Definitions

  • Patent Document 1 discloses a puncture device including a suction plate, a grip portion, a cavity, a check valve, and an injection needle.
  • a puncture device including a suction plate, a grip portion, a cavity, a check valve, and an injection needle.
  • the technique disclosed in Patent Document 1 by lifting the grip portion upward, the inside of the cavity is made negative pressure and the suction plate sucks the skin. Then, the injection needle is punctured into the skin by releasing the grip portion.
  • the puncture assisting tool is a sticking portion that sticks to the skin and a guide portion that is arranged inside the sticking area in the sticking portion, and is a through hole through which a needle passes. Is formed, and includes a guide portion for guiding the movement of the needle.
  • FIG. 2 is a perspective view of the puncture aid 10.
  • FIG. 3 is a perspective view of the puncture assisting tool 10 cut in a plane passing through the guide portion 12 and the exhaust portion 14 described later.
  • FIG. 4 is a view of the puncture assisting tool 10 as viewed from above in FIG.
  • FIG. 5 is a cross-sectional view taken along the line AA shown in FIG.
  • the guide unit 12 is a member for guiding the movement of the needle 23, which will be described later.
  • the guide portion 12 has a cylindrical shape, and the cylindrical shaft is the same as the cylindrical shaft of the frame body 11.
  • the guide portion 12 is formed with a through hole 12a through which the needle 23 passes, which is formed along a cylindrical axial direction (vertical direction in FIG. 5).
  • the inner diameter of the guide portion 12 (in other words, the inner diameter of the through hole 12a) is formed so as to be slightly larger than the outer diameter of the needle 23 described later.
  • the inner diameter of the guide portion 12 may be formed to be 1.05 to 1.2 times the outer diameter of the needle 23.
  • the needle 23 is attached to the tip of the first plunger 22.
  • the outer diameter of the needle 23 should be small in order to reduce the possibility of causing pain to the living body.
  • the needle 23 has a hollow inside.
  • the pressure inside the frame 11 can be reduced by sucking the air inside the frame 11 of the puncture aid 10 by pulling up the second plunger 25 in the second syringe 24. ..
  • 6 (a) to 6 (c) are diagrams for explaining a usage example (example of a puncture method) of the puncture device 1.
  • the inner diameter of the guide portion 12 (in other words, the inner diameter of the through hole 12a) is formed so as to be slightly larger than the outer diameter of the needle 23 in order to guide the needle 23. .. Therefore, the distance L is so small that it is slightly larger than the outer diameter of the needle 23. As a result, the shear stress applied to the skin S by the needle 23 can be increased.
  • the needle 23 is punctured into the skin S in a state where the region other than the inside of the guide portion 12 in the skin S is attached to the puncture aid 30. Can be done. Since the distance between the center of the needle 23 and the inner surface of the through hole 12a of the guide portion 12 in the direction perpendicular to the direction in which the needle 23 punctures the skin S of the living body is small, the shear applied by the needle 23 to the skin S is small. The stress can be increased. As a result, the needle 23, which is easily buckled, can be punctured into the skin S without buckling. Further, since the needle 23 is guided by the guide portion 12 (in other words, supported by the guide portion 12) at the time of puncturing, it is possible to prevent the needle 23 from buckling. ..
