摘要:
A device and method for performing blood coagulation assays, particularly prothrombin times and activated partial thromboplastin times and other clotting parameters are disclosed. The device comprises a disposable strip (containing a sample inlet for sample delivery, a capillary channel for driving force, and a reaction chamber with an appropriate dry reagent for a specific assay) and a piezoelectric sensor. The device could also include a heating element for temperature control, and a magnetic bender. The magnetic bender is driven by an electromagnetic field generator and is attached onto a piezoelectric film in contact with the blood sample. Electric signal generated at the piezo film is characterized by its frequency and amplitude due to the movement of the attached metal film. The signal collected at the site of the piezo film represents the process of a biochemical reaction in the reaction chamber, while blood sample proceeds to the point at which clot formation starts and is amplified by an amplifier and rectified into a Dc voltage and is sent to a recording unit and/or display unit.
摘要:
An infrared touch screen device that is externally adaptable to a video monitor for serving as an input device to a computer connected to the monitor. A bezel is adapted to be releasably secured over a viewing end of a video monitor. A plurality of infrared emitters are disposed along the bezel to form a grid of vertical and horizontal infrared beams in the interior space of the bezel when the emitters are activated. A plurality of infrared sensors are disposed along the bezel. Each sensor is optically aligned with an oppositely disposed one of the emitters. An activating circuit is mounted on the bezel for sequentially activating, in a predetermined sequence, respective ones of the emitters. A scanning circuit is mounted on the bezel for sequentially scanning the sensors in a sequence corresponding to the predetermined sequence, the sensors each producing output signals corresponding to the presence and absence, respectively of an infrared beam emitted by an oppositely disposed infrared emitter. A communication device couples the output signals of the sensors to an input port of a computer connected to the monitor.

A drinking bladder jacket apparatus for convenient beverage storage and drinking includes a jacket having a jacket body, a pair of sleeves coupled to the jacket body, and an inner lining. A bladder pocket is coupled to the inner lining. A bladder is coupled within the bladder pocket. The bladder has a fill port and a release port extending into a bladder inside that holds a beverage. A cap is selectively engageable with the fill port to seal or unseal the bladder inside. A drinking tube is coupled to the bladder and extends either through one of the sleeves of the jacket or through a hood portion of the jacket if present. A valve is coupled to the drinking tube to restrict or allow the flow of the beverage.

摘要:
A device and method are disclosed for determining whether or not an individual's blood coagulation time is in a normal or abnormal range, and is particularly suitable for measuring prothrombin time and activated partial thromboplastin time coagulation values. The device includes a housing with an area for receiving a sample, a capillary channel or elongated area with an absorbent material, and a gradient heater. Liquid crystal and a coagulation agent can be disposed within the device to mix with a sample added to the device. The mixture passes along the capillary channel or absorbent material and stops moving when the sample has clotted. Due to the gradient heater and liquid crystal, the mixture may or may not change color, depending upon whether the individual has a an abnormally short, normal, or abnormally long clot time.
