Abstract

1,116,997. Measuring blood pressure; transfusion apparatus. CANADAIR Ltd. 12 July, 1966 [27 Aug., 1965], No. 31306/66. Headings A5K and A5R. Apparatus for indicating variations of blood pressure during the infusion into a vein of a saline solution 5 comprises a reservoir 3 connected by a conduit 7 and narrow bore tubing 11, 15 to an injection needle 17 and also connected through a T-junction 13 to a transducer 33, 71 which provides an electrical signal to an instrument 75 in dependance of the pressure in the infusion solution. The transducer comprises a part 33 (see also Figure 5, not shown) containing a flexible diaphragm (41) transmitting the pressure variations via a second fluid (distilled water) to a diaphragm in a part 71, this second diaphragm varying the value of a resistor in a bridge circuit also contained in the part 71. A control unit 73 provides electrical power to the bridge circuit and enables the bridge to be balanced at any desired reference level. The control unit also includes resistors (A,B,C) used in the calibration of the apparatus and it is stated that by stopping the flow of saline solution for a short duration the actual blood pressure may be measured.
