Description

Hemostatic sleeve for endoscope

Technical Field

The utility model relates to a medical device, in particular to a medical scope hemostasis sleeve pipe.

Background

With the development of endoscopic treatment, more and more hospitals developed esophageal varices sclerosing treatment aiming at treating and preventing esophageal venous bleeding by occluding esophageal varices veins through sclerosing agents. The specific method comprises the following steps: the gastroscope is inserted into the hemostatic sleeve of endoscope, and the sclerosing agent is injected into varicose vein through special injection needle under the direct vision of gastroscope. The sclerosing agent rapidly coagulates in the blood vessel and stimulates the blood vessel to produce inflammation, and finally hardens, thereby achieving the purpose of occluding the blood vessel. Under normal conditions, the sclerosing agent injected into the vein flows along with blood, so that the concentration of the medicine at the treatment part is rapidly reduced, the treatment effect is influenced, if the defects are solved by increasing the dosage of the medicine, the side effect of the medicine on the human body is correspondingly increased, and the effect is not ideal; in addition, the needle eye after intravenous injection may have problems of bleeding and outflow of the drug.
