Publication number: 20110152645Abstract: An adapter allows the interconnection of a sensor originating from one manufacturer to be coupled with conventionally incompatible monitors originating from other manufacturers to form a properly functioning pulse oximetry system. The adapter matches a sensor driver in a monitor to the current requirements and light source configuration of a sensor. The adapter also matches a sensor's light detector signal level to the dynamic range requirements of a monitor preamplifier. Further, the adapter provides compatible sensor calibration, sensor type and security information to a monitor. The adapter may have a self-contained power source or it may derive power from the monitor, allowing both passive and active adapter components. The adapter is particular suited as an adapter cable, replacing a conventional patient cable or sensor cable as the interconnection between a sensor to a monitor in a pulse oximetry system.Type: ApplicationFiled: November 29, 2010Publication date: June 23, 2011Inventors: Massi E.

Patent number: 6792300Abstract: An optical probe, which is particularly suited to reduce noise in measurements taken on an easily compressible material, such as a finger, a toe, a forehead, an earlobe, or a lip, measures characteristics of the material. A neonatal and adult disposable embodiment of the probe include adhesive coated surfaces to securely affix the probe onto the patient. In addition, the surface of the probe is specially constructed to minimize light piping effects. Furthermore, a flex circuit acts as a spring to absorb shock which may misalign the emitter and detector. One embodiment of the adult probe includes a cushioning pocket formed for a fingertip to align the probe and to absorb motion of the probe due to contact. The neonatal probe is formed with a unique V-configuration which provides multiple advantages.Type: GrantFiled: July 3, 2001Date of Patent: September 14, 2004Assignee: Masimo CorporationInventors: Mohamed Diab, Esmaiel Kiani-Azarbayjany, David R.

Publication number: 20030018243Abstract: A selectively plated low-noise optical sensor for non-invasive physiological monitoring has an LED emitter that emits light at a known wavelength. The light propagates through a body material and an attenuated signal is received by a photodetector, which produces an electrical signal indicative of the intensity of light energy incident on the detector. The electrical signal is conducted through a plurality of traces to a contact end of the sensor. The contact end allows connection to a connector which communicates the electrical signal to a processor. The emitter and detector are connected to the sensor traces at trace connection pads in the component connection areas. The trace connection pads in the contact area and the connection areas are electroplated with a protective metallic layer. The traces are otherwise covered with a solder mask.Type: ApplicationFiled: June 7, 2002Publication date: January 23, 2003Inventors: Thomas J. Gerhardt, Yassir Abdul-Hafiz, Eugene E. Mason, David R.

Patent number: 6285896Abstract: A sensor provides pulse oximetry measurements from the presenting portion of a fetus. In particular, a spiral probe is designed to attach the sensor to the fetal scalp. In one sensor configuration, a light emitting region of the probe embedded in the scalp in conjunction with a light detector located at the scalp surface measures absorption from a larger volume of the scalp tissue than conventional fetal sensors. In another sensor configuration, light emitting and light collecting regions of the probe embedded in the scalp are angled with respect to the scalp surface to measure absorption from a larger volume and deeper layers of the scalp tissue than conventional fetal sensors. These sensors increase the likelihood of measuring blood volume changes occurring in larger arterioles versus smaller arterioles or capillaries, yielding a representative measurement of central arterial oxygen saturation. These sensors also reduce the calibration errors caused by a low blood fraction.Type: GrantFiled: July 7, 1999Date of Patent: September 4, 2001Assignee: Masimo CorporationInventors: David R.
