Description

Ophthalmic swab sampler
Technical Field
The utility model belongs to the technical field of medical instrument, concretely relates to ophthalmology swab sample thief.
Background
The sampling swabs are usually dry swabs, and after sampling, the sampling swabs with sampling specimens are usually put into a protective agent (or preservative) for preservation; because various formulas of the protective agent are different, most of the protective agent is chemical agent, and the protective agent has some corrosiveness, the scheme that a dry wiper is directly soaked in the protective agent firstly, and then a wetted wiper head is taken for sampling a human body is impossible.
In order to solve the problems, the existing sampler divides a sampling pipe into at least two independent chambers, wherein one chamber contains a protective agent, the other chamber contains a swab, the swab can be taken out for sampling only by opening a container when the sampler is used, and then the swab after sampling is put into the protective agent in the other chamber; the other sampler is characterized in that a sealing pipe sleeve is arranged outside the swab, the swab is fixedly connected with a container cover and then directly placed in a container containing a protective agent, and when the sampler is used, the cover is opened to take out the swab, and then the sealing pipe sleeve is removed to carry out sampling.
However, the two conventional samplers at least have the following disadvantages:
1) Taking the first sampler and the second sampler as an example, because two independent chambers usually share one sealing cover, a swab needs to be taken, and the cover needs to be opened, so that the chamber containing the protective agent is exposed outside, and the protective agent is more likely to be contaminated due to long exposure along with different sampling conditions, such as collection of an eye infection sample (especially for collection and detection of the eye infection sample, any small contamination may greatly affect the accuracy of a detection result);
2) Taking the first sampler as an example, since at least two independent chambers are arranged in one sampling tube, and when the cover is covered, in order to prevent the protective agent from leaking into another chamber to pollute the unused swab, the simple cover with sealing performance cannot meet the requirement, the internal structure of the cover needs to be correspondingly improved, which not only causes great manufacturing difficulty and high cost, but also needs to perform corresponding alignment operation when the cover is covered, which causes troublesome operation and affects sampling efficiency;
3) Taking the first sampler as an example, since the swab is directly placed in a chamber, and in order to prevent the swab from being squeezed or damaging the internal structure of the cover, the length of the swab is inevitably smaller than the length of the corresponding chamber, and the aperture of the sampling tube is relatively narrow, it is difficult for an operator to take out the swab during use, the possibility of accidental breakage of the sampling tube (herein, the sampling tube made of glass) is increased, and the protection agent is easily contaminated by repeated swab taking operations;
4) Taking the first and second samplers as an example, when sampling is completed (after the cover is covered again), subsequent detection is performed, and particularly, when the same sample needs to be detected for multiple times, the cover needs to be opened and covered again repeatedly to pour out the protective agent containing the sample and prevent the protective agent from being polluted, so that repeated operation is time-consuming on one hand, and the protective agent is easily polluted due to misoperation;
5) Taking the first sampler as an example, when the sampling is completed (after the cover is closed again), the swabs with the sample are usually placed together in the chamber containing the protective agent, and when the protective agent containing the sample is poured out for detection, the swabs in the chamber in a free and unfixed state will affect the pouring out of the protective agent, especially when the dosage of the protective agent is small after multiple times of sampling.
