  • Publication number: 20240102847
    Abstract: 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.

  • Publication number: 20240042120
    Abstract: Embodiments disclosed herein are directed to a dynamic pressure response system for fully automated clearing of dependent loops from a fluid drainage system. Fluid drainage systems include a flexible drainage tube providing fluid communication with a collection container. Dependent loops can form within the tube leading to pooling of urine and provide an increased risk in CAUTI. Dynamic pressure response systems can automatically detect the presence of dependent loops and provide a low-rate positive air pressure to clear the columnized fluid. Further, the system can automatically detect mixed fluid states when a noise level of pressure signals increases, the system can then provide high-rate positive air pressure to clear mixed fluid state liquid from the tube lumen.

  • Publication number: 20220193366
    Abstract: Embodiments disclosed herein are directed to a dynamic pressure response drainage system including control logic configured to enable measuring of residual fluid disposed within the drainage lumen. The residual fluid volume is measured by detecting the magnitude of the dynamic pressure response in the system containing the residual fluid when a sudden displacement (e.g. increase or decrease) of air volume occurs inside the system. The pressure burst magnitude is related to the pressure needed to move the mass of fluid, thus the fluid volume can be calculated from measurements of the burst pressure. The magnitude of the measured air pressure exhibits a dynamic pressure response corresponding to the mass of fluid in the tube. Either positive or negative pressure bursts can be used to produce and measure the corresponding positive or negative dynamic response spike pressure.

The fluid collection assembly includes a fluid impermeable barrier that defines at least a chamber and at least one porous material disposed in the chamber. The tensioning element of the fluid collection system is configured to switch from a relaxed state and a tensioned state. The tensioning element is in the relaxed state when substantially no external tensile force is applied thereto and the tensioned state when an external tensile force is applied thereto. The tensioning element is configured to change a curvature of at least a portion of the fluid collection assembly, for example, by switching the tensioning element between the relaxed state and the tensioned state.
