## Abstract

Portable and disposable apparatus for leak testing surgical and/or examination gloves which may be worn on the body of the user to permit convenient detection of glove leaks during diagnostic procedures. In one embodiment there is provided an electrolyte-containing pouch worn on the body of the user and into which gloved hands may be inserted for evaluation. A leak in a glove permits the electrolyte to penetrate the glove and contact the skin of the wearer to close an electrical circuit and trigger an alarm.

## Claims

### Claim 1

An apparatus for detecting holes or leaks in a surgical or examination glove worn on the hand of a user, said apparatus comprising:
a first electrically conductive lead having a first end connected to an electrical power test unit and a second end in electrical contact with the body of the user;
a second electrically conductive lead having a first end connected to said power test unit and a second end in electrical contact with an absorbent material positioned within a fluid impervious covering worn on the body of the user, said absorbent material being capable of absorbing and containing an electrolyte solution;
an opening extending through said covering and in communication with a cavity defined in said absorbent material for insertion of the gloved hand therein for contacting said electrolyte solution to test for leaks in the glove; and
means for measuring electrical properties between said first lead and said second lead when the electrolyte solution enters said glove through a leak in said glove and causes a completion of an electrical circuit between said first lead and said second lead, said means for measuring being in electrical continuity with said first lead and said second lead and producing an output signal in response to the completed electrical circuit indicative of a leak in the glove.

### Claim 2 (depends on 1)

The apparatus of claim 1, wherein the second end of the first electrically conductive lead comprises an EKG electrode.

### Claim 3 (depends on 1)

The apparatus of claim 1, wherein the absorbent material comprises a sponge, and the fluid impervious covering comprises plastic.

### Claim 4 (depends on 1)

The apparatus of claim 1, wherein the electrolyte solution comprises a saline solution.

### Claim 5 (depends on 1)

The apparatus of claim 1, wherein the means for measuring electrical properties comprises an alarm which sounds when the electrical circuit is completed.

### Claim 6 (depends on 1)

The apparatus of claim 1, further comprising strap means for securing the apparatus to the body of the user.

### Claim 7

A surgical gown, comprising:
a body portion;
arm portions connected to the body portion; and
an apparatus attached to the body portion of the gown for detecting holes or leaks in a surgical or examination glove worn on the hand of a user, the apparatus comprising:
a first electrically conductive lead having a first end connected to an electrical power test unit and a second end in electrical contact with the body of the user,
a second electrically conductive lead having a first end connected to the power test unit and a second end in electrical contact with an absorbent material positioned within a fluid impervious covering worn on the body of the user, the absorbent material being capable of absorbing and containing an electrolyte solution,
an opening extending through the covering and in communication with a cavity defined in the absorbent material for insertion of the gloved hand therein for contacting the electrolyte solution to test for leaks in the glove, and
means for measuring electrical properties between the first lead and the second lead when the electrolyte solution enters the glove through a leak in the glove and causes a completion of an electrical circuit between the first lead and said second lead, the means for measuring being in electrical continuity with the first lead and the second lead and producing an output signal in response to the completed electrical circuit indicative of a leak in the glove.
