Publication number: 20230293842Abstract: A nasal adapter includes a first portion and a second portion. The first portion includes a mouth exhalation guide portion having a facing portion facing a mouth of a living body and formed with a mouth-side guide path for guiding exhaled breath exhaled from the mouth to the facing portion, a base portion disposed above the mouth exhalation guide portion with respect to the living body, and a cuttable portion integrally formed with the mouth exhalation guide portion and the base portion. The cuttable portion disconnectably connects the mouth exhalation guide portion to the base portion. The base portion is fixed to the second portion. The first portion is detachably connected to the second portion at a connecting section below the cuttable portion with respect to the living body.Type: ApplicationFiled: March 8, 2023Publication date: September 21, 2023Inventors: Takayuki AOYAGI, Toshiki AOKI, Kenichiro KABUMOTO, Fumihiko TAKATORI, Yuya BABA

Patent number: 11717632Abstract: An airway adaptor includes: a nasal expiration collecting portion which is to be connected to a nostril of a living body, and which collects an expiration of the nasal cavity; a gas passage portion that forms a gas passage through which the expiration collected by the nasal expiration collecting portion passes; and a gas sensor attaching portion to which a gas sensor that is disposed in the gas passage portion, and that measures the concentration of a predetermined gas component contained in the expiration is attachable. The nasal expiration collecting portion shows a flowing state where a flow of the expiration is allowed, and an obstruction state where the flow of the expiration is blocked.Type: GrantFiled: March 13, 2019Date of Patent: August 8, 2023Assignee: NIHON KOHDEN CORPORATIONInventors: Kenichiro Kabumoto, Takayuki Aoyagi, Fumihiko Takatori, Masayuki Inoue

Publication number: 20220257142Abstract: An airway adapter forms a part of a breathing circuit that is connected to a test subject. A first cylindrical portion forms a male terminal that is fitted into a female member forming another part of the breathing circuit. A second cylindrical portion forms a female terminal that compartmentalizes a fitting portion into which a male member forming another part of the breathing circuit is fitted. An airway forming portion is disposed in an internal space compartmentalized by the first cylindrical portion, and forms an airway communicating with the fitting portion. A first sealing member is disposed on an outer circumferential surface of the first cylindrical portion and has higher flexibility than the first cylindrical portion.Type: ApplicationFiled: February 7, 2022Publication date: August 18, 2022Inventors: Fumihiko TAKATORI, Yuya BABA, Kenichiro KABUMOTO, Takayuki AOYAGI, Kentaro SUZUKI

Publication number: 20220031981Abstract: A nasal adaptor includes: an oral expiration guiding portion which has an opposing portion that is to be opposed to the mouth of a living body, and in which a mouth-side guide path that guides expiration that is expired from the mouth to the opposing portion is formed; and an attaching portion which is placed above the oral expiration guiding portion with respect to the living body, and to which a holding member that holds a sensor for measuring the expiration guided by the oral expiration guiding portion is attached. The oral expiration guiding portion is integrally connected to the attaching portion, and has positioning changing portions that change the distances between connecting portions connected to the attaching portion, and the opposing portion, thereby changing the positioning of the opposing portion.Type: ApplicationFiled: November 14, 2019Publication date: February 3, 2022Inventors: Takayuki AOYAGI, Kenichiro KABUMOTO, Fumihiko TAKATORI, Masayuki INOUE

Patent number: 10912912Abstract: A gas measurement adapter includes a flow tube portion configured to allow gas to pass through the flow tube portion, and a window portion configured to allow measurement light for measuring a component of the gas passing through the flow tube portion to pass through the window portion. The window portion is thinner than the flow tube portion and is molded integrally with the flow tube portion. The window portion comprises an effective portion configured to allow the measurement light to pass through the effective portion and an outer peripheral portion provided on an outer periphery of the effective portion. An inner surface of the window portion is configured such that an outer perimeter of the effective portion is contiguously coplanar with the outer peripheral portion.Type: GrantFiled: September 27, 2018Date of Patent: February 9, 2021Assignee: NIHON KOHDEN CORPORATIONInventors: Yuya Baba, Masayuki Inoue, Hidetoshi Dainobu, Kenichiro Kabumoto, Fumihiko Takatori, Takayuki Aoyagi

Patent number: 7387681Abstract: A method of dispensing a liquid, which handles a minimum amount of liquid without wasting it and to dispense and spray an exact amount of the liquid without precipitating solid particles. The method including the steps of regulating a flow rate of liquid in a flow passage by orifices 8-1, 8-2 while letting the liquid flow through flow passages 10-1 and 10-2 between syringes 5-1 and 5-2 by applying a pressure of 0.001 MPa to 10 MPa to liquid 6 including solid particles and filled in one syringe vessel 5-1 and by setting a pressure of liquid in the other syringe 5-2 at a lower level than the pressure of liquid in the syringe 5-1 and dispensing the liquid from the flow passage by an auto dispensing valve 1.Type: GrantFiled: March 27, 2003Date of Patent: June 17, 2008Assignee: Nordson CorporationInventors: Masafumi Matsunaga, Takayuki Aoyagi, Kouki Terao
