Abstract
A cap assembly includes an access member including a first section and a second section. The first section includes a connection portion that is attachable to an extraction device that extracts contents of a reservoir. The connection portion includes a first opening. The second section includes a second opening in fluid communication with the contents of the reservoir when the access member is secured to the reservoir. The cap assembly includes a valve member insertable into the access member so as to be in fluid communication with the first opening and the second opening and such that the valve member i) seals the contents of the reservoir at the first opening when the connection portion is not attached the extraction device, and ii) provides access to the contents of the reservoir through the first opening when the connection portion is attached to the extraction device.
Core Innovation
The invention relates to needleless extraction and needleless administration using a cap assembly for a medical vial. The cap assembly includes an access member with a first section and a second section, where the first section includes a connection portion attachable to an extraction device that extracts contents of a reservoir. The connection portion includes a first opening, and the second section includes a second opening in fluid communication with the reservoir contents when the access member is secured to the reservoir.
A valve member is insertable into the access member so that it is in fluid communication with the first and second openings. The valve member seals the contents of the reservoir at the first opening when the connection portion is not attached to the extraction device, and the valve member provides access to the reservoir contents through the first opening when the connection portion is attached to the extraction device. The valve member extends from the connection portion of the access member to the second opening when the valve member is inserted.
The cap assembly further includes a sealing member and a housing separate from the reservoir. The housing is configured to secure the access member and the sealing member to the reservoir such that the sealing member is between the reservoir and the access member. The disclosed structures include a flexible/compressible valve member with a slit for sealing and opening behavior, a flexible sealing material such as silicone/rubber, an access member formed from polymer/plastic, and a metal bendable or crimped housing that secures components to the reservoir.
Claims Coverage
The independent claims cover a cap assembly, a vial assembly including the cap assembly, and a package that further includes an extraction device. Across these independent claims, the inventive features are centered on an access member with first and second openings, an insertable valve member that seals when not attached and provides access when attached, and a separate housing that secures the access member with a sealing member between the reservoir and access member. In addition, the valve member extends from the connection portion to the second opening when inserted.
Access member with first and second openings and attachable connection portion
An access member including a first section and a second section, the first section including a connection portion that is attachable to an extraction device that extracts contents of a reservoir, the connection portion including a first opening, the second section including a second opening in fluid communication with the contents of the reservoir when the access member is secured to the reservoir.
Insertable valve member providing conditional sealing and access
A valve member insertable into the access member so as to be in fluid communication with the first opening and the second opening and such that the valve member seals the contents of the reservoir at the first opening when the connection portion is not attached to the extraction device, and provides access to the contents of the reservoir through the first opening when the connection portion is attached to the extraction device.
Sealing member between reservoir and access member and separate housing
A sealing member and a housing separate from the reservoir and configured to secure the access member and the sealing member to the reservoir such that the sealing member is between the reservoir and the access member.
Valve member extends from connection portion to second opening when inserted
When the valve member is inserted into the access member, the valve member extends from the connection portion of the access member to the second opening of the access member.
Package with reservoir and extraction device including fixable cap assembly
A reservoir to hold contents, an extraction device to extract the contents, and a cap assembly fixable to the reservoir, the cap assembly including an access member, a valve member, a sealing member, and a housing separate from the reservoir configured to secure the access member and the sealing member to the reservoir such that the sealing member is between the reservoir and the access member.
The independent claim set is directed to a cap assembly, and corresponding vial assembly and package, that uses an access member defining a first opening and a second opening, an insertable valve member that seals at the first opening when the connection portion is not attached to an extraction device and provides access through the first opening when attached, and a separate housing with a sealing member positioned between the reservoir and the access member; the valve member extends from the connection portion to the second opening when inserted.
