Publication number: 20110257632Abstract: In the field of pain relief and treatment there is a need for a device which is able to administer several predetermined doses of an opioid analgesic in a manner which can be done simply and safely by a patient or carer; in particular in a manner which minimises the risk of administering too great a dose at any one time. A device (10), for administering a predefined number (N) of predefined volume unit doses (Vu) of an opioid analgesic in liquid form, includes a closed container (12) which contains a predetermined fill volume (Vf) of the opioid analgesic, and a dispenser (14) that is connected to the container (12). The dispenser (14) is operable to administer an individual one volume unit dose (Vu) repeatedly said predefined number of times (N). Both the dispenser (14) is adapted, and the concentration of said opioid analgesic is chosen such that said volume unit dose is in the range 0.05 to 0.15 ml.Type: ApplicationFiled: September 28, 2009Publication date: October 20, 2011Applicant: ARCHIMEDES DEVELOPMENT LTD.Inventors: Jonathan Castile, Peter Watts, Alan Smith
