Abstract
The invention provides a sample injection needle for a chemiluminescence immunoassay analyzer. The sample injection needle comprises a sample injection needle main body, a needle body and a mounting plate, and is characterized by further comprising a liquid level sensor, wherein the liquid level sensor, the needle body and the mounting plate are positioned on the sample injection needle main body. On the basis of the conventional sample injection needle, a liquid level sensor assembly is introduced and is used for judging a relative position relation between the liquid level and a needle head, so that the moment for executing suction or removal of liquid is determined; a coagulation induction module is used for judging whether a needle hole is blocked in a liquid suction process or not so as to determine whether a coagulation phenomenon exists or not. By the introduction of the module, the working efficiency of the sample injection needle is greatly improved, so that the overall use efficiency of the sample injection needle applied to the chemiluminescence immunoassay analyzer is improved.
Description
Technical field
The present invention relates to technical field of immunoassay, be specifically related to a kind of sample needle for chemical illumination immunity analysis instrument.
Background technology
Chemical illumination immunity analysis instrument is the instrument for measuring chemical composition in blood or other body fluid, this analyser the steps such as the sampling in analytic process, reagent adding, detection are integrated in one robotization realize, be widely used at situation of all-level hospitals, epidemic prevention station at present.Sample arm is one of critical piece in this analyser, and the process completing reagent for driving sample needle and add, has the function that opposite planar carries out being elevated and selecting dress.And be positioned at the sample needle of sample arm outer rim, be responsible for going deep into vessel and perform application of sample action, because immunoassay process needs accurately to control application of sample action, therefore requirements at the higher level are proposed to the performance of sample needle.In addition, owing to may relate to the liquid that blood, tissue fluid etc. can condense in application of sample process, therefore the problem of blood coagulation obstruction pin hole also happens occasionally.
Summary of the invention
The present invention is intended to the technological deficiency for prior art, a kind of sample needle for chemical illumination immunity analysis instrument is provided, realize in application of sample process, judging rapidly that the phenomenon of pin hole is blocked in blood coagulation, correctly, fast can perform imbibition action according to the position of liquid level simultaneously.
For realizing above technical purpose, the present invention by the following technical solutions:
For a sample needle for chemical illumination immunity analysis instrument, comprise sample needle main body, needle body, installing plate, characterized by further comprising liquid level sensor, wherein liquid level sensor, needle body and installing plate are positioned in sample needle main body.
Preferably, also comprise blood coagulation induction module, described blood coagulation induction module is positioned in sample needle main body.
Preferably, described needle body is positioned at sample needle body rim.
Preferably, described installing plate is hollow cylinder.
Preferably, described liquid level sensor is photoelectric liquid level sensor.
The present invention introduces level sensor assembly on the basis of traditional sample needle, and for judging the relative position relation of liquid level and syringe needle, thus Predicated execution is drawn or got rid of the opportunity of liquid; Whether blood coagulation induction module, exist the situation blocking pin hole in the process by judgement imbitition and determine whether there is blood coagulation phenomenon.The introducing of above-mentioned module improves the work efficiency of sample needle greatly, and then improves complete machine service efficiency when being applied to chemical illumination immunity analysis instrument.
