Description

A kind of dry multipurpose urine test paper

(1) technical field:

The utility model relates to a kind of in-vitro diagnosis test strips, particularly a kind of dry multipurpose urine test paper.

(2) background technology:

Utilize the dry multipurpose urine test paper bar can be to pH in the urine, cholerythrin, urobilinogen, nitrite, protein, glucose, red blood cell, proportion, vitamin C, ketoboidies, projects such as leucocyte are carried out quick test and are judged health and fitness information for doctor or patient individual, the dry type urine test paper of being sold on the existing market is generally by substrate, pressure sensitive adhesive double coated and the embedding subsides of pasting usefulness are packed in the pH that an on-chip end is arranged in order, blank block and other project such as cholerythrin, urobilinogen, red blood cell, protein, nitrite, vitamin C, glucose, leucocyte, proportion, the indicator paper block of ketoboidies etc. combines, using method is generally test strips is immersed 1～2 second in the body fluid to be measured, when test strips is taken out from the body fluid that soaks unnecessary test solution is sopped up or wipes off, level holds, and puts into the instrument colorimetric or obtains a result at official hour and color mark plate visual colorimetry according to the test paper operation instructions.As application number is 99210095.x, the name Chinese patent that is called H11 connection urine test paper etc.

During existing instrument interpretation, generally can be divided into single detecting device continuous sweep formula and the discontinuous point of fixity of single detecting device and read formula and the fixed three kinds of modes of multi-detector.Point of fixity reads the formula instrument in use for some time, thereby because of the gear train of instrument wearing and tearing, aging or in the deviation of test strips production run indicator paper block paste position and be placed on the instrument factors such as deviation of position and cause detecting device to read the position to influence measurement result with every indicator paper block center generation deviation; And the fixed detection of multi-detector tends to occur because the inconsistency of detecting device produces new error, simultaneously can not get rid of the deviation of indicator paper block paste position in the test strips production run and be placed on the error that the deviation of position causes on the instrument, and be abandoned by most producers because the cost of the fixed detecting device of multi-detector is too high.Therefore, use single detecting device scan-type detector to have characteristics such as cost detection error lower, that cause because of machinery is few, but because the spacing between each indicator paper block is little on the substrate, when instrument carries out scan-type mensuration, sometimes be difficult to each indicator paper block and substrate are made a distinction clearly, and when carrying out visual colorimetry when judging, because the spacing on the substrate between each indicator paper block is little, the result that indicator paper block may must make mistake with standard color block mispairing on the color board with the color board contrast colors time.

Simultaneously in the production run of test strips, no matter be with automatic production equipment or when adopting hand paste, fixing rectangular indicator paper block on the big substrate of opening, because of position indication or the auxiliary track and localization mark of optics that does not have test paper to paste, often cause paste position inaccurate, product percent of pass, production efficiency and product quality are reduced, the error when detecting is increased.

(3) summary of the invention:

The purpose of this utility model provides a kind of new test strips, is the location and the identification band of instrument location identification usefulness when being convenient to test when being provided with auxiliary paper slip on the zone between each indicator paper block making on substrate.

The purpose of this utility model is to realize like this, this urine test paper bar, comprise substrate and be fixed in on-chip two above indicator paper blocks, different is: the location or the identification band of location identification indicator paper block to be measured when being convenient to instrument test when the zone on the substrate between each test paper is provided with and is convenient to strip and makes.

The front end of first indicator paper block on the described substrate; Or the rear end of last piece indicator paper block; Or not only first indicator paper block front end but also in the end an indicator paper block rear end be provided with an identification band as detecting initial or stopping the sign band.

Described identification tape surface is black or gray layer.

Described indicator paper block is pasted on the substrate by pressure sensitive adhesive double coated, and the one side that itself and indicator paper block are pasted is white layer or reflector layer.

Described substrate is a white, or transparent, or translucent substrate.

Because printing in advance or spraying or attached black or grey bar identification tape on the big substrate of opening, then in the production run of test strips, no matter be with automatic production equipment or when adopting hand paste, fixing rectangular indicator paper block on the big substrate of opening, owing to black or coloured identification bar are arranged often as indication of test paper paste position or automatic equipment optics track and localization auxiliary positioning sign, the position of indicator paper block can be more accurate when then pasting, and can obviously improve product percent of pass, production efficiency and product quality.Secondly, print or be pasted with the black or the grey bar identification tape of identification usefulness in instrument location when being convenient to test on the zone in the use of test strips between each indicator paper block, instrument is easy to (passing through software) when carrying out the mensuration of scan-type each indicator paper block and substrate is clearly made a distinction, reach purposes such as simple to operate, low-cost, precision height.

When carrying out visual colorimetry when judging owing to print on the zone between each indicator paper block or be pasted with black or grey identification band, then with color board contrast colorimetric the time indicator paper block can avoid with color board on the standard color block mispairing and the result that must make mistake.

Be used for auxiliary test strips manufacturing and the black or the grey identification band of instrument location identification usefulness when being convenient to test by printing on the zone between each indicator paper block of test strips or attaching in a word, can obviously improve product percent of pass, production efficiency and product quality, can realize purposes such as instrument is simple, with low cost, detection degree of accuracy height, judge and also can be easy to differentiate when carrying out visual colorimetry, avoid with color board on the standard color block mispairing and the result that must make mistake.
