A vaginal secretion sampling device used in clinical obstetrics and gynecology

Abstract

The invention discloses a clinical vaginal secretion sampling device for obstetrics and gynecology, comprising a fixed block with activity slots positioned on one side of the fixed block; the link blocks are installed at the sliding activity slot, and the attachment blocks are connected with the link block on one side near the opening of the activity slot; a sampling tank is arranged at the activity slot, a liquid absorption head is fixed at the side of the sampling tank away from the link block, the open holes are fixed at the side of the sampling tank near the liquid absorption head; the open holes are communicated to the liquid absorption head, a piston is installed at the sliding sampling tank, a push rod motor is fixed at the side of the sampling tank away from the liquid absorption head, and the output shaft of the push rod motor extends to the sampling tank and connected to the piston. The clinical vaginal secretion sampling device holds a simple structure and is convenient to use to quickly take vaginal secretion, reducing the possibility of vaginal secretion contacting with air, preventing the inaccuracy of test caused by contaminated secretion, improving the accuracy of test and easy operation.

Description

technical field [0001] The invention relates to the technical field of sampling devices, in particular to a vaginal secretion sampling device used in obstetrics and gynecology clinics. Background technique [0002] When performing gynecological examinations in obstetrics and gynecology clinics, it is usually necessary to sample the secretions from the female vagina or cervix, and then send them to the laboratory for testing, so as to make early diagnosis, prevention and early treatment of some gynecological diseases. [0003] Patent application number 201620630183.X, a new patent for a vaginal secretion sampling device for obstetrics clinics, discloses a vaginal secretions sampling device for obstetrics clinics, including sampling bottles, catheters, sleeves, and torsion spring clips. There is a handle at the rear end of the catheter, a push rod inside the catheter, an arc-shaped push plate at the front end of the push rod, a push handle at the rear end of the push rod, and ...

[0003] Patent application number 201620630183.X, a new patent for a vaginal secretion sampling device for obstetrics clinics, discloses a vaginal secretions sampling device for obstetrics clinics, including sampling bottles, catheters, sleeves, and torsion spring clips. There is a handle at the rear end of the catheter, a push rod inside the catheter, an arc-shaped push plate at the front end of the push rod, a push handle at the rear end of the push rod, and a compression spring on the push rod between the push handle and the end of the catheter. , the catheter is covered with a sleeve, and the catheter between the end of the sleeve and the handle is covered with a compression spring. There are two torsion spring clips at the front end of the catheter. , a sampling bottle is fixed between the two clips, and the sampling bottle is composed of an elastic bag, a bottle body, a liquid suction head, and a bottle cap. The cotton swab is absorbent, and the secretion attached to the cotton swab is not easy to release, which brings some troubles to the medical staff of the test. In addition, during the process of taking out the cotton swab, it is easy to touch the vagina or other objects, resulting in The secretion is wiped off, or the cervical secretion is mixed with the vaginal secretion and mixed with other foreign objects, resulting in inaccurate sampling and increasing the difficulty of the work of medical staff. With the advancement of science and technology and the development of society, people have proposed Therefore, we propose a vaginal secretion sampling device for obstetrics and gynecology to solve the above problems
