Abstract

A replaceable plastic protective cover to prevent damages to and to waterproof an infusion device attached to a person for receipt of periodic doses of drugs wherein the cover includes an annular flange with waterproof adhesive therearound to affix the same to the skin and a housing extends upward from said flange with a closable opening for access to the interior of the housing.

Claims

1. A protective waterproof cover for use with an infusion device, said device generally permanently affixed to a person for a period of time wherein said device may receive drugs periodically, said cover to waterproof and protect said device from damage comprising:

a transparent plastic housing surrounding and spaced from said infusion device including at least one flat surface and having a bottom edge and including strengthening means to restrict the collapsing of said housing to protect said infusion device from damage;

an annular flange surrounding said housing at said bottom edge and extending radially outward from said housing, said flange having an underside;

a waterproof releasable adhesive on said underside of

said flange; and

a waterproof door having an edge formed in said one flat surface to be opened for access to said infusion device and said door includes locking means to prevent entry of moisture when closed wherein said locking means includes a tongue projecting from said edge and a groove in said housing to receive said tongue therein by snapping action and lock the same.

2. A protective cover as defined in claim 1 wherein:

said plastic housing is resilient and may be deformed to grip said infusion device for injection of drugs and upon release said housing will return to its original shape.

3. A protective cover as defined in claim 1 wherein:

said housing is arcuate and at least one inflexible rib extends the length of said housing to stiffen said housing and restrict collapsing when force is applied to said housing.

4. A protective cover as defined in claim 1 wherein:

said housing has a pair of opposed flat ends and said door is formed in one of said ends.

5. A protective cover as defined in claim 1 wherein:

said at least one flat surface forms the top of said housing and said top is a hinged door for access to all of said device.

6. A protective cover as defined in claim 5 wherein:

said door includes a living hinge in the form of a thinning of said plastic for a predetermined distance.

7. A protective cover as defined in claim 6 wherein:

said housing includes a pair of opposed upwardly and inwardly tapered ends; and

said housing includes a pair of opposed upwardly and inwardly tapered sides between said end.

8. A protective cover as defined in claim 6 wherein said strengthening means are a plurality of stiffening parallel grooves formed in said housing to curtail collapsing of said housing when pressure is applied directly thereto.

9. A protective cover as defined in claim 1 wherein:

said strengthening means are a plurality of stiffening parallel grooves formed in said housing to curtail collapsing of said housing when pressure is applied directly thereto.
