Design of Manifold with Pressure Controller for Automatic Exchange of Oxygen Gas Cylinders in Hospital

Abstract

The regulation and supply of oxygen as one of the medical gases in the hospital is important to ensure the availability of these gases for the survival of patients. The regulation of oxygen gas in hospitals usually uses a piping system with manifolds. The manifold will monitor the oxygen gas pressure on each tube. Manifold systems that are widely used in general can only monitor pressure but cannot perform an automatic exchange on gas cylinders if the pressure is under the permissible conditions. The manifold system design developed is equipped with pressure monitoring for automatic exchange of oxygen gas cylinders using pressure sensors and microprocessors. The test results of the system using regulator and barometer comparisons showed the percentage value of sensor pressure accuracy of 96.92 percent and 97.16 percent. At pressure below the limit of 285 KPa manifold can perform the exchange of active gas cylinders automatically. These results show the manifold design built can work quite well.

Real-time stress detection and monitoring system using IoT-based physiological signals

“…One of the technologies used for health monitoring was the IoT [18]- [21]. The availability of this data, coupled with modern statistical analysis tools such as machine learning, can drive new standards of health diagnosis [19], [22], [23].…”

Relayout of oxygen filling area with seven waste method and green manufacturing analysis

“…Changes in inventory capacity have, of course, affected the storage locations for oxygen gas. Before the pandemic, the company utilized cradles or MCP (Manifolded Cylinder Pallet) for storing and delivering oxygen gas to the laser cutting machines at the company [2].…”

“…MCP (Manifolded Cylinder Pallet) is a collection of 16 gas cylinders with a capacity of 100-105 liters, all interconnected, filled or emptied together, and loaded and unloaded as a single unit. Manifold Cylinder Pallets are used in applications or industries where high volumes of gas need to be continuously supplied at regular flow rates and pressures, without interruptions [2]. In such applications or industries, the use of individual gas cylinders can be highly undesirable due to the time wasted in cylinder changeover, cylinder Available online at: http://jurnal.untirta.ac.id/index.php/jiss…”

Designing Prototype of Volume Detector for Medical Oxygen Cylinder Using NodeMCU ESP8266

“…The existence of a backup cylinder (secondary cylinder) also needs to be used as a substitute for oxygen supply to the patient if the main cylinder has run out. However, a gas pressure detection mechanism is needed in the main tube, in the form of a manifold system found in the oxygen cylinder [9].…”
