Abstract

Provided is a nerve intervention high-pressure continuous perfusion system and a use method thereof. The perfusion system comprises a fixed rack, an infusion bag conveying device, supports, an infusion bag pressing device and a monitoring and controlling system; the fixed rack is of a strip-shaped annular structure and is horizontally fixed to the ceiling and/or the wall of an operative room; the infusion bag conveying device is used for conveying infusion bags, the infusion bag pressing device is used for pressing the infusion bags and inserting and pulling out liquid inlet needles, the monitoring and controlling system is used for detecting the positions of pulleys in the infusion bag conveying device, the weights of displacement sensors and the infusion bags and the flow of liquid in the pressure bags, and meanwhile controls the work of related components of the infusion bag conveying device and the infusion bag pressing device. The nerve intervention high-pressure continuous perfusion system achieves automatic pressing of the infusion bags, detection of parameters of the infusion bags, automatic replacement of the infusion bags and alarm of abnormal infusion conditions.

Description

technical field [0001] The invention relates to the field of nerve interventional treatment devices, in particular to a high-pressure continuous perfusion system for nerve intervention and a method for using the same. Background technique [0002] During neurointerventional treatment of intracranial aneurysms and cerebrovascular malformations, continuous high-pressure perfusion is essential in order to prevent blood backflow into the coaxial catheter, resulting in thrombus formation and shedding, which in turn leads to embolism of intracranial and extracranial vessels. At present, all the options available on the market are simple manual pressurized bags. The method of use is: before the operation, put 500ml of soft-packed normal saline into a simple pressurized bag, manually pressurize to an appropriate pressure, connect the infusion set, remove air bubbles, and connect the coaxial catheter. The manual pressure bag has the characteristics of simple structure and convenient...
