Patent number: 11141194Abstract: The uterine hemostatic balloon unit includes a tube, a hemostatic balloon, a connector disposed in the tube, and a cap to be detachably attached to a proximal end portion of the tube. The tube has a drain channel for draining uterine blood outward and a water supply channel communicating with the hemostatic balloon. The connector has a drain terminal communicating with the drain channel and disposed in a proximal end portion of the tube, a flexible water supply tube communicating with the water supply channel and extending by being bifurcated outward of the tube, and a water supply terminal communicating with the water supply tube. The cap has an accommodating portion capable of accommodating the water supply terminal along a length direction of the drain terminal. The accommodating portion is open in a direction orthogonal to the length direction of the drain terminal.Type: GrantFiled: June 12, 2019Date of Patent: October 12, 2021Assignee: ATOM MEDICAL CORPORATIONInventors: Keisuke Wakabayashi, Shinichi Kobayashi, Tatsuhiko Seki, Ichiro Matsubara

Publication number: 20210186561Abstract: Provided is a balloon unit for uterine hemostasis capable of reliably suppressing or stopping uterine bleeding. The balloon unit includes a flexible tube and a balloon provided in a distal end portion of the tube. The balloon has a lower uterine lumen compression portion that compresses an inner surface of a lower uterine lumen and an upper uterine lumen compression portion that compresses an inner surface of an upper uterine lumen. As the balloon, two balloons including a first balloon functioning as the lower uterine lumen compression portion and a second balloon functioning as the upper uterine lumen compression portion are provided.Type: ApplicationFiled: September 5, 2019Publication date: June 24, 2021Inventors: Eiji Kondoh, Keisuke Wakabayashi, Ryoko Kakinuma, Shinichi Kobayashi, Tatsuhiko Seki, Ichiro Matsubara

Patent number: 7153290Abstract: A flange attaching section has a flange supporting section and a movable section, and the movable section can approach the flange supporting section and separate therefrom due to rotational moving. Even if a flange section of a barrel of a syringe has various thickness, the flange section is easily attached between the flange supporting section and the movable section, and although the attachment is easy, the flange section comes in pressure contact with the flange supporting section in the attached state. Even if, therefore, the flange section of the barrel of the syringe has various thickness, a syringe pump, in which moving of the barrel of the syringe during infusion is prevented securely and the infusion is executed at an accurate speed, is provided.Type: GrantFiled: July 30, 2003Date of Patent: December 26, 2006Assignee: Atom Medical CorporationInventors: Keisuke Wakabayashi, Tatsuhiko Seki, Kazuo Matsubara

Patent number: 6592511Abstract: In this incubator, the door rotation restricting means in the operating state restrains the rotation of the door in the opening direction beyond the operating angle. Thus, in the case that the door rotation restricting means is in the operating state, even if the door is pushed by the accommodated baby from the inside of the hood under the state wherein the door is not fixed by the door fixing means in a closing state, the door does not rotate in the opening direction beyond the operating angle and the angle of the door does not exceed the operating angle. Therefore, even if opening and closing operation of the nursing window is not securely performed, at least the environment inside the hood hardly deviates from the physiological environment appropriate for the accommodated baby.Type: GrantFiled: July 11, 2001Date of Patent: July 15, 2003Assignee: Atom Medical CorporationInventors: Naoki Honma, Yoichi Takahashi, Tatsuhiko Seki, Kazuo Matubara

Patent number: 6484670Abstract: In this incubator, when the angle of a door to a nursing window of a hood is smaller than a rotation restricting angle, door rotation restricting means restrains the rotation of the door in an opening direction. Because of this reason, when the angle of the door is smaller than the rotation restricting angle, the door is not rotated in the opening direction beyond the rotation restricting angle and the angle of the door does not exceed the rotation restricting angle, even if the door is pushed by an accommodated baby from the inside of the hood under the state wherein the door is not fixed in the closing state by a door fixing device. Therefore, even if opening and closing operation for the nursing window is not securely performed, the environment inside the hood hardly deviates from the physiological environment appropriate for the accommodated baby to say the least.Type: GrantFiled: July 11, 2001Date of Patent: November 26, 2002Assignee: Atom Medical CorporationInventors: Naoki Honma, Yoichi Takahashi, Tatsuhiko Seki, Kazuo Matubara
