Patent CA-2079192-C (CA)
Title: Combined lancet and multi-function cap and lancet injector for use therewith
Inventor: STRONG BERNARD
IPC: A61B5/15
Filed: 1992-09-25
Granted: 1995-12-26
Abstract: A combined lancet and multi-function cap of the disposable type, for use in obtaining blood samples for diagnostic purposes. It comprises a lancet including a needle with a sharp end, and an elongated body of plastic material embedding the needle except for its sharp end. It also comprises a multi-function cap also made of plastic material, which is detachably mounted onto one end of the body to embed the sharp end and keep it sterile until the lancet is used. The multi-function cap includes a ring having a central opening sized to let pass the sharp end of the needle but not the body of the lancet. The multi-function cap also includes a set of legs or a skirt that project from the ring and are useful for connecting the same to a lancet injector having a mouth through which the lancetmay be inserted and suhsequently projected out to penetrate the skin of a patient. Thus, the cap also serves as an isolation barrier between the patient's finger and the physical lancet injector. In use, when the multi-function cap is detached from the lancet and is connected to the lancet injector, the ring of the cap extends across the mouth and positively controls the depth of penetration of the lancet in the patient's skin. This ring also serves to lock the needle within the cap after use and thus reduces the danger of accidental finger-stick by a blood contaminated needle. Also disclosed is a lancet injector for use with the above lancet and multi-function cap, which is so devised as to eject the lancet after use, together with the cap that firmly grips onto the lancet to act as a protective locking hood for the needle. This lancet injector preferably incorporates an elastomeric band to project the lancet upon firing, instead of a metallic coil or leaf spring.
Patent CA-2085914-C (CA)
Inventor: BRAIN ARCHIBALD I J
IPC: A61M16/04
Filed: 1992-12-21
Granted: 1995-10-31
Abstract: A laryngeal mask has an inflatable ring configured, upon inflation, to establish a peripheral seal around a patient's laryngeal inlet.  Installation (insertion) is made in the fully deflated state, wherein the structural relation between the body of the mask and the inflatable ring is such that deflated ring surfaces become tightly opposed to each other so as to form a thin flange which peripherally surrounds the body of the mask and is concave on the posterior side of the mask; the concave flange effectively displaces all ring material away from the aperture of the mask, in the manner of the upturned brim of a hat.  The concave flange is softly yieldable in its confinement by local body structures encountered in the course of mask insertion.  And it is an important feature that the distal end of the deflated ring is adapted not only to smoothly ride posterior contours of the throat and pharynx but also to gently cam the epiglottis out of the path of insertial displacement of the mask while also assuring that the distal end of the deflated mask smoothly enters the upper sphinctral region of the oesophagus.  Once thus insertionally located, ring inflation will assuredly establish the desired peripheral seal of the mask around the laryngeal inlet.

Filed: 1991-09-10
Granted: 1997-02-18
Abstract: An echo cancelling device (15) for reducing acoustic feedback between a loudspeaker (32) and microphone (10) in a full duplex, system such as a telephone conferencing system. A whitening filter (14) flattens the microphone signal's spectrum and reduces its auto-correlation. A signal splitter (16) separates the whitened microphone signal into a plurality of ban-dlimited microphone signals. The loudspeaker signal is similarly whitened and separated into a plurality of bandlimited loud-speaker signals by a signal splitter (30). Each of a plurality of echo cancellers (18) generates an echo estimation signal represen-ting an approximation of the acoustic feedback of a corresponding bandlimited loudspeaker signal into the microphone. The echo canceller (18) removes each echo estimation signal from the bandlimited microphone signal of the same frequency band as the estimation signal. Center clippers (20) remove any residual echo in each echo corrected signal. Noise fillers (22) simulate the background signals removed by the dippers (20).
