Abstract
The present invention provides a microorganism inspection system that is capable of instantly inspecting individual containers for microorganism contamination of the containers that are filled with or accommodate medicines and the like. The present invention has a supply means for supplying a predetermined amount of clean air to the inside or the outer surface of a container, a collecting means for collecting the air supplied to the container by the supply means, and a detecting means for detecting microorganisms included in the air collected by the collecting means.
Claims9
A microorganism contamination inspection system for inspecting microorganism contamination of an inside or on a surface of a container, comprising:
- (a) supply means for supplying a first predetermined amount of clean air to the inside or the surface of the container, the supply means including:
- an air-compressor configured to deliver compressed air to an outlet of the compressor;
- a sterile filter disposed at the outlet of the compressor to receive the compressed air and to transmit clean compressed air directly to a clean air supply line;
- the clean air supply line located to accept the clean compressed air from the sterile filter and to deliver the clean compressed air directly to an ejection nozzle terminating said clean air supply line and through the ejection nozzle directly to the container;
- and
- the ejection nozzle having a nozzle outlet that, in operation of the system, is either inserted into a mouth of the container or disposed at a location at the surface of the container;
- (b) collecting means for collecting a second predetermined amount of air from the container, the collecting means including:
- a collector unit dimensioned as a shell having an internal volume and an opening, the opening providing fluid access to the internal volume,
- wherein, in operation of the system, the opening is positioned to cover either said mouth of the container or said location at the surface of the container, and
- wherein the ejection nozzle passes through the shell and through the opening;
- a main suction pipeline having a first end and a second end, wherein the first end is directly connected to the internal volume, wherein the second end is directly connected to a first suction pump;
- and
- the first suction pump separated from the shell and the internal volume of the collector unit by the main inspection supply line and configured to generate suction to intake the second predetermined amount of air from the container and through the volume into the main suction pipeline;
- and
- (c) detecting means for detecting a microorganism contained in the second predetermined amount of air,
- wherein said detecting means is disposed at the main suction pipeline between the first and second ends to separate the first pump from the collector unit and to receive a portion of the second predetermined amount of air from the container through the internal volume of the collector unit into the main suction pipeline during an operation of the first pump.
