Abstract: A device for improving flow of air through a nasal cavity of a wearer during activity such as cycling or running or like exercise substantially minimizing air flow resistance, the device including a substantially U-shaped body forming a bridge for spanning adjacent nasal cavities of a wearer; a first adjustable body and a second adjustable body mounted to opposite upright portions of the U-shaped body, the first and second bodies each having: a belt adjustable about an attachment mount on an upright portion of the U-shaped body; a rib extending outwardly and arcuately from a portion of the U-shaped body distal to the bridge, the each rib ending in a relatively large surface area portion connected to a portion of the belt, the large surface area portion of the each rib adapted for abutting internal wall surfaces of the nasal cavity of a wearer, and wherein the belt and rib form an open channel defining an air flow pathway within the nasal cavity; and whereby in an operating condition the belt or belts is tight

Abstract: A connector for use with a medical device is provided. The connector comprises a body portion having a first end and a second end. The body portion includes an internal channel extending along a length of the body portion providing fluid communication between the first end and the second end and a coupling connected to the body portion. The coupling comprises a first bracket arranged to receive a motor housing, wherein the first end is arranged to connect to an instrument body of the medical device and the second end is arranged to connect to an instrument tip of the medical device.

Abstract: There is disclosed herein a device for improving flow of air through the nasal cavity of wearer of the device, the device comprising a substantially U-shaped body forming a bridge for spanning the nostrils of a wearer when the device is in use; and a first body and a second body interconnected with opposite upright portions of the U-shaped body, each comprising a rib which extends outwardly from a portion of the U-shaped body distal to the bridge and ends in a section provided with padding which forms a relatively large surface area portion, wherein the first and second bodies are adjustable such that each relatively large surface area portion can be urged against a nostril wall, whereby resistance to flow of air is substantially reduced.

Abstract: The present invention relates generally to new surfaces for solid phase chemistry applications, more specifically plastics surfaces modified by graft polymerisation for use in chemical synthesis and/or immobilisation of chemical entities and/or compounds.

Abstract: New surfaces for solid phase chemistry applications are disclosed, specifically plastics surfaces modified by graft polymerization for use in chemical synthesis and/or immobilization of chemical entities and/or compounds. In particular, an activated modular grafted polymeric surface is disclosed which is suitable for use as a reagent for solid phase organic synthesis, or as a reagent for the affinity capture, presentation or preparation of biomolecules such as proteins, oligonucleotides, nucleic acids, peptides, and lectins. The grafted polymeric surfaces are particularly useful as scavenger reagents in combinatorial synthetic protocols, and as affinity reagents in protein purification and proteomics.
