Abstract
The utility model relates to a D-dimer tester, which comprises a rotating sampling arm, a reagent part, a testing part, a double-barreled pump, a liquid collection cylinder, a sample part, a micro-injection pump and a needle washing part, wherein the sample part, the reagent part, the testing part and the needle washing part are arranged on the same work platform. The D-dimer tester has the advantages that: the operation is easy, the risk of cross-contamination is avoided, the testing is stable, the precision is higher, the demand of the market is met, and the mistakes of manual operation can be avoided by an unique warning function of the tester, and thus the accuracy of test results of a hospital is ensured.
Description
Technical field
The utility model belongs to medical instruments field, is specifically related to a kind of D-dimer tester.
Background technology
(D-Dimer is to hand over the special catabolite of sign fibrin D-D) to the D-dimer, its generation or increase the activation that has reflected blood coagulation and fibrinolytic system.The D-dimer is a kind of dimer compound that the body coagulation process may produce, generally do not produce in the normal body or generation few.In whole blood or blood plasma, adopt antibody can detect D-D content at an easy rate to D-D.The D-dimer mainly reflects the fibrinolysis function.Increase or the positive is shown in Secondary cases fibrinolysis hyperfunction, like hypercoagulative state, disseminated intravascular coagulation, kidney trouble, organ transplant rejection, thromboembolism treatment etc.In recent years, along with methodological continuous progress, set up the multiple responsive simply fast method that is applicable to emergency treatment, the clinical practice that D-D detects more and more widely.Big quantity research confirmed D-D get rid of that the diagnosis lower-limb deep veins thrombus forms and pulmonary embolism in using value, with it as one of first-selected screening index.Recently, the application that detects of D-D is deep into disseminated intravascular coagulation, angiocardiopathy, HRT, malignant tumour and anticoagulant therapy field the sixth of the twelve Earthly Branches.At present, in D-dimer field of test instrument, there is full automatic D-dimer tester that automanual D-dimer tester is also arranged; The implementation method of full automatic D-dimer tester is to adopt fixed partition, and then injects blood sample and test agent, because subregion is more; For accomplishing whole automatic testing process, cause a plurality of XYZ kinematic systems to be intersected and frequently run on each separation fixed interval, so also make the whole instrument test speed slow; And whole device is huge loaded down with trivial details, and measuring accuracy is not high, but also is not easy control; The high maintenance difficulty of failure rate is big, and cost is higher.Semi-automatic D-dimer tester need expend bigger human cost, and can not the adaptive testing sample size many and test duration such as lack at requirement.Full-automatic D-dimer tester is suitable for the test of great amount of samples, though semi-automatic D-dimer tester is fit to the test of small amount of sample, but expends more manpower and time.
The utility model content
The utility model provides a kind of automatic and artificial D-dimer tester that combines; This instrument can once be accomplished four project testings of a sample automatically; And native system contains the Computerized intelligent device, can warn experimental result, and then open four project testings of next sample by manual work; Realized that promptly robotization avoided manually-operated arbitrariness again, improved the efficient and the quality of test.
For realizing above-mentioned purpose, adopt following technical scheme:
A kind of D-dimer tester; Comprise sample arm, reagent position, test position, wash pin position, two-tube pump, liquid cylinder, sample position, micro-injection pump; The turning radius of said rotation sample arm can cover sample position, reagent position, wash the pin position, and said sample position and reagent position are along distributing symmetrically on the circumference of rotation sample arm rotation.Workbench wash the pin position below be connected with liquid cylinder.The below of rotation sample arm is connected with micro-injection pump and two-tube pump.
The utility model is simple in structure, compact, processing ease; Avoided the risk of cross pollution; The test result consistance is strong, stable, precision is higher, and its intelligent prompt function can avoid error of manual operation, thereby guarantees the correctness of the test result of hospital.
Description of drawings
According to embodiment and accompanying drawing the utility model is done further explain below.
Fig. 1 is the utility model general structure synoptic diagram;
Among the figure:
1, rotation sample arm; 2, reagent position; 3, test position; 4, two-tube pump; 5, liquid cylinder; 6, micro-injection pump; 7, sample position; 8, wash the pin position.
Embodiment
As shown in Figure 1; Provided a specific embodiment of the utility model; Among the figure; Reagent position 2, test position 3, sample position 7 be installed on same workbench, wash pin position 8, rotation sample arm 1, the turning radius of said rotation sample arm 1 can cover sample position 7, reagent position 2, test position 3, said sample position 7, reagent position 2, test position 3, washes on the circumference that rotates along rotation sample arms 1 pin position 8 and distributes symmetrically.For making the whole instrument orderly operation that links up, be provided with two-tube pump 4, liquid cylinder 5, micro-injection pump 6 in the instrument.
The course of work of whole instrument is following: but dynamic and control device make rotation sample arm 1 left-right rotation and drive sample needle and move up and down in the utility model, and rotation sample arm 1 can cover sample position 7, reagent position 2, test position 3 and wash pin position 8 through rotating.Rotation sample arm 1 is in the reagent pipe of 2 extraction different reagent to sample positions 7, reagent position, and the amount of injection reagent is controlled by micro-injection pump 6, and is washing the 8 completion conversion cleanings of pin position, and the liquid of cleaning flows into liquid cylinder 5, avoids the cross pollution of reagent.After accomplishing reagents loaded; Rotation sample arm 1 cooperatively interacts with two-tube pump 4 and is written into the sample in the sample position 7 in the test position 3; Accomplish sample and rotate sample arm 1 after being written into and accomplish conversion and clean washing pin position 8, tested by test macro, test back intelligent apparatus can send information.Whole instrument with interpolation reagent, to wash pin, test, each functional module of intelligent prompt integrated; Make whole test process continuous automatically, avoided the cross pollution of sample and reagent, also have one-piece construction and layout is simple; Operation is quick, and test result high conformity and precision are high.
Claims (3)
1. D-dimer tester; Comprise sample arm, reagent position, test position, two-tube pump, liquid cylinder, sample position, micro-injection pump and wash the pin position; It is characterized in that: reagent position, test position, sample position are installed on same workbench, wash the pin position, rotate sample arm; The turning radius of said rotation sample arm can cover sample position, reagent position, test position, wash the pin position, said sample position, reagent position, test position, washes on the circumference that rotates along the rotation sample arm pin position and distributes symmetrically.
