Passive type body liquid sample screening and examining device based on paper diaper and using method thereof

Abstract

The invention discloses a passive type body liquid sample screening and examining device based on paper diaper and a using method thereof, relates to an examining device of body liquid sample, and aims to solve the problem that the conventional device is inconvenient to use, a sample with a small volume cannot be measured accurately and reliably, and the results cannot be maintained for a long time. From the top to bottom, the device sequentially comprises a surface layer made of a hydrophilic material, a collecting layer made of a hydrophobic material, a test layer made of a hydrophilic material, a protective layer made of a hydrophobic material, and a read layer made of a hydrophobic material; the collecting layer comprises a central outlet arranged on the center of the collecting layer, and a self locking switch arranged on the center outlet; and the test layer comprises a test layer body, a route network for passing fluids, and a detection reaction reagent block arranged in the route network. The provided device can detect small volume samples, is capable of detecting multiple markers, and has the advantages of reliable test results, long retaining time of results, and user-friendliness.

Description

technical field [0001] The present invention relates to a device for qualitative screening and inspection of small body fluid samples, specifically, a screening and inspection device for sampling bodily fluids in diapers, and also relates to a method for using the device. Background technique [0002] Diapers are frequently used in elderly patients and are known to act as a urine collection tool on their own. For older patients, collecting enough urine samples for urine testing is often a painful and time-consuming process. [0003] The detection of markers and health parameters in human body fluids usually uses paper test strips to provide a qualitative test result. For body fluid analysis, there are many commercial test strips on the market, such as those produced by Bayer in Germany or Roche in Switzerland. Although these commercial test strips are widely used especially in the field of urinalysis, their application in diapers is not feasible, and it is still necessary ...

AI Technical Summary

Problems solved by technology

This patent is to ensure that only the first batch of urine samples are tested by inhibiting the chemical reaction of esterase. However, it is impossible to accurately grasp the amount of the reagent, which may easily lead to inaccurate test results.
