Embodiment 1

[0038] A method for making an early pregnancy diagnosis teaching model, comprising the following steps:

[0039] Step (1): making corresponding fetal bovine embryo models according to the body size data of fetal bovine embryos of different gestational ages; step (2): making corresponding fetal bovine embryo teaching models based on the above-mentioned fetal bovine embryo models, specifically including: step ( 2.1): Dissolve taro powder and water in a ratio of 1:2, then add 1% polyvinylpyrrolidone (PVP), and mix well to obtain the base material; Step (2.2): Pour the above-mentioned uniformly mixed base material into the fetal calf In the embryo model; step (2.3): Put the fetal bovine embryo model containing the base material into the water and stop heating when it reaches the gel state, and then take out the semi-finished fetal bovine embryo teaching model, wherein the heating temperature is 90 degree, 40 minutes;

[0040]Step (2.4): Put the above-made teaching model of fetal ...

Abstract

The invention provides a preparation method for manufacturing an early-stage pregnancy diagnosis teaching model. The method comprises the steps of (1) establishing a corresponding embryo model according to the body scale data of embryos of different gestational ages; (2) preparing a corresponding embryo teaching model on the basis of the embryo model; (3) placing the embryo teaching model into anisolation device with a first solution and integrally immersing into a containing device containing a second solution; (4) applying a coupling agent to a probe of a veterinary B-ultrasonic instrument, and immersing in a second solution of the containing device to observe the morphology of the embryo teaching model to simulate invitro early-stage pregnancy diagnosis. The early-stage pregnancy diagnosis of a cow is carried out through the early-stage pregnancy diagnosis teaching model of the invention, so that the pregnancy diagnosis of the cow can be advanced into 30 days after hybridization,and the non-pregnant rate is reduced. The waste of the forage grass resources caused by non-pregnant cows is reduced, the breeding efficiency is improved, and the industrial economic benefit is increased.

Description

technical field [0001] The invention relates to the field of teaching, in particular to a method for making and application of an early pregnancy diagnosis teaching model. Background technique [0002] B-ultrasound image diagnosis is to use the probe to emit high-frequency ultrasonic waves through the piezoelectric effect to penetrate into the body tissue to generate echoes. The echoes are received by the probe and converted into high-frequency electrical signals and then sent to the host. After amplification processing, they appear on the fluorescent screen. A modern imaging diagnostic technique of section tissue sonogram. As early as the mid-1970s, when B-ultrasound technology was successfully used in the pregnancy diagnosis of horses, it was hailed as a revolutionary change in veterinary diagnostic technology. Research the most far-reaching technological advances. At this stage, ultrasonic diagnostic technology, especially B-ultrasound imaging diagnostic technology, has...
