Disclosed herein is an uroflowmeter which includes: a sensor having a signal transmitter transmitting an input signal to a detection area and a signal receiver receiving an echo signal reflected from urine passing through the detection area; a signal processing unit calculating uroflowmetry data based on a difference between the input signal and the echo signal, the uroflowmetry data being data about a flow of the urine passing through the detection area; and a diagnosis unit diagnosing urinary disorders of a test subject by comparing the uroflowmetry data calculated by the signal processing unit with preset reference uroflowmetry data.

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.

A system and method for collecting operation data associated with a medical apparatus including an internal device implanted in a subject and an external device that is magnetically-coupled to and drives the internal device. The medical apparatus may be monitored to obtain raw data associated with the operation of the medical apparatus and one or more calculations may be performed on the raw data, wherein the raw data and/or calculated values may be associated with voiding frequency and voiding volume of the subject. A report may be generated from the raw data and/or calculated values. In addition, one or more signals may be sent to the external device and/or a docking station, or communicated by other means, to indicate to the subject that the operation of the medical apparatus should be altered.

A portable liquid collection device includes a liquid collector, a guide tube and a liquid collection tube. The liquid collector includes a flowing liquid hole and an anti-slip structure. The guide tube includes two ends, one end connects to the liquid collector, and the other end is in a needle-shaped structure and connects to the liquid collection tube. A gas channel and a liquid channel are disposed in a tube body of the guide tube. The guide tube is provided with an outer annular structure. The liquid collection tube includes a collection tube body and a collection tube cover. The collection tube cover includes a tube cover body and a blocking plug. A placing slot for placing the blocking plug is disposed between the top and the bottom of the tube cover body.

Devices, systems, and methods herein relate to predicting infection of a patient. These systems and methods may comprise illuminating a patient fluid in a fluid conduit from a plurality of illumination directions, measuring an optical characteristic of the illuminated patient fluid using one or more sensors, and predicting an infection state of the patient based at least in part on the measured optical characteristic.

A fluid container measurement system is disclosed. The fluid container measurement system is configured to suspend a load measurement assembly a distance above a support surface. The load measurement assembly houses a load cell and a measurement control circuit. The measurement control circuit is coupled to the load cell and configured to receive electrical signals indicative of a force imposed on the load cell. Electrical signals generated by the load cell indicative of the force exerted on the load cell can be used to measure the fluid container attached to the load cell linkage member.

Disclosed are an apparatus for automatically measuring urine volume and a system for automatically measuring urine volume. The apparatus for automatically measuring urine volume of the present disclosure includes a urine container to which a urine catheter is connected, wherein an insertion hole is formed in an upper portion of the urine container, a hollow tube inserted into the insertion hole in a gravity direction, a floating body inserted into the hollow tube so as to move up and down and having buoyancy to float on the urine, and a distance sensor provided at an upper portion of the hollow tube so as to measure a distance to the floating body, wherein the volume of urine in the urine container is measured by using a measurement of the distance sensor. According to the present disclosure, the apparatus for automatically measuring urine volume and the system for automatically measuring urine volume are configured to measure the correct volume of urine automatically and continuously, regardless of the tilt of a urine container, the weight of a Foley catheter, and the presence of a nurse who directly checks the urine volume, so as to accurately recognize a change in the volume of urine and anticipate a probable emergency situation based on the change in the volume of urine.

A system includes a urination data storage unit, an absorbent article information storage unit, a changeable time storage unit, and a changing schedule proposal unit. The changing schedule proposal unit includes a changing schedule computation unit and a changing schedule outputting unit. The changing schedule computation unit finds, on the basis of urination amount data and urination time instant data stored in the urination data storage unit, a total urination amount within a predetermined time period selected from changeable time instants stored in the changeable time storage unit, and performs, by comparing the total urination amount that has been found and the urine absorption capacity of an absorbent article, computation for finding the absorbent article or the predetermined time period such that the urine absorption capacity does not fall below the total urination amount.

In one example, a system includes an elongated body defining a lumen where the elongated body includes a proximal portion and a distal portion. An anchoring member may be positioned on the proximal portion of the elongated body. The system further includes a sensor located on the elongated body where the sensor may be configured to sense at least one flow parameter of a fluid within the lumen. In some examples, the system includes processing circuitry configured to determine at least one of a density parameter or a temperature parameter of the fluid in the lumen based on the sensed at least one flow parameter of the fluid.
