A handheld air plasma spray is designed. Plasma is generated by a magnetized arc torch running at 60 Hz and is in non-equilibrium state the plasma effluent is low temperature (touchable) and yet contains high energy electrons (> 5 eV) capable to dissociate oxygen molecules to atomic oxygen. The emission spectroscopy of the torch indicates that the plasma effluent carries abundant atomic oxygen, which can effectively kill all kind microbes. Moreover, the experimental results show that this low temperature air plasma torch can rapidly clot blood. This invention is for blood coagulation and general sterilization applications.設計一種手提式空氣電漿產生及噴射的裝置。用60Hz運轉的磁化電弧火炬產生的電漿狀態並不平衡。電漿流體溫度雖低(可碰觸)仍帶有高能量電子(>5eV)可分離氧分子成為氧原子。火炬的發射光譜顯示電漿流體帶有大量活性氧原子,能有效殺死所有的微生物。另外,實驗結果顯示低溫空氣電漿火炬可以快速凝結血液。本發明是用於傷口止血及一般消毒應用。
