Disclosed herein are medical devices, systems, and methods for collecting urine output from a patient, generally including a urine receiving device and a collection container coupled with the urine receiving device. Collection devices described herein can automatically determine collected urine volume, and also automatically determine protein content, salt content and pH of the collected urine. Collection devices can automatically display different colors according to collected volumes of urine. Some devices can determine the volume of urine within a patient's bladder. Systems can include a bladder volume device and logic to facilitate communication with external entities. Some systems may also include a urine collection device. Urine receiving devices can include external catheters.

In some examples, a device includes a catheter insert elongated body defining a body lumen, the catheter insert elongated body being configured to be at least partially inserted to a catheter lumen defined by a catheter without covering a first fluid opening of the catheter and to form a fluidically tight coupling with the catheter, and one or more sensors positioned on the elongated body. At least one of the one or more sensors are configured to sense a substance of interest. The catheter insert elongated body includes a material that is a substantially non-permeable to the substance of interest.

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.

A biological function estimation device includes a processor configured to predict a drug reaction in a patient based on an evaluation value obtained by evaluating a biological function of the patient from a test result before drug administration and data on a drug to be administered to the patient, and configured to correct the evaluation value according to a comparison result between an obtained prediction value and a measurement value obtained by measuring the drug reaction after the drug administration.

A device includes: housing having top surface, bottom surface, and at least one side surface connected between top surface and bottom surface; a load cell positioned within housing; flexible section positioned within at least one of bottom surface or top surface of housing; rigid section positioned within flexible section, rigid section having opening surrounded by rigid material; rigid support having first end, second end, and center section; wherein first end of rigid support is positioned within housing and coupled to load cell; and wherein center section of rigid support passes through opening in rigid section positioned within flexible section, wherein center section of rigid support contacts rigid material of rigid section surrounding opening, wherein second end of rigid support is outside of housing.

A health monitoring urinalysis system that monitors several health indicators from human urine is provided. The system includes a temperature sensor and several electrochemical sensors that are installed in a urine collection basin, such as, a toilet or a urinal and may automatically collect urine information after each use. The system collects data during the routine and normal use of a urine collection basin. The system includes a control and measurement unit that may be installed outside the urine collection basin. The control and measurement unit receives sensor measurements and transmits the measurements to one or more remote electronic devices. The remote electronic devices and/or the processor of the control and measurement unit perform data analysis, provide diagnostic, and generate health alerts. The system performs recurrent health monitoring after the urine collection basin is used and may detect abnormal conditions at early stages, in addition to a routine urine test.

A urinary catheter can be retained inside the body for extended periods. A catheter mating device can connect to the catheter to move the catheter inside of the body or remove it from the body. The catheter includes: (1) a tube having a lumen and an outer surface, (2) a retainer that may have an attachment portion attached to the tube and a flap or handle-shaped structure attached to the attachment portion, wherein the retainer has a first, contracted position and a second, extended position, and (3) an bladder retention structure at the catheter's distal end, wherein the bladder retention portion may comprise a flap or a handle-shaped portion and that has a first, compressed position and a second, extended position. The retainer and/or bladder retention structure each are configured to retain the catheter in the proper position inside of a user's body.

A retrofittable commode attachment device that automatically measures and charts electronically one or more types of health data. The device includes a base platform with a back portion, a left side portion, a right side portion and a front portion, a plurality of load cells on the left side of the base platform and a plurality of load cells on the right side of the base platform, at least one microphone, at least one camera, and at least two commode connector brackets that engage the horizontal support of a commode and the base platform is positioned below the toilet seat of the commode and is not part of the toilet seat.

Systems, apparatuses, and methods for detecting and quantifying a fluid are described herein. In some examples, a sensor apparatus is used to absorb discharged fluid (or other fluid present). The sensor apparatus includes one or more sensors designed to provide a capacitance measurement using electrodes in the sensors and one or more fluid properties sensors that determine at least one fluid property of an absorbed fluid. The electrodes are designed using mirror image axes of deformation to minimize the effect of deformation caused by the wearer of the sensor while still allowing some degree of flexibility for comfort. The person wearing one or more of the sensors may be monitored and cared for remotely using a communication system between the local device and a remote device used by a caregiver or medical practitioner.

The test lab set-up includes a test flow bench for mounting one or more test devices, an adjustable nozzle for simulating urine flow, and a sensor for collecting data associated with the simulated urine flowing through the test device(s). A computing device for measuring and/or calculating various parameters associated with the simulated urine flow may also be included. The test device may have a shape corresponding to a handheld uroflowmeter subject to testing. The angle of the adjustable nozzle may be adjusted to test for various angles of urine flow. Similarly, the angle, pitch, and roll of the test device may be adjusted to test for various angles at which a uroflowmeter is held. As fluid flows through the test device, the sensor collects information such as, for example, flow rate, duration, volume, and the like. The sensor transmits the data collected to a computing device for additional processing.
