Device for measuring forms of leeches and measuring method thereof

Abstract

The invention provides a device for measuring the form of a leech and a measuring method of the device. The device comprises a movable supporting frame, a camera clamping groove, a camera, a light supplementing lamp, miniature glass coordinate paper, a miniature glass clamping groove and a computer. The movable supporting frame comprises a bottom plate, a vertical support and a transverse support, the vertical support and the bottom plate are perpendicularly arranged and fixedly connected, the transverse support and the vertical support are movably connected, and the transverse support and the bottom plate are arranged in parallel; the camera clamping groove is formed in the transverse support, the camera is connected with the computer, the light supplementing lamp is arranged on the bottom plate, and the miniature glass coordinate paper is arranged on the bottom plate through the miniature glass clamping groove. The miniature glass coordinate paper comprises base glass paper, inclined plane glass paper and top glass paper. When the measuring device is used for measuring the form of the leech, the tiny form characteristics of the leech can be simply, easily and comprehensively observed, the form structures of different types of leeches can be distinguished, and a morphological basis is provided for leech classification and phylogenetic research.

Description

technical field [0001] The invention relates to the technical field of biological measurement equipment, in particular to a device for measuring the morphology of leeches and a measuring method thereof. Background technique [0002] Leeches, commonly known as leeches, belong to the class Annelida, and are widely distributed in streams, rivers, lakes, forests, fields, roadsides, and oceans in various water and land environments on the earth. They mainly feed on human bodies, The blood or body cavity fluid of livestock, poultry and wild animals, and some species live a predatory or saprophytic life, which has very important ecological significance in natural or artificial ecosystems. With the advancement of science and technology, the role of leeches in human social life is becoming more and more important. In particular, medical leeches, which are widely used in the medical field, provide a good example for the development and utilization of leeches. Hirudin, which is secret...

AI Technical Summary

Problems solved by technology

However, leeches are soft, flexible, and changeable in shape, so it is difficult to measure them in vivo, and the specimens soaked in alcohol or formalin have large differences due to the difference in storage time and concentration of the preservation solution. Measuring differences is also not conducive to comparative studies of shape and size between species
