Description
Technical field
The present invention relates to vitro detection technical field, particularly relate to a kind of trace sample Test paper.
Background technology
Along with progress and the growth in the living standard of society, people more and more pay close attention to self health, more and more pay attention to the early diagnosis of disease and screening.Therefore, more detection meanss of more accurately diagnosing easily are needed to meet this requirement.Diagnose test paper, as the detection means that a kind of extensively detected personnel, medical worker and users accept extensively, 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, compare with Standard colour board, just can obtain result of laboratory test.Because it has broken away from valuable instrument and equipment, greatly reduce laboratory fee use, the dark welcome by vast health service unit, is significant to the medical test of the vast rural area of China and industrial and mineral grass-roots unit.
The development of China in 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.In the sensitivity, storage life of test paper, had new progress, end item reaches international most advanced level.But, the current the most scabrous problem of fast diagnose test paper is that the sample collection amount needed for test paper is large, especially blood, due to the very easily blood coagulation of finger tip blood, finger tip blood cannot be applied detect as sample, need to gather venous blood, but also need the sample size of at least 20ul, thus the collection of blood sample needs professional to operate, and is 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 required is large, cause the problem of sample collection inconvenience, provide one finger tip blood to be detection sample, and only need trace sample can carry out the trace sample Test paper detected.
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 closely connected successively sample pad, pad, reaction film and absorption pad, and described reaction film is provided with detection zone and quality control region.
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 extended to outside stabilizing solution reservoir and takes off ear.
Preferably, described stabilizing solution reservoir built with blood stabilizing solution, the edta buffer liquid of described blood stabilizing solution to be pH be 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 a U trap that anticoagulant is 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, described anticoagulant is the heparin solution of 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 is communicated with by fluid port with negative pressure cabin.
Furtherly, space is provided with between described sample pad and haemocyte filter membrane.
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 arranging anti-freezing sample tube in sample collecting device, significantly can reduce the blood coagulation phenomenon of blood sample, reducing the loss of blood plasma, thus the collection capacity of blood sample can be reduced.Sample pad arranges stabilizing solution reservoir, blood sample is added drop-wise to Absorbable organic halogens and dilute blood sample in stabilizing solution reservoir, further minimizing blood coagulation phenomenon, thus 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 arranging negative pressure cabin, the liquid in reservoir can be made to flow in sample pad more completely, rapidly, improving the utilization factor of sample.The pressure of negative pressure cabin is 10-300Pa, has both made liquid from reservoir, can arrive sample pad fast, can avoid again causing haemocyte broken 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, one deck anticoagulant film can be formed at siphonal inwall, by anticoagulant film to anticoagulation blood, make the structure of sample collecting device simple, easy and simple to handle by this setting.The present invention is by arranging sample collecting device and reservoir and negative pressure cabin, and can realize only gathering micro-fingertip blood sample and accurately can detect disease, sample collection amount can be less than 1 μ L.
