Abstract

The utility model provides a kind of compound microbial sampler, including top cover, sampling pipe and sealing cover, the top cover and the sampling pipe are by fastening composition tubular container, the sealing cover is set at sampling pipe nozzle, equipped with transhipment culture medium in the sampling tube cavity, it samples pipe outer wall and is equipped with time scale axis, the inside of the sealing cover is equipped with sampling rod, cotton swab and the oese of lengthwise, and outer wall is stained with timing node label adhesive paper.The compound microbial sampler, when solving the prior art in the presence of repeatedly inoculation sampling, it needs to extract repeatedly, be inserted into sampling rod, due to the bad placement of the sampling rod of extraction, liquid on sampling rod is easy drippage, so as to cause the problem of environmental pollution and the problem of sample contamination, solves previous sampling inspection process specific aim time misregister simultaneously, can not trace to the source the time the problem of, effectively prevent pollution environment, sample contamination, acquisition it is convenient, easy to detect, record accurate, compact-sized advantageous effects.

Description

A kind of compound microbial sampler

Technical field

The utility model relates to a kind of technical field of microbial detection, sample more particularly to a kind of compound microbial Device.

Background technique

Microbe sampling pipe acquires and transports medium as a micro-biological samples, in medical diagnosis, infectious disease control, dashes forward The detection fields such as public health event are sent out using very extensive.Currently, existing pathogenic microorganism sampling work is mainly single tube Formula sampling: sampling pipe mainly includes that sampling swab, Sampling hold liquid and test tube are constituted, and by smearing, anus is wiped, is swallowed the methods of to wipe and be obtained Take sample source；Execute-in-place process includes being sampled using sampling rod, then saves sampling rod into disposable transhipment culture medium It is temporary, after transport in laboratory testing link, transhipment culture medium need to be picked with cotton swab and carries out increasing bacterium (liquid) culture or direct Inoculation selective medium is separately cultured.And generally require during atual detection entry detection (more diseases are examined It is disconnected), transhipment culture medium repeatedly can be picked with cotton swab, be inoculated with different enrichment liquid and selective medium, and sampling rod needs instead Multiple to take out, insertion easily leads to sample contamination；It is inconvenient that there is also storages when sampling rod takes out simultaneously, and the liquid on sampling rod is easy Drippage, the problem of so as to cause environmental pollution.In whole courses of work, previous sampling inspection process can not every part of sample of accurate recording Each link time of product, so that the time can not be precisely recorded, timing node of tracing to the source, to ensure inspection requirement.

Summary of the invention

In view of this, the utility model is intended to overcome above-mentioned defect existing in the prior art, provide a kind of compound micro- Biological sampling device.

In order to achieve the above objectives, the technical solution of the utility model is achieved in that

A kind of compound microbial sampler, including top cover, sampling pipe and sealing cover, the top cover and the sampling pipe are logical It crosses to be fastened and connected and forms tubular container, the sealing cover is set at sampling pipe nozzle, equipped with transhipment training in the sampling tube cavity Base is supported, the sealing cover is plugged with the sampling rod, cotton swab and oese of lengthwise, one end of sampling rod, cotton swab and oese It is fixed on sealing cover, the other end is immersed in transhipment culture medium as microorganism acquisition position.

When in use, first a certain amount of transhipment culture medium filling in sampling pipe can long-term preservation after sterilized for sampler With use, oese and cotton swab can configure as needed, when using sampler, open sampler top cover, take out sampling rod It is sampled, then turns back to sampling rod in sampling pipe, laboratory is transported in 24 hours, then, according to detection demand, lead to It crosses oese and picks the transhipment culture medium inoculated containing sample in selective culture dish, cotton swab is picked the transhipment culture containing sample Base is inoculated with enrichment liquid, after oese, cotton swab complete corresponding inoculation, oese, cotton swab is done sterilization treatment, experiment is completed Afterwards, sampling pipe is done into sterilization treatment.In the overall process of work, is torn corresponding adhesive paper on top cover outer wall, glued according to step It is labelled to below the time scale axis of operating time, for recording the time of sample acquisition, transhipment, inspection, detection, to trace back Source control.

Compared with the existing technology, the beneficial effects of the utility model are as follows:

1, the compound microbial sampler does not need to extract sampling rod, no when passing through oese or cotton swab subsample Can generate extraction sampling rod it is bad place, the liquid drippage on sampling rod leads to environmental pollution, effectively prevent Pollution environment prevents that sample contamination, sampling are convenient, inoculation is convenient, compact-sized advantageous effects.

2, the compound microbial sampler, the cotton swab and oese have several, can deploy quantity as needed, It can satisfy Multi-use sampling, and multiple determination demand can be met simultaneously in a job, it is not necessary that sampling behaviour is repeated Make, sample contamination can be prevented, wherein cotton swab can also replace sampling rod, and the scene of progress smears sampling, separately can singly match sterile cotton Swab, carries out pharynx swabbing sample, and a pipe can meet multiple use.

3, the compound microbial sampler wipes sampling suitable for anus, swallows the preservation of sample after wiping sampling, Bedpan sampling, And transported from sampling location to testing laboratory, with pending further detection and analysis.
