Abstract

A system for sterilizing an object including a hollow cassette for containing the object, a sealable opening in the cassette for ingress and egress of the object, a seal for forming a fluid-tight seal around the opening, input and output ports in the cassette for receiving and exhausting a sterilizing fluid and a sealing check valve in the input and output ports for providing a fluid-tight seal when no connections are made to the input and output ports such that when the object is sterilized within the cassette, the cassette will maintain a sterilized atmosphere for the object until the cassette is opened to allow use of the object.

Claims7

Dependent claims

A device utilizing a sterilizing agent to sterilize a lumened object, said lumened object having a part having a neck portion and an outer flange at the top of said neck portion, said device comprising:

a cassette for containing said lumened object, said cassette comprising;
a first container section;
a second container section engaged with said first container section;
a fluid-tight inner cavity formed between said first container section and said second container section;
and
an input port in the casseette for receiving a sterilizing agent into said inner cavity;
an output port, separate from said input port, said output port connectable to a vacuum source and including a passage through which the sterilizing agent is expelled from said inner cavity;
and
a connector having a first connecting portion connectable to said lumened object and a second connecting portion connectable to said output port;
said first connecting portion comprising a seal for creating a fluid-tight connection about said neck portion of said port of said lumened object;
whereby said lumened object is connected to said connector and said connector is connected to said outport port and the first container section is engaged with the second container section to form said fluid-tight inner cavity in which the lumened object is retained;
sterilizing agent is introduced through said input port into said inner cavity where it sterilizes the outside surface of the endoscope and a vacuum is applied to the output port and the sterilizing agent is expelled from the inner cavity by passing through a lumen of the lumened object, thereby sterilizing the lumen, and passing through the passage and out of said cassette.

9 more elements

A method for sterilizing and storing endoscopes comprising the steps of:

a) providing one or more endoscopes, each of said endoscopes including an outer surface and at least one lumen;
b) providing a sealable cassette comprising:
i) a first container section;
ii) a second container section engagable with said first container section;
iii) an input port;
and
iv) an output port;
and
c) providing a connector for connecting the one or more endoscopes to said output port;
d) connecting an end of each of the endoscope(s) to said connector;
e) connecting said connector to said output port;
f) engaging said first container section with said second container section to create a fluid-tight inner cavity therebetween, said one or more endoscopes being enclosed within said fluid-tight inner cavity;
g) introducing a gaseous sterilizing agent into said inner cavity through said input port to sterilize the outer surface of said one or more endoscopes;
h) applying a vacuum to said output port and expelling the gaseous sterilizing agent within said inner cavity by drawing the gaseous sterilizing agent through the endoscope(s) lumen(s) at subatmospheric pressure and through said connector and through said output port and out of said inner cavity.
