Vaginal dilation sampler

Abstract

The invention provides a vaginal dilatation sampler, comprising an upper duck bill piece, a lower duck bill piece, a grip handle vertically connected with the upper duck bill piece and an operation handle vertically connected with the lower duck bill piece. A plurality of smooth slots are arranged on the arcuate shell wall of the front section of the upper duck bill piece, and the arcuate groove at the top end of the lower duck bill piece is embedded with an upper seal piece to form a half-open container cavity. The upper part of that grip handle is a through observation window, and a lower part is a strip-shaped open groove provided with a positioning structure. A lateral edge for preventing sliding is arrange on that outer side of the operation handle, and the bottom of the lateral edgeis a triangular prismatic protrusion, and a positioning block is arranged on the inner side correspond to the triangular prismatic protrusion and matched with the positioning structure of the lower part of the grip handle, so that the grip handle and the operation handle are slidably combined together. The vaginal dilatation sampler ensures the function of the vaginal dilator itself, the vaginal secretion specimen can be completely and standardized and collect at multiple points, the specimen can be kept as original as possible and sent for examination, and the examination result is more in conformity with the original actual situation of the vaginal microenvironment. The vaginal dilatation sampler ensures the biosafety of the patients and the environment.

Description

technical field [0001] The invention belongs to the technical field of gynecological medical equipment, and in particular relates to a vaginal dilation sampler. Background technique [0002] Vaginal dilator is a kind of disposable sterile operating device commonly used in gynecology departments of various hospitals. [0003] At present, in order to complete the gynecological examination, the gynecologist needs to use a sterile swab (such as a cotton swab) to scrape the vaginal secretions (leucorrhea, hereinafter referred to as vaginal discharge) in the expanded vaginal posterior fornix or vaginal side wall while observing the vaginal pathology. Vaginal secretions), and then put the obtained vaginal secretions in a specific test tube or smear it on a glass slide and send it to the laboratory for examination. [0004] The above-mentioned sampling process has the following disadvantages: 1. Use a sterile swab (such as a cotton swab) to sample a single position on the vaginal s...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned sampling process has the following drawbacks: 1. Use a sterile swab (such as a cotton swab) to take samples from the side wall of the vagina or the posterior fornix of the vagina at a single location, and the samples taken are not representative of the vaginal microenvironment; 2. Due to dry cotton swabs, etc. The interference of sterile swabs, test tubes or additives such as physiological saline in test tubes, etc., and the long delivery process will affect the original properties of vaginal secretion specimens, resulting in changes in the pH value of vaginal secretions, hydrogen peroxide, white blood cells, etc. The detection accuracy of lipase, sialic anhydrase, β-glucuronidase and other indicators; 3. The adsorption of the swabs such as sterile cotton swabs to the detection objects (such as various microorganisms) caused inaccurate detection; 4. Caused collection Waste of sterile swabs of specimens, test tubes and liquids in test tubes; 5. Waste of time for doctors to collect specimens and time for patients to see a doctor

[0005] In many years of clinical testing work, it was found that after the inspection of gynecological vaginal secretions, especially the relevant indicators and standards for the detection of microecology of the female reproductive tract proposed by modern gynecology, in the actual inspection process, the consistency between the inspection results and clinical symptoms is very poor
