Patent number: 11571588Abstract: An object of the present invention is to provide a chair-type phototherapy device that enables a patient to perform light irradiation accurately targeted at a treatment site in a seated position on a chair and consequently achieves effective phototherapy even when the treatment site is in the back region that the patient is unable to see, for example, as in light irradiation for dysuria patients and patients with pain, and the patient performs light irradiation by himself/herself at home. The present invention provides a chair-type phototherapy device having a seat on which a patient is seated. The chair-type phototherapy device includes a radiation module configured to emit radiation light toward a living body, a drive module positioned behind the patient for moving the radiation module, and a fixing module fixing the drive module to the seat.Type: GrantFiled: June 27, 2019Date of Patent: February 7, 2023Assignee: Teijin Pharma LimitedInventors: Naoya Ishibashi, Yuki Kawase, Takuya Nanjo, Takamitsu Okayama

Publication number: 20160015588Abstract: Provided is an inexpensive device capable of accurately positioning a medical instrument relative to the head of a user. A head positioning device (7) is used. The head positioning device (7) is provided with: a pair of holding members (11, 12) which holds the face of a user from both sides by elasticity and prevents both the forward tilting of the user's head and the rotation of the neck; a neck rest (13) which comes into contact with the back side of the user's neck and determines the position of the neck in the front-rear direction; and a head-back rest (14) which comes into contact with the back of the head and which prevents the head from tilting backward.Type: ApplicationFiled: March 28, 2014Publication date: January 21, 2016Applicant: Teijin Pharma LimitedInventors: Rei TAMIYA, Takamitsu OKAYAMA, Kenji TOJO, Jun MATSUI

Patent number: 8881731Abstract: A respiratory mask system is provided, in which while wearing a respiratory mask system, force generated by movement of a user's head and the like to induce laterally slipping a mask cushion may be reduced or absorbed. The respiratory mask system is provided with a mask cushion covering a nose, a nose and a mouth, or a full face. A first frame is connected with the mask cushion to supply respiratory gas under positive pressure. A second frame is connected with a headgear strap, in which the mask cushion is placed on a face side of the first frame and the first frame is placed on a face side of the second frame. The first frame is connected slidably with the second frame along a slide surface.Type: GrantFiled: October 18, 2007Date of Patent: November 11, 2014Assignee: Teijin Pharma LimitedInventors: Masahide Takishita, Takamitsu Okayama, Keiko Omura, Tongoh Chin

Publication number: 20090014008Abstract: According to the present invention, there is provided a nasal respiratory mask contacting with the face of a user for supplying respiratory positive-pressure gas to the nose of the user, comprising at least a part attached tightly to the face that is attached tightly to the face of the user; a frame-fitting part for fitting to a frame; and an elastic connecting part that connects elastically the part attached tightly to the face with the frame-fitting part, wherein a facial side of the elastic connecting part is kept apart from the frame-fitting part side thereof for a required distance even in the absence of applied respiratory positive pressure. The nasal respiratory mask has advantages that it can be worn in an appropriate position without applying positive pressure at the start of wearing, scarcely disturbs the visual field during wearing, and can prevent prolongation of the time required for drying or occurrence of unsanitary condition after routine cleaning by washing with water.Type: ApplicationFiled: March 23, 2007Publication date: January 15, 2009Applicant: Teijin Pharma LimitedInventors: Masahide Takishita, Keiko Omura, Tongoh Chin, Takamitsu Okayama, Hideharu Shimura, Shinya Fujimoto, Toru Hikosaka, Satoe Matsunaga
