AI Technical Summary

Technical Problem

Existing sampling and preservation devices for finless porpoise gut microbiota are difficult to use and have poor sealing, resulting in low detection accuracy. Impurities in the river water interfere with the detection, and poor fecal preservation affects the subsequent detection results.

Method used

A device comprising a storage cylinder, a cover plate, a sampling sleeve, and a sampling mechanism is designed. The sampling mechanism enables convenient sampling through a drive rod and a scraping component. A sealing ring and a desiccant are installed inside the storage cylinder to ensure the sealing and dryness of the sample.

Benefits of technology

It reduces the difficulty of sampling, prevents contamination from external impurities, keeps feces moist, and improves detection accuracy and the practicality of the device.

Abstract

The present application relates to the technical fields of sampling and storage device for finless porpoise intestinal flora determination sample, and provides a finless porpoise intestinal flora sampling and storage device, which comprises a storage cylinder and a cover plate for plugging the storage cylinder, a sampling sleeve is fixedly installed in the storage cylinder, the cover plate is provided with a fixing assembly for fixing connection between the cover plate and the storage cylinder, a storage sealing ring is arranged on the outer portion of the storage cylinder and is in mutual resistance with the cover plate, a sampling mechanism for extracting the feces of finless porpoise is arranged in the sampling sleeve, the sampling mechanism comprises a driving rod which is slidingly installed in the sampling sleeve and slidingly extends to the outer portion of the storage cylinder at one end. The sampling operation of the feces of finless porpoise is realized through the cooperation of the sampling mechanism, the sampling difficulty of the feces of finless porpoise is reduced through the cooperation of the sampling head, the driving rod and the scraping assembly, and in addition, the setting of the storage sealing ring and the sampling sealing ring can effectively prevent foreign matters from entering the inside of the storage cylinder to contaminate the sample, which is conducive to the promotion of the equipment.
