Intelligent puncture system for indwelling needles

Abstract

The application relates to the field of blood sampling equipment, in particular to an intelligent puncture system for a retention needle, which comprises a limiting module, a blood vessel positioning module, a control module and an illumination module; the limiting module limits the body position of a patient's arm for retention needle puncture and sends a positioning signal to the control module after completing the body position limitation; the illumination module irradiates a puncture area according to a starting signal of the control module; the blood vessel positioning module detects blood vessel position information in the puncture area according to the starting signal of the control module; the control module sends the starting signal to the illumination module and the blood vessel positioning module according to the positioning signal obtained from the limiting module, judges the accuracy probability of the blood vessel position according to the obtained blood vessel position information, and judges to perform the retention needle puncture when the accuracy probability is greater than a threshold value. The application improves the accuracy of blood vessel position determination during the retention needle puncture.
