The hyfrecator does not require a dispersive return pad, referred-to in the electrosurgery field as a "ground pad," or "patient plate," because the hyfrecator can pass a very low-powered current between forceps tips via bipolar output, or pass an A.C. current between one pointed metal electrode probe and the patient, with the patient's self ...
The term "return electrode" is also technically incorrect since alternating electrical currents refer to alternating polarity, a circumstance that results in bidirectional flow across both electrodes in the circuit. Bipolar instruments generally are designed with two "active" electrodes, such as a forceps for sealing blood vessels.
A major branch is medical biostatistics, which is exclusively concerned with medicine and health. [66] Bipolar disorder – is a mental disorder that causes periods of depression and periods of abnormally elevated mood [67] [68] [69] Birth control – also known as contraception and fertility control, is a method or device used to prevent ...
The DSM-5 has established a diagnosis—disruptive mood dysregulation disorder—that covers children with long-term, persistent irritability that had at times been misdiagnosed as having bipolar disorder, [126] distinct from irritability in bipolar disorder that is restricted to discrete mood episodes.
Bipolar, where both electrodes are mounted on same pen-like device and electric current passes only through the tissue being treated. Advantage of bipolar electrosurgery is that it prevents the flow of current through other tissues of the body and focuses only on the tissue in contact.
Definition page from Amy Pope's 'A medical dictionary for nurses' (1914) A medical dictionary is a lexicon for words used in medicine. The four major medical dictionaries in the United States are Mosby's Dictionary of Medicine, Nursing & Health Professions, Stedman's, Taber's, and Dorland's. Other significant medical dictionaries are ...
Second, medical roots generally go together according to language, i.e., Greek prefixes occur with Greek suffixes and Latin prefixes with Latin suffixes. Although international scientific vocabulary is not stringent about segregating combining forms of different languages, it is advisable when coining new words not to mix different lingual roots.
Bipolar plate Bipolar plate, conductive plate in a fuel-cell stack that acts as an anode for one cell and a cathode for the adjacent cell. The plate may be made of metal or a conductive polymer (which may be a carbon-filled composite). The plate usually incorporates flow channels for the fluid feeds and may also contain conduits for heat transfer.
