The measurement of residual urine volume by electrical impedance in man

DENNISTON and BAKER (1974) have reported a linear relationship between the electrical impedance at 100 kHz measured between electrodes placed close to the umbilicus and on the pubis in anaesthetised dogs and the volume of urine present in the bladder. They pointed out that this simple, non-invasive, technique for the monitoring of the urinary bladder content would be of value in post-surgical patients and in paraplegics as an index of renal function and urinary stasis. They did not, however, report any actual experience with the method in conscious

The use of a disposable waistcoat with electrodes and transducers for patient monitoring.

The use of a disposable paper laminate waistcoat is described to provide a multi-way connection to electrodes and transducers during monitoring from a patient. The waistcoat removes the strain of the multi-way cable of the monitor unit from the individual electrodes. It also conceals the electrodes and protects them from vomit.SommaireL’article décrit un gilet fait de papier de cellulose lamifié offrant de nombreuses possibilitiés de connections aux électrodes et capteurs utilisés pendant la surveillance électronique d’un patient. Le gilet supprime la tension qu’exerce le câble multi-conducteur reliant les électrodes à l’unité de surveillance. De plus, il dissimule les électrodes et les protège des vomissements.ZusammenfassungDie Anwendung eines wechselbaren Papiergürtels für Mehrwegsverbindung mit Elektroden und Transducern während der Überwachung von Patienten wird beschrieben. Durch den Hüftgürtel entfällt die Belastung des Mehrwegskabels der Überwachungseinheit von den einzelnen Elektroden. Die Elektroden sind dadurch versteckt und gegen Vomitus geschützt.
