Description

Technical Field

[0001] This utility model relates to the field of water technology for medical endoscopes, and in particular to a sterile circulating water supply and cleaning system for endoscopes. Background Technology

[0002] The use of water for endoscopy is a crucial step in the cleaning and disinfection process of hospital endoscopes, as it directly affects the effectiveness of endoscope cleaning and disinfection and patient safety.

[0003] Chinese patent CN205389919U discloses a clean water supply system for laboratory animals, comprising: a sterile water tank, cylindrical in shape, with its upper left end serving as the water inlet of the supply system and connected to a high-pressure water pump, and its lower right end serving as the water outlet of the supply system and threadedly connected to one end of a negative pressure valve body; an ultraviolet germicidal lamp connected to a controller in the supply system is installed on the top of the sterile water tank; an activated carbon device and a reverse osmosis device are arranged sequentially from top to bottom in the middle of the sterile water tank, and both ends of the activated carbon device and the reverse osmosis device are connected to the inner wall of the sterile water tank. The water supply system of this invention has a simple structure, low implementation cost, and good practical application effect. It can ensure that the water quality meets the requirements for drinking water for laboratory animals in a long-term stable manner, effectively preventing bacterial growth, and promoting the rational utilization of water resources.

[0004] However, activated carbon in this technical solution does not have a direct bactericidal ability, is inconvenient to use, and the bactericidal effect of the reverse osmosis device is affected over time, resulting in poor bactericidal effect. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a sterile circulating water purification system for endoscopes. This system achieves the function of disinfecting both the water tank and the pipeline by installing an ozone generator in the pipeline, thus solving the problem of poor disinfection effect in existing technologies.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An endoscope-use sterile circulating water purification system includes: a water tank for storing water, a water pump disposed adjacent to one side of the water tank, a pipeline connecting the water pump to the water tank, a water point disposed on one side of the pipeline, and an ozone generator disposed on one side of the water pump and connected to the pipeline for disinfection.

[0008] Preferably, the pipeline includes: a first pipe disposed at the water outlet end of the water tank and a second pipe connected to the first pipe, the two forming a water circulation system of the pipeline.

[0009] Preferably, the first pipeline is equipped with the water pump and the ozone generator, and the ozone generator is located at the output end of the water pump.

[0010] Preferably, the second pipe has a drain outlet at one end near the water tank.

[0011] Preferably, the water tank is equipped with an ultraviolet sterilizer.

[0012] Preferably, a spray nozzle is provided at the top of the inside of the water tank.

[0013] Preferably, the bottom of the water tank is provided with a liquid outlet.

[0014] Preferably, a chemical cleaning agent port is provided on one side of the water tank.

[0015] Preferably, the chemical cleaning agent port is installed on a water inlet pipe for introducing pure water, and the water inlet pipe is connected to the nozzle.

[0016] The beneficial effects of this utility model are as follows:

[0017] (1) This utility model places the ozone generator at the output end of the water pump. This arrangement can maximize the disinfection effect of ozone because the water pressure at the output end of the water pump is usually high, which helps ozone dissolve in water, improves the solubility and mixing efficiency of ozone, thereby enhancing the oxidation effect, and ensuring that the water is in full contact with ozone during the flow process, thus improving the disinfection efficiency.

[0018] (2) This utility model uses a UV sterilizer installed in the water tank. The UV sterilizer uses UV light of a specific wavelength to irradiate the water flow, destroying the DNA or RNA structure of microorganisms in the water, so that they lose their ability to reproduce, thereby achieving the effect of sterilization and disinfection. The sterilization is very efficient. Moreover, the UV sterilization does not require the addition of any chemical substances to the water, so it will not change the physical and chemical properties of the water, nor will it increase the odor or produce disinfection byproducts such as trihalomethanes, thereby further ensuring the cleanliness of the water tank.

[0019] (3) This utility model provides a chemical cleaning agent port on one side of the water tank, which is connected to the nozzle. This means that when cleaning the water tank, chemical cleaning agents, such as sodium hypochlorite, bleaching powder and other chlorine-containing disinfectants, can be introduced to further kill various microorganisms in the water tank and ensure the cleanliness of the water tank.

[0020] In summary, this utility model has the advantages of high disinfection efficiency, good sterilization effect, no pollution and convenient use. Attached Figure Description

[0026] Example 1

[0027] like Figure 1As shown, this embodiment provides a sterile circulating water purification system for endoscopy, including: a water tank 1 for water storage, a water pump 2 disposed on one side of the water tank 1, a pipeline 3 connecting the water pump 2 and the water tank 1, a water point 4 disposed on one side of the pipeline 3, and an ozone generator 5 disposed on one side of the water pump 2 and connected to the pipeline 3 for disinfection. The ozone generated by the ozone generator 5 cleans and disinfects the pipeline 3 and the water tank 1 respectively, ensuring both the cleanliness of the water tank 1 and the cleanliness of the pipeline 3. This disinfection of the purification system from two aspects ensures that the water at the water point 4 is always in a clean state and can be used directly, which is convenient. Multiple water points 4 can be set.

[0028] Ozone is a strong oxidant that can quickly destroy the cell structure of microorganisms. It has a good killing effect on bacteria, viruses, fungi and other microorganisms. It has strong bactericidal ability, thus quickly forming a sterile environment. Moreover, ozone will quickly decompose into oxygen during the disinfection process and will not produce harmful substances, making it environmentally friendly.

[0029] Meanwhile, the pipeline 3 includes a first pipe 31 disposed at the water outlet of the water tank 1 and a second pipe 32 connected to the first pipe 31. The two form a water circulation system for the pipeline 3, which can effectively avoid the waste of water resources.

[0030] In this embodiment, the first pipe 31 is equipped with the water pump 2 and the ozone generator 5, and the ozone generator 5 is located at the output end of the water pump 2. This arrangement can maximize the disinfection effect of ozone because the water pressure at the output end of the water pump 2 is usually high, which helps ozone dissolve in water, improves the solubility and mixing efficiency of ozone, thereby enhancing the oxidation effect, and ensuring that the water is in full contact with ozone during the flow process, thus improving the disinfection efficiency.

[0031] In this embodiment, a drain outlet 33 is provided at one end of the second pipe 32 near the water tank 1. After ozone disinfection, the mixed liquid in the pipe 3 can be directly discharged from the drain outlet 33, avoiding secondary pollution when using water.

[0032] In this embodiment, an ultraviolet sterilizer 11 is installed in the water tank 1. The ultraviolet sterilizer 11 uses ultraviolet light of a specific wavelength (mainly UVC band, wavelength 200-280nm) to irradiate the water flow, destroying the DNA or RNA structure of microorganisms in the water, causing them to lose their ability to reproduce, thereby achieving the effect of sterilization and disinfection. Its sterilization is very efficient, and the ultraviolet disinfection does not require the addition of any chemical substances to the water, so it will not change the physical and chemical properties of the water, nor will it increase the odor or produce disinfection byproducts such as trihalomethanes, thereby further ensuring the cleanliness of the water tank 1.

[0033] Of course, a nozzle 12 is provided at the top of the inside of the water tank 1. The nozzle 12 is used to receive pure water from the outside to ensure smooth water flow.

[0034] In addition, the bottom of the water tank 1 is provided with a liquid outlet 13. After the water tank 1 is disinfected, the mixed liquid is discharged directly from the water tank 1 to avoid secondary pollution.

[0035] The disinfection process in this embodiment is as follows: First, pure water is continuously introduced into the water tank 1, and the ultraviolet sterilizer 11 is turned on to disinfect the water tank 1. Then, part of the water enters the pipeline 3 through the water pump 2, while the other part of the water remains in the water tank 1. At the same time, the ozone generator 5 starts to work and releases ozone to disinfect the pipeline 3. At this time, the water point 4 is in the closed state. After the pipeline 3 is disinfected, the drain port 33 is opened to drain the disinfected water in the pipeline 3 and the drain port 33 is closed. Then, part of the water will flow back into the water tank 1. At this time, the outlet port 13 is opened and the input of pure water is stopped. Then, the remaining water in the water tank 1 is completely drained and the outlet port 13 is closed. At this time, the water tank 1 and the pipeline 3 are both disinfected.

[0036] Example 2

[0037] like Figure 2 As shown, components that are the same as or corresponding to those in Embodiment 1 are referred to using the same reference numerals as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is as follows:

[0038] A chemical cleaning agent port 61 is provided on one side of the water tank 1. The chemical cleaning agent port 61 is connected to the nozzle 12. When cleaning the water tank 1, chemical cleaning agents, such as sodium hypochlorite, bleaching powder and other chlorine-containing disinfectants, can be introduced to further kill various microorganisms in the water tank 1 and ensure the cleanliness of the water tank 1. Finally, the waste liquid is discharged from the outlet 13.

[0039] The chemical cleaning agent port 61 is installed on the water inlet pipe 6 for introducing pure water, and the water inlet pipe 6 is connected to the nozzle 12. The chemical cleaning agent is directly introduced into the water inlet pipe 6, which can more effectively clean the water inlet pipe 6 and then flow smoothly into the water tank 1 for disinfection. The nozzle 12 can ensure that the chemical cleaning agent is evenly distributed throughout the water tank 1, improve the uniformity and thoroughness of cleaning, and further ensure the cleanliness of the water tank 1.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
