Non-invasive hemodynamic interventional therapy: Treatment principle; Non-invasive hemodynamic interventional therapy fully utilizes the non-invasive nature of ultrasound interventional disciplines and the accuracy of targeted interventions, targeting the leg lesion site, according to the hemodynamic principles of a single interventional treatment, while selecting the characteristic vascular nutrient drugs, with the leg vessels to restore the function of the venous valve, restore the blood flow in the deep veins, thereby improving the blood circulation of the surface layer To achieve the effect of complete cure. 6 advantages: 1, non-invasive technology without pain: no incision, no surgery, no pain, say goodbye to the era of the scalpel, breaking the traditional high ligation, stripping the pain. 2.Natural beauty without scars: recovery as before, no scars, one week after treatment, varicose parts can be restored to the state of smooth skin, and will not leave any scars. 3.One-time treatment without recurrence: So far, more than 10,000 cases have been relieved of pain, and there is no case of recurrence. 4.With the treatment, no hospitalization: treatment is rapid, with the do, no hospitalization, can leave after doing. 5, eliminate complications: natural treatment of Chinese medicine, non-surgical, no incision, non-invasive treatment recovery faster, after treatment will not have any complications. 6, wide range of treatment: completely regardless of age, regardless of gender, regardless of industry, regardless of the urgency of the disease, the length of the disease, can be treated. Lower extremity phlebitis – care measures: 1, the occurrence of lower extremity phlebitis, such as general indwelling needle should be removed, change the puncture site, inflammation site can be given hot compress, symptoms should be improved within 3 days, if there is no sign of improvement should notify the physician to assess whether bacterial infection. 2.If lower limb phlebitis occurs in PICC (peripheral venous puncture into central catheter), hot compress can be applied first, if it is mechanical or chemical lower limb phlebitis, the symptoms should be relieved, if the symptoms persist and there is no sign of improvement, then it should be removed. 3.If wet and hot compresses are applied, hot and wet towels can be used to apply hot compresses for 20 minutes each time, 4 times a day. 4.If bacterial lower limb phlebitis is suspected, the doctor should be notified to perform catheter needle and blood culture, and blood culture should be taken from other veins and one from each catheter for blood culture as a basis for diagnosis. 5.If there is pus, the purulent fluid should be cultured, and sterile cotton swabs need to be used for this purpose; before taking the sample, avoid disinfecting the skin to avoid affecting the culture of bacteria. 6.Elevate the affected limb to promote blood circulation and repair. 7.If chemical reaction is suspected, it needs to be recorded. It should be recorded according to the recording method developed by the Intravenous Infusion Association in order to achieve consistency in the judgment standard of nursing staff. 8.Avoid puncturing inflamed vessels again. Inflamed vessels should not be used until symptoms have fully recovered and elasticity has been restored.
