Abstract

The utility model relates to a culture device for anaerobic bacteria, characterized in that the culture device for anaerobic bacteria adopts two ordinary glass culture dishes used for polishing the dish inlet end to a plane ground glass shape; a reaction disk for storing reagent that can be arranged in the culture dish is arranged in the culture device for anaerobic bacteria, and the reaction disk is provided with holes used for storing agent and test paper. When used, one dish is inoculated, and the other dish is arranged in the reaction disk. The dish port end faces on two dishes are homogeneously coated with vacuum grease, and the dish port end faces are closely contacted through closing two dishes without gas leakage.

Description

Culture device for anaerobic bacteria

The utility model relates to a kind of device of cultivating anerobe.

The device of existing both at home and abroad simple and easy cultivation anerobe mainly contains anaerobism airbag and anaerobic jar.The anaerobism airbag is because seal degree poor (clamping sack with clip) usually leaks gas and is easy to and pollutes, and effect is undesirable.Anaerobic jar and lid thread connection are added the sealing-ring screwing hermetic, will put into the oxygen consumption agent in the jar during use, inoculation good culture dish or test tube are placed in the jar again, screw sealing of lid, and it has following shortcoming: 1. the easy aged deterioration of sealing-ring, so that gas leakage; 2. the lid screw thread easily is worn so that covers and tightly leaks gas; 3. the big oxygen consumption agent of jar volume causes waste, and anaerobic environment and culture dish can not combine together in addition, so carry inconvenience, clinical collect specimen is directly arrived in inconvenience, carries out the cultivation of anerobe.

The purpose of this utility model provides a kind of good seal performance, anaerobic environment and culture dish and is integrated, portably uses convenience, little, the cheap anaerobic bacteria culture device of volume.

To achieve these goals, the utility model has adopted time routine technical scheme: adopt two common culture dish, the ware mouth end face of each culture dish is worn into the plane ground-glass appearance, the plane ground end face of two wares can closely be contacted do not reveal the slit, also be provided with a reaction tray of depositing reagent, it can put into arbitrary culture dish, on reaction tray, be provided with three blind hole and grooves of depositing test paper of depositing reagent, have groove between one of them blind hole and other two blind holes and communicate, and channel bottom is an inclined plane shape.

Owing to adopted technique scheme, make the utility model compared with the prior art have routine advantage down: 1. good sealing effect, on the ground end face, coat vacuum grease, after covering, two wares can keep sealing condition (bimester more than) for a long time; 2. anaerobic environment and culture dish are integrated, so dexterity easy to use can be carried clinical inoculation; 3. the oxygen consumption agent consumes fewly, cheaply is easy to popularize use.

Routine accompanying drawing provides a most preferred embodiment of the present utility model down.

Description of drawings:

Fig. 1 is a front view of the present utility model;

Fig. 2 is a vertical view of the present utility model, removes culture dish 1;

Fig. 3 is single culture dish 2.

Below in conjunction with accompanying drawing embodiment of the present utility model is described specifically.

Culture dish 1,2 is normally used glassware, and its dimensional structure is identical, as shown in Figure 3.The end face 7 of culture dish is the plane ground-in, be ground-glass appearance, so that the ground end face can closely contact and do not reveal the slit when two culture dish are lumped together, as shown in Figure 1, place a reaction tray 3 of depositing reagent in culture dish 2, its material can be glass, synthetic glass or plastics.On reaction tray 3, have the blind hole 4,6,8 of three store reagents, have the groove 5 that identical bottom surface is the inclined-plane between blind hole 6,8 and the blind hole 4, the groove inclined-plane is towards blind hole 6,8 direction height, low towards blind hole 4, blind hole 4 is communicated with blind hole 6,8, on reaction tray 3, also have a groove 9 of depositing test paper.

Using method of the present utility model is as follows, with injecting some water in the blind hole 4 of reaction tray 3, puts into oxygen consumption reagent respectively (as sodium borohydride NaBH in the blind hole 6,8 earlier ₄, sodium bicarbonate NaHCO ₃Deng) to put into test paper in the groove 9 stand-by.Culture dish 1 is put into substratum and inoculated sample, evenly coat vacuum grease on the ground end face with culture dish 1,2 then, again reaction tray 3 is put into culture dish 2, culture dish 1 is covered on culture dish 2, the ground end face 7 that makes them closely contact and a little firmly rotates, then the two wares enclosed space of long-term air tight formation of combining closely.Then a bit culture dish 1,2 a little inclination, water in the blind hole 4 is flowed in the blind hole 6,8 along groove 5, then the reagent react in water and this two blind hole produces hydrogen, carbonic acid gas or the like gas, the clear consumption of oxygen in the culture dish is done to the greatest extent, and provided an adapt circumstance for the growth of anerobe.

Claims

1, a kind of anaerobic bacteria culture device, it comprises two common culture dish, the ware mouth end face that it is characterized in that each culture dish is the plane ground-in, the ground end face can closely contact air tight when two wares were closed, be provided with a reaction tray of depositing reagent in this device, it can put into arbitrary culture dish.

2, anaerobic bacteria culture device according to claim 1 is characterized in that being provided with on the described reaction tray three blind hole and grooves of placing test paper of depositing reagent, has the inclined-plane groove between one of them blind hole and other two blind holes and communicates.
