摘要： A finger sensor for a pulse oximetry system is provided having a body of flexible, resilient polymeric material formed as a pocket. On the inside walls of the pocket toward the closed end are a LED light source and an opposing photodetector. The space within the pocket transverse to the longitudinal dimension of the pocket exhibits a relatively smaller width and a relatively greater width. As a finger is inserted into the pocket with the fingertip between the LED and the photodetector, the relatively smaller width of the pocket expands and the relatively greater width of the pocket decreases. This expansion and decrease of the pocket dimensions are resisted by the resilient polymeric material, causing the walls of the pocket containing the LED and the photodetector to securely contact and retain the finger within the pocket. The pocket preferably comprises a pocket having major walls containing the light source and photodetector adjoined on the longitudinal sides of the sensor by expansive side panels which expand and contract to engage fingers of varying sizes.

摘要： An optical sensor, for positioning and holding an optical source and optical detector on opposite sides of a patient's finger or other extremity includes a clothespin-like housing having opposed housing members. The optical source and optical detector are embedded, respectively, in separate, opposed contact pads. The contact pads are mounted on the opposed housing members. A detent mechanism and a carrier associated with each of the housing members and contact pads allows the contact pads to be detached from the housing for cleaning or repair. A pivot mechanism that permits limited lateral as well as rotational movement of the housing members relative to each other allows the sensor to accommodate fingers of varying sizes.

摘要： A device for holding a heartbeat sensor in a relatively fixed relationship with respect to the end of a user's fingertip. More particularly, a device is disclosed wherein a single sheet of resilient material is formed into a base portion for holding the heartbeat sensor and three resilient bands that extend upwardly therefrom. The bands are adapted to grip the user's fingertip. In one embodiment of the invention, the bands and base portion define a U-shaped channel of constant cross-sectional area. In this embodiment a holding structure for the heartbeat sensor is wedge-shaped, the wedge-shaped holding structure being adapted to be held by the base portion so that the cross-sectional area defined by each band and the wedge-shaped holding structure decreases along the longitudinal length of the base portion. In another embodiment of the invention, each band defines a smaller cross-sectional area with respect to the base portion. Thus both embodiments result in more pressure being applied to the sensor at the portion of the user's fingertip closest to the end.
摘要翻译： 一种用于将心跳传感器保持在相对于用户指尖末端相对固定关系的装置。 更具体地，公开了一种装置，其中单片弹性材料形成为用于保持心跳传感器的基部和从其向上延伸的三个弹性带。 乐队适应于抓住用户的指尖。 在本发明的一个实施例中，带和基部限定了恒定横截面面积的U形通道。 在该实施例中，用于心跳传感器的保持结构是楔形的，楔形保持结构适于由基部保持，使得由每个带和楔形保持结构限定的横截面积沿着 基部的纵向长度。 在本发明的另一个实施例中，每个带限定相对于基部的较小的横截面面积。 因此，两个实施例导致更多的压力被施加到最靠近端部的用户指尖部分处的传感器。

摘要： A sensor for measuring the oxygen saturation of blood flow within the skull is described. In a first embodiment the sensor comprises a photodetector and a pair of light emitting diodes surface mounted near the end of a length of flexible printed wiring. The sensor is hermetically sealed by a coating of rubber or polymeric material which has an optical window over the photodetector and light emitting diodes. The sensor is inserted through a burr hole drilled in the skull and slides between the skull and the dura of the brain. The light emitting diodes are pulsed to illuminate blood within the dura and brain with light, and light reflected by the blood is received by the photodetector and converted to electrical signals. The signals are processed by a pulse oximeter to provide an indication of blood saturation. In a second embodiment the photodetector and light emitting diodes are mounted at the end of a core of compressible foam extending from the end of a hollow bone screw. As the bone screw is screwed into a burr hole in the skull the photodetector and light emitting diodes will contact the dura and the foam will compress to maintain optical contact between the electrical components and the dura. Light from the diodes is reflected by blood in the dura and brain, received by the photodetector, and the resultant electrical signals are processed by the pulse oximeter.

摘要： A sensor for measuring the oxygen availability of blood flow within the skull is described. In a first embodiment the sensor comprises a photodetector and a pair of light emitting diodes surface mounted near the end of a length of flexible printed wiring. The sensor is sealed by a coating of rubber or polymeric material which has an optical window over the photodetector and light emitting diodes. The sensor is inserted through a burr hole drilled in the skull and slides between the skull and the dura of the drain. The light emitting diodes are pulsed to illuminate blood flow in the brain beneath the dura with light, and light reflected by the blood is received by the photodetector and converted to electrical signals. The signals are processed by a pulse oximeter to provide an indication of blood availability. In a second embodiment the photodetector and light emitting diodes are mounted at the end of a core of compressible foam extending from the end of a hollow bone screw. As the bone screw is screwed into a burr hole in the skull the photodetector and light emitting diodes will contact the dura and the foam will compress to maintain optical contact between the electrical components and the dura. Light from the diodes is reflected by blood in the dura and brain, received by the photodetector, and the resultant electrical siganls are processed by the pulse oximeter.
