Abstract: Distinctly keyed male-female couplers are pneumatically connected to medical ventilator by distinct lines carrying pulsatile gas or sensory signals. Ventilator-mounted female coupler has entranceway cavity and larger receiving cavity delimited by catch edge. Male fence-forming longitudinal winglets extend from sealing plate carry terminal end convexities which latch onto catch edge. Winglets move inward due to larger fence circumference than entranceway and seat on catch. Winglets placed in tension due to locking length less than entranceway span, then convert force into sealing compressive force between sealing plate and female tube end. Conjoining male tube bayoneted and sheathed by projecting female tube, resulting in another gas seal. Two compressive seals formed between male distal port and pneumatic line. Extending male key(s) on winglet insertable into matching female slots. Convexities block insertion of non-matching couplers set due to interference by convexities on female on entranceway edges.

Abstract: The present invention provides compositions comprising a gas and a gastrointestinal smooth muscle relaxing agent comprising ethyl nitrite in a therapeutically effective amount. The present invention also provides methods of relaxing gastrointestinal smooth muscle, alleviating contraction or spasm of gastrointestinal smooth muscle to facilitate a diagnostic medical procedure and treating or preventing a gastrointestinal disorder using the compositions of the invention.

Abstract: The invention relates generally to methods for preventing post endoscopic retrograde cholangiopancreatography pancreatitis (ERCP). The method comprises administering a therapeutically effective amount of a pharmaceutical composition comprising secretin and a pharmaceutically acceptable carrier.

Abstract: A light outputting device comprises; a containment (14) for housing an element for emitting light (11); at least one axially extending light conducting element (13) having an axial length substantially greater than its width transverse the axis; the light conducting element (13) being aligned axially with the element for emitting light (11) by means of the containment (14) or an extension thereof; the, or each, light conducting element (13) having a light input region such as an end face whereby light generated by the element for emitting light (11) is caused to pass axially into the or each light conducting element (13) by way of its associated light input region. Typically the axial length of the light conducting element (13) is at least three times its width transverse the axis.
