Description

Urine sample collection and processing device for nucleic acid testing

Technical Field

The utility model relates to the technical field of sample collection and processing, and in particular to a urine sample collection and processing device for nucleic acid detection.

Background Art

Nucleic acid testing generally refers to nucleic acid testing methods, which are mainly used to detect the presence of viruses in the body. The substance detected by the nucleic acid testing method is generally the nucleic acid of the virus. The nucleic acid of the invading virus is detected in the respiratory specimens, blood specimens or fecal specimens of the subject to determine whether the virus is infected. If the test result is negative, it mostly indicates that the virus is not infected; if the test result is positive, the virus may have been infected or false positive symptoms have occurred, and relevant tests are generally required again.

Urine testing is a commonly used detection method in clinical practice. When conducting urine testing, urine samples need to be collected. In daily testing, midstream urine is usually collected for testing. However, in the common way of collecting urine, urine is usually collected through a disposable collection box and then the urine in the collection box is introduced into a test tube for storage.

DETAILED DESCRIPTION

The technical solution of the utility model is further specifically described below through embodiments and in conjunction with the accompanying drawings.

Embodiment: As shown in Figures 1-4, a urine sample collection and processing device for nucleic acid detection includes a urine collection tube 1, and a scale value 4 is provided on the outer circular wall of the urine collection tube 1. A lower through pipe 5 is provided at the lower end of the urine collection tube 1, which is connected to the urine collection tube 1 in an integrated manner, and an aluminum film 6 is provided at the lower end of the lower through pipe 5, which is bonded to the lower through pipe 5. An external thread groove 3 is provided at the upper part of the urine collection tube 1, and a tube cover 12 is provided at the upper end of the urine collection tube 1, which is sleeved and fixed to the external thread groove 3. A push rod member 2 is provided in the urine collection tube 1, which is movably nested with the urine collection tube 1. The push rod member 2 includes a connecting rod 10, and a rubber piston 11 is provided at the lower end of the connecting rod 10, which is movably nested with the urine collection tube 1. A pressure plate 9 is provided at the upper end of the connecting rod 10, which is integrated with the connecting rod 10 and has a diameter larger than that of the urine collection tube 1.
