Problems solved by technology

[0008] However, each time the downstream test section access door 116 is opened to test the strainer 106, the potential exposure to biohazards within the housing 102 increases.
In addition, it is very expensive to install a new integrated automatic scanning mechanism
Furthermore, upgrading a manual bag with gloves to permanently automatically integrate the scanning probe 108 within the housing 102 may require replacing the entire barrier system 100

Embodiment Construction

[0020] figure 2 For one embodiment of the barrier system 200 there is a housing 280 containing the downstream test section access door assembly 240 . A conventional barrier system, such as the aforementioned barrier system 100 , can be retrofitted into the barrier system 200 by replacing the downstream test section access door 116 with the downstream test section access door assembly 240 . Its advantages are described below.

[0021] Housing 280 includes upstream section 216 , screen section 218 , and downstream testing section 220 . Upstream section 216 is separated from downstream testing section 220 by screen section 218 . Upstream section 216 is connected to upstream vent tube 202 . The upstream vent duct 202 may include an air inlet duct 204 , a transition zone 206 , a regulator valve 20 , and a vent duct 210 that may selectively communicate between the regulator valve 208 and the transition zone 206 . Downstream testing section 220 is connected to downstream ventilat...

Abstract

An access door that includes a scanning mechanism for a containment system, a containment system having the same, and a method for leak testing a filter installed in the containment system are described herein. In one embodiment, a containment system is disclosed that includes a housing having a downstream test section access port selectively sealed by a downstream test section access door. A displacement assembly is coupled to the downstream test section access door and is operable to move a plurality of probes disposed in the housing relative to the test section access door.

Description

technical field [0001] The invention relates to an access door, comprising a scanning mechanism for a barrier system, a barrier system with the scan mechanism, and a method for leak testing a filter installed in the barrier system. Background technique [0002] Barrier systems are relied upon by laboratories testing highly toxic and deadly chemicals, pharmaceuticals, viruses, and organics. Each potential leak point represents a source of a potentially catastrophic biohazard that could release and expose technicians and / or the surrounding environment. [0003] FIG. 1 shows a conventional barrier system 100 having an inlet 124 and an outlet 126 . The conventional barrier system shown generally comprises a series of multiple elements arranged in a housing 102 . Components in housing 102 generally include screen 106 , scanning mechanism 108 , upstream section 110 and downstream testing section 112 . Barrier system 100 also includes downstream test section access door 116 and ...
