Patient - controlled analgesia (PCA) allows patients that suffer from chronic or postoperative pain to increase an continuous intravenous infusion rate of an analgesic in case of entrance of acute pain for a defined amount of time.
Current PCA-pumps are too big to be worn on the body without a massive disturbance of movement. Through the use of a micromembrane pump with high precise flow rates the mounting dimensions could be minimized while the medicaments concentration could be increased enough to take only about a twentieth part of the usual volume.
The system is controlled by a wireless remote, that is connected with the pump device via Bluetooth Low Energy. Here the patient gets informed about the current state of his therapy and alert.
