Abstract

The present invention relates to a method and system for aseptically filling of flexible packages containing dry cloth. Such a method may include a first stage that is performed in a non-sterile environment. The first stage may include cutting a first substantially dry cloth to a predetermined size; inserting the first cloth into a flexible package; sealing a first end of the flexible package; and sterilizing the flexible package. The method may also include a second stage performed in a sterile environment. The second stage may include filling the flexible package with a medical solution such that the substantially dry cloth absorbs at least a portion of the medical solution; and sealing the an open end of the flexible package.

First claim

What is claimed:

1. A method, comprising:
a first stage of the method performed in a first environment, the first environment being non-sterile, the first stage comprising the steps of:
first cutting a substantially dry cloth to a predetermined size;
second inserting the substantially dry cloth into a substantially tubular flexible package;
third sealing a first end of the flexible package; and
fourth sterilizing the flexible package by irradiating the flexible package;

a second stage of the method performed in a second environment, the second environment being sterile, the second stage comprising the steps of:
first filling the flexible package with a medical solution such that the substantially dry cloth absorbs at least a portion of the medical solution; and
second sealing a second end of the flexible package.

2. The method of claim 1 , wherein sterilizing the flexible package includes exposing the flexible package to between 25 kGy and 50 kGy.

3. The method of claim 1 , the first stage further comprising sealing the second end of the flexible package after sealing the first end of the package and the second stage further comprising opening the second end of the flexible package prior to filling the flexible package.

4. The method of claim 3 , wherein opening the second end of the flexible package comprises cutting a sealed portion from the second end of the flexible package.

5. The method of claim 1 , wherein the first stage further comprises at least partially enclosing the flexible package in a wrap.

6. The method of claim 5 , wherein the flexible package is fully enclosed in the wrap.

7. The method of claim 6 , wherein the wrap comprises a polyethylene bag.

8. The method of claim 1 , wherein filling the flexible package with the medical solution includes aseptically filling the flexible package with the medical solution.

9. The method of claim 1 , wherein the medical solution includes chlorhexidine gluconate.

10. The method of claim 1 , wherein the medical solution includes about 2% chlorhexidine gluconate.
