摘要： Embodiments disclosed herein are directed to apparatus and methods for automatic fluid flow system connectors. The system generally includes a load cell interface coupled to a console and a ring connector coupled to a fluid collection system. The ring connector can be releasably engaged with the load cell using a bayonet locking mechanism. One of the ring connector or the load cell can include a plate transitionable along a transverse axis between an engaged position and a disengaged as the ring connector rotates about a transverse axis. The plate can include electrical contacts configured to engage along the transverse axis and mitigate wear and damage to the electrical contacts, extending the usable life of the system.

摘要： Embodiments disclosed herein are directed to a connector for a fluid drainage having a body defining a drainage lumen extending longitudinally from a distal portion to a proximal portion. The body can include a piston housing and an inlet in fluid communication with a positive air pressure source. A piston is slidably engaged with the piston housing along a transverse axis between a first position and a second position. In the first position, the piston provides fluid communication between the distal portion and the proximal portion of the drainage lumen and occludes fluid communication between the inlet and the drainage lumen. The piston in the second position occludes fluid communication between the distal portion and the proximal portion of the drainage lumen and provides fluid communication between the inlet and the drainage lumen to clear dependent loops, while preventing distal fluid flow into a catheter.

摘要： A drainage system includes a vacuum chamber to receive drainage liquid from a drainage tube. The chamber can include an input port coupled with the drainage tube and a drain port coupled with a collection container. The system can include an air pump having an input coupled with a vacuum port of the vacuum chamber and a distal end of the drainage tube. Activation of the air pump can establish circulating fluid flow between the drainage tube and the vacuum chamber, and deactivation of the air pump can permit drainage liquid to drain from the vacuum chamber into the output tube. Also disclosed is a method of draining liquid from a patient, including accumulating a volume of the drainage liquid at a first location along a drainage pathway, moving the volume to a second location, accumulating the volume at the second location, and moving the volume to a collection container.

摘要： Embodiments disclosed herein are directed to a drainage control system including, a tubular body with a tubular body lumen extending from a distal end to a proximal end and a collapsible tube disposed within the tubular body lumen, the collapsible tube including a collapsible tube lumen extending from a distal end to a proximal end of the collapsible tube. The collapsible tube can be attached to the tubular body, such that fluid flow through the tubular body lumen flows through the collapsible tube lumen. The tubular body can include a valve that is actuatable between a first configuration wherein fluid flow is allowed through the tubular body lumen and a second configuration wherein fluid flow is prevented through the tubular body lumen. An airflow source can be coupled to the valve such that pressure from the airflow source actuates the valve.

摘要： Embodiments disclosed herein are directed to apparatus and methods for automatic fluid flow system connectors. The system generally includes a load cell interface coupled to a console and a ring connector coupled to a fluid collection system. The ring connector can be releasably engaged with the load cell using an engagement structure such as a latch, locking arm, or spring clip mechanism. The ring connector and load cell can include electrical contacts configured to engage along an axis that extends perpendicular to a surface that the electrical contacts are disposed on. Advantageously, reduced wear on the electrical contacts should extend the usable life of the system.

摘要： An automatic fluid flow measuring system for detecting a fluid weight change of a fluid collection system includes a load cell configured to detect a downward force and a ring connector configured to releasably couple to the load cell. The load cell can include a plate movable along a transverse axis orthogonal to a face of the plate. The plate can include a first electrical contact. The ring connector is configured to transition between an unlocked position and a locked position on the load cell. The ring connector can include a second electrical contact configured to communicate with the first electrical contact in the locked position.
