Abstract: A myoelectric sensor for detecting myoelectric signals which accompany body movement includes: a wearing band that is elastic, expandable, and circular, and that is worn around a limb to surround the limb tightly; myoelectric detection units a plurality of which are disposed in the circumferential direction on the wearing band with intervals therebetween so as to cause each of a plurality of myoelectric detection electrodes to be in close contact with the surface of the limb, and which detect myoelectric signals from corresponding positions on the limb using the myoelectric detection electrodes; and connection cables that electrically connect mutually adjacent myoelectric detection units and thereby transmit the myoelectric signals. The connection cables each include a bent portion, the bent shape of which changes in response to changes in the distance between the mutually adjacent myoelectric detection units.

Abstract: A medical device made of an ester resin, such as a hollow-fiber-type blood treatment device, is put into a packaging material made of a gas-impermeable material, and, with at least a reducing gas, such as hydrogen gas, being further enclosed therein, the packaging material is hermetically sealed to provide a medical device package. The medical device package is exposed to radiation to sterilize the inside thereof. In the medical device package, an oxygen scavenger may be further enclosed. The reducing gas may be mixed with an inert gas and enclosed as a mixed gas. As a result, it becomes possible to effectively suppress the generation of by-products, such as acetic acid, from the ester resin.

Abstract: Provided is a guide wire having a novel structure, with which it is possible to improve production efficiency and to effectively prevent large irregularities from forming on an outer circumferential surface of a core wire. Further provided is a guide wire having a novel structure, with which it is possible to more meticulously set bending rigidity to a distal end portion thereof. In a guide wire having a coil externally mounted about a distal end portion of a core wire, a proximal end portion of the coil is integrally joined to the core wire during formation of the coil. Furthermore, in a guide wire having a coil externally mounted about a distal end portion of a core wire, a cross-sectional shape of a wire that constitutes the coil varies in a lengthwise direction of the coil.

Abstract: A fluid concentration measuring device measures the concentration of a fluid flowing through a duct having a light-transmissive, deformable duct wall. The device includes a light source; a light receiving element which receives the light, which passed through the wall of the duct and the fluid inside the duct, and outputs a signal indicating the intensity of the light; light path distance setting means and fluid concentration output means which obtains a plurality of relational expressions, which indicate the relation between the light intensity and the fluid concentration when the light from the light supply part is received by the light receiving part over each of the light path distances, and obtains the fluid concentration from the light intensity at the light receiving part based on the relational expressions for the plurality of light path distances and outputs the fluid concentration.
