The invention discloses a detection reagent strip for detecting microalbumin in urine. The detection reagent strip comprises a substrate and a filter paper piece, wherein the filter paper piece is attached on the substrate; the filter paper piece is sequentially immersed into an A solution and a B solution; the A solution is a buffered aqueous solution comprising sodium citrate, citric acid and concentrated hydrochloric acid; and the B solution is a methyl alcohol or ethanol solution comprising tetrahydrofuran, polypropylene glycol and sulfonephthalein dye. By utilizing the detection reagent strip prepared by the scheme, the sulfonephthalein dye can be quickly reacted with the microalbumin in the urine under acidic conditions, when the concentration of the microalbumin is in a range of 0-200mg / L, test paper presents obvious levels from colorlessness to mazarine, the levels are easy to visually distinguish and machine-readable, the measurement result is accurate and not disturbed by other ions in the urine, and the performance is stable. Meanwhile, a preparation method of the reagent strip is simple, convenient and rapid, the manufacturing cost is low, and the preparation method is suitable for large-scale popularization and application.

The present invention relates to a urine guiding device when people piss in stand or seat poses, especially relates to a piss guider which is characterized in that: the guider is trough shape, one end is urine receiving place, and the guider has a guiding place. The height of the urine receiving end port bottom of the guider is higher than the bottom of the guider, the urine receiving port is inclining shape. The guider has water absorb layers, a holding and hanging member, folding lines, connection members on two sides connected temporarily or fixed connected, and a urine testing strip. A lining is disposed in the guider. Water absorb layers are on the lining of the guider and at the urine receiving place. The guiding place is connected with a conduit and a urine reception device. The piss guider is convenient in use, can be used by male and female, saves material and reduces work procedure. The person using the piss guider not only can piss in stand pose, but also can piss seat on the bed, bench or wheelchair.

The timing of the reaction of moisture-sensitive reagents for detecting the presence of analytes, e.g. leukocytes in urine samples, is used to detect when the reagents have been compromised by excess humidity. The ratio of light reflectance at wavelengths characteristic of the products of reaction between the reagents and the analyte and an infra-red reference dye is measured at two preset times after a urine sample has been applied to a test strip and used to determine whether the reagents have been compromised by excessive humidity. The presence of unusually dark samples is determined from the reflected light at 470 and 625 nm in order to confirm that the test strips are humidity-compromised.

The invention relates to an automatic urine collecting unit, and relates to the technical field of urine analysis. The automatic urine collecting unit comprises a toilet stool including a cover and abody, and the body is provided with a concave urine collecting tank, a spreader plate, a sampling unit with a metering function, a urine test strip, a sample tank, a conveyor belt and a recovery tank.The sample tank is provided with a spreader plate, and the urine collecting tank is communicated to the sample tank through the sampling unit. The sampling unit adds the urine into the sample tank after the urine is metered, and the urine wets the urine test strip after flowing through the spreader plate. One end of the conveyor belt is connected with a urine analysis module for conveying the urine test strip to the urine analysis module when the conveyor belt rotates forward. The automatic urine collecting unit is simple in structure, capable of identifying users automatically and accurately, conducting quantitative urine collection and analysis specific to the users and conducting archiving for the users and sanitary in use.

An embodiment of the present invention provides a method and a device for determining the detection result of urine test paper, wherein the method includes: determining the target color value of the urine test paper image detection area; calculating the target color value corresponding to the color value of different preset standard colors The first color difference value; calculate the second color difference value corresponding to the target color value and the color value of different preset standard colors; for the calculated multiple first color difference values ​​and multiple second color difference values, it will be compared with the same preset color difference value Set the weighted sum of the first color difference value and the second color difference value corresponding to the color value of the standard color to obtain multiple comprehensive color difference values; The concentration represented by the preset standard color is determined as the detection result. The method and device for determining the detection result of the urine test paper according to the embodiments of the present invention can improve the accuracy of determining the detection result of the urine test paper.
