Experimental device for experiments of intervention on bacterial biofilm through high-intensity focused ultrasound

The utility model discloses an experimental device for experiments of intervention on a bacterial biofilm (BF) through high-intensity focused ultrasound (HIFU), which comprises a container (1) containing degassing water, a fixing device (3) is immersed in the degassing water, an experimental piece (2) is fixed on the fixing device (3), and a HIFU treating head (5) is arranged at a position of the outside of the container (1) corresponding to the experimental piece (2). The experimental device is simple in structure and convenient to operate, has high success ratio in production and excellent effect in fixing of the experimental piece, and successfully fixes the BF in a focused area of HIFU treatment, thereby facilitating the experiments.
