Full automatic vena epigastrica blood flow direction inspection standardized patient

Abstract

The invention relates to the medical education technical field, and specifically refers to a full automatic vena epigastrica blood flow direction inspection standardized patient comprising high simulation human body models, a controller, a solenoid valve, a one way valve, a miniature blood circulating pump, and a blood storage bottle; the features are that belly walls of four high simulation human body models are respectively provided with a normal elder people belly wall vein, a belly wall vein with a blocked vein upper cavity, a belly wall vein with a blocked vein lower cavity, and a belly wall vein with a blocked portal vein; the embodiment 2 is that four vena epigastrica of different physical signs and internal structures are assembled in a model drum with equal belly distention diameter; a single chip can control to set different physical signs, so operation is simple and automation level is high; selection buttons of the controller can be controlled so as to automatically set physical signs, and automatic voice prompt can be realized; the full automatic vena epigastrica blood flow direction inspection standardized patient is simple in operation, vivid in simulation effect, suitable for medical students and medical personnel to carry out vena epigastrica blood flow direction inspection skill training and examination, thus obviously improving teaching effect.

Description

technical field [0001] The invention relates to the technical field of medical education equipment, in particular to a standardized patient for fully automatic abdominal wall venous blood flow direction inspection. Background technique [0002] The abdominal wall veins of normal people are generally not clearly visible. In thinner and fairer-skinned people, the abdominal wall veins are often faintly visible; in the elderly with thin and loose abdominal skin, they are more easily seen and can protrude from the skin, but the number of veins is not large. Many, not distended and distended, without pathological significance, when the portal vein or superior and inferior vena cava reflux is obstructed to cause side limb circulation, the abdominal wall veins can be significantly expanded or distorted, which is called abdominal wall varicose veins; check the presence of abdominal wall varicose veins The direction of blood flow is helpful to determine the location of venous blockage...

Problems solved by technology

[0002] The abdominal wall veins of normal people are generally not clearly visible. In thinner and fairer-skinned people, the abdominal wall veins are often faintly visible; in the elderly with thin and loose abdominal skin, they are more easily seen and can protrude from the skin, but the number of veins is not large. Many, not distended and distended, without pathological significance, when the portal vein or superior and inferior vena cava reflux is obstructed to cause side limb circulation, the abdominal wall veins can be significantly expanded or distorted, which is called abdominal wall varicose veins; check the presence of abdominal wall varicose veins The direction of blood flow is helpful to determine the location of venous blockage; the method of checking the direction of blood flow: the doctor puts the index finger and middle finger together, compresses a section of varicose vein that is not bifurcated, pushes the blood to both ends to make the blood vessel empty, and then lifts a section alternately. Refers to the direction of blood flow can be judged by observing where the blood flows in to fill the blood vessels. The traditional teaching method is theoretical teaching supplemented by pictures or videos. Because of this teaching method, students can't do it by themselves, so they still don't understand deeply. , skills training can only be carried out on patients in teaching hospitals. Since there are too few typical patients to meet the needs of teaching, there is currently no simulation teaching equipment for skill training in abdominal wall vein blood flow direction inspection in the world.
