Title: Laryngeal mask with large-bore gastric drainage
Inventor: BRAIN ARCHIBALD IAN JEREMY
IPC: A61M16/04
Filed: 2000-10-09
Abstract: An artificial airway device (20) for use in unconscious patients comprises a laryngo-pharyngeal mask (52) including a roughly elliptical expandable masking ring (55). The expandable mask sealingly surrounding the laryngeal inlet (50) when expanded to obstruct communication between the laryngeal inlet and oesophagus (37). One or more airway tubes (125, 127) connected to the mask provide for fluid flow to a portion of the mask facing the laryngeal inlet when the mask sealingly surrounds the laryngeal inlet. A gastro-tube (75) connected to the mask is bonded along most of its length to the airway tube(s) and provides a fluid flow-path to the surface of the mask facing the oesophagus when the mask sealingly surrounds the laryngeal inlet. The cross-section area of the gastro-tube is at least as great as that of the airway tube(s). The distal end of the gastro tube passes through the masking ring at its narrower distal region (62) where, when installed in a patient, it abuts the oesophagus; and the distal portion (80) of the gastro-tube (75) flattens when the mask is deflated to facilitate smooth passage behind the larynx during insertion through the patient's airway (22).

Title: Estimation of cardiac ejection fraction and end diastolic volume
Inventor: MCKOWN RUSSELL
IPC: A61B5/028
Filed: 2000-12-01
Abstract: The invention estimates a cardiac performance value such as cardiac output (CO) and cardiac ejection fraction (EF) by sensing a downstream indicator concentration signal y(t) that corresponds to an indicator (preferably heat) signal x(t) injected upstream in a patient's blood channel. The signal x(t) is preferably generated as a series of alternating transitions between a high state and a low state, such as a PRBS signal. The signal y(t) is then divided into at least one sub-signal that is synchronous with x(t).  A decay parameter .tau. that minimizes a cost function that includes a time-domain channel relaxation model is then calculated. The cardiac performance value is then calculated based on this value for .tau..  For each transition of the injected indicator signal, a corre-sponding segment of the indicator concentration signal is preferably isolated, and a segment relaxation parameter is then calculated.  The decay parameter .tau. is then estimated as a predetermined function of the segment relaxation parameters. In embodiments of the invention in which x(t) is periodic, the invention also generates estimates of .tau. by finding the minimum of a cost function between a model of the channel and an average of several cycles of y(t), each corresponding to one period of x(t).
