BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an autoclave for sterilizing medical instruments and the like.

[0002]

2. Description of the Related Art In a conventional autoclave in which a sterilized product such as a medical instrument is sterilized by steam, a cylindrical can is fixed, and a lid provided at an end of the can is opened to open the can. The sterilized product is taken in and out of the interior.

[0003]

The conventional autoclave is of a horizontal type which horizontally supports a can body, and therefore has a disadvantage that it is difficult to take in and out a sterilized product.

The technical object of the present invention is to solve the above-mentioned inconveniences and to make it easier to put in and take out a sterilized product.

[0005]

In order to solve the above-mentioned problems, in the present invention, a fixed support plate having a steam inlet and a cylindrical shape having a lower part opening detachably mounted on the support plate are provided. And a steam generator for supplying steam to the can body from the steam inlet of the support board, and a tray receiving tray for supporting a sterilized product is provided on the support board inside the can body. The configuration was adopted.

[0006]

In the autoclave having the above construction, the sterilized product supported by the tray on the receiving table is covered with a can placed on the support board, and the steam introduced from the steam inlet into the can body. Sterilize the sterilized product.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, the support plate 1 has an annular bulge 2 on the upper surface, and a steam inlet 3 is provided inside the bulge 2.

A cylindrical can body 4 having a lower end opening is detachably mounted on the bulging portion 2, and the can body 4 is formed of an outer cylinder 4a and an inner cylinder 4b and has heat insulation. I have.

A seal groove 5 is formed on the inner periphery of the bulging portion 2, and a seal member 6 is attached to the seal groove 5.

Here, the sealing member 6 is formed of an annular substrate portion 6.
a has a U-shaped cross-sectional shape in which a seal lip 6b is formed inward from the outer periphery of the inner cylinder 4b.
Is elastically in contact with an arcuate surface 4c formed at the lower portion of the inner periphery of the can 4 so that when the pressure inside the can 4 increases, the sealing lip 6
b strongly adheres to the inner cylinder 4b.

The can 4 is held in a state of being placed on the bulging portion 2 by the operation of the lock mechanism 10.

As shown in FIGS. 2 and 3, the lock mechanism 10 is provided on the support board 1 and concentrically with the can body 4.
A plurality of insertion holes 12 penetrating through the support cylinder 11 in the radial direction are formed at predetermined intervals in the circumferential direction, and a halfway of the engagement piece 13 inserted through each of the insertion holes 12 is formed in the support cylinder 11. It is swingably supported by a pin 14, and the outer end of an engagement piece 13 located outside from each insertion hole 12 is swingably connected to an annular plate 15 provided outside the support cylinder 11 by a pin 16, By operating the handle 17 provided on the annular plate 15, the annular plate 15 is rotated about the support cylinder 11, and the engagement piece 1 is
3 is swung so that the inner end of the engaging piece 13 is disengaged from an engaging groove 18 provided on the lower part of the outer periphery of the can 4.

A cylindrical body 20 is provided on the upper surface of the support plate 1 coaxially with the steam inlet 3. A tray 21 for supporting a sterilized product is provided on a stepped portion 21 formed on the upper inner periphery of the cylindrical body 20. The cradle 23 is supported.

Here, a plurality of holes 24 are formed in the tray 22 so that steam can flow therethrough. The tray 22 may be fixed on the receiving base 23 or may be detachably mounted on the receiving base 23. When the tray 22 is detachably supported, a suspension shaft 26 having a ring 25 is provided on the tray 22.

On the other hand, the pedestal 23 is made of punched metal so that steam can flow therethrough.

A steam generator 30 for supplying steam from the steam inlet 3 to the inside of the can 4 is provided below the support plate 1.

The steam generator 30 has a water storage tank 31 mounted on the lower surface of the support plate 1 and an annular groove 32 formed in the outer peripheral portion of the bottom plate of the water storage tank 31, and is turned on and off by the operation of a thermistor 34 in the annular groove 32. A heater 33 is provided, and the heat generated by the heater 33 heats water contained in the annular groove 32 to generate steam.

The water supply to the annular groove 32 may be manually performed, or a water supply pipe having an outlet facing the annular groove may be provided, and an electromagnetic valve provided in the middle of the water supply pipe may be controlled to automatically supply water. Is also good.

The autoclave shown in the embodiment has the above-mentioned structure.
After the sterilized product A is supported by the tray 22 placed thereon, the can 4 is placed on the bulging portion 2 to cover the sterilized product, and after the can 4 is fixed by the operation of the lock mechanism 10, Heater 33
Is heated, and water stored in the annular groove 32 is heated to form steam, and the steam is filled in the can 4 to sterilize the sterilized product.

After the sterilization process, the steam inside the can 4 is leaked to the outside from an exhaust steam pipe (not shown), and the lock mechanism 10
Is released, the can body 4 is pulled up and removed from the support board 1. By removing the can 4, the tray 22 supporting the sterilized product appears outside, so that the sterilized product can be easily taken out.

In the embodiment, the steam generator 30 is connected to the lower surface of the support board 1, but the steam inlet 3 of the support board 1 and the steam generator 30 are connected by a steam inlet pipe. Is also good.

[0023]

As described above, in the autoclave according to the present invention, a tray receiving tray for supporting a sterilized product is provided on a supporting plate having a vapor inlet, and a can body covering the receiving plate is placed on the supporting plate. Because the tray on the cradle appears outside by removing the can,
It is very easy to put in and take out the sterilized product.

Further, as in the autoclave according to the second aspect, a groove is formed in the bottom plate of the water tank, and a heater is provided in the groove to heat the water in the groove, so that the flat water in the water tank is formed. As compared with a case where a predetermined amount of water is stored and heated by a heater, the heating efficiency of the stored water is better, and steam can be effectively formed.
