Abstract: A blood extraction device (100) and method for withdrawing a controlled number of drops of blood from a patient, in whom there is created an incision of such dimension that blood does not freely flow therefrom. A release unit (160) urges drops of blood to flow from the incision, for example by applying a vacuum, and a disabling unit (145, 146, 170) is coupled to the incision unit for disabling the release unit when a predetermined number of drops of blood have been withdrawn.

Abstract: An electrode assembly (10) for a portable ECG signaling device, comprises a thin, flexible electrode support (11) supporting thereon a plurality of electrodes in spaced relationship. The electrodes (V1, V2, V3, V4, V5 and V6, LA, RA, LL) are configured for producing a twelve-lead electrocardiogram, and the electrode assembly is foldable into a compact assembly when not in use.

Abstract: A portable ECG signaling device (12), comprising a housing (15) supporting a plurality of chest and limb electrodes (16, 17, 18, 19) for affixing to different parts of a patient's body (10) so as to measure the patient's rhythm strip and 12-lead ECG. An ECG signaling circuit (65) within the housing is adapted to collect and transmit in real time fractional ECG data on at least two output channels in parallel, thereby allowing complete ECG data to be transmitted in less time than could be done by collecting and transmitting the complete ECG data serially on a single output channel in real time. The ECG signaling circuit is preferably adapted to transmit on a first output channel the rhythm strip measured with two of the electrodes, and transmit on at least second and third output channels respective samples or functions thereof measured by predetermined ones of the chest and limb electrodes.

Abstract: An emergency signaling or diagnostic device (10), particularly with an ECG signaling device (11, 11′) embedded within a wallet (35) for signaling a health condition of an owner of the device. The wallet (35) may have embedded therein functions (40) of a cellular telephone and may include a vocalizing unit (16) for producing an acoustic signal representative of the owner's ECG.

Abstract: A pair of spectacles has a pair of channels formed in the frame and receiving respective temples which can be retracted and swung into a position in which they lie transverse to the frame to bring them into the position of use. The bar forming the frame member is curved to conform to the head of the wearer at the brow and the temples are of high flexibility so that they can conform to the curvature of the channels in the bar as well as to the head of the wearer. In additon, the ends of the bar are provided with detents for retaining the temples in respective inwardly swung or use positions.

Abstract: An easily assembled bed structure adjustable in length and width comprises head and foot members each including a pair of side posts and parallel slidably telescoping multielement tubular cross pieces extending laterally between and separably joined at their ends to respective side posts, a pair of parallel, longitudinally extending side beams each including slidably telescoping tubular elements and separably coupled at their ends to respective posts and longitudinally spaced parallel stringers each including slidably telescoping tubular elements and separably coupled at their ends to opposite respective beams or a third longitudinally adjustable beam intermediate and parallel to the side beams extends between and is joined to the lowermost of the head and foot member cross pieces or bracket members project inwardly from the side beams for supporting a mattress. Foot pieces depend from the stringers or third beam. The components of the structure are secured in their assembled condition by separable fasteners.
