  • Patent number: 11826076
    Abstract: There is provided a medical needle with a protector that allows separately molded hub and protector to be easily assembled together. A medical needle with a protector (1) includes: a hub (3) that supports a needle tube (2); a protector (4) capable of storing the needle tube (2); a first lock unit (42a, 42b, 73) that locks the hub (3) to the protector (4) capable of unlocking in a first state; and a second lock unit (43, 75) that locks the hub (3) to the protector (4) incapable of a transition to the first state in a second state. The protector includes a large cylindrical portion (41), a protrusion piece (43), and a width-increased portion (42). The width-increased portion (42) is provided on the outer peripheral side of the protrusion piece (43) and has a minor axis and a major axis. The protrusion piece (43) is formed integrally with the large cylindrical portion (41) on the major axis side of the width-increased portion (42).

  • Patent number: 9849664
    Abstract: A thermal stencil making unit that makes a stencil of a perforated image on a thermal gauze by moving a thermal print head having the plurality of heat elements relative to the thermal gauze tightly stretched in a gauze frame detachably set in a unit housing, includes a head-protecting member that moves between a protection position where the thermal print head is protected and a protection release position where a protective state is released. The thermal stencil making unit moves the head-protecting member to the protection position when the gauze frame is not set in the unit housing and moves the head-protecting cover member from the protection position to the protection release position, in conjunction with an operation of setting the gauze frame in the unit housing.
