Description

Technical Field

[0001] This invention relates to the field of medical device disinfection technology, and more specifically to a root canal file disinfection device. Background Technology

[0002] Root canal treatment, a crucial procedure in dentistry, requires root canal files that undergo rigorous sterilization after use to prevent cross-infection. However, current root canal file sterilization equipment presents several problems. Firstly, incomplete sterilization makes it difficult to thoroughly clean and disinfect the files, leaving bacteria and debris that pose an infection risk to patients. Secondly, existing equipment is complex to operate and lacks automation, failing to automatically select appropriate sterilization programs and parameters based on the number of files and their level of contamination, increasing the workload of medical staff. Furthermore, inappropriate material selection makes the equipment susceptible to corrosion during sterilization, reducing its lifespan and potentially contaminating the files. Additionally, some equipment suffers from poor sealing, making it vulnerable to external environmental contamination and affecting sterilization effectiveness.

[0003] To address the aforementioned issues, researchers have proposed several solutions. For example, patent CN110368128A discloses a dedicated disinfection and cleaning device for burs, root canal files, and gutta-percha points. This device uses a specific cleaning structure and disinfection method to disinfect these items. However, it may lack intelligent control, failing to automatically adjust disinfection parameters according to different situations, and its material selection and sealing treatment may not be perfect.

[0004] Another patent, CN115444589A, provides a root canal file and a root canal treatment instrument, which mainly uses laser for rinsing and disinfection. However, it may have limitations in disinfection function, as it cannot combine multiple disinfection methods or achieve precise control over the disinfection process. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an innovative intelligent and efficient root canal file disinfection device. By integrating technologies such as precision cleaning, multi-mode disinfection, efficient drying, and intelligent control, it achieves comprehensive, efficient, and safe disinfection of root canal files.

[0006] To solve the above-mentioned technical problems, the technical solution proposed by this invention is as follows:

[0007] A root canal file disinfection device, characterized in that it includes: a housing, a cleaning device, a disinfection and drying device, and an intelligent control module.

[0008] The box is divided into two layers: the upper layer is a cleaning device for cleaning root canal files, and the lower layer is a disinfection and drying device for disinfecting and drying root canal files. The box door has a double-door interlocking design to ensure a completely sealed state when the door is closed, while facilitating the safe and quick handling of root canal files by medical staff. A sealing strip is installed between the two doors, and the box door is equipped with a safety lock and an emergency unlocking device to deal with emergencies. Inside the box, there is a movable root canal file fixing device consisting of an elastic clamp and a tray. The elastic clamp is fixed on the tray, and the clamping force is monitored in real time by a pressure sensor. The control system automatically adjusts the clamping degree of the clamp according to a preset algorithm to ensure that the root canal files are stably fixed during cleaning, disinfection, and drying, while avoiding damage to the root canal files due to excessive clamping force.

[0009] The cleaning device includes a cleaning fluid circulation system, a cleaning fluid output pipe, a gas-liquid mixing device, nozzles, and a cleaning fluid storage tank. The cleaning fluid circulation system consists of a cleaning fluid circulation pump and a cleaning fluid filter. The cleaning fluid circulation pump is located at the bottom of the cleaning fluid storage tank. The pump draws used cleaning fluid from the bottom of the tank and delivers it to the gas-liquid mixing device through the cleaning fluid output pipe. The cleaning fluid filter is located above the pump. The collection tank delivers used cleaning fluid to the filter, where it is filtered and then returned to the storage tank, achieving recycling of the cleaning fluid and reducing costs. The gas-liquid mixing device is installed at the connection between the pipe and the nozzle. Using the Venturi principle, it mixes gas and cleaning fluid to form microbubbles, which are then delivered to the nozzle through the pipe. The nozzle is installed on the end of the pipe facing the root canal file. These microbubbles clean the root canal file 360 ​​degrees without dead angles through the nozzle, improving the cleaning effect. The nozzle ensures that the cleaning fluid and bubbles are evenly sprayed on all parts of the root canal file, thoroughly removing dirt and bacteria from the surface of the file.

[0010] The disinfection and drying equipment includes a chemical disinfection device, a high-temperature steam disinfection device, an ultraviolet disinfection device, and a drying device.

[0011] The chemical disinfection device consists of a disinfectant circulation pump, a disinfectant filter, a spray pipe, a disinfectant storage tank, and spray heads. The disinfectant is an environmentally friendly disinfectant. The disinfectant storage tank provides the liquid source for the circulating spray and is equipped with a level sensor to monitor the disinfectant level in real time. When the level is too low, an alarm is triggered to remind the user to add disinfectant. The disinfectant storage tank also has a filling port for convenient addition of disinfectant. The disinfectant circulation pump is located at the bottom of the disinfectant storage tank and connects to the spray pipe, providing power for the circulation of the spray liquid. This allows the disinfectant to enter the spray pipe from the disinfectant storage tank and be dispersed to the spray heads. The spray heads are installed on the end face of the spray pipe facing the root canal file, and they spray the disinfectant evenly onto the surface of the root canal file for chemical disinfection. The disinfectant filter is located above the disinfectant circulation pump. Used disinfectant enters the disinfectant filter through a collection tank. The disinfectant filter removes impurities and contaminants from the used disinfectant before it returns to the disinfectant storage tank, achieving disinfectant recycling.

[0012] The high-temperature steam sterilization device consists of a heating element, a steam-water separator, a water tank, and a steam output pipe. The heating element is located inside the lower part of the water tank, using a high-efficiency electric heating tube with an external insulation layer. The steam-water separator is located on the left side of the water tank and connected to it via a pipe. After the heating element heats the water in the tank to boiling point and generates steam, the steam is transported to the steam-water separator through the steam output pipe. The steam-water separator uses centrifugal separation technology to effectively separate water and steam, ensuring that the output steam is pure and free of impurities. The water tank is made of high-strength, corrosion-resistant materials, including polyethylene or polypropylene, and is used to store the water used to generate steam. It is equipped with a liquid level sensor and a water inlet. The liquid level sensor monitors the water level in the tank in real time and issues an alarm when the water level is too low, reminding the user to add water. The water inlet allows the user to easily add water to the tank. The steam output pipe is made of heat-insulating material and is equipped with a valve and a pressure sensor. The valve controls the steam output flow rate, and the pressure sensor monitors the steam pressure in real time to ensure that the steam pressure is within a safe range.

[0013] The ultraviolet disinfection device consists of a high-efficiency ultraviolet lamp and an intelligent sensing and control device. The intelligent sensing and control device automatically adjusts the irradiation angle and intensity of the ultraviolet lamp according to the position and number of root canal files.

[0014] The drying device consists of a blower, a hot air blower, an inlet duct, an outlet duct, and a humidity sensor. The blower and hot air blower are connected between the inlet and outlet ducts. The blower draws air into the hot air blower through the inlet duct. The hot air blower uses electric heating to heat the air, which is then sent into the chamber of the sterilization and drying device through the outlet duct. The hot air circulates inside the chamber, evaporating the moisture on the surface of the root canal files. The humidity sensor is installed inside the chamber to monitor the humidity in real time. When the humidity reaches the set value, the drying device stops operating to ensure that the root canal files are thoroughly dried. The inlet duct is equipped with a valve and a filter. The valve controls the airflow, and the filter removes impurities and contaminants from the air to prevent secondary contamination of the root canal files.

[0015] The intelligent control module includes an automated control system, a fault diagnosis and alarm system, and a user interface. The intelligent control module is located on the control panel on the top of the enclosure and is connected to the sensors and actuators of each device via cables.

[0016] The automated control system monitors the equipment's operating status in real time through built-in temperature, humidity, pressure, and liquid level sensors. Based on the number of root canal files, the degree of contamination, and user settings, the system automatically selects the disinfection program and parameters using advanced control algorithms such as fuzzy control and neural networks, achieving intelligent operation. For example, when there are many root canal files or the contamination is severe, the system automatically selects an enhanced disinfection program, extending the disinfection time and increasing the disinfection intensity; when there are few root canal files or the contamination is mild, the system automatically selects a conventional disinfection program, saving energy and time.

[0017] The fault diagnosis and alarm system monitors the equipment's operating status in real time, issuing alarms and displaying specific fault information when abnormalities are detected. Employing sensor and microprocessor technology, the system can quickly and accurately detect equipment faults and promptly notify users for maintenance. For example, when the temperature sensor detects excessively high internal temperatures, it issues an alarm and automatically stops the heating element to prevent damage; when the pressure sensor detects excessively high steam pressure, it issues an alarm and automatically opens the valve on the steam output pipe to release some steam and reduce pressure.

[0018] The user interface provides an intuitive operating interface that supports touch screen operation, remote control, and data recording. Users can easily set device parameters and operating modes, and view device operating status and disinfection records via the touch screen. The remote control function allows users to operate the device remotely via mobile devices such as smartphones and tablets, making it convenient for users to use in different situations. The data recording function can record device operating parameters, disinfection records, and other information, facilitating data analysis and management for users.
