Definitions
- the invention relates to systems for monitoring the status of conditions or alarm points or alarm variables in healthcare facilities or institutions and, more particularly, to a monitoring system for use in such facilities or institutions and using monitoring panels of modular character capable of monitoring a plurality of parameters and providing alarms or other communications signifying out-of-limit conditions.
- gas distribution in a hospital is monitored by medical gas alarms.
- the requirements for such alarms have been defined by the National Fire Prevention Association -(NFPA) .
- NFPA National Fire Prevention Association
- These medical gas alarms are typified by the use of separate alarm modules intended to measure separate lines or sources of gas pressure. That is, each separate module is dedicated to measuring a single gas for a particular parameter, such as pressure, which then displays the output of the pressure transducer in communication with the single gas and is programmed to sound an alarm if the pressure output exceeds or drops below a predetermined threshold.
- many operating rooms require an additional alarm system dedicated for that particular operating room so a physician or healthcare professional can make sure all systems are functioning properly.
- each panel in the presently- disclosed system is capable of monitoring the status of a plurality of piped medical gases or other conditions, such as pressure or temperature and giving indication in response thereto.
- the present system may for convenience be referred to in this description as a monitoring system in that parameters, variables, functions and values or conditions are monitored and may as monitored be used in typical operation of the monitoring system to provide an aural, visual or other alarm, or to result in a communication of a desired type even if not necessarily an alarm in the strict sense.
- variable means individual attributes (such as temperature, pressure, volume, value, status or other function) to be monitored during operation of the. system.
- out-of-limit condition is used in its broadest sense noted hereinabove, and means in general a situation or change of condition wherein such a parameter, variable, condition, function, status, condition or value or any equivalents or attribute thereof varies from predetermined limit or limits, as illustrated by overpressure or underpressure, overtemperature or undertemperature, status change, switch closing or switch opening or other change of status, or unacceptable or undesired or notable change which is desired to be sensed and monitored.
- alarm is used herein in its broadest sense to connote signals of whatever type, whether electronic, telephonic, radio, video, visual, aural, or otherwise palpable form,
- the monitoring system provides wide and flexible capabilities. Various other conditions in addition to pressure can be sensed by the system, such as supply level, liquid level, equipment or zone or fluid temperature, and equipment operation status or other attributes which may need to be monitored as to values or specific functions.
- a parameter e.g., pressure
- a parameter e.g., pressure
- sensing must take place and, if needed, an alarm given locally and/or optionally centrally communicated also; and for central monitoring it is necessary to know promptly the physical and/or data address of the alarm at the alarm point.
- the system provides such capabilities.
- the monitoring system uses one or more panels which at respective locations where one or more parameters such as gas pressures are to be monitored.
- Each such location or alarm point or monitoring point will have a unique address signifying location, as associated with a specific transducer sensing a parameter such as a condition or variable at a location.
- the monitoring system may optionally allow a healthcare facility to monitor centrally many such monitoring panels, such as up to 256
- the monitoring system is also capable of rapidly recognizing the existence of an out-of-limit condition from one of the separate monitoring panels, showing the type of alarm (whether being an out- of-limit condition or an actual alarm) , the nature of the out-of- limit condition, such as underpressure or overpressure, and the address of the monitoring panel from which the information is being transmitted.
- PCB Printed circuit board
- Each panel is a single entity device or unit providing an assembly of grouped modular configuration for monitoring gas source lines for multiple parameters, such as pressure, temperature, etc.
- the panels can be located throughout a healthcare or laboratory or clinic or other facility with capability for communication with a central facility having a personal-type computer (PC) .
- Specific modules for each panel may have interrelated functions, providing capability for monitoring gas pressures or vacuum lines, and signaling in response to changes in such pressures or relative pressures.
- a plurality of different gas variables or lines, and switch inputs can be monitored for signaling and/or alarm purposes, thereby avoiding the need for burdensome multiplication of sensors and alarms as additional variables or lines which might later require monitoring after installation of the monitoring system.
- the monitoring system is thus readily expandable whether at the panel locations or in the overall sense.
- the monitoring system may vary in size according to the facility in which it is installed, e.g., whether it be a hospital complex, or a small clinic, the monitoring system is designed and constructed according to a modular design philosophy in order to allow monitoring modules, including PCBs and components thereof, to be selectively configured and then selected for different uses in the monitoring system. In that way the monitoring system facilitates flexible growth.
- PCB design is shared by different modules, and -identical PCBs can be readily configured with different circuit elements according to the purpose required of the PCB for constructing a specific module.
- a monitoring system achieves a universality or interchangeability of circuit design features. Economy, efficiency, lowered manufacturing cost, and extraordinary performance and reliability are gained from this novel design philosophy in the monitoring system.
- a monitoring system with features designed to monitor the status of piped medical gases, including WAGD lines, and the respective delivery pressures of each gas or relative vacuum; which is capable of providing an alarm or otherwise signaling or providing communication upon the occurrence of a predetermined variance of a variable or parameter from a preset set point; which is capable of reporting such conditions to a central monitoring facility; which is useful to alert system users to situations that may cause personal injury or jeopardy, or equipment damage; which is capable of modem telecommunication of other out-of-limit conditions; which is capable of responding to further alarm or out-of-limit conditions even after an initial fault is detected; which includes self-test features to ensure proper operation; which provides visual
- Inventor: Kroupa et al . Attorney Docket Mo .: 11280-88027 display features which give rapid visual indication of relative levels or values being monitored so as to give the user quick assessment of conditions; which is capable of detecting and giving warning of discrete conditions such as normal, abnormal, "in use” and “out of use” which are being sensed; which operates safely over a wide variety of operating conditions; which provides high accuracy of operation over a wide range of possible variables or parameters being sensed; and which is capable of quick, safe, reliable and economic installation; and which is economically and reliably configured; and which may be expanded as may be required.
