Tom Road Bishop, California 93514 # 510(k) Summary of Safety and Effectiveness # Identification of the Device | Proprietary-Trade Name: | MT Alert Infusion Monitor | |-------------------------|-----------------------------------------------------| | Classification Name: | Monitor, Electric for Gravity Flow Infusion Systems | | Device Class: | II | | Product Code: | FLN | | Common/Generic Name: | Gravity Infusion Monitor | #### Equivalent Predicate Devices The MT Alert Infusion Monitor is substantially equivalent in design and function to the Smith & Nephew Dyonics LeveLert System. ### Indications for Use MT Alert Infusion Monitor is intended for use in any healthcare setting where gravityflow infusions are utilized. ## Description of the Device The MT Alert Infusion Monitor is a passive weighing device that alarms when the infusion bag is near-empty. The alarm point can be set by the user. In addition, MT Alert may also assist in monitoring fluid bolus administration. MT Alert will alarm when a prescribed bolus of fluid has been taken from the infusion bag. MT Alert provides various audio and visual alarms. MT Alert operates from common alkaline batteries and mounts on common poles and rods. ## Safety and Effectiveness in Comparison to Predicate Devices. The validation procedures performed on the system indicate that the new device is as safe and effective as the predicate devices. {1}------------------------------------------------ 4p page 1 of 2 # Substantial Equivalence Chart | Feature | MT Alert™ | LeveLert | |--------------------------------------------------------------------------------------------------------|-------------------------------------------------------|--------------------------| | Used for monitoring the fluid level of an infusion bag. | Yes | Yes | | Automatic alarm when the fluid level has reached a pre-determined weight with audio and visual alarms. | Yes | Yes | | Adjustable near-empty alarm point. | Yes- Easily programmed by hanging the desired weight. | Yes. | | Accommodates most typical infusion bag sizes. | Yes (up to 3 liter size) | Yes (up to 3 liter size) | | Bolus monitoring feature. | Yes (1 liter mode only) | No. | | Passive device, no fluid control functions. | Yes | Yes | | Infusion Container hangar. | Yes | Yes, | | Pole Mounting. | Yes | Yes | | Power | 2- AA batteries, typical 180 day life | Powered externally | | Device Class. | Class II | Class II | Darling Castaneda MB Richard Citrenbaum, MD, President (9) (3 / ス / ス / ス / ス / (Premarket Notification [510(k)] Number) {2}------------------------------------------------ Image /page/2/Picture/1 description: The image is a black and white logo for the Department of Health & Human Services USA.
