IMPROVED SEALED DEVICE FOR REGULATING THE FLOW RATE OF MEDICAL LIQUID DIRECTED TOWARDS A PATIENT

摘要

device for regulating the flow rate of the medical liquid is connected to each other, but the free part (3,4) and connected elements (6, 8) is provided including a body (2), the rotation axis (K) which serves as the part of the flow control means capable of varying the flow rate of the liquid that is directed toward the patient by rotating in the surrounding includes a plurality of recesses (25), the part (3, 4) said recess (25) due to the sealing element 10 between may optionally be connected by a communication means (30, 31), This flow rate can be adjusted accordingly. Transverse sealing means (38; 51; 57-61) are interconnected, but is provided between the free part of the second part (3, 4) (4) and the sealing element (10), the transverse sealing means ( 38, 51, 57, 61) the axis of rotation (K) in a plane perpendicular to the section for the (3,4) due to relative movement or to the arrangement between the parts or on the axis (K) (3, 4) be prevented from being discharged from the body (2) or the recess (25) of the liquid and the device (1) due to the angular arrangement of five.
