[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sterilization apparatus, and more particularly, to a sterilization apparatus capable of rapidly sterilizing various surgical instruments and equipment used in dental treatment and the like.

[0002]

2. Description of the Related Art In dental treatment or various other surgical treatments, various treatment tools or equipments are used. To be used.

[0003] As a typical sterilizer, an autoclave (high-pressure steam sterilizer) is commercially available. Thus, in the conventional autoclave device, after the objects to be sterilized, for example, cones, tweezers, syringes, gauze, cotton wool, and the like are put into a tray and stored in a closed chamber having an opening / closing door, the door is locked. Then, the closed chamber is supplied with water and heated, and the heated steam (for example, 121 ° C. or 132 ° C.)
Sterilization (for example, for 20 minutes or 10 minutes), then, after evacuating the steam in the closed chamber, drying the closed chamber,
The object to be sterilized is dried, and then the door is opened to take out the object to be sterilized.

[0004]

In the above-mentioned conventional autoclave device, the time required for sterilization is, as a standard,
It takes about 10 to 20 minutes, but it takes about 10 minutes to heat water and about 20 minutes to dry, and spends more than half of the time required for sterilization in pre-treatment and post-treatment not directly related to sterilization. Was.

[0005] The present invention has been made in view of the above situation, and particularly, in an apparatus for performing steam sterilization,
It is an object of the present invention to provide a sterilization apparatus capable of performing a sterilization process only by a sterilization time for substantially eliminating the heating time and the drying time.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a heating tank for obtaining hot water of approximately 100 ° C., and a hot water connected to the heating tank and led from the heating tank. and steam tank for obtaining heat to pressurized steam, is detachably connected to the steam tank, Ri consists an open sterilization tank pressurized steam is supplied from the steam tank, the steam tank Multiple sterilization
The tank is connectable .

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is an overall configuration diagram for explaining one embodiment of the present invention, in which 1 is a heating tank, 2 is a steam tank, 3 is a sterilization tank, and the heating tank 1 is, for example, Like an electric pot, the water inside is always heated and kept at a temperature close to 100 ° C., and running costs are low.

Reference numeral 2 denotes a steam tank (steam generator). Hot water heated by the heating tank 1 is supplied to the steam tank 2 through a shut valve 3, and after the shut valve 3 is closed, the steam tank is closed. The hot water supplied to 2 is heated and becomes high-pressure steam (steam).

The steam tank is provided with a plurality of outlet passages, and each outlet passage is provided with a distribution valve 4, and a sterilization tank 5 is connected through each of the distribution valves. ing.

Each of the sterilization tanks 5 is configured to be small in size, and can be expanded to compensate for the capacity shortage accompanying the miniaturization. These sterilization tanks 5 can be used simultaneously or sequentially by operating the distribution valve 4. By operating the distribution valve 4, high-pressure steam from the steam tank 2 is supplied. This sterilization tank 5 has a door 5a.
The object to be sterilized is stored using the door 5a,
After the storage, the door 5a is closed, and the distribution valve 4 is operated as described above, so that the steam tank 2 is placed in the sterilization tank 5.
Supply higher pressure steam, and after a predetermined time elapses (for example,
(After 10 to 20 minutes) Open the door 5a and take out the object to be sterilized.

In each sterilization tank 5, as described above,
High-pressure steam is supplied from the steam tank 2 to sterilize the object to be sterilized in the sterilization tank 5. At this time, steam may be continuously supplied from the steam tank 2. After the high-pressure steam is supplied from the steam tank 2 for a predetermined time, the distribution valve 4 may be closed, and then the heater provided in each sterilization tank 5 may be used to keep the temperature. Thus, even if a heater is built in each sterilization tank,
Since the heater is for maintaining the temperature, the capacity is small, and the cooling after the heater is shut off is quick. In addition, 5
b denotes a pressure regulating valve provided in each sterilization tank 5, which is automatically adjusted so that the pressure in the sterilization tank does not exceed a predetermined pressure.

Although the outline of the present invention has been described above, each component in the present invention, for example, a heating tank,
Steam tanks, sterilization tanks, etc. may be individually and separately arranged, and these may be connected through a pipe,
Practically, these are configured as a single unit close to each other, and the unit is made portable by casters or the like, so that the usability is improved and the space can be effectively used.

[0013]

As is clear from the above description, according to the present invention, water is heated to just before boiling in a heating tank, and the heated water is guided to a steam tank to obtain pressurized steam. Since the water is preheated to a temperature close to 100 ° C., the time required to obtain steam at a specified pressure is extremely short, and the ratio of the sterilization time to the total processing time can be reduced.

Since the heating section (heating tank, steam tank) and the sterilization section (sterilization tank) are separated, the burden on the sterilization section is reduced, and it is possible to install a plurality of sterilization tanks. This makes it easy to increase the number of sterilization tanks according to the increase in the amount of treatment work, and suppresses the increase in the number of treatment tools and equipment. In other words, according to the conventional autoclave, the sterilization process takes a long time,
A large number of equipments had to be prepared and sterilized beforehand, and the purchase of therapeutic instruments and equipment required a great deal of expense.

In order to reduce the number of therapeutic instruments and equipment, it is necessary to provide a plurality of autoclave devices, which requires additional costs and requires additional space, but according to the present invention, Since only the sterilization tank needs to be added, the cost can be reduced, and the space for it can be reduced.

Further, in the present invention, since drying after the sterilization is eliminated, not only the total sterilization time can be remarkably shortened, but also the sterilization tank can be reduced in size and cost. In addition, the cooling of the sterilization tank and the object to be sterilized after the sterilization process is quick, and the working efficiency is good.
