Abstract

The invention relates to the technical field of therapeutic instruments, and relates to a fume purification control circuit for a medical laser system. The technical problem is to provide the medicallaser system fume purification control circuit capable of using an ion smoke sensor to compare and amplify generated fume, controlling a suction motor to work, and at the same time being combined witha timing controller to process harmful fume. The fume purification control circuit for the medical laser system comprises a comparator circuit module, an ion smoke sensor, a relay drive module and the like. The output end of the ion smoke sensor is connected with the input end of the comparator circuit module. The output end of the comparator circuit module is connected with the input end of therelay drive module. Compared with the prior art, the circuit provided by the invention can discharge harmful fume from indoor to outdoor. Harmful fume is purified by a purification device, and harmfulfume is environmentally treated. Harm caused by harmful fume of laser treatment to human is solved to ensure medical safety.

Description

technical field [0001] The invention relates to the technical field of therapeutic instruments, and relates to a smoke and dust purification control circuit of a medical laser system. Background technique [0002] Laser is another major invention of mankind since the 20th century after nuclear energy, computers, and semiconductors. It is called "the fastest knife", "the most accurate ruler", and "the brightest light". The principle of laser was discovered by the famous American physicist Einstein as early as 1916. Laser treatment is a conventional treatment method, which is commonly used in dermatology and gynecological diseases. Generally, small and medium-sized hospitals in China have laser treatment rooms. In the process of laser treatment, the cutting and vaporization of the tissue by the laser will produce harmful fumes with unpleasant smells. The staff and patients inhale these harmful fumes, which directly endanger their health, and these fumes blur the operator's si...
