Introduction

Certain medical surgical laser applications in laser surgery may require anti-mono- and/or other patient protective covering. In the sterile surgical too Process, surgical drapes and/or other patient protective covering is necessary, while protecting the surrounding areas are not subject to liquid discharge and laser radiation accident Shot effect. Conventional surgical drapes and/or other protective covering patients do not have to have anti-laser resistance, only dedicated only requires a single surgery Laser anti-sex.

Laser-induced risks include, ignite, flammable, melting, penetration, heat transfer and reflection. Providing a laser barrier fabric and non-woven surgical Single material may also have other risks. In the operating room often have more than one potential cause ignition device (for example. fiber optic lighting systems, electronic surgical device Home, hot wire ignition device), this test method is only for laser-induced ignition source. YY/T 0855 for this part of the expected nominal single anti-laser surgery And/or patient trial was covered. In addition, the area of this product may have different materials or design. According to the manufacturer's nominal or End-user requirements, all nominal anti-laser areas may need to experiment.

CO2 laser offers the most challenging conditions for all medical laser. Burning/flammability test and the penetration test may find more Challenging laser wavelengths and laser delivery models, Q- exchange such as within nanosecond range. YY/T 0855 this part of the selection 20W CO2 laser (continuous wave) laser as a test.

Users of this test method should pay attention to, surgical drapes and/or other patient protective covering of anti-laser wavelength dependent, surgical drapes and / Or other protective covering patient should be tested at a wavelength of intended use. If the experiment using other wavelengths, power setting and delivery team Law, need to be explained.

YY /test results in this section T 0855 should not be used for other wavelengths and temporal patterns.

When used in combination than when used alone, a single anti-laser surgery patients or other protective covering performance might change.

1 Scope

YY/T 0855 This section applies to a nominal one-time use of anti-laser and repetitive use of surgical drapes and other patient protective cover It was the nonwoven and woven materials.

This section surgical drapes and other patient protective covering for the harm caused by the laser provides a standard test methods and classification, and It gives the corresponding classification system. This section does not include a general fire safety specification. Also, this section includes neither caused by other sources of ignition, do not Including laser-induced secondary ignition cover.

All materials will reflect a portion of the beam, the user must decide whether specular reflection may bring harm, but not in this section It involved.
