Title:
PUNCTURE DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/085430
Kind Code:
A1
Abstract:
Provided is a puncture device that can easily check whether a target site is a vein or not. The puncture device 10 comprises a needle part 12 that can puncture into a blood vessel and a vibration detection part 14 that detects vibrations of the needle part 12. The needle part 12 can be used to puncture a blood vessel and insert an insertion into the vessel through the internal cavity of the needle part 12. By focusing on the difference in vibrations between arteries and veins, upon puncturing, a user can grasp the vibration state applied to the needle part 12 and differentiate whether the site in contact with the needle part 12 is a vein or an artery and, after confirming that the target site is a vein, the user can puncture the vein. This approach enables puncture with enhanced safety.
