Teaching model for abdominal examination skill training during pregnancy

Abstract

The invention discloses a teaching model for abdominal examination skill training during pregnancy. The teaching model comprises a pregnancy abdomen phantom, wherein the pregnancy abdomen phantom can be fixed to the abdomen of a whole female body mode, a uterus phantom and a pelvis inlet phantom are arranged in the pregnancy abdomen phantom, a fetus phantom is arranged in the uterus phantom, and liquid is filled between the fetus phantom and the inner wall of the uterus phantom. A first microphone is arranged on the fetus phantom and used for playing fetal heart sound and umbilical cord sound, a second microphone is arranged on the uterus phantom and used for playing uterine souffle, placental souffle and aorta abdominalis souffle, and the first microphone and the second microphone are in signal connection with a player. A vibration device for simulating fetal movement is arranged on the fetus phantom and is in signal connection with the controller. The teaching model for abdominal examination skill training during pregnancy has the advantages of being simple in structure, good in simulation performance and good in teaching effect.

Description

technical field [0001] The invention relates to the technical field of medical teaching models, in particular to a teaching model used for training abdominal examination skills during pregnancy. Background technique [0002] The purposes of abdominal examination during pregnancy include: 1. Know the size of the uterus and estimate the amount of amniotic fluid in the uterus. 2. Understand fetal development and estimate fetal weight. 3. Understand the position of the fetus in the uterus (fetal position), and understand whether the fetal part enters the pelvis and the degree of pelvic entry. 4. Understand the frequency, rhythm, and sound intensity of the fetal heartbeat, and understand the differences between fetal heart sounds and umbilical cord murmurs, uterine murmurs, placental murmurs, and abdominal aortic murmurs. 5. Understand fetal movement counting. 6. Understand the use of fetal heart rate monitor. [0003] The functions of abdominal examination during pregnancy i...

Problems solved by technology

[0011] (2) In the current teaching model, the uterus is inflated to make the abdomen swell during pregnancy to achieve the effect of simulation. However, due to the gas filled in the uterus, the fetus will not float in the uterus, and it is impossible for students to experience The sense of floating of the fetus surrounded by amniotic fluid, such as: the feeling of floating ball of the fetal head, the feeling of pushing the carcass, and the feeling of being pushed when the fetus is not in the basin, can not make students perceive the amount of amniotic fluid

[0012] (3) It only puts a player in the fetal simulation body, which can only simulate the fetal heart sound, the sound is single, and the simulation is poor

Because the umbilical cord murmur, uterine murmur, placental murmur, and abdominal aortic murmur cannot be heard, students cannot be trained to distinguish fetal heart sounds from other murmurs

[0013] (4) There is no fetal movement, so it is impossible to train students in the training of fetal movement counting and the use of fetal electronic monitors.

[0014] Therefore, the existing teaching model has poor simulation performance, single function, and cannot achieve the ideal teaching effect, so its structure needs to be further improved
