The described solid shape of head that pierces through is for conical or pyramid.
As a kind of embodiment, described through hole is arranged on described hollow needle tube part and describedly solidly pierces through a connecting place.
As a kind of embodiment, two described through holes are arranged on described hollow needle tube part and describedly solidly pierce through a connecting place.
As a kind of embodiment, two described through holes are oppositely arranged.
As a kind of embodiment, described through hole center and the described solid distance piercing through the summit of head are 2.8 millimeters.
As a kind of embodiment, described through hole is circular hole, and this Circularhole diameter is 0.7 millimeter.
As a kind of embodiment, described through hole is square hole.
As a kind of embodiment, when the described solid head that pierces through is for time conical, the described solid circular cone angle piercing through head is 40 °.
As a kind of embodiment, described hollow needle tube part is distributed with at least 2 described through holes.
As a kind of embodiment, described hollow needle tube outer wall is cylindrical, or prismatic.
Compared with prior art, the utility model has following beneficial effect:
The utility model provides a kind of sampling probe, pierces through head, effectively can pierce through the rubber plug of sampling jar or blood collection tube, reduce the damage to bottle stopper portion while effectively piercing through by design taper shape or the solid of pyramid on sampling probe needle point.Pierce through head and hollow needle tube portion connection arranges through hole solid, effectively make use of whole bore section, accurately sample.The sidewall that through hole is located at sampling probe also can prevent the needle tubing when sampling probe pierces through rubber stopper from blocking.Complete pipetting and adding of blood sample or other liquid by described through hole, in robotization sampling application, robotization is sampled more accurately and efficient.
Accompanying drawing explanation
By reading the detailed description done non-limiting example with reference to the following drawings, other features, objects and advantages of the present utility model will become more obvious:
Fig. 1 is the solid sampling probe side view piercing through head of a kind of pyramid in optional embodiment;
Fig. 2 is the sampling probe side view that in optional embodiment, a kind of conical, massive pierces through head.
Embodiment
Below in conjunction with specific embodiment, the utility model is described in detail.Following examples will contribute to those skilled in the art and understand the utility model further, but not limit the utility model in any form.It should be pointed out that to those skilled in the art, without departing from the concept of the premise utility, some distortion and improvement can also be made.These all belong to protection domain of the present utility model.
According to a kind of sampling probe that the utility model provides, as depicted in figs. 1 and 2, comprise sampling probe body, described sampling probe body comprises hollow needle tube part and solidly pierces through head; One end of described hollow needle tube part is connected with the described solid head that pierces through;
Described hollow needle tube part is provided with through hole, and the endoporus of described hollow needle tube is by described through hole and ft connection;
The described solid shape of head that pierces through is for conical or pyramid.
Pyramid is solid pierces through that head is surperficial relative to bottle stopper has more vertical inserting surface, has and better pierces through effect.The conical solid head that pierces through then has relative to bottle stopper surface and cuts stress surface more uniformly, although stress surface can reduce more greatly the surface damage to bottle stopper, the circle caused thorn opening is not easily combined to cause with adjacent apertures and chapped.
Pierce through head by design taper shape or the solid of pyramid on sampling probe needle point, effectively can pierce through the rubber plug of sampling jar or blood collection tube, while effectively piercing through, reduce the damage to bottle stopper portion.
When the described solid head that pierces through is for time conical, as a kind of embodiment, the described solid circular cone angle piercing through head is 40 °, and when circular cone angle is too small, the solid head that pierces through can damage at the bottom of the bottle of sampling jar, and circular cone angle is excessive, cannot realize effectively piercing through to bottle stopper.
As a kind of embodiment, described through hole is arranged on described hollow needle tube part and describedly solidly pierces through a connecting place.Pierce through head and hollow needle tube portion connection arranges through hole solid, effectively make use of whole bore section, accurate sampling can be realized.If through hole and solid piercing through between head also leave one section of hollow needle tube part, then cannot draw or extrude the liquid in the hollow needle tube part of this part completely.The sidewall that through hole is located at sampling probe also can prevent the needle tubing when sampling probe pierces through rubber stopper from blocking.Complete pipetting and adding of blood sample or other liquid by described through hole, robotization is sampled more accurately and efficient.
As a kind of embodiment, two described through holes are arranged on described hollow needle tube part and describedly solidly pierce through a connecting place.
As a kind of embodiment, two described through holes are oppositely arranged.Two through holes be oppositely arranged are conducive to sampled blood or other liquid converges in the endoporus of described hollow needle tube part in being extracted.
As a kind of embodiment, described through hole center and the described solid distance piercing through the summit of head are 2.8 millimeters.
As a kind of embodiment, described through hole is circular hole, and this Circularhole diameter is 0.7 millimeter.
As a kind of embodiment, described through hole is square hole.
As a kind of embodiment, described hollow needle tube part is distributed with at least 2 described through holes.
As a kind of embodiment, described hollow needle tube outer wall is cylindrical, or prismatic.Prismatic hollow needle tube has better by force intensity, not easily loses in the process of piercing vials sampling.
The present embodiment may be used for blood sample or other fluid samples automatic collection, automatically transfer, automatically add in mark, automatically enter ml headspace bottle, in medical field efficient, accurate, to shift without block blood and provide convenience.
Above specific embodiment of the utility model is described.It is to be appreciated that the utility model is not limited to above-mentioned particular implementation, those skilled in the art can make various distortion or amendment within the scope of the claims, and this does not affect flesh and blood of the present utility model.
