Embodiment
The utility model embodiment is described in detail with reference to specific embodiment.
As shown in figure 1, the utility model discloses a kind of culture medium taking device, including medium bottle 12, in the training
To support and be provided with culture medium bottle cap 9 on base bottle 12, culture medium bottle cap 9 be located in the opening of medium bottle 12, and to medium bottle 12
Sealed.
The culture medium connected inside and outside the medium bottle is provided with the culture medium bottle cap 9 and takes pipe, the culture
Base takes pipe one end and is arranged on the bottom of medium bottle 12, and the other end is arranged on outside the medium bottle and is provided with pressure and takes
Liquid device, the culture medium between the pressure liquid extraction device and the culture medium bottle cap 9 are taken on pipe, are provided with drain pipe 6,
Culture medium between the drain pipe 6 and the culture medium bottle cap 9, which is taken, is provided with check valve 7 in pipe.In the culture medium
The culture medium inside bottle 12 takes tube end and is provided with imbibition nozzle 11.
As shown in Fig. 2 the pressure liquid extraction device includes the compressed gas taken tube end sealing with the culture medium and connected
Capsule 2, I-shaped pressing lever 1 is provided with above the compressing gasbag 2, is provided with the outside of compressing gasbag 2 outside air bag
Shell 4, inside the air-bag shell 4, back-moving spring 3 being provided with, the back-moving spring 3 is set in the outside of compressing gasbag 2,
Described one end of back-moving spring 3 is connected with the end of pressing lever 1, and the other end is connected with the inner bottom surface of air-bag shell 4.
The culture medium take pipe include being arranged on liquid storage pipe 5 between the compressing gasbag 2 and the check valve 7 and
The rubber tube 10 of the lower section of check valve 7 is arranged on, is connected between liquid storage pipe 5 and rubber tube 10 by rubber interface tube 8.Liquid storage
Pipe 5 is tightly connected with compressing gasbag 2.
Wherein, the part selection such as pressing lever 1, air-bag shell 4, liquid storage pipe 5, drain pipe 6, rubber interface tube 8 is hard
Plastic material.All parts of the present apparatus can carry out high-temperature sterilization.
During use, rubber tube 10 is connected by user with rubber interface tube 8, and culture medium bottle cap 9 is placed on culture medium
