Insulin Pump

Overview

Description

Insulin administration is vital for diabetic patients to regulate blood glucose levels and prevent complications from irregular blood sugar levels. Insulin pumps are wearable medical devices that automatically inject insulin by mimicking the body's natural insulin release. They provide a steady basal insulin flow throughout the day and night, along with additional bolus doses at mealtimes to regulate blood sugar spikes. This device eliminates the need for manual insulin injections, offering improved insulin therapy and peace of mind for the patient.

This insulin pump design interfaces with a continuous glucose monitor (CGM) to track blood glucose levels and administer insulin appropriately, offering accurate insulin delivery with connectivity features.

System Benefits:

  • Precise motor control ensures accurate insulin delivery.
  • The closed loop system with a CGM sensor automates insulin dosage.
  • Information is displayed on both a local OLED screen and a smartphone app to provide data on insulin delivery.
  • NFC technology enables secure communication between the sensor and the pump.
  • Fast, safe charging via a magnetically connected USB cable minimizes injury risks.
  • PC connectivity via USB interface enhances data management.
  • Bluetooth® Low Energy (LE) 5 facilitates secure communication with the CGM sensor.
  • Low sleep current extends battery life for uninterrupted usage.
