Technical Field

The utility model belongs to the technical field of medical instruments, and particularly relates to a three-column placed urine automatic sectional sampler.

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. At present, urine sampling cups used by medical inspection departments are all open, so that the urine sampling cups cannot be completely closed, and the 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; because the current urine sampling cups used in clinic are all of open single-cavity straight cup type, the taken urine cannot be separated into a front section, a middle section and a rear section, so that errors in a certain range are inevitably caused to the test result, and the correct diagnosis of a doctor is influenced; the urine sampling cup that uses clinically at present need have accompanying personnel to assist when taking a sample, just can conveniently take a sample, send a sample. Because the urine sampling cup can not be placed in a balanced manner, especially when the urine sampling cup is used by a woman, the woman needs to take the sampling cup with one hand, and the other hand can not be used for redundant operation.

In order to solve the defects of the prior art, people have long searched for and put forward various solutions. For example, the chinese patent document discloses a novel urine sampler [202020215554.4] for facilitating urine transfer, which comprises a urine sampling cup, a urine outlet pipe is arranged at the bottom of the urine sampling cup, the urine outlet pipe is detachably connected to a test tube; insert valve device that is provided with between urine sampling cup and the urine drain pipe, insert valve device and urine sampling cup and urine drain pipe integral type are connected.

Above-mentioned scheme has solved the problem that easily takes place to overflow when urine is gathered to a certain extent, but this scheme still has a great deal of not enough, for example collection system inconvenient balanced placing, the operation scheduling problem comparatively.
