Patient Controlled Analgesia Device which allows emergency patients to titrate their own pain medications safely and with minimal supervision.
Our group has designed and patented an inexpensive patient controlled analgesia device (PCA) which allows emergency patients to titrate their own pain medications safely and with minimal supervision. Unlike standard electronic PCAs it is easy to set up, purely mechanical and designed to be disposable. The device consists of a syringe, a spring and restrictor, plunger, medication reservoir, and two one way valves in a sealable box. The nurse or pharmacist fills the reservoir with medication and seals the box. The device is connected to the patient’s intravenous line. The patient pushes the plunger and injects a small dose of medication when they need pain relief. Then the spring and restrictor slowly refill the syringe. The design ensures that the patient cannot give more medication than is prescribed or give it too fast.
The believe the device will increase patient safety, improve patient satisfaction, reduce nursing and physician workload, reduce the risk of drug diversion and decrease overall hospital costs for many of the 130 million ER visits each year.
