The invention discloses an aseptic infusion port auxiliary implantation device for intravenous infusion, which comprises a puncture sheath for guiding installation of a sterile port catheter, whereinthe puncture sheath mainly comprises a needle sheath, the front end of the needle sheath has a pointed structure, a needle cavity coaxially arranged with the needle sheath, and the needle cavity penetrates the needle sheath; The needle sheath head is sleeved at the posterior port of the needle sheath. In use of the invention, a fast dissolving adhesive portion is sent into the body together with the needle sheath, and the dissolving adhesive portion is sent into the body together with the needle sheath at a time of 5 minutes. 7 minute, that rapidly dissolving adhesive part gradually disintegrate, the catheter can then be inserted, And after it disintegrates, the left half sheath and the right half sheath can be separated quickly, Therefore, the invention can effectively separate and take out the needle sheath, thus greatly reducing the difficulty of taking out the needle sheath, avoiding the pulling of the catheter, so that the success rate of taking out the needle sheath is effectively improved, and meanwhile, the bacterial and viral infections occurring in the puncture process can be reduced by utilizing the specific antigen preparation with immunity.
Description
technical field [0001] The invention relates to the medical field, in particular to a sterile infusion port auxiliary implantation device for intravenous infusion. Background technique [0002] The implanted venous infusion port (Port), also known as the implanted central venous catheter system, referred to as the infusion port, is a closed venous infusion system that can be completely implanted in the body. Consists of a radiolucent catheter system. The puncture septum has the function of automatically "repairing" puncture damage, allowing 2,000 punctures with a 22G non-injury needle and 1,000 punctures with a 19G non-injury needle without leakage. It can be used for all intravenous treatments such as long-term high-concentration infusion of chemotherapy drugs, complete parenteral nutrition, blood products and collection of blood samples. The infusion port has fewer operation steps and less maintenance, which increases the freedom of movement of the patient and improves t...
