Abstract

A method for warming a person perioperatively using a warming device including a clinical garment having an inside surface supporting a convective apparatus with stacked, separately-inflatable sections includes inflating one of the stacked sections of the convective apparatus to provide comfort warming by convection or inflating another of the stacked sections of the convective apparatus to provide therapeutic warming by convection.

Claims

1. A method for warming a person perioperatively using a warming device including a clinical garment and an inflatable convective apparatus supported on an inside surface of the clinical garment, the inflatable convective apparatus constituted of stacked, separately inflatable sections, the method comprising:

dressing a person with the clinical garment preoperatively;

coupling a comfort warming section of the convective apparatus to a first source of warmed pressurized air;

inflating the comfort warming section with the warmed pressurized air;

circulating warmed air from the comfort warming section to the interior of the clinical garment; and

venting warmed air from a first side of the convective apparatus through the convective apparatus to a second side of the convective apparatus.

2. The method of claim 1, wherein the comfort warming section faces the inside surface, and the act of circulating includes circulating warmed air from the comfort warming section toward the inside surface.

3. The method of claim 2, further including:

decoupling the comfort warming section from the first source of warmed pressurized air;

coupling a therapeutic warming section of the convective apparatus to a second source of warmed pressurized air;

inflating the therapeutic warming section with the warmed pressurized air; and

circulating warmed air from the therapeutic warming section to the interior of the clinical garment.

4. The method of claim 3, wherein the therapeutic warming section faces the interior of the clinical garment, and the act of circulating includes circulating warmed air from the therapeutic warming section toward the interior of the clinical garment.

5. A method for warming a person using a warming device including a clinical garment and an inflatable convective apparatus supported on an inside surface of the clinical garment, the inflatable convective apparatus constituted of stacked, separately inflatable sections having a common permeable surface, the method comprising:

dressing a person with the clinical garment preoperatively;

coupling a comfort warming section of the convective apparatus to a first source of warmed pressurized air;

inflating the comfort warming section with the warmed pressurized air;

circulating warmed air from the comfort warming section through a portion of the common permeable surface to the interior of the clinical garment; and

decoupling the comfort warming section from the first source of warmed pressurized air;

coupling a therapeutic warming section of the convective apparatus to a second source of warmed pressurized air;

inflating the therapeutic warming section with the warmed pressurized air; and

circulating warmed air from the therapeutic warming section through substantially all of the common permeable surface to the interior of the clinical garment.

6. The method of claim 5, wherein the common permeable surface faces the inside surface, and each act of circulating includes circulating warmed air toward the interior of the clinical garment.

7. A method for warming a person perioperatively using a warming device including a clinical garment and an inflatable convective apparatus supported on an inside surface of the clinical garment, the inflatable convective apparatus constituted of stacked, separately inflatable sections, the method comprising:

dressing a person with the clinical garment preoperatively;

coupling a comfort warming section of the convective apparatus to a first air hose having a first diameter;

providing a flow of warmed pressurized air to the comfort warming section through the first air hose;

inflating the comfort warming section with the warmed pressurized air;

circulating warmed air from the comfort-warming section to the interior of the clinical garment; and

venting warmed air from a first side of the convective apparatus through the convective apparatus to a second side of the convective apparatus.

8. The method of claim 7, wherein the comfort warming section faces the inside surface, and the act of circulating includes circulating warmed air from the comfort warming section toward the inside surface.

9. The method of claim 8, further including:

decoupling the first air hose from the comfort warming section;

coupling a therapeutic warming section of the convective apparatus to a second air hose having a second diameter larger than the first diameter;

providing a flow of warmed pressurized air to the therapeutic warming section through the second air hose;

inflating the therapeutic warming section with the warmed pressurized air; and

circulating warmed air from the therapeutic warming section to the interior of the clinical garment.

10. The method of claim 9, wherein the therapeutic warming section faces the interior of the clinical garment, and the act of circulating includes circulating warmed air from the therapeutic warming section toward the interior of the clinical garment.

11. A method for warming a person using a warming device including a clinical garment and an inflatable convective apparatus supported on an inside surface of the clinical garment, the inflatable convective apparatus constituted of stacked, separately inflatable sections having a common permeable surface, the method comprising:

dressing a person with the clinical garment preoperatively;

coupling a comfort warming section of the convective apparatus to a first air hose having a first diameter;

providing a flow of warmed pressurized air to the comfort warming section through the first air hose;

inflating the comfort warming section with the warmed pressurized air;

circulating warmed air from the comfort warming section through a portion of the common permeable surface to the interior of the clinical garment; and

decoupling the first air hose from the comfort warming section;

coupling a therapeutic warming section of the convective apparatus to a second air hose having a second diameter larger than the first diameter;

providing a flow of warmed pressurized air to the therapeutic warming section through the second air hose;

inflating the therapeutic warming section with the warmed pressurized air; and

circulating warmed air from the therapeutic warming section through substantially all of the common permeable surface to the interior of the clinical garment.

12. The method of claim 11, wherein the common permeable surface faces the inside surface, and each act of circulating includes circulating warmed air toward the interior of the clinical garment.
