Description
Technical Field
The invention relates to the field of design and manufacture of endoscope washing sterilizers. The xenon excimer light source sterilizing technology is the third generation low temperature sterilizing technology, and the active oxygen cluster excited by the xenon excimer light source in the ambient air is a high-efficiency, safe and environment-friendly sterilizing factor. The filter disc made of the material capable of degrading the active oxygen clusters can rapidly degrade the active oxygen clusters into oxygen molecules and water molecules.

The invention relates to a washing and active oxygen cluster sterilizer for an endoscope, which is a brand-new design scheme of a washing sterilizer for a single-cavity endoscope.
Background
Endoscopic examination techniques and treatment methods are now widely used in many disciplines of clinical medicine. However, the means of washing, disinfecting and sterilizing endoscopes has been a trouble for clinicians and nurses for a long time. Because endoscopes are divided into flexible tubes and rigid tubes and various models with different sizes. Along with the development of endoscope design technology, structures with different sizes appear in a large number. However, the washing means for the endoscope is always in a state of manual washing or semi-manual washing and sterilization. Many different types of endoscope washing and sterilizing equipment are available at present, and the national standard of 'sanitation requirement of endoscope automatic cleaning machine' is issued, but the marketed endoscope automatic cleaning machine does not seem to meet the satisfaction of clinicians and nurses, so most hospitals still have a semi-manual state for washing and sterilizing the endoscope. The reason for this is that, in addition to the manufacturing technique of the device, there is a concern about sterilization and disinfection of the endoscope. Since the use of chemical disinfectants for sterilization has been largely banned from contamination of the body and the environment. Currently, disinfection is mainly performed by electrolyzed oxidizing water and hydrogen peroxide. Both the two sterilization technologies belong to low-temperature sterilization technologies, but the difficulty of having a washing function on the same equipment due to the adoption of plasma hydrogen peroxide sterilization exists. The use of electrolyzed oxidizing water for sterilization not only has the trouble of having a washing function on the same equipment, but also has the trouble of being worried about by clinical medical care personnel because the disinfection and sterilization are not thorough due to poor stability of the electrolyzed oxidizing water. Therefore, a more efficient and environment-friendly low-temperature disinfection technology is applied to the field of design and manufacture of washing, disinfecting and sterilizing integrated machines of endoscopes at present.
If the sterilization technology is divided according to the temperature, the sterilization technology is divided into a high-temperature sterilization technology and a low-temperature sterilization technology. Wherein the temperature division line is divided at about 60 ℃. The temperature during the sterilization operation is higher than 60 ℃, and the high-temperature sterilization technical category can be basically divided. On the contrary, the killing operation below 60 ℃ can be classified into the low-temperature killing technical category. Since high temperatures are undesirable for most sterilization requirements, the trend in the development of sterilization technology is to attempt to find new technological breakthroughs in the field of low temperature sterilization.
The third generation low temperature disinfection technology of xenon excimer light source capable of emitting 172nm vacuum ultraviolet shows its excellent quality. Vacuum ultraviolet rays of 172nm have radiation energy of 167kcal/mol, and can cut double bonds of oxygen molecules in the air to excite ground state oxygen (O), and can also cut hydrogen-oxygen bonds of water molecules in the air to excite ground state hydroxyl groups (HO ·), also called hydroxyl radicals. Both of which have very strong oxidizing propertiesUnder the condition of equivalent molar weight, the organic matter can be instantaneously converted into the inorganic matter CO 2 ↓ H and H 2 O ≈ ≈ O ≈ er. Since the double bond of nitrogen in air has a bond energy of 225kcal/mol and the double bond of nitrogen cannot be cut by irradiation with light of 172nm, nitrogen atoms do not participate in the photochemical reaction of air irradiated at 172nm, and therefore nitrogen oxide (NOx) does not grow unlike air discharge, and nitric acid mist is not formed. In the technical prejudice that the generation of air discharge is not in accordance with the objective facts, some technical rules and textbooks classify the photochemical products after the air is irradiated by ultraviolet light and the electrochemical products after the air is discharged into ozone (O) 3 ) Such a material having no trioxane structure exists, so that some research documents refer to a photochemical product after irradiating air with a vacuum of 172nm as "the purest ozone" according to the limitation of the prior art regulation. Vacuum ultraviolet rays of 172nm have made an outstanding contribution in the field of industrial cleaning. For example, in the current manufacture of liquid crystal panels, 172nm vacuum ultraviolet light is used to clean plasticizers, instantaneously oxidizing them to CO 2 ↓ [ sic ] and H 2 O ≈ ≈ O ≈ er. Successful use of 172nm vacuum ultraviolet light emitted by xenon excimer molecules in the industrial cleaning field has been perfectly explained and verified that 172nm narrow-band vacuum ultraviolet light necessarily has outstanding characteristics in the disinfection field.
Since the vacuum ultraviolet ray of 172nm has a weak penetration ability, the distance from the xenon excimer lamp to the surface of the object to be cleaned should be controlled within a distance range of 4mm in industrial cleaning. The existing analysis and detection research proves that the service life of the ground state oxygen and the ground state hydroxyl is in ns time level, is very short, and can rapidly form OH with oxygen and water molecules in the air - (H 2 O) n (hydrated hydroxide ion cluster), O 3 - (H 2 O) n (hydrated trioxane ion cluster), O 2 - (H 2 O) n (hydrated superoxide ion cluster) and HCO 3 - (H 2 O) n (hydrated bicarbonate ion clusters) and CO 3 - (H 2 O) n And (hydrated carbonate ion cluster). We will get us toThese terminal molecular ion clusters formed by the photochemical products of the Vacuum Ultraviolet (VUV) radiation of air are referred to as "reactive oxygen species". The oxidizing properties of the reactive oxygen species are only slightly lower than the ground state oxygen and hydroxyl radicals, but the life cycle is in the order of ms. Under the condition of equivalent molar dose, macromolecular organic matters can be degraded into micromolecular organic matters or even inorganic matters CO 2 ↓ [ sic ] and H 2 O ≈ ≈ O ≈ er. In the lung cancer cell nucleic acid clearance test using reactive oxygen species, no nucleic acid blots were detected after 24 amplifications after killing. Because the xenon excimer light source can stably and accurately release the sterilization factor 'active oxygen cluster', the concentration limit value (0.1 mg/m) of ozone is regulated according to the prior art and a class of environmental standards 3 ) The safety standard of (2) controls the concentration of active oxygen clusters in the air, and under the absolute safety concentration, the active oxygen clusters can kill natural bacteria in the air by 96% within a time less than 4 h. The result of the sterilization experiment proves that the xenon excimer light source low-temperature sterilization technology can perform sterilization operation under the condition of co-location of man and machine.
Any national and governmental technical regulation has drawbacks that lag behind the development of new technology. For example, GB28232-2020 ozone disinfector sanitary requirement issued in China refers to that electrochemical products after air ionization, photochemical products after ultraviolet light radiation and electrochemical products after water electrolysis are collectively called ozone, which is a technical lag that does not conform to objective facts. Because of the molecular formula of trioxane 3 The ozone does not exist in nature, and the main component of the terminal molecular ion cluster of the electrochemical product after air ionization is nitrate ion cluster hydrate (NO) 3 - (H 2 O) n ) Ultraviolet light required for irradiating air must be vacuum ultraviolet light (VUV) having a wavelength shorter than 200nm, and the terminal ion molecular clusters of the photochemical products thereof are reactive oxygen clusters. The water electrolysis electrolytic cell comprises two electrolytic cells, namely a diaphragm electrolytic cell and a non-diaphragm electrolytic cell, wherein the products of the electrolysis of the diaphragm electrolytic cell are hydrogen and oxygen, and the products of the electrolysis of the non-diaphragm electrolytic cell are brown gas. Nitrate ion hydrate cluster, active oxygen cluster, hydrogen, oxygen and brown gasMeanwhile, the physical and chemical properties are greatly different, and when the composition is applied to the field of disinfection and medical treatment, some characteristics are mutually communicated, some characteristics are greatly different, and particularly, the composition has great difference in safety and effectiveness. Therefore, products after air ionization, ultraviolet radiation and water electrolysis are classified in the technical regulation of GB28232-2020 ozone disinfector sanitary requirement for technical management, and errors of imprecise technical definition and inconformity with objective facts exist. This is because there is a serious standard technology behind the practical technology development in establishing the standard, which is a technical regulation that urgently needs to perform standard technology upgrade. However, the technical regulation that has been issued, regardless of the technical level, has an effective legal status from the viewpoint of technical management as long as it is not abolished, and must be performed in accordance with the existing technical regulation when expressing the technology and registering the products. So in the course of the present inventor's research on xenon excimer low-temperature sterilization technology, the name "xenon excimer ozone" and "reactive oxygen species" was used in the present inventor's technical team, and the present inventor reiterates here that the meaning of "xenon excimer ozone" and "reactive oxygen species" is the same in the patent application documents that the present inventor has filed and subsequently filed.
To sum up, the third generation low temperature disinfection and killing technology of 172nmVUV (vacuum ultraviolet) emitted by xenon excimer completely meets the comprehensive requirements of high efficiency, environmental protection and safety (taking the co-location of man and machine as the standard). In the face of such excellent low-temperature killing technology, it is a significant technical work to perfect the application technology. The applicant's technical team has carried some research work around xenon excimer low temperature killing technology and has submitted information such as: the ozone disinfection device comprises a concentrated transmission type xenon excimer light source ozone generator, an ozone spraying framework of the concentrated transmission type dielectric barrier discharge ozone generator, a pulse disinfection method and equipment for preparing ozone by using a xenon excimer light source, a method and equipment for disinfecting a microorganism incubator by using xenon excimer ozone, a pulse disinfection and food washing method by using ozone generated by excitation of the xenon excimer light source and other patent applications. In these application research works, the applicant's technical team is constantly exploring to obtain some new application technologies and have new features. Aiming at the design of a novel endoscope washing, disinfecting and sterilizing integrated machine, the technical group of the inventor skillfully applies the combination of a spear and a shield, namely a xenon excimer light source low-temperature disinfection technology and an active oxygen cluster filter digestion technology, to the application of the endoscope washing, disinfecting and sterilizing integrated machine, combines the traditional technology combination of spray nozzle rinsing, ultrasonic cleaning and the like, and provides the patent application of the washing and active oxygen cluster sterilizer of the endoscope.

Then the endoscope which needs to be washed and sterilized is put on the support rod (13) of the sterilizer inner container (6) and is firmly buckled by the endoscope fixing buckle (15). If the endoscope has an internal control needing to be washed, the internal control opening needing to be washed is opposite to the liquid movable nozzle (22) and is firmly buckled by the internal control opening fixing buckle (15), and then the inner container (6) is closed by the inner container cover (19).

And at a proper time after the washing and leaching are started, the electromagnetic valve (H1) is opened according to the set time, and meanwhile, the water suction pump (M4) is started to pump out the washing water in the liner, and the washing water is filtered by the wastewater filter assembly (8) and then is discharged out of the equipment.
3. The method comprises the following steps: the purpose of the primary rinsing with tap water is to perform a primary washing of the endoscope with tap water of a suitable temperature, removing the surface contaminants that can be washed away.
The enzyme detergent is rinsed, soaked, stirred and washed or ultrasonically washed: 1. the rinsing link of the enzyme detergent: the electromagnetic valve (H4) is switched on, the enzyme detergent is supplied to the water supply pump (M5) from the port F, and is rinsed and washed by the endoscope under the action of the water supply pump (M5) through the liquid fixed nozzle (18) and the liquid movable nozzle (22), and the PTF instantaneous heater (9) works to heat the enzyme detergent according to the set temperature. After the enzymatic detergent rinsing link is finished, whether the enzymatic detergent is soaked and stirred for washing or not can be selected according to requirements. If soaking, stirring and washing are not adopted, the electromagnetic valve (H1) can be opened according to set time, and meanwhile, the water suction pump (M4) is started to pump out washing waste liquid in the liner, filter the washing waste liquid through the waste water filter assembly (8), and discharge the washing waste liquid out of the device. 2. Soaking, stirring and washing links of the enzyme detergent: the soaking and stirring time is set in advance, if the enzyme detergent is selected to be soaked, stirred and washed, tap water is supplemented from a port D (the electromagnetic valve H4 is closed, the electromagnetic valve H2 is switched on) to a proper water level (the endoscope is immersed completely under the general condition) as appropriate after the enzyme detergent is rinsed and washed, the stirring paddle driving motor (M3) is started, and the endoscope is soaked, stirred and washed within the set time; if ultrasonic washing is not adopted, the electromagnetic valve (H1) can be opened according to set time, and the water suction pump (M4) is started to pump out the washing waste liquid in the liner, filter the washing waste liquid by the waste water filter assembly (8) and discharge the washing waste liquid out of the device. 3. Ultrasonic washing step in the enzyme detergent state: the ultrasonic oscillation washing time is set, the ultrasonic head (14) is electrified to work, and the endoscope is subjected to ultrasonic oscillation washing within the set time. After ultrasonic washing is finished, the electromagnetic valve (H1) is opened, and meanwhile, the water suction pump (M4) is started to pump out washing waste liquid in the inner container, filter the washing waste liquid through the waste water filter assembly (8), and discharge the washing waste liquid out of the device.

The inner container is completely closed, the washing part is in a silent state, the gas electromagnetic valves J1, J3, J4 and J6 are opened, then the fan (M1) is started, the xenon excimer lamp tube (2) is lightened to form inner container airflow circulation, oxygen molecules and water molecules in the airflow are excited into active oxygen clusters when the airflow passes through the xenon excimer active oxygen cluster excitation cabin, the active oxygen cluster concentration in the inner container rapidly rises along with the prolonging of circulation thickening time, and the endoscope is disinfected and sterilized by high-concentration active oxygen clusters. After the cyclic thickening time is reached, the xenon excimer lamp tube (2) is extinguished, the fan (M1) is closed, the airflow electromagnetic valve (J1, J3 and J6) is closed, the airflow electromagnetic valve (J5) is opened, the air pump (M2) is started to begin to pump negative pressure to the inner container, and high-concentration active oxygen clusters which are pumped negative pressure are degraded into oxygen molecules and water molecules through the active oxygen cluster digestion filter assembly (4) and are discharged out of the equipment through the port (A). Since oxygen molecules and water molecules are discharged, no pollution is generated to the surroundings. The purpose of pumping negative pressure when the inner container is in a high-concentration state of the active oxygen cluster killing factor is to enable the high-concentration active oxygen cluster killing factor to permeate into the micro slit spaces of the endoscope so as to effectively oxidize and kill the micro slit spaces. After the negative pressure state of the inner container is reached, the air flow electromagnetic valves (J4, J5) and the air pump (M2) are closed, the inner container is completely sealed to maintain the negative pressure state until the negative pressure maintaining time is over, and the next active oxygen cluster sterilization link is carried out until the set circulating sterilization times are reached.

After the pure water leaching and washing link is started, the electromagnetic valve (H1) can be opened according to set time, and meanwhile, the water suction pump (M4) is started to pump out washing waste liquid in the inner container and discharge the washing waste liquid out of the equipment after being filtered by the waste water filter assembly (8).
And (3) a purified airflow drying link: after the purified water washing and flushing are finished, the electromagnetic valves J1, J2, J3, J4 and J5 are opened, the fan (M1) and the air pump (M2) are started, external air is filtered from the port C through the air micro-dust filter assembly (3) in the state, airflow flowing is carried out through the air electromagnetic valves (J2, J3, J1, J4 and J5) and the inner container (6) under the interaction of the fan (M1) and the air pump (M2), and water vapor in the inner container and water vapor on the endoscope are wrapped and are discharged from the port A through the active oxygen cluster filter assembly (4), so that the washed and disinfected endoscope is dried. In practice, a heating device can be added at the port C, so that the drying air flow has an adjustable temperature of 20-50 ℃, and the drying speed can be greatly improved. The heater at the C-port is not depicted due to drawing limitations, but is specific technical details that may be contemplated by one skilled in the art.
A terminal disinfection and sterilization link (can also be designed as an automatic disinfection and sterilization program inside equipment): the lighting and extinguishing time, the circulating thickening time, the negative pressure of the inner container, the negative pressure maintaining time, the circulating sterilization times and the active oxygen cluster discharging time of the xenon excimer light source lamp tube are set in advance. The inner container is completely closed, the washing part is in a silent state, the gas electromagnetic valves J1, J3, J4 and J6 are opened, then the fan (M1) is started, the xenon excimer lamp tube (2) is lightened to form inner container airflow circulation, oxygen molecules and water molecules in the airflow are excited into active oxygen clusters when the airflow passes through the xenon excimer active oxygen cluster excitation cabin, the active oxygen cluster concentration in the inner container rapidly rises along with the prolonging of circulation thickening time, and the endoscope is disinfected and sterilized by high-concentration active oxygen clusters.

Since oxygen molecules and water molecules are discharged, no pollution is generated to the surroundings. The purpose of pumping negative pressure when the inner container is in a high-concentration state of the active oxygen cluster killing factor is to enable the high-concentration active oxygen cluster killing factor to permeate into the micro slit spaces of the endoscope so as to effectively oxidize and kill the micro slit spaces.
