Abstract
A hard package assembly is disclosed having a cam mechanism for ejecting a syringe from a hard package container with the use of a single hand. The cam mechanism including a push button and a button retainer, the push button having a trapezoidal body having a button face, a distal face adjacent and distal to the button face and a sloped face opposite the button face, the button retainer having a proximal portion, a distal portion in contact with the sloped face of the push button and a distal hook in contact with a bottom surface of the barrel flange. A method of use and a method of assembly are also disclosed.
Claims25
A single-hand operable assembly comprising:
- a hard package container comprising a main compartment and an ejection compartment, the ejection compartment having a rectangular cross-sectional shape with an opening having a distal edge positioned on a short face of the rectangular shape of the ejection compartment, the ejection compartment having an inside surface, an open end at a right angle and proximal to the short face and a bottom surface at a right angle and distal to the short face;
- a syringe having a plunger rod and a barrel positioned at least partially within the main compartment, the plunger rod having a proximal end, the barrel having a barrel flange, the barrel flange having a bottom surface;
- a cam mechanism comprising a push button and a button retainer, the push button having a trapezoidal body having a button face, a distal face adjacent and distal to the button face and a sloped face opposite the button face, the button retainer having a proximal portion, a distal portion in contact with the sloped face of the push button and a distal hook in contact with a bottom surface of the barrel flange;
- and,
- a seal covering the open end and the button face.
A method of use of a hard package assembly with one-handed operation comprising the steps of:
- depressing a button face of a push button by a finger of a practitioner, the push button positioned within an ejection compartment of a hard package container;
- pivoting a distal portion of a button retainer relative to a proximal portion of the button retainer such that a distal hook of the button retainer translates in a medial and proximal direction;
- advancing a barrel flange of a barrel of a syringe positioned within a main compartment of the hard package container by translation of the distal hook against a bottom surface of the barrel flange;
- advancing a plunger rod of the syringe in a proximal direction such that a proximal end of plunger rod pierces a seal, the seal covering an open end of the ejection compartment;
- and,
- withdrawing the syringe from the hard package container.
A method of assembly of a hard package assembly with one-handed operation comprising the steps of:
- positioning a button retainer within an ejection compartment of a hard package container with guide tabs of the button retainer interdigitated with a retainer guide path of an inside surface of the ejection compartment;
- positioning a push button within the ejection compartment with a button face flush with an opening of the ejection compartment, and a sloped face of the push button abutting against a distal portion of the button retainer;
- positioning a barrel of a syringe having a plunger rod within a main compartment of the hard package container such that a bottom surface of a barrel flange is in contact with a distal hook of the button retainer;
- positioning a cutter over a proximal end of the plunger rod such that the cutter does not protrude beyond the open end of the ejection compartment;
- and,
- covering the opening of the open end with a seal.
