Description

Reading duration control device

Technical field

The utility model relates to biologic applications technical field, particularly a kind of reading duration control device that detects.

background technology

Test strip is widely used in clinical detection diagnostic field.This checkout equipment is made up of sample reception district, product detection zone, adsorptive pads district and bottom deck assembly, when detection, add the sample that will detect to sample reception district, sample can flow to product detection zone under the suction of adsorptive pads, after flowing through product detection zone, absorbed by adsorptive pads, simultaneously, specific antigen or chemicals coated on the nitrocellulose filter of product detection zone react with sample, show result, people read corresponding test result by the reaction result on nitrocellulose filter.

Such pick-up unit only has the product detection zone being made up of the coated specific antigen of nitrocellulose filter or chemical substance mostly at present, sometimes because application of sample is few, concentration of specimens is high, the reason such as the stand-by period is inadequate after the strong or application of sample of adsorptive pads suction, cause the sample that will detect cannot flow through whole nitrocellulose filter, thereby make that testing result is inaccurate or testing result is invalid, cause testing result to have certain error.Some proving installation operation instructions are controlled at 5 minutes readings, and within 10 minutes, reading result is invalid.Therefore, while use for convenience of people, grasp the time of reading result, need a kind of reading duration control device.

utility model content

The utility model, for addressing the above problem, aims to provide one and has reading duration control window, and mark can read the reading time control device of testing result.

The technical solution of the utility model is: a kind of reading duration control device, comprise sample region of acceptance, product detection zone, reading duration control zone, adsorptive pads district and base plate, wherein, sample region of acceptance, product detection zone, reading duration control zone, adsorptive pads district are arranged on base plate successively, its feature is: the reading duration is controlled window using nitrocellulose filter as carrier, and reading the window's position is coated with antigen-antibody or chemical substance.

Described reading duration control device is for being test-strips, test board, prod, test card or test cup.

Under capillary effect, when sample is provided to reading duration control window, sample and coated material react, and form a mark.When this mark occurs, mean and can carry out interpretation to surveyed area testing result.

Compared with prior art, the beneficial effects of the utility model are:

1, increase a reading duration control window, can show the time of interpretation testing result.

2, easy to use, reading result is more intuitively relieved.

specific embodiment

In conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.

Embodiment mono-:

Visible in conjunction with Fig. 1, a kind of hCG test-strips with reading duration control window, comprise sample reception district 1, product detection zone 2, reading duration control zone 3, adsorptive pads district 4 and base plate 5, wherein, sample reception district 1, product detection zone 2, reading duration control zone 3, adsorptive pads district 4 are arranged on base plate 5 successively, wherein, the reading duration is controlled window 3 take nitrocellulose filter as carrier, and reading the window's position is coated with antigen-antibody or chemical substance.

There are a control line C line and a detection line T line in product detection zone.

Sample to be tested can be urine, serum or blood plasma.Using method is as Fig. 2, sample reception district 1 is immersed and within sample to be tested 5 seconds, takes out rear horizontal positioned, under the effect in adsorptive pads district 4, sample flows from sample reception district 1 to product detection zone 2, react with specific antibody coated in product detection zone 2, under capillary action, sample continues to flow to reading duration control zone 3, with antigen-antibody or chemical reaction coated in reading duration control zone nitrocellulose filter, form a mark, mark occurs that explanation sample to be tested flows through product detection zone 2 completely and reacted, we can carry out interpretation to surveyed area testing result.In conjunction with Fig. 3 to Fig. 5, testing result is described, when the detection line T in product detection zone 2 and nature controlling line C all develop the color, testing result is positive; When only nature controlling line C colour developing in product detection zone 2, illustrate that testing result is negative; When product detection zone only detection line T colour developing or detection line T and nature controlling line C all do not develop the color, illustrate that testing result is invalid, must again detect.

Embodiment bis-:

In conjunction with Fig. 6,7,8 visible, a kind of reading duration is controlled test board, prod, test card, comprise sample reception district 1, product detection zone 2, reading duration control zone 3, these regions are separated into three independent windows by shell, when detection, detected sample is dripped to sample reception district 1, under capillary action, sample flows to product detection zone 2 and reading duration control zone 3, also there is reaction and display mark in rear arrival reading duration control zone, sample flow multiparity product detection zone 23, mark occurs, illustrates that we can carry out interpretation to testing result.The interpretation of result is illustrated with embodiment mono-.

Embodiment tri-:

Visible in conjunction with Fig. 9, a hCG test cup with reading duration control window, comprises sample reception district 1, product detection zone 2, reading duration control zone 3, wherein, cup is as sample reception district 1, and product detection zone 2, reading duration control zone 3, adsorptive pads district 4 are arranged on base plate 5 successively.When detection, detected sample is joined to sample reception district 1, under capillary action, sample flows to product detection zone 2 and reading duration control zone 3, also there is reaction and display mark in rear arrival reading time control zone, sample flow multiparity product detection zone 23, mark occurs, illustrates that we can carry out interpretation to testing result.The interpretation of result is illustrated with embodiment mono-.

That more than disclose is only several embodiment of the present utility model; can not limit claim scope of the present utility model with this; one of ordinary skill in the art will appreciate that all or part of flow process that realizes above-described embodiment; by simple modification, equivalent variations, still belong to the protection domain of technical solutions of the utility model.
