20150157359 | PUNCTURE NEEDLE - The success rate of the insertion of a dull needle into a puncture hole is improved. A puncture needle is provided which is inserted into a puncture route that is formed to cover from a skin surface to a shunt vessel surface so as to expand an incision of a puncture hole formed in the shunt vessel surface. The puncture needle has an inclined end face that is inclined toward a front end of the needle, and a front end part of the inclined end face has an edge having no sharpness. Right and left side parts of the inclined end face which are contiguous with the front end part are respectively inclined outward, and side edges of the side parts are provided with cutting lines. | 06-11-2015 |
20130158461 | HEMODIALYSIS SYSTEM - A hemodialysis system includes a body fluid volume calculating unit, a dialysis condition input unit with which blood flow velocity and dialysis fluid flow velocity in hemodialysis treatment performed after specific hemodialysis treatment can be input and input values of the blood flow velocity and the dialysis fluid flow velocity can be adjusted, a dialysis dose calculating unit configured to calculate, when the blood flow velocity and the dialysis fluid flow velocity are input to the dialysis condition input unit, by analyzing a mathematical model concerning urea kinetics, a dialysis dose of the hemodialysis treatment from the input blood flow velocity and the input dialysis fluid flow velocity, a body fluid volume calculated by the body fluid volume calculating unit, and the like, and a dialysis dose display unit configured to display the hemodialysis dose calculated by the dialysis dose calculating unit. | 06-20-2013 |
20110295152 | PUNCTURE METHOD, INCISION NEEDLE, PUNCTURE NEEDLE, NEEDLE CAP AND INSTRUMENT FOR BLOOD PURIFICATION TREATMENT - The present invention is a method of puncturing a shunt blood vessel, using a incision needle having a pointed extremity that protrudes apically from a hypothetical angled plane formed by cutting straight through the tip of the needle at an angle, wherein the pointed extremity of the incision needle is inserted into a shunt blood vessel, thereby forming a reverse U-shaped incision on the surface of the shunt blood vessel, with the apex of the incision being on the bottom side in the direction of insertion. | 12-01-2011 |
20110125033 | BLOOD PRESSURE ESTIMATION APPARATUS AND BLOOD PRESSURE ESTIMATION METHOD - [Problem to be Solved] To provide a non-invasive blood pressure estimation apparatus which can accurately estimate systolic blood pressure from blood flow sound of a dialysis patient and can continuously estimate systolic blood pressure by continuously picking up the blood flow sound of the subject. | 05-26-2011 |
