A kind of Bacteria Detection equipment of the utility model, including mark room, the mark interior is loaded with fluorescent dye, described The side of mark room is connected with Sample Room, and the junction of the Sample Room and mark room is fixed with dividing plate, the Sample Room it is another Side connects collecting chamber, and the bottom of the collecting chamber is equipped with filter paper, and the junction of the collecting chamber and Sample Room is fixed with Removable cover is stamped at filter membrane, the top of the collecting chamber and Sample Room, and the opposite side of the collecting chamber is connected with sensing chamber, institute The side for stating sensing chamber is provided with biology sensor, chemical sensor and optical sensor, and the sensing chamber and collecting chamber Junction is fixed with film.

As a kind of optimal technical scheme of the present utility model, the fluorescent dye is fluorescence quantum.

As a kind of optimal technical scheme of the present utility model, the filter membrane is hollow-fibre membrane.

As a kind of optimal technical scheme of the present utility model, the film is Caco-2 type cell membranes.

It is used as a kind of optimal technical scheme of the present utility model, the biology sensor, chemical sensor and optical sensing It is indoor that the probe of device is arranged at detection.

The beneficial effect that the utility model is reached is：Set by setting mark room, and between mark room and Sample Room Bacterium can be marked for the fluorescent dye put in filter membrane, mark room, then by detecting the fluorescence volume on filter membrane, energy The bacterial number that enough preresearch estimates go out in sample；Film is set between Sample Room and collecting chamber again, bacterial secretory can be made Material passes through, then by the species of various sensor Preliminary detection bacteriums, and quickly judges that food quality detection is It is no qualified；Filter paper is set in collecting chamber again, the bacterium in collecting chamber can be taken out, then further culture, accurately Understand the bacteria's numbers and species in food.

Embodiment

Preferred embodiment of the present utility model is illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein excellent Select embodiment to be merely to illustrate and explain the utility model, be not used to limit the utility model.

Embodiment：As shown in Figure 1-2, a kind of Bacteria Detection equipment of the utility model, including mark room 1, mark are contained in room 1 Equipped with fluorescent dye 13, the side of mark room 1 is connected with Sample Room 2, and Sample Room 2 and the junction of mark room 1 are fixed with dividing plate 12, the opposite side connection collecting chamber 3 of Sample Room 2, the bottom of collecting chamber 3 is equipped with filter paper 4, and the company of collecting chamber 3 and Sample Room 2 The place of connecing is fixed with filter membrane 11, and removable cover 14 is stamped at the top of collecting chamber 3 and Sample Room 2, and the opposite side of collecting chamber 3 is connected with Sensing chamber 5, the side of sensing chamber 5 is provided with biology sensor 6, chemical sensor 7 and optical sensor 8, and sensing chamber 5 is with receiving The junction of collection room 3 is fixed with film 10.

Fluorescent dye 13 is fluorescence quantum, and bacterium can be marked.

Filter membrane 11 is hollow-fibre membrane, and bacterium and bacterial secretory thing can be made all to be filled into collecting chamber 3.

Film 10 is Caco-2 type cell membranes, and bacteriological filter can get off, and bacterial secretory thing is entered by film and examines Survey in room 5.

The probe 9 of biology sensor 6, chemical sensor 7 and optical sensor 8 is arranged in sensing chamber 5, can be to thin Bacterium secretion is detected.
