Detailed Description

The invention is further described with reference to the following figures and examples.

as shown in the figure, the medicine detection, filtration, bacteria collection and cultivation integrated device comprises an isolation operation bin 1 consisting of a bin body 101 and a bin door 102, wherein an operating hand inlet 2 is arranged on the bin body or the bin door, and an operating glove 3 is connected to the operating hand inlet.

The isolation operation storehouse is internally provided with a bacteria collection filter, the bacteria collection filter comprises a filter bowl 4, a liquid collection cup 5, a filter membrane 6 arranged between the filter bowl and the liquid collection cup and a support 7 detachably connected with the liquid collection cup, in the embodiment, the bottom of the liquid collection cup is provided with a rectangular insertion rod 8, and the liquid collection cup is inserted on the support through the rectangular insertion rod, so that the assembly and disassembly are convenient. An annular groove is formed in the opening of the liquid collecting cup, the filtering membrane is arranged in the annular groove, the top surface of the filtering membrane is higher than the end surface of the annular groove, and a liquid outlet 9 is formed in the bottom of the liquid collecting cup; the bottom of filter bowl sets up and collects liquid cup oral area complex tang in, tang and the oral area threaded connection of collection liquid cup in, and under tang and the oral area connected state of collection liquid cup including, the bottom of tang presses and forms seal structure on filtration membrane's limit portion, can avoid the problem that liquid flows from the fit clearance in filtering process.
