Description

Technical Field

[0001] This utility model relates to the field of urine culture test strip technology, and in particular to a composite structure of a contamination-resistant urine culture test strip. Background Technology

[0002] In the fields of clinical diagnosis and microbiological testing, urine culture is an important method for detecting urinary tract infections. Traditional urine culture methods typically require sending samples to a laboratory, inoculating them onto solid or liquid culture media, and then determining the pathogen and its drug susceptibility characteristics through colony counting and biochemical identification. However, this method is cumbersome, time-consuming, and susceptible to environmental contamination, potentially leading to false positives or false negatives and affecting diagnostic accuracy. In recent years, urine test strips have been widely used in routine urine testing due to their speed and convenience. For example, they can indirectly infer infection status by detecting indicators such as leukocyte esterase and nitrite using chemical reagents on the test strip. However, these test strips have limited sensitivity and specificity and cannot replace culture methods for pathogen identification and drug susceptibility analysis. Furthermore, traditional test strips are easily contaminated by airborne or operator-borne microorganisms when used in open environments, especially during sample collection, transportation, or testing, which may introduce exogenous bacteria that interfere with the test results. Therefore, we designed a contamination-resistant urine culture test strip composite structure. Utility Model Content

[0024] Working principle:

[0025] By setting the main body 2 of the bacterial culture test strip to be directly installed inside the sterile box 1, when urine needs to be dripped into the test strip, the sliding adjustment plate 6 slides on the sliding limit rail 4, thereby opening the sealing top plate 7 to expose the urine adding groove 3. The urine adding groove 3 is used to drip urine into the test strip. Then, the sliding adjustment plate 6 slides on the sliding limit rail 4, and the sealing top plate 7 directly seals and covers the urine adding groove 3. At this time, the positions of the sealing fixing groove 8 and the sealing buckle connector 10 correspond one-to-one. The buckle pin between the sealing fixing groove 8 and the sealing buckle connector 10 is used to fix them, ensuring the sealing stability of the sealing top plate 7 for the urine adding groove 3. The friction pad 11 increases the friction of the sliding adjustment plate 6 when sliding.
