tube 9 from the open end of hand-held sheath 8.When insertion is adopted
When blood vessel 9 is taken a blood sample, heparin tube 9 promotes cannula needle 6 and intubation needle stand 7 to the Slideslip of rubber cushion 5 one, promotes cannula needle 6 to penetrate
Rubber cushion 5, now intubation needle stand 7 stops that stopping is slided by rubber cushion 5, and heparin tube 9 is continued into, and the other end of cannula needle 6 is pierced through
Heparin tube 9, blood sampling passage is connected completely is taken a blood sample, as shown in Figure 2.Blood sampling is finished, and when extracting heparin tube 9, heparin tube 9 drives
Cannula needle 6 and intubation needle stand 7 are slided to the open end of hand-held sheath 8, when intubation needle stand 7 slides into the step 81 of hand-held sheath 8
When stop slide, cannula needle 6 from blood sampling passage withdraw from, rubber cushion 5 blood sampling passage seal, prevent blood leakage, and heparin tube 9 after
It is continuous to extract so as to depart from cannula needle 6 and intubation needle stand 7, complete blood collection procedure.
Embodiments of the invention are the foregoing is only, the scope of the claims of the invention is not thereby limited, it is every to utilize this hair
