Method for forming custom orthotics
View Patent ↗A method for making custom orthotic devices includes mounting a plastic sheet to a housing. The method also includes receiving, by the plastic sheet, pressure from a body part of a patient. The method further includes directing electromagnetic radiation to a ferrous material mounted within the housing. The electromagnetic radiation heats the ferrous material, which heats the plastic sheet such that the plastic sheets forms into an orthotic device that fits the body part.
1 . A method for making custom orthotic devices, the method comprising:
mounting a plastic sheet to a housing;
receiving, by the plastic sheet, pressure from a body part of a patient; and
directing electromagnetic radiation to a ferrous material mounted within the housing, wherein the electromagnetic radiation heats the ferrous material, which heats the plastic sheet such that the plastic sheet forms into an orthotic device that fits the body part in response to the pressure from the body part of the patient.
2 . The method of claim 1 , further comprising mounting a heat shield to the plastic sheet such that the heat shield is positioned between the plastic sheet and the body part.
3 . The method of claim 2 , further comprising mounting a temperature sensor to the heat shield.
4 . The method of claim 3 , further comprising:
receiving, by a controller, a sensed temperature from the temperature sensor;
comparing the sensed temperature to a temperature threshold; and
responsive to a determination that the sensed temperature exceeds the temperature threshold, lowering a temperature of the heat shield.
5 . The method of claim 4 , further comprising activating, by the controller, a motor to move the plastic sheet away from the electromagnetic source to lower the temperature.
6 . The method of claim 4 , further comprising activating, by the controller, a motor to move the electromagnetic source away from the plastic sheet to lower the temperature.
7 . The method of claim 4 , further comprising turning off the electromagnetic source, by the controller, to lower the temperature.
8 . The method of claim 4 , further comprising pulsing the electromagnetic source, by the controller, to lower the temperature.
9 . The method of claim 1 , wherein the ferrous material comprises ferrous elements, and further comprising embedding the ferrous elements within the plastic sheet.
10 . The method of claim 9 , wherein embedding the ferrous elements comprises positioning the ferrous elements between a top surface of the plastic sheet and a center line of the plastic sheet.
11 . The method of claim 1 , wherein the ferrous material comprises a ferrous metal sheet, and further comprising adjusting, by a controller, a height of the ferrous metal sheet within the housing.
12 . The method of claim 11 , wherein the height of the ferrous metal sheet is adjusted based at least in part on a sensed distance between the plastic sheet and the ferrous metal sheet.
13 . The method of claim 1 , further comprising mounting a distance sensor on or within the housing to determine distances between components within the housing.
14 . The method of claim 13 , further comprising comparing a sensed distance, obtained by the distance sensor, between the plastic sheet and the electromagnetic source to a desired distance between the plastic sheet and the electromagnetic source.
15 . The method of claim 14 , further comprising moving, responsive to a determination that the sensed distance differs from the desired distance, the electromagnetic source or the plastic sheet to achieve the desired distance.
