Abstract: The invention relates to a resealable port (2), or an injection site (24), for use with a syringe cone (16), the port being formed with a housing including a conduit (1) sealed by a resealable diaphragm (7) wherein a sealing annulus (6) is juxtaposed to, and interacts with, the diaphragm (7) to form an annulus and diaphragm assembly whereby the arrangement of the housing and the assembly is such that action of the syringe cone (16) as it passes through the diaphragm generates a cantilever action about a point (12) which serves to seal the diaphragm and the annulus in the housing.

Abstract: The present invention provides an assembly of an intravenous cannula insertion device and an elongate needle protector, said protector comprising a slotted tube, a needle and needle hub, said needle hub comprising a protrusion extending through said slot to allow the needle and needle hub assembly to be slidable within said protector,a cannula hub operatively inter-engagable with said needle hub within said protector, whereby said needle hub and said cannula hub are extensible together from the protector to allow i.v. insertion of the cannula, and wherein said assembly includes retraction prevention latches for preventing retraction of the cannula hub after it has been fully extended;and wherein the cannula hub remains interlocked with the needle hub when fully extended until released from the assembly by a fin, so that needlestick is prevented.

Abstract: The invention provides an intravascular placement apparatus adapted for operative association with an introducer needle. The apparatus provides a cannula having a connector hub at its remote end, a self-sealing septum disposed across the internal lumen of the cannula whereby the cannula can be positioned by co-operation with the introducer needle, and a blunt hollow adaptor adapted to penetrate a channel in the septum. According to the invention, the self-sealing septum is formed from a resilient material which ages rapidly after forming to a point where its resilience is not significantly further affected by time. Preferably the channel is formed in situ in the septum when the septum has aged for a predetermined period.

Abstract: The invention provides an assembly of a protective shield for a needle channel and a self-sealing diaphragm, wherein the protective shield is generally cup-shaped and is provided with an aperture, said self-sealing diaphragm being retained in the aperture, the arrangement being such as to protect the fingers of the operative from needle-stick by the miss-direction of a hypodermic needle. The diameter of the aperture may approximate to, or be smaller than, the internal diameter of the inlet of the needle channel so that only is needle-stick obviated, but also the tendency of the needle point to tear the seal-sealing diaphragm is significantly reduced.

Abstract: The invention provides an assembly of a catheter and a cannula for cooperation therewith, wherein the catheter is provided with visible gradations disposed on the surface of the catheter adjacent its hub. The catheter cooperates with the cannula which is provided with gradations adjacent its distal tip. The arrangement in accordance with this invention allows for the accurate placement of small biological particles such as human embryos to appropriate body cavities.

Abstract: A catheter with liquid flow control means having a hub portion and a bore therethrough, where the hub portion is resiliently distortable to close the bore by manual pressure prior to connection of the hub portion to other apparatus, but closure of the bore by manual pressure is prevented after the connection has been made.

Abstract: A sterilizable package for medical or surgical instruments or the like, said package consisting essentially of a rigid or semi-rigid container including a filter element made of porous plastic and adapted to allow the passage of a sterilizing gas therethrough, but prevent the entry of bacteria into the package.
