Abstract: An illustrative modular manifold system includes, among other things, two or more modular pump manifolds, a low-pressure header, and a main high-pressure manifold. Modular pump manifolds may include a low-pressure manifold for supplying fracturing fluid or water to pumps, a high-pressure manifold for supplying fracturing fluid or water to one or more wells and a bleed-off/prime-up manifold. Each modular pump manifold of the modular manifold system is configured to be fluidly isolatable from the other modular pump manifolds. Each isolated modular pump manifold is configured to be flushed with water, bled off and primed up independently of the other modular pump manifolds. After the bleed off, maintenance procedures may be performed on pumps associated with the isolated modular pump manifold. The modular pump manifolds that are not isolated may continue in active fracing stage operations while a modular pump manifold is isolated.

Abstract: A system may have a built hydraulic fracturing system with a plurality of devices connected together and in fluid communication with one or more wells. The system may also include at least one continuous pumping operations for one or more wells and a fracturing pumping plan provided on a software application. The fracturing plan may include instructions to perform at least one continuous pumping operations for the one or more wells. The instructions may include a sequence of valve operations to direct fluid flow through a selected path into the one or more wells.

Abstract: A vacuum regulator apparatus for continuous subglottic aspiration is provided. In one version, the regulator apparatus attaches to a standard vacuum regulator and shares the same vacuum supply outlet as the standard vacuum regulator. Sufficient airflow is provided through the regulator apparatus and calibrated bleed orifice to provide proper continuous subglottic aspiration. Vacuum levels to maintain the airflow are in a range suitable to provide patient comfort. A ball flow indicator provides visual indication of flow through a subglottic tube interface port of the regulator apparatus. A direct flow channel can be momentarily opened causing flow to bypass the regulator module in for clearing blockages affecting the subglottic tube interface port.

Abstract: A vacuum regulator includes two gauges, such as an electronic gauge and a mechanical gauge, each adapted to take a measurement associated with a vacuum. A digital display is associated with the electronic gauge, and an analog display is associated with the mechanical gauge. The displays are secured in relative proximity to each other and oriented to enable a user of the regulator to obtain a reading corresponding to the vacuum from either of the displays.
