Abstract: A hanger strap has a connection portion which, in use, is connected to a component, particularly part of a medical fluid administration kit, which provides a narrow-mouthed slot. An elongate strap body extends from the connection portion and has a wide portion, a narrow portion and a hanging means (usually a loop). For storage, the strap lies flat against the component. For use, the strap is bent up and its narrow portion is passed into the slot through the mouth. The strap is pulled through the slot until the wide portion is therein. This cannot escape through the mouth, and formations (e.g. ratchet teeth) resist its withdrawal.

Abstract: A vial connector has a circular array of detents that snap-engage behind the head of a vial to prevent its withdrawal. In a unitary injection molding, the detents could not lock completely or the product could not be removed from the mold. Therefore the connector employs independently displaceable detent elements (40), with independent resilient urging mechanism (42).

Abstract: A container has a body made of superimposed layers of flexible plastics film and a port sealed between said layers. The port comprises superimposed layers of flexible plastics material which provide a channel. A layer of non-sealable material is located in said channel during sealing of the port to the container body so as to prevent the opposing surfaces of the channel from being sealed together, said non-sealable layer being thereafter removed. Preferably the port comprises two layers of film united at one end thereof and along opposite sides thereof to provide the channel with a rupturable closure at the one end.

Abstract: A drug delivery system for enabling liquid in a container (10) to contact the contents of a vial (48) employs a cup (22) having a mouth through which a vial (48) is insertable head down. A conduit (70, 26, 12) extends from the cup (22) interior to the container (10) interior, possibly via a non-release coupling (16, 18, 34, 36). A retainer (50) is non-releasably engageable (64, 44) with the cup (22) to trap a vial (48) therein and urge it against the conduit (70). The retainer (50) and cup (22) may engage threadedly (62, 38), with a ratchet (64, 44) preventing disengagement.

Abstract: A clamp for closing blood vessels and the like is a tapered flat envelope of impermeable plastics film with an inlet tube at its wider end for inflating the envelope and a transverse seal limiting the inflatable region. The other end is tapered and is non-inflatable. It can be tucked under a transverse strip to secure the clamp on a blood vessel. The envelope is widened under the transverse strip and also at the transverse seal to hold the narrow end in place under the strip.

Abstract: A vascular clamp for use in surgery has a body in the form of a tapering flexible envelope, with an inlet tube at the broader end. An external strip at the broader end provides a slot through which the tail of the envelope can be threaded after passing it around the vessel. The envelope is then inflated, e.g. by a syringe, to compress the vessel. A tap closes the inlet tube after inflation, and can be operated to partially deflate the envelope and so check for leaks of blood. The disclosure also includes a method of using the vascular clamp for occluding a blood vessel.
