Description
Technical field
The present invention relates to the liquid detecting technical field, particularly relate to a kind of liquid detection cup and preparation method thereof.
Background technology
Existing detection urine cup can be used for the joint-detection of entry, wall of cup is provided with the test paper clamp, this test paper clamp is provided with the test paper slot of placing test strips, and the test strips of test use is embedded in this test paper slot uses (being that the size of test strips and the size of test paper slot are complementary).When needs detect, give by detecting urine cup the patient who needs detection, allow it fill voluntarily urine, and the patient often has little understanding to structure, the principle of test strips, when filling urine, more than very likely urine can being installed to the MAX line, cause test strips to lose efficacy, can't complete detection.
In order to address the above problem, people are through research and development, this detection urine cup has been made to improvement, simultaneously set up transparent film layer in test strips in the face of liquid, this transparent film layer is covered in the test strips surface, thereby test strips is all covered, or cover major part, only stay bottom part sample application zone and directly contact with liquid.Therefore, while in detecting cup, liquid being housed, transparent film layer gets up the test strips top seal, and only staying sample application zone can directly contact with liquid, thereby can not make ELISA test strip invalid because liquid surpasses the MAX line, and then guarantees the effective loading of test strips, normal reaction.
But we find, in the chromatography process of being everlasting, the chromatography of liquid on test strips creeped may be subject to hindering and slack-offly even stopped, and causes normally being measured.
Summary of the invention
Based on this, the object of the invention is to overcome the defect of prior art, a kind of liquid detection cup is provided, adopt this detection cup to carry out the fluid sample detection, can guarantee carrying out smoothly of chromatography process, obtain and measure preferably effect.
For achieving the above object, the present invention takes following technical scheme:
A kind of liquid detection cup, comprise cup, test paper clamp and coverlay; Described test paper clamp is placed in cup, which is provided with for the test paper slot of placing test strips, and described coverlay covers test paper slot opening surface, sealing test paper slot inner space; This through hole is located on the coverlay corresponding to the test paper slot, the 1/30-1/2 that the length of this through hole centre distance test paper slot bottom margin is test paper slot height.
The present invention finds by research, simple coating epiphragma all or the test strips that covers of major part be unfavorable for the chromatography reaction, its reason is as follows: when the test strips loading has just started, there is certain gap between test strips surface and covering hyaline membrane, in test strips, gas is pushed by extraneous liquid, part can be discharged by this gap, but expand rapidly after the sample application zone water suction, the test strips sample application zone of coverlay and imbibition fits tightly, this gap is filled disappearance soon, in test strips, gas can't be discharged from here again, so far, test strips is completely sealed.And because the reaction of test strips chromatography is to occur by capillary action, as gaseous tension in test strips is greater than the pulling force that capillary action produces, if the capillary action pulling force can't overcome the resistance of γ-ray emission in test strips, the chromatography effect of test strips will be hindered, and can't normally carry out chromatography.
And, in the process of liquid chromatography on test strips, need to get over the label district from sample application zone, then show result in results display area, this process is undertaken by capillary pulling force.And once test strips inside is closed, the unnecessary gas remained in test strips can't be discharged, in the inner certain pressure intensity that forms of test strips, in the liquid process that chromatography is creeped on test strips, need opposing to live this internal pressure, once pressure is greater than the pulling force that capillary action produces, the chromatography effect will be hindered or can't normally be carried out.From such principle, the present invention has investigated multiple release mode, and, through a large amount of experimental studies, the final selection arranges by the bottom corresponding to test strips on coverlay the purpose that through hole reaches release.
The present invention also provides a kind of liquid detection cup, comprises cup, test paper clamp, test strips and coverlay; Described test paper clamp is placed in cup, which is provided with the test paper slot, and described test strips is positioned in described test paper slot, and described coverlay covers the detection faces of test strips, the sealing test strips; Described coverlay is provided with through hole, and this through hole is located on the coverlay corresponding to the test paper slot, the 1/30-1/2 that the length of this through hole centre distance test paper slot bottom margin is test paper slot height.
In embodiment, described through hole is located at corresponding on the coverlay below the test strips label pad therein.The present invention finds after deliberation, and the setting position of through hole is also very crucial.Higher when the position of through hole, as while being arranged on the thieving paper position corresponding to the test strips sample application zone other end, when in detecting cup, liquid levels is lower than this through hole, in test strips, unnecessary gas can be discharged by this through hole, and chromatography reacts and still can normally carry out; And in cup liquid level during higher than this through hole, in a flash incipient, form a gas column between the test strips that the coating epiphragma seals and coverlay, through hole is equivalent to the opening on this gas column, and at this moment, this gas column and outside liquid form huge pressure difference, the gas column internal gas pressure is far smaller than outside liquid pressure, in order to reach inside and outside pressure equilibrium, outside liquid will enter in this gas column by this through hole under the pressure of this pressure difference, and soak rapidly the test strips that full coating epiphragma seals, cause test strips invalid.
Below through hole being located at corresponding to test strips bottom label pad, on the coverlay at (corresponding to the sample application zone place), through hole is in the bottom of test strips.Liquid is in test strips sample application zone loading process, after the sample application zone water suction, expand gradually, but also not with cover in the situation that hyaline membrane fits fully, there is gap in the test strips sample application zone with covering between hyaline membrane, in test strips, gas can be by this gap and through hole discharge; And, when sample application zone expand into fully laminating and covers hyaline membrane, gap is sealed, the gas in test strips can't be discharged from here again.When liquid is come lead to the hole site, the yet imbibition gradually of the test strips of through hole part, also do not expanding into firmly hyaline membrane of laminating fully, and in the situation that through hole is not blocked fully, in test strips, gas still can be discharged from this through hole.When in cup, liquid level is lower than the through hole position, the Exhaust Gas naked eyes are invisible; When in cup, liquid level is higher than through hole place height, liquid is discharged macroscopic bubble by through hole.When the test strips of through hole continues to expand into when coverlay is lived in laminating fully, gas can not be discharged from through hole again, and now, test strips is in complete sealing state, and test strips will be carried out chromatography by capillary force.At this moment may still have a certain amount of gas in test strips, but, after place that can exhaust by above-mentioned two places discharges, the interior pressure of test strips is moderate, the chromatography effect can be carried out smoothly.
The reasonable setting of this through hole can be assisted the discharge of gas in test strips, after the test strips at coverlay bottom margin place expands, exhausr port is blocked, unnecessary gas makes in test strips when can't be discharged from here again, gas also can be discharged by through hole, until expanding, test strips blocks through hole, thereby extended gas efflux time in test strips, reduced pressure in test strips, guaranteed that the chromatography effect normally carries out.
Therein in embodiment, the 1/6-5/6 that described coverlay bottom edge is sample application zone length on test strips apart from the length of test strips bottom margin.And the bottom edge reference position of coverlay and through hole setting position are very crucial to the quality of chromatography effect, allow coverlay cover a part of sample application zone, rather than test strips is covered fully or only started to cover by the label pad district, purpose is to make liquid that a buffer action be arranged when the test strips loading, liquid can get over labeling pad by the chromatography effect, then shows result in viewing area.As test strips is covered fully, be difficult to the loading that assures success; As coverlay only overlay marks pad district and above part, the sample application zone of steeping in liquid is oversize, and liquid may directly be broken through label pad, rushes the sample phenomenon, causes the chromatography reaction normally not carry out.
Therein in embodiment, the distance of the distance of described through hole center and test strips bottom margin and through hole center and label pad lower limb is than being 7:1-3:1.When through hole is positioned at this height, inside and outside pressure difference the best of test strips, can obtain best chromatography effect.
Therein in embodiment, the 1/3-1/2 that the diameter of described through hole or the length of side are the test strips width.As through hole is too large, liquid easily directly enters in test strips by this through hole, and through hole does not have scavenging action, is equivalent to coverlay from through hole, and through hole performs practically no function.And if the through hole setting is too little, when liquid on test strips during loading, sample application zone expands rapidly, soon through hole is sealed, the gas flow of discharging from this through hole is quite few, be unfavorable for the release of pressure in test strips, the gas that remains in test strips inside is more, is unfavorable for that on test strips, the chromatography sufficient reacting carries out.Therefore, through after experiment repeatedly, while determining the 1/3-1/2 that diameter or the length of side when through hole are the test strips width, best results.
In embodiment, described coverlay is hyaline membrane therein; Described test paper clamp circumferentially arranges along cup, and described test paper slot is located at the test paper clamp towards cup one side, and described cup is transparent cup, is convenient to observe reading result.
In embodiment, described test paper clamp is connected with cup is detachable therein.Production, easy to assembly.
In embodiment, also comprise bowl cover, described bowl cover and cup threaded engagement therein; Be provided with O-ring seal at the bottom of described bowl cover.Coordinate the use of bowl cover, can avoid detecting the problem of fluid seepage in cup.The use of O-ring seal, improved the leakproofness between cup and bowl cover.Described O-ring seal is preferably made by silica gel.Silica gel material is difficult for aging, good leak tightness, and it is inert material, can not react with the liquid detected in cup, affects testing result.And, when tested liquid need to be sent to secondary detection, this is provided with and is beneficial to sealing and preserves a liquid in cup, avoid liquid in the process of transporting owing to being inverted, tilting to leak, affect censorship, contaminated environment.
The present invention also provides a kind of method for making of liquid detection cup, comprises the following steps:
1) with the detection faces of test strips outside the test paper slot, test strips is positioned in the test paper slot on the test paper clamp;
2) be covered in above-mentioned ELISA test strip face with the coverlay that is provided with through hole, test strips is sealed in the confined space that coverlay and test paper slot form, and the position that makes described through hole is corresponding to the following part of test strips label pad;
The test strips that 3) will assemble by above-mentioned steps, coverlay and test paper clamp are put into the cup that detects cup, obtain.
