Publication number: 20180192873Abstract: A physiological monitoring system comprising a sensor device for attachment to the skin of a subject, the sensor device comprising at least a first sensor for sensing a physiological parameter of the subject and a processing device configured for analysing data sensed by the sensor by means of a predetermined algorithm to estimate whether the data is indicative of a disease condition, and on detecting such a condition to generate an alert. It is further described a method for monitoring a plurality of subjects comprising the step of providing each subject with a sensor device as referred to above and then analysing data sensed by the sensors such as to preferentially generate an alert if the data received from multiple ones of the sensors demonstrate a contemporaneous trend indicative of a disease condition.Type: ApplicationFiled: October 23, 2015Publication date: July 12, 2018Inventors: Oriane Elisabeth CHAUSIAUX, Matthew Neil SARKAR, Shamus Louis Godfrey HUSHEER

Patent number: 9125998Abstract: An inhaler for producing an inhalable aerosol of powdered medicament is disclosed. The inhaler includes an aerosolizing device having a chamber of substantially circular cross-section, inlet and outlet ports at opposite ends of the chamber for the flow of drug laden air through the chamber between said ports and, a bypass air inlet for the flow of clean air into the chamber. The bypass air inlet is configured so that air entering the chamber through said inlet forms a cyclone in the chamber that interacts with the drug laden air flowing between the inlet and outlet ports.Type: GrantFiled: January 14, 2009Date of Patent: September 8, 2015Assignee: Vectura Delivery Devices LimitedInventors: Quentin John Harmer, Ivan Milivojevic, Matthew Neil Sarkar

Patent number: 7854226Abstract: A powder inhaler includes a container for storing powdered medicament. A metering member has a dosing recess and is moveable between a filling position in which the dosing recess is in alignment with an opening of the container, and an inhalation position in which it is in alignment with an inhalation channel. A mouthpiece is in communication with the inhalation channel for enabling inhalation of the dose of powdered medicament when in the inhalation position. A protective member provided between the metering member and the inhalation channel is moveable between a closed position in which the protective member covers the dosing recess, thereby preventing powdered medicament contained in the dosing recess from entering the inhalation channel, and an open position in which the protective member does not cover the dosing recess, thereby exposing the dosing recess to the inhalation channel for enabling inhalation of the dose of the powdered medicament.Type: GrantFiled: April 20, 2006Date of Patent: December 21, 2010Assignee: Chiesi Farmaceutici S.p.A.Inventors: John Pinon, Sameer Shirgaonkar, Christopher James Smith, Simon Burge, Max William Middleton, David Ahern, Matthew Neil Sarkar, Ben Arlett, Emma Lesley Lye, Simon Smith

Publication number: 20080115785Abstract: An inhaler for producing an inhalable aerosol of a powdered medicament includes an aerosolizing device in the form of a vortex chamber 1. The vortex chamber 1 has a tangential inlet port 3 and an axial port 2. The ratio of the diameter of the vortex chamber 1 to the diameter of the exit port 2 is between 4 and 12. The length of the exit port 2 is less than its diameter. The cross-section of the inlet port 3 is rectangular and is defined at the bottom and at the radially outermost edge by the walls of the vortex chamber 1. The cross-sectional area of the inlet conduit 7, which supplies the medicament in a gas flow to the inlet port 3, decreases in the direction towards the vortex chamber 1. The inlet conduit 7 may be curved. The inhaler is capable of repeatably producing an aerosol of a medicament with a high proportion of particles in the range 1 to 3 microns, while using a 20 relatively small amount of energy.Type: ApplicationFiled: October 31, 2007Publication date: May 22, 2008Applicant: Vectura Delivery Devices LimitedInventors: Stephen William Eason, Quentin John Harmer, Matthew Neil Sarkar, John Pinon, Michael John Dunkley, Roger William Clarke, Stephen Henry Hill

Patent number: 6948496Abstract: An inhaler for producing an inhalable aerosol of a powdered medicament comprises a cyclone (1) with a tangential air inlet (3) and an axial air outlet (4). The cyclone (1) aerosolises and retains an aerosol of powdered medicament in an airflow circulating between the inlet (3) and the outlet (4). The cyclone (1) has an exit port (2) which is open to atmosphere. When the aerosol is to be inhaled, the pressure in the cyclone (1) is increased by increasing the airflow to the inlet (3) which causes the aerosol to discharge through the exit port (2). The inhaler has the advantage that the rate of discharge of the aerosol can be controlled independently of the rate of airflow required to aerosolise the medicament.Type: GrantFiled: July 20, 2001Date of Patent: September 27, 2005Assignee: Vectura, LimitedInventors: Stephen William Eason, Quentin John Harmer, Matthew Neil Sarkar
