A metabolite sampling device

Technical field

The utility model relates to the technical field of metabolite collection, specifically a metabolite sampling device.

Background technique

Vaginal secretions are liquids secreted by the female reproductive system. During gynecological examinations, vaginal secretions are often detected to determine infections or tumors in the female reproductive system.

Chapter 15 of the fourth edition of the "National Clinical Laboratory Procedures" points out that when collecting vaginal secretion specimens, cotton swabs soaked in physiological saline are generally used to collect materials from the deep vagina or the posterior vaginal fornix, cervical opening, etc. After obtaining the specimen, It should be sent for analysis immediately. When analyzing vaginal secretion samples, use the normal saline smear method to observe the collected vaginal secretions, or use the normal saline hanging drop method to evenly smear, and observe its cleanliness and presence of special cells under the microscope. It can be seen from the above operating procedures that when sampling and analyzing vaginal secretions, cotton swabs soaked in physiological saline need to be used.

Patent application number CN205157221U discloses a disposable secretion sampler, which includes a liquid-holding tube with a connecting fixture at the open end. A breaking rod is fixed at one end of the connecting fixture close to the liquid-holding tube. The other end of the connecting fixture is connected to the One end of the sampling rod is fixed, and the other end of the sampling rod is provided with a fiber head.

The sampling swabs used in the above-mentioned vaginal secretion sampling devices are mostly dry sampling swabs placed in sealed tubes. Patients use dry sampling swabs to take samples by themselves and then seal and submit them to the laboratory for testing. Dry sampling swabs not only cause the user to Uncomfortable feeling, and multiple swabbing and sampling are required to reach the test specimen volume, which can easily cause damage to the vaginal wall. At the same time, according to clinical reflections, cotton wool has an inhibitory effect on microbial activity, affecting the accuracy of diagnostic results. In some special cases, obtaining Vaginal secretion samples cannot be tested immediately, and the samples need to be placed in culture media for culture;
