Description

[Detailed Description of the Invention] "Industrial Application Field" The present invention is suitable for use in existing relatively small spaces such as hospital operating rooms, etc., where a large number of surgical tools and the like must be housed in a cluttered manner. This invention relates to a rational steam sterilizer that can be installed without requiring as much space as possible for opening and closing the door, and without any complications such as the need to modify the building in which it is installed.

``Prior art'' Conventionally, this type of steam sterilization and disinfection device was usually hexahedral in shape and had a door on the front that opened and closed in an axial manner, making it difficult to install it in a small operating room, etc. In this case, a large amount of half-plane space is required for the axial movement of the door, which limits the space for placing other tools, which is a great inconvenience. Disinfectors that store high-pressure steam throughout the process have disadvantages such as damage to the welded parts, resulting in steam leakage and frequent repairs.
In addition, in order to eliminate the need for horizontal axial movement space on the front surface for opening and closing the door, a similar hexahedral container has a cover that can be slid up and down, instead of opening and closing the door axially. However, it is difficult to seal it tightly, and since the cover opens upwards, it requires a lot of space upwards, and when large objects are installed, it may hit the ceiling when opening and closing in existing rooms. The installation was difficult, and the installation required major construction work such as rebuilding the ceiling, which caused considerable difficulties.

``Problems to be solved by the invention'' The dead space for opening and closing the cover is made as small as possible, and there is a large space for storing other items, without the need to modify existing buildings for installation. It is an object of the present invention to provide a steam sterilizer that can be installed in multiple locations and that does not cause gaps between welded parts even when high-pressure steam or the like is stored continuously.

"Means for Solving the Problem" In the present invention, the overall shape is not hexahedral but approximately cylindrical, and the cover is slidable in an arc along the cylindrical surface to open and close the front and back. In addition to eliminating the need for special vertical dead space, by changing the overall shape, there are almost no welded parts, so even if high-pressure steam is accommodated, problems such as leakage will not occur. It is something to do.

"Embodiments and Effects" The attached drawings show an example of carrying out the present invention, in which 1 is a main body which is entirely cylindrical, both ends 2 and 2 have approximately bowl-shaped curved surfaces, and the intersecting parts of the surfaces are cylindrical. This is the type of explosive contact that occurs in the direction of the extension line of both ends. Reference numeral 4 designates an entrance and exit hole bored in the center of the cylindrical side surface. Reference numeral 5 denotes an arc-shaped frame body that is connected to cover the outer peripheral portion 6 of the entrance/exit. Reference numeral 7 denotes an arc-shaped cover, and sliding grooves 10 and 11 are formed in the upper end 8 and both side ends 9 of the arc-shaped frame.
．． 12 and the through groove 13 provided on the lower side.
4 and is slidably fitted therein. Reference numeral 15 denotes a frame, which stably supports the main body 1 at an arbitrary height;
If desired, it can be equipped to be movable on the floor in any direction using a vehicle 16. Reference numeral 17 denotes a hydraulic cylinder, which is mounted between the frames 15 in an obliquely recumbent manner, and the piston 18 is used to open and close the lid by sliding it up and down.
The tip is pivoted to the cover 7.

The present invention has the above structure, and when opening and closing the cover,
It does not require a space in front of the main body to pivot like a door, and also does not require special space to move up and down in the vertical direction, and can be opened and closed by sliding slightly in an arc along one side of the outer periphery of the main body. Therefore, it does not require dead space for opening and closing the cover when installed in a narrow operating room, etc., and the main body is not a hexahedron with perpendicular surfaces that are in explosive contact with each other, but is cylindrical and the side ends are in the extending direction. Since it is in explosive contact with the weld, there is no risk of problems such as leakage of high-pressure steam from the welding gap even though it accommodates high-pressure gas.

"Effects of the Invention" In the present invention, when opening and closing the entrance/exit, the cover 7 slides open and close along the arc-shaped side surface of the cylindrical main body 1. There is no need to equip a space for opening and closing, and it can be used in a small operating room (it can be used in a small operating room, etc.), and it can be installed in a small operating room, etc. without changing the structure of the operating room, etc. during installation. The effect is remarkable.
