Description
Technical Field
[0001] This invention relates to the field of medical auxiliary equipment, specifically to a high-efficiency cleaning and disinfection device for medical devices. Background Technology
[0002] Metal or plastic medical devices used for nursing or treatment, especially small instruments used in operating rooms, are sometimes accidentally contaminated by dirt during use. If spare or alternative instruments cannot be provided immediately, emergency rapid cleaning and disinfection are generally adopted before reuse. Emergency cleaning and disinfection includes rinsing and disinfecting bacteria or viruses. Currently, some emergency treatments for instruments involve rinsing followed by boiling for disinfection, while others involve placing the instruments in a container filled with disinfectant. For example, the utility model patent with authorization announcement number CN209631721 U discloses a cleaning and disinfection device for operating room nursing, which describes: "...including a cleaning and disinfection tank...a first electric motor can drive a turntable to rotate, thereby moving the medical instruments in the cleaning basket and causing the disinfectant in the cleaning and disinfection tank to flow...a drive gear indirectly drives a moving plate to move upward, thereby allowing the cleaned medical instruments to be removed from the disinfectant, and medical personnel do not need to have their hands in contact with the disinfectant when handling the medical instruments..." Cleaning and disinfection methods such as rinsing, soaking in disinfectant solutions, or boiling are often time-consuming, and some instruments may not be fully sterilized, remain damp after disinfection, or be unusable in emergencies due to high temperatures. Therefore, there is a need for a device that integrates rapid cleaning, drying, and low-temperature sterilization to efficiently clean and disinfect medical devices, meeting the needs of emergency use. This case arises from this need. Summary of the Invention
[0003] To overcome the shortcomings of the prior art, the present invention discloses a high-efficiency cleaning and disinfection device for medical devices, including a cleaning and drying assembly, a disinfection and sterilization assembly, an isolation door assembly, a lifting assembly, an instrument rack assembly, and an outer casing. This invention integrates a washing and drying assembly, a disinfection and sterilization assembly, an isolation door assembly, and a lifting assembly into a single device. The top opening of the washing and drying chamber faces the bottom opening of the disinfection and sterilization chamber, with the isolation door assembly positioned between these two openings. When the isolation door assembly is closed, it isolates the internal cavities of the washing and drying chamber and the disinfection and sterilization chamber, creating independent, sealed cavities. The instrument rack assembly can then be placed inside the washing and drying chamber, where the washing and drying assembly cleans, dehumidifies, and dries the instruments. When the isolation door assembly is open, it connects the internal cavities of the washing and drying chamber and the disinfection and sterilization chamber, allowing the instrument rack assembly to be lifted into the disinfection and sterilization chamber by the lifting assembly. After the isolation door assembly closes again, the disinfection and sterilization assembly disinfects and sterilizes the instruments placed on the instrument rack assembly using the synergistic effect of hydrogen peroxide gas and low-temperature plasma. This allows for rapid and efficient cleaning, drying, and low-temperature sterilization of instruments, meeting the needs of emergency medical device use.

[0017] As described above, the advantages of the high-efficiency cleaning and disinfection device for medical devices provided by this invention are as follows: A cleaning and drying assembly, a disinfection and sterilization assembly, an isolation door assembly, and a lifting assembly are integrated into the same device. The disinfection and sterilization assembly is positioned above the cleaning and drying assembly. The washing and drying chamber of the cleaning and drying assembly is equipped with a washable nozzle, a hot air drying nozzle, and a dehumidifier connected to the washing and drying chamber.

Both the top and bottom of the washing and drying chamber are open, and an openable and closable isolation door assembly is provided between these openings. The lifting assembly is located at the bottom of the washing and drying chamber. This invention arranges the top opening of the washing and drying chamber and the bottom opening of the disinfection chamber facing each other and connecting or separating them through the isolation door assembly. Firstly, by closing the isolation door assembly between the open washing and drying chamber and the open disinfection chamber, the internal cavities of the two chambers can be separated, forming independent, sealed cavities. The instrument rack assembly can then be placed inside the washing and drying chamber, where the washing and drying components clean, dehumidify, and dry the instruments on the rack assembly with hot air. Secondly, by opening the isolation door assembly, the internal cavities of the washing and drying chamber and the disinfection chamber can be connected, allowing the instrument rack assembly to be raised into the disinfection chamber by the lifting component. After the isolation door assembly closes again, the disinfection and sterilization components can then disinfect and sterilize the instruments placed on the rack assembly. This allows for rapid and efficient cleaning, drying, and low-temperature sterilization of instruments, meeting the requirements for medical device disinfection. The invention addresses several key needs: firstly, it addresses the urgent need for sterilization; secondly, by incorporating a cold plasma sterilization component within the sterilization assembly, the synergistic effect of hydrogen peroxide gas and low-temperature plasma enables rapid and thorough sterilization of instruments. Furthermore, the low-temperature plasma sterilization also meets the needs of instruments that cannot withstand high temperatures; thirdly, it integrates the washing and drying assembly, sterilization assembly, isolation door assembly, and lifting assembly into a single device. The lifting assembly automatically transfers the instrument rack assembly from the washing and drying chamber to the sterilization chamber within a sealed environment. This avoids the time-consuming and potentially contaminated issues associated with separate washing and sterilization processes requiring manual transfer, thus enabling highly efficient operation. The invention is rationally designed, simple in structure, low in cost, and easy to promote. Attached Figure Description

At this time, both the left door 31 and the right door 32 of the isolation door assembly 3 are open. The system also commands the electromagnet 24 of the disinfection and sterilization assembly 2 to be energized to generate magnetic force and commands the lifting cylinder 41 of the lifting assembly 4 to actuate. The action involves the lifting cylinder 41, where the support plate 42 on the cylinder rod lifts the instrument rack assembly 5 above it and moves it upward until the instrument rack assembly 5 enters the disinfection chamber 21 and its top plate 52 is attracted by the electromagnet 24 inside the disinfection chamber 21 and suspended inside the disinfection chamber 21. Then, the cylinder rod of the lifting cylinder 41 descends, causing the support plate 42 to return to its initial position inside the washing and drying chamber 11. Next, the rotating cylinder 341 of the isolation door assembly 3 is instructed to operate, closing the left door 31 and right door 32 of the isolation door assembly 3 according to the corresponding closing sequence.
[0044] The electronic control system instructs the vacuum pump 23 of the sterilization component 2 to activate, creating a negative pressure inside the sterilization chamber 21; then it instructs the plasma generator 22 to start injecting hydrogen peroxide gas into the sterilization chamber 21. Under conditions close to room temperature (30-60℃), plasma is generated by ionizing the gas, using its highly active particles to quickly sterilize viruses and bacteria on the instruments; after sterilization, the sterilization chamber door 211 of the sterilization chamber 21 is opened, and the instruments can be taken out for emergency use.
[0045] If the instrument rack assembly 5 attached to the electromagnet 24 needs to be lowered, it can be raised and supported by the left door 31, right door 32 and lifting cylinder 41 of the opening isolation door assembly 3 before the electromagnet 24 is de-energized. After the electromagnet 24 is de-energized, the instrument rack assembly 5 can be lowered.
[0046] This invention integrates a washing and drying assembly 1, a disinfection and sterilization assembly 2, an isolation door assembly 3, and a lifting assembly 4 into a single device. The top opening of the washing and drying chamber 11 and the bottom opening of the disinfection chamber 21 are arranged facing each other. When the isolation door assembly 3, located between the two openings, is closed, it can separate the internal cavities of the washing and drying chamber 11 and the disinfection chamber 21, forming independent sealed cavities. The instrument rack assembly 5 can then be placed inside the washing and drying chamber 11, where the washing and drying assembly 1 cleans, dehumidifies, and dries the instruments placed on it with hot air. When the isolation door assembly 3 is opened, it connects the internal cavities of the washing and drying chamber 11 and the disinfection chamber 21, allowing the instrument rack assembly 5 to be lifted into the disinfection chamber 21 by the lifting assembly 4. After the isolation door assembly 3 is closed again, the disinfection and sterilization assembly 2 can disinfect and sterilize the instruments placed on the instrument rack assembly 5 using the synergistic effect of hydrogen peroxide gas and low-temperature plasma. This allows for rapid and efficient cleaning, drying, and low-temperature sterilization of instruments, meeting the needs of emergency use of medical devices.
[0047] The above is only one specific embodiment of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention using this concept shall be considered as infringing the protection scope of the present invention.
