1. The simulation model is made from advanced materials with correct anatomical
positions, soft and eslastic skin, true feeling and real pathological tissue.
2. Penetrate into median fornix posterior, which is 1cm inferior to the joint of cervix
and vagina mucosa, parallel to cervical canal with a No.7 puncture needle, and light
red liquid extraction means successful centesis.
3. If puncture isn’t operated according to the conventions, e.g. if the operated pierces
into the rectum, there will be yellow liquid extraction, which shows puncture failure.
4. If operator doesn’t insert the needle according to the convention but pierces
bilaterally without destination, it will hurt surrounding organs, which shows puncture
failure.
