A hemocyte filter membrane is arranged on a sample pad, a stabilizing solution storage tank is arranged on the hemocyte filter membrane, and the sample collector comprises a negative pressure piece and an anti-coagulation sample pipe. According to the trace sample test paper, the anti-coagulation sample pipe is arranged in the sample collector, and thus the blood coagulation of a blood sample can be remarkably reduced, the loss of blood plasma is reduced, and thus the collecting quantity of a blood sample can be reduced. the stabilizing solution storage tank is arranged on the sample pad, the blood sample is dropwise added in the stabilizing solution storage tank so that the blood sample can be stabilized and diluted, thus the coagulation is reduced, and thus blood plasma in the blood sample is fully utilized, blood in fingertip can be used as a detection sample of rapid detection test paper, and the sample collecting quantity can be less than 1 mu L. By arranging a negative pressure bin, a liquid in the storage tank can completely and rapidly flow in the sample pad, and thus the utilization rate of the sample is increased.
Description
Technical field
The present invention relates to vitro detection technical field, relate in particular to a kind of trace sample Test paper.
Background technology
Along with social progress and growth in the living standard, people more and more pay close attention to the health of self, and the early diagnosis of disease and screening are more and more paid attention to.Therefore, need more detection meanss of more accurately diagnosing easily to meet this requirement.Diagnose test paper, the detection means of accepting extensively as a kind of extensively detected personnel, medical worker and users, it possesses quick and easy, lower-price characteristic, is more and more subject to everybody attention.
Fast diagnose test paper is a kind of solid reagent that recent two decades grows up.It has the advantages such as simple and easy, quick, accurate and inexpensive.Be the most simply with a test paper, soak sample, with Standard colour board comparison, just can obtain result of laboratory test.Because it has broken away from valuable instrument and equipment, greatly reduce laboratory fee use, be deeply subject to the welcome of vast health service unit, the medical test of the vast rural area of China and industrial and mineral grass-roots unit is significant.
The development of China aspect fast diagnose test paper is very fast, and kind aspect is not second to US and European.As medicaments insensitive test paper, urea nitrogen quantitative test paper etc., existing many decades of application; Multinomial associating test paper (as eight, seven, six etc.) is also succeeded in developing.Aspect the sensitivity of test paper, storage life, having new progress, end item has reached international most advanced level.But, the current the most scabrous problem of fast diagnose test paper is that the required sample collection amount of test paper is large, especially blood, due to the very easily blood coagulation of finger tip blood, cannot apply finger tip blood and detect as sample, need to gather venous blood, but also need at least sample size of 20ul, thereby the collection of blood sample needs professional to operate, be difficult to spread in users' hand.
Summary of the invention
The present invention is directed to existing quick detection test paper cannot apply finger tip blood and make sample, and the sample size requiring is large, cause the problem of sample collection inconvenience, it can finger tip blood be detection sample that one is provided, and the trace sample Test paper that only needs trace sample to detect.
For achieving the above object, the present invention by the following technical solutions,
A kind of trace sample Test paper, comprise a test paper body and sample collection dress device, described test paper body comprises a base plate, and is located on base plate and tight connected sample pad, pad, reaction film and absorption pad successively, and described reaction film is provided with detection zone and Quality Control district.
Described sample pad is provided with haemocyte filter membrane, and described haemocyte filter membrane is provided with a stabilizing solution reservoir, and the groove face of described stabilizing solution reservoir is provided with a groove lid, and the bottom land of described stabilizing solution reservoir is provided with a fluid port, and described fluid port is provided with a sealed piece.
Furtherly, described groove lid is a groove face film, and described groove face film is provided with a groove face film and takes off ear; Described sealed piece is a sealed membrane, and the surrounding sealing of described sealed membrane is pasted on the surrounding of fluid port, and sealed membrane is provided with a sealed membrane extending to outside stabilizing solution reservoir and takes off ear.
Preferably, in described stabilizing solution reservoir, blood stabilizing solution is housed, described blood stabilizing solution is that pH is the edta buffer liquid of 6.8-7.6.
Described sample collecting device comprises a negative pressure part and an anti-freezing sample tube, and one end of described anti-freezing sample tube is communicated with negative pressure part.
Furtherly, described anti-freezing sample tube is one the U trap of anticoagulant to be housed, and described siphonal one end is communicated with negative pressure part, and the siphonal other end is provided with a tube sealing film.
Preferably, the heparin solution that described anticoagulant is 0.1-1.5wt%.
Described test paper body also comprises a negative pressure cabin, and described base plate, sample pad, pad, reaction film, absorption pad and haemocyte filter membrane are located in negative pressure cabin, and stabilizing solution reservoir is located on negative pressure cabin, and stabilizing solution reservoir can be communicated with by fluid port with negative pressure cabin.
Furtherly, between described sample pad and haemocyte filter membrane, be provided with space.
Furtherly, the pressure of described negative pressure cabin is 10-300Pa.
Compared with prior art, the invention has the beneficial effects as follows: the present invention, by anti-freezing sample tube is set in sample collecting device, can significantly reduce the blood coagulation phenomenon of blood sample, reduce the loss of blood plasma, thereby can reduce the collection capacity of blood sample.Stabilizing solution reservoir is set in sample pad, blood sample is added drop-wise in stabilizing solution reservoir and can be stablized and dilute blood sample, further reduce blood coagulation phenomenon, thereby the blood plasma in blood sample is utilized more fully, make finger tip blood can be used as the detection sample of quick detection test paper.By negative pressure cabin is set, can make the liquid in reservoir flow in sample pad more completely, rapidly, improve the utilization factor of sample.The pressure of negative pressure cabin is 10-300Pa, has both made liquid can from reservoir, arrive fast sample pad, can avoid again causing haemocyte fragmentation because pressure is excessive, disturbs final testing result.The U trap that anticoagulant is housed is set in sample collecting device, before sample of blood, drawn, the anticoagulant in U trap is extruded, can form one deck anticoagulant film at siphonal inwall, by anticoagulant film, blood is played to anticoagulation, make the simple in structure, easy and simple to handle of sample collecting device by this setting.The present invention, by sample collecting device and reservoir and negative pressure cabin are set, can realize and only need the micro-fingertip blood sample of collection can accurately detect disease, and sample collection amount can be less than 1 μ L.
