Abstract: A surgical barrier device includes an inflatable thermal blanket formed integrally with, or attached to, a surgical drape. The inflatable thermal blanket is inflatable through an inlet by a thermally-controlled inflating medium. An aperture array on the undersurface of the inflatable thermal blanket exhausts the thermally controlled inflating medium from the inflatable thermal blanket. The surgical drape extends from the inflatable thermal blanket and is sized to substantially cover the entirety of the patient's body. Where patient access is required, the drape has an opening to provide access to a surgical site.

Abstract: A laryngeal airway device includes an air tube with proximal and distal ends, and a padded sealing member attached to the distal end of the air tube. The sealing member is padded on its anterior surface and is adapted to seat in the throat, against the hyoid bone, and to stretch the laryngeal inlet. A hole extends through the anterior surface padding of the sealing member and communicates through an air passage with the distal end of the air tube. When the sealing member is seated in the throat, the hole is contained within the rim of the stretched laryngeal inlet, with which the padded surface forms a seal that surrounds the hole. Airway patency is thereby ensured.

The recess forms the head end of the covering into a pair of flaps, each flap being adapted to extend along a respective side of the patient's head and the covering below the recess being adapted to cover the patient's chest or body area. The recess also forms the plenum chamber into a main plenum chamber for the chest area and a pair of secondary plenum chambers, each secondary plenum chamber being in a respective flap for the head area. The covering has an inlet opening for receiving a gaseous medium for inflating the main plenum chamber and the secondary plenum chambers.

The non-furled portion of each thermal blanket is allowed to inflate and cover a patient. Prior to inflation, the furled portion of each thermal blanket defines a thermal blanket edge with demarcates an access area for a surgical procedure.

The gas may be used, for example, to inflate a thermal care apparatus that exhausts the gas through a plurality of exhaust ports about a patient to envelop the patient in a warm bath. In one embodiment, the container is inserted into an inflatable chamber of the apparatus, and sealably held in place by a resilient aperture structure. In another embodiment, the container is inserted into through the aperture structure into a fluid supply hose that brings temperature-conditioned gas to the apparatus from a source. The aperture structure may comprise, for example, a selected pattern of perforations defined in the chamber or hose, or a layering of resilient material affixed to the chamber or hose with a suitably shaped aperture for receiving the container.

Abstract: An IV fluid warmer that utilizes a warmed airstream supplied through an air hose to heat IV fluid flowing through one or more helically coiled warming tubes positioned within the air hose. In one embodiment, support unit keeps the one or more warming tubes in the air hose, exposed to the warmed airflow. A nozzle provided on the distal end of the air hose has an outer housing and an inner ring slidably positioned therein. The outer housing includes an outer slot and the slidable inner ring includes an inner slot. When aligned, the support unit can be inserted through the inner and outer slots and the inner ring may be rotated to lock the support unit into position within the air hose. In another embodiment, helically coiled warming tube is self-supporting within the air hose. The IV fluid warmer can achieve high heating rates and low flow resistance in this configuration. Furthermore, it can utilize an airstream source of heat such as that conventionally used with inflatable thermal blankets.

Abstract: One or more portions of an inflatable thermal blanket that is sized sufficiently to fully cover a patient are gathered and maintained in a non-inflated condition by a closure such that a thermally-controlled inflating medium admitted into the blanket is prevented from being admitted into the gathered portion(s), thereby leaving a primary part of the patient covered and exposing a part of the patient for medical attention. Thereafter the closure can be released to permit the inflating medium to be admitted into the gathered portion such that the gathered portion self-erects and assumes an inflated condition. The released thermal blanket covers the entire patient and bathes the patient in the inflating medium. The closure can be provided as an elongated tape strip with a central perforation that can be separated.
