Surgical and medical garments and materials incorporating shear thickening fluids

Abstract

A surgical garment in the form of a surgical gown, a surgical glove or a surgical mask incorporates a shear thickening fluid as a layer on at least one of the inner and outer surface of the garment, the viscosity of which shear thickening fluid increases to inhibit penetration of the garment.

Description

technical field

[0001] The present invention relates to surgical garments and materials containing shear viscous fluids to increase their penetration resistance, surgical garments such as surgical gowns, surgical gloves, wound care products and the like. Background technique

[0002] Shear thickening fluids, or STFs, are a class of magneto-rheological particles suspended within the liquid that change their orientation and increase viscosity when shear is applied to it or the liquid is exposed to an electric charge or magnetic field , a liquid whose viscosity increases temporarily or reversibly. However, when the inducing factor is removed, this induced effect disappears and the liquid returns to its normal viscosity.

[0003] The nature and composition of STF are various. In general, STF exhibits a characteristic characteristic of what may be referred to as non-Newtonian flow, characterized by a marked increase in its viscosity with increasing shear. They generally consis...
