Device for Rendering an Injection Syringe Single-Use Only

Reference#: P01549

A single-use, self-annulling syringe is disclosed that is rendered inoperative after a single use without requiring any deliberate action on the part of the user. The injection device uses a hydrophilic expansion plug positioned in the outlet flow channel of the syringe, which expands a short time after being exposed to a drug containing water, thereby rendering the syringe inoperative.
