Abstract
The invention relates to a novel hand-operated sample introduction needle which comprises a main body of the sample introduction needle. A hollow chamber is arranged inside the main body of the sample introduction needle. The bottom of the needle is a round end, wherein a suction inlet is provided at the position of the circle center of the bottom, and a cross groove is disposed at the position of the diameter of the bottom, and the width of the cross groove is the same as the diameter of the suction inlet. The novel hand-operated sample introduction needle is advantageous in that the problem of the incapability of sucking up a sample or insufficient of the sucked sample is thoroughly solved.
Description
Technical field
The present invention relates to a kind of novel manual sample introduction needle, relate in particular to and a kind ofly be installed on the five classification blood cell appearance that the beautiful really bio tech ltd in Jiangsu produces the hand sampling pin that attracts blood preparation to use when being used for manually measuring.
Background technology
The hand sampling pin that the existing instrument in market is used all is round end or tack, and what adorn at ordinary times that sample uses all is anticoagulant tube or sub warhead, because of the bottom of anticoagulant tube is circular; The bottom of sub warhead is sharp, adds that doing the general of hand sampling all is the fewer sample of specimen amount, so when manually inhaling appearance; Usually anticoagulant tube or sub warhead are withstood suction needle and draw sample; Can cause suction to attract deficiency like this, cause testing result on the low side, cause the erroneous judgement of doctor patient's state of an illness less than sample or sample.
Summary of the invention
In order to address the above problem, the invention provides a kind of problem novel manual sample introduction needle that can thoroughly solve suction less than sample or sample attraction deficiency.
To achieve these goals; The present invention provides a kind of novel manual sample introduction needle, comprises sample introduction needle main body 1, is provided with hollow cavity 2 in the sample introduction needle main body 1; And its bottom is a round end 3; The bottom home position has a suction inlet 4, and its diametrical position offers translot 5 one in the bottom, and translot 5 length are identical with suction inlet 4 diameters.
Like this, do not causing cross pollution and do not influencing under the prerequisite of cleaning performance, thoroughly solving and inhale less than sample or the not enough problem of sample attraction.
The beneficial effect of hand sampling pin of the present invention is: original suction needle is when detecting sample; The situation that the on the low side or results abnormity of result is often arranged; The problem of solution is to remeasure, and also causes the increase of reagent cost and remeasure both to lose time, and uses hand sampling pin of the present invention after thoroughly solving the problem of inhaling less than sample or sample attraction deficiency; 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 set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
The present invention is a kind of novel manual sample introduction needle; Comprise sample introduction needle main body 1, be provided with hollow cavity 2 in the sample introduction needle main body 1, and its bottom is a round end 3; The bottom home position has a suction inlet 4; Its diametrical position offers translot 5 one in the bottom, and translot 5 length are identical with suction inlet 4 diameters, and sample solution can be sucked into the hollow cavity 2 from the suction inlet on the bottom round end 34; Owing to have translot 5 on the centre position of bottom round end 3; So no matter the anticoagulant tube of splendid attire sample solution bottom is that circle or sub warhead can both leave certain space, do not causing cross pollution and do not influencing under the prerequisite of cleaning performance like this, thoroughly solve to inhale and attract not enough problem less than sample solution or sample solution.
The above; Be merely embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any those of ordinary skill in the art are in the technical scope that the present invention disclosed, and 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.
