美军牙医研究所进行了一系列研究,将水力冲洗装置分脉冲式和非脉冲式二种。冲洗力最大为每分钟喷出水2400ml,分1～8个水柱,其喷射力约200 PSI(磅/吋~2),此压力可以调节大小,用此装置进行以下实验:一、各种不同冲洗力对口腔和舌粘膜的作用:用60只鼠和4只狗作实验,不同冲洗力冲洗30秒钟,证明50-70PSI冲洗力可以安全地用于人的粘膜组织。二、此脉冲式和非脉冲式冲洗对组织的作用:同样冲洗力对牙龈(致密组织)进行冲洗反应相似;对疏松粘膜冲洗时非脉冲
A series of studies were conducted by the U.S. Army Dental Institute to divide the hydraulic flushing devices into two types, pulsed and non-pulsed. The maximum flushing force is 2400ml of water per minute, divided into 1 to 8 water columns, the injection force of about 200 PSI (pounds / inch ~ 2), the pressure can be adjusted in size, with the device for the following experiments: A variety of different Flushing Force on Oral and Tongue Mucosa: Experiments with 60 mice and 4 dogs, rinsing with different rinsing forces for 30 seconds, demonstrate that 50-70 PSI rinsing force can be safely applied to human mucosal tissue. Second, the pulsed and non-pulsed flushing on the role of the organization: the same flushing force on the gums (dense tissue) flushing response similar to loose mucosal flushing non-pulse
