Description

[Detailed Description of the Invention] The present invention relates to a steam sterilizer for sterilizing medical instruments, and more particularly to an improved structure of a storage tray on which objects to be sterilized are placed.

In the case of this type of steam-type sterilizer, high-temperature, high-pressure steam is ejected and filled into the chamber that stores the objects to be sterilized, and the stored objects are placed on a shelf placed in advance at the bottom of the chamber. This is done by leaving the site in place. In this case, the ejected high-temperature, high-pressure steam is ejected directly toward the placed objects to be sterilized, wetting the objects to be sterilized, resulting in a reduction in sterilization efficiency. In addition, when storing or removing objects to be sterilized, it is necessary to reach deep into the heated chamber, and there is a risk of getting burned if your hand or arm comes into contact with the opening of the heated chamber during such operations. There were flaws.

The present invention has been developed in consideration of these points, and one embodiment of the invention will be described below with reference to the drawings. Reference numeral 1 denotes the sterilizer body, which has a cylindrical chamber 3 disposed within an outer box 2, and high-temperature, high-pressure steam is ejected into the chamber.

The front opening 4 of the chamber 3 has an opening/closing lid 5.
can be airtightly closed via a gasket 6, and a steam pipe 8 is formed protruding from approximately the center of the back wall 7 to eject high-temperature, high-pressure steam led from a steam generator (not shown). The steam outlet 9 opens toward the inner bottom 10 of the chamber, and the ejected steam is ejected along the back wall 7, goes around from the inner bottom 10 to the circumferential side, and reaches the entire area inside the chamber 3.

A notch 11 with a downward opening is formed at the tip of the steam pipe 8 at a position forward of the steam outlet 9, and a mounting shelf, which will be described later, can be locked in the notch.

Reference numeral 12 denotes a mounting shelf detachably disposed inside the chamber 3, which has a substantially L-shaped side surface, is laid with a gap S between it and the inner bottom 10 of the chamber 3, and has both side edges of itself. 13, 13 are placed on the inner wall surface 14 of the chamber 3, and the upper edge 16 of the vertical wall 15 formed at the back of the chamber 3 is connected to the steam pipe 8.
It can be removably locked in a notch 11 formed in the. The horizontal center portion of the mounting shelf 12 is hollowed out to form a picture frame shape with a window hole 17. The mounting shelf 12 having such a configuration is shown in FIG.
As shown by the two-dot chain line in FIG.
The upper edge 16 of the steam pipe 8 can be released from the steam pipe 8, and can be attached and detached very easily.

Reference numeral 18 denotes a storage tray that is superimposed on the upper surface of the shelf 12, on which objects to be sterilized can be placed. This can be easily done by pulling out only 18 towards you.

As mentioned above, the steam sterilizer of the present invention has a cylindrical chamber with an opening/closing lid at the front opening and a steam pipe with a steam outlet protruding from the rear wall at the rear. A shelf for placing objects to be sterilized, which is placed with a gap from the inner bottom of the chamber, is placed with both side edges on the inner wall surface of the chamber, and the upper edge of the vertical wall at the back thereof is placed on the inner wall of the chamber. Since it is removably locked to the notch at the tip and the storage tray can be pulled out and placed on the shelf, the ejected steam is not blown directly onto the objects to be sterilized, which is different from conventional methods. Since the sterilization efficiency does not decrease as shown in FIG. .
