Abstract
A single-use medical syringe has a syringe lock that prevents repeated syringe aspiration and dispensing of fluids to patients. A pivoting syringe lock is coupled to the proximal open end of the syringe barrel. The syringe lock has or more cantilever lock forks in continuous, biased, sliding, abutting contact with the plunger. Each lock fork engages a corresponding plunger detent oriented on a proximal end of the syringe plunger, after the plunger is fully advanced within the syringe barrel. The plunger remains locked in an advanced position within the syringe barrel while each lock fork is engaged in its corresponding plunger detent. In some embodiments, a removeable plunger clip is coupled to the syringe to prevent inadvertent advancement of the plunger into the syringe barrel and premature locking of the syringe prior to administration of medication to a patient.
