Patent number: 8469985Abstract: A puncture instrument includes a movable body movably disposed in a case, and a needle unit held by the movable body and having a needle. When a distal end face of the movable body is brought into abutment against a region to be punctured and the case is advanced toward the region to be punctured, the case is advanced together with the needle unit, and the tip end of the needle becomes protruded from the movable body and punctures the region to be punctured. An arm of the needle unit is abutted against and turned about a fulcrum member, thereby withdrawing the needle rearwardly.Type: GrantFiled: November 12, 2009Date of Patent: June 25, 2013Assignee: Terumo Kabushiki KaishaInventor: Daisuke Nishiuchi

Patent number: 8372105Abstract: A puncture instrument includes a needle assembly, a hub passage for axially guiding a hub, a needle passage communicating with the hub passage and having a distal end opening for allowing the tip end of a needle to project instantaneously therethrough, two arms having first junctions connected to the hub and inclined rearward in a direction away from the hub in an initial state, two push rods connected to second junctions of the arms and extending rearward, a button for pushing the push rods forwardly, and fulcrum members disposed more closely to the distal end than the arms for abutment against portions of the arms when the arms are moved. When the push rods are pushed forwardly by the button, the arms push the needle assembly forwardly, thereafter have portions thereof brought into abutment against the fulcrum members, and turn to pull the needle assembly rearward.Type: GrantFiled: August 22, 2008Date of Patent: February 12, 2013Assignee: Terumo Kabushiki KaishaInventors: Daisuke Nishiuchi, Takayuki Sugiyama

Patent number: 8147425Abstract: A centesis instrument, wherein a patient applies a contact part to a palm, a finger, or an arm in the state of gripping an outer tube by hand and presses the outer tube against its measured portion. A third coiled spring is compressed to increase spring power. When the outer tube reaches a prescribed position, the tip face of the vertical portion of a centesis button reaches a hole part, and a projected part is allowed to be pressed. When the patient presses a button body from a direction perpendicular to the axis of the button body by using a finger at that position, a locking piece is separated from a locking part and the centesis needle of a centesis needle unit is instantaneously projected from the opening part of the contact part to the measured portion by the spring power of the third coiled spring for centesis. Thus, a prescribed amount of blood can be taken out from the measured portion.Type: GrantFiled: March 20, 2006Date of Patent: April 3, 2012Assignee: Terumo Kabushiki KaishaInventors: Toshihisa Nakamura, Daisuke Nishiuchi, Yoshiaki Yaguchi, Masao Takinami
