This invention provides a female medical coupling port with an integrated port guide to enable more accurate and precise coupling of a male port coupling (such as the cannula of a syringe) and to prevent port exposure to non-sterile objects. The male and female ports can be arranged according to standard dimensions for male and female luer taper fittings recognized by ANSI and by ISO. This guide-shielded port is usable with the standard ANSI and ISO male cannula widely used in the medical field. In an embodiment the female port is used in medical fluid systems to receive a blunt male cannula, such as those found in the luer lock fitting of needle-less syringes and IV tubing systems to establish a mechanical coupling. Female ports allow coupling of devices (e.g. syringes and IV tubing) to a variety of medical applications including stopcocks, minimum fluid displacement medical couplings, female-to-female adapters, port dead-end caps, IV extension sets, pressure-monitoring devices, etc. The port guide can be constructed as a unitary part of the port, or can be a retrofittable structure that is either snapped into place on, for example, a female port stem, or slid onto a port, such as a minimum displacement fluid coupling. Appropriate drain ports can be provided in the port guide to prevent capture of excess fluid.

An intubating LMA construction features a rigid airway tube wherein curvature in a single plane establishes essentially an arcuate path of angular extent in the preferred range of 130°, plus or minus 5°, which I have found to be in substantial anatomical conformance with the adult human's airway path, between a proximal end of the arc at substantial register with the longitudinal midpoint of the hard palate, and a distal end that faces and is at short offset from the glottic aperture, it being understood that my findings apply to suitably quantified allowance for variations in patient-head anatomy, as is for example customary for different sizes of LMA devices, each of which is adapted to serve one of five selected patient-size ranges. The proximal end of the rigid tube is suitably a short straight portion which is tangentially and integrally related to the proximal end of the arc. And the distal end of the arc is fitted with flexible mask structure of preferably elastomeric material such as silicone rubber, wherein an internal ramp formation within the mask structure assures a limited but important measure of further and stabilized guidance of an ET which has emerged from the distal end of the rigid tube, such that unguided displacement of the ET (i.e., beyond the ramp) is oriented to target safe entry of the ET into the glottic opening.
