Sampling cotton swab device

Abstract

Relating to the technical field of medical instruments, the invention discloses a sampling cotton swab device, which comprises a cotton swab box, the inner walls of the upper side and the lower side of the cotton swab box are fixedly connected with the upper end and the lower end of a rotating shaft through bearings, a fixing sleeve is fixedly connected to the rotating shaft, and the outer sides of the upper end and the lower end of the rotating shaft are sleeved with torsional springs. Through mutual cooperation of the rotating shaft, the fixing sleeve, the torsional springs, a clamping arc plate, a baffle, a push rod, a spring and a T-shaped sliding block, after cotton swabs are placed into the cotton swab box, the torsional springs drive the fixedly connected fixing sleeve to rotate anticlockwise, and the fixing sleeve drives the clamping arc plate to rotate anticlockwise through a fixedly connected connecting plate; the cotton swabs placed in the cotton swab box are driven to be inlap joint with the baffle all the time along the inner side wall of the cotton swab box, then the push rod is pressed downwards to bring the lap joint arc plate to be in lap joint with the upper endsof the cotton swabs to push the cotton swabs to move out of the cotton swab box for sampling, and the situation that one cotton swab needs to be taken again for use after sampling is avoided. The sampling efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a sampling cotton swab device. Background technique [0002] Sampling is to select a representative sample from the target object. The popular explanation is to take a small number of samples from a large number of items or materials. At present, when samples are collected for testing in the medical field, in order to avoid deviations in the test results, cotton swabs are often used. Sampling with a disposable sanitary product will improve the accuracy of the test results. [0003] Most of the existing sampling methods are that the staff hold a cotton swab with their hands and dip a little in the sample to be collected for testing. However, the cotton swab is mostly short, and the hands of the medical staff often stick to the sample, which is very inconvenient to clean up later. When using the cotton swab placement device for auxiliary sampling, often only a single cotto...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a sampling cotton swab device, which solves the problem that the hands of medical staff often stick to the sample, and it is very inconvenient to clean up later, and when using the cotton swab placement device for auxiliary sampling, it is often only possible to hold Place a single cotton swab, and after the sampling is completed, a new cotton swab needs to be fixed again to continue to use, which reduces the problem of sampling efficiency
