## Abstract

Disclosed are a method, device and system for determining a flow rate of an excretion stream within an excretion collection assembly. According to some embodiments of the present invention, one of the constituent elements of the collection assembly includes a sensing module which includes an electrical and/or electromechanical component.

## Claims

### Claim 1

A system for estimating a rate of urine produced by kidneys and flowing into a bladder based on measurement of an excretion stream within an excretion collection assembly including a catheter, said system comprising:
a urinary catheter, of the excretion collection assembly, configured to be inserted into a bladder such that urine entering the bladder exits through said catheter and flows through at least part of the excretion collection assembly;
a measuring device at least a portion of which is integral with a constituent element of the excretion collection assembly, wherein said measuring device comprises:
a sensing element for sensing a rate of urine flow out of the bladder;
first circuitry connected to the sensing element to produce a signal indicative of the rate of urine flow out of the bladder, wherein said electronic circuitry includes at least one analog or at least one digital component functionally associated with said sensing element; and
second circuitry to estimate a present urine flow into the bladder based on the flow indicative signal produced by said first circuitry.

### Claim 2 (depends on 1)
