摘要:
A haemodialysis machine (1) provided with a measurement system (100)(200) for measuring the flowrate configured so as to: supply a heat-resistive component (12) arranged in a duct, with an electric current (Is(t)) having an alternation of first (ISL) and second (ISH) pre-set current values, determine at least a first resistive value (RL) and a second resistive value (RH) indicative of a resistance variation on the heat-resistive component caused by the alternation of the first (ISL) and second (ISH) current values, determine a differential resistive value (Rd) based on the difference between the first and second resistive values (RH)(RL) and determine the flowrate of the liquid (Q) in the duct based on the differential resistive value(Rd).
摘要:
A differential flow-meter (10*, 1000) for measuring the weight loss in dialysis treatments. The differential flow- meter (10*, 1000) is of the "thermal anemometer" type.

. Portable device (1) for diagnosis of gastro-esophageal reflux disease of a patient (2) provided with a monitoring unit (7) comprising at least one probe (9); the probe (9) is aimed at monitoring the flow of material through the lower esophageal sphincter (10) of the patient (2) for a predetermined number of hours no lower than twenty-four; a portable data storage unit (8), which is connected to the monitoring unit (7) for collection of the data detected by said monitoring unit (7); wherein the probe (9) is an ultrasound probe which is applied externally to the patient (2) in the vicinity of the lower esophageal sphincter (10) of the patient (2).
