Abstract
A sensor for trans-illumination of a blood perfused portion of a patient. The sensor includes a flexible, initially substantially planar web-like support structure which has an adhesive layer on an upper surface thereof and a loop fabric backing on a lower surface thereof, a light source and a photo-sensor are mounted to the adhesive layer and a compressible foam layer having apertures which overlie the light source and the photo-sensor is mounted to the adhesive layer. A hook fabric tab is mounted to one end of the web-like support structure so that the web-like support structure maybe wrapped around and secured to a patient's finger, toe, hand or foot.
Claims8
A non-invasive electro-optical sensor for removable attachment to a patient for use in measuring light extinction during trans-illumination of the blood perfused tissue within the patient, said sensor comprising:
- a flexible, initially substantially planar web-like support structure having an adhesive layer on an upper surface thereof and a loop fabric backing on a lower surface thereof;
- a light source mounted on said adhesive layer of said substantially planar web-like support structure, said light source having a light emitting surface facing away from said web-like support structure;
- a photo-sensor mounted on said adhesive layer of said substantially planar web-like support structure, said photo-sensor having a light responsive surface facing away from said web-like support structure;
- a compressible foam layer mounted on said adhesive layer of said flexible, initially substantially planar web-like support structure, said compressible foam layer having a first aperture overlying said light source and a second aperture overlying said photo-sensor;
- and
- a hook fabric tab attached at one end of said flexible, initially substantially planar web-like support structure.
