Definitions

  • the present invention relates to a drug solution administration device.
  • Medicine administration devices that administer a desired amount of medicinal liquid to a living body at an appropriate time are known (see, for example, JP2013-500793A).
  • the medicine administration device has a needle that is inserted into the living body, and is attached to the body surface of the living body by an adhesive.
  • the present invention aims to solve the above-mentioned problems.
  • One aspect of the present invention is a drug solution administration device comprising: a catheter having a catheter body to be placed in a living body; an inner needle inserted into the catheter; a needle holding part that holds a base end of the inner needle; a needle member removably attached to the catheter; a holder that holds the base end of the catheter; an adhesive having an attachment surface to be attached to the body surface of a living body and a surface opposite to the attachment surface, a part of the surface being joined to the holder; and a release sheet that is overlaid on the attachment surface so as to cover the adhesive and is peelable from the attachment surface, the release sheet having an extension that extends in a proximal direction beyond the adhesive body, and when the needle holding part and the extension are viewed in a direction from the holder toward the adhesive body, at least a part of the needle holding part overlaps the extension.
  • a multi-needle consisting of a catheter and an inner needle
  • the holder adheresive
  • wrinkles may form on the adhesive when the inner needle is removed, resulting in insufficient application to the body surface.
  • the adhesive may peel off from the body surface and the catheter may fall out of the living body.
  • the needle holding portion and the extension portion are viewed in the direction from the holder toward the adhesive, at least a part of the needle holding portion overlaps with the extension portion. Therefore, before applying the adhesive to the body surface, the user can easily see the needle holding portion rather than the extension portion of the release sheet. This makes it difficult for the user to apply the adhesive to the body surface before removing the inner needle from the catheter.
  • the catheter can be placed stably.
  • the patch body includes a first attachment portion having a first attachment surface and a second attachment portion having a second attachment surface, the first attachment portion extends at least above the catheter body, and a portion of the surface of the second attachment portion opposite the second attachment surface is connected to the holder, and the release sheet includes a first sheet covering the first attachment surface and a second sheet covering the second attachment surface, and the second sheet may include the extension portion.
  • the tip of the catheter can be maintained inserted inside the body by attaching the first attachment part to the body surface, making it easier to then fix the holder to the body surface with the second attachment part.
  • the second sheet may have a covering portion that covers the second application surface and an operating portion that is folded back from the tip of the covering portion toward the base end, and the operating portion may have the extension portion.
  • the second sheet is folded back at the tip of the second application surface, so the second sheet can be easily peeled off by pulling the extension toward the base end.
  • the second sheet may have a curved slit and be formed in a spiral shape along the slit.
  • the second sheet can be easily peeled off from the patch by pulling the extension in the proximal direction.
  • the catheter has a catheter hub that holds the base end of the catheter body, and the holder has a base portion formed in a flat plate shape to which the patch is fixed, and a hub holding portion formed in a cylindrical shape, at least a tip of which is connected to the base portion, and into which the tip of the catheter hub is inserted and holds the tip of the catheter hub, and the hub holding portion may hold the catheter hub so that the axis of the catheter hub is inclined relative to the base portion.
  • This configuration allows the catheter to be more stably placed in the body because it is inclined relative to the body surface.
  • a connecting portion may be formed to releasably connect the needle holding portion and the extension portion.
  • the holder cannot be attached to the body surface unless the connection part is released. This makes it easier to avoid attaching the holder to the body surface before removing the inner needle.
  • the needle holding portion and the extending portion when the needle holding portion and the extending portion are viewed in the direction from the holder toward the patch, at least a portion of the needle holding portion overlaps with the extending portion. This makes it easier for the user to see the needle holding portion rather than the extending portion of the release sheet before applying the patch to the body surface. This makes it difficult for the user to apply the patch to the body surface before removing the inner needle from the catheter. As a result, by applying the patch to the body surface after removing the inner needle from the catheter, it becomes possible to stably place the catheter.
