Example Embodiment
[0015] Example one
[0016] The invention provides a phospholipid microbubble suspension, the particle size of the microbubbles is 2.4±0.5um. The gas contained in the microbubbles is perfluoropropane; the solvent of the microbubble suspension is saline; and the antibacterial agent is vancomycin.
[0017] The method for inhibiting and removing the root canal biofilm is as follows:
[0018] 1) Inject normal saline (control group) and phospholipid microbubble suspension into the root canal of tooth 1 infected by biofilm, the concentration of the microbubble is 1*10 7 / ml, 5*10 7 / ml, 1*10 8 / ml, using a syringe to repeatedly blow 20 times to ensure that the phospholipid microbubbles are evenly distributed in the root canal.
[0019] 2) Put the root canal ultrasonic therapy instrument 3 into the root canal
[0020] 3) Apply ultrasonic treatment, set the ultrasonic frequency to 42kHz and the ultrasonic time to 1min.
[0021] 4) Then use normal saline to rinse the root canal three times to wa...
Example Embodiment
[0023] Example two
[0024] The invention provides a surface active agent microbubble suspension, the particle size of the microbubbles is 1.8±0.4um. The gas contained in the microbubbles is air. The solvent of the microbubble suspension is physiological saline; the antibacterial agent is hydrogen peroxide with a mass fraction of 3%.
[0025] The methods for inhibiting and removing the biofilm on the surface of the medical device are as follows:
[0026] 1) Place the medical device (surgical forceps) in the bracket, and then inject the surfactant microbubble suspension into the bracket to make the microbubble suspension completely immerse the medical device, and finally ensure that the final concentration of the microbubble is 1* 10 6 / ml, then stir for 2min to ensure full contact between the microbubbles and the medical device.
[0027] 2) Put the brackets in the ultrasonic cleaner for 10 minutes.
[0028] 3) Then use distilled water to rinse the medical equipment 3 times, and rinse...
