Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a medical sterilizer for sterilizing medical instruments.

[0002]

[Prior Art]

 Generally, sterilizers in the medical field are those that sterilize medical instruments such as surgical tools and dental tools using steam or ethylene oxide gas, etc. The bacteria adhering to the medical device are sterilized by making the atmosphere of steam or ethylene oxide gas.

[0003]

[Problems to be solved by the device]

 By the way, in the above-mentioned sterilization device, since the medical device is cleaned by the cleaning device and then sterilized, the workability is poor. In addition, sterilization with steam requires a large amount of equipment and cannot sterilize instruments that are sensitive to heat. With ethylene oxide gas, the gas itself is toxic and harmful to the human body. ..

Therefore, the present invention has been made in consideration of such circumstances, and an object thereof is to provide a medical sterilizer having good workability and easy handling.

[0005]

[Means for Solving the Problems]

 In order to achieve the above object, the medical sterilizer of the present invention comprises a container for storing a medical instrument to be sterilized, a container provided with the container, and washing water is sprayed onto the medical instrument for cleaning, and then an ozone water is used. And a spray nozzle for spraying and sterilizing.

[0006]

[Action]

 Cleaning water is sprayed from the spray nozzle to the medical device to wash the medical device, and then ozone water is sprayed to sterilize the medical device. The ozone has been proved to have a sterilizing effect in foods, pools, sewage treatment, etc., so that it can sterilize medical equipment sufficiently, and it decomposes in a short time, so it is safer than ethylene oxide gas. There is also a property, it can be handled easily. Therefore, since the medical device can be washed and sterilized without moving the medical device, it is possible to provide a sterilizer having good workability and easy handling.

【Example】

 An embodiment of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, reference numeral 1 denotes a container for storing a medical instrument 2 such as a surgical tool or a dental tool to be sterilized. An ozone killer 3 is connected to the container 1 and is generated in the container 1. The generated gas (ozone gas) is collected by the ozone killer 3 to prevent the ozone gas from leaking to the atmosphere.

A storage net 4 for storing the medical device 2 is provided below the container 1, and a net 5 is provided below the storage net 4. Further, at the lower part of the container 1, two first and second discharge pipes 6 and 7 for discharging the liquid accumulated in the container 1 are connected, and these discharge pipes 6 and 7 are respectively provided with a first pipe. First and second control valves 8 and 9 are provided. Further, above the inside of the container 1, a jet nozzle 10 for jetting washing water and ozone water toward the medical instrument 2 on the storage net 4 is rotatably provided. A conduit 11 for supplying a liquid is connected to the injection nozzle 10, and a water supply pipe 13 having a third control valve 12 for supplying tap water as washing water is connected to the conduit 11. In addition to being connected, an ozone water supply pipe 15 having a fourth control valve 14 for supplying ozone water is connected.

The ozone water supply pipe 15 is connected to an ozone water producing apparatus 17 via a pump 16, and the ozone water producing apparatus 17 is configured so that the liquid in the container 1 is guided to the ozone water producing apparatus 17. The second discharge pipe 7 is connected. The ozone water producing apparatus 17 is connected to an ozone generating apparatus 18, and is configured such that ozone from the ozone generating apparatus 18 produces ozone water having an ozone concentration of 1 ppm or more. Is supplied to the container 1 via the ozone water supply pipe 15 by the pump 16.

An operating portion 19 is connected to the fourth control valve 14 of the ozone water supply pipe 15 and the first, second and third control valves 8, 9, 12 described above. This operation unit 19 controls the valves so that the first control valve 8 and the third control valve 12 are opened and the second control valve 9 and the fourth control valve 14 are closed when the medical device 2 is washed. In addition, when sterilizing the medical device 2 after cleaning, the first control valve 8 and the third control valve 12 are closed and the second control valve 9 and the fourth control valve 14 are opened. Thus, such control can be performed automatically or manually.

In addition, an indoor gas monitor 20 is installed in the room in which the container 1 is installed, just in case ozone gas leaks into the room.

When sterilizing the medical instrument 2 such as a surgical tool or a dental tool, the medical instrument 2 is stored in the storage network 4 in the container 1, and the control valve 8 is operated via the operation section 19. , 9, 12, 14 are operated.

Then, the first control valve 8 and the third control valve 12 are controlled to be opened, and the second control valve 9 and the fourth control valve 14 are controlled to be closed. As a result, tap water is sprayed from the spray nozzle 10 toward the medical device 2 through the water supply pipe 13 and the conduit 11, and the medical device 2 is washed. The water used to wash the medical device 2 is drained from the first discharge pipe 6.

When the cleaning of the medical device 2 is completed, the first control valve 8 and the third control valve 12 are closed, and the second control valve 9 and the fourth control valve 14 are controlled to be open. As a result, ozone water having an ozone concentration of, for example, 1 ppm or more produced by the ozone water producing apparatus 17 is supplied to the injection nozzle 10 by the pump 16 via the ozone water supply pipe 15 and the conduit 11. Ozone water is jetted from the nozzle 10 toward the medical device 2, and the bacteria adhering to the medical device 2 are sterilized by the ozone water, and the medical device 2 is sterilized. The ozone has been proved to have a bactericidal effect in foods, pools, sewage treatment, etc. In addition to being capable of decomposing in a short time, it is safer than ethylene oxide gas and easy to handle.

Water that has sterilized the medical device 2 enters the second discharge pipe 7 from the lower part of the container 1 and is guided to the ozone water producing apparatus 17 to be reused.

Therefore, by providing the container 1 with the injection nozzle 10 for ejecting the liquid toward the medical device 2 stored in the container 1, the first, second, third and fourth control valves 8 are provided. , 9, 12, and 14 are operated, the tap water and the ozone water are jetted toward the medical instrument 2 from the jet nozzle 10 so that the medical instrument 2 can be cleaned without moving the medical instrument 2. Sterilization is possible, workability is improved, and the device can be handled easily.
