20080319288 | Saccharide-measuring fluorescent monomer, saccharide-measuring fluorescent sensor substance, and implantable, saccharide-measuring sensor - A saccharide-measuring fluorescence sensor substance including a copolymer of at least the following two compounds (I) and (II) is provided: | 12-25-2008 |
20100331875 | PUNCTURE DEVICE - The present invention provides a puncture device and an administration device in which a puncture needle can be stuck certainly to a predetermined region of a skin. The puncture device and the administration device of the present invention are provided with a puncture needle moving means for retaining aforesaid puncture needle to be movable and a skin deforming means for deforming the skin, wherein it is constituted such that the puncture needle is moved by aforesaid puncture needle moving means and punctures the skin deformed by aforesaid skin deforming means. | 12-30-2010 |
20110015641 | BONE CEMENT INJECTING TOOL - A bone cement injecting tool is configured to be capable of inhibiting or preventing the occurrence of air bubbles in the liquid as a pressure transmitting medium. The bone cement injecting tool is composed of a first cylinder possessing a bore, a second cylinder possessing a bore, a first gasket slidably sealing the bore of the first cylinder, a second gasket slidably sealing the bore of the second cylinder, a tube communicating the first cylinder and the second cylinder, and liquid (e.g., water) filling the space I the tube and the first and second cylinders between the two gaskets. A piston is positioned in the first cylinder, and a pressure-retaining member applies pressure to the forward end of the piston so the piston moves the first gasket toward the forward end, thereby delivering the water to the second cylinder through the tube. During storage, the pressure-retaining member pushes the piston toward the fore-end, and this pushing force produces the pressure of the water. | 01-20-2011 |
20120253144 | SENSOR - An embeddable sensor includes a sensor body, a detector housed in the sensor body, and a retaining mechanism mounted on a side surface of the sensor body. The retaining mechanism includes at least one projection on the side surface of the sensor body. The projection is of a V shape which is progressively wider and higher from a distal end toward a proximal end of the sensor body. The projection is made of a material whose hardness is lowered upon elapse of a certain period of time within a living body. When the embeddable sensor is inserted in the living body, the projection retains the embeddable sensor within the living body. Upon elapse of the certain period of time within the living body, the projection loses its capability to retain the embeddable sensor within the living body. | 10-04-2012 |
20130037727 | FLUORESCENCE SENSOR - A fluorescence sensor includes a silicon substrate on which a PD element that converts fluorescence into an electric signal is formed, an LED substrate having a first principal plane on which an LED element that generates excitation light is formed, a reflective film that averages a light amount distribution of the excitation light radiated from a second principal plane of the LED substrate, and an indicator layer that receives the excitation light averaged by the reflective film and generates the fluorescence having a light amount corresponding to an analyte amount. | 02-14-2013 |
20130281802 | SENSOR SYSTEM, AND METHOD OF USING SENSOR SYSTEM - A sensor system and a sensor system using method improve operability of a placing operation of placing a sensor in a living body and improve user-friendliness of users. The sensor system has: a sensor member which has the sensor which detects analyte components of the living body and transmits a signal, and a retaining portion which retains the sensor; a needle assembly detachably attached to the sensor member and having a guide needle which guides insertion of the sensor to the living body; a signal processing circuit member detachably attached to the sensor member, and having an electronic circuit which processes the signal from the sensor; and a fixing member which fixes the sensor member to skin of the living body, and the sensor is placed in the living body in a state in which the signal processing circuit member is attached to the sensor member. | 10-24-2013 |
20140017799 | SENSING METHOD AND SENSING DEVICE - This invention relates to a sensing method and a sensing device for quantifying the concentration of an analyte by using the property that interaction between an analyte and a labeled compound changes fluorescence intensity. A fluorescence sensor is used to acquire fluorescence intensity at predetermined quantification time points. Then, the concentration of an analyte is quantified in accordance with a non-steady concentration quantification law comprising the relationship between the acquired fluorescence intensity and the time derivative quantity thereof. | 01-16-2014 |
20140349383 | FLUORESCENT SENSOR AND SENSOR SYSTEM - A fluorescent sensor includes a detecting substrate, an indicator, a filter layer, a light blocking layer, and an LED chip. In the detecting substrate, a PD element for converting fluorescence into electric signals is positioned on wall surfaces of a through-hole which penetrates a first main surface and a second main surface. The indicator is arranged inside the through-hole and generates fluorescence of intensity corresponding to analyte density when the indicator receives excitation light. The filter layer covers the PD element, transmits fluorescence and blocks excitation light. The light blocking layer, through which an analyte can pass, covers an opening of the first main surface of the through-hole. The LED chip covers a region just below an opening of the second main surface of the through-hole, and generates excitation light. | 11-27-2014 |
