The invention relates to a spirometer (1) comprising a MEMS-based thermal fluid flow sensor (13, 13.1, 13.2) for generating a signal in response to a fluid flow generated during inhalation or exhalation; and a microcontroller (14) for calculating the fluid flow from the signal generated by the flow sensor (13, 13.1, 13.2). The spirometer (1) may be connected to other devices, such as a smartphone or a personal computer or any other computing unit which is adapted to collect, store, analyse, exchange and/or display data. The invention further describes the use of the spirometer (1) in measuring a user's lung performance and/or monitoring it over time. Furthermore, the spirometer (1) may be provided in a system together with an air quality measurement device for determining the air quality at a location of interest; and a computing unit for collecting, analysing and correlating the user's lung performance data obtained from the spirometer (1) with the air quality data, and optionally geolocalisation data of said location.

A mouth guard senses impact forces and determines if the forces exceed an impact threshold. If so, the mouth guard notifies the user of the risk for injury by haptic feedback, vibratory feedback, and/or audible feedback. The mouth guard system may also remotely communicate the status of risk and the potential injury. The mouth guard uses a local memory device to store impact thresholds based on personal biometric information obtained from the user and compares the sensed forces relative to those threshold values. The mouth guard and its electrical components on the printed circuit board are custom manufactured for the user such that the mouth guard provides a comfortable and reliable fit, while ensuring exceptional performance.

The wearable article 200 comprises a sensing component. The electronics module 100 is removably coupled to the wearable article 200. The electronics module comprises a housing and a processor disposed within the housing 101. An interface element 121, 123 interfaces with the sensing component so as to receive signals from the sensing component and provide the same to the processor. A sensor 105 is disposed within the housing 101. The sensor 105 monitors a property of the environment external to the electronics module 100 through the housing 101. The housing 101 is constructed such that the sensor 105 has line of sight through the housing 101.

A prosthesis for monitoring a characteristic of flow includes a first tubular prosthesis having a lumen and a sensor for detecting the characteristic of flow through the lumen. The sensor may be covered with another tubular prosthesis or by a layer of material in order to insulate the sensor from the fluid flow. A pocket may be formed between the tubular prosthesis and the adjacent layer of material or prosthesis and the sensor may be disposed in the pocket.

A body fluid analyte detection device, includes: a transmitter, provided with at least one first clamping part; a bottom shell, provided with a second clamping part corresponding to the first clamping part, the transmitter being assembled on the bottom shell by mutual snap fitting of the first clamping part and the second clamping part, the bottom shell including a fixing part and a force application part, and the fixing part being fixed and applying a force to the force application part in a direction to disable the bottom shell, so that the first clamping part and the second clamping part are separated from each other, and then the bottom shell and the transmitter are separated; a battery, used for supplying power to the transmitter; a sensor, used for detecting body fluid analyte parameter information and electrically connected to the transmitter to transmit a parameter signal.

A body fluid analyte detection apparatus is provided. Applying a force to a force applying portion of a bottom case in one direction can make the bottom case fail, and then separate the bottom case and a transmitter from each other. Before the bottom case is mounted to a human body, the bottom case is fixed together with a mounting unit by means of a snap-fit portion. Operation steps of a user when separating the bottom case from the transmitter are reduced, and the failure rate of the bottom case before being mounted to the human body is also reduced, thereby improving the user experience, and enhancing the reliability of the body fluid analyte detection apparatus.

Embodiments relate to an insertion device that includes: a plunger coupled with a lock collar. The insertion device houses contents including: a striker including self-locking striker snap arm(s) where the striker is kept from firing by a striker spring captured between the plunger and the striker when the insertion device is in a cocked position; a sensor assembly; and a needle carrier that holds a piercing member, the needle carrier captured between the striker and a needle carrier spring where a self-releasing snap(s) keeps the needle carrier cocked, where the plunger prevents the self-releasing snap(s) from repositioning and releasing the needle carrier. The striker fires the needle carrier such that the self-locking striker snap arm(s) are positioned to allow the striker to snap down. The needle carrier is then retracted when the user releases the plunger and the piercing member is encapsulated within the insertion device.

Described herein are systems, devices, and methods for energy-efficient operation of wireless devices. In some variations, a wireless monitor may comprise a sensor configured to measure a physiological parameter of a patient at a first resolution. A processor may be configured to generate physiological parameter data based on the measured physiological parameter of the patient at the first resolution. The sensor may be configured to measure the physiological parameter of the patient at a second resolution based at least in part on the physiological parameter data.
