Background

When a clinical examination department performs urine examination and sampling, the middle-section urine of the urine of a patient needs to be taken, so that the urine can be more accurate and objective, and the examination result is used for the diagnosis of a clinician. At present, urine sampling cups used in clinical urine tests in medical departments are all of an open single-cavity type and are shared by men and women. Due to the design defect of the sampling cup, the taken urine cannot be separated into the front section, the middle section and the rear section, so that the test result has a certain range of errors, and the accurate diagnosis of a doctor can be directly influenced, thereby causing misdiagnosis. It is also inconvenient to use for design reasons. Urine sampling cups used by medical inspection departments are all open, so that the urine sampling cups cannot be completely closed, and hands of operators are polluted during sampling; because the used urine sampling cup is only suitable for men, the women can increase certain difficulty in sampling due to physiological reasons, and the hands are more easily polluted.

In order to solve the defects of the prior art, people have long searched for and put forward various solutions.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in figures 1-4, the three-cavity automatic mid-section urine sampling device comprises a urine collector body 1 with a urine collecting cavity 11 inside, a urine inlet 12 communicated with the urine collecting cavity 11 is arranged above the urine collector body 1, a fore-section urine outflow leakage pipe 13 communicated with the urine collecting cavity 11 is vertically arranged below the urine collector body 1, the middle section urine flows out the small opening 14 and the unnecessary urine discharge pipe 15, urine collection cavity 11 bottom is provided with the collection urine tube 16 that encloses the anterior section urine and flows out the small opening 13 upper end and keep off, it is relative with collection urine tube 16 to advance urine mouth 12, be provided with current limiting mechanism 2 between anterior section urine outflow small opening 13 and the collection urine tube 16, be provided with the overflow baffle 17 that encloses and keep off in middle section urine outflow small opening 14 upper end both sides between urine collection cavity 11 inboard and the collection urine tube 16 outside, the overflow breach 19 relative with the overflow chamber 18 that is located between the overflow baffle 17 is opened to collection urine tube 16 side. When collecting urine, urine flows into the urine collection cylinder 16 at the upper end of the front section urine outflow leakage pipe 13 from the urine inlet 12, middle section urine flows into the overflow cavity 18 at the upper end of the middle section urine outflow leakage pipe 14 from the overflow notch 19 at one side of the urine collection cylinder 16 along with the discharge of urine, the middle section urine flows out of the leakage pipe 14 and then collects middle section urine required by urine detection, and redundant urine flows into the redundant urine discharge pipe 15 from the upper end of the overflow baffle 17.

By limiting the length of the tube body, the capacity of each tube body is limited, the front section urine outflow leakage tube 13 and the redundant urine discharge tube 15 are long, the discharged urine is not adopted, and the middle section urine outflow leakage tube 14 collects middle section urine with uniform quality.

Preferably, a cylindrical limiting block 7 is fixed on the outer side of the midstream urine outflow leakage pipe 14. The limiting block 7 is tightly pressed with the external pipeline, so that the sealing performance of the joint of the body of the middle-section urine outflow leak pipe 14 is improved.
