摘要:
A gage mechanism for a blood pressure measuring device or other similar apparatus includes a supported shaft member having one end in contact with an inflatable bellows. A pointer is attached at an opposite end of the shaft and a helically wound spring is attached to the shaft and a supporting structure. As the bellows inflates, the shaft is axially displaced and causes rotation due to the constraint of the helical ribbon spring, causing a corresponding angular deflection of the attached pointer relative to an indicating scale. The mechanism includes a first adjustment member for allowing the pointer to be preset to a zero or calibrated position, and a second adjustment mechanism that controls the amount of angular rotation of the shaft and pointer for a displacement of the bellows.

A laryngeal blade assembly includes a light pipe assembly attached to a blade having a light pipe disposed along a major dimension of the blade. The light pipe assembly is releasably attached to the blade in a non-axial direction in relation to the major dimension, wherein said light pipe assembly can be released from the blade without the aid of tools. The light pipe assembly includes a supporting block for fixedly retaining the light pipe. The supporting block has a bore disposed in a non-axial direction to the major dimension of the blade. A non-axial member fixedly attached to the blade and sized for engaging the bore includes an undercut portion. An annular engagement member is fitted within said undercut portion for engaging the bore to allow the release of the light pipe assembly when a predetermined holding force is exceeded.

A pressure measuring apparatus includes a gage that is at least partially imbedded within a flexible elastomeric member disposed within an interior cavity of a device housing. A shock resistant member into which the gage is inserted permits fluid interconnection between the interior of the gage having a contained movement mechanism that is responsive to fluid pressure changes and a fluid source, such as an inflatable blood pressure cuff and further provides shock and/or impact resistance for a contained movement mechanism. Additional impact/shock absorption is provided by exterior features of the apparatus, including a peripheral bumper having a plurality of raised spring-like protrusions, and rubberized and contoured features of the device housing.

An LED for use with a medical diagnostic instrument having an adapter disposed between an instrument head and a hand-grippable handle, the LED being removably attachable in relation to the adapter in order to permit selective replacement of the LED, as needed. The LED is situated in order to provide mechanical and electrical interface with at least one of the adapter and the instrument, thereby enabling the adapter and the LED to convert the illumination source of the instrument selectively between an incandescent light source and the LED. The adapter matches a polarity between the LED and a power supply that is specifically intended for powering an incandescent light source.

A capacitive sensor is disclosed that includes a variable capacitor transducer that varies its capacitance with changes in an environmental parameter. The present invention is adapted to measure any linear parameter such as pressure, force, or distance. The sensor of the present invention is compact, inexpensive to make, and easily fabricated using commonly available components. Furthermore, it is not susceptible to errors caused by vibration, acceleration, and its orientation to the earth's gravitational field. The output of the capacitive sensor does not substantially drift with changes in temperature.
