Abstract
Disclosed herein are facially fitting devices, such as nasal cannulas and oxygen masks, including illuminating placement marker(s), which facilitate correct placement of the facially fitting devices on a face of a subject in dark conditions. The placement marker is powered by a thermo-electric generator, which generates electrical power via thermal coupling thereof to skin on the face of a subject when the facially fitting device is fitted, or partially fitted, on the face of the subject.
Claims20
A facially fitting device for delivering gas to, and/or collecting gas from, a subject, the device comprising:
- a gas port configured to be fluidly connected to an external system for providing and/or collecting gas;
- at least one contact portion, each configured to contact at least one skin surface at, or near, a nose-mouth region, or near a nose, when the device is at least partially fitted on the face of a subject;
- at least one thermo-electric generator (TEG) wherein a first side thereof is exposed or thermally exposed on the least one contact portion, and configured to be powered through a temperature difference between the skin surface and a second side of the TEG;
- and
- at least one light source, powered by the at least one TEG, configured to provide at least one illuminating placement marker and positioned on the device such as to be automatically powered on and to illuminate the nose-mouth region or the nose, and/or parts of the face on sides of the nose, when the device is placed in a worn position.
A method of manufacturing a facially fitting device for delivering gas to, and/or collecting gas from, a subject, wherein the facially fitting device is configured to provide illumination through the Seebeck effect, the method comprising:
- providing a facially fitting device comprising at least one contact portion, said contact portion configured to contact at least one skin surface at, or near, a nose-mouth region, or near a nose, when the device is at least partially fitted on the face of a subject;
- incorporating at least one thermo-electric generator (TEG) into or onto the contact portion such that a first side of the at least one TEG is exposed or thermally exposed on the least one contact portion and configured to be powered through a temperature difference between the skin surface and a second side of the TEG;
- and
- incorporating at least one light source, powered by the at least one TEG to provide at least one illuminating placement marker on the device such as to automatically power on and to enable illumination of the nose-mouth region or the nose, and/or parts of the face on sides of the nose, when the device is placed in a worn position.
