Abstract

The utility model discloses a bacteria culture set comprising a body, a base, a filter and a cap. At the top of the body installed the filter and the orifice of the fluid inlet pipe. The body is fixed on the base and between them equips the lower filtration membrane. Between the body and the filter is the upper filtration membrane. The orifice of the fluid inlet pipe is consisted of two concentric pipes and the fluid inlet pipe is fixed at the clearance between the two concentric pipes. The exit of the fluid inlet pipe provides a damp block. The same rubber caps are installed respectively at the riser vent of the filter and the discharge hole under the base. The capacity calibration tails is on the body. The utility model of the bacteria culture set can be widely used in fields of pharmaceutical, doping test, medical appliance for analyzing and detecting. The utility model has a good effect in culturing bacteria, is easy to operate and can decrease the labor intensity of the operators.

Description

Colony culture device

Technical field

The utility model relates to a kind of colony culture device, particularly a kind of colony culture device that can be used to cultivate and detect all kinds of bacterial classifications in the microorganism detection field.

Background technology

Colony culture device is used for the Bacteria Detection of Experiment on Microbiology and medicine, traditional method is earlier sample to be filtered by strainer, millipore filtration is divided into three parts again, in being housed, cultivates by the container of a certain amount of substratum (pipe or bottle) respectively, but this method complicated operation easily causes the exogenous pollution of testing process.

Application number is that 93219087.1 utility model patent discloses a kind of disposable colony culture device, form by plastic casing, base, web plate, filtering membrane, with a threeway three incubators are tied, can evenly filter, suck substratum simultaneously, carry out microbial culture.But this device operation is more loaded down with trivial details, and incubator is air-tight state in the culturing process, and ventilation property is bad, is unfavorable for the microorganism growth breeding.

Application number is 95203829.3 the disclosed technology of utility model patent, be that incubator is linked to each other with peristaltic pump by flexible pipe, an aperture that has air filter is arranged at the top of incubator, can fully prevent outside contamination, but because shell can not be split, can only disposablely use, and be transparent plastics, cause environmental pollution easily with material.

Application number is in 96245812.0 the disclosed colony culture device of utility model patent, and cup and base are that gummed forms, or with being threaded.

All do not relate to the fixing means of filtering membrane and filter cap in the foregoing invention content conveniently use, the reliable connection of flexible pipe etc., these factors all can cause the unstable of various Bacteria Detection of microorganism detection and medicine and the inconvenience of operation etc. in the actual use of colony culture device.

Summary of the invention

The utility model provides a kind of colony culture device that can be used to cultivate and detect all kinds of bacterial classifications in the microorganism detection field.

Colony culture device, comprise cup, cup, strainer, cup cap, the top of cup is equipped with the strainer and the feed liquor mouth of pipe, cup is fixed on the cup, between cup and the cup filtering membrane is installed down, filtering membrane is being installed between cup and the strainer, the feed liquor mouth of pipe is made up of two concentrically ringed pipelines, liquid-inlet pipe is fixed on two gap locations between the concentric(al) circles, and the exit of the feed liquor mouth of pipe is provided with block.

Identical rubber cup cap is housed on the discharge port of the ventilation mouth on strainer top and cup bottom, is carved with the containing mark line on the cup.

The utility model has designed the feed liquor mouth of pipe of concentric double pipe, has prevented that effectively the feed liquor mouth of pipe from causing fracture easily in processes such as processing, transportation, simultaneously in order to prevent that liquid from impacting the situation that fluid surface and filtering membrane impact filtration when entering cup; On the discharge port of the ventilation mouth on strainer top and cup bottom, identical rubber cup cap is housed, makes liquid enter cup glibly and do not guarantee that by atmospheric pollution and when the liquid filtering bacterium is trapped on the filtering membrane; On cup, be carved with the containing mark line, reflect the capacity of the liquid in the cup intuitively.

Colony culture device of the present utility model can be widely used in the analyzing and testing of pharmaceutical industry, medicine inspection industry, medicine equipment industry etc., collection bacterium culture effect is good, easy to operate, can alleviate labor intensity of operating personnel, be to a kind of lifting in essence of existing analysing and detecting method, exploitation to microorganism detection and new drug has substantial help, to alleviating labor intensity of operating personnel, promotes the world power of striving unexpectedly in fields such as pharmaceutical industry, medicine inspection industries and all has very active operation significance.

Description of drawings

Fig. 1 is the structural representation of colony culture device of the present utility model.

Embodiment

As shown in Figure 1, a kind of colony culture device comprises cup 1, cup 2, strainer 3, cup 1 is fixed on the cup 2, on the top 5 of cup 1, strainer 3 is housed, between cup 1 and the strainer 3 filtering membrane 10 is installed, the following filtering membrane 9 that can hold back bacterium is installed between cup 1 and cup 2, have the feed liquor mouth of pipe 8 on the top of cup 1, the feed liquor mouth of pipe 8 is made up of two concentrically

ringed pipelines

11, and 12 places, gap between two concentric(al) circless are liquid-inlet pipe 13 fixedly, and a block 14 is arranged in the exit of the feed liquor mouth of pipe 8.Prevent that so effectively the feed liquor mouth of pipe from causing the situation of fracture easily in processes such as processing, transportation, prevent that also liquid from impacting fluid surface when entering cup and filtering membrane impacts filtration simultaneously.

The cup cap that identical rubber cup cap 4, two places are housed on the ventilation mouth 15 on the strainer 3 and the discharge port 16 of cup bottom 6 can be general.Cup cap 4 on ventilation mouth 15 is opened, and the cup cap 4 on the discharge port 16 covers, and liquid can be stored in the cup 1; Cup cap 4 on the ventilation mouth 15 covers, and the cup cap 4 on the discharge port 16 is opened, and cup 1 internal pressure increases, liquid can be glibly by filter membrane and guarantee that bacterium is trapped on the filtering membrane.

Be carved with containing mark line 7 on the cup 1, can reflect the capacity of cup liquid intuitively.

Reliability during for the stopping property that guarantees cup and liquid filtering, following filtering membrane 9 is welded on the cup 2 by the hot weld membrane process, and cup 1 and cup 2 are by heating means or ultrasonic method welding.
