Description

Invasive medical equipment cleaning, disinfecting and sterilizing device

Technical Field

The invention relates to the technical field of medical equipment and microorganisms, in particular to an invasive cleaning, disinfecting and sterilizing device for medical equipment.

Background

The most common and effective method for sterilizing medical equipment in medical institutions at present is high-temperature sterilization, but is limited by the limitations that many advanced precise medical instruments and invasive medical equipment are not high-temperature resistant, high-temperature sterilization cannot be used, and when low-temperature sterilization is used, the equipment cannot be guaranteed to reach strict sterilization standards, so that severe infection and death cases in the world are caused, and the like, so that the conventional sterilization technology cannot ensure that pollutants and bacteria and viruses of the medical equipment used in the medical process are completely removed and killed, so that the patients are infected interactively in the subsequent medical process, and the life and property loss is caused.

The Decontamination (Decontamination) called in the medical field includes disinfection and sterilization, and generally aims at the regulation of various invasive medical devices (a), and most of them are required to reach the disinfection level, however, for many thermolabile devices with complex structure, such as expensive endoscope, etc., when they cannot be treated by the common high temperature disinfection method, the high grade disinfection (> 99.9999%) is also an acceptable alternative for the regulation.

In addition to high temperature sterilization, the common alternative sterilization method is more effective in EO (ethylene oxide) sterilization, which is mainly used for constructing simple heat-labile medical equipment in medical institutions. The current International agency for research on cancer (IARC) has listed EO as the first-order carcinogen, and exposure to this chemical may also cause symptoms such as nausea, vomiting, skin burns or pulmonary edema. In addition, EO has been shown to cause abortion and fetal abnormalities, or to increase mortality in patients with gastric cancer, leukemia, and circulatory diseases. The main exposer in a hospital is the person operating the EO disinfection machine in the disinfection room. In addition, it is possible that the sterilized equipment is exposed to residual equipment and gradually releases ethylene oxide. Also, if a separate ventilation and exhaust device is not designed at the location of the EO disinfection machine, the EO's sinking characteristics may be left in the workplace, causing exposure to many people. Internationally, alternative sterilization methods are actively sought in response to the potential hazards ethylene oxide poses to users.

Although there are currently available low-temperature sterilization techniques such as ion beam Radiation sterilization (ioning Radiation), Gas Plasma (Gas Plasma), and chemical methods such as Vapor phase hydrogen Peroxide (Vapor phase hydrogen Peroxide), Ozone (Ozone), glacial acetic acid (Peracetic acid), and glutaraldehyde (glutaraldehyde), ethylene oxide sterilization is the most commonly used method in consideration of economic cost, sterilization effect, and the kind of applicable articles.

For many heat-labile devices with complicated structure, such as expensive endoscopes, the currently used low-temperature sterilization technique mainly uses liquid reaction, such as glacial acetic acid (Peracetic acid) or glutaraldehyde (glutaraldehyde), to soak the endoscope for a period of time, and washes the endoscope tube through the above-mentioned chemical circulation to achieve the purpose of contacting and killing bacteria and virus. However, the problem commonly encountered in the international medical field is that the expensive endoscope generally has a complicated design, so that the virus adhered to the pores, pipes and joints can not be completely eliminated by the chemical agent washing, even many drug-resistant bacterial spores can enter a hibernation state in a severe environment, and once the severe environment disappears, the unremoved bacteria can recover the activity to cause the infection or death of the patient, so that the cleaning quality is poor, and the infection and death cases are smelled. In addition, the harmfulness of the timeliness of medicaments such as glutaraldehyde to the respiratory system of operators cannot be effectively controlled during operation.

Research reports published by john hopkins medical college show that the existing disinfection mode of soaking in disinfectant can not effectively and properly treat invasive medical instruments to reach high-level disinfection standards, mainly lies in many invasive medical instruments and complex designs, materials comprise plastics, optical fibers, lenses and the like, can not be treated in a high-temperature disinfection mode, the manual brushing quality is poor, a plurality of death infection complications derived from disinfection failure are caused, particularly, the poor quality of manual treatment is one of main causes of disinfection failure, other super bacteria containing drug resistance can not be killed by common disinfectants, and the like, and the problem which needs to be solved most urgently exists at present.

At present, a lot of cleaning, disinfecting and sterilizing devices are also available on the market, but the invasive medical equipment is dried by a drying method basically, and the invasive medical equipment is not high in temperature resistance, so that the used temperature is not high, the interior of the equipment is not thoroughly dried easily, germs are easy to breed, and the final cleaning and disinfecting effect is not good.

The reaction tank 10 is used for placing contaminated invasive medical equipment a, the ultrasonic generator 20 is used for desorbing tiny bacteria and viruses in pores of the invasive medical equipment a, the circulating pump mechanism 30 is used for driving disinfection and sterilization agents in the reaction tank 10 into a cavity of the invasive medical equipment a so as to transfer ultrasonic oscillation force to desorb and remove the contaminants, the oxidation reaction mechanism is used for generating oxidation in the reaction tank 10, and the chemical agent supply mechanism 50 is used for supplying disinfection and sterilization agents in the reaction tank 10.

By applying the technical scheme of the invention, the chemical agent supply mechanism 50 is used for supplying disinfection and sterilization agents into the reaction tank 10, the invasive medical equipment a is placed into the reaction tank 10 added with the disinfection and sterilization agents, and the disinfection and sterilization agents are pumped into the cavity of the invasive medical equipment a through the circulating pump mechanism 30, so that on one hand, decontamination, disinfection and sterilization can be performed on the cavity of the invasive medical equipment a, and on the other hand, the disinfection and sterilization agents can also be used for desorbing and removing pollutants by transmitting ultrasonic oscillation force. In this way, bacterial spores, viruses or pollutants attached to the surface, hollow tube, pore and crack of the endoscope or other invasive medical devices a can be rapidly and effectively desorbed and removed. In the process, the oxidation reaction mechanism is used to generate oxidation effect in the reaction tank 10, so as to oxidize, destroy and decompose the contaminant bacteria microorganism for disinfection and sterilization reaction, thereby ensuring no residual contaminant or virus exists on the surface of the invasive medical device a and even in the tiny pores inside the inner pipeline. After decontamination, disinfection, the completion of disinfecting, link to each other with invasive medical equipment a through negative pressure pipeline 61 to the dewatering of bleeding into invasive medical equipment a's inner chamber, guarantee that invasive medical equipment a's inner chamber enters into dry state, avoid moist invasive medical equipment a's inner chamber to breed the germ once more, make invasive medical equipment a preserve not receive external pollution when using next time, guarantee final disinfection effect.

Optionally, as shown in fig. 1, a water inlet valve 11 and a water discharge valve 12 are further disposed on the reaction tank 10.

Many invasive medical devices, after contacting the body, adhere to the patient with contaminants such as: body fluids, blood, germs, viruses, etc. As shown by the past experience, the adhesion of the pollutants is very strong, and if there is no proper way to remove the pollutants, it is very difficult to completely and thoroughly eliminate the pollutants, so the main purpose of using ultrasonic vibration is to effectively remove the bacterial spores, viruses or pollutants on the surface, hollow pipes, seams and cracks of various medical devices by means of the strong vibration force, so as to achieve the purpose of removing the pollutants and cleaning. Wherein, the frequency of the optional ultrasonic generator 20 is 1-200,000 KHz, preferably 1-1,000,000 KHz or 1-8,000 KHz, and the intensity is enough to shake and desorb the pollutants in the pores as small as 0.12 micron out of the invasive medical equipment a. The ultrasonic generator 20 may be disposed outside the reaction tank 10 or inside the reaction tank 10. The reaction tank 10 is filled with an aqueous solution level and should be completely above the invasive medical device a.

As an alternative embodiment, as shown in fig. 1, the drying mechanism further includes a negative pressure pump 62, and the negative pressure pump 62 is disposed at the reaction tank 10 and is used for generating negative pressure to the negative pressure pipeline 61, so as to achieve air-suction water-removal drying of the lumen of the invasive medical device a.

As a more preferable embodiment, the drying mechanism further includes an alcohol supply line 63, and the alcohol supply line 63 is provided at the reaction tank 10 for spraying alcohol onto the surface of the invasive medical device a and/or the lumen of the invasive medical device a. The alcohol is sprayed to the inner cavity of the surface of the invasive medical device a through the alcohol supply pipeline 63, so that on one hand, the sterilization and disinfection effects can be achieved, on the other hand, the drying effect of the invasive medical device a can be accelerated, and the subsequent use is facilitated. Alternatively, as shown in fig. 1, the drying mechanism further includes an alcohol tank 64, and the alcohol tank 64 is disposed at the reaction tank 10, connected to the alcohol supply line 63, and supplies alcohol to the alcohol supply line 63. Optionally, the alcohol supply line 63 may spray alcohol to the lumen of the invasive medical device a by using the negative pressure line 61 when spraying alcohol to the lumen of the invasive medical device a.

As shown in fig. 1, in the present embodiment, the oxidation reaction mechanism includes an ozone generator 41 and an aeration pipe 42, the ozone generator 41 is used for generating ozone, and the aeration pipe 42 is disposed in the reaction tank 10 and connected to the ozone generator 41 for supplying the ozone generated in the ozone generator 41 to the reaction tank 10. When the ozone generating device is used, air or pure oxygen can be reacted by the ozone generator 41 to generate high-concentration ozone, the high-concentration ozone and the water solution are introduced into the reaction tank 10 through the aeration pipe 42, saturated ozone water (oxygenated water) is formed by fully mixing the high-concentration ozone and the water solution, after pollutants desorbed by ultrasonic waves are contacted with the saturated ozone in the water solution, oxidation destruction decomposition reaction is immediately carried out, the pollutants of a human body are carbohydrates, and harmless carbon dioxide and water can be formed after the pollutants are decomposed by the ozone, so that the effects of decontamination and disinfection are achieved. Preferably, in the solution of the present embodiment, the aeration pipe 42 is disposed at the bottom of the reaction tank 10 so that the ozone can be sufficiently mixed with the aqueous solution.

More preferably, as shown in fig. 1, in the solution of the present embodiment, the oxidation reaction mechanism further includes an ultraviolet lamp 43, and the ultraviolet lamp 43 is disposed at the top of the reaction tank 10 and used for irradiating the reaction tank 10. The ultraviolet ray is a powerful and cheap disinfecting tool, which can effectively eliminate bacteria or viruses, the wavelength of the ultraviolet ray of the system is 100-390 nm, the reaction tank forms a sterile state under the irradiation of the ultraviolet ray, which can prevent the bacteria and viruses in the outside air from contacting with invasive medical equipment a to cause reinfection, and the ozone can also perform photochemical catalysis reaction under the irradiation of the ultraviolet ray, accelerate the destruction and decomposition rate of pollutants, and is helpful for the disinfection and sterilization reaction. The ultraviolet lamp 43 can emit a pipeline with a wavelength of 100-390 nm, and when the ultraviolet light contacts and reacts with ozone, a photocatalytic reaction can be formed, so that the reaction rate of gaseous and liquid oxidation is greatly increased, and the residual pollutants or germs can be quickly decomposed and destroyed by the reaction. The photochemical reaction rate of the combination of the ultraviolet rays and the ozone is more than dozens to hundreds of times that of the pure ozone, so that the ultraviolet rays and the ozone can quickly react to oxidize residual pollutants or germs. By placing the invasive medical device a and the strong oxidizer disinfectant in contact with ozone in an aqueous solution, the contaminant bacteria microorganisms can be oxidatively destroyed and decomposed to perform a sterilization reaction.

More preferably, the oxidation reaction mechanism further includes a photocatalyst reactor 44, and the photocatalyst reactor 44 is disposed in the reaction tank 10 for oxidizing contaminants or germs remaining in the reaction tank 10. Thus, the organic pollutants can be decomposed and sterilized more rapidly and effectively by the combination of the ultraviolet rays, the photocatalyst and the ozone, so as to ensure that no residual pollutants or viruses exist on the surface of the invasive medical device a or even in tiny pores inside the pipeline. The supersaturated ozone gas rises to the upper part of the reaction tank 10 along with the rising of the ozone gas, and forms a sterile space with the ultraviolet rays and the photocatalyst, so as to ensure that the invasive medical equipment a is not secondarily polluted due to the transmission of the external gas and the water quality in the disinfection and sterilization process.

As shown in fig. 1, optionally, the chemical agent supply mechanism 50 includes a disinfection and sterilization agent tank 51 and an agent delivery pump 52, the disinfection and sterilization agent tank 51 is disposed adjacent to the reaction tank 10, the agent delivery pump 52 is used for supplying the disinfection and sterilization agent in the disinfection and sterilization agent tank 51 to the reaction tank 10, and the disinfection and sterilization agent tank 51 stores the disinfection and sterilization agent, and the disinfection and sterilization agent can be diluted into the reaction tank 10 to perform a reaction treatment on the contaminants, so as to ensure that the contaminants are in complete contact with the disinfection/sterilization agent and the strong oxidant, and then are damaged by oxidation. Wherein, the disinfectant can be one or a plurality of mixed disinfectants, the chemical agent can effectively kill various stubborn bacteria and viruses, and the concentration and the agent can be adjusted according to the requirement. The above-mentioned sterilants refer to one or more liquid sterilants or sterilants such as: hypochlorous acid (hydrochlorous acid), Hydrogen Peroxide (Hydrogen Peroxide), peroxyacetic acid (OPA), Hydrochloric acid (Hydrochloric acid), sodium Hypochlorite (hydrochlorite), Sulfuric acid (Sulfuric acid) and Hypochlorite (hydrochlorite) can be applied, and the operation concentration range is 10-200,000 ppm. The disinfectant and sterilizing agent used in the invention is a diluted low-concentration harmless agent, the reaction process does not cause harm to the environment and operators, the disinfectant and sterilizing agent can be directly discharged without being recycled after use, and the problem of secondary environmental pollution is avoided.

As shown in fig. 1, in the technical solution of the present embodiment, the invasive medical equipment cleaning, disinfecting and sterilizing apparatus includes a leak detection mechanism, which is disposed at the reaction tank 10 and is used for detecting whether the invasive medical equipment a is intact. The invasive medical device a with the tube lumen may be tested for leaks by a leak detection mechanism. As shown in fig. 1, the leak detection mechanism optionally includes an inflator 71, a pressure gauge 72, and a controller. The inflator 71 is used for inflating the inner cavity of the invasive medical instrument a, the pressure device 72 is used for detecting the pressure value of the inner cavity of the invasive medical instrument a, and the controller is electrically connected with the pressure device 72 and is used for receiving the pressure value measured by the pressure device 72 and determining whether the invasive medical instrument a is in good condition or not according to the comparison between the pressure value and the preset value. In use, gas may be delivered to the lumen of the invasive medical device a and the pressure value measured by the controller 72 is compared to a predetermined value, and if less than the predetermined value, a leak is indicated in the invasive medical device a. Alternatively, the controller and pressure device 72 may be used to maintain the inflation pressure of the inflator 71 against the internal cavity of the invasive medical device a, and then observe air bubbles in the water to determine that the invasive medical device a is leaking.

Optionally, as shown in fig. 1, in the technical solution of the present embodiment,

the invasive medical equipment cleaning, disinfecting and sterilizing device comprises: the activated carbon and reducing agent filter 80, the activated carbon and reducing agent filter 80 is arranged at the reaction tank and used for filtering, reducing and purifying the air of the ozone and the oxidant which are reacted in the reaction tank.
