Patent number: 11369412Abstract: A sensor insertion device comprises a main body, needle slider, disposal slider, spring, puncture knob, and opening mechanism (window member and handle). The needle slider grips a needle and a sensor on a first end side, and is slidable inside the main body. The disposal slider is slidable inside the main body. The puncture knob has an insertion hole into which the rear end portion of the needle slider can be inserted. The opening mechanism puts the insertion hole into a closed state when the needle slider is being slid in the sensor insertion direction, and, puts the insertion hole in an open state in which the second end side of the needle slider has been inserted into the insertion hole by opening up the contact portion between the puncture knob and the second end side of the needle slider when the puncture operation is complete.Type: GrantFiled: April 7, 2017Date of Patent: June 28, 2022Assignee: PHC HOLDINGS CORPORATIONInventors: Yoshiteru Ii, Kenichi Hamanaka, Ryuji Shimizu, Akira Nishio, Takashi Endoh, Kazuaki Edagawa, Tetsuya Norikane, Junko Ikeda

Publication number: 20140200635Abstract: Provided is a phototherapy device which enables a sufficient amount of light to reach a deep tissue to achieve a satisfactory therapy while preventing the increase in the skin temperature of an affected part, and which can achieve a comfortable therapy. The present invention provides a phototherapy device comprising a sheet-like member having a first surface on which an affected part is to be arranged and a surface light source for emitting light toward the sheet-like member, wherein the first surface is formed in an uneven shape so as to provide multiple grooves. The phototherapy device can be used for, for example, the treatment of an affected part in a rheumatoid arthritis patient.Type: ApplicationFiled: August 20, 2012Publication date: July 17, 2014Applicant: PANASONIC CORPORATIONInventors: Yoshiteru II, Yuki Kawase, Daisuke Okamura, Shuhei Tanaka

Publication number: 20120316623Abstract: Disclosed is a phototherapy device which can irradiate an affected part, which is to be irradiated with light, with light selectively and intensively and can prevent eyes to undergo the direct irradiation with intense light emitted from a light source. Specifically disclosed is a phototherapy device comprising: a light guide member which has a contact surface that contacts with an affected part and an opposed surface that faces the contact surface and which serves as a light guide path; and a first light source which can emit light having the main wavelength that depends on the wavelength range of infrared ray to the light guide path. In the phototherapy device, a material constituting the light guide member has a refractive index identical to or higher than the refractive index of a biological tissue.Type: ApplicationFiled: January 28, 2011Publication date: December 13, 2012Applicant: PANASONIC CORPORATIONInventors: Yoshiteru Ii, Takuo Shimada, Jiro Minehisa, Yuki Kawase
