A small biological sample capture container and its use method

Abstract

The invention belongs to the technical field of animal capture, in particular to a small-sized living body sample capture container and its use method, comprising a bottom cover and a closure module screwed to the bottom cover; the closure module comprises an inner cylinder and an outer cylinder The wall thickness of the inner cylinder is provided with a plurality of sieve holes two; the bottom of the bottom cover is screwed and connected with the inner cylinder, and the outer side of the inner cylinder is movably socketed with the outer cylinder; in the present invention, The first capture box, the second capture box and the third capture box are arranged on the inner side of the inner cylinder, and the first capture box, the second capture box and the third capture box can be used to isolate and capture small organisms in different soil layers, In addition, the inflatable airbag is connected with the telescopic rod so that there is a gap between the inner cylinder and the side wall of the foundation pit, which is convenient to pull out the whole body through the handle and improves work efficiency. Soil, improve the similarity between the environment in multiple capture boxes and the soil environment, and effectively improve the capture efficiency of small animals.

Description

technical field [0001] The invention relates to the technical field of animal capture, in particular to a small-sized living body sample capture container and a method for using the same. Background technique [0002] When small organisms are studied, it is usually necessary to capture small animals alive—as a sample for researchers to study, so as to study the living habits of small organisms. Because the living environments of small organisms are different, and there are many types of small organisms in soil and water, researchers need to often carry native organism capture devices and aquatic organism capture devices to capture small organisms in the two living environments. . [0003] However, when catching small organisms, most of them are in the wild environment, so researchers carry a large number of capture devices, and when working in the field, the pressure is high, and a large number of tools need to be carried, and the physical strength of the researchers will i...

[0003] However, when catching small organisms, most of them are in the wild environment, so researchers carry a large number of capture devices, and when working in the field, the pressure is high, and a large number of tools need to be carried, and the physical strength of the researchers will inevitably decline. When capturing native organisms, it is often necessary to dig a foundation pit, and then bury the native organism capture device, which is inconvenient to take out the device, and when capturing aquatic organisms, it is necessary to hang heavy blocks to ensure the stability of the device in the water, thereby increasing Increased the workload of researchers, and it is not convenient to capture many different types of small organisms
