The embodiments described herein relate generally to medical devices that measure vital signs, and more particularly to wearable wireless devices that collect multiple simultaneous vital signs, and systems and methods for compressing the sensor data into a matrix representation to facilitate collecting, transmitting, processing, and displaying vital sign data.

A continuous analyte meter may include an electrochemical sensor invasively inserted into the skin, a transmitter including a main substrate to which a battery is connected and a housing in which the main substrate is accommodated, the housing being attached to the skin and the main substrate controlling a signal measured by the electrochemical sensor, a needle inserting the electrochemical sensor into the skin, and an inserter provided with an actuator that moves the transmitter and the needle from a first position to a second position so that the needle penetrates the skin or retracts the needle from the second position to a third position.

Methods, devices, systems, and kits are provided that buffer the time spaced glucose signals in a memory, and when a request for real time glucose level information is detected, transmit the buffered glucose signals and real time monitored glucose level information to a remotely located device, process a subset of the received glucose signals to identify a predetermined number of consecutive glucose data points indicating an adverse condition such as an impending hypoglycemic condition, confirm the adverse condition based on comparison of the predetermined number of consecutive glucose data points to a stored glucose data profile associated with the adverse condition, where confirming the adverse condition includes generating a notification signal when the impending hypoglycemic condition is confirmed, and activate a radio frequency (RF) communication module to wirelessly transmit the generated notification signal to the remotely located device only when the notification signal is generated.

A wearable device assembly has a housing supporting a controller, display and indicator system thereon. The controller has at least one sensor wherein activity of a user wearing the device is detected. The controller selectively illuminates the indicator system to indicate a level of activity of the user.

A system uses continuous tracking of sleep activity and heart rate activity to evaluate heart rate variability immediately before transitioning to an awake state, e.g., at the end of the last phase of deep sleep. In particular, a wearable, continuous physiological monitoring system as described herein includes one or more sensors to detect sleep states, the transitions between sleep states, and the transitions from a sleep state to an awake state for a user. This information can be used in conjunction with continuously monitored heart rate data to calculate heart rate variability of the user at the end of the last phase of sleep preceding the user waking up. By using the history of heart rate data in conjunction with sleep activity in this manner, an accurate and consistent recovery score can be calculated based on heart rate variability.

A wearable device assembly has a housing supporting a controller, display and indicator system thereon. The controller has at least one sensor wherein activity of a user wearing the device is detected. The controller selectively illuminates the indicator system to indicate a level of activity of the user.

A removable wrist device in a continuous physiological monitoring system includes a mounting fixture with a pair of rails to securely retain another device, such as a battery, a watch, or a display. The rails may be curved to secure the device against displacement during purely translational movement while conveniently conforming to the shape of a wrist. At the same time, the rails can permit movement around the axis of the wrist (where significant rotational forces are not regularly encountered) to permit convenient attachment and removal of the other device to the wrist-mounted device through a rotational, sliding motion. This configuration provides an advantageous combination of ease of use (sliding on and off in a natural motion), mounting tenacity, and comfort.

A masked etching process can prepare patterned nanocellulose for use in conformal electronics such as electrodermal structures might be adhered to human skin.

The present application discloses a device (10), a system, and a method for monitoring the penile tumescence. The device comprises a loop (3) positioned around the base of the penis. The loop (3) consists of two string threads mutually attached on both ends. Said string threads are wound up on a reel (1) having the centrally positioned spring (la). The movement of the reel (1) and the rotation of the magnet (2) indicate the penis diameter and the intensity of the erection. The magnetic rotary encoder (5) outputs the digital form of acquired data to a microprocessor (6). The data are preferably forwarded over a BLE communication module (7) to the mobile app, installed on a smart device that communicates with a remote computer.

It is commonly known within the art of cutaneous/transcutaneous blood gas monitoring to warm up the skin of the patient to allow carbon dioxide and oxygen to diffuse easily through the skin. This is especially the case for transcutaneous partial pressure monitoring of oxygen. Heating the skin to 43 C. to 45 C. over several hours or days may cause damage to the skin. In order to avoid or minimize the risk of these damage, it is proposed to monitor the blood gases at a lower temperature with a cutaneous sensor, and intermittently warm up the skin to a temperature of 42 C. or more for a short duration to monitor the transcutaneous partial pressure of oxygen, before lowering the temperature to the lower set point.
