Syringe safety assembly

摘要

Systems, devices, and methods are provided for providing safe syringe assemblies for injections. The syringe assemblies include a shielding mechanism that covers a syringe needle after an injection is delivered, thereby reducing the risk of a subsequent accidental stab from the needle. The shielding mechanism has a pre-injection configuration in which the needle extends beyond the housing and a post-injection configuration in which at least one component of the syringe assembly covers the needle. In some implementations, the syringe assembly includes a lock that inhibits the assembly from returning to the pre-injection configuration once an injection is delivered. The syringe assemblies may also include a bevel orientation mechanism that allows a user to align a needle bevel to accurately insert a needle for injection.

主权项

1. A syringe assembly including a bevel orientation mechanism, said assembly comprising:
a housing having an inner chamber with a first opening for receiving a syringe and a second opening to allow a needle of the syringe to extend beyond the housing; a collar coupled to the second opening of the housing; and a first sheath disposed within the collar and the housing, wherein rotation of the collar relative to the housing drives rotation of a syringe inserted into the syringe assembly.
