Disclosed are automated urinary output ('UO')-measuring systems and methods. An automated UO-measuring system can include a container configured to collect a fluid such as urine. The container can include a console, one or more ultrasonic sensors coupled to the console for determining a fluid level within the container, one or more accelerometers coupled to the console for determining a near-zero acceleration state of the container for the determining of the fluid level within the container, and a valve configured to pass fluid therethrough by way of a fluid line coupled to the valve. The automated UO-measuring system can also include a container holder. The container holder can have a pocket for holding the container and a sleeve for securing the container to a user. A method of the automated UO-measuring system can include a method of using the automated UO-measuring system to collect and measure urine output of the user.

Automated urinary output-measuring systems and methods

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.

Collapsible thin-walled valve for drainage control

Disclosed herein is a waste detection system. The waste detection system includes a pad configured to acquire a fluid sample excreted from a patient. The pad includes one or more layers and at least one microfluidic channel configured to receive therein the fluid sample. The waste detection system further includes an intake manifold in fluid communication with the at least one microfluidic channel, the intake manifold configured to receive the fluid sample, the intake manifold having one or more reagents configured to detect the presence of waste within the fluid sample excreted from the patient.

Waste detection system

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.

Automatic fluid flow system with latch connection

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.

Dynamic pressure response system and method for measuring residual fluid

Embodiments disclosed herein are directed to a dynamic response drainage and occlusion system configured to drain a fluid from a patient. The drainage system includes an input airflow device to provide airflow into the drainage lumen, a pressure sensor to measure pressure within the drainage tube, and an output airflow device to provide airflow out of the drainage tube. A controller including control logic configured to acquire pressure data from the pressure sensor, determine a running pressure rate-of-change from the acquired pressure data, compare the running pressure rate-of-change with a pressure rate-of-change defined by the control logic, and adjust an operating characteristic of at least one of the input airflow device and the output airflow device to move the running pressure rate-of-change toward the pressure rate-of-change defined by the control logic. The system further includes catheter occlusions systems to automatically protect the patient from pressure spikes within the system.

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.

Automatic fluid flow system with retractable connection

A lid adapter for coupling with a lid of a collection container where the lid includes an outlet vent. The lid adapter including a housing including a top surface and one or more side panels that are configured to couple with a top of the lid and a port coupled to the top surface and configured to rotate between a first position and a second position, wherein when the lid adapter is coupled to the lid and the port is in the first position, a fluid seal is established between a distal end of the port and the top of the lid surrounding the outlet vent thereby enabling fluid flow from the outlet vent and through the port. When the port is in the second position, the fluid seal is not established, and when the port is in the first position, the port is disposed perpendicularly to the top surface.

Disclosed herein is an automated urinary output measuring system. The automated urinary output measuring system includes an automated urinary output measuring device configured to be suspended from a rim of a sanitary hardware device and receive a volume of voided urine. The automated urinary output measuring device can include a receiving trough having an opening, a door configured to cover the opening in a fluid tight seal, the door coupled to the receiving trough by a hinge, and a lip extending from the receiving trough configured to detachably couple the automated urinary output measuring device to the sanitary hardware device. The system can further include an ultrasonic measuring system having a console coupled to one or more ultrasonic sensors, and a flushing mechanism coupled to the sanitary hardware device.

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 push-button actuated locking mechanism. Embodiments of the locking mechanism can include a latch and aperture engagement, a shelf and ledge engagement, or a track and channel engagement, or combinations thereof. The ring connector and load cell can include electrical contacts configured to engage along an axis that extends perpendicular to a surface on which the electrical contacts are disposed. This is believed to reduce wear on the electrical contacts, thereby extending the usable life of the system.
