Exempt from puncture needle to the hurt of artery and vitals.But in puncture process, puncture needle will receive very big frictional force and cut
Cut power.Especially in the first stage of puncture, puncture needle needs to pierce through tissue surface biomembrane, is pierced into syringe needle directly in soft tissue
Portion, puncture needle will receive the viscoelastic property of very big frictional force and skin soft tissue, prevent puncture needle from being easily pierced into skin
Inside skin tissue.
Domestic Research Team, Dalian University of Technology has recorded the entire mistake that mosquito is sucked blood in the case where high-speed motion picture camera records shooting
Journey has extensively studied the vibration puncture properties of mosquito lancet.After analysis is it is found that lancet syringe needle penetrates skin surface, mosquito meeting
Start vibration with serrate lower jaw and continues to puncture deep skin.Vibration significantly reduces lancet and is puncturing cutting soft tissue
Puncture force and frictional force in the process.The present apparatus attempts to change puncture technique in terms of reducing resistance when puncturing pin puncture
Into.
