DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an autoclave device, and more particularly, to an autoclave device for sterilizing various tools and auxiliary tools frequently used in dental treatment and the like.

[0002]

2. Description of the Related Art In dental treatment, various instruments, for example, a turbine handpiece, a contra-shank handpiece, a multi-syringe, an ultrasonic scaler, etc., are used for each patient from the viewpoint of hygiene. It is preferable to use a sterilized one. For this reason, an autoclave device (a high-pressure steam sterilizer) has been prepared in each clinic, and these instruments are generally sterilized before starting medical treatment, and sterilized for each patient. I try to use instruments.

FIG. 2 is a view for explaining an example of a conventional autoclave apparatus. FIG. 2 (A) shows a state in which the open / close lid is closed, and FIG. 2 (B) shows a state in which the open / close lid is opened. Middle one
Reference numeral 0 denotes a casing main body (autoclave apparatus main body), and reference numeral 1 denotes an opening / closing lid thereof. In use, as is well known, the open / close lid 1 is opened, and after the instrument to be sterilized is put in the chamber 2 of the autoclave apparatus main body 10,
The opening / closing lid 1 is closed, and is locked by a lock mechanism 3 so that the opening / closing lid 1 is not opened by the vapor pressure in the chamber 2. Water is injected into the chamber 2 from the water injection lid 4. When a drive switch on the operation panel 5 is pressed, the heater in the chamber 2 heats the water in the chamber 2, and steam is generated in the chamber 2. And then reach a high pressure over time.

[0004] As described above, the interior of the chamber 2 is set to high-pressure steam, and the inside of the chamber is maintained at the high-pressure steam for a predetermined time to sterilize instruments and the like.
The instruments and the like are taken out of the chamber 2.
Since the high-pressure steam is filled, if the lid 1 is opened immediately after the end of the sterilization, the steam is blown out, which is dangerous.

[0005] Therefore, usually, it is confirmed by a pressure gauge that the steam temperature in the chamber is reduced by natural cooling and the pressure in the chamber is reduced to a pressure at which steam is not ejected, and then the lid 1 is checked.
The lid 1 is prevented from opening unless the pressure in the chamber is reduced to a pressure at which no steam is blown out or the pressure at which no steam is jetted out.

[0006] However, when the temperature in the chamber is lowered by cooling the chamber, water droplets are generated in the chamber. If the water droplets adhere to the object to be sterilized, the water is removed when the object to be sterilized is taken out and used. Water drops must be removed. Therefore, after the end of the autoclave, hot air is fed into the chamber to dry the inside of the chamber.

[0007]

On the other hand, generally, as shown in FIG. 3A, a plurality of objects to be sterilized are placed on the tray 6 or as shown in FIG. As shown in (B), it is autoclaved collectively by putting it in a heat-resistant bag 7 or the like. However, when put in a bag, as described above, even if hot air is sent into the chamber, It is difficult to remove water droplets attached to the material to be sterilized in the bag, and after all, the water droplets attached to the material to be sterilized must be removed after being taken out of the bag, and the effect of supplying dry air is reduced by half. Will be done. The present invention has been made in view of the above circumstances, and particularly in a case where an object to be sterilized is put in a bag and autoclaved, to prevent water droplets from adhering to the object to be sterilized after completion of the autoclave. It was made for the purpose of.

[0008]

According to the present invention, in order to solve the above-mentioned problems, an object to be sterilized is housed and sealed, and at the same time, water inside is heated by a heater to generate high-temperature and high-pressure steam. In an autoclave device for autoclaving the object to be sterilized, and after autoclaving, supplying hot air to dry the object to be sterilized , far-infrared light is introduced into the autoclave device.
A line heater, and the far-infrared heater allows the
By irradiating far infrared to the bag object it is housed, and the object to be sterilized in the bag is heated from the outside bag is characterized in that so as to remove water droplets adhering to said sterilized Therefore, when the object to be sterilized is put in a bag and autoclaved, water droplets attached to the object to be sterilized in the bag are removed, and after the autoclave is completed, the object to be sterilized is taken out of the autoclave device and used. In doing so, the operation of extracting water droplets from the object to be sterilized is eliminated.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a view for explaining an embodiment of the present invention. FIG.
(B) is an internal schematic structural diagram, in which 10 is an autoclave apparatus main body, 20 is a dry air supply can, and the air in the can 20 is dried by the heater 21 to low humidity, and the autoclave ends. Thereafter, the blower 22 is driven and the valves 23 and 24 are opened, and the dry air in the can 20 is supplied to the autoclave apparatus 10 through the pipe 25, and the high-pressure steam of the autoclave apparatus 10 is supplied to the dry air supply can 20 through the pipe 26. Although the inside of the autoclave apparatus 10 is dried, when the object 8 to be sterilized is contained in the bag 7, the inside of the bag is not sufficiently dried, and the object to be sterilized is removed from the autoclave apparatus 10. When removed from the container, water droplets may still adhere to the material to be sterilized.

According to the present invention, in order to solve the above-described problem, a heater 11 for heating water in the autoclave apparatus to generate high-temperature and high-pressure steam for the autoclave is installed in the autoclave apparatus 10 to provide a remote controller. Infrared heater 12
Provided, after the end of the autoclave, when supplying the dry air,
The infrared heater 12 is operated together with the supply of the dry air.

The far-infrared ray generally refers to an electromagnetic wave having a wavelength longer than about 5 μm, and far-infrared rays having a wavelength of 2.5 μm to 25 μm are widely used in industry. This far-infrared ray is absorbed by the inside of the object and exerts a heating effect. However, depending on the substance, the far-infrared ray is transmitted, for example, through a thin transparent bag or the like, and the object in the bag (sterilized Object) and heats the object.

Therefore, if the far-infrared heater 12 is provided in the autoclave apparatus 10 as in the present invention, even when the object 8 to be sterilized is placed in the bag 7 and autoclaved, the object in the bag 7 can be covered. Since the sterilized object 8 can be effectively heated by far infrared rays, water droplets adhering to the sterilized object 8 can be removed.

[0013]

As is apparent from the above description, in the present invention, the far-infrared heater is provided in the autoclave apparatus, and the far-infrared heater heats and dries the article to be sterilized put in the bag. Therefore, even if the object to be sterilized is placed in a bag, after the autoclave, when the object to be sterilized is removed from the autoclave device, water droplets and the like are not attached to the object to be sterilized. And can be used immediately, which not only saves labor but also improves work efficiency.
