ELECTROMECHANICAL APPARATUS DEVICE FOR MUSCULAR SPASMOLYSIS REQUIRED IN EXTRACTION OF ACUPUNCTURE NEEDLE STUCK IN TISSUES Russian patent published in 2012 - IPC A61H39/00 A61N1/32 A61N1/18 

FIELD: medicine.

SUBSTANCE: invention refers to medical equipment, namely to apparatuses for muscular spasmiolysis required in extraction of an acupuncture needle stuck in tissues. The apparatus comprises two electrodes, one of which is connected to patient's skin and the other one is connected to a handle of the stuck needle. Besides, it comprises a piezoelement and a drive, a voltage limiter with its input connected to a first terminal of the piezoelement and with its output connected to an anode of a rectifier diode with its cathode connected to a first terminal of a storage capacitor, an input of an electronic switchboard, a cathode of a protective diode and an input of an actuator. An output of the actuator is connected to a control input of the electronic switchboard with its output connected to an input of a pulse shaper. An output of the pulse shaper is connected to the first electrode. The second electrode is connected to an anode of the protective diode, a second terminal of the storage capacitor and a second terminal of the piezoelement.

EFFECT: use of the invention shall enable higher speed and effectiveness of extraction of the acupuncture needle stuck in tissues.
