Load Cell Application - Medical Bag

FUTEK products are widely used in Medical Instrumentation devices and equipment to further automate and minimize human error and provide extended features for smarter interface. Some common applications are automated drug delivery or kidney dialysis system. FUTEK Model, LSB200 & LSM250 & LSM300, FBB350, FFP350 are some of the active models used in these applications.

Originally, a hanging bag that held fluid, medication, or other nutrients were infused to a patient using various clamping methods to regulate the flow. This process required continual monitoring to ensure that the solution was being delivered properly, that the bag was properly filled at all times, and that no back bleeding was occurring. Integrating a load cell and monitoring system to the basic infusion-delivery method removed guesswork from the process. The load cell measured the exact weight of the bag and immediately sent a warning to a connected device if the weight of the infusion varied from its prescribed path. Normally a small bending-beam load cell sensor with a 100-g to 1-lb capacity was placed in a cartridge under the flexible tube used to deliver the infusion. The sensor detected the changes in the tube weight during the flow and communicated with the electronic controller.
