  • Publication number: 20040221370
    Abstract: A headband having a low stretch segment sized to fit around a wearer's head, and an elastic segment being smaller than the low stretch segment, and having a free end and an attached end, where the elastic segment is attached at its attached end with the low stretch segment. The headband also includes a tab portion having a first end and a second end, the first end of the tab portion being connected with the free end of the elastic portion, the second end of the tab portion configured to form a closed loop with the low stretch segment, around the wearer's head. The headband also includes visual indicator configured for monitoring the extended position of elastic segment and optionally a stop portion that is configured to engage against the elastic segment to limit its stretch.

  • Publication number: 20040199063
    Abstract: An optical sensor having a cover layer, an emitter disposed on a first side of the cover, a detector disposed on the first side of said cover, and a plurality of stacked independent adhesive layers disposed on the same first side of the cover, wherein the top most exposed adhesive layer is attached to a patient's skin. Thus, when the sensor is removed to perform a site check of the tissue location, one of the adhesive layers may also be removed and discarded, exposing a fresh adhesive surface below for re-attachment to a patient's skin. The independent pieces of the adhesive layers can be serially used to extend the useful life of the product.

  • Patent number: 6763255
    Abstract: A pulse oximeter sensor having an emitter(s) and a detector, with a layer having a first portion of the emitter and a second portion of layer over the detector is provided. A barrier is included between the first and second portions of the overlying layer to substantially block radiation of the wavelengths emitted by the emitter(s). Preferably, the barrier reduces the radiation shunted to less than 10% of the radiation detected, and more preferably to less than 1% of the radiation detected.

  • Publication number: 20040117891
    Abstract: A headband with a tension indicator having an elastic segment sized to fit around a wearer's head; and a non-elastic segment being smaller than and attached with the elastic segment. The non-elastic segment is sized to span a portion of the elastic segment when the elastic segment is stretched, and the non-elastic segment is larger than the portion of the elastic segment it spans when the elastic segment is not stretched. The non-elastic segment is attached with the elastic segment in such a manner that the non-elastic segment projects out from the surface of the elastic portion when the headband is not sufficiently tight, thus creating a loop which provides a visual indication that the headband needs re-tightening.

  • Patent number: 6112107
    Abstract: A flexible sensor with strain relief on electrical contacts. Wires are attached to the electrical contacts, then a bulge of material is deposited over them, such as an adhesive. The wires are then bent back over the top of the bulge and secured. This prevents any tugging on the cable from pulling directly on the attachment of the wires to the contacts.
