A human-computer interactive virtual simulation uterine cavity packing model and its application method

Abstract

The invention proposes a human-computer interaction virtual simulation uterine cavity packing model and a use method thereof. The model includes a sub-model of the basic structure of the human body, a sub-model of the vagina, a sub-model of the uterus, a development circuit board and an expansion interface; the sub-model of the uterus, the development circuit board and the expansion interface are fixed on the sub-model of the basic structure of the human body; connected to a computer terminal. Start the development circuit board, and the automatic inflation device fills the hollow silica gel attached to the outer surface of the uterus model with filler; multiple pressure sensors detect the pressure value applied to the silica gel surface; judge by the pressure software matching system configured in the computer terminal Whether the pressure value exceeds a predetermined pressure threshold; if so, a warning is issued through the computer terminal. By giving corresponding feedback to the user's operation, the technical solution of the present invention can help the user to practice the operation technique, operation angle, and equipment consumption, and improve the effect of model practice.

Description

technical field [0001] The invention belongs to the technical field of medical teaching, and in particular relates to a human-computer interaction virtual simulation uterine cavity packing model and a using method thereof. Background technique [0002] Lumen packing is the most traditional method of hemostasis, and there are two ways of packing, balloon and gauze. Balloons are often used for patients with bleeding after vaginal delivery, and gauze is often used for uterine packing in patients with cesarean section. Intrauterine gauze packing is mostly used for patients with shallow placenta accreta and local bleeding. [0003] Uterine cavity packing gauze control postpartum hemorrhage is a relatively primitive method of hemostasis, which belongs to the packing compression hemostasis method in surgical hemostasis methods, and is widely used in clinical work. However, filling the uterine cavity is a very cautious thing, and it will cause disaster if you are not careful. The...

Problems solved by technology

[0006] The inventors have found that when performing model manipulation experiments with similar schemes in the prior art, because the existing models only restore the most basic shape and structure of human organs, they cannot simulate the actual physiological reactions or symptoms of patients when they actually perform practical operations on patients. This makes it difficult for medical students to get effective practical practice on key operating techniques such as operating techniques, operating angles, and equipment usage when performing experimental operations on the medical model, which limits the teaching effect
