The present invention relates to a medical sterilization apparatus having a level sensor, and more particularly, to an apparatus for sterilizing a tool (sterilized substrate) used for medical treatment or surgery.

In general, medical tools used for patients in hospitals, etc. must have a procedure for sterilization and reuse after one use. To this end, devices for sterilizing medical instruments have been developed and have been continuously improved.

On the other hand, as a technology related to the medical sterilization apparatus related to the present invention, Republic of Korea Utility Model Publication No. 0123317 (designation: medical sterilizer), Republic of Korea Registered Utility Model Publication No. 20-0263242 (designation: Sterilization room structure of automatic sterilizer), Registration No. Korea Patent Publication No. 0164023 (Invention: Spray sterilization apparatus and sterilization method), Republic of Korea Patent Publication No. 2002-0013351 (Invention: Medical name) Instrument sterilization cleaning device), Publication No. 10-2004-0071708 (Invention name: High pressure steam sterilization system and sterilization device and sterilization method for medical devices), Republic of Korea Patent Publication No. 10-0365705 (Invention name: Medical use) Water supply by vacuum and hot water of a small autoclave).

Such a conventional medical sterilization device is a method for sterilizing a sterilized substrate by steam by placing the sterilized substrate in a sterilization chamber, supplying distilled water stored in the reservoir to the sterilization chamber, and then operating a heater to generate steam. I'm using.

In this case, if the amount of distilled water supplied to the sterilization chamber is excessive, the time according to the actual sterilization operation may be excessive or insufficient sterilization may be performed. If the amount of distilled water is too short, the sterilized substrate may be damaged due to the rapid evaporation of the distilled water. Since there is a problem such as heat deformation occurs, supplying an appropriate amount of distilled water is one of the important factors. Therefore, the amount of distilled water to be supplied to the sterilization chamber should be an appropriate amount. In the past, a method of controlling the amount of distilled water by checking the amount of distilled water leaving the supply time of distilled water or the reservoir has been used. The reason for using this method is that distilled water is an electrical insulating material unlike ordinary drinking water or ionized water, and thus it is difficult to detect the level of distilled water by electrical sensing.

However, according to the method of adjusting the supply amount of distilled water by checking the supply time of distilled water, problems such as a supply line supplied from the reservoir to the sterilization chamber are often blocked. There was a problem that caused the substrate to be damaged, and the method of controlling the amount of distilled water by checking the amount of distilled water flowing out of the reservoir, the amount of distilled water drained because the amount of distilled water stored in the reservoir is not always constant. Not only was it difficult to measure accurately, but there was a hassle of supplying distilled water while checking the water level of the reservoir each time.
