Abstract
A body fluid measurement apparatus for continually monitoring the body fluids produced by a catheterized patient is disclosed. The apparatus comprises a discharge hose in fluid communication with the patient, a housing that supports the discharge hose, a dripping chamber for temporarily holding the body fluid while temperature and electrical conductivity measurements are made, a force transducer for producing a signal representing the weight of the body fluid mass collected, a container for collecting the body fluid that is suspended from the force transducer, a storage cell power source, and a computer for processing a signal generated by the force transducer, for generating a timing signal, and for computing the patient's body fluid volume flow in a certain time interval. All computed measurements are sent to a display also located on the apparatus. Additionally, two angle sensors, located in two planes orthogonal to one another, provide a signal to the computer for the compensation of the inclined position of the housing and for the compensation of an erroneous measurement of the weight of the body fluids collected. In addition, a method for the automatic monitoring and recording of the corrected volume flow of body fluids produced by a catheterized patient is also disclosed.
