20090145236 | DEVICE AND METHOD FOR PRESSURE INDICATION - A device that indicates an internal pressure of an inflatable medical cuff. The device includes a membrane movable in response to a difference between an internal pressure of the device and an external pressure. The device includes a movable internal pressure indicator. The movable internal pressure indicator is operably associated with at least a portion of the membrane. | 06-11-2009 |
20120186510 | PRESSURE INDICATOR - A pressure indicator: a body having a pressure chamber which has an inlet for communication with a fluid; a resilient diaphragm having a periphery sealed against the body and having one side thereof exposed to the fluid within the chamber; an indicating arm having an inner end which is integrally formed with the other side of the diaphragm and an outer end arm which is adjacent to a scale, the arrangement being such that pressure of the fluid within the chamber causes resilient deformation of the diaphragm which in turn causes the outer end of the arm to move relative to the scale thereby indicating the pressure of the fluid in the chamber. | 07-26-2012 |
20130303987 | VALVE TO PREVENT AIR ENTERING AN INTRAVENOUS CIRCUIT - A valve for use with a container having intravenous liquid therein, the valve including: a valve body including a valve chamber formed therein; an inlet in fluid communication with the valve chamber; means for connecting the inlet, in use, to the container so that liquid can flow through the inlet to said valve chamber; an outlet having means for connection, in use, to a catheter for intravenous delivery of the liquid; the outlet including an outlet port which opens to said chamber, the port being surrounded by a valve seat; a diaphragm; mounting means for mounting the diaphragm to the body so that a peripheral edge or edge region sealingly engages the body and closes said chamber and such that the diaphragm sealingly engages the valve seat; the arrangement being such that, in use, the head of liquid within the container unseats the diaphragm from the valve seat so that the liquid flows to said outlet but when the level of liquid in the container falls to a predetermined level the diaphragm sealingly engages the valve seat to stop further flow of liquid to the outlet. | 11-14-2013 |
20140034060 | ARTIFICIAL AIRWAY - An artificial airway including an airway tube having proximal and distal ends and a mask mounted at the distal end of the airway tube characterized in that the airway tube includes a curved portion adjacent to its distal end and a straight portion extending from the curved portion to the proximal end of the airway tube and the curved portion is more rigid than the straight portion. | 02-06-2014 |

20090013787 | Hearing testing device - A hearing testing device ( | 01-15-2009 |
20110230786 | HEARING TESTING DEVICE - A portable wireless hearing testing device, the device including: left and right earpieces connected together by a headband and arranged as headphones; the left and right earpiece each including an earpiece housing shaped to surround the left and right ears of a subject respectively to substantially prevent ambient sounds reaching the ear of the subject; left and right loudspeakers located within the left and right earpiece housings respectively; and control circuitry located within the left and/or right earpiece housings and coupled to drive the loudspeakers, the control circuitry being arranged to produce left and right test signals which are applied to the left and right loudspeakers respectively, the test signals being operative to cause the left and right loudspeakers to provide a respective series of tones at frequencies corresponding to the test signals and wherein the test signals do not include significant harmonic components of the tones. | 09-22-2011 |
20120174929 | ARTIFICIAL AIRWAY - An artificial airway including: an airway tube including at least one airway conduit; an inflatable cuff mounted on a distal end of the tube; a support member extending into the cuff, the cuff having inner side walls, anterior walls and a posterior wall, the inner side walls being joined to the support member to define a recess which communicates with the airway conduit, the anterior walls and posterior wall, sealingly engaging, in use, about the glottic opening and posterior pharyngeal wall respectively of a patient. | 07-12-2012 |
