摘要:
An analyte monitor includes a sensor, a sensor control unit, and a display unit. The sensor control unit typically has a housing adapted for placement on skin and is adapted to receive a portion of an electrochemical sensor. The sensor control unit also includes two or more conductive contacts disposed on the housing and configured for coupling to two or more contact pads on the sensor. A transmitter is disposed in the housing and coupled to the plurality of conductive contacts for transmitting data obtained using the sensor. The display unit has a receiver for receiving data transmitted by the transmitter of the sensor control unit and a display coupled to the receiver for displaying an indication of a level of an analyte, such as blood glucose. An inserter having a retractable introducer is provided for subcutaneously implanting the sensor in a predictable and reliable fashion.

摘要:
A medical lancing device including a replaceable multi-lancet cartridge. The lancing device includes an advancing mechanism that advances lancets within the cartridge into an active position, separates a protective cap from the active lancet, and energize a drive mechanism of the lancing device. A cap displacement mechanism moves the separated cap out of the travel path of the active lancet. In a first example embodiment, the cap displacement mechanism includes a cantilevered spring arm that displaces the detached cap of the active lancet. In a second example embodiment, the cap displacement mechanism includes a spring-biased cam-driven plunger that displaces the detached cap of the active lancet. Then an activation mechanism releases the energized active lancet to traverse the unobstructed lancing stroke path to pierce the subject's skin at a desired lancing site.

摘要:
A lancing device and a removable and replaceable multi-lancet cartridge for use in connection therewith are disclosed. The multi-lancet cartridge is advanced through sequential lancets, and anti-reverse features prevent reverse advancement of the cartridge. Interlocks are provided to prevent double-cocking the device, to reduce the likelihood of jamming of the mechanism. Improved trigger mechanisms and depth control mechanisms are provided.

摘要:
A lancing device and replaceable multi-lancet cartridge for use in sampling of body fluids. Sequential lancets of the cartridge are translationally retracted along a storage path, pivoted into an angularly offset firing path, and translationally propelled by a drive mechanism to lance the subject's skin.
摘要:
A sampling device having a lancing apparatus, and optionally a detector and a meter. The lancing apparatus includes a replaceable cartridge of lancets, each lancet having an independent arming and drive mechanism enabling non-sequential and/or simultaneous firing of lancets. A lancet retainer independently associated with each lancet is movable to uncover an opening through which the lancet tip passes, and to release the lancet for activation. The lancets can be actuated in any order, and multiple lancets can be simultaneously actuated, if desired.
摘要:
A CPR face mask has a substantially toroidal face engaging part positionable on the face of a patient to surround at least the mouth of the patient. A flexible generally conical part having a lower end extending around and is secured to an upper surface of the face engaging part, and an upper end with an aperture through which a CPR giving person can blow air which passes downwardly through the conical part and the toroidal part into the patient's mouth. The flexible generally conical part has a relatively short outwardly extending substantially horizontal portion at the lower end extending around and secured to the upper surface of the face engaging part, a relatively short portion extending upwardly and outwardly from an inner edge of the substantially horizontal portion, a relatively high frusto-conical portion extending upwardly and inwardly from an upper edge of the upwardly and outwardly inclined portion, a relatively short portion extending inwardly and downwardly from an upper edge of the frusto-conical portion and a central cylindrical portion extending upwardly from an inner edge of the inwardly and downwardly extending portion and providing said aperture. The mask can be positioned in a collapsed configuration for storage by downward movement of the central cylindrical portion to cause the frusto-conical portion to fold downwardly and extend into the toroidal face engaging part and can be returned to a ready-to-use configuration by an upward pull on the central cylindrical portion.
摘要:
A filter for use with a waveguide which is part of a low-noise block (LNB) for use with VSAT, satellite communications systems is described. The filter is cast into the waveguide wall at the same time as the waveguide is manufactured providing a waveguide filter with a consistent filtering performance.
