Problems solved by technology

The traditional endocrinology department usually uses a syringe to extract the effusion. When using it, the needle of the syringe is pierced into the patient's effusion, and the syringe is used to extract the effusion from the patient's lesion. However, during the puncture process, part of the needle The blood clot in the needle enters the needle, so that when the syringe extracts the effusion, the blood clot in the needle enters the syringe preferentially, causing the subsequent effusion and blood to enter the syringe to be mixed together, resulting in the need for subsequent analysis of the effusion and blood clot The separation between, the efficiency of influence test

Abstract

The invention discloses a sampling extracting device used based on internal secretion effusion. The sampling extracting device comprises a needle cylinder, wherein a first liquid-connecting cavity isformed in the needle cylinder, a connecting pipe is arranged at one end of the needle cylinder, is located in the first liquid-connecting cavity and is sleeved with an elastic arc-shaped plate, and sliding blocks are arranged at two ends of the arc-shaped plate; a limiting slot is formed in the inner wall of the end part of the needle cylinder; when the arc-shaped plate moves towards the end partof the needle cylinder, the two sliding blocks can move towards two sides of the needle cylinder; first moving rods are arranged on the side walls of the sliding blocks and are glidingly connected with the sliding blocks; first cavities are formed in two sides of the inner wall of the needle cylinder, first moving plates and the second moving rods are arranged in the first cavities, and the secondmoving rods penetrate into the first liquid-connecting cavity; a sampling rod is further arranged in the needle cylinder, a second liquid-connecting cavity is formed in the sampling rod, a second piston and a second piston rod are arranged in the second liquid-connecting cavity, limiting blocks are arranged on two sides of the outer wall of the sampling rod, and limiting blind holes are formed inthe side walls of the limiting blocks; and an unlocking assembly is further arranged in the end part of the needle cylinder.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a sampling and extraction device based on the application of endocrine effusion. 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 cup...
