Abstract
Modulevide.TM. 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 .TM. ) . Upon failure of vacuum in the branch piping, the ModuleVide .TM. activates to reestablish vacuum service in that branch piping segment. The branch of piping may for example correspond to the surgical theater suite of a hospital. The vacuum capacity of the ModuleVide .TM. is sized to match the specific Critical Zone branch's expected demand.
Description
CRITICAL CARE BACKUP VACUUM SYSTEM AND METHOD OF USE
Cross Reference to Related Applications This application claims the benefit of priority under 35 U.S.C. 119 (a) and (b) to U.S. Provisional Patent Application No. 62/291,074 filed February 4, 2016, the entire contents of which are incorporated herein by reference.
Background Centrally piped medical vacuum (suction) is an essential service within acute care hospitals. It is fundamental to patient care protocols in emergency, intensive care, operative, post operative, and general care departments.
Without adequate centrally piped suction service, hospitals cannot maintain critical care patient therapies and in certain cases must evacuate critical patients to other facilities.
In many medical facilities such as hospitals, there is often a central vacuum production plant or equipment that is connected to outlets throughout the facility via a piping network. Failure of this central vacuum system leads to loss of medical vacuum throughout the facility. Although the central medical vacuum plants are generally designed to provide redundancy through multiple pumps, these systems remain vulnerable to single faults such as loss of electrical power, inadvertent isolation valve closure, or pipeline breach.
Due to the critical nature of medical vacuum in patient care, many different options have been developed to manage central vacuum system failures. The most common solution is to deploy portable vacuum systems for direct use on patients, or to attempt to reestablish vacuum in the main piping system. This approach has several problems. The number of portable units required is generally large and cost prohibitive, leading to a shortage of pumps and a "rationing" of vacuum service. The portable units must be deployed, which takes considerable time. Combined with a vacuum service rationing protocol, this time lag to access can be long enough to compromise patient care. The situation can be further exacerbated by the fact that the portable vacuum pumps are not in regular service. Thus, some portables fail due to their long dormancy.
Numerous technologies are proposed to speed facets of portable vacuum deployment (for example CA2635506 C) or the return of central vacuum service (for example US6131596 A). These auxiliary technologies can only achieve a measure of improvement in the time to vacuum service restoration.
Because of the critical medical necessity for patient care, there have been a number of alternative backup vacuum technologies and strategies proposed in the literature. These solutions address a variety of specific central vacuum loss circumstances.
EP2058520 B1 titled "Backup vacuum-production installation and corresponding vacuum-production system" proposes a combination pneumatic vacuum motor and venturi that uses compressed air to produce suction. "As noted, if vacuum supply loss, for example during a power failure, the response time should be very short so as not to endanger the lives of patients in need of care requiring vacuum." The EP2058520 B1 system is capable of providing vacuum in case of a complete power failure, such as loss of main power and backup generator power. This solution addresses the critical time to vacuum recovery issue for an entire facility by providing a short term pneumatic powered vacuum system for a limited period of time.
In any medical facility, there are known areas and functions where vacuum service is expected to be of critical concern on a routine basis ("Critical Zones").
These Critical Zones will often include a surgical theater or suite of adjoining surgical theaters in a surgery center. Intensive care units and emergency rooms are other large facility segments where vacuum service is expected to be of critical concern. Loss of vacuum for even a few minutes in these types of areas may endanger patient lives.

Summary The ModuleVideTM Solution ModuleVideTM 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 (ModuleVideTm). Upon failure of
2 vacuum in the branch piping, the ModuleVideTM activates to reestablish vacuum service in that branch piping segment. The branch of piping may for example correspond to the surgical theater suite of a hospital. The vacuum capacity of the ModuleVideTM is sized to match the specific Critical Zone branch's expected demand. When portable vacuum generators are used to try to create vacuum in the medical piping system, the portable vacuums are generally attached via gauge ports. These gauge ports are normally 1/8 inch diameter, regardless of pipeline diameter, which is generally 3/4" up to as large as 2" for Critical Zones.
This introduces a severe flow restriction between the portable vacuum generator and the piping, further limiting the effectiveness of the portable vacuum units.
Because ModuleVideTM is an integrated solution, the connections between ModuleVideTM
vacuum system and the Critical Zones piping branch can be appropriately sized and designed to prevent flow restrictions. Hence, with the ModuleVideTM, the various limitations of portable vacuum generators are avoided entirely.
The ModuleVide TM design further addresses the situation of piping structural failures outside the Critical Zone branch causing a loss of vacuum in the Critical Zone priority branch. A key element of the ModuleVideTM design is the use of isolation valves to render the ModuleVide TM piping branch fully autonomous from the failed main vacuum system. As a consequence, loss of piping integrity elsewhere in the main piping and lower priority piping branches (where the deployment of portable vacuums is expected to be an adequate solution) has no effect. This represents a particular benefit over having a redundant standard backup vacuum generator for the whole piping network. While the focus of ModuleVideTM is on Critical Zones, it is possible to apply the ModuleVideTM
device to less critical medical piping branches or segments if desired.
In accordance with an aspect of the present invention, there is provided a medical vacuum apparatus for supplying medical vacuum to a portion of a medical vacuum piping network (P) in a medical facility, the apparatus comprising:
a) a vacuum generating device (A) capable of causing a negative pressure within piping in fluid communication therewith (P), b) wherein the vacuum generating device (A) is fluidly connected to the portion of the medical vacuum piping network (P) in the medical facility,

8 ModuleVideTM Example System 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 ModuleVideTM 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 TM pipeline interconnect are two check valves (Cl, C2) serving to isolate the ModuleVideTM (A) emergency vacuum service to the Critical Zone. C2 prevents the ModuleVide TM pump from attempting to draw down vacuum across the central pipeline and thus the entire vacuum piping network.
When not in use, the Cl prevents the central vacuum system from drawing air through the idle ModuleVideTM vacuum pump. In a preferred arrangement, Cl and C2 are both installed in a vertical orientation.
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 TM . 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 TM to supplement an insufficient level of vacuum in the entire piping network to thereby reestablish sufficient vacuum service in the entire facility.
