Monitoring system for the remote supervision of a plurality of gravity perfusion sets
First Claim
1. A monitoring system for the remote supervison of gravity perfusion sets, said monitoring system comprising:
- (a) a plurality of drip perfusion sets, each perfusion set includinginjecting means for injecting by gravity a liquid into a patient,measuring means for measuring the instantaneous flowrate of the liquid injected into a patient,encoding mdoule means for periodically generating a digital identification code specific to the corresponding perfusion set and a digital signal representing the instantaneous flowrate measured by the measuring means of said perfusion set,(b) a common data bus line to which each perfusion set to be supervised is connectable through its encoding module means at any one of a plurality of different geographical locations, and(c) a remote central monitoring unit including;
data display means for displaying data pertaining to each perfusion set and data received from each perfusion set via said data bus line,decoding module means connected to said data bus line, andprocessor means operatively connected to said decoding module means and to said data display means for recognizing the identification code of each perfusion set connected to said data bus line, for converting each digital signal delivered by each perfusion set under supervison which is identified by its specific identification code to information representative of said measured instantaneous flowrate, and for displaying said information representative of the measured instantaneous flowrate in an area of said data display means allocated to each perfusion set in dependence of its identification code and independently of its geographical location along said data bus line.

Abstract
The supervision system comprises an electrical line for the transmission of digital data, at least one perfusion set including a flow meter and a module for encoding and for transmission in digital form on the line of the data concerning the instantaneous flowrate which are supplied by the flow meter, and a central unit for the processing of the said data, which central unit is connected to the said line by means of a decoding module. The central unit comprises at least one display screen, on which the quantities representing the condition of the perfusion set are displayed in analog and alphanumeric form. Application to the supervision of perfusions in a hospital environment.
