Description

Technical Field

[0001] The utility model relates to the field of guidewire cleaning equipment, in particular to a guidewire intervention assistant. Background Art

[0002] The guidewire, also known as the guide wire or guide line, is one of the main tools for percutaneous puncture and intubation. The guidewire guides and supports the catheter, helps the catheter enter the blood vessels and other cavities, and guides the catheter to reach the lesion smoothly. The outer layer of the guidewire is made of stainless steel wire, and the rod wire is tightly wound and can withstand repeated bending. Since the outer layer of this type of guidewire is a winding spiral structure, impurities are easily accumulated in the gaps, and it needs to be disinfected before use. The auxiliary equipment used for current guidewire interventional disinfection requires manual control to open the disinfectant supply channel. After the guidewire is extended between the disinfection rollers / brushes, the disinfectant needs to be manually supplied to the disinfection position, and the disinfectant supply channel needs to be manually closed after the disinfection is completed. It is cumbersome to use and the disinfection speed is slow, which affects the efficiency of the guidewire intervention operation. Utility Model Content

[0003] The purpose of the utility model is to provide a guidewire intervention assistant in order to solve the above-mentioned problem.
