Abstract
The utility model discloses a bacteria cultivation apparatus used for an aseptic test. The utility model comprises a shell body and a bacteria cultivation incubator, wherein, a bracket is arranged on the shell body, samples to test are fixed on the bracket, a peristaltic pump is arranged between the samples to test and the bacteria cultivation incubator, and the samples to test, the peristaltic pump and the bacteria cultivation incubator are connected through pipelines; a pump head structure which is composed of a pump cover board, a motion block and a locator card is arranged on a pump seat of the peristaltic pump. The utility model has the functions of taking in samples and cultivating and incubating bacteria, and can carry out the operation of pressure filtration and bacteria cultivation under a totally enclosed condition.
Description
The utility model relates to a kind of instrument, especially relates to a kind of instrument that is used for the pharmaceuticals steriling test.
What the pharmaceuticals steriling test adopted usually at present is that method is that the membrane filter that will filter membrane be housed is connected with off-gas pump, utilize pneumatics that sample to be checked is filtered the collection bacterium, microorganism-collectings such as the bacterium that sample is contained, fungi are on filter membrane, then filter membrane is transferred in the substratum and cultivates, whether last check sample has bacterium.The problem that adopts this method to exist is: 1, complex operation takes length.2, checkout procedure is opened wide, and is subject to exogenous pollution.3, during the pbz polymer liquid filtering, produce a large amount of bubbles, easily suck in the off-gas pump.
The inventor discloses a kind of colony culture device that the collection bacterium is also cultivated therein that is used to filter at the ZL95203829.3 utility model patent.The colony culture device shell adopts transparent material to make, and has designed two four-way structures, and three colony culture devices can evenly filter simultaneously, and all there is a ventilation mouth each incubator top, is beneficial to microorganism growth, can prevent outside contamination again.Colony culture device can be used with peristaltic pump or negative pressure pump, is applicable to pressurization or filtration under diminished pressure collection bacterium.Filtration finishes, and sucks substratum, can carry out microbial culture.
The purpose of this utility model provides a kind of collection sample introduction, collects bacterium, is incubated at one, carries out the germ collector of pressure filtration collection bacterium under totally-enclosed condition.
In order to achieve the above object, the solution that the utility model is taked is: a kind of germ collector, comprise a housing and the colony culture device that is positioned on the housing, housing is provided with support, testing sample is fixed on the support, one peristaltic pump is set between testing sample and colony culture device, utilizes pipeline that testing sample is sent into colony culture device by peristaltic pump; Be provided with pilot circuit in the housing, its control panel is positioned on the housing; The pump seat of described peristaltic pump is provided with the pump head structure of being made up of pump closure, motion block, locator card; Also be provided with sump pit and waste liquid vent pipe on the housing.Support is pressed from both sides and is formed by pole, slide block, year bottle ring, pressure bottle; Housing is provided with the socket of mounting bracket.
Owing to utilize pump line that testing sample is sent into colony culture device by peristaltic pump in the above-mentioned solution, directed creeping effect by peristaltic pump, liquid is continuously pushed in the airtight filter, under totally enclosed condition, implement pressure filtration, make sample introduction, collect bacterium, be incubated at one, avoid the exogenous pollution in the testing process to greatest extent, pilot circuit is in order to the velocity of rotation of control peristaltic pump, with control filter filtration velocity, sump pit and waste liquid vent pipe make the entire operation process very easy in order to discharging depleted liquid.
