Abstract:
A low-flow metering device 10 for measuring the flow of an amount of liquid exceeding 0.05 ml., in which a first chamber 12 has an inlet 14, and an outlet 16 in fluid communication with a second chamber 17, the first chamber 12 containing an element 22 creating a laminar flow 24. The outlet 16 of the first chamber is provided with a drop generator 19 leading to the second chamber 17 and is sized to release a series of droplets 18, each of the droplets forming and breaking away under its own weight from liquid in the drop generator orifice. An overflow conduit 21 extends between an upper area of the first chamber 12 and a lower area of the second chamber 17 for equalizing gas pressure between the two chambers 12, 17. An electronic system 28 is positioned in the second chamber 17 below the drop generator 19 for counting the passage of each droplet 18 exiting therefrom, and an information processing unit 32 is connected to the electronic system 28 for receiving and recording information.
Abstract:
An electronic liquid flow measuring system has a power source, a main electronic flow meter and a secondary liquid low flow electronic meter connected to bypass the main meter. A microprocessor controls flow measurements and a three-position valve is connected to both meters for closing the main flow meter at very low flows to permit only the secondary liquid flowmeter to operate at such low flows. At normal flows, the valve is in a position to allow liquid to flow through both meters and when liquid flow exceeds a predetermined flow rate, the valve blocks all flow.
Abstract:
A diagnostic method and apparatus for detecting at least one change in a urinary parameter indicative of a body malfunction, the method comprising at least semi-continuously monitoring in real time at least one of a sodium level, an oxygen level, a potassium level, and combinations thereof in the urine of a catheterized patient; whereby at least one parameter is monitored so as to detect one or more changes in the at least one parameter to reflect at least one of a fluid state, an electrolyte balance, a kidney state, a kidney perfusion and an organ perfusion in the patient, indicative of the body malfunction in the patient, in which the monitoring is preferably performed through electrodes that are arranged perpendicularly to the flow of urine through a patient's catheter system.
