Abstract: A catheter assembly includes: a catheter having a first lumen; a catheter hub joined to a proximal end of the catheter; a reinforcement needle inserted through the first lumen of the catheter, having a second lumen, and including a distal portion that is blunt; a reinforcement needle hub joined to a proximal end of the reinforcement needle; an inner needle inserted through the second lumen and including a sharp needle tip at a distal end thereof; an inner needle hub joined to a proximal end of the inner needle; a first fixing portion configured to fix the catheter hub and the reinforcement needle hub so as not to be detachable by an operation of pulling the catheter hub and the reinforcement needle hub in an axial direction; and a second fixing portion configured to fix the reinforcement needle hub and the inner needle hub to each other.

Abstract: A catheter fixing device includes a skin fixation part configured to come into contact with skin, a hub fixation part configured to retain a hub, and a movement mechanism provided between the skin fixation part and the hub fixation part and interlocking the hub fixation part with the skin fixation part such that the hub fixation part and the skin fixation part are movable relative to each other.

Abstract: A catheter assembly includes: an inner needle including, at a distal end portion of the inner needle, a blade surface that is inclined with respect to an axis of the inner needle; a needle hub fixed to a proximal end portion of the inner needle; a tubular catheter shaft through which the inner needle is inserted; a hollow catheter hub through which the inner needle is inserted and that is fixed to a proximal end portion of the catheter shaft; and a restriction mechanism configured to restrict relative axial movement of the catheter hub and the needle hub along an axial direction in an initial state of the catheter assembly. The restriction mechanism is configured such that the restriction of the relative axial movement is released when the needle hub is rotated with respect to the catheter hub along a circumferential direction of the inner needle from the initial state.

Abstract: A catheter system includes: a catheter assembly that includes: an inner needle having a needle tip at a distal end thereof, a hollow needle hub fixed to a proximal end section of the inner needle, a catheter shaft into which the inner needle is inserted, and a catheter hub having the inner needle inserted thereinto, wherein the catheter hub is fixed to a proximal end section of the catheter shaft; and a catheter gripper that is attachable to and detachable from the catheter assembly, wherein the catheter gripper includes: a gripping member, and an attaching/detaching mechanism configured to attach and detach a proximal end section of the needle hub to and from a first end section of the gripping member.

Abstract: A catheter includes: a first port; a second port; a first lumen communicating with the first port; a second lumen configured to selectively communicate with the first port and/or the second port; and a switching mechanism part selectively switchable between a first switching state in which the first port and the second lumen communicate with each other and a second switching state in which communication between the first port and the second lumen is blocked.

Abstract: A seat for vehicles including a seat cushion, a seat back, and a head rest has the following arrangement to ensure that a surface member can be relatively easily but positively removed from a urethane pad if a foam molding defect is found in the urethane pad in integral molding of the urethane pad and the surface member. In the seat for vehicles, any one of the seat cushion, seat back, and head rest has a configuration where a surface of the urethane pad is covered with the surface member. The urethane pad and the surface member are partially bonded together by integral molding.

Abstract: A structure of wadded-up seat trim cover, having a plurality of trim cover pieces sewn together at one end, each composed of a wadding member and a skin member, includes a bonded portion formed by bonding the skin member to the wadding member made shorter than the skin member, at a position remote, by a prescribed distance, from the end of the wadding member overlapping the skin member; a first sewn portion formed by bending that portion of the skin member, not overlapping the wadding member, along the end of the wadding member and then by sewing the portions of the adjacent skin members together; and second sewn portions formed by bending each end of the adjacent skin member to the back of the trim cover piece at the first sewn portion and then by sewing the adjacent skin members together at overlapping portions.

Abstract: A comfortable, well-designed vehicle seat (1) is provided by giving an outstanding, three-dimensional appearance to the surface layer of the vehicle seat so that a new design is achieved and that softness is improved. The vehicle seat has a seat cushion (2) serving as the sitting surface of the seat, a seatback (3) serving as the backrest of the seat, and a headrest (4) protecting the head and neck of an occupant. The surface of at least one of the seat cushion and the seatback is provided with a cover formed of a cloth including an upholstery material (6), a cushion material (8), and a heat-shrinkable material (9). The cover is stitched so that a plurality of bumps and dips are formed on the surface thereof.

Abstract: The present invention provides a vehicle seat with little fine creases on a concave portion of a seat surface even the use of natural leather such as a cowhide as a skin material for the vehicle seat. A vehicle seat includes a seat cushion making a seated portion of the seat; a seat back disposed at a back side of the seat cushion and making a backrest portion of the seat; and a cover formed of a cloth including a skin material, an adhesive material, and a cushion material at a concave portion on at least one surface among the seat cushion and the seat back. The cover is formed into a concave shape by heat presswork with a mold having a curved surface.

Abstract: The purpose of the present invention is to provide a vehicle seat provided with beads which bend easily in two dimensions in the plane in which outlet seam sections extend, are durable, and do not readily impart a sense of incongruity to people. This vehicle seat is provided with seat covers (2A, 3A, 4A) which cover the surface of a seat (1). The seat covers (2A, 3A, 4A) are provided with: a plurality of skin members (2A1-4A2); and beads (5A-5G) with which the plurality of skin members (2A1-4A2) are sewn together. The beads (5A-5G) are each formed from: a protrusion; and outlet seam sections which are provided to both sides of the protrusion, and which sew together the skin members (2A1-4A2). The beads (5A-5G) are formed from a woven fabric obtained by weaving fibers.
