Description

Device for treating lymphatic vessel deformity by objectively and quantitatively injecting medicine dose

Technical Field

The utility model relates to a medical treatment injection device field especially relates to a device that is used for objective ration injection medicine dose to treat lymphatic vessel deformity.

Background

Lymphangioma (LM), which has been known as "lymphangioma," is a common congenital vascular malformation disease. LM can be classified into three types, i.e., macrocyst type, microcapsule type and mixed type, according to the size of the lymphatic tumor cavity. The macrocapsular LM consists of 1 or more tumor cavities with a volume of 2cm or more (known as cyst-type or cystic edema), while the microcapsule LM consists of more tumor cavities with a volume of 2cm or less (known as capillary and sponge), both of which are known as mixed LM. The incidence rate of LM is 1/4000-1/2000, and no sex and ethnic difference is found. The disease usually occurs before the age of 2 years, and about 50% of patients are born with the disease. LM can occur in any body part with lymphatic ductal network, with about 75% of lesions occurring in the head, neck, and next to the armpits, mediastinum, and limbs. LM is considered a benign lesion of the lymphatic system, growing slowly with little natural regression. But often suddenly increases after suffering trauma, infection, and the occurrence of intracapsular hemorrhage or improper treatment. If LM grows in a special position, it may cause disfigurement, deformity, and stress of important organs to cause dysfunction, resulting in long-term sequelae.

At present, LM has various treatment methods, and the interventional injection treatment is used as a novel treatment means and has been widely applied to clinic due to the characteristics of local administration, good effect, little side effect and the like.
