Sterilizing container and endoscopic system
A sterilizing container houses an endoscope having openings and an inner region communicating with the openings at a time of an autoclave sterilization. In the sterilizing container, a gap portion of a predetermined volume is formed at a position to which the opening faces when the endoscope is housed in the sterilizing container, and a steam entrance path, which communicates the gap portion with an outside space of the sterilizing container, is formed so as to guide steam fed from the outside space at the sterilization to the inner region of the endoscope via the gap portion and the openings.
1. An endoscopic system comprising:
an endoscope having openings to communicate with an inner region of the endoscope;
a sterilizing container that is adapted to house the endoscope and that has a plurality of pits on at least a side surface of the sterilizing container, and ventilation holes for communicating with an outside space of the sterilizing container, said ventilation holes being formed respectively in the pits; and
a sterilizing package which is formed from a steam-permeable filter and an optically-transparent film in at least one portion of an outer periphery of the sterilizing package, and is adapted to house the sterilizing container inside at the time of autoclave sterilization such that the optically-transparent film faces to the ventilation holes, wherein
in the sterilizing container,
a plurality of gap portions of predetermined volumes are formed at positions to which the openings face when the endoscope is housed in the sterilizing container, and
a steam entrance path, which communicates the gap portions with an outside space of the sterilizing container, is formed so as to guide steam fed from the outside space at the sterilization to the inner region of the endoscope via the gap portions and the openings; and
a cross-sections area of each of the gap portions and the steam entrance path in a plane perpendicular to an entering direction of the steam is equal to or larger than a cross-sections area of each of the openings.
2. The endoscopic system according to claim 1 , wherein
the openings comprise:
channel openings, each of which communicates with a predetermined channel formed inside the endoscope; and
a ventilating opening that serves to communicate an external surface of the channel with the outside space of the endoscope, and
the gap portions are formed corresponding to the channel openings and the ventilating opening.
3. The endoscopic system according to claim 2 , wherein the ventilating opening is formed on an electrical connector which electrically connects internal electric circuitry with an external device.
4. The endoscopic system according to claim 2 , wherein
the endoscope includes an insertion to be inserted into an object at a time of use, and an operating unit located outside the object and used for a manipulation by a user of the endoscope, and
the ventilating opening is formed on a partial region of the operating unit.
5. The endoscopic system according to claim 2 wherein
the endoscope includes an insertion to be inserted into an object at a time of use, and an operating unit located outside the object and used for a manipulation by a user of the endoscope, and
the channel openings are formed on a tip end of the insertion and a partial region of the operating unit.
6. The endoscopic system according to claim 1 , further comprising
an autoclave sterilizing apparatus including
a chamber that houses the sterilizing package at the time of the autoclave sterilization so that the optically-transparent film is located at a vertically upward side and the steam-permeable filter is located at a vertically downward side, and
a ventilating unit that secures a ventilating state between the steam-permeable filter forming the sterilizing package and an inside space of the chamber, and that is located below the sterilizing package so that the ventilating unit is in contact with the vertically downward side of the sterilizing package at the time of the autoclave sterilization in the chamber, wherein
the sterilizing container includes a visual confirmation unit that allows visual confirmation of the endoscope housed in the sterilizing container and that is provided at the vertically upward side, and
the sterilizing container is housed in the sterilizing package so that the endoscope can be visually confirmed from outside at the time of the autoclave sterilization via the visual confirmation unit and the optically-transparent film arranged on the vertically upward side of the sterilizing package.
7. The endoscopic system according to claim 6 , wherein
the ventilating unit includes
a net member that is arranged in contact with a lower surface of the sterilizing package, and
a leg that secures a gap between the net member and a bottom portion of the chamber.
8. The endoscopic system according to claim 6 , wherein
the visual confirmation unit is formed by providing a predetermined opening or by providing a transparent member on the predetermined opening.
9. The endoscopic system according to claim 6 , wherein
the endoscope includes a chemical indicator that displays a sterilization effect by the autoclave sterilization at a position which can be visually recognized from outside via the visual confirmation unit when the endoscope is housed in the sterilizing container.
