CN-224216709-U - Colloidal gold test paper for detecting bath salt by urine sample

Abstract

The utility model relates to the technical field of urine detection and provides a colloidal gold test paper for detecting bath salt of a urine sample, which comprises a PVC plate, wherein the top surface of the PVC plate is provided with a collecting groove, a urine sample to be detected is poured onto a sample pad, if the urine sample is poured more, urine in the sample pad directly permeates into the collecting groove at the moment, so that the first absorbent cotton can primarily absorb the more poured urine, meanwhile, urine water in the sample pad enters the colloidal gold bonding pad, so that the later detection of the urine sample is facilitated, when the urine sample enters the colloidal gold bonding pad through the colloidal gold bonding pad, the reaction can be carried out on an NC nitrocellulose membrane, the second absorbent cotton can secondarily absorb the excessive urine on the NC nitrocellulose membrane, and further, the situation that the excessive sample possibly exceeds the bearing capacity of the NC nitrocellulose membrane, so that part of liquid does not completely pass through a reaction area and background interference or signal weakening is avoided.

Description

Colloidal gold test paper for detecting bath salt by urine sample Technical Field The utility model belongs to the technical field of urine detection, and particularly relates to colloidal gold test paper for detecting bath salt by a urine sample. Background Urine samples refer to urine samples collected during a urine test. Urine samples have a variety of uses in medical examinations, mainly for assessing the health of the kidneys and urinary system. The urine sample species include morning urine, instant urine, post-meal urine, timed urine, and urine for culture. The known Chinese publication authorization utility model (publication No. CN 106324264A) discloses an ovulation test paper and a processing technology thereof, wherein the ovulation test paper comprises a sample pad, a colloidal gold bonding pad, an NC nitrocellulose membrane, a water absorbing plate and a PVC plate, and is characterized in that the sample pad is connected with the colloidal gold bonding pad at the lower part of the sample pad, the colloidal gold bonding pad is connected with the NC nitrocellulose membrane at the lower part of the colloidal gold bonding pad, the NC nitrocellulose membrane is respectively and partially overlapped with the water absorbing plate at the upper part of the colloidal gold bonding pad, the overlapping width is respectively 1-4mm, the colloidal gold bonding pad is sprayed with jhkLH-alpha antibodies marked by the colloidal gold, two parallel antibody capturing lines are respectively marked on the NC nitrocellulose membrane, one jhkLH-beta antibody close to the colloidal gold bonding pad is used as a detection line, and the other one contains goat anti-mouse IgG antibody with determined concentration as a standard concentration color development quality control line. The utility model solves the problem of false positive of the HCG-containing sample detected by the ovulation detection test paper. However, in the related art, the problem of the ovulation test paper and the processing technology thereof is found that in the using process of the prior art, if the excessive sample of urine is excessively added, the excessive sample may exceed the bearing capacity of the membrane, so that part of the liquid does not completely pass through the reaction area, and the background interference or signal attenuation is caused. Disclosure of utility model The utility model provides a colloidal gold test paper for detecting bath salt of a urine sample, which solves the problems of background interference or signal weakening caused by partial liquid not completely passing through a reaction zone because excessive sample possibly exceeds the bearing capacity of a membrane after the urine sample is excessively added in the related art. The colloidal gold test paper for detecting bath salt of urine samples comprises a PVC plate, wherein a collecting tank is arranged on the top surface of the PVC plate, and first absorbent cotton is fixedly connected inside the collecting tank; The sample pad, sample pad fixed connection is in the top surface of PVC board, the top surface fixedly connected with colloidal gold bonding pad of PVC board, sample pad with the overlapping of colloidal gold bonding pad is connected. Preferably, the top surface of the PVC plate is fixedly connected with an NC nitrocellulose membrane, and the NC nitrocellulose membrane is connected with the colloidal gold bonding pad in an overlapping manner.
