CRITICAL CARE BACKUP VACUUM SYSTEM AND METHOD OF USE

Abstract

ModuleVide™ takes a unique approach to sustaining vacuum service in Critical Zones within a hospital or other medical facility. This solution relates to a medical facility with a main vacuum plant connected via a main piping with branches that deliver vacuum to different areas within the facility. Critical Zone branches off the central vacuum piping system are augmented with integrated branch backup vacuum generating devices (ModuleVide™). Upon failure of vacuum in the branch piping, the ModuleVide™ activates to reestablish vacuum service in that branch piping segment. The branch of piping may for example correspond to the surgical theater suit of a hospital. The vacuum capacity of the ModuleVide™ is sized to match the specific Critical Zone branch's expected demand.

DESCRIPTION OF PREFERRED EMBODIMENTS

ModuleVide™ Example System

[0035] A wall mounted DC current direct drive suction pump (A) interconnected to the zone piping via a full bore pipe “T” situated downstream of the zone isolation valve (E). The ModuleVide™ may (for example) be connected via low voltage wiring to the dry contacts within the local (zone) alarm (D) monitoring, and activates when the local alarm detects a loss of pressure in the central pipeline. Integral to the ModuleVide™ pipeline interconnect are two check valves (C1, C2) serving to isolate the ModuleVide™ (A) emergency vacuum service to the Critical Zone. C2 prevents the ModuleVide™ pump from attempting to draw down vacuum across the central pipeline and thus the entire vacuum piping network. When not in use, the C1 prevents the central vacuum system from drawing air through the idle ModuleVide™ vacuum pump. In a preferred arrangement, C1 and C2 are both installed in a vertical orientation.

[0036] The check valves may in some instances be replaced with actuated valves (AV1, AV2) for additional control over the system via a PLC. This provides further flexibility in the uses of ModuleVide™ . For example, a variety of issues can cause the vacuum level in a piping network to be sustained, but insufficient. An AV2 for example could allow for use of the ModuleVide™ to supplement an insufficient level of vacuum in the entire piping network to thereby reestablish sufficient vacuum service in the entire facility.
