A current sensor may take measurements of electrical currents that flow between two limbs of a patient through at least a portion of the patient's torso. The current measurements may be taken during a single diagnostic session while the patient holds a ground electrode in a hand of one limb and a probe electrode is sequentially placed at different locations on the distal portions of other limbs. Each of the measurement locations may be an acupuncture point. An electrical current state for the diagnostic session may be calculated. This state may consist of current ranges for one or more electrical currents that are measured during the session. A lookup table may be employed to determine one or more medical conditions that are indicated by the current state. Alternatively, a trained machine learning model may predict, based on the measured currents, one or more medical conditions.

The present invention relates to a 1- or 3-lead oral ECG device, shaped and implemented like a household digital thermometer. The 3-lead device comprises three contact electrodes: two contact electrodes on a body of the device, configured for contact with the left and right hands; and one contact electrode on a metallic tip of the device—which may comprise a thermometer—configured for contact with the mouth. The 1-lead device comprises any two of these three contact electrodes and a temperature sensor disposed in the metallic tip. A novel transformation of the three leads from the 3-lead device enables the ECG signals to be processed like a standard ECG that comprises a contact electrode in contact with the leg instead of the mouth. An oral ECG device of the invention may comprise other sensors, such as a pulse-oximetry sensor, respiratory rate sensor, skin temperature sensor, body impedance sensor, galvanic skin response sensor, and/or blood-flow sensor.

Apparatus for precisely locating a distal end of a Central Venous Access Device (CVAD) including a cardiac monitor having a display screen and a first electrical input and a second electrical input. A first electrical lead wire has a first end electrically connected to the first electrical input of the cardiac monitor, and a second end to be electrically connected to a left side of a patient's body. A stylet is included having a proximal end and a distal end, wherein a second electrical lead wire having a first end is electrically connected to the second electrical input of the cardiac monitor, and a second end on the second electrical lead wire, and a first Quickly Attached/Quickly Released (QA/QR) electrical connector is attached to the second end of the second electrical lead wire. The first QA/QR electrical connector is electrically connected directly to the proximal end of the stylet. The first QA/QR electrical connector preferably is a hook clip.

Systems and methods for a medical device are provided. The handheld medical device includes a housing including a front and rear side. A diaphragm is located in the center of the rear side of the housing. Three or less rear electrodes, configured to collect electromagnetic signals from the chest region of a patient, are located in a semi-circular in shape that encircles the diaphragm on the rear side of the housing. Two front electrodes located on the front side of the housing collect signals from the left and right index fingers of the patient. A screen is located between the two front electrodes. The device may include a transmitter, in some cases a Bluetooth module, for coupling the medical device to a user device. The user device includes an application that receives the signals and performs analysis on them. The five electrode inputs are used to calculate seven ECG channels.
