Introduction

This procedure is based on JJF1002-2010 "national measurement procedures for the preparation of rules", with reference to JJF1059.1- "Measurement Uncertainty Assessment and Presentation", GB 9706.20-2000 "Medical electrical equipment Part 2. Diagnostics And safety requirements for the treatment of laser equipment ", GB 11748-2005" carbon dioxide laser treatment machine ", GB 12257- 2000 "helium-neon laser treatment machine general technical conditions", IEC 60825-2007 "laser product safety", YY0307- 2011 "continuous wave doped neodymium yttrium aluminum garnet laser treatment machine", and according to the actual test of the problem, the JJG 581-1999 "Medical laser source" was partially revised. --- to expand the scope of the test range, the detection range for the continuous laser source and pulsed laser source. --- Adjusted references to references and terminology. - According to the current development of technology, the original process outlined in the contents of a partial revision. - Partial changes to the technical requirements based on the actual situation of the verification. deletion of the cooling system and leakage Safety requirements (the test can not be effectively achieved), modified the light and light guide system technical requirements. --- According to the medical laser source detection of the actual situation, in the measurement performance to increase the value of the relative error detection project. --- According to the actual situation of the test, the stability and reproducibility of the content to do a certain change. - Leakage current detector, reading microscope and displacement movement mechanism are removed from the verification equipment (no actual detection Method to achieve or through other equipment to complete), an increase of laser energy measurement device. --- adjust the list of test items. --- modify the instructions of the light test method, the light guide system to do the detection and merger. --- Remove the light guide system reflectance, transmission ratio of the detection method (the actual work can not be on the medical laser source Light guide system for demolition detection). - A description of the supplementary notes and cautions has been added to the verification method. --- on the results of the test results and verification of the contents of the cycle to do a certain change, the main increase "part of the qualified The request ". - Added an uncertainty analysis in the appendix, modified the template for verifying the original record and the certificate, deleted the Measurement schematics, special equipment structure (the test can not be removed light guide system, the actual test of this project has been deleted), warning sign. Medical laser source verification procedures

1 Scope

This procedure applies to the medical laser source (not including medical excimer laser treatment machine) the first test, follow-up test And the use of the inspection.

3 terminology

3.1 continuous laser source continuouswavelaser A laser source that can be continuously emitted at a time greater than or equal to 0.25 s. 3.2 pulsed laser source pulselaser A laser source that emits energy in the form of a single pulse or sequence pulse. The duration of a pulse is shorter than 0.25s.

4 Overview

The medical laser source is usually composed of a laser, a control section and an output section. The role of the laser part is to generate excitement Light, different laser working materials will produce different wavelengths of laser (see Appendix C), can achieve different therapeutic purposes. Laser control part of the main role is to adjust the medical laser source output laser energy, energy density, power, frequency, etc. Parameters and safety control of medical laser sources. The laser output part of the role is to make the output laser light to a specified location, one It consists of light guide system (including fiber). According to the different forms of output laser, can be divided into medical continuous laser source and medical With pulse laser source two categories.

5 Measurement performance requirements

5.1 Indicates optical power measurement Indicating that the light spot should be clearly visible, the power size, eye medical laser source does not exceed 1mW, other medical Light source does not exceed 5mW. 5.2 Repeatability 5.2.1 For medical continuous laser sources, measuring the repeatability of the output laser power for 10 min of continuous exposure should be better than
