an injection needle cartridge including a substantially columnar retaining member for retaining an injection needle axially penetrating therethrough so that the injection needle projects from both end surfaces thereof; a first holder member having a first bottom plate facing to one end surface of the retaining member and a first slider section erected from the first bottom plate so as to be in contact with the outer peripheral side surface of the retaining member to hold the retaining member; a second holder member having a second bottom plate facing to the other end surface of the retaining member and a second slider section erected from the second bottom plate so as to be in contact with the outer peripheral side surface of the retaining member to hold the retaining member, wherein the second holder member is configured to contain the retaining member in a containing space formed by the first bottom plate and the second bottom plate oriented to face to each other, and to be rotatable relative to the first holder member about the axis of the retaining member; and a substantially cylindrical inner ring constituting a rotation restricting mechanism for restricting the relative rotation of the paired holder members in a state of being placed around the retaining member and being positioned on the inner periphery side of the first or second slider section, wherein the containing space is axially extendable and retractable in the state in which the slider sections are alternately displaced along the outer periphery of the retaining member, and is not axially retractable in the state in which the extreme end faces of the slider sections face to each other; and the injection needle of the retaining member penetrates through and projects from the bottom surface plates when the containing space is retracted axially;
an injection needle cartridge including a substantially columnar retaining member for retaining an injection needle axially penetrating therethrough so that the injection needle projects from both end surfaces thereof; a first holder member having a first bottom plate facing to one end surface of the retaining member and a first slider section erected from the first bottom plate so as to be in contact with the outer peripheral side surface of the retaining member to hold the retaining member; a second holder member having a second bottom plate facing to the other end surface of the retaining member and a second slider section erected from the second bottom plate so as to be in contact with the outer peripheral side surface of the retaining member to hold the retaining member, wherein the second holder member is configured to contain the retaining member in a containing space formed by the first bottom plate and the second bottom plate oriented to face to each other, and to be rotatable relative to the first holder member about the axis of the retaining member; and a substantially cylindrical surrounding ring constituting a rotation restricting mechanism for restricting the relative rotation of the paired holder members in a state of being placed around the first and second slider sections about the axis of the retaining member, wherein the containing space is axially extendable and retractable in the state in which the slider sections are alternately displaced along the outer periphery of the retaining member, and is not axially retractable in the state in which the extreme end faces of the slider sections face to each other; and the injection needle of the retaining member penetrates through and projects from the bottom surface plates when the containing space is retracted axially;
Specifically, in the outer peripheral surface of the first member 151, a groove-shaped concave part 151 r that is spiral with the axial direction being the center is formed. On the other hand, on the inner peripheral surface of the second member 152, a spiral convex part 152 r engaging with the concave part 151 r of the first member 151 is formed. For this applicator 15, by the engagement of convex part 152 r with the concave part 151 r, the whole of the applicator 15 can be extended and retracted in the axial direction according to the relative rotation of the first member 151 and the second member 152.
As shown in FIGS. 18 and 19, the retaining member 10 is a substantially columnar member that is formed with a large-diameter part 103 provided at a middle position in the axial direction in an offset manner, and provided with the small-diameter parts 104 at both ends in the axial direction. The small-diameter parts 104 are formed so that the axial length of one small-diameter part 104A is longer than that of the other small-diameter part 104B. The small-diameter part 104A having a longer axial length is configured so that the inner ring 31 is placed around, and when the inner ring 31 is placed around, the small-diameter part 104A can still project in the axial direction. The inner ring 31 can advance and retreat in the axial direction and can turn in the circumferential direction in a state of being placed around the small-diameter part 104A. The inner ring 31 placed around the small-diameter part 104A is formed so as to be integral with the large-diameter part 103 when the engagement pieces 311 are retracted toward the inside in the radial direction.
a substantially cylindrical inner ring constituting a rotation restricting mechanism for restricting the relative rotation of the paired holder members about the axis of the retaining member in a state of being placed around the retaining member and positioned on the inner periphery side of the first slider section or the second slider section,
wherein the containing space is axially retractable in the state in which the slider sections are alternately displaced along the outer periphery of the retaining member to allow the injection needle of the retaining member to penetrate through and to project from the bottom surface plates to be capable of an injection, and
wherein the containing space is axially extendable to place the injection needle in the containing space after the injection, in which the cylindrical inner ring is configured to,
(i) allow the first and second holder members to rotate relative to each other to a position where the extreme end faces of the slider sections of the first and second holder members face to each other, and then
(ii) restrict the relative rotation of the first and second holder members in said position.
a substantially cylindrical surrounding ring constituting a rotation restricting mechanism for restricting the relative rotation of the paired holder members in a state of being placed around the first and second slider sections,
wherein the containing space is axially extendable to place the injection needle in the containing space after the injection, in which the cylindrical surrounding ring is configured to,
(a) an injection needle cartridge comprising:
a substantially cylindrical inner ring constituting a rotation restricting mechanism for restricting the relative rotation of the paired holder members in a state of being placed around the retaining member and being positioned on the inner periphery side of the first or second slider section,
wherein the containing space is axially retractable in the state in which the slider sections are alternately displaced along the outer periphery of the retaining member to allow the injection needle of the retaining member to penetrate through and to project from the bottom surface plates to be capable of an injection;
(ii) restrict the relative rotation of the first and second holder members in said position;
(b) a body part which contains a medicine and is provided with a front end surface for allowing one side of the injection needle of the injection needle cartridge to be pierced; and
(c) a cap section which is a bottomed substantially cylindrical member placed around the front end side of the body part and is provided with a through hole for allowing the other side of the injection needle of the internally accommodated injection needle cartridge to penetrate through,
wherein the cap section is configured to enable the paired holder members to turn relative to each other and to be capable of advancing and retreating to axially retract the containing space with respect to the body part.
