The tube is adapted to provide minimal restrictions on the flow of the breath sample. The device also includes an oxygen sensor and carbon dioxide sensor disposed partially within the tube and adapted to detecting an amount of oxygen and carbon dioxide present in the breath sample respectively. The device also includes a controller adapted to receive data from the oxygen sensor and the carbon dioxide sensor.

A pulse oximetry system for reducing the risk of electric shock to a medical patient can include physiological sensors, at least one of which has a light emitter that can impinge light on body tissue of a living patient and a detector responsive to the light after attenuation by the body tissue. The detector can generate a signal indicative of a physiological characteristic of the living patient. The pulse oximetry system may also include a splitter cable that can connect the physiological sensors to a physiological monitor. The splitter cable may have a plurality of cable sections each including one or more electrical conductors that can interface with one of the physiological sensors. One or more decoupling circuits may be disposed in the splitter cable, which can be in communication with selected ones of the electrical conductors. The one or more decoupling circuits can electrically decouple the physiological sensors.

Embodiments described herein are directed to an automatic catheter measurement system for determining a length of a catheter required to extend between an insertion site and a target location, prior to placement of the catheter. The system can include a measurement device that can be aligned with, and map, a three-dimensional arrangement of one or more external landmarks. The measurement device can include magnetic and/or fiber optic systems to map the external landmarks. The system then determines a framework to provide a predicted catheter length required to extend between the insertion site and target location. The measurement device can also be included with the catheter during placement to confirm the actual catheter length and improve the accuracy of future predicted frameworks.

Systems, devices, and methods for a dual analyte sensor using glucose history from a glucose sensor in combination with data from a ketone sensor to control operation of a user interface device or insulin pump are provided. In some embodiments, the systems, apparatus or methods may make use of combination of glucose history and a ?-hydroxybutyrate physiological model to better predict diabetic ketoacidosis (DKA), in comparison to a prediction based on a simple high glucose threshold. In other embodiments, the systems, apparatus or method may include features for generating an estimate of the patient's medication state and/or knowledge of medication information, such as a patient with T1 diabetes mellitus (DM) using an SGLT-2 inhibitor.

The present invention provides a smart wearable IOT device configured to be worn by a subject on the body and is capable of continuously tracking and reporting a plurality of vital signs and physical activities of the user, including but not limited to sound and vibrational dynamics due to breathing and coughing (from which we can derive the breathing and coughing types and features), body temperature, peripheral oxygen saturation (SpO2), heart rate, and fatigue-related mobility, physical ability, step count, photoplethysmogram (PPG), ECG, heart rate, heart rate variability, etc. In one aspect, the wearable system will be able to measure the distance with different users through the transmit and receive of Bluetooth low energy signals or WiFi to trace contacts between different wearers. The system will be able to record the data locally on a SD card and also will be able to upload on a server.

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 has a contact region, wherein the contact region is fixed relative to the control-element-side 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.

An automated allergy office system and method provides a medical professional with a new allergy treatment plan to administer to a patient. The automated allergy office system comprises a viewing device to select a test site on the patient's skin that is clear. A multiple test applicator is in cooperative engagement with a fluid tray and delivers a small amount of a first allergen to a first test site on the patient's skin as a small amount of a second allergen is delivered to a second test site on the patient's skin. The allergy condition of the patient is detected as a wheal forms at the first test site after fifteen minutes. The elements of the treatment plan are retrieved from a database for treating the patient's allergy condition. The patient's electronic medical record is checked to confirm that the allergy treatment is new for this patient.

A method of quickly and effectively treating cervical vertigo by using EMG-guided injections of botulinum toxin into selective dystonic neck muscles. For each treatment, EMG-guided injections are used wherein an EMG needle is injected into the muscle. An EMG test is then performed using the EMG needle to determine if the muscle is overactive. If the muscle is overactive, a measured amount of botulinum toxin is administered into the muscle using the EMG needle. Muscles that are not overactive are not administered botulinum toxin. The above procedure is conducted in various neck muscles, such as the oblique capitis superior muscle, the oblique capitis inferior muscle, the longissimus capitis muscle, the trapezius, and the levator scapula.

The present invention relates to a device for measuring a physiological parameter of a human limb such as peripheral capillary oxygen saturation. The device comprises a body comprising an opening for receiving the limb therein, a moving means coupled to the body and movable relative to the body, a receiving element for receiving a sensor configured for interacting with the limb received in the opening, wherein the body comprises a first section and a second section movable relative to the first section for defining the opening, wherein the moving means is coupled to the second section so as to adjust the size of the opening by moving the moving means.
