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.

Disclosed are a pulse meter and a control method therefor, aiming at solving the problem that a plurality of sensors in the existing pulse meter cannot fit well with the wrist surface. The pulse meter comprises a main body, a compression mechanism disposed on the main body, a plurality of pressure sensors (12) connected with the compression mechanism, and a controller (6) in communication connection with the compression mechanism and the pressure sensors (12). The compression mechanism comprises a compression airbag (21) and an air pump assembly connected with the compression airbag (21); the compression airbag (21), when inflated, can enable the plurality of presser sensors (12) to abut the wrist surface at approximately the same preset pressure. The described arrangement can enable the plurality of presser sensors (12) in the pulse meter to abut the wrist surface at approximately the same preset pressure, thereby enhancing the accuracy of collecting pulse manifestation, balancing the force on the wrist surface, and optimizing user experience.

The objective of the present invention is to provide a hardness meter which estimates hardness in a stable manner regardless of a compression strength. A hardness meter includes: a movable portion which is continuously pressed against an object to be measured; a sensor which outputs an output signal reflecting a reaction force at a part of the object to be measured; a motive force mechanism that causes the movable portion to perform a piston motion; a hardness estimating portion which estimates the hardness of the object on the basis of an alternating current component of the output signal, generated by the piston motion; a position estimating portion which estimates a measurement position information by shooting with a camera; and a hardness map display portion which maps and displays the hardness on a schematic diagram of the surface of a living body based on the measurement position information.

An apparatus includes a wearable sensor structure that includes multiple individual sensor units placed in a row. Each individual sensor unit includes a first portion to contact a surface of skin under which arteries and/or veins are to be located, and a second portion that contacts the first portion and is configured to have a capacitance. The first and second portions are configured to create a capacitance change in response to a squeezing or bending between the first portion and a fixed part of the second portion caused by a pulse pressure and release of the pulse pressure. The apparatus includes circuitry configured to measure waveforms for the individual sensor units. Each waveform captures the capacitance change for its corresponding individual sensor unit. The apparatus includes a wireless interface configured to transmit the waveforms. A computing system is also disclosed that analyzes the waveforms and can provide alerts based thereon.

A method for solid water particle treatment of eye, ear, and nose ailments detects and treats ailments in the eyes, ears, and nose through a procedure of capturing infrared images of the Meridian pathway near the eyes, ears, or nose, and then administering a solid water particle solution to help repair the Meridian pathway. The efficacy of the solid water particle solution is determined by capturing an initial image and a subsequent image of the Meridian pathway near the eyes, ears, or nose. The skin temperature of both images is visually indicated in a thermal coloring or white-hot spot. If the temperatures detected in the subsequent infrared images decrease, the Meridian pathway of the eyes, ears, or nose is improving. Thus, the status of the eyes, ears, or nose is determined based on changes in skin temperature at the Meridian pathway approximate to the eyes, ears, or nose.
