The invention relates to the field of medical instrument accessories, in particular to an air-liquid pipeline
assembly of an early-stage debridement flusher. The
assembly comprises a protective sleeve, a liquid obtaining needle, a power pneumatic interface, a special
bottle cap and a handheld
machine interface, and the protection sleeve and the liquid obtaining needle are hermetically hinged through a ring belt groove and a protruding clamping ring, so that the
assembly is not contaminated by
bacteria in use. The liquid obtaining needle is provided with an air inlet needle and a liquid outletneedle to complete air pressure and liquid power conversion; a liquid obtaining needle protective plate protects the local clean and aseptic environment of the special
bottle cap. A liquid path interface is connected with the handheld
machine interface through a blue liquid pipeline, a red liquid pipeline and a colorless liquid pipeline; an air path interface is connected with pneumatic power through the power pneumatic interface to quickly
cut off the dynamic air pressure and the local
air tightness; a sealing rubber pad of the special
bottle cap is provided with a preset puncture point so that the liquid obtaining needle can conveniently puncture the sealing rubber pad and balanced wrapping force can be generated, and then an acceptable airtight state is formed; the air-liquid pipeline assembly can be used for conveniently replacing an associated assembly. Therefore, an operator can conveniently and accurately complete a debridement flushing procedure.
