## Abstract

A shield seals out moisture over a portion of a wearer's limb. The shield may be used to protect chronic Intravenous (IV) sites preventing moisture from reaching the IV site and provides a moisture tight compartment for carrying personal items during aquatic activities. The shield is made of a thermoplastic elastomer material which freely stretches and includes two opposing very small entry openings which stretch to form collar regions at each stretched opening providing an area versus a line of contact between the shield and skin thereby sealing out moisture. The improved sealing of the present invention allows many activities previously denied to patients. The shield is preferably generally spherical but may be elliptical, football shaped, oval, or other shapes and may have one closed end or multiple openings for fingers or toes.

## Claims

### Claim 1

A shield for chronic Intravenous (IV) site, the shield comprising:
a body made from a very high elongation material;
at least one opening in the body having relaxed diameter less than two inches; and
the entry opening stretchable to fit over a patient's limb and form a moisture proof seal.

### Claim 2 (depends on 1)

The shield of claim 1, wherein the very high elongation material has a minimum elongation of 800 percent.

### Claim 3 (depends on 2)

The shield of claim 2, wherein the very high elongation material has a minimum elongation of 1200 percent.

### Claim 4 (depends on 3)

The shield of claim 3, wherein the very high elongation material has an elongation of about 1,500 percent.

### Claim 5 (depends on 1)

The shield of claim 1, wherein the at least one opening has a relaxed diameter of less than 1.5 inches.

### Claim 6 (depends on 5)

The shield of claim 5, wherein the at least one opening has a relaxed diameter of about 0.5 inches.

### Claim 7 (depends on 1)

The shield of claim 1, wherein the at least one opening comprises two openings on opposite sides of the shield.

### Claim 9 (depends on 1)

The shield of claim 1, wherein the at least one opening comprises a first opening having a diameter less than two inches and five smaller second opening opposite the first opening configured to receive five fingers of a patient.

### Claim 10 (depends on 1)

The shield of claim 1, wherein the shield has a generally spherical relaxed shape.

### Claim 11 (depends on 1)

The shield of claim 1, wherein the shield has a generally elliptical relaxed shape.

### Claim 12 (depends on 1)

The shield of claim 1, wherein the shield has a generally oval relaxed shape.

### Claim 13 (depends on 1)

The shield of claim 1, wherein the shield is made from a thermoplastic elastomer material.

### Claim 14 (depends on 13)

The shield of claim 13, wherein the thermoplastic elastomer material has a hardness of Shore A 8+/−5.

### Claim 15 (depends on 14)

The shield of claim 14, wherein the thermoplastic elastomer material has a tensile strength of between 800 and 1,200 PSI.

### Claim 16 (depends on 5)

The shield of claim 5, wherein the thermoplastic elastomer material consists essentially of Styrene-Ethylene/Butylene-Styrene, a CoPolymer, Anti-Oxidants, and UPS oil.

### Claim 17

A shield for chronic Intravenous (IV) site, the shield comprising:
a body made from a material having an elongations of at least 800 percent;
at least one opening in the body having relaxed diameter less than two inches; and
the opening stretchable to fit over a patient's limb and form a moisture proof seal.

### Claim 18 (depends on 17)

The shield of claim 17, wherein the thermoplastic elastomer material consists essentially of Styrene-Ethylene/Butylene-Styrene, a CoPolymer, Anti-Oxidants, and UPS oil.

### Claim 19

A shield for chronic Intravenous (IV) site, the shield comprising:
a body comprising:
a thermoplastic elastomer material;
a diameter between three and twelve inches;
an elongations of at least 800 percent;
a hardness of Shore A 8+/−5; and
a tensile strength of between 800 and 1,200 PSI;
at least one opening in the body having relaxed diameter of less than two inches; and
the opening stretchable to fit over a patient's limb and form a moisture proof seal.

### Claim 20 (depends on 19)

The shield of claim 19, wherein the thermoplastic elastomer material comprises between ten and twenty percent SEBS and between eighty and ninety percent USP oil.
