A method for using a disposable local anesthesia analgesic system,
step one, filling and exhausting: filling liquid is injected from the end part of the infusion strip 102, and flows through the infusion strip 102, the bacterial filter 104, the shunt inner tube 202, the liquid medicine through groove 402, the permeation inner tube 604, the permeation connecting tube 606 and the permeation side hole 603 in sequence, and the infusion strip 102, the bacterial filter 104, the shunt inner tube 202, the liquid medicine through groove 402, the permeation inner tube 604, the permeation connecting tube 606 and the permeation side hole 603 form a medicine delivery pipeline, so that air in the medicine delivery pipeline is emptied;
step two, dispensing: medical staff prepares analgesic liquid medicine inside the elastic silicon capsule 101, and connects and fixes the elastic silicon capsule 101 and the infusion strip 102, so that the analgesic liquid medicine can be sent into the medicine delivery pipeline;
step three, puncture fixation: inserting the T-shaped avulsion sheath 602 into a wound through the skin at the edge of the wound, pulling the permeation catheter 601 to enable the permeation catheter 601 to be arranged at a proper position of the wound, then avulsing the T-shaped avulsion sheath 602, carrying out external fixation on the permeation catheter 601, and suturing the wound by medical staff after the fixation is finished, wherein liquid medicine seeps out from the permeation side hole 603 buried in the wound at the moment, so that continuous infiltration and analgesia can be carried out on the wound;
step four, air inflation isolation: the inflatable bag 302 is utilized to inject gas into the air inlet pipe 203, the gas sequentially flows through the air inlet pipe 203, the annular interlayer space between the split outer pipe 201 and the split inner pipe 202, the gas distribution groove holes 403 and the inflatable gas grooves, the air inlet pipe 203, the annular interlayer space between the split outer pipe 201 and the split inner pipe 202, the gas distribution groove holes 403 and the inflatable gas grooves form a gas circuit pipeline, so that the surface of the permeable pipe 601 close to the inflatable gas groove filled with the gas is inflated fully, the surface of the permeable pipe 601 close to the inflatable gas groove not filled with the gas is inflated, the gas in the inflatable gas groove is contracted into the inflatable gas groove under the action of the inflation tension of the inflatable parts at the two sides, the gas in the inflatable gas groove is exhausted to the outside from the gas distribution groove holes 403, the inflatable gas groove isolates analgesic liquid in the permeable inner pipe 604 from a wound, the heat conduction efficiency of the analgesic liquid at low temperature in the wound direction can be reduced, the body heat sensitivity is improved, and the comfort of a patient is effectively improved;
