Abstract
A dispensing device comprises a sealed package including a collapsible compartment and an administration assembly. The administration assembly includes a delivery device in fluid communication with a substance within the sealed package. A compression panel collapses the compartment to dispense a substance through the delivery device. Embodiments for a single use dispenser for hypodermic administration of a unit dose of a therapeutic fluid, as well as therapeutic packages and methods for administering therapeutic substances to subjects, are also provided.
Core Innovation
The invention provides a device for dispensing a dose of a substance to a subject using a sealed package including a collapsible compartment containing the substance. An administration assembly is joined to the sealed package for relative movement, and a delivery device is movable from a pre-administration position to a ready position to establish fluid communication with the substance.
A reinforcement insert is joined to a wall of the collapsible compartment to provide a backing for a seal as the delivery device is advanced toward the ready position. A seal is interposed between the administration assembly and the substance to maintain the sealed package arrangement while the delivery device moves to breach the integrity of a wall or otherwise establish fluid communication.
At least one compression panel is associated with the sealed package and movable into an engaged state in which the compression panel collapses the compartment to cause the substance to be dispensed through the delivery device. The invention also provides a single use dispenser for hypodermic administration of a unit dose of a therapeutic fluid, including a hermetically sealed package having a collapsible first compartment with a first flexible wall and a rigid backing supporting the hermetically sealed package to facilitate collapsing.
The administration assembly includes an elongate needle with a piercing end for penetrating the flexible wall, and a needle actuator advances at least a portion of the needle from a pre-administration position to a ready position to cause the proximal end to breach the integrity of the flexible wall and establish fluid communication between the therapeutic substance and the delivery end.
Claims Coverage
The partial content includes two independent claims with five inventive features covering a sealed, collapsible-compartment dispensing device and a single use hypodermic dispenser. The claims also recite a reinforcement insert backing for a seal, a compression panel that collapses the compartment, a hermetically sealed collapsible compartment with rigid backing, and a needle actuator that advances a needle to establish fluid communication.
Sealed package with collapsible compartment and relative-movement administration assembly
A device for dispensing a dose of a substance to a subject includes a sealed package including a collapsible compartment containing the substance, and an administration assembly joined to the sealed package for relative movement, the administration assembly including a delivery device movable from a pre-administration position wherein the delivery device is separated from the substance, to a ready position wherein the delivery device is in fluid communication with the substance.
Reinforcement insert backing a seal during delivery-device advancement
The device includes a reinforcement insert joined to a wall of the collapsible compartment to provide a backing for a seal as the delivery device is advanced toward the ready position, wherein a seal interposed between the administration assembly and the substance is used in conjunction with advancing the delivery device.
Compression panel collapses the compartment to dispense
The device includes at least one compression panel associated with the sealed package and movable into an engaged state wherein the compression panel collapses the compartment to cause the substance to be dispensed through the delivery device.
Hermetically sealed collapsible compartment and rigid backing for needle piercing and fluid communication
A single use dispenser for hypodermic administration includes a hermetically sealed package including a collapsible first compartment containing a first therapeutic substance, the collapsible first compartment comprising a first flexible wall, and a rigid backing supporting the hermetically sealed package to facilitate collapsing of the collapsible first compartment.
Needle actuator advances needle from pre-administration to ready position to breach flexible wall
The administration assembly includes an elongate needle having a piercing end for penetrating the flexible wall of the first compartment and extending toward a delivery end for administering the therapeutic fluid to the subject, and a needle actuator for advancing at least a portion of the needle from a pre-administration position wherein the piercing end is separated from the flexible wall of the first compartment toward a ready position to cause the proximal end to breach the integrity of the flexible wall and establish fluid communication between the therapeutic substance and the delivery end.
Across the two independent claims, the core claim coverage centers on dispensing a unit dose from a sealed or hermetically sealed, collapsible compartment while an administration assembly advances a delivery device or an elongate needle from a pre-administration position to a ready position to establish fluid communication. The reinforcement insert provides backing for a seal as the delivery device advances, at least one compression panel collapses the compartment to dispense the substance, and the needle actuator-driven breach of the flexible wall establishes fluid communication for administering the therapeutic fluid.
