Wound treatment device utilizing high voltage to generate plasma

Abstract

The invention discloses a wound treatment device utilizing high voltage to generate plasma. A cut-through cavity is formed axially in an insulating shell, a boss is arranged in the cavity of the insulating shell, a cone-shaped cavity is arranged on the side of the boss close to a spout of the insulating shell, vent holes are formed at boss shoulder portion of the boss, an insulating fixing plate is arranged at the boss of the cavity of the insulating shell, a rear back cover is fixed at the end of the insulating shell far away from the spout, an outer cover is fixed on the rear back cover, and seven rodlike metal electrodes are arranged axially in the cavity of the insulating shell; storage batteries are connected with high voltage power, an air pump and a cooling fan in a main engine respectively, a miliampere ammeter is connected with the high voltage power, and a gas flowmeter is connected with the air pump. With the wound treatment device, wound infection probability particularly during large-size wound operations is decreased, both antibiotic usage amount and side effect of patients are reduced, and wound union speed is fastened; dielectric barrier discharge and decrease of discharge voltage are not needed, extra water container is not needed either, and the structure is simple and reliable.

Description

technical field [0001] The invention relates to a wound treatment device, in particular to a wound treatment device which utilizes high voltage to generate plasma. Background technique [0002] In life, it is inevitable that there will be accidental injuries, such as knife wounds, abrasions and so on. For teenagers and elderly people with relatively low resistance, if the wound is not treated in time, especially when the wound is large and deep, it will be difficult to deal with it at the first time, and infection is likely to occur. Foreign studies have shown that under a certain dose of low-temperature and atmospheric-pressure plasma (<1Jcm -2 ) can kill bacteria without harming animal and human tissue cells, and has certain wound recovery and blood coagulation effects. In this way, plasma can be well applied in large area trauma surgery, severe trauma and other situations. [0003] Many documents have proved that hydroxide ions and hydronium ions in plasma are the m...
