Publication number: 20170068785Abstract: A method, an apparatus, and a computer program product for accessing electronic medical records are provided in which a portable computing device uniquely associated with a user authenticates an identification of the user and automatically retrieves information corresponding to the user from electronic healthcare records systems using the identification. The retrieved information may be combined with other information and electronically delivered to a healthcare provider or patient. Delivery may be initiated by the portable computing device and directed to a computing device of a healthcare provider or patient. Exchange of records and other information between the user and the provider is effected using a first channel to provide a network address of the records and cryptographic keys necessary to extract the records, and a second path to deliver the encrypted records. The first path may be implemented using a camera or optical scanner to read an encoded optical image.Type: ApplicationFiled: September 8, 2016Publication date: March 9, 2017Inventors: Bettina Experton, Christopher Burrow, Stephen MICKELSEN

Publication number: 20160302775Abstract: A controlled transfer biological sample material collection device is disclosed which comprises: a body; and a sample collection member for collecting the biological sample material (not shown), the body housing a sample storage medium for generally dry storage of the biological material, the collection member being moveable from an exposed position (shown in FIG. 8) where collection of a biological sample is possible, to a transfer position (shown in FIG. 9) which effects transfer of at least a portion of the collected sample to said medium. The device is characterised in that the body slideably supports the sample collection member, and in that the body or collection member include a ramp-like projection portion (116 FIG. 10) operable to force the collection member into the transfer position against the medium and to effect said transfer as the collection member slides within the body.Type: ApplicationFiled: November 25, 2014Publication date: October 20, 2016Inventors: Cheryl Louise Potts, Peter James Tatnell, Geraint Seymour, Alan Stuart Pierce, Michael John Smith, Samantha Jane Ogden, Neil John Williams, Christopher Burrows, Jared William Harris Evans, Ashley Edward Bryant, Sean Robert Sweeney
