Description

Technical Field

[0001] This utility model relates to the field of laser head cleaning technology, and specifically to a laser head cleaning device. Background Technology

[0002] In modern medical practice, laser equipment is widely used in many fields such as surgery, dermatology treatment, and dentistry. The core component of these devices—the laser head—is highly susceptible to contamination of its optical window (i.e., the cleaning area) by biological contaminants such as blood, tissue fluid, and protein eschar during surgery. The adhesion of contaminants can significantly reduce the energy transmission efficiency and treatment precision of the laser, and may even lead to the risk of cross-infection among patients.

[0003] Currently, cleaning medical laser heads mostly relies on manual wiping. This method has significant drawbacks: First, uneven wiping pressure can easily scratch delicate optical lenses; second, it is difficult to completely remove organic contaminants that have carbonized and adhered firmly at high temperatures; third, if the alcohol or other disinfectants used during the cleaning process are not completely removed, their residue may cause irritation or harm to subsequent patients; finally, manual cleaning cannot create a closed, sterile environment, posing a risk of secondary contamination and operator exposure to chemical reagents. Therefore, we propose a laser head cleaning device. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a laser head cleaning device to solve the above-mentioned problems existing in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A laser head cleaning device includes a control box, a laser electrically connected to the control box, and a cleaning chamber disposed inside the control box. The top of the cleaning chamber has a base for docking the laser head. A water storage chamber is disposed around the base, and the water storage chamber has a water inlet. A drive chamber is disposed at the bottom of the cleaning chamber, and a clean air pump and a negative pressure pump are installed inside the drive chamber. A cleaning chamber is located between the water storage chamber and the drive chamber, and a through hole communicating with the cleaning chamber is opened on the base. A mesh plate is disposed between the cleaning chamber and the drive chamber. Filter chambers communicating with the cleaning chamber are respectively disposed on both sides of the cleaning chamber, and filter elements are installed inside the filter chambers. A heating fan is installed on one side of one filter chamber, and an air outlet is disposed on one side of the other filter chamber.

[0007] Furthermore, the inner wall of the base is fitted with a sealing ring to form a mechanical seal between the laser head and the laser head housing when the laser head is inserted.

[0008] Furthermore, the bottom of the grid plate is provided with a funnel-shaped liquid collection plate extending into the drive chamber, and the liquid collection plate is connected to the negative pressure pump through a pipe.

[0009] Furthermore, the grid plate is provided with a vortex-type ultrasonic atomizing nozzle coaxial with the through hole; the vortex-type ultrasonic atomizing nozzle is connected to the water storage chamber through a first pipeline and to the clean air pump through a second pipeline.

[0010] Furthermore, the clean air pump and the negative pressure pump in the drive chamber are connected in parallel and are respectively connected to the cleaning chamber and the liquid collection plate through independently controlled pipelines.

[0011] This invention provides a laser head cleaning device. It has the following beneficial effects:

[0012] The sealing ring embedded in the base forms a reliable mechanical seal with the laser head shell, completely isolating the entire cleaning process in a sealed cleaning chamber; effectively preventing external environmental microorganisms from contaminating the laser head, and also eliminating the leakage of cleaning aerosols containing biological contaminants, fully meeting the highest sterility requirements of medical operations, and fundamentally cutting off the path of iatrogenic infection caused by incomplete laser head cleaning.

[0013] By using a vortex-type ultrasonic atomizing nozzle set on a grid plate and coaxial with the through holes, the cleaning fluid can be efficiently atomized and subjected to a frontal, precise, and concentrated impact and wetting of the most critical end optical window of the laser head. The non-contact cleaning method can gently and thoroughly break down and remove contaminants such as bloodstains and tissue residues, avoiding potential damage to the optical surface of the expensive laser head caused by physical friction and significantly extending its service life.

[0014] By utilizing the combined action of a negative pressure pump and a funnel-shaped collection plate, the cleaning waste liquid can be recovered instantly and actively. The stripped contaminants are quickly drawn away through the grid plate with the liquid, preventing accumulation in the cleaning chamber and ensuring the cleanliness of subsequent cleaning media. It also facilitates the centralized, safe, and standardized treatment of waste liquid containing biohazardous substances, complying with medical waste management standards.

[0015] After the cleaning process is completed, a clean air pump can blow in clean air for preliminary purging. Combined with a closed-loop air circulation drying system consisting of a heated fan, dual-sided filter chambers, and filter elements, clean hot air can be delivered into the cleaning chamber, and moisture can be forcibly expelled, thereby achieving rapid and thorough drying of the laser head. This ensures that the laser head is immediately in a clean, dry, and sterile standby state after cleaning, enabling "ready-to-use" in continuous surgeries and greatly improving diagnostic and treatment efficiency.

[0016] The entire cleaning and drying process is integrated and controlled by the control box, which can be operated with one button, reducing the risk of manual intervention and contact with contaminants by medical staff. It integrates multiple functions (cleaning, waste liquid recycling, and drying) into one, promoting the standardization and process of postoperative maintenance of laser heads, and is particularly suitable for high-intensity and fast-paced medical environments.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] See attached document Figures 1-5A laser head 2 cleaning device includes a control box 1, a laser electrically connected to the control box 1, and a cleaning chamber 3 disposed inside the control box 1. The top of the cleaning chamber 3 is provided with a base 21 for docking the laser head 2. A water storage chamber 31 is provided around the base 21 of the cleaning chamber 3, and a water inlet 311 is provided on the water storage chamber 31. A drive chamber 6 is provided at the bottom of the cleaning chamber 3, and a clean air pump 7 and a negative pressure pump 8 are installed inside the drive chamber 6. A cleaning chamber 32 is provided between the water storage chamber 31 and the drive chamber 6, and a through hole communicating with the cleaning chamber 32 is provided on the base 21. A mesh plate 5 is provided between the cleaning chamber 32 and the drive chamber 6. Filter chambers 10 communicating with the cleaning chamber 3 are respectively provided on both sides of the cleaning chamber 3, and filter elements are installed inside the filter chambers 10. A heating fan 4 is installed on one side of one filter chamber 10, and an air outlet duct 11 is provided on one side of the other filter chamber 10.

[0025] The inner wall of the base 21 is fitted with a sealing ring to form a mechanical seal between the laser head 2 and the outer shell of the laser head 2 when the laser head 2 is inserted.

[0026] The bottom of the grid plate 5 is provided with a funnel-shaped liquid collection plate 51 extending into the drive chamber 6, and the liquid collection plate 51 is connected to the negative pressure pump 8 through a pipe.

[0027] The mesh plate 5 is provided with a vortex-type ultrasonic atomizing nozzle 9 coaxial with the through hole; the vortex-type ultrasonic atomizing nozzle 9 is connected to the water storage chamber 31 through a first pipeline and to the clean air pump 7 through a second pipeline.

[0028] The clean air pump 7 and the negative pressure pump 8 in the drive chamber 6 are connected in parallel and are respectively connected to the cleaning chamber 32 and the liquid collection plate 51 through independently controlled pipes.

[0029] Working principle: The used medical laser head 2 is inserted into the base 21 on top of the cleaning chamber 3. The sealing ring is tightly fitted with the outer shell of the laser head 2 to form a closed cleaning chamber 32 environment.

[0030] After the system is started, the medical-grade cleaning fluid in the water storage chamber 31 is delivered to the vortex-type ultrasonic atomizing nozzle 9 through the first pipeline. At the same time, the clean air pump 7 provides gas power through the second pipeline. The nozzle 9 generates micron-sized fine atomized particles and takes advantage of its coaxial installation position with the laser head 2 to directly and precisely impact, wet and soften the contaminants at the end of the laser head 2, achieving efficient and non-damaging cleaning.

[0031] While the cleaning is in progress, the negative pressure pump 8 is started; the waste liquid after cleaning and the pollutants that have been removed are drawn down through the grid plate 5 under the action of gravity and airflow, collected by the funnel-shaped liquid collection plate 51, and continuously drawn out of the cleaning chamber 32 through the connected pipes and into the dedicated waste liquid collection unit to ensure that the cleaning process is not contaminated by waste liquid residue.

[0032] After the cleaning process is completed, the clean air pump 7 switches to the drying mode and blows clean air into the cleaning chamber 32 to remove residual droplets. Then, the heating fan 4 starts, and the hot air generated is purified by the filter element in the filter chamber 10 on one side and enters the cleaning chamber 3. After carrying the moisture, it is discharged from the filter chamber 10 on the other side and the air outlet 11, forming a clean and dry hot air circulation to quickly dry the laser head 2.

[0033] After the entire automated process is completed, medical staff can remove the completely clean, dry and sterile laser head 2 for direct use in the next medical operation.
