Abstract
The invention relates to a novel puncture needle. The novel puncture needle comprises a puncture needle main body 1 with an inner cavity, wherein the puncture needle main body 1 is a cuboid; an air inlet hole and a blood sample suction inlet, which are communicated with the inner cavity, are formed in the puncture needle main body 1; the air inlet hole and the blood sample suction inlet are elongated holes which are parallel to the axis of the puncture needle main body 1; the elongated holes are formed on two side faces of the puncture needle main body 1 and waist-shaped; and height distance is formed between the two elongated holes. The novel puncture needle has the advantage that on the premise that cross contamination is avoided and a cleaning effect is not influenced, the problem that a sample cannot be sucked or cannot be highly sucked is thoroughly solved.
Description
Technical field
The present invention relates to a kind of Novel puncture needle, relate in particular to a kind of Novel puncture needle that attracts sample to use when measuring for auto injection.
Background technology
The automatic puncturing pin that the existing instrument in market is used all is oblique tip, and length is fixed, when attracting sample, automatic puncturing can have two serious problems, when the first is thrust the lid of vacuum test tube at puncture needle, the rubber that has the site of puncture creeps in the puncture needle, cause inhaling sample and stop up or partly stop up, cause suction not enough less than sample or suction sample; It two is if the negative pressure deficiency of vacuum test tube can cause the specimen amount that gathers fewer; puncture needle can not be adjusted automatically because of height after thrusting; usually can cause to inhale less than sample or sample to attract deficiency, so that testing result is on the low side, thereby cause the doctor to the erroneous judgement of patient's state of an illness.
Summary of the invention
In order to address the above problem, to the invention provides a kind of can thoroughly the solution and inhale the Novel puncture needle that attracts the problems such as deficiency, obstruction less than sample or sample.
To achieve these goals, the invention provides a kind of Novel puncture needle, include the needle body 1 that is provided with inner chamber, which is provided with the air inlet hole and the blood sample suction inlet that communicate with inner chamber, the air inlet hole is the slotted hole parallel with the axis of needle body 1 with the blood sample suction inlet.
More optimizedly, needle body is rectangular parallelepiped, and slotted hole is positioned at the two sides of puncture needle.
More optimizedly, described slotted hole is kidney-shaped.
More optimizedly, described two slotted holes are provided with drop.
The invention has the beneficial effects as follows: original suction needle is when detecting sample, the situation that Lower result or results abnormity are often arranged, the problem that solves is to remeasure, and remeasure the increase of the reagent cost of both losing time also to cause, the designed hand sampling pin of this patent thoroughly solve inhale attract not enough problem less than sample or sample after, can save the regular hour to hospital laboratory, increase work efficiency and reduce unnecessary reagent waste.

Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
The present invention is a kind of Novel puncture needle, include the needle body 1 that is provided with inner chamber 3, described needle body 1 is provided with two air ins that communicate with inner chamber 3 and blood sample suction inlet, be slotted hole 2, needle body is rectangular parallelepiped, slotted hole 2 is positioned at the two sides of puncture needle, and slotted hole 2 is kidney-shaped, and two slotted holes 2 are provided with drop.When puncture needle thrusts the lid of vacuum test tube, owing to locate to be provided with two slotted holes 2 on the front end side, and two slotted holes 2 have drop, so suction inlet can not stopped up by rubber or half obstruction, do not worry puncture needle yet and after thrusting, cause suction to attract deficiency less than sample or sample because height can not automatically adjust.Do not causing cross pollution and do not affecting under the prerequisite of cleaning performance like this, thoroughly solving suction and attract problem not enough and that circular hole stops up less than sample solution or sample solution.
The above; it only is the specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
