An intraosseous device includes a stylet with a pointed end for penetrating bone and a cannula through which the stylet extends. The stylet has a bent portion which is engaged in a receiver in a handle cover. The cannula has an outwardly extending flare which is engaged in a corresponding seat in a hub. The handle and the hub have formations which interlock with one another when the tip of the stylet is aligned with the tip of the cannula. The interlock formations further assist torque transmission. The configuration ensures that the maximum manual torque can be applied to penetrate bone while ensuring that the stylet and cannula are aligned for maximum cutting efficiency and remain fixed to the handle and the hub respectively.

A dressing for covering a wound of a patient comprises a sheet member adapted to be adhered to the patient's skin in use to provide an airtight seal around the wound, wherein the skin-adhesion is provided by a hydrogel layeron the skin-facing face of the sheet member, wherein the sheet member defines in use a substantially enclosed spaceabove the wound, and wherein a plurality of mutually spaced-apart flutter valves formed by holesin a thin filmoverlying an upper face of a layerof the sheet member permit one-way air, blood and/or other fluid flow communication from the spaceabove the wound to the exterior of the dressing.
