本発明はチヤンバー内に収納せしめた医療用器
具を高温高圧蒸気で滅菌せしめる蒸気滅菌器に関
するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a steam sterilizer for sterilizing medical instruments housed in a chamber using high-temperature, high-pressure steam.
此種蒸気滅菌器はチヤンバー内に所定量の水を
注水し、該水を加熱沸騰せしめてチヤンバー内に
高温高圧蒸気を充満せしめこれにより被滅菌物を
滅菌消毒するものであり、斯る注水から滅菌終了
までの滅菌工程は自動的に行なうようになされて
いる。 This type of steam sterilizer injects a predetermined amount of water into the chamber, heats the water to boiling, fills the chamber with high-temperature, high-pressure steam, and sterilizes the object to be sterilized. The sterilization process up to the end of sterilization is automatically performed.
そして注水量の設定はチヤンバー内底部に配設

り注水弁を自動的に閉路せしめるようにし、又蒸
気発生は前記注水弁が閉路されたことにより加熱
ヒーターを自動的に通電せしめ貯留せる水を加熱
沸騰せしめるようにしている。 The amount of water injected is set by automatically closing the water injection valve when a water level detection rod placed at the bottom of the chamber comes into contact with the injected water, and steam generation occurs when the water injection valve is closed. The heater is automatically energized to heat and boil the stored water.

があつた。 However, if a conductive object to be sterilized (tweezers, syringe needle) is accidentally dropped into the chamber and caught on the water level detection rod, causing a short circuit between the chamber and the chamber, the object will heat up before the specified amount of water is injected. When the heater started to turn on, it caused the heater to run dry, causing various parts to burn out. Or, due to long-term use, water scale etc. may adhere to the water level detection rod, and if the rod is used as is, capillary phenomenon will occur on the surface of the water level detection rod, and the heating heater may start energizing before the specified amount of water is injected. Similarly, burnout accidents also occurred.

Reference numeral 1 denotes a chamber with an opening/closing lid 2 attached to one side, and an object to be sterilized (not shown) is placed at the inner bottom of the chamber. Shelf member 3 for storage and placement
A heating heater 4 for steam generation is provided at the inner bottom of the container.

弁７を自動閉路するようになされている。 Reference numeral 5 denotes a water storage tank for storing water to be injected into the chamber 1, and the water storage tank and the chamber 1 are connected through a water supply and drainage pipe 6, and an on-off valve 7 consisting of a solenoid valve or the like is interposed in the middle of the water supply and drainage pipe. By opening the on-off valve 7 with a start button (not shown), the water stored in the water storage tank 5 is made to flow in sequentially due to the difference in head. 8
is a water level detection device attached to the bottom of the chamber 1, which automatically closes the on-off valve 7 provided in the water supply and drainage pipe 6 by detecting a predetermined water level poured into the chamber 1.

とを知らせ修理保全等を促すものである。 Figure 2 is an explanatory diagram showing the water injection process of such a sterilizer, in which the on-off valve B is opened by the start signal A to start water injection.
Then, the water injection timer C is started, and the time until the water level detection signal D is input is measured by the water injection timer C, and if the measured time is longer than the time preset by the water injection timer C, the normality confirmation circuit E is determined to be normal. The on-off valve F is closed and the next heating circuit I is activated. Also, if the time until the water level detection signal D is input is shorter than the preset time of the water injection timer C, there is an abnormal condition in which the predetermined amount of water has not been poured, so in this case, the abnormality confirmation circuit G
This closes the on-off valve F and simultaneously activates the abnormality display circuit H to inform the user of the abnormal condition and prompt him to carry out repairs and maintenance.

れる。 As described above, the steam sterilizer of the present invention automatically injects a predetermined amount of water into a chamber that houses objects to be sterilized, heats the injected water to boiling, and uses high-pressure steam generated in the chamber to sterilize the object. In an automatic steam sterilizer that sterilizes and sterilizes objects, if the water level detection device is activated within a set time from the start of automatic water injection, an abnormality is displayed, so dry cooking as in the case of the conventional method does not occur. You can obtain a steam sterilizer that is safe and easy to handle.
