Fig. 2 is a schematic cross-sectional view of the medical device cleaning device 1 viewed from the vicinity. The medical device cleaning device 1 further includes an ozone generating unit 16, a washing tank 17, a gas processing unit 19, a fan 21, a heater 22, and a water storage tank 23. Ozone generation The early 16 series uses air taken in by self-inhalation σ11 to generate ozone gas. The ozone generating unit 16 corresponds to an ozone gas generating unit. Further, in addition to the intake of air from the air intake port 11, it is also possible to take oxygen directly from the oxygen tank or the like. As a method of generating an ozone gas, various methods such as a silent discharge method, an electrolysis method, a photoreaction method, a high-frequency electrolysis method, and a solid polymer electrolysis method can be used. The ozone generating unit 16 is provided with a concentration meter (not shown) for controlling the concentration of the ozone gas, and is controlled so as to reach the concentration of the ozone gas suitable for the treatment. The washing tank 17 is a unit that can be placed in a medical device that needs to be cleaned. The washing tank 17 corresponds to the washing portion. The washing tank 17 can also be easily washed for the medical sub-type, the smaller shape of the f-knife, and is constructed such that the inside of the ordinary dish washing machine is made to have an inner wall having a concave-convex shape or a mesh such as a mesh. Shape 158484.doc 201212956 basket, who. The cleaning tank (4) is connected with ozone to produce the ozone gas generated from the ozone generator. The ozone gas is sent to the washing tank 17, and the medical device is washed. A concentration meter (not shown) for controlling the concentration of the ozone gas or a temperature controller (not shown) for controlling the temperature is provided in the cleaning tank. The concentration meter corresponds to the control unit. The X' washing tank 17 is connected to a water supply port 18 for supplying water for use in liquid washing. The gas treatment unit 19 is used for ozone gas treatment of medical instrument cleaning, and is discharged to the human body harmless m from the exhaust gas σ2 (). The gas processing unit 19 corresponds to a gas processing unit. That is, the gas processing unit 19 is also provided with a comminometer (not shown), and is controlled so that the ozone gas having a harmful human body concentration is not discharged to the outside. The fan 21 is disposed adjacent to the washing tank 17, and the medical device that has been liquid-washed by the fan flows dry β χ, and the heating (4) heats the circulating air of the fan 21 to the warm air ‘ Dry effectively. The water storage tank 23 temporarily stores the washing liquid used in the liquid washing step for reuse. In the liquid washing step, when the washing liquid is not dirty and can be reused according to the degree of the stain of the medical device, the washing liquid is kept in the water storage tank 23 for the next washing. Use. The water storage tank is connected to the washing tank 17 and the ozone generating unit 16, and the oxygen gas used in the washing tank 17 or the ozone gas generated in the ozone generating unit (10) is filled in the water storage tank 23' or by The ozone gas is mixed through the cleaning liquid, and is prevented from being propagated by bacteria such as bacteria in the washing liquid stored in the water storage tank 23. The excess cleaning liquid is discharged from the drain σ 24 due to washing and rinsing. 158484.doc 201212956 Fig. 3 is a view showing an example of a washing step of the medical device of the present invention. In the input step 30, the used medical device is loaded into the internal washing tank 17 from the washing tank door 12 of the medical device washing device 1. Then, in the liquid = net step 34, the obtained liquid is dissolved by a medical detergent, an inspective detergent or the like. The detergent can be manually put in together with the medical device put into the step 3, or the inside of the medical device cleaning device 1, the detergent can be stored in advance, and the flocculant can be automatically supplied when the liquid is washed. The liquid washing step dissolves the detergent in the water supplied from the water supply port 18, and washes the medical device with a washing nozzle (not shown). Alternatively, the medical device may be immersed in a liquid in which the water supplied from the water supply port 18 is supplied with a detergent, and the solution is washed and washed. Furthermore, the cleaning liquid should be warm water. Here, as described above, when the washed medical device is less contaminated, the washing liquid used in the cleaning step 31 can be reused. The used cleaning liquid is temporarily stored in the water storage tank 23 for reuse, and is used for the next washing. The washing liquid accumulated in the f water tank 23f is sent to the washing tank 17 and used in the liquid washing step 31. Since ozone gas has a bactericidal action, ozone gas can be filled in the space of the water storage tank 23, or ozone gas can be passed through the cleaning liquid to prevent the growth of fine g such as disease g. The washing water which has been dirty after being reused several times is discharged by the drain port 24. Empty storage = The tank is cleaned with tap water or ozone water, filled with ozone gas, and kept in a state of preventing bacteria from being used until the next use. Then, in the rinsing step 32, the washing liquid adhered to the medical device after the liquid washing step is washed. As long as the water supplied from the water supply port 18 is sprayed to the medical device by the flushing water jet nozzle 158484.doc -8 - 201212956 (not shown), the method of flushing the oil clearing agent; or, the water supplied, and Any method may be used for the method of rinsing the washing liquid adhered to the medical device, such as a method in which the medical device is immersed in the water for rinsing. Furthermore, the rinse water should be warm water. The water used for flushing is discharged from the drain port 24. Subsequent to the drying step 33. Here, the medical device is dried by the flow of air ' delivered by the fan 21. By using the air supplied by the fan 21, the IL blows off or evaporates water droplets on the surface of the medical device to promote drying. Further, by providing the heater 22 in the vicinity of the fan 21, the airflow of the ventilation becomes warm air, and the medical device is dried in a shorter time. Further, although the drying step 33 is not essential, in the ozone gas cleaning step 34 as the next step, when the ozone gas is brought into contact with the surface of the medical device, if excess water droplets remain, the ozone gas may not be sufficiently accessible. The medical device is so defective that it is preferred to include the step of drying step 33. Then, the medical device is washed in the ozone gas washing step 34. This step is followed by washing by the liquid washing step 31, and then washing the fine washing residue which has not been washed and remains in the fine portion of the medical device. After the liquid is washed, the ozone gas generated by the ozone generating unit 16 is filled in the washing tank 17 into which the dried medical device is placed, and the ozone gas is brought into contact with the medical device. When the liquid is washed in a thin tubular medical device such as a tubular catheter or a medical device having a complicated structure such as a tweezers or an endoscope, since the washing liquid is a liquid, the molecules are too small, and the washing liquid cannot be scattered. The narrow part, so there is the possibility of causing washing and ruin. Here, by using ozone gas, the ozone gas as a gas can be infiltrated into the narrow portion of the complicated assembly of the medical device 158484.doc 201212956, which is inaccessible to the liquid, and is washed by the detergency of ozone gas. In the liquid washing system, the self-decomposing gas is further self-decomposed in an environment of extreme high temperature or high humidity, so that the gas concentration is lowered, resulting in a decrease in the decomposition effect of the protein. On the other hand, since the protein decomposition of ozone gas is derived from the chemical reaction caused by the strong oxidation of ozone gas, the ozone gas can be activated by setting the temperature in the cleaning tank to a normal temperature or higher. To promote the reaction. Therefore, it is possible to perform more efficient cleaning by controlling the temperature in the tank to an appropriate temperature and maintaining the above-described equilibrium of self-decomposition and reaction promotion. The concentration of the ozone gas is preferably 5 to 9 v 〇 1%, and it may be adjusted according to the degree of the fouling. Further, the time for bringing the ozone gas into contact with the medical device should be 5 20 knives, but it may be appropriately adjusted according to the degree of the stain. The ozone gas system used in the ozone gas cleaning step 34 is treated by the gas treatment unit to a concentration (0.2 ppm or less) which does not affect the human body, and is then discharged from the exhaust port 2 to the outside. Further, in the ozone gas cleaning step 34, the oxygen gas may be used for washing and sterilizing the water storage tank 23. The washed medical condition is in step 35 and is removed from the cleaning tank door 12 of the medical device cleaning device. [Examples] The above-mentioned medical device cleaning device 1 was used to confirm the washing effect, and the sheep blood was applied to the medical device, and then the steps shown in Fig. 3 were used. As the cleaning solution, use G_5% of the test detergent to clean the ozone gas with an ozone gas concentration of 9 Vol% and contact the medical device for 158 484.doc 201212956 for 5 minutes. In addition, as a washing liquid, the application of the sheep blood, and the preparation of the medical device for the use of the same diarrhea blood as described above, for 5 minutes, the sputum plate is used for the money and is divided into I, and the method is measured. Residual protein of the sample. #由考马斯 Figure 4 is the residual protein of each sample to represent the amount of residual protein. At 5 8 h,,, ° ° fruit. In Fig. 4, after the vertical axis system and the knife 4 are cleaned, the residual protein in the sample exposed to ozone gas for 5 minutes is 〇, ', 钟(四) Jia is 10 or less, and when only the deduction is performed, the residue is left. The protein is l〇~2〇^ η± „ ^, when only 5 minutes of washing, the residual protein is more (10) called, less is left and right 'existing more than ttl... 5 minutes after washing, ozone gas is contacted and only When the lamp is compared for 5 minutes, there is no unevenness in the exposure to ozone gas after 5 minutes of washing. The residual protein f in all samples is below i() ,, so it can be cleaned by the cleaning liquid and ozone gas is used. In addition, it is considered that it is effective for cleaning even if ozone gas is used alone. According to the above measurement result, it is confirmed that it can be attached to the blood of medical II by washing with ozone gas. The protein is effectively removed in a short period of time. When the liquid is washed only, when a thin tubular medical device such as a tubular catheter or a complicated medical device such as a tweezers or an endoscope is washed, it is washed. Liquid can not be scattered In the narrow part, there is a possibility that sufficient washing cannot be performed. However, by using ozone gas to clean, the ozone gas as a gas can be infiltrated into the narrow portion of the complicated assembly of the medical device, so that the liquid can be washed. The washing and smashing of the narrow portion which is not completely removed in the net can be washed by combining ozone gas washing and liquid washing, and the medical device can be effectively washed in a short time. 158484.doc 201212956 The present invention does not In addition to the above-described embodiments, various modifications can be considered without departing from the spirit of the invention. For example, in the above embodiment, the pure gas is recorded after the liquid is washed, but in the case, the liquid is washed with ozone gas. In the case of washing, the ozone gas can be shortened, and the ozone gas can be washed first, and then the liquid is first cleaned. When the ozone gas is first cleaned, The knives of the protein become smaller, so that the time for liquid washing can be shortened. The present invention can be implemented in various other forms without departing from the spirit or main features. The scope of the invention is not limited by the scope of the invention, and the scope of the invention is not limited by the scope of the specification, and further variations or modifications of the scope of the invention are within the scope of the invention.
