Title: Laryngeal mask with large-bore gastric drainage
Inventor: BRAIN ARCHIBALD IAN JEREMY
IPC: A61M25/00
Filed: 2000-10-09
Abstract: An artificial airway device for use in unconscious patients comprises a laryngo-pharyngeal mask including an expandable masking ring. The expandable mask sealingly surrounds the laryngeal inlet when expanded to obstruct communication between the laryngeal inlet and oesophagus. One or more airway tubes connected to the mask provide for fluid flow to a portion of the mask facing the laryngeal inlet when said mask sealingly surrounds the laryngeal inlet. A gastro-tube connected to the mask provides a fluid flow-path to the mask when the mask sealingly surrounds the laryngeal inlet. The distal end of the gastro tube passes through the masking ring at its narrower distal region where, when installed in a patient, it abuts against the oesophagus; and the distal portion of the gastro-tube flattens when the mask is deflated to facilitate smooth passage behind the larynx during insertion through the mouth and throat of the patient.

Filed: 1996-12-20
Abstract: Liquid-transfer apparatus, and methodology employing the same, operatively interposable a syringe and a vial, and accommodating both a single-mouth-size (single-size), two-vial transfer procedure, and a two-mouth-size (two-size), two-vial transfer procedure. The apparatus includes a liquid-transfer device having a syringe-coupling end, a vial-coupling end, and liquid-passage structure effectively communicating between these ends. In the case of accommodating a single-mouth-size (single-size), two-vial procedure, only the liquid-transfer device is employed, and the same is sized with a vial-coupling end that is constructed for direct coupling to the top of the single-size vial which is used. In the case of accommodating a two-mouth-size (two-size), two-vial operation, the liquid-transfer device is employed along with a vial-coupling adaptor which is removably receivable in a connected relationship with the vial-coupling end in the device to adapt the same for coupling to the top of a vial having the smaller of the two sizes of vials which are to be employed. Under these circumstances, the entire procedure begins with coupling of the apparatus to a syringe and to the smaller-size vial, with the vial-coupling adaptor connected to the liquid-transfer device's vial-coupling end. Following a liquid-transfer operation with this smaller vial, the same is decoupled, and such decoupling automatically disconnects the vial-coupling adaptor and the liquid-transfer device. Thereafter, a vial of the larger size is coupled to the vial-coupling end in the liquid-transfer device, and a transfer procedure is completed between the syringe and the larger coupled vial. <IMAGE>
