Abstract

An infusion needle attachment which, although covering the infusion needle protruding from below, so as to effectively and desirably mask it from view at the injection site, is nevertheless also effectively used to guide the unseen needle into position, since a flap finger grip thereof is in the same plane as the needle and the user is thereby readily able to judge the desired location at which the point of the needle should make physical contact preparatory to the subcutaneous administration of a medicament to a patient using said needle.

Claims

1. In combination with an infusion needle for achieving subcutaneous placement thereof incident to the dispensing therethrough of a medicament to a patient, an infusion needle attachment comprising a disk-like body of a selected size adequate for delineating an operative area for making provision for the handling and for the positioning of said infusion needle, a hollow tubular member bounding a compartment for receiving said infusion needle disposed in a peripheral location in said operative area and at an angular orientation in relation thereto so as to cause an infusion needle seated in said compartment to project at said angular orientation in depending relation from beneath said body, and an upstanding flap of a foldable construction material foldably attached to said body along a line coincident with the center of said body and in aligned relation to said projecting infusion needle, said flap being in a medial location of said operative area and extending in spanning relation from said tubular member to a point adjacent a peripheral edge of said body so as to effectively serve as a finger grip during said subcutaneous placement of said infusion needle, whereby said aligning orientations of said flap and infusion needle contributes to the proper guiding of said infusion needle into said required subcutaneous position thereof with said body in covering relation thereover masking the presence of said position needle.

2. The combination as claimed in claim 1, wherein the construction material of said body and of said flap is elastomeric, whereby said body is readily adapted to assume a curvature conforming to the curvature of the patient'"'"'s anatomy receiving said infusion needle and said finger grip means is readily foldable flat against said body.

3. The combination as claimed in claim 1, wherein the construction material of said body and of said flap is flexible plastic, whereby said body is readily adapted to assume a curvature conforming to the curvature of the patient'"'"'s anatomy receiving said infusion needle and said flap is readily foldable flat against said body.

4. The combination as claimed in claim 1, wherein said compartment of said tubular member is comprised by a through bore and a counter bore to thereby present a shoulder therealong, whereby said infusion needle is adapted to be attached to tubing and said tubing seats against said shoulder during the projection of said infusion needle through said through bore.
