Publication number: 20190381253Abstract: An administration instrument includes an injection button which can be pressed at an angle that is not parallel to a needle with respect to a direction in which the needle is inserted into skin. As a result, it is possible to prevent a force of pressing the injection button from being transmitted in the direction in which the needle is inserted into the skin deeper than initial insertion of the needle, thereby achieving an administration under a stable state.Type: ApplicationFiled: August 29, 2019Publication date: December 19, 2019Inventors: Tokumi BABA, Tokumi ISHIKAWA, Kouichi MATSUDA

Patent number: 8974413Abstract: The present invention relates to an administration instrument for medical use that can perform injection of a drug solution with stability and with great reliability. For example, at the administration, it is possible to prevent a force that presses the injection button from acting in a direction of inserting the needle that is inserted into the skin deeper, and enables the administration under a stable state where the needle does not wobble, thereby alleviating physical and mental pain of the administration patient. With a structure in which an injection button (3) is pressed at an angle that is not parallel to the needle with respect to a direction in which the needle (4) is inserted into the skin, it is possible to prevent the force of pressing the injection button from being transmitted in a direction of inserting the needle into the skin deeper than the initial insertion of the needle, thereby achieving an administration under a stable state.Type: GrantFiled: October 14, 2010Date of Patent: March 10, 2015Assignee: Panasonic Healthcare Co., Ltd.Inventors: Tokumi Baba, Tokumi Ishikawa, Kouichi Matsuda
