Abstract: A system and method for a patch-like, self-contained substance infusion device (700) which can be attached to a skin surface via an adhesive contact surface. A push button (780) activation assembly can then be used to remove an interlock (730), allowing a disk or Belleville spring (735) assembly to apply an essentially even and constant pressure to the contents of a fluid reservoir assembly (710). This allows the release of one or more spring-loaded patient needles (760) into the skin surface, and establishes a fluid communication path between the patient needles (760) and the pressurized fluid reservoir contents thereby delivering an infusion into the skin. The push button (780) activation assembly further allows the release of one or more improved safety mechanisms (794) after use.

Abstract: 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.

Abstract: A single use syringe with locking needle safety cover comprising a plunger arm, plunger tip, syringe body, tip retaining sleeve, and locking needle safety cover is disclosed. The tip retaining arms grasp the plunger tip. After the plunger arm is pulled backwards, sleeve ribs of the tip retaining sleeve prevent the tip retaining sleeve from moving in a forward direction. As the plunger arm is pushed forward, the tip retaining arms are no longer surrounded by the tip retaining sleeve and the tip retaining arms move outwards and release the plunger tip. After the plunger tip has been released from the plunger arm, the plunger tip and the plunger arm cannot be reconnected and the single use syringe with locking needle safety cover cannot be reused. When rotated, the locking needle safety cover traps the injection needle thereby preventing retraction of the locking needle safety cover.
