Abstract

The present invention is a method and apparatus, in several embodiments, for providing protection in workplaces in which workers can be exposed to diseases and other contaminations from skin abrasions or punctures by contaminated objects. In its primary application it provides such protection at skin surfaces of healthcare patients into which needle electrodes have been inserted and, under certain conditions, can emerge. This bio-hazard occurs most often during patient-positioning when patients are unconscious due to anesthesia or other reasons. Protection is supplied in the first embodiment by a puncture-resistant head-covering; in the second by a pad that covers and secures needle electrodes, and; in a third as a tissue-penetrating, less hazardous stick-on electrode. The latter two embodiments have pressure-sensitive-adhesive coatings for adhesion to a patient'"'"'s skin.

Claims

1. A puncture-resistant covering for one or more needle electrodes, each having a sharp end and a lead-wire, the electrodes configured for electrical stimulation or recording of biological electrical potentials in clinical or surgical settings, the covering configured for use while the electrodes are inserted into a body to provide these functions, for the purpose of reducing risk of transferring disease that could result from medical personnel suffering skin-scrape or skin-puncture through contact with the sharp ends of said needles, said covering comprising:

a puncture-resistant patch of suitable shape and size having a front surface and a rear surface and having a thickness of less than one-quarter inch and having a pressure-sensitive adhesive existing on at least one-half of the rear surface for the purpose of securing the covering to the body and holding-in-place the needle electrode(s) and lead-wire(s) that it covers during its use.

2. The covering of claim 1 wherein at least one region of the covering presents as a tab that is devoid of the adhesive to facilitate its placement and/or removal.

3. The covering of claim 1 wherein, during its use, the front surface contains one or more words and/or designs configured to:

identify or express caution regarding the existence of the needle electrode(s) which it covers, and/or;

communicate a preferred orientation of the covering with respect to the covered needle electrode(s) for optimization of its application and/or removal, and/or;

draw attention to the covering'"'"'s presence to help ensure that, in the process of removing all the needle electrode(s) with the coverings, the chance of any needle electrode(s) being “

missed”

would be reduced.

4. The covering of claim 1, further comprising one or more additional layers.

5. The covering of claim 1, further comprising a release liner on the adhesive.

6. A stock of the coverings of claim 1, wherein the stock comprises a plurality of unit coverings provided on sheets or rolls of release material.

7. The stock of claim 6, wherein the release material can be cut, torn, or separated at perforations to yield separate units.
