There are several kinds of medical laser treatment system, that is Nd:YAG, CO2, Argon Ion and etc., which are begun to use for animal experiments and clinical case.
The important things to use appropriately the medical laser system are as follows.
One is safety of laser system itself, another is method of maintenance, that is, safety control by user.
In this paper, safety of laser system (YAG laser and CO2 laser) and how to control it were studied.
As for hard-ware, it is concluded that following 4 items are thought to be necessary for safety of medical laser system
1. System trouble is detectable before it is use.
2. In case of appearance unusual conditions in the system, laser irradiation must be stopped automatically.
(Interlock system)
3. Alarm should be continued to ring during laser irradiation.
4. In case of stand-by mode, whatever laser irradiation's switch become “ON”, laser beam must not be irradiated.
In addition to these, general notices of use and safety control or soft-ware
Ware also reported in this paper.
