Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an auxiliary device for sampling fluid accumulation and a method for using the same. Background technique [0002] Endocrinology is a kind of internal medicine. It mainly conducts more detailed tests on people's endocrine problems, and the results of the tests can be more clearly reflected, enabling doctors to prescribe the right medicine and regulate endocrine. The way to supplement estrogen, but it is worth noting that if you supplement estrogen by mistake, it may increase the risk of endometrial cancer or breast cancer. Therefore, before supplementing estrogen, you must go to the hospital for an examination of the actual estrogen level, and use the correct method and dosage under the guidance of a doctor. Another good way to treat endocrine disorders is traditional Chinese medicine therapy. According to the different conditions of different endocrine patients, through...
