Monitor sheath

An optical switch () includes a light input (), a plurality of light outputs () and at least one light pathway movable from a first position where a light communication path is formed between a light input () and a first light output () and a second position where a light communication path is formed between the light input and a plurality of light outputs. Multiple light pathways are configured within the switch and selectable by rotation of a switch housing part enabling sequential selection of light communication paths. The switch can be used on a surgical device to control illumination of the surgical field during a procedure.

Surgical retractor

Surgical instrument

A fluid handling device comprises a barrel for containing fluid to be delivered through a needle, a needle-mounting hub at one end of the barrel, a biasing element arranged to urge the hub inwardly of the barrel, a stop element blocking inward movement of the hub into the barrel, and a hollow plunger which is movable within the barrel to deliver fluid from the barrel via the needle and has at its forward end a portion which is severable in response to movement of the plunger over the final part of, or at the conclusion of, its delivery stroke to allow retraction of the needle-mounting hub into the hollow plunger, the hub and the stop element being formed as plastics mouldings in such a way that the stop element is axially captive with the hub and the plunger being arranged to disengage the stop element and the hub during said final part of, or at the conclusion of, the delivery stroke to allow the biasing element to drive the needle into the hollow plunger.

Retractable needle syringe

A sheath for sheathing the needle of a hypodermic syringe and penetrating the rubber cap of a vial or the like, the sheath having apertures therein to allow the ingress of liquid into a zone thereof with which the needle communicates so that the liquid drawn through the needle during filling of the syringe first enters that zone before entering the needle. The sheath is further provided with a filter element and/or a needle-wiping element.

Needle sheath

A seal adapted to be fitted over the open end of the barrel of a hypodermic syringe has a cap of a non-latex elastomer having a central aperture which is sufficiently small as ordinarily to retain liquid therebehind but which can be deformably expanded to allow passage of the rearward end of a needle hub for engagement with the barrel.
