Description

CRP detection devices

Technical field

The present invention relates to medical instrument, is specially a kind of CRP detection devices.

Background technology

In cellanalyzer, existing CRP (viral infection) measuring device is divided into two kinds：

One kind is to add hemolytic agent and blood sample by sampling needle, such a adding set, because using a sampling needle repeatedly into Row reagent gathers and blood specimen collection, have impact on the adding speed of reagent and the detection rates of CRP.

Another sampling needle only carries out sample collection and blood specimen collection to one of which reagent, while molten to one of which Blood agent has pre- addition, accelerates CRP reagent sample adding speeds, while improve CRP detection rates；But the preheating of this device All the time some reagent is preserved in mechanism, while preheats the hot environment that mechanism remains at 37 °, detects and fills in CRP Put long-time when not in use, the pilot scale agent of preheating mechanism is apt to deteriorate after long-time high-temperature storage, and inner cavity cleaning is difficult；To protect It is accurate to demonstrate,prove testing result, it will usually first the old reagent preheated in mechanism is rinsed well using a large amount of reagents, thus, is added The usage amount of single CRP test agents, adds testing cost.

Auspicious 5390CRP detection devices are such as stepped, there is disadvantage mentioned above, i.e.,：

Reagent in preheating apparatus remains at 37 °, when not in use for a long time, easily goes bad, and cleaning is difficult, And need to clean it using substantial amounts of reagent before detecting every time, add single sample testing cost.

The content of the invention

In view of the deficiencies of the prior art, the technical problems to be solved by the invention are to propose a kind of various reagents that reduce to disappear Consumption, the CRP detection devices for reducing testing cost.

The CRP detection devices of above-mentioned technical problem can be solved, its technical solution includes the reaction tank set based on engine base With according to pond, the reaction tank is equipped with sampling needle entry port and is communicated with reagent adding tube, described to be equipped with light according to pond Learn testing agency and be communicated with cleaning pipe, reaction tank and (realize reaction tank and according between pond according to mixed flow tube is communicated between pond Fluid exchange), except that the engine base is equipped with by the heat transfer preheating reaction tank and heating arrangements according to pond, institute Engine base is stated to be made of the metal material of good heat-transfer.

It is with the technical solution for avoiding reagent contamination from taking to improve addition efficiency：The reaction tank according to pond with being arranged on On same vertical plane, described to be arranged on according to pond below the left or right side of reaction tank, the axis of reaction tank is vertical direction, is contrasted The axis in pond is inclined to the axis of reaction tank to the left or to the right；The reagent adding tube is connected with mixed flow tube with identical height The lower part of reaction tank and with according on the opposite side in pond, the mixed flow tube and cleaning pipe connection are contrasted in opposite with reaction tank On the side of pond and mixed flow tube connection height be more than cleaning pipe connection height.

In said structure, the reagent adding tube and mixed flow tube are main to consider processing with identical height connected reaction pond It is convenient, while when cleaning reaction tank, the reagent that liquid is easier to add reagent on pipe addition cleans up, and reduces and intersects dirt Dye；The connection of the mixed flow tube is highly more than cleaning pipe, its main cause is to consider to eliminate problem according to bubble in pond, from lower past Upper plus cleaning liquid, can effectively exclude to contrast the bubble in pond, reduce interference of the bubble to test result, ensure test knot The accuracy of fruit.

The axis deviation according to pond in reaction tank axis optimized angle between 20 °~40 °.

The axis deviation according to pond is 30 ° in the best angle of reaction tank axis.

Conventionally, the sampling needle entry port is arranged on the upper port of reaction tank.

Conventionally, the optical de-tection means are in the upper port according to pond.

Beneficial effects of the present invention：

1st, in CRP structure of the detecting device of the present invention, since reaction tank side is provided with reagent inlet, can be added by reagent Pipe is added to add reagent, the addition efficiency of reagent and blood sample when improving CRP detections, because reducing sampling needle takes reagent Number, can be to avoid reagent cross contamination.

2nd, in structure of the present invention, heating arrangements are only heated to reaction tank and according to pond, and CRP detection reagents are added to reaction tank Before remain room temperature, meet reagent preservation condition, though for a long time without using instrument carry out CRP data tests, will not be right CRP detection reagents are heated, and reduce amount of reagent, effectively reduce single CRP testing costs.
