An ear thermometer capable of identifying an infrared transmittance of a probe cover is provided and includes an ear thermometer body, a probe, and a plurality of activation elements. The probe is disposed on the ear thermometer body. A closed end of the probe cover is used for infrared transmittance, and the probe cover has different infrared transmittances according to a thickness variation thereof. The activation elements are disposed on the ear thermometer body and configured to detect the infrared transmittance of the probe cover. Each of the activation elements includes an ON state and an OFF state so that the activation elements are arranged to form different sensor combinations, which respectively correspond to different infrared transmittances, and any two of the different sensor combinations have the two corresponding infrared transmittances that are different from one another.

The present invention comprises a novel kit with a wearable unit along with associated intelligent entities and non-intrusive tremor relieving interventions. The interventions include an automatically controllable TENS intervention unit with associated cables and electrodes and a buzzer. The wearable unit along with associated intelligent entities detects involuntary movement signals (tremors) in the limbs by measuring the acceleration in multiple dimensions, and ingeniously analyzes the accelerations to identify and isolate occurrences of tremors. This information is analyzed and monitored over time to provide significant insight about the tremors such as the dominant frequency (or frequencies), percent time with tremor, median tremor duration, and intensity. The TENS unit provides electrical stimulation which can dampen the intensity of involuntary movement and/or temporarily suspend tremor activity. This (TENS) unit can be manually or automatically controlled. The automatic control mode controls the TENS unit depending on the onset of tremors, tremor duration, and intensity of tremors. Furthermore, the parameters of this automatic control can be adjusted.

A method for determining oxygen saturation includes emitting light from sources into tissue; detecting the light by detectors subsequent to reflection; and generating reflectance data based on detecting the light. The method includes determining a first subset of simulated reflectance curves from a set of simulated reflectance curves stored in a tissue oximetry device for a coarse grid; and fitting the reflectance data points to the first subset of simulated reflectance curves to determine a closest fitting one of the simulated reflectance curves. The method includes determining a second subset of simulated reflectance curves for a fine grid based on the closest fitting one of the simulated reflectance curves; determining a peak of absorption and reflection coefficients from the fine grid; and determining an absorption and a reflectance coefficient for the reflectance data points by performing a weighted average of the absorption coefficients and reflection coefficients from the peak.

Ultrasound imaging systems for automatically identifying and saving ultrasound images relevant to a needle injection procedure, and associated systems and methods, are described herein. For example, an ultrasound imaging system includes a transducer for transmitting/receiving ultrasound signals during a needle injection procedure, and receive circuitry configured to convert the received ultrasound signals into ultrasound image data. The image data can be stored in a buffer memory. A processor can analyze the image data stored in the buffer memory to identify image data that depicts a specified injection event of the needle injection procedure, and the identified image data can be stored in a memory for archival purposes.

The apparatus has a control unit, a connection unit and a vibration unit. The connection unit has a control-element-side region, an edge region and a flexible region, wherein the control-element-side region is flexibly mounted relative to the edge region by the flexible region.

The control unit is configured to generate a contact signal based on contact with the contact region. The vibration unit is configured to induce a vibration of the contact region relative to the edge region during contact with the contact region.

A system for targeting a feature on a surgical device, includes a shape sensing element coupled to an interrogator and operable to provide information to related to said portion's position in a reference frame in communication with the targeted feature. The interrogator is operable to poll the shape sensing element for information related to said portion's position in the reference frame. A surgical tool is coupled to the targeting system in communication with the shape sensing element. The data processor is operable to communicate with the interrogator to output position information of the portion of the shape sensing element with respect to a calibrated position, defined as the position of the portion of the shape sensing element in the reference frame when the guide axis is aligned to the targeted feature. A display provides the user visual information comparing the position of the tool to the targeted feature.

A photoplethysmographic (PPG) device is disclosed. The PPG device can include one or more light emitters and one or more light sensors to generate the multiple light paths for measuring a PPG signal and perfusion indices of a user. The multiple light paths between each pair of light emitters and light detectors can include different separation distances to generate both an accurate PPG signal and a perfusion index value to accommodate a variety of users and usage conditions. In some examples, the multiple light paths can include the same separation distances for noise cancellation due to artifacts resulting from, for example, tilt and/or pull of the device, a user's hair, a user's skin pigmentation, and/or motion. The PPG device can further include one or more lenses and/or reflectors to increase the signal strength and/or and to obscure the optical components and associated wiring from being visible to a user's eye.

A medical imaging binocular indirect ophthalmoscope with computational processing unit, enabling simultaneous or time-delayed viewing and collaborative review of photographs or videos from an eye examination. The invention also claims a method for photographing and integrating information associated with the images, videos, or other data generated from the eye examination.

Various embodiments enable calibrating a non-invasive blood pressure measurement device by determining multiple parameters defining a stress-strain relationship of an artery of a patient. The device may obtain output signals from a blood pressure sensor at two or more measurement elevations. The obtained measurement signals may be filtered into AC and quasi-DC components, and results fit to exponential functions to calculate an arterial time constant and a veinous time constant related to vein draining/filling rates. The arterial and veinous time constants may be used to calculate an infinity ratio. The infinity ratio and the obtained sensor output may be used to calculate values for multiple parameters defining a stress-strain relationship of a measured artery. Once defined, this stress-strain relationship may be stored and applied to future sensor output signals (e.g., blood pressure measuring sessions) to infer patient blood pressure.
