Disclosed herein is a blood pressure measuring device including: a pressure measuring toola fastening memberconfigured to fasten the pressure measuring toolin rest position onto a skin region covering an anastomotic region of a shunt blood vesseland a control circuitconfigured to receive an input signal from the pressure measuring tooland to process the input signal to calculate a pressure inside the anastomotic region of the shunt blood vessel

Blood pressure measuring device

A blood purification apparatus in which the pressure in a circuit is measured by directly measuring the strain of an air trap by a strain sensor without providing a pressure measuring section in the circuit.

Blood purification apparatus

A coupler joint () which includes a hollow cylindrical portion () opened at its opposite ends and a flange () disposed along the circumference of the cylindrical portion () near the longitudinal center to be interposed between a dialyzer connector () and a coupler () so as to be in liquid tight engagement; one side of the flange () of the coupler jointbeing in liquid-tight abutment with an opening () of the connector () of the dialyzer (), and the other side of the flange () being in liquid-tight abutment with the a seal surfaceof the coupler (). Accordingly, a dialysis solution does not collect in a concave groove () which accommodates an O-ring () of the coupler (), and proliferation of bacteria can be prevented.
