Definitions

  • An injector 200 'shown in FIG. 48 is a device that can be used in combination with the lancet assembly 100' to fire a "lancet body with the tip of the puncture needle 105 'exposed".
  • the injector 200 ' has a "plunger 204' that can be engaged with the rear end of the lancet body and that fires the lancet body in the puncturing direction" (see FIG. 51).
  • the lancet assembly 100' is inserted from the front end opening 214 'of the injector 200'.
  • FIG. 51 When inserted to some extent, as shown in FIG.
  • the puncture depth adjusting mechanism has a “cylindrical member having an uneven portion and a step portion”.
  • the concavo-convex portion is provided on the cylindrical member so that the normal line of the surface forming the concavo-convex portion of the cylindrical member (that is, the concavo-convex surface) is substantially parallel to the axial direction of the injector, while complementary to part of the concavo-convex portion
  • a complementary shape portion having a general shape is provided in the injector casing, and the contact between the part of the concavo-convex portion of the cylindrical member and the complementary shape portion of the injector casing is maintained by the pressing force provided from the spring member. .
  • a “click feeling” suitable for adjusting the puncture depth by turning the cylindrical member with the fingertip is provided to the user.
  • the lancet assembly has a pair of rearward extending portions extending rearward from the cap head portion.
  • the rearward extension of the lancet cap extends along the outer surface on the outer surface of the holder body.
  • the rearward extending portion of the lancet cap extends along the outer surface on the outer surface of the holder body.
  • the inner surface of the rearward extending portion of the lancet cap and the outer surface of the holder body are close to or in close contact with each other.
  • at least a part of the inner side surface of the rearward extending portion of the lancet cap and at least a part of the outer side surface of the body of the holder have a complementary shape.
  • the rearward extension part of the lancet cap has a long shape and extends rearward so that the free end extends outward.
  • the lancet assembly of the present invention has a shape feature in which the rearward extension portion of the lancet cap is suitably extended.
  • the rearward extending portion of the lancet cap extends long in light of the relationship between the position of the needle tip and / or the position of the rear end of the needle tip protecting portion.
  • the rear extension portion extends rearward so that the free end / tip of the rear extension portion of the lancet cap is positioned rearward of the needle tip position of the puncture needle or the rear end of the needle tip protection portion.
  • an ultrafine puncture needle can suitably prevent the bending of the needle tip.
  • the trajectory of the puncture needle becomes substantially linear, and as a result, the pain felt by the puncture subject (that is, the blood sample) during puncture can be reduced.
  • This is not limited to a specific theory, but is considered to be caused by a phenomenon that the puncture site of the blood sample is “squeezed out” by the puncture needle.
  • “bending” of the puncture needle is prevented, and even if the user is different, a constant and same removal operation can always be secured, so that the puncture tip portion is substantially constant. An exposure state can be obtained. Therefore, even if the users are different, the puncture trajectory of the puncture needle becomes substantially constant, and the effect that the variation among users is reduced can also be achieved.
  • FIGS. 4 and 5 When using the puncture device, as shown in FIGS. 4 and 5, first, an operation of loading the lancet assembly 100 into the injector 200 is performed. The loading is performed by fitting the lancet assembly 100 into the front end opening 201 of the injector 200 as shown in the figure. Specifically, the lancet assembly 100 is inserted into the injector 200 so that the holder 170 of the lancet assembly 100 is partially fitted into the lancet assembly receiving member 202 of the injector 200. During such loading, the lancet will engage the plunger 220 of the injector.
  • the lancet will abut against the plunger 220, but since the lancet is pushed into the injector, the plunger will retract within the injector.
  • the lancet body 140 (see FIG. 2) held and fixed to the holder 170 presses the plunger 220, and the plunger 220 moves backward.
  • the plunger 220 is provided with a fire spring 220a.
  • a fire spring 220 a is disposed inside the body cylinder portion 221 of the plunger 220.
  • the lancet assembly receiving member 202 is provided at the front end opening of the injector, and receives the lancet assembly inserted during use.
  • the lancet assembly can be loaded into the injector so that a part of the lancet holder 170 fits in the receiving member 202 (see FIGS. 4 and 5).
  • the lancet assembly receiving member 202 preferably has a cylindrical shape as a whole.
  • the local bending portion 265 of the holder holding member 260 is positioned slightly inside the inner surface of the lancet assembly receiving member 202. More specifically, it is preferable that the top of the dome-shaped portion 265 ′ of the local curved portion 265 is positioned at least inside the inner surface of the assembly receiving member 202.
  • the trigger lever is operated before the lancet cap is removed, and the lancet assembly is Even when pulled out of the injector, the advancement of the plunger connected to the lancet is prevented by the “further protrusion 230c” of the trigger lever, resulting in the above safety.

Abstract

L'invention concerne un injecteur comprenant un mécanisme d'ajustement de profondeur de ponction comprenant : un élément cylindrique pourvu d'une portion en saillie dépassant d'un piston, une portion irrégulière, et une portion en gradin; et un élément ressort disposé côte à côte avec l'élément cylindrique dans la direction axiale de l'injecteur. Un boîtier d'injecteur est pourvu d'une portion à forme complémentaire ayant une forme complémentaire d'une partie de la portion irrégulière, ladite partie de la portion irrégulière de l'élément cylindrique et la portion à forme complémentaire du boîtier d'injecteur, sont maintenues en contact l'une avec l'autre par une force de pression fournie par l'élément ressort. Lorsque le piston est déplacé vers l'avant pour ponctionner, la portion saillante du piston vient impacter la portion en gradin de l'élément cylindrique, empêchant le mouvement vers l'avant du piston. Pour ajuster la profondeur de ponction, l'élément cylindrique est mis en rotation autour de son axe, permettant de modifier la hauteur à laquelle la portion saillante du piston vient impacter la portion en gradin, et modifiant ainsi la distance de déplacement vers l'avant du piston.
