Abstract: An optical probe, which is particularly suited to for use in measurements on tissue material of a patient. In one embodiment, the probe comprises upper and lower housing elements incorporating a light energy source and corresponding detector. The tissue material of the patient is disposed between the upper and lower housing elements such that the light energy emitted by the source passes through the tissue material to the detector. A plurality of light shields are attached to one or both of the housing elements to reduce the amount of ambient and reflected light reaching the detector. Additionally, various portions of the upper and lower housing elements and shields utilize light absorbent coloration and/or coatings which further mitigate the effects of undesired ambient and reflected light, thereby reducing noise generated within the instrument and increasing its accuracy. In one embodiment, the light shields are made removable from the optical probe, thereby facilitating replacement.

Abstract: 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.

Abstract: An electrical connector is disclosed which provides connection of sensors to monitors. The connector is designed to be low-profile, permit ease of attachment and disconnection, and maintain a strong connection to prevent accidental disconnects.

Abstract: A cursory inspection of the device reveals a small "Funnel" but because the funnel (or device) is plugged at the base (or bottom) the name "Funny Funnel" was developed. Unlike a true funnel, the back is flat and higher than the rounded front. The highly visible area on the inside of back will be referred to as the "area of promotion," which may be used for advertising, logos, etc. Vehicle use requires a Velcro.RTM. "button" for support while home or industrial use requires a supportive base. In both instances the "funnel" can be easily removed for cleaning, etc. A burning cigarette is easily deposited because of the large opening at the top. The cigarette will extinguish itself in seconds and can be relit. The "funnel" shape of the device, the use of the Velcro.RTM. button and the "area of promotion" are new a new concept for cigarette extinguishers.
