Claims

[Scope of utility model registration request]

(1) A tubular first tube made of a material that can be bonded with a hardening adhesive.
A medical device comprising a component, and a tubular second component having a through hole into which the first component can be inserted and bonded via a curable adhesive, and made of a material that is difficult to bond with a curable adhesive. , at least a portion of the inner wall surface of the through hole has a locking portion having a portion having an unequal distance from the axis to the wall surface in the axial direction of the through hole, and a surface perpendicular to the axis on the inner wall surface of the through hole. a rotation preventing portion having a portion having unequal distances from the axis to the wall surface; a joining space formed by the outer surface of the first component inserted into the through hole and the inner wall surface of the through hole of the second component; , and a hardened part of a hardening adhesive that fills the remaining gap in the joining space, and the hardened part filled in the locking part and the rotation prevention part engages with the locking part and the rotation prevention part. A medical device characterized in that the first part and the second part do not rotate relative to each other and do not come off.

(2) The medical device according to claim 1, wherein the first tubular part is a puncture needle and the second tubular part is a hub.

(3) Scope of utility model registration claim 1 where the locking part is a groove
The medical device described in Section 1 or Section 2.

(4) According to the scope of claim 3 of the utility model registration, a plurality of grooves are provided in the axial direction of the second part, and the depth of the grooves becomes shallower as it goes deeper from the opening. Medical equipment listed.
