An infusion device for delivering discrete boluses of medication to a patient, using a mechanically actuated piston. The infusion pump employs a near-field communication system to convey the occurrence of an actuation, the amount of medicament remaining in the pump, and other information to a nearby near-field receiver device. The disclosed drive system and nearer-field communications system provides an infusion device capable of accurately delivering medication and providing a means for tracking and logging data while eliminating the need for a power source within the device, thereby minimizing weight and size.本發明揭示一種輸注裝置，其用於使用一機械式致動活塞對一患者輸送不連續之藥物推注劑量。輸注泵運用一近場通訊系統以將一致動的發生、該泵中剩餘的藥物量，以及其他資訊傳送至附近的近場接收器裝置。所揭示的驅動系統以及近場通訊系統使得一輸注裝置能夠準確地輸送藥物，並提供一種用於追蹤並記錄資料之方法，同時免除在該裝置內設置一電源的需要，藉以將重量及尺寸最小化。
