摘要:
A hollow needle comprising a shaft having a distal portion suitable for passing through an elastomer closure of a container, said shaft extending in a longitudinal direction and having a central longitudinal axis, and having an internal longitudinal conduit therein for the flow of liquid and one or more orifices communicating between the conduit and the exterior of the needle, the distal portion of the shaft being provided with a pointed end that has a profile comprising a cutting edge in the form of two part cutting edges converging in the longitudinal direction to meet at the needle point, each part cutting edge extending in a straight line in a widthways direction across a plane including the central longitudinal axis, on both widthways sides of the cutting edge the pointed end having a profile which is a non-cutting surface, wherein the pointed end of the needle tapers from an outer surface of said distal portion toward the point of the needle, and the distance, measured in a further plane defined by said two part cutting edges between the outermost ends of said part cutting edges, is smaller than the largest outer dimension of said distal portion, measured perpendicular to said central axis in said further plane.
摘要:
A novel elastomer material having an absorption coefficient for laser light of 0.5-2.5 mm−1, preferably being a base thermoplastic elastomer compounded with a colorant which comprises a Pantone 4597C pigment mixed with a carrier material. The elastomer is suited for use as a pharmaceutical vial closure which can be punctured by a filling needle and the puncture hole heat sealed by a focused laser.
摘要:
A process for preparing a lyophilized material, providing a container having a penetrable envelope and containing the material in a carrier liquid, whereby the penetrable region is penetrated with a penetrator which provides a conduit through the envelope, and the carrier liquid id evaporated out of the container via the conduit, after which the penetrator is withdrawn. Apparatus suitable for performing the process is also disclosed.
摘要:
An apparatus for shell freezing a liquid content in a container, comprising an endless loop conveyor having a conveying length adapted to convey plural containers such as pharmaceutical vials, incorporating plural rollers to spin the containers as they are conveyed by the conveyor, and a return length, along at least part of the return length the rollers are immersed in a cooling liquid at a temperature below the freezing point of the liquid content of the containers, and along the conveying length the rollers are entirely above the surface of the cooling liquid. A preferred cooling liquid is liquid nitrogen, the evaporating vapour of which can be used to shield vials on the conveying length.
摘要:
Apparatus for introducing a medicament into containers, especially vials, in which the containers are passed through an enclosure and exposed therein to a sterilising electron beam. The containers are then conveyed to a filling station situated outside the enclosure at which a wall part of the container is punctured with a filling needle and medicament introduced into the container via the needle then withdrawing the needle. Preferred apparatus also includes means for heat sealing the puncture site. A corresponding process is disclosed.
摘要:
A closure system for a pharmaceutical vial, comprising an elastomer closure part, a clamp part which holds the closure part in engagement with the mouth of the vial, and a cover part which engages with the clamp part. The interior of the closure part is profiled to minimize retention of residual liquid therein.
摘要:
A closure system for a vial comprising: an elastic closure part to engage the mouth opening, a clamp part to hold the closure part in a closing relationship with the mouth opening, the clamp part defining an upper aperture through which a region of the upper surface of the closure part is exposed when the clamp part is engaged with the vial, a cover part to engage the clamp part to cover the exposed region, the cover part engaging with the closure part to provide two or more concentric ring-shaped seals, at least part of the cover part being removable from the vial to allow access to the closure.
摘要:
A system for making a connection between the interior and exterior of a compartment, comprising a door opening through the compartment wall, a connector body which can engage with the wall, and having a connection port through it, and a removable cover on the connector body. The body is engaged with the door opening, and an inner door within the compartment engages and removes the cover. A preferred construction creates a single line of confidence seal. The system is particularly suited for sterile compartments.
摘要:
A connector for forming a sterile connection between two tubes, comprising first and second parts which comprise connectable conduits and which can mate, first and second covers which can be removed from the so-mated parts to expose connectable ends of the first and second conduits, so that the conduits can then be connected.
