20100241032 | METHOD OF STOPPING A BLEEDING FROM A FISTULA USING A TOURNIQUET DEVICE - A method of stopping a bleeding from a fistula situated on a limb of a patient for hemodialysis, includes: providing a tourniquet band having a blood-stopping protrusion projecting therefrom; encircling the limb of the patient with the tourniquet band to cover the fistula and pressing the fistula with the blood-stopping protrusion to stop the bleeding; connecting a sensor to the tourniquet band to sense a blood flow in the fistula and to generate a signal representative of the blood flow; and electrically connecting a notifying device to the sensor and using the notifying device to produce a notifying signal in response to the signal transmitted by the sensor. | 09-23-2010 |
20110057551 | HEAT DISSIPATING DEVICE FOR LIGHTINGS - A heat dissipating device for lightings includes a light source module, a heat sink, and a converter. The heat sink has a substrate and a plurality of heat dissipating fins extending outward from the substrate. A plurality of channels is formed between the heat dissipating fins. Insides of the channels respectively have a port open to the centre of the heat sink. Thereby, the channels of the heat sink can effectively direct the airflow into the centre of the heat sink, enhancing the heat dissipating effect of the heat sink. | 03-10-2011 |
