Fetus four-step palpation simulation system and method based on VR technology

Abstract

The invention relates to a fetus four-step palpation simulation system and a fetus four-step palpation simulation method based on the VR technology. The system comprises a palpation simulation human body device, a controlling and sensing unit, an upper computer and a VR virtual helmet, wherein the palpation simulation human body device comprises a palpation platform, a shell arranged on the normal delivery platform and having the appearance simulating the appearance of the upper half body of a pregnant woman, and man-made simulated abdomen skin covering the abdomen part of the shell; a simulated fetus platform and a simulated uterus arranged on the simulated fetus platform are arranged in a cavity of the abdomen of the shell, a simulated fetus is arranged in the simulated uterus, and the simulated uterus is filled with liquid serving as amniotic fluid; a steering engine is arranged at the position, corresponding to the abdomen of the shell, on the palpation platform, and drives the simulated fetus platform to horizontally rotate through a steering engine rotary table connected with an output shaft of the steering engine, and thus the head direction of the simulated fetus in the simulated uterus is adjusted; the controlling and sensing unit comprises a controller as well as a distance sensor and a gesture sensor which are connected with the controller. According to the system and the method, through the high-biofidelity simulation of the virtual four-step palpation, the operation simulation people realize the four-step palpation experiencing and training visually, and the system and the method have great application values for the four-step palpation training for medical students and corresponding nursing staff.

Description

technical field [0001] The invention relates to a four-step fetal palpation simulation system and method based on VR technology. Background technique [0002] The four-step palpation is to judge the fetal birth type, fetal presentation, fetal position, whether the fetal presentation is connected, whether the size of the uterus is consistent with the gestational age, and estimate the size of the fetus and the amount of amniotic fluid. However, due to the current awareness of doctor-patient diagnosis and treatment and the development of medical ethics, it is obviously inappropriate for medical students and related nursing staff to directly perform four-step palpation training simulation on pregnant women; and The existing four-step palpation device is difficult for trainers to obtain a highly simulated experience. [0003] Therefore, this application proposes a four-step fetal palpation simulation system and method based on VR technology. Through the simulation of highly simu...
