摘要:
Connector assembly including a piercing member having a flow port therein attached to a first piece, with the piercing member slidingly receivable within a second piece, wherein the piercing member and the second pierce are movable relative to each other between a first position where the second pieces closes the flow port and a second position where the flow port is open. The first piece contains a locking mechanism that lockingly engages with a device when connected thereto, preventing subsequent disconnection of first piece and the device. Upon initial connection of the first piece to the device, the second piece is moved from the first position to the second position.

A device has a first part with a valve seat and storage chamber, and a second part with a flexible valve cover and actuator. The storage chamber may be formed from a pre-form blow-molded into a flexible pouch defining a variable-volume storage chamber. The flexible valve cover and valve seat form a normally closed valve seam therebetween. The valve cover is movable in response to fluid at an inlet to the seam exceeding a valve opening pressure of the one-way valve between (i) a normally closed position with valve cover and valve seat in contact with each other and defining the normally closed seam, and (ii) a second position with at least a portion of the valve cover spaced away from the valve seat to allow the fluid to pass through the seam. The one-way valve may have anti-spritz features for using the device to dispense a substance, such as to the eye. The device may contain prostaglandins without the device material absorbing the prostaglandins material and/or without the material being adsorbed into the drug.

A dispenser for dispensing a fluid includes a rigid vial that has a main fluid chamber containing a fluid, and a pump assembly that is in fluid communication with the main fluid chamber and is configured to dispense a predetermined quantity of fluid from the main fluid chamber. A flexible bladder is provided which is located within the main fluid chamber and is configured to expand to fill the ullage created within the main fluid chamber during dispensing of fluid by the pump assembly. The resilient bladder tends to force itself outwardly toward the rigid vial and, in turn, increases the pressure within the main fluid chamber in comparison to the interior of the bladder to thereby prevent the ingress of air or vapors through the bladder or otherwise into the main fluid chamber.
摘要:
A device that includes a first portion including a first polymer, a second portion including a second polymer, and a third portion defining a third polymer. The second polymer is substantially not bondable to the first polymer, and the third polymer is bondable to the first polymer and fixedly secures the first portion to the second portion. A device that includes a body and a closure and including and a first polymer, a second polymer and a third polymer, wherein the first polymer is bondable with the second polymer, and the third polymer is substantially not bondable to the first polymer.
摘要:
A device comprises a first portion including a first polymer, and a second portion that is relatively flexible in comparison to the first portion and includes a second polymer that is substantially not bondable to the first polymer. A chamber of the device is hermetically sealable with respect to ambient atmosphere and is defined by (i) an interior of the second portion, and/or (ii) a space formed between the first and second portions. A third portion of the device includes a third polymer that is bondable to the first and second polymers and fixedly secures the first and second portions to each other.
摘要:
A flexible pouch and valve assembly is provided for aseptically storing a substance, dispensing multiple portions of the stored substance therefrom, and maintaining substance remaining in the pouch in an aseptic condition sealed with respect to ambient atmosphere. The flexible pouch and valve assembly are receivable within a relatively rigid housing, and are adapted to cooperate with a pump for pumping discrete portions of substance from the pouch and through the one-way valve to dispense the substance therefrom. The assembly comprises a flexible pouch defining therein a variable-volume storage chamber sealed with respect to the ambient atmosphere for aseptically storing therein multiple portions of the substance. A one-way valve of the assembly includes a valve body defining an axially-extending valve seat and at least one flow aperture extending through the valve body and/or the valve seat.
摘要:
Device and method for needle penetrating and filling a chamber with a predetermined substance, and hermetically resealing a resulting needle hole in the device by applying radiation thereto. The needle penetrable and resealable portion defines a predetermined wall thickness in an axial direction thereof, and may include a thermoplastic that substantially prevents the formation of particles released into the chamber from the needle penetrable and resealable portion during penetration by and withdrawal of the needle. Such thermoplastic may include a predetermined amount of pigment that allows the thermoplastic to substantially absorb laser radiation at a predetermined wavelength, substantially prevent the passage of radiation through the predetermined wall thickness thereof, and hermetically seal a needle aperture formed in the needle penetration region thereof in a predetermined time period.

摘要:
A container including a body defining an outflow opening and at least one chamber adapted for storing a product, such as a fat containing liquid product, and a container closure including a primary seal for hermetically sealing the product within the chamber during storage. The container closure includes a sealing member forming a substantially fluid-tight seal between the container closure and the body, and a dispensing member in fluid communication with the chamber. The container closure and body move relative to each other between a first position where the primary seal is seated about the outflow port to hermetically seal the product in the chamber during storage, and a second position where the primary seal is displaced from the outflow port to allow product to pass from the chamber through the outflow port and into dispensing member to dispense the product.
摘要:
A multiple dose syringe has a first valve defining a first valve opening pressure and a second valve defining a second valve opening pressure. A storage chamber in fluid communication with the second valve stores multiple doses of a substance therein and includes an outlet for dispensing multiple doses of the stored substance therethrough. A compression surface is movable between first and second positions and defines a compression chamber between the compression surface and the first valve. Movement of the compression surface in a direction from the first position toward the second position dispenses substance in the compression chamber through the first valve and out of the syringe. Movement of the compression surface in a direction from the second position toward the first position causes substance to flow from the storage chamber through the second valve and into the compression chamber.
