Description

Technical Field

[0001] The present invention relates to the field of mixed reality training technology, and in particular to a children's venipuncture training system based on mixed reality technology. Background Art

[0002] Intravenous infusion is a basic skill in medical nursing. The key to intravenous infusion is the one-shot blood rate of the venous puncture technique. During puncture, the speed of the needle cannot be too slow, and the angle of the needle must be appropriate, neither too deep nor too shallow. Otherwise, the blood vessel may not be punctured, or the blood vessel may be punctured too deep, and the patient will feel pain. Experienced medical staff know that there will be a clear sense of failure after accurately puncturing the vein, and blood will return at the end of the intravenous infusion needle. To achieve one-shot blood, you can only practice repeatedly in normal times. Simulation models are the best and most practical practice tools.

[0003] Virtual reality technology uses real-life data and electronic signals generated by computer technology, combining them with various output devices to transform them into phenomena that people can feel. These phenomena can be real objects in reality or substances that are invisible to our naked eyes, and are expressed through three-dimensional models.
