Device Story

The GR100FS Urine Flowmeter is a table-top device used to measure urinary flow rates during normal micturition. It consists of a load cell that supports a collection jug, positioned under a commode chair or stand. As urine is voided into the jug, the device uses a strain-gauged load cell to weigh the fluid; the weight in grams approximates volume in milliliters. The analog signal from the load cell is digitized and processed via internal algorithms to calculate flow parameters, including total voided volume, volume at maximum flow, maximum flow rate, mean flow rate, flow time, and time of maximum flow. Results are output via a paper chart recorder. The device is intended for clinical use to assist healthcare providers in assessing patient urinary function.

Clinical Evidence

No clinical data provided; substantial equivalence is based on technological characteristics and design comparison to the predicate device.

Technological Characteristics

Table-top urine flowmeter; strain-gauged load cell sensor; digital signal processing; paper chart recorder output. Operates by weighing voided urine to derive volume and flow rate. No specific materials or software architecture standards cited.

Indications for Use

Indicated for measuring urinary flow rates in patients performing normal micturition.

Regulatory Classification

Identification

A urine flow or volume measuring system is a device that measures directly or indirectly the volume or flow of urine from a patient, either during the course of normal urination or while the patient is catheterized. The device may include a drip chamber to reduce the risk of retrograde bacterial contamination of the bladder and a transducer and electrical signal conditioning and display equipment. This generic type of device includes the electrical urinometer, mechanical urinometer, nonelectric urinometer, disposable nonelectric urine flow rate measuring device, and uroflowmeter.

Special Controls

*Classification.* (1) Class II (special controls). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to § 876.9.

Predicate Devices

• Browne Medical Systems Inc "UroFlo"

- (4) Description of the device.

Urine flowrate meter used for determining urine flow rate from patients performing normal micturition. The device functions by weighing the voided urine, the weight in grans approximates to the volume in ml the specific gravity of urine varies between 1.002 and 1.006 in infants and 1.025 in adults (95% ranges) and any inaccuracy is therefore no more than 2.5%. The urine is weighed as the urine flows using a straingauged load cell, the signal nutput from which is digitised. The flow volume is

differentiated digitally to give the flow rate, which is printed on a paper chart recorder. The flowmeter uses algorithms to calculate the following parameters.

- Total voided volume Volume at maximum flow Maximum Now rate Mcan flow rate Flow time Time of maximum flow
The recorder is a table-top device connected to the load coll which supports a jug and which fits under either a commode chair or stand.

- (5) Intended use for the device
The device is intended to be used to measure urinary flow rates

- The device has the same technolgical characteristics as the predicate device identified in (6) paragraph (3)

Re: K971913 GR100F Urine Flowmeter Dated: June 27, 1997 Received: July 1, 1997 Regulatory class: II 21 CFR §876.1800/Product code: 78 EXY & EXS

Dear Dr. Maxwell:

We have reviewed your Section 510(k) notification of intent to market the device and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations. Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (OS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under Radiation Control provisions, or other Federal laws or regulations.
