WEARABLE, SELF-CONTAINED DRUG INFUSION DEVICE

摘要

A wearable, self-contained drug infusion device is disclosed that achieves t he precise flow rate control needed for dose critical drugs. Valve or pump structures may be used with thermal flow sensors and closed-loop control circuits for providing the desired flow rate control. The device may have a two-part construction, where the electronic components are housed in a reusable portion and the fluid delivery components are housed in a separable disposable portion. This reduces the effective cost of the device to the use r, assures sterility of the drug, and prevents fluid communication of the reusable portion by confining the fluid flow path to the disposable portion. The invention may include a wireless unit for controlling the operation of t he drug infusion device. The wireless unit may communicate with the reusable portion using radio frequency (RF) methods, optical infrared (IR) methods, o r other methods.
