Title:
PULSE WAVE INFORMATION MEASUREMENT METHOD FOR SIMULTANEOUSLY MEASURING PULSE PRESSURE AND BLOOD FLOW RATE AND DEVICE THEREFOR
Document Type and Number:
Japanese Patent JP3792671
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a pulse wave information measurement method for simultaneously measuring pulse pressure and blood flow rate and a device therefor.
SOLUTION: This pulse wave information measurement device capable of checking both pulse pressure and blood flow rate at the same time is provided with an insertion tube 1, a sampling tube 14, a displacement sensor 19, and a vascular diameter measurement device for measuring a blood vessel diameter and a data processor which are not shown below. The insertion tube 1 has an insertion part 11 in one end to be inserted into a human skin tissue to enter a blood vessel, and a seat body 15 in the other end. The sampling tube 14, which is inserted into a human blood vessel in one end, is provided with a blood viscosity measuring instrument 18 in the other end for measuring a blood viscosity coefficient μ by sampling the blood. A needle 191, which is provided with a displacement sensor 19 on the tip, is inserted into the skin tissue, so that the displacement sensor 19 measures a vascular displacement amount Δa.
