Support devices and methods of making and using them
Described herein are support devices, which may include medical support devices. In particular, three-dimensional medical (and non-medical) devices from a single layer of material, typically by stamping or pressing (including cold pressing) a sheet of the material to form rigid and complex 3D shapes capable of use for a variety of medical and non-medical purposes. These support devices typically also include an adhesive material allowing the device to be attached to a subject's skin and/or mounted on a surface (e.g., wall, etc.). In particular, described herein are methods of manufacturing, assembling, and using adhesive support devices.
1. A medical device support apparatus having a three-dimensional shape, the apparatus comprising: a body portion comprising a sheet of material, the sheet of material having an elastic modulus of greater than 0.4 GPa, wherein the sheet of material is configured to be deformed from a flat plane to form: a base region extending in the flat plane, the base region having a first thickness; and a cavity region having one or more walls each having a thickness that is less than the first thickness, the cavity region at least partially surrounded by the base region, wherein the one or more walls of the cavity region extends out of the flat plane at an angle that is greater than 90 0 relative to an adjacent base region; and a plurality of ridges or a lattice pattern stamped into the sheet of material to enhance the stiffness of the apparatus wherein the body portion, base region, cavity region, and plurality of ridges or lattice pattern are part of a single monolithic portion of the sheet of material.
2. The apparatus of claim 1 , further comprising an adhesive substrate portion coupled to at least a portion of the base region, wherein the adhesive substrate portion comprises a liner on a face opposite from the base region.
3. The apparatus of claim 1 , wherein a volume of material in any section of a continuous portion of the base region bounded by an arbitrary shape projected on a plane that is parallel to the flat plane is approximately equal to or less than the volume of material in any section of a continuous portion of the cavity region bounded by the arbitrary shape in the plane.
4. The apparatus of claim 1 , further comprising a cut-out section on a wall of the cavity region, wherein the wall is angled greater than 90° relative to the adjacent base region.
5. The apparatus of claim 1 , wherein a ratio of a maximum length of the cavity region in the flat plane to a maximum depth of the cavity region perpendicular to the flat plane is greater than 2:1.
6. The apparatus of claim 1 , wherein the angle of the one or more walls of the cavity region relative to the flat plane is greater than 90° and less than 180° relative to a portion of the base region adjacent to each of the one or more walls.
7. The apparatus of claim 1 , wherein the base region forms a lip of greater than 0.5 mm around the cavity region.
8. The apparatus of claim 1 , wherein the cavity region comprises the lattice pattern extending in parallel to the flat plane to enhance stiffness.
9. The apparatus of claim 1 , wherein the cavity region comprises one or more surfaces having one or more edges, further wherein all of the surfaces of the cavity region have rounded edges.
10. The apparatus of claim 1 , wherein the cavity region extends up from the base region by between about 1 mm and about 50 mm.
11. The apparatus of claim 1 , wherein the sheet of material comprises a polycarbonate, a polyethylene, or polyethylene terephthalate.
12. The apparatus of claim 1 , wherein the cavity region comprises a hub surrounded by the base region.
13. The apparatus of claim 1 , further comprising an opening cut into a top of the cavity region.
14. The apparatus of claim 1 , wherein the cavity region comprises the plurality of ridges extending at least partially up the one or more walls from the base region.
15. The apparatus of claim 14 , wherein the plurality of ridges are arranged symmetrically around the cavity region.
16. A medical device support apparatus having a three-dimensional shape, the apparatus comprising: a body portion comprising a sheet of material, the sheet of material having an elastic modulus of greater than 0.4 GPa, wherein the sheet of material is configured to be deformed from a flat plane to form: a base region extending in the flat plane, the base region having a first thickness; and a cavity region encircled by the base region, the cavity region having one or more walls each having a thickness that is less than the first thickness, wherein the one or more walls of the cavity region extends out of the flat plane at an angle that is greater than 90° relative to an adjacent base region; and a plurality of ridges formed in the one or more walls and extending at least partially up the one or more walls from the base region to enhance the stiffness of the device, wherein the body portion, base region, cavity region, and plurality of ridges are part of a single monolithic portion of the sheet of material.
