Description

Disposable use monoblock type filtering culturing dish

Technical field

The utility model provides the device of the filtering culturing dish (being called again: bacteria gathering device, filtration bacteria gathering device) in a kind of medicine inspection product verifying attachment, the especially verifying attachment.

Background technology

According to China's officinal regulation, need carry out steriling test to the medicine of producing, the special-purpose filter of  0.45u aperture filter membrane is equipped with in employing, after it is filtered, bacterium contained in the medicine is left on the filter membrane, cultivates at the adding nutrient solution, simultaneously, need set up the positive and negative control, can whether be made correct evaluation in process of production to tested medicine like this by bacterial contamination.And finish the employed special-purpose filter of above-mentioned process is exactly filtering culturing dish.The filtering culturing dish device, comprise two or three filtration culture tank, filtering culture tank is an airtight cylindrical shell, is provided with spout (spout is linked to each other by plastics tubing), venting port at an upper portion thereof, be provided with leakage fluid dram in its underpart, the filter membrane in  0.45u aperture is housed in jar.In actually operating, two or three to be filtered culture tank and be separately fixed on the fixed position of operator's console, will filter duplex or three conduits that the culture tank spout links to each other, be connected respectively on the sample bottle to be checked with each.According to the operation steps of cleaning, injection sample to be checked and collection bacterium, the venting port on alternative sealing and the unlatching bacteria gathering tank is finished many checking procedures such as fluid injection, discharge opeing and pressure filtration so that the interior suitable air pressure of jar to be provided in operating process.

In the prior art, filtering culture tank is single absolute construction, need filter culture tank with two and three during use and fix singly on the worktable, also will take off worktable seriatim behind the collection bacterium, puts into bacteriological incubator.One like this filtration culture tank structure installs, dismantles cumbersome in use one by one; If accidentally, the bacteria gathering tank that also may occur is not on the same group put mixed phenomenon, makes check pseudo-result occur and fails.In the process of moving filter culture tank to the incubator, existing structure makes operator often lift the remaining conduit that connects on spout and the venting port, like this, conduit and spout and venting port are thrown off, it is contaminated to cause the filtration culture tank to be exposed in the air, causes detecting failure.

Existing structure positions because be difficult to for cooperating the corresponding apparatus upgrading that certain obstacle is arranged.

Summary of the invention

The purpose of this utility model is to improve deficiency of the prior art, and a kind of filtering culturing dish that is easy for installation and removal is provided, and is difficult for causing confusion, being convenient to filtration filtering culturing dish device mobile and that can cooperate the location use of instrument.

The purpose of this utility model is achieved in that

The filtration filtering culturing dish device that the utility model provides comprises that pedestal and several filter culture tank,

The upper top of each described filtration culture tank is provided with spout and venting port, its bottom is provided with leakage fluid dram, described filtration culture tank is installed in and forms the monoblock type filtering culturing dish on the described pedestal, is provided with corresponding leakage fluid dram on the pedestal at corresponding each leakage fluid dram place, described filtration culture tank bottom.

According to survey requirement, described filtration culture tank is generally triad or two one group use, an optimal technical scheme that sets firmly structure of itself and described pedestal is: this filtration culture tank and pedestal constitute removable fixed sturcture, on this pedestal, be provided with corresponding fixing position, for example be provided with draw-in groove or Ka Keng on described pedestal, described filtration culture tank is fastened in this draw-in groove or the card hole fixing.Another optimal technical scheme of filtering the fixed sturcture of culture tank on the described pedestal is: described filtration culture tank is fixed on this pedestal non-dismountablely and forms integrative-structure.

Corresponding culture tank and the dismantled and assembled fixed sturcture of pedestal of filtering can be provided with three described fixing positions on the described pedestal.When needing in operation to use two to filter culture tank, only therein two fix in the position card and establish two and filter culture tank.Certainly, also can be provided with two described fixing positions on the described pedestal, provide to be only applicable to the two jars of needs that filter cultivation.

Similarly, corresponding culture tank and the non-disconnectable fixed sturcture of pedestal of filtering can be fixed three filtration culture tank and form three filtering culturing dish on the described pedestal, also can fix two and filter culture tank formation duplex filtering culturing dish.

In use, be that this filtering culturing dish device is fixed on the worktable with tank, inject the device of soup etc. being provided with spout on this filtration culture tank on this worktable, and the device etc. that opens and closes described venting port, this filtering culturing dish device need be fixed on the worktable.For this reason, on described pedestal, be provided with syndeton with worktable.

Described syndeton can be located at guide block that the fixed guide groove with on the worktable on the described pedestal is complementary or with the guide-track groove that fixed guide blocks on the worktable is complementary, also can be with worktable on the fixture block that is complementary of fixed card slot or the draw-in groove that is complementary with fixedly fixture block on the worktable.

In design, adapting to the two jars of width that filter the pedestal of this filtering culturing dish device of cultivating can be and three jars of identical or short two kinds of situations of base width of filtering the filtering culturing dish device of cultivating, owing to have syndeton between itself and the worktable, and in this syndeton, may have guide-track groove with the projection of pedestal coupling on the worktable, syndeton such as guide block or fixture block, and the syndeton of the projection on the worktable also has two groups, between the syndeton of corresponding three filtration culture tank, also be provided with the corresponding duplex of a row and filter the syndeton of culture tank, in order to make three filtering culturing dish device also can be fixed on such worktable easily, can be provided with sunk structure in its pedestal upper bottom portion corresponding position, be complementary with the outstanding syndeton of corresponding duplex on the worktable.

For the ease of taking and moving this filtering culturing dish device, can on this pedestal, be provided with the handle of taking.

The filtering culturing dish device that the utility model provides is integrated on the pedestal by several are filtered culture tank, make its person that in use is not convenient to operation on worktable, mount and dismount and filter moving of culture tank, and be difficult for causing different groups filtration the mixed of culture tank to put.Be convenient to mechanical means simultaneously to its requirement that positions.
