Description

A kind of bacterial transport culture apparatus

Technical field

It the utility model is related to the technical field of medical test, and in particular to a kind of bacterial transport culture apparatus.

Background technology

The collection and detection of usual micro-biological samples be not in the same place same time.From the collection site of sample by micro- life Thing is safely transported to test site, and can ensure the culture medium that microbial physiology characteristic is basically unchanged, and is typically used as transporting Send maintenance during microorganism.At present, the form of the most common transhipment culture medium in market is divided into two kinds, and one kind is with Semi-solid cell culture For base as the preservative agent for keeping bacterial activity, another kind is to be used as the preservative agent for keeping bacterial activity using fluid nutrient medium.It is existing Transhipment culture medium for heiicobacter pylori cultivation sample has the following disadvantages：Swab head is circular cotton swab, helicobacter pylori It is usually mucosa tissue to cultivate sample, very sticky, is not easy to scrape, and is not easy to peel off sample from swab again during inoculation, wipes The sample carrying capacity that subheader can obtain is very low；After sampling, swab head still has part unavoidably after stretching into semisolid culturemedium Area is exposed in air, and helicobacter pylori exposure air can occur spheroidization and can not grow for 30 minutes, and neat liquid turns Fortune culture medium easily causes sample to be exposed in air after then being sampled due to sampling pipe due to tilting or overturning；In operating process The hand contact swab handle of middle operator, will easily produce pollution.The transhipment culture medium for being additionally useful for anaerobic bacteria culture sample is same Swab head be present and stretch into after semisolid culturemedium and have area unavoidably in the air, strict anaerobes is exposed to air In 10 minutes it is i.e. dead and can not grow, changing transhipment medium component using this transhipment culture apparatus can be used to anaerobic bacteria training Support sample transhipment.

Utility model content

In view of the shortcomings of the prior art, the purpose of this utility model aims to provide a kind of bacterial transport culture apparatus, is easy to Use, and the occurrence probability of sample contamination can be reduced.

To achieve the above object, the utility model adopts the following technical scheme that：

A kind of bacterial transport culture apparatus, including pipe, screw lid and sampling swab are transported, it is provided with the transhipment pipe under Semisolid culturemedium and fluid nutrient medium on and；The screw lid is matched with the mouth of pipe of transhipment pipe, and screw lid is detachably connected In on the mouth of pipe of transhipment pipe；The length of the sampling swab is matched with the length of transhipment pipe, and sampling swab includes bar from top to bottom Portion and head, the head are in flat spade-type, are provided with pre- breakpoint in bar portion, sampling swab is prejudged after stretching into semisolid culturemedium The location matches of point are in being provided with the bayonet socket that is matched with pre- breakpoint on the position of screw lid, the inner side on the screw lid top.Transhipment Medium component can be with changes in demand.

As a kind of improvement of the present utility model, artificial cellosilk is embedded with head.

As another improvement of the present utility model, the ratio between thickness of semisolid culturemedium and fluid nutrient medium is 3:1.

As another improvement of the present utility model, the first screw thread is provided with the inner side of screw lid lid body, the transhipment pipe The mouth of pipe on the outside of on be provided with the second screw thread, first screw thread and second screw thread of the screw lid through threaded engagement are removably attachable to Transport on the mouth of pipe of pipe.

As another improvement of the present utility model, the length for transporting pipe is 75~180mm, transports the cross-sectional diameter of pipe For 12~18mm.

As another improvement of the present utility model, fluid nutrient medium is less than with transporting the distance between tube top end end face 3cm。

As another improvement of the present utility model, fluid nutrient medium is not more than with transporting the distance between tube top end end face 2cm。

It is raised that vertical striped is provided with as another improvement of the present utility model, on the outside of screw lid lid body.

The beneficial effects of the utility model are：It is embedding on the outside on swab head using the swab head of flat spade-type Provided with the artificial cellosilk to external radiation, in favor of peeling off sample from swab when sampling and being inoculated with, it is easy to use；Culture Base includes semisolid culturemedium and fluid nutrient medium from bottom to top, after bottom semisolid culturemedium is stretched on the head of swab on Layer fluid nutrient medium can fill automatically stretched into due to swab caused by space, so as to avoid sample and air contact completely, Solve the problems, such as in pure semisolid culturemedium that swab is stretched into after culture medium to form space and cause sample part and air contact；Wipe Pre- breakpoint is provided with the bar portion of son, swab head is stretched into after semisolid culturemedium and the bar portion of swab fractures at pre- breakpoint, Swab tip is formed after fractureing at pre- breakpoint, the swab tip is arranged on the inner side of screw lid through bayonet socket, then needed swab When head is taken out from semisolid culturemedium, swab can be taken out with screw lid, avoided by the way that screw lid is screwed out into transhipment pipe The hand of operating personnel contacts swab handle and sample contamination occurs；Fluid nutrient medium and the distance between transhipment tube top end end face are little In 2cm, so as to ensure volume accounting of the culture medium in pipe is transported, avoid making sample sudden and violent because transhipment pipe tilts or reverse Dew；It is exactly alike to transport pipe shaft size and the in general sampling test tube of pipe, then it is equally applicable suitable for the rack for test tube of sampling test tube Managed in transhipment, be easy to deposit and transport transhipment pipe.
