DETAILED DESCRIPTION OF THE DRAWINGS

[0021]The degree of colour change can be measured by determining the value of ΔE* (euclidean distance) on the ingress of fluid between the layers—the larger the value of ΔE* the greater the colour change. This leads to and increased probability of perception of failure of barrier properties. With regards to this C*, L*, a*, b* (The three basic coordinates represent the lightness of the color (L*, L*=0 yields black and L*=100 indicates white), its position between red / magenta and green (a*, negative values indicate green while positive values indicate magenta) and its position between yellow and blue (b*, negative values indicate blue and positive values indicate yellow), and ΔE* values (all of which are universally recognized parameters with regard to colour within the art—CIE 1976 commission Internationale de l'Eclairage) may be determined using a spectrophotometer such as an SP62 provided by X-Rite of Grandville Mich. This method can also be use...

Abstract

A puncture indicating glove comprises a bilayer formed by an inner glove layer and an outer glove layer, the outer glove having an opacity in the range of 23-34%. The opacity of the over glove is controlled by the inclusion in the over glove of a fine particulate material, in particular selected from the group comprising titanium dioxide, silica, barite powder, barium sulphate, barium carbonate, calcium carbonate, gypsum, clay, talc, alumina white, basic magnesium carbonate, zinc oxide. The inner glove has a chroma range C* which is controlled to result in a glove that indicates optimally with transparent liquid and strongly coloured liquids such as blood. The inner glove has a chroma C* which is greater than 30, advantageously greater than 40, more preferably greater than 43, and in particular greater than 46.

Description

CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to Great Britain Application No. GB 0718240.5 filed on Sep. 18, 2007 and to Great Britain Application No. GB 0801602.4 filed on Jan. 29, 2008, the contents of each of which are incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]The present invention relates to gloves, in particular surgical gloves which have puncture evident characteristics by means of which a wearer can easily identify if the glove has been pierced.[0003]Surgical gloves perform an important function of protecting the wearer's hands from exposure to bodily fluids such as blood which might be infected and hence present a health risk as well as protecting the patient's internal organs from exposure to sweat and the like from the surgeons hands. Accordingly, the integrity of the liquid barrier formed by the glove is very important. In practice, surgical gloves are used within an environment where there is a risk of piercing, fo...
