Abstract

A proning device includes a conformable structure that adapts to the shape of a subject, surrounded by a shell that imparts a substantially elliptical or circular cross-sectional shape to an exterior of the device to facilitate rotation of the subject within the device when the device is wrapped around the subject. A low-friction interface may also be provided to further facilitate rotation of the subject. The device advantageously reduces staffing needs for proning a subject while facilitating extended proning and periodic re-orientation of the subject. Also disclosed herein are methods for making and using such a proning device.

First claim

What is claimed is:

1 . A patient proning device including:
a conformable structure shaped and sized to enclose a front and back of a human body while exposing at least a head of the human body along an axis of the conformable structure aligned to the human body when the human body is placed within the conformable structure, the conformable structure including one or more inflatable chambers, and one or more non-stretchable panels enclosing the one or more inflatable chambers; one or more hinges along an edge of the conformable structure that hingeably couple portions of the conformable structure to one another to facilitate opening the conformable structure to receive the human body and closing the conformable structure to enclose the human body; one or more fasteners along an opposing edge of the conformable structure to the one or more hinges to form a clamshell arrangement with the one or more hinges for opening and closing the patient proning device around the human body; and a pressurized fluid source coupled to the one or more inflatable chambers and operable to controllably inflate the one or more inflatable chambers causing the conformable structure to form a substantially cylindrical shape parallel to the axis of the conformable structure aligned to the human body; a low-friction interface on an exterior surface of the conformable structure, the low-friction interface having a low coefficient of friction with a bedding surface, the low-friction interface configured to facilitate a rotation of the conformable structure about the axis on the bedding surface when the conformable structure is positioned on the bedding surface and the conformable structure is enclosed and fastened about the human body.

2 . The patient proning device of claim 1 , further comprising the bedding surface, wherein the bedding surface includes raised edges to resist translation of the conformable structure relative to the bedding surface during rotation of the conformable structure.

3 . The patient proning device of claim 2 , wherein the low friction interface includes a closed loop of a deformable sheet material disposed between the conformable structure and the bedding surface, an interior surface of the closed loop of the deformable sheet material having a self-coefficient of friction for internal contact, wherein a second exterior surface of the closed loop of the deformable sheet material has a coefficient of friction with the conformable structure and the bedding surface greater than the self-coefficient of friction for the internal contact.

4 . The patient proning device of claim 1 , wherein the conformable structure includes resilient flowable pellets.

5 . The patient proning device of claim 1 , wherein the conformable structure includes a bag filled with expandable polystyrene foam pellets.

6 . The patient proning device of claim 1 , wherein the conformable structure includes one or more removable and replaceable pads.

7 . The patient proning device of claim 1 , wherein the conformable structure includes one or more tensioning belts configured to apply radial tension about the conformable structure.

8 . The patient proning device of claim 1 , further comprising a plurality of restraints arranged to secure the human body within the conformable structure.

9 . The patient proning device of claim 1 , further comprising one or more restraints positioned to secure one or more of a wrist, an ankle, an arm, and a torso of the human body to the conformable structure.

10 . The patient proning device of claim 1 , further comprising one or more guide loops coupled to the conformable structure to secure cords or tubes of medical devices coupled to the human body.

11 . The patient proning device of claim 1 , further comprising a plurality of pull elements arranged about an exterior of the conformable structure, the plurality of pull elements shaped, sized, and positioned to facilitate manual rotation of the patient proning device about the axis.

12 . The patient proning device of claim 1 further comprising one or more handles on the conformable structure to facilitate rotating the human body between prone and supine positions.

13 . A system comprising:
a patient proning device including: a conformable structure shaped and sized to enclose a front and back of a human body while exposing at least a head of the human body along an axis of the conformable structure aligned to the human body when the human body is placed within the conformable structure, wherein the conformable structure includes one or more inflatable chambers, and wherein the conformable structure includes one or more non-stretchable panels on a first exterior surface of the one or more inflatable chambers to impart a cross sectional portion of a circle or ellipse to the conformable structure along the axis of the conformable structure aligned to the human body upon inflation of the one or more inflatable chambers; a bedding surface for the patient proning device, the bedding surface including raised edges to resist translation of the patient proning device relative to the bedding surface during rotation of the patient proning device; and a low-friction interface between the first exterior surface of the one or more inflatable chambers of the patient proning device and the bedding surface, the low-friction interface including a closed loop of a deformable sheet material disposed between the patient proning device and the bedding surface, an interior surface of the closed loop of the deformable sheet material having a self-coefficient of friction for internal contact, wherein a second exterior surface of the closed loop of the deformable sheet material has a coefficient of friction with the patient proning device and the bedding surface greater than the self-coefficient of friction for the internal contact.

14 . The system of claim 13 , further comprising a pressurized fluid source coupled to the one or more inflatable chambers and operable to controllably inflate the one or more inflatable chambers.

15 . The system of claim 13 , further comprising a plurality of restraints arranged to secure the human body within the conformable structure.

16 . The system of claim 13 , further comprising a plurality of pull elements arranged about the first exterior surface of the one or more inflatable chambers of the conformable structure, the plurality of pull elements shaped, sized, and positioned to facilitate rotation of the conformable structure about the axis.

17 . The system of claim 13 , further comprising one or more releasably securable fasteners to hold the conformable structure in a wrapped position around the human body.

18 . The system of claim 13 , further comprising one or more mating hook and loop surfaces on the conformable structure to hold the conformable structure in a wrapped position around the human body.

19 . The system of claim 13 , further comprising one or more restraints positioned to secure one or more of a wrist, an ankle, an arm, and a torso of the human body to the conformable structure.

20 . The system of claim 13 , further comprising one or more handles on the conformable structure to facilitate rotating the human body between prone and supine positions while within the conformable structure.
