Abstract
The present disclosure describes a syringe assembly including a syringe including a Luer connection and a tip, a plunger, a tip cap, a tamper evident cap disposed over the tip cap, and a film including a frangible connection. The film secures the tamper evident cap to the Luer connection, where the frangible connection can break under a force applied to the tamper evident cap such that the tamper evident cap disengages from the Luer connection when the frangible connection breaks.
Claims25
A syringe assembly, comprising:
- a syringe having a barrel body that extends from a proximal end to a distal end and defines a chamber extending along an axial direction therethrough, a luer connection at the distal end, and a tip extending from the distal end along the axial direction and defining an outlet in fluid communication with the chamber, wherein the chamber contains a material;
- a plunger received within the chamber of the syringe to create a fluid seal within the barrel body;
- a tip cap defining a central passage configured to receive a portion of the tip such that the tip cap creates a fluid seal over the outlet;
- a tamper evident assembly, comprising:
- a tamper evident cap disposed over the tip cap, wherein the tamper evident cap has a main body that defines a proximal end defining an opening, a closed distal end opposite the proximal end along the axial direction, an outer surface, and an inner surface opposite the outer surface that defines a passage extending from the opening of the proximal end configured to receive the tip cap;
- and
- a film including a frangible connection and configured to secure the tamper evident cap to the luer connection,
- wherein the frangible connection is configured to break under a force applied to the tamper evident cap such that the tamper evident cap is configured to disengage from the luer connection when the frangible connection breaks.
A method of filling a syringe with a material, the method comprising:
- receiving a syringe having a barrel body extending from a distal end having a luer connection and a tip, wherein the tip defines an outlet having a tip cap placed thereon, to an open proximal end, the barrel body defining a chamber that extends along an axial direction therethrough;
- filling the chamber with the material through the open proximal end;
- placing a plunger at the open proximal end of the chamber;
- placing, after placing the plunger at the open proximal end of the chamber, a tamper evident cap over the tip cap;
- and
- attaching a film to the tamper evident cap and the luer connection such that the film secures the tamper evident cap to the luer connection.
A tamper evident assembly, comprising:
- a tamper evident cap having a main body that defines a proximal end defining an opening, a closed distal end opposite the proximal end along an axial direction, an outer surface, and an inner surface opposite the outer surface that defines a passage extending from the opening of the proximal end configured to receive a tip cap and a luer connection of a syringe;
- and
- a film including a frangible connection and configured to secure the tamper evident cap to the luer connection, wherein the frangible connection is configured to break under a force applied to the tamper evident cap such that the tamper evident cap is configured to disengage from the luer connection when the frangible connection breaks.
