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.

Systems and methods for visualizing ablated tissue are disclosed.

Disclosed herein are apparatuses for manipulation of an ear device within the ear canal of a subject. Also disclosed herein are methods of using said apparatuses for the insertion, removal, or other manipulations of the ear device. Also disclosed herein are methods of making the apparatuses, and kits containing the apparatus with instructions for use.

The invention refers to a photonic integrated circuit (PIC), the photonic integrated circuit comprising: at least one laser, the laser having a laser output, a measuring portion including a measuring port and configured to measure an intensity and/or wavelength of light input at the measuring port, and an output portion configured to output light from the photonic integrated circuit to the portion of the tissue, wherein optionally the laser includes a ring resonator laser, a laser generating light having a fixed wavelength, a laser being constructed using hybrid integration, and/or a tunable laser.

The present invention relates generally to systems and methods for measuring an analyte in a host. More particularly, the present invention relates to systems and methods for processing sensor data, including calculating a rate of change of sensor data and/or determining an acceptability of sensor or reference data.

An energy balancing system scales portion sizes of user-selected meal recipes to control a digital scale to prompt the user to measure scaled quantities of meal ingredients to prepare scaled meals. Physical activity tracking devices provide data to generate physical activity energy expenditures for energy burned by physical activity. The physical activity energy is added to a basal metabolic rate of energy expenditure that is a function of sex, weight, height, and age. The total energy expended are scaled down for a weight-loss goal to obtain the total recommended energy. A recipe portion-size optimizer adjusts scaling factors for each recipe so that the total recommended energy is met by the scaled meals. Amounts of nutrients for the recipes can also be scaled by the scaling factors to match recommended nutrient amounts when the meal recipe optimizer generates the scaling factors using an over-determined linear system optimizer.

Disclosed is an electronic device comprising a processor and at least one sensor circuit comprising at least a biometric sensor and a fatigue sensor. The processor may be configured so as to detect biometric data of an external object by means of the biometric sensor, detect fatigue data of the external object by means of the fatigue sensor if the biometric data exceeds a designated second range, and output, by means of a designated external device, a fatigue notification indicating a fatigued state if the fatigue data exceeds a designated third range. Other various embodiments identified in the description are possible.

The present invention relates to an electrocardiogram measurement apparatus (measurement sensor) which can be used in combination with a smartphone by an individual. The electrocardiogram measurement apparatus according to the present invention comprises: two amplifiers for receiving electrocardiogram signals from a first electrode and a second electrode; one electrode driving unit; a third electrode for receiving an output of the electrode driving unit; an A/D converter connected to an output terminal of each of the two amplifiers and converting analog signals into digital signals; a microcontroller for receiving the digital signals from the A/D converter; and a communication means for transmitting the digital signal, wherein: the microcontroller is supplied with power from a battery; the microcontroller controls the A/D converter and the communication means; and each of the two amplifiers amplifies one electrocardiogram signal so as to simultaneously measure two electrocardiogram signals.

A cannula sensing system and method include a cannula having at least one biosensor configured to detect a level of one or more biomarkers in blood within a blood vessel of a patient. The biosensors are arranged at or near a distal end of a cannula inserted within the blood vessel. The biosensor may be connected to a wire arranged on and/or within a wall of the cannula.

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.
