Problems solved by technology

When this aggregation occurs, it is difficult, if not impossible, to obtain an accurate measurement of the flow rate
For example, the initial flow of urine may be delayed by aggregation, preventing accurate measurement of the initial flow
In addition, aggregation may result in fluid clumps that form before surface tension is overcome
When the resulting amount of fluid slug is released it can cause measurement errors and may exceed the capabilities of the attached flow meter
Another potential disadvantage is that pooling can allow residual fluid to "back up" in the bladder and leave residual fluid in the drain lumen, which can lead to sanitary conditions and health problems

Embodiment Construction

[0051] The following description and drawings, which describe and illustrate certain embodiments, are arranged to demonstrate, in a non-limiting manner, reliable low-cost fluid (e.g., urine) monitoring devices and / or systems according to aspects and features of the present disclosure ( Includes several possible configurations for measuring volume and flow rate). The disclosed devices and systems may be used as urine monitoring devices / systems, or may be used to monitor other fluids in various applications. Furthermore, the present disclosure relates to ways of improving fluid flow through the system, thereby improving measurements and preventing unwanted fluid from remaining in the system.

[0052] As used herein, the term "accuracy" refers to a measure of correctness (eg, agreement) between a measurement and a true or correct value. While accuracy refers to the agreement between the measurement and the true value, it tells you nothing about the quality of the instrument bein...

Abstract

Fluid / urine monitoring devices and / or systems are provided for monitoring fluid output, including volume and flow rate. One high resolution, low cost electronic urine monitoring device and system collects urine and includes a capacitance sensor. The capacitance of the capacitance sensor may be correlated with fluid content and be used to identify urine volume and flow rate. Another high resolution, low cost flow meter is placed in line with drainage tubing and uses a capacitance sensor to measure fluid output without collecting the fluid. Other low cost urine monitoring devices use pressure based or weight based measurement sensors to measure volume and flow rate.

Description

technical field [0001] This application claims priority to US Provisional Application No. 61 / 794,917, filed March 15, 2013, which is hereby incorporated by reference in its entirety. Background technique [0002] Urinary containers or bags are often used in hospitals and healthcare facilities when it is necessary to collect urine from a catheterized patient over a period of time. These containers / bags allow the patient to remain in bed without having to be moved to use the bathroom or bedpan. The urinary system may include a catheter (eg, a Foley catheter), a collection container / bag (eg, a bag made of polymeric material or PVC film), and tubing connecting the Foley catheter to the collection container / bag. In the procedure, the patient is first catheterized and the catheter is connected to the drain container / bag by a length of tubing. Urine drains through catheters, tubing, and finally into a collection container / bag. Urine may be moved from the catheter to the collecti...
