Abstract
Abstract The invention refers to an electronic detector arranged in such a way that the electric conductivity between e.g. a surgeon and a patient can be measured. The detector is preferably placed in the shoes of the surgeon and is through contact members on one hand connected to the surgeon's body and on the other hand to the bedding on which the surgeon stands, preferably a floor having a certain electric conductivity, or a round for this purpose. By the fact that an electrically conductive operating table is electrically connected to the same bedding also the patient will be galvanically connected with said bedding. A detector arranged in this way can detect the conductivity between the surgeon and the patient and makes it possible to control possible biologic leakage, e.g. germ-containing liquid, through perforations in the operation gloves of the surgeon, at which infections in incisions can be avoided to a great extent.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
84 words
A method for detecting perforations in a protective element, such as a surgical glove worn by an operator such as a surgeon, during the performance of an operation, such as surgery, on an object, such as a patient, said method comprising the steps of: at regularly recurring time intervals during said operation, sensing the electrical conductivity through said operator, said protective element, and said object connected in series; and signaling an alarm in response to changes exceeding a predetermined level in said sensed conductivity.
Claim 2
Independent Claim
84 words
A method for detecting perforations in a protective element, such as a surgical glove worn by an operator such as a surgeon, during the performance of an operation, such as surgery, on an object, such as a patient, said method comprising the steps of: at regularly recurring time intervals during said operation, sensing the electrical conductivity through said operator, said protective element, and said object connected in series; and signaling an alarm in response to changes exceeding a predetermined level in said sensed conductivity.
Claim 3
Dependent Claim
28 words
The method according to claim 1 further including the step of periodically providing a discharge path to discharge static electricity across the series-connected operator, protective element, and object.
Claim 4
Dependent Claim
94 words
Apparatus for detecting and indicating perforations occurring in a protective element, such as a surgical glove, worn by an operator, such as a surgeon, said apparatus comprising: voltage level sensor means, having two input terminals, for sensing electrical conductivity of external circuitry connected across said input terminals; timed control means for, at regular intervals, connecting said protective element and said operator in series between said two input terminals; and alarm means responsive to the electrical conductivity sensed by said sensor means for providing a humanly perceptible signal when sensed conductivity exceeds a predetermined value.
Claim 5
Dependent Claim
94 words
Apparatus for detecting and indicating perforations occurring in a protective element, such as a surgical glove, worn by an operator, such as a surgeon, said apparatus comprising: voltage level sensor means, having two input terminals, for sensing electrical conductivity of external circuitry connected across said input terminals; timed control means for, at regular intervals, connecting said protective element and said operator in series between said two input terminals; and alarm means responsive to the electrical conductivity sensed by said sensor means for providing a humanly perceptible signal when sensed conductivity exceeds a predetermined value.
Claim 6
Dependent Claim
76 words
The apparatus according to claim 3 further comprising: a shoe having a heel portion which is adapted to be worn by said operator; wherein said voltage level sensor means, said timed control means and said alarm means are disposed in said shoe, preferably in said heel portion; and wherein said shoe includes an insole contact and an underside contact to which said two input terminals are connected, respectively, at said regular intervals by said control means.
Claim 7
Dependent Claim
41 words
The apparatus according to claim 4, wherein said contacts comprise an at least electrically semi-conductive material, said insole contact at least partly covering an inner surface and said underside contact at least partly covering an outer bottom surface of the shoe.
Claim 8
Dependent Claim
25 words
The apparatus according to claim 3, further comprising electronic switch means for periodically electrically connecting together said two inputs in order to discharge static electricity.
