US 9,956,112 B2 · Prewarming gown

Abstract

A device for warming a human body. The device is a gown that has a body with a thorax portion and a leg portion. One embodiment prevents redistribution hypothermia with a distributor attached to the inside of the leg portion. The sleeves, leg portion, and posterior of the gown are heat reflective. The anterior of the thorax portion of the gown is non-reflective. The distributor inflates when heated air is supplied. The distributor exhausts air into the gown. Temperature is maintained at a desired level for the extremities, while preventing the thorax area from being elevated to an uncomfortable level. Another embodiment is a perioperative warming device. The device is a gown that has a thorax portion and a leg portion. Each portion has an independent air chamber and inlet. The two portions are releasably connected. The sleeves, leg portion, and anterior of the gown are heat reflective.

a second inlet defined by a passage in said fourth sheet into said second chamber, said second inlet configured to connect with said air hose;
a connector releasably joining a bottom of said upper body portion and a top of said lower body portion;
and
a plurality of connections between said third sheet and said fourth sheet, said plurality of connections distributed inside a boundary defined by a peripheral edge of said fourth sheet whereby said third sheet is constrained to expand a limited distance from said fourth sheet when said second chamber is inflated with air.

#Not Applicable

#1. Field of Invention

#This invention relates to a system for warming the body of a human. More particularly, this invention pertains to passive warming and active warming before, during, and after surgery or other medical procedures.

Brief description of the drawings17 figures

#The above-mentioned features will become more clearly understood from the following detailed description read together with the drawings in which:

#FIG. 1 is a side view of one embodiment of a warming gown on a standing patient.

Detailed description8,506 words

#A gown 100, 1500 for warming a patient is disclosed. The gown 100, 1500 provides passive warming and active warming of patients before, during, and/or after surgery or other medical procedures. In one configuration, the gown 100 prevents redistribution hypothermia and in another configuration the gown 1500 is suitable for perioperative use. The gown 100, 1500 is intended to be worn by a human 102. For ease in identifying locations, the various anatomical terms of location are used. For example, the superior-inferior axis coincides with the axis from the neck area to the foot area of the gown 100, 1500. The transverse plane is perpendicular to the superior-inferior axis.

#FIG. 1 illustrates a side view of one embodiment of a gown 100 worn by a patient 102 who is standing. FIG. 2 illustrates a rear view of the gown 100. FIGS. 1 and 2 show the gown 100 in a first, or passive, configuration that is suitable for a patient 102 who is mobile. The passive configuration allows the patient 102 to stand, walk, sit, or otherwise move or position himself.

#The gown 100 includes a body 104, a drape 106, and a pair of sleeves 108. The body 104 has a thorax portion 110 and a leg portion 112. The thorax portion 110 is sized and configured to fit loosely around the thorax of the patient 102. The thorax portion 110 encloses the torso of the patient 102 by encircling the patient's body. The thorax portion 110 has an opening 114 through which the neck of the patient 102 extends. With the patient 102 upright, such as when standing or sitting, the gown 100 is supported by the thorax portion 110 of the gown 100 resting on the shoulders of the patient 102.
