Description

Technical Field

[0001] The invention relates to the field of laser resistance testing equipment, in particular to a surgical single laser resistance test box. Background Art

[0002] With the rapid development of science and technology, laser technology has been widely used in various fields, especially in various disciplines of medical and health care, with remarkable achievements. In order to ensure the safety of medical staff and patients during laser surgery, a series of relevant standards have been introduced internationally. For example: ISO11810-1 "Laser and related laser equipment - Test methods and classification of laser resistance of surgical sheets and (or) patient protective covers, Part 1: Primary ignition and penetration, ISOISO11810-2: 2007 (E) "Laser and related laser equipment - Test methods and classification of laser resistance of surgical sheets and (or) patient protective covers, Part 2: Secondary ignition, which is used to detect the laser resistance of surgical sheets and (or) patient protective covers in laser medical surgery. my country also has relevant standards, such as: YY / T 0855.1-2011 Test methods and classification of laser resistance of surgical drapes and / or patient protective coverings Part 1: Primary ignition and penetration; YY / T 0855.2-2011 Test methods and classification of laser resistance of surgical drapes and / or patient protective coverings Part 2: Secondary ignition, etc.

[0003] Since laser surgery may cause surgical drapes and / or patient protective coverings to ignite, become flammable, melt, penetrate, conduct heat, and reflect, and conventional surgical drapes are not laser-resistant, even special surgical drapes that claim to be laser-resistant may have a certain laser barrier, but their laser resistance varies greatly due to the composition or design of the material. Therefore, all surgical drapes and patient protective coverings that are nominally laser-resistant may need to be tested, which also depends on the requirements of the manufacturer or end user.

[0004] However, at present, my country does not have a relevant standard testing system, and is unable to detect and determine the laser resistance of a large number of related medical equipment products imported from abroad, and is unable to inspect and control the laser resistance of a large number of domestically produced surgical sheets and patient protective coverings. This has undoubtedly brought certain obstacles to the application of laser medical technology and affected its development.

[0005] Therefore, it is necessary to provide a set of surgical drape anti-laser test chambers that meet standard technical requirements to meet the quality inspection of various surgical drapes and related products in the domestic and foreign markets, so as to ensure the improvement of product quality and safeguard the personal safety of patients and medical staff.
