Description

Technical Field

[0001] This invention belongs to the field of urine detection technology, specifically relating to a colloidal gold test strip for detecting bath salts in urine samples. Background Technology

[0002] A urine sample is a urine sample collected during a urine test. Urine samples have various uses in medical examinations, primarily for assessing the health of the kidneys and urinary system. Types of urine samples include morning urine, urine collected at any time, postprandial urine, timed urine, and urine for culture.

[0003] A Chinese utility model patent (Publication No.: CN106324264A) discloses an ovulation test strip and its processing technology, comprising a sample pad, a colloidal gold conjugate pad, an NC nitrocellulose membrane, an absorbent plate, and a PVC plate. The sample pad and its lower colloidal gold conjugate pad, the colloidal gold conjugate pad and its lower NC nitrocellulose membrane, and the NC nitrocellulose membrane and its upper absorbent plate are partially overlapped, with overlap widths of 1-4 mm respectively. The colloidal gold conjugate pad is sprayed with colloidal gold-labeled JHKLH-α antibody. Two parallel antibody capture lines are drawn on the NC nitrocellulose membrane; one line, closer to the colloidal gold conjugate pad, contains JHKLH-β antibody and serves as the detection line; the other line contains a determined concentration of goat anti-mouse IgG antibody and serves as a standard concentration colorimetric control line. This invention solves the problem of false positives in ovulation test strips detecting samples containing HCG.

[0004] However, in implementing the relevant technology, the above-mentioned ovulation test strip and its processing technology have the following problems: In the use of the existing technology, if too much urine sample is added, the excess sample may exceed the membrane's carrying capacity, causing some liquid to not completely pass through the reaction zone, resulting in background interference or signal weakening. The device collects excess urine sample to avoid the excess sample possibly exceeding the membrane's carrying capacity. Therefore, a colloidal gold test strip for detecting bath salts in urine samples is proposed. Utility Model Content

[0005] This invention proposes a colloidal gold test strip for detecting bath salts in urine samples, which solves the problem in related technologies where, if too much urine sample is added, the excess sample may exceed the membrane's carrying capacity, causing some liquid to not completely pass through the reaction zone, resulting in background interference or signal weakening.

[0006] The technical solution of this utility model is as follows: a colloidal gold test strip for detecting bath salts in urine samples, comprising: a PVC board, wherein a collection groove is provided on the top surface of the PVC board, and a first absorbent cotton is fixedly connected inside the collection groove;

[0007] A sample pad is fixedly connected to the top surface of the PVC board, and a colloidal gold bonding pad is fixedly connected to the top surface of the PVC board. The sample pad and the colloidal gold bonding pad are overlapped and connected.

[0008] Preferably, an NC nitrocellulose membrane is fixedly connected to the top surface of the PVC board, and the NC nitrocellulose membrane overlaps and is connected to the colloidal gold bonding pad.

[0009] Preferably, the top surface of the PVC board is provided with a placement block, and a placement groove is provided on one side of the placement block.

[0010] Preferably, a second absorbent cotton is fixedly connected inside the placement groove, and the second absorbent cotton overlaps and is connected to the NC nitrocellulose membrane.

[0011] Preferably, the top surface of the NC nitrocellulose membrane is provided with a detection line, and the top surface of the NC nitrocellulose membrane is provided with a quality control line.

[0012] Preferably, a gold labeling pad protective strip is adhered to the top surface of the sample pad and the colloidal gold binding pad.

[0013] The working principle and beneficial effects of this utility model are as follows:

[0014] By pouring the urine sample to be tested onto the sample pad, if too much urine is poured, the urine inside the sample pad will directly seep into the collection tank, allowing the first absorbent cotton to initially absorb the excess urine. Simultaneously, the urine water inside the sample pad enters the colloidal gold-binding pad, facilitating subsequent urine sample testing. When the urine sample passes through the colloidal gold-binding pad and onto it, it can react on the NC nitrocellulose membrane. Because the second absorbent cotton overlaps and connects with the NC nitrocellulose membrane, it can further absorb excess urine on the NC nitrocellulose membrane, thus preventing excessive sample from exceeding the membrane's capacity and causing some liquid to not completely pass through the reaction zone, resulting in background interference or signal weakening. A placement block is provided on the top surface of the PVC board to prevent the user's hands from coming into contact with the urine. Attached Figure Description

[0021] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0022] Example 1

[0023] Please see Figure 1 - Figure 4 A colloidal gold test strip for detecting bath salts in urine samples, comprising:

[0024] PVC board 1, the top surface of PVC board 1 is provided with a collection groove 2, and a first absorbent cotton 3 is fixedly connected inside the collection groove 2;

[0025] Sample pad 4 is fixedly connected to the top surface of PVC board 1. Colloidal gold bonding pad 5 is fixedly connected to the top surface of PVC board 1. Sample pad 4 and colloidal gold bonding pad 5 are overlapped and connected.

[0026] This invention provides a colloidal gold test strip for urine sample testing in a bath salt. The urine sample to be tested is poured onto a sample pad 4. If too much urine is poured, the urine inside the sample pad 4 will directly seep into the collection tank 2, allowing the first absorbent cotton 3 to initially absorb the excess urine. Simultaneously, the urine water inside the sample pad 4 enters the colloidal gold binding pad 5, facilitating subsequent urine sample testing. This avoids background interference or signal weakening caused by some liquid not completely passing through the reaction zone if too much urine sample is added.

[0027] Furthermore, an NC nitrocellulose membrane 6 is fixedly connected to the top surface of the PVC board 1, and the NC nitrocellulose membrane 6 overlaps and is connected to the colloidal gold bonding pad 5.

[0028] Specifically, by setting up the NC nitrocellulose membrane 6, when a urine sample enters the colloidal gold conjugate pad 5 through the NC nitrocellulose membrane 6, the reaction can take place on the NC nitrocellulose membrane 6.

[0029] Furthermore, the top surface of the PVC board 1 is provided with a placement block 7, and a placement groove 8 is provided on one side of the placement block 7.

[0030] Specifically, by setting up placement block 7, since the top surface of PVC board 1 has placement block 7, the user's hands will not come into contact with urine.

[0031] Furthermore, a second absorbent cotton 9 is fixedly connected inside the placement groove 8, and the second absorbent cotton 9 overlaps and is connected to the NC nitrocellulose membrane 6.

[0032] Specifically, by setting up a second absorbent cotton 9, which overlaps and connects with the NC nitrocellulose membrane 6, the second absorbent cotton 9 can absorb excess urine on the NC nitrocellulose membrane 6 for a second time, thereby avoiding the possibility that excessive sample may exceed the carrying capacity of the NC nitrocellulose membrane 6, causing some liquid to not completely pass through the reaction zone, resulting in background interference or signal weakening.

[0033] Example 2

[0034] Based on Example 1, in this example: the top surface of the NC nitrocellulose membrane 6 is provided with a detection line 10, the top surface of the NC nitrocellulose membrane 6 is provided with a quality control line 11, and the top surfaces of the sample pad 4 and the colloidal gold binding pad 5 are attached with a gold label pad protective strip 12.

[0035] The technical solution provided in this embodiment is as follows: by setting a gold label pad protection strip 12, since the sample pad 4 and the colloidal gold bonding pad 5 are attached with the gold label pad protection strip 12, the gold label pad protection strip 12 can protect the colloidal gold bonding pad 5.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
