A radio frequency ablation device () comprising a balloon blocking catheter. The radio frequency ablation device () comprises a double or multi-lumen balloon blocking catheter () and a radio frequency ablation catheter (). a stent () is arranged at the far end of the radio frequency ablation catheter (). Two or more electrodes () are arranged on the stent (), and are connected to a radio frequency generator respectively by means of the corresponding guide wires arranged in the radio frequency ablation catheter (). When the radio frequency ablation device () is used for ablating blood vessel peripheral nerves, inflating a blocking balloon () arranged at the far end of the guide catheter () to block local blood flow in a blood vessel. The invention has ideal nerve ablation effect.

The present invention discloses a flying capacitor converter, a short circuit current suppression circuit for the same and an energy storage system. The flying capacitor converter comprises a controller, and has a high voltage side connected to a first power source and a low voltage side connected to a second power source. The short circuit current suppression circuit comprises: at least one current detection unit connected to the low voltage side and/or the high voltage side of the flying capacitor converter; and at least one switch set connected in series to the high voltage side and/or the low voltage side of the flying capacitor converter, wherein the controller controls the switch set to cut off a connection between the flying capacitor converter and the first power source and/or between the flying capacitor converter and the second power source, when the current detection unit detects a short circuit.

A comfortable and viable and removable device of channel-type tongue position correction for anti-snoring. The device is made of wire or band material, including a fixer, an upper and nether force-components which are connected with the fixer. The device is mostly applied on upper jaw. The force end of the upper force-component is designed to be suitable to the soft palate palatine velum, and acts to raise up the soft palate palatine velum and uvula upward/upward and backward suitably. The force end of the nether force-component is designed to be suitable to the normal configuration of the corpora linguae (anterior tongue), and acts on the portion in front of the sensitive position of the hind half of the corpora linguae (anterior tongue) to press the big tongue downward/downward and forward. Thus, depending on the co-action of the upper and nether force-components, the blocked respiratory tract could be expanded to prevent snore and remit sleep apnoea syndrome.
