Systems, devices and methods for draining and analyzing bodily fluids are disclosed in which a drainage assembly is configured to prevent negative pressure build-up. The drainage assembly generally includes a catheter which may include a drainage lumen, a reservoir, a venting mechanism in fluid communication with the drainage lumen and a positive pressure lumen, and a controller. The venting mechanism may further include a valve which is configured to maintain a closed position, as well as a vent in fluid communication with the valve, where the venting mechanism is configured to inhibit wetting of the vent from fluid within the drainage lumen

A fluid therapy method for an ADHF patient includes setting a urine output rate desired threshold, setting one or more desired negative net gain rates, and optionally setting a total fluid loss goal. The urine output of the patient is monitored and fluid is automatically administered to the patient at increasing rates to equal to or approximately match the patient's increasing urine output rates until the patient's urine output rate reaches the set urine output rate desired threshold. Thereafter, fluid is administered to the patient at rates to achieve the set desired negative net gain rate until the fluid loss goal is reached. Thereafter, until the end of therapy, fluid is administered to the patient at rates equal to or approximately equal to the monitored urine output rates.

Example systems, catheters, and methods are disclosed for actively sampling a fluid. An example system includes a pump configured to pump fluid to direct the fluid a dissolved oxygen sensor and the dissolved oxygen sensor configured to output a signal indicative of an amount of dissolved oxygen in the fluid.

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.

A self-placeable external catheter is disclosed that includes a catheter body having at least a top side and a bottom, a wicking area disposed on the top side, a finger covering extending from the bottom side of the catheter body creating a cavity configured to receive a user finger, and an aperture formed in the bottom side of the catheter, wherein the wicking area receives urine such that the urine passes through the wicking area, through the catheter body and through the aperture. The catheter tubing may be inserted into the aperture such that the urine passes through the wicking area, through the catheter body and through the aperture into the catheter tubing. An opening of the cavity may face a proximal side of the catheter body and the wicking area may include gauze.

A Coude catheter insures proper drainage and reduces tissue damage by using a loop section having an open passageway positioned on a proximal end of the catheter to adjust the catheter.

Examples relate to devices, systems, and methods for collecting and measuring discharged urine. A urine collection system includes a urine collection device configured to collect urine discharged from a user and a urine collection container in fluid communication with the urine collection device and sized and dimensioned to receive the urine discharged from the user. The urine collection system also includes a flow meter having a communication interface and positioned between the urine collection container and the urine collection device. The flow meter is configured to detect a flow property of the urine at least related to a volume of the urine entering the urine collection container and the communication interface is configured to wirelessly communicate to a computing device at least one of the detected flow property or the volume of the urine including the volume of the urine discharged from the user entering the urine collection container.

A device for rapid detection of a tuberculosis lipoarabinomannan (TB-LAM) is provided. The device includes a pre-concentrator unit for concentrating the TB-LAM comprising: an ion-exchange medium comprising one or more ligands configured to capture the TB-LAM from the source biological sample, wherein the captured-TB-LAM is eluted from the ion-exchange medium as an eluate comprising a concentrated form of TB-LAM; a cassette; a lateral flow assay unit disposed in the cassette; and an integration unit attached to the pre-concentrator unit and the cassette. The integration unit is configured to operatively couple and de-couple the pre-concentrator unit and the cassette. The pre-concentrator unit and the lateral flow assay unit disposed in the cassette are in a fluidic communication in a coupled form. The device for rapid detection of TB-LAM further comprises a dilutor unit.

An example device suitable for collecting and transporting urine away from the body of a person may include a fluid impermeable housing defining an internal volume. The device can include a porous material disposed within the internal volume. The fluid impermeable housing can define an opening in fluid communication with the internal volume. The porous material includes a contact surface and first and second sidewalls. The sidewalls can extend from the contact surface, for example, substantially orthogonal to the contact surface, or laterally and inwardly from the contact surface at an acute angle.

A system suitable for collecting and transporting urine away from the body of a person or animal may include an assembly having a fluid impermeable casing having a fluid reservoir at a first end, a fluid outlet at a second end, and a longitudinally extending fluid impermeable layer coupled to the fluid reservoir and the fluid outlet and defining a longitudinally elongated opening between the reservoir and the outlet. The assembly can further include a fluid permeable support disposed within the casing with a portion extending across the elongated opening, and a fluid permeable membrane disposed on the support and covering at least the portion of the support that extends across the elongated opening, so that the membrane is supported on the support and disposed across the elongated opening. The assembly can further include a tube having a first end disposed in the reservoir and a second, fluid discharge end.
