Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of air dust removal devices, and specifically refers to an automatic smoke exhaust device for the laser treatment process. Background Technique
[0002] As an advanced medical means, laser treatment has been widely used in the medical field due to its high precision, non-invasiveness and good treatment effect. During the laser treatment process, a certain amount of smoke is generated due to the action of laser energy on tissues. The generation of these smokes mainly stems from reactions such as tissue gasification, carbonization and combustion. However, traditional smoke exhaust devices have many defects.
[0003] Firstly, the relative position of the smoke exhaust hood is usually fixed, and it is extremely inconvenient to adjust. If the smoke exhaust hood is too far from the laser emission end, the smoke exhaust effect will be poor, and the smoke cannot be effectively removed in time, affecting the treatment environment and the doctor's operation vision; if it is too close, it will block the doctor's line of sight and interfere with the normal progress of the treatment, making it difficult to design the position of the smoke exhaust hood to satisfy both aspects.
[0004] Secondly, the exhausted smoke may contain harmful substances such as harmful bacteria. Most traditional smoke exhaust devices directly discharge after simple filtration, lacking the function of disinfecting the smoke, which is likely to cause environmental pollution and pose a potential threat to the health of medical staff and patients.
[0005] In summary, in order to overcome the above defects of traditional laser treatment smoke exhaust devices, it is necessary to develop a new type of automatic smoke exhaust device. Content of the Utility Model

The smoke sensor 10 and the negative pressure exhaust fan 9 are both electrically connected to the PLC controller.
[0033] The working principle of the automatic smoke exhaust device for the laser treatment process of the present utility model is as follows: A negative pressure is generated by the negative pressure exhaust fan 9, so that the smoke generated near the laser treatment head 1 can be sucked into the smoke exhaust hood 3. The smoke enters the disinfection component 7 and the filtration and adsorption component 8 in sequence through the hose 6 for disinfection and filtration and adsorption treatment to achieve the purpose of purified discharge. The micro electric push rod 5 can adjust the position of the smoke exhaust hood 3 according to actual needs.

[0037] The using process of the automatic smoke exhaust device for the laser treatment process of the present utility model is as follows:
[0038] 1. Before laser treatment, first check whether all components of the device are properly connected and powered. The power supply can be external power supply or built-in battery power supply, and ensure the normal operation of the negative pressure exhaust fan 9, the micro electric push rod 5, the smoke sensor 10, the disinfection component 7 and the filtration and adsorption component 8, etc.
[0039] 2. Align the laser treatment head 1 with the treatment site of the patient. According to the characteristics of the treatment site and the operating habits of the doctor, start the micro electric push rod 5 through the control button 20 to adjust the position of the smoke exhaust hood 3 so that it can effectively collect smoke and does not interfere with the doctor's line of sight and operation.
[0040] 3. Turn on the laser treatment device for treatment. During the treatment process, the generated smoke will be sucked in through the smoke suction hole 4 on the smoke exhaust hood 3 under the action of the negative pressure exhaust fan 9.
[0041] 4. The smoke first enters the hose 6 and then enters the disinfection component 7. The ultraviolet lamp 16 in the disinfection component 7 causes the nano-titanium dioxide coating to disinfect bacteria and the like in the smoke.
[0042] 5. The disinfected smoke then enters the filter adsorption component 8. The double-layer filter screen 18 preliminarily filters larger particulate matter, and the activated carbon adsorption box 19 adsorbs the odor and fine particles in the smoke.
[0043] 6. The smoke sensor 10 monitors the smoke concentration in real time. When the concentration exceeds the set threshold, the automatic control system will increase the power of the negative pressure exhaust fan 9 to enhance the smoke exhaust effect; when the concentration drops below the set value, the negative pressure exhaust fan 9 resumes its normal operating power.
[0044] 7. After the treatment is over, turn off the laser treatment device and this automatic smoke exhaust device, and clean and maintain the device for future use.
[0045] In the disinfection component, the nano-titanium dioxide coating fixedly provided outside the glass tube 15 will produce a photocatalytic reaction under the irradiation of the ultraviolet lamp 16. The photocatalytic reaction can generate reactive oxygen species such as hydroxyl radicals and superoxide anions. These reactive oxygen species have strong oxidation ability and can decompose and destroy the cell structure of microorganisms, producing a disinfection effect on the passing smoke.
[0046] The above describes the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the creation of the present utility model, design structurally similar ways and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present utility model.
