FIELD: medical equipment.SUBSTANCE: invention relates to a device for supplying and metering a fluid for medicinal purposes, comprising at least one pump for conveying fluid and at least one component (10; 40) through which fluid is conveyed. Component (10; 40) has at least one recess (11), which is tightly covered by sensor component (20) that is made of a pressure-sensitive material, wherein material of component (10; 40) is harder than that of sensor component (20). Device also includes force sensor (30), which can be used to measure pressure-induced changes of sensor component (20) in area of recess (11). Force sensor (30) comprises a plunger, which directly contacts in area of recess (11) with surface of sensor component (20).EFFECT: providing compact design and easy maintenance.17 cl, 7 dwg |
