Problems solved by technology

The disadvantages are: 1. The detection object cannot be designed according to the needs of teaching
2. It is difficult to compare the causal relationship between sonograms and tissues
Ultrasonic detection images based on the human body cannot be compared and observed with the original tissue, and the teaching effect is not ideal
3. Inconvenient and unsightly to operate
Male and female students share the same room, with their chests exposed and their abdomens exposed, and it is cold in winter. It is inconvenient and unsightly to use the human body as the test object

Embodiment Construction

[0019] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0020] Materials used to make this model include: plaster of paris bandages, mock liver model, agarose, human silica gel, colorants, and distilled water.

[0021] The plaster of paris bandage is used to make the female model of the simulation model shell: add a small amount of distilled water to the plaster of paris bandage to make the gypsum powder in it into a sticky paste, and tighten the plaster of paris bandage on the lower half of the liver solid model (the opening on the upper part is easy to take out ), after standing to dry naturally, the plaster bandage is hardened and formed, and the plaster model is removed to be the female mold.

[0022] Agarose is the main material for making simulation models. Take agarose solid powder of different qualities, add distilled water to dissolve, and prepare agarose solutions with different concentrati...

Abstract

The invention discloses a production method and application of an abdominal organ teaching simulation model applicable to type-B ultrasonic detection. The model is made of agarose solutions of different concentration. The model is applicable to type-B ultrasonic detection teaching experiments, convenient, visualized and convincing, and shapes of real organs can be seen directly.

Description

technical field [0001] The patent of the present invention relates to a teaching simulation model, in particular to a preparation method and application of an abdominal organ teaching simulation model that can be used for B-ultrasound detection. Background technique [0002] Medical ultrasound imaging technology has become an irreplaceable imaging diagnostic technology in medical imaging due to its advantages of non-ionizing radiation and high identification of soft tissues. The basic principle of ultrasonic imaging is: when ultrasonic waves with a certain frequency propagate in human tissues, they pass through the multi-layer interfaces of different organs and different tissues. Due to the differences in the acoustic impedance of different tissue interfaces, the ultrasonic waves will be reflected to different degrees or / and scattering. The echoes formed by these reflections or scattering contain the acoustic information of the different tissues that the ultrasound passes t...
