Intravenous infusion training system based on VR platform

Abstract

The invention provides an intravenous infusion training system based on a VR platform. The system comprises a control host, a display device, a force feedback device and a foot-operated device. The control host is electrically connected with the display device, the force feedback device and the foot-operated device. The display device is used for displaying a venous blood sample acquisition model. The force feedback device is used for sending a first control signal to the control host according to operation of a user so as to carry out intravenous infusion simulation operation on a venous blood sample acquisition injection arm, and receiving feedback information of the control host to carry out force feedback on the user. The foot-operated device is used for sending a second control signal to the control host according to the operation of the user so as to carry out auxiliary operation on the intravenous infusion simulation operation. According to the invention, the intravenous infusion training system is achieved based on the virtual reality technology, so a problem of failure to carry out repeated trainings on invasive experiments in experiment teaching is solved; problems of poor simulation ability, incapability of resisting repeated puncturing, liquid leakage and mildewing of a current model are solved; and the provided system is an innovative and valuable supplement to current teaching modes.

Description

technical field [0001] The invention relates to the field of virtual reality technology, in particular to an intravenous injection training system based on a VR platform. Background technique [0002] Intravenous injection technique is one of the operating techniques that nurses must master. [0003] At present, there are two experimental teaching methods, one is real-life practice among nursing students, and the other is practicing on models. The first teaching method has the following problems: ① Intravenous injection is an invasive experiment, and it is impossible to train repeatedly on real people; ② Nursing students have not yet obtained nurse qualification certificates, so practicing on real people is contrary to ethical principles. The second teaching method has the following problems: ① The simulation of the solid silicone arm model is poor: the real blood vessels branch from the centripetal end to the distal end from thick to thin, while the model blood vessels use...
