摘要：
Embodiments disclosed herein relate to detection systems for an infusion pump. An occlusion detector for an infusion pump includes a membrane that deforms in response to fluid pressure in a fluid flow path branching off of the main fluid flow path of the infusion pump. The membrane deforms in response to fluid pressure, applying an axial pressure to a piston, which in turn triggers a force sensor. A controller of the infusion pump triggers an alarm or alerts a user when a threshold is reached. A bubble detector for the infusion pump includes a light emitter and reflective surface. Light shines through the fluid flow path, refracting differently if there is air present in the flow path. A light sensor detects the light and conveys an output signal to the controller. If detected air surpasses a threshold, the controller sounds an alarm or otherwise alerts the user.本文中所揭示之具體實例係關於用於一輸注泵之偵測系統。用於一輸注泵之一阻塞偵測器包括回應於自該輸注泵之主流體流動路徑分支之一流體流動路徑中之流體壓力而變形的一隔膜。該隔膜回應於流體壓力而變形，從而將一軸向壓力施加至一活塞，該活塞又觸發一力感測器。當達到一臨界值時，該輸注泵之一控制器觸發一警報或提醒一使用者。用於該輸注泵之一氣泡偵測器包括一光發射器及反射表面。光穿透該流體流動路徑，從而在空氣存在於該流動路徑中之情況下不同地折射。一光感測器偵測該光並將一輸出信號傳達至該控制器。若經偵測空氣超過一臨界值，則該控制器發出一警報之聲音或以其他方式提醒該使用者。
