Problems solved by technology

[0003] But in reality, all kinds of bioelectric measuring instruments have a single measurement function, such as electrocardiograph, electroencephalograph, myograph, oculograph (including retinal electricity and nystagmus), gastric electricity, etc., which cannot perform various functions of the human body. This kind of synchronous measurement of bioelectricity can only be used in hospitals. General practitioners are generally all-rounders who deal with common diseases, frequently-occurring diseases and general emergencies in the form of outpatient clinics. Due to the particularity of the general practitioner profession, it is urgent to develop Practical needs for bioelectricity meters

Embodiment Construction

[0015] 1. Bioelectric parameters and measurement range

[0016]

[0017] 2. Bioelectric measurement electrodes

[0018] Bioelectricity measurement is usually made of some kind of processed metal plate, metal fine needle or metal mesh. Whether the performance of the measurement electrode is good or not will directly affect the measurement results of various biopotential changes.

[0019] In practice, when the electrode measures the biopotential change, it is usually regarded as an energy conversion process from ionic conduction to electronic conduction on the electrode-dielectric interface, and the electrical performance of the electrode is equivalent to the capacitance, resistance and semi-conductivity. Equivalent circuit composed of battery potential.

[0020] 3. EEG measurement implementation

[0021] For EEG measurement, a pair of electrodes is used to measure the potential difference between the two electrodes in the bipolar lead mode. The calibration (calibration) vo...

Abstract

The invention discloses a bioelectricity measurement apparatus for general medical practitioners. The bioelectricity measurement apparatus comprises electrodes (1), a signal conditioning circuit (2), a data acquisition card (3), an apparatus driver (4), panel program (5), application program (6), a virtual apparatus development platform (7), a portable PC (8), electronic medical records (9) and bioelectricity measurement files (10). The bioelectricity measurement apparatus is characterized in that the electrodes (1) are mounted at to-be-measured bioelectricity parts of a human body; weak bioelectricity signals are amplified by the signal conditioning circuit (2), and amplified bioelectricity signals are transmitted to the data acquisition card (3); the apparatus driver (4), the panel program (5), the application program (6) and the virtual apparatus development platform (7) software are installed on the portable PC (8), and operation interface of the bioelectricity measurement apparatus for operating the whole apparatus is developed on the portable PC (8); meanwhile, bioelectricity measurement records are automatically generated and are converted into the medical records (9) and the bioelectricity measurement files (10) according to measurement results. The bioelectricity measurement apparatus implements synchronous measurement of various bioelectricities of the human body; on one apparatus, measurement of electroencephalography, electromyography, electrooculography (including retina electrography and nystagmus) and electrogastrography is synchronously achieved.

Description

technical field [0001] The invention relates to a medical measuring instrument suitable for general practitioners. Background technique [0002] The phenomenon of bioelectricity is the basic characteristic of life activities. Almost all life processes are accompanied by the generation of bioelectricity. Bioelectricity is an important information reflecting various physiological states of the human body. The research and records of various bioelectricity of the human body have become a reliable basis for mastering human body functions, clinical diagnosis and treatment. [0003] But in reality, all kinds of bioelectric measuring instruments have a single measurement function, such as electrocardiograph, electroencephalograph, myograph, oculograph (including retinal electricity and nystagmus), gastric electricity, etc., which cannot perform various functions of the human body. This kind of synchronous measurement of bioelectricity can only be used in hospitals. General practit...
