Способ оценки раздражающего действия внутрисосудистых катетеров in vivo

Preclinical evaluation irritant intravascular catheters designed for installation in the human saphenous veins, invited to conduct IN VIVO piglets with a thermal imager. To measure the temperature of the skin in the selected area pigs, injected into a selected vein catheter isothermal and every 30 minutes in the horizontal bent limb proximal joint 90 ° for a period of 30 minutes, and then straightened to its original state. The temperature and the infrared spectrum recorded after one hour and just prior to the installation by removing the catheter. The method improves safety, accuracy and speed estimation irritating catheter through the emergency information on skin irritation, subcutaneous fat and venous endothelial wall in the moving limb.
