Bacterial microorganism detection sample liquid extraction device

Abstract

The invention discloses a bacterial microorganism detection sample liquid extraction device. By cooperation of an inner rotating disc and an outer rotating disc, bacterial microorganism sample liquidis extracted, and efficiency in extraction of the bacterial microorganism sample liquid can be effectively improved. The device is characterized in that the bottom end of a body barrel is in an open structure, and the top end of a connection barrel is connected with the bottom end of the body barrel through a connection sleeve; the top end of the connection barrel is in an open structure and communicated with the body barrel, the bottom end of the connection barrel is in an open structure, a discharging hopper is arranged at the bottom end of the connection barrel and communicated with the connection barrel, an end cover is arranged on the discharging hopper, and the inner wall of the body barrel is provided with a spiral guide groove; the wall of the body barrel is provided with a feedingport, the diameter of the feeding port is gradually increased from an inlet to an outlet, a feeding hopper is arranged on the outer wall of the body barrel and communicated with the feeding port, anda guide sleeve is arranged in the middle of the top end of the body barrel.

Description

technical field [0001] The invention relates to a device for extracting sample liquid for detection of fungi microorganisms, which relates to a device used in biological engineering for extracting sample liquid when fungi microorganisms are detected, and belongs to the field of bioengineering. In particular, it relates to a device for extracting a sample liquid of a fungus microorganism sample through the cooperation of an inner turntable and an outer turntable. Background technique [0002] At present, in the field of biomedicine, fungi such as Tremella, Ganoderma lucidum, Hericium erinaceus, etc. are widely used as raw materials for medicine because of their edible and medicinal properties. Before production, it is usually necessary to detect and analyze the fungi. Its components, usually need to grind and pulverize the fungus samples during testing, and extract the sample liquid for laboratory analysis. The traditional method is to use knife cutting to break the sample, a...

[0003] Publication No. CN201803870U discloses a split sampler for an ultrasonic pulverizer, comprising a sampling cup and an upper sealing cover that is hermetically connected to the sampling cup, and a split sampling tube with a slight degree is penetrated on the upper sealing cover, and the split sampling tube and the upper sealing cover The sealing covers are sealed, and the upper port of the diversion sampling tube is provided with a diverter valve, and the other interface of the diverter valve is connected to the diverter sampler interface provided on the return pipe on the ultrasonic pulverizer. When using this device for fungus detection and sampling, the sample liquid and The crushed fungi are mixed together, which is easy to block the sampling tube. It is necessary to filter the crushed matter before extracting the sample liquid, which affects the detection efficiency and the use effect is not good.
