摘要:
An inflatable thermal blanket (100) with a multilayer sheet (104) and a method of use are disclosed for delivering thermally-controlled air to a person. The apparatus includes an inflatable structure formed from joining a first sheet and a second sheet. An inlet (108) is provided into the inflatable structure for receiving thermally-controlled air. A multilayer sheet, made from a plurality of sheets (106) releasably attached together, is attached to the second sheet. Means are provided for exhausting the thermally-controlled air from the inflatable thermal blanket. In the method of use, the inflatable thermal blanket is deployed in a first use and a source of thermally-controlled air is attached to the inflation port (108) admitting thermally-controlled air into the inflatable structure and exhausting thermally-controlled air. Additionally, the inflatable thermal blanket may be reused by detaching the lowest layer (106) of the multilayer sheet, exposing another layer of the multilayer sheet and deploying the inflatable thermal blanket in a second or later use. These steps may be repeated until the last layer (122) of the multilayer sheet is used, when the thermal blanket may be discarded. In an alternate embodiment, when the multilayer sheet is exhausted it is detached and another multilayer base sheet is attached to the inflatable structure and the thermal blanket is used again.
摘要:
A condition is detected between an inlet port of an inflatable thermal device, such as an inflatable thermal blanket, and an end of ain air hose through which a flow of pressurized, thermally treated air is provided to the device by way of the inlet port. The condition may be disconnection of the end of the air hose from the inlet port or a change in the value of an air flow characteristic such as temperature or velocity. A response to the condition may include provision of a perceptible indication that the condition has occured. Other responses may include cessation of the flow of air or changing an air flow characteristic.

An inflatable convective thermal pad (10) is adapted for use under a patient. The pad (10) has a surface on a layer (12) that receives the patient and that provides for the passage of air through the layer and the surface toward the patient. One or more drain openings (16a) or channels are provided in the layer for draining fluid from the layer.

A non-contact controllable heater wound covering and method having a peripheral sealing ring covered by a layer to which is attached a heater and this assembly is attached to the skin with an adhesive so that the heater is held proximate the wound area in a non-contact position. The layer and peripheral sealing ring together define a treatment volume proximate the wound. The wound covering includes a programmable active heater control and the sealing ring may dispense water to control the humidity of the treatment volume. One form of active heat is an electrical resistive filament in variable geometric shapes providing versatility in application of heat to different types of wounds and wound area geometries. Another form of active heat is the transfer of a heated gas to the wound covering.

An airway device for sealing against the laryngeal opening includes an air tube with proximal and distal ends and a sealing member attached to the distal end. The sealing member has a distal portion with a pair of opposing lateral flanges for engaging the cricoid cartilage to laterally align the sealing member with respect to the laryngeal inlet. The sealing member has a compressible anterior surface that contacts and seals against the laryngeal inlet. A tubular extension of the distal end of the air tube projects through and beyond the compressible anterior surface. The sealing member has a pronounced sigmoid shape having a lower section which, together with the tubular extension, creates a hook that provides an end point for accurate cephalad-caudad depth placement of the sealing member against the rim of the laryngeal inlet.

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 drap 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.
摘要:
A laryngeal airway device includes an air tube with proximal and distal ends, and a sealing member attached to the distal end of the air tube. The sealing member includes an anterior surface adapted to seat in the throat, against the hyoid bone, and to stretch the laryngeal inlet. A hole extends through the anterior surface and 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 anterior surface forms a seal that surrounds the hole. Airway patency is thereby ensured.

A non-contact wound treatment device (100) suitable for releasable attachment to a patient's skin surface over a selected wound area in a non-contact position relative to the selected wound area, the wound treatment device (100) comprising an attachment portion (102) suitable for releasable attachment with the patient's skin surface, having an inner perimeter for defining the selected wound area, a wound treatment portion (104) with a substantially planar wound cover (105) and a support member (106) supporting the wound cover (105), and a transition portion (108) with a membrane (110) connecting the wound treatment portion (104) to the attachment portion (102), the membrane (110) extending around the outer perimeter (118) of the support member (106) and attached to the attachment portion (102) between the inner (111i) and outer perimeter (111o) of the attachment portion (102).
