According to the Wound healing and bone regeneration instrument of the present invention, when the Wound healing and bone regeneration instrument treat wound, by drainage tube 600
Vessel clamp removed from drainage tube 600, or open vessel clamp relaxation drainage tube 600 so that negative pressure source 500 passes through drainage tube
600 and comb 601 to wound carry out suction pressure, drainage tube 600 and comb 601 drain wound fluid from wound
Come, suction pressure operation through after a period of time, it is necessary to carry out stop suction pressure operation when, close negative pressure source 500 after, can be by vessel clamp
It is clipped on drainage tube 600, grip drain tube 600, prevents outside air from being entered by drainage tube on wound surface, cause wound
Infection；When carrying out suction pressure to wound again, aforesaid operations are repeated.
According to a kind of embodiment of Wound healing and bone regeneration instrument of the present invention, medical film 100 includes being used to seal the poly- of wound
Urethane film layer, the acrylic pressure sensitive glue-line being arranged in polyurethane film layer, the lining being connected with polyurethane film layer edge,
And the adherent layer being connected with acrylic pressure sensitive glue-line.
According to the Wound healing and bone regeneration instrument of the present invention, polyurethane film：It has unique molecular structure, conforms to hydrophilic group
It penetrating can lead wet, there is fungi-proofing, dust-proof, waterproof and moisture-inhibiting；
Acrylate pressure sensitive adhesive：It is the sub- quick glue of medical grade, non-toxic, non-stimulated, low sensitization, have it is good hold viscosity,
Tack and penetrability, while peel strength is low, mitigates the pain caused by peeling off to patient；
Lining：It can ensure that film is unfolded smooth, does not play fold, and visual wound site, and to be accurately pasted on the surface of a wound, it is closed
The structure of reason and when can ensure that transparent pad pasting removes adherent layer with the adhesive force of polyurethane film polyurethane film not from lining
Come off, lining can be removed easily without polyurethane film is taken up from skin after sticking skin；
Adherent layer：Material is release liners.
Finally it should be noted that：Various embodiments above is merely illustrative of the technical solution of the present invention, rather than its limitations；To the greatest extent
Invention is described in detail with reference to foregoing embodiments for pipe, it will be understood by those within the art that：It is still
Technical scheme described in foregoing embodiments can be modified, either which part or all technical characteristic are carried out
Equivalent substitution；And these modifications or replacement, the essence of appropriate technical solution is departed from various embodiments of the present invention technical side
The scope of case.
