Abstract
This invention provides medical articles having antimicrobial efficacy and good barrier properties. In particular, the medical articles comprise a nonwoven material and a coating comprising chlorhexidine acetate and triclosan. The present invention is directed to articles comprising a material, such as a nonwoven material, and a coating comprising chlorhexidine acetate and triclosan. The articles are preferably medical articles such as gowns, shoe covers, drapes, wraps and caps. A coating having a combination of chlorhexidine acetate and triclosan on a material, such as a nonwoven material, has been found to provide effective, fast-acting antimicrobial activity, while minimally affecting the barrier properties of the material.
Description
Invention field
The present invention relates to the medical article with antibacterial efficacy and excellent barrier characteristic.
Background of invention
In the U.S., hospital acquired infections is also referred to as nosocomial infection, causes every year or causes almost 100,000 example dead.Disposable medical goods, such as gown, valance, shoe cover, wrappage and medicated cap are generally used for this para-infectious propagation is minimized.These goods are often dressed or are used the very short time, as being less than 10 minutes.
Many in these goods is be made up of non-woven material or fabric, spun-bonded/melt-blown/spunbond (SMS) laminated product of such as polypropylene fibre, and can form the barrier layer of keeping out microorganism and/or liquid.Liquid such as the ability of body fluid pervious is hindered to be important in medical environment.Some medical supplies, such as medical gown, be divided into multiple barrier properties level according to AAMI/ANSI PB70 standard, and this standard develops association by medical apparatus and instruments to propose and the standard ratified by American National Standard Committee.In AAMI/ANSI PB70 standard, be resistance to water for measuring the key test of material block characteristic: hydrostatic test: AATCC method of testing 127, it is formulated by Textiles in USA chemist and printing and dyeing Shi Xiehui.Hydrostatic test test under increased pressure material to the resistance of water permeation.Four barrier properties levels are had according to AAMI/ANSI PB70 standard.The material with AAMI level 1 grade is tested by spray hits, and is effective to impact infiltration.The example typically with the material of AAMI level 1 grade comprises basic clothes covering (basic cover gowns) and contagion gown (isolation gowns).The material on permeation with AAMI level 2 grade requires the hydrostatic pressure of at least 20 centimeter water columns by the water of material.The example typically with the material of AAMI level 2 grade comprises following goods: this based article provides basic protection, usually relative hour of the amount being exposed to liquid use and the time used shorter.The material on permeation with AAMI level 3 grade requires the hydrostatic pressure of at least 50 centimeter water columns by the water of material.The example typically with the material of AAMI level 3 grade comprises provides the obstruct of increase to protect and the goods usually used when the amount of liquid exposure is medium.There is the material not moisture permeable of AAMI level 4 grade.Surgical drage and gown usually have AAMI level 4 grade.
Some non-woven materials are coated with anti-biotic material to kill the microorganism of contact product surface.Antibacterial activity is measured by determining that the logarithm of the infective bacterial quantity after being exposed to antibiotic substance reduces.Such as, logarithm reduces the minimizing that 3 refer to 99.9%, and logarithm reduces the minimizing that 4 refer to 99.99%.Although use antimicrobial coating can contribute to reducing the micro organism quantity be present on surface on non-woven material, coating can damage the barrier properties of non-woven material sometimes, thus adds the probability of liquid infiltration.
Need in this area there is effective barrier properties and the non-woven material of the antibacterial activity of display fast-acting.Preferably, medical article can as killed a large amount of microorganism in short time period in 10 minutes, and such as 3 or 4 logarithms reduce (99.9% to 99.99%)." killing fast " due to microorganism can cut off the infection chain of a surface to another surface, and therefore this material will contribute to the propagation reducing hospital acquired infections.

These preparations are sprayed on fabric sample, until sample is evenly saturated.Saturation point range estimation is determined, because painting preparation wet fabric sample, causes when fully saturated that they become translucent.Then sample levels is positioned in wire rack mount, and air-dry in fume hood.In some cases, sample is placed in baking oven dry.
Use AATCC method of testing 100, test the antibacterial efficacy of sample with Gram-E. coli (ATCC#11229) and Gram-positive S staphylococcus (S.aureus) MRSA (ATCC#43300).After five minutes, determine that the logarithm of escherichia coli and MRSA reduces.The barrier properties of sample also adopts resistance to water: hydrostatic pressure experiment AATCC method of testing 127 is tested, and gets twice hydrostatic pressure reading, and is averaged by numerical value.The results listed in the following table.
Result shows, the high logarithm that the chlorhexidine acetate on SMS non-woven material and the combination of triclosan demonstrate escherichia coli and MRSA reduces, and which show effective antibacterial activity.In addition, by hydrostatic pressure experiment measuring, the barrier properties of the SMS non-woven material of coating remains on high value.On the contrary, the antibacterial activity demonstrated with samples of other combination coatings of independent single antibacterial or antibacterial but poor barrier properties, good barrier properties but the barrier properties of the antibacterial activity of poor antibacterial activity or difference and difference.Such as, for the sample being only coated with triclosan, the barrier properties of fabric is high, but antibacterial activity is very low.For the sample being only coated with hibitane free alkali, antibacterial efficacy is high, but barrier properties is poor.In addition, the sample being only coated with chlorhexidine acetate shows the antibacterial activity of barrier properties and the difference of going on business to MRSA.
