Abstract
A warming device includes a clinical garment having an inside surface supporting a convective apparatus with separately-inflatable sections, each adapted to enable a particular mode of warming. Each section has a surface or region with a permeability that varies from the permeability of a surface or region in another section.
Claims22
A warming device, comprising:
- a clinical garment with an inside surface;
- and
- a convective apparatus supported on the inside surface;
- the convective apparatus including a first section adapted to provide comfort warming by convection through a first permeable surface and a second section adapted to provide therapeutic warming by convection through a second permeable surface;
- the first permeable surface including a first region with a first permeability;
- and
- the second permeable surface including a second region with a second permeability greater than the first permeability;
- wherein the first and second sections are separately inflatable.
A warming device, comprising:
- a clinical garment with an inside surface;
- and
- a convective apparatus supported on the inside surface;
- the convective apparatus including dual sections to provide comfort warming by convection through a surface having a first mean permeability and therapeutic warming by convection through a surface having a second mean permeability higher than the first mean permeability;
- wherein the dual sections are separately inflatable.
A warming device, comprising:
- a clinical garment with an inside surface;
- and
- a convective apparatus supported on the inside surface;
- the convective apparatus including two separately inflatable sections;
- and
- the convective apparatus including a permeable member shared by the sections for emitting air;
- the permeable member having at least one region of low permeability in a first section and at least one region of high permeability in the second section.
A method for warming a person perioperatively using a warming device constituted of a clinical garment and a dual-section convective apparatus supported on an inside surface of the clinical garment, comprising:
- dressing a person with the clinical garment preoperatively;
- coupling a first section of the convective apparatus to a first source of warmed pressurized air;
- convectively warming the person for comfort by way of a surface of the first section having a first permeability
- decoupling the first section from the first source;
- coupling a second section of the convective apparatus to a second source of warmed pressurized air;
- and
- convectively warming the person for therapy by way of a surface of the second section having a second permeability higher than the first permeability.
