Patent JP-2003530917-A (JP)
IPC: G01F1/36
Filed: 2001-04-17
Abstract: Method and device for monitoring the flow speed of an infusion solution, such as with hemofiltration or hemodiafiltration. The device has a tube for conducting an infusion solution from a source of infusion solution to a pump device in the form of a metering pump, such as a peristaltic pump or a ceramic pump, and on to an infusion device, such as a drip chamber. The flow speed is determined by the metering pump. The flow speed is monitored separately in that the pressure across a restriction device in the tube is measured. The restriction device can be a separately arranged restriction valve. Alternatively the restriction device is arranged by the tube having a small internal diameter of the order of 0.5 mm in size. The pressure measuring device only needs to measure the absolute pressure with respect to the atmosphere. The hydrostatic pressure due to the infusion bag being hung above the pump and the pressure meter is subtracted in a calculation device.
