  • Patent number: 9418574
    Abstract: A surgical operation training device 13 comprises a simulation body 83 subjected to a predetermined treatment during surgical operation training, a holder 84 for holding the simulation body 83 from below, a support 85 for supporting the holder 84 workably, a wire 86 for coupling the holder 84 with the support 85, and a control unit 71 for controlling operation of the holder 84. The wire 86 is formed of a shape memory material which can contract from an original shape when a current flows through the wire. The control unit 71 comprises a drive signal generating means 114 for supplying a current to the wire 86 at a predetermined timing and for performing operation control on the holder 84 with a change in the shape of the wire 86 by varying the supply state of current to the wire 86.

  • Patent number: 9039664
    Abstract: In a prefilled syringe including an elastic seal member to be pierced with a needle for use to eject a protein pharmaceutical preparation therefrom, the elastic seal member ensures smooth and reliable piercing thereof with the needle while reliably preventing an active substance of the protein pharmaceutical preparation from being adsorbed thereon. When a protective film (3) is laminated to a top surface of a seal body (2) of an elastic material, the protective film (3) is stretched to a greater extent by a recess (4) provided in the top surface. Further, the piercing portion to be pierced with the needle is provided in a bottom of the recess (4). Thus, the protective film (3) is formed as locally having a smaller thickness in the piercing portion.

  • Patent number: 8074427
    Abstract: A method and an apparatus for producing a container packing filler are provided, which ensure that a net can be correctly and speedily rolled up into a bulk or ball shape. A stretchable tubular net (N) is fitted around a columnar support member (6). Then, a distal portion of the net is forcibly folded radially outward or inward by a plurality of roller belts (30) disposed circumferentially of the net (N), while the roller belts (30) are moved toward a net proximal side axially of the net (N), whereby the net (N) is rolled up radially outward or inward with the distal portion thereof being forcibly folded by circular rotation and axial movement of the roller belts (30) to form an annular roll portion (C).

  • Patent number: 7971753
    Abstract: A filter-equipped container which, particularly in a small-sized eyedrop bottle or the like, is capable of accurate dropping while preventing bubbles from being involved when a contents liquid is to be delivered through a delivery port. To solve such problem, a plug body 12 disposed in the mouth of a bottle 10 is provided with a delivery passage for delivering contents liquid received in the bottle 10, the delivery passage being provided with a filter 25. The filter 25 is composed of a filter film 25a for filtering bacteria to prevent the latter from permeating from upstream to downstream as seen in the direction of delivery, and a contents liquid holding member 25b of porous material that has microscopic pores, disposed upstream of the filter film 25a, the contents liquid holding member 25b being in planar contact with the filter film 25a.

  • Patent number: 7815049
    Abstract: A container packing filler includes an annular roll portion formed by folding one of axially opposite end portions of a stretchable tubular net radially outward and rolling the net toward the other end portion of the net, and a rigid holder portion provided at the other end portion of the net. The holder portion has sufficient axial length and a width greater than the diameter of a center hole of the annular roll portion so that, when the holder portion of the packing filler is squeezed into the center hole of the annular roll portion, the annular roll portion is expanded from the inside thereof by the holder portion and layers of the annular roll portion are unitarily rolled inward.

  • Publication number: 20090078608
    Abstract: A container packing filler (1) includes an annular roll portion (3) formed by folding one of axially opposite end portions of a stretchable tubular net (2) radially outward and rolling the net (2) toward the other end portion of the net (2), and a rigid holder portion (4) provided at the other end portion of the net (2). The holder portion (4) has a necessary and sufficient axial length and a maximum width (W) greater than the diameter (R) of a center hole (5) of the annular roll portion (3) so that, when the holder portion (4) of the packing filler (1) is squeezed into the center hole (5) of the annular roll portion (3), the annular roll portion (3) is expanded from the inside thereof by the holder portion (4) and layers of the annular roll portion (3) are unitarily rolled inward. Therefore, the bulging of only the outermost layer of the annular roll portion is prevented which may otherwise occur when the holder portion is squeezed.

  • Patent number: 7404814
    Abstract: An infusion vessel has a vessel body having an internal cavity to serve as an infusion medium space, a cylindrical discharge mouth continuing from a lower portion of the vessel body, a medicine chamber disposed in the discharge mouth and kept airtight against ambient air, and a separator intervening between the infusion medium space and the medicine chamber so as to keep the space in a liquid-tight state against the holder. The separator is subject to displacement, rotation or deformation such as to bring the infusion medium space into communication with the medicine chamber, so that the infusion vessel can be made ready for use by conducting a simple operation to mix the medicine with the infusion medium that have been separated from each other within the vessel during its normal state before use.
