Embodiment Construction
[0023] Below in conjunction with accompanying drawing, specific embodiment of the present invention is described in further detail:
[0024] Such as figure 1 As shown, a wound atomization drug delivery and intermittent negative pressure sealing drainage device of the present invention includes a wrapping material 3, a drainage tube 4, a negative pressure source 5, an ultrasonic nebulizer 1, an atomized gas introduction tube 2 and a micro-processing Controller control unit 6. The wrapping material 3 is generally a medical foam material. When in use, cover the wound with the wrapping material 3 and then seal it with a semi-permeable adhesive film to seal the wound. Drainage tube 4 is two, and its one end has side hole, and this end inserts wrapping material 3; There are also two atomized gas introduction pipes 2, one end of the two atomized gas introduction pipes 2 is connected to the ultrasonic atomizer 1 through a tee, etc., and the other end has a side hole and is inserted ...
