Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to nasal administration equipment for ear, nose, throat, head and neck surgery.
Background
Nasal administration refers to a method of administration by nasal administration, which is absorbed through the nasal mucosa to exert a local or systemic therapeutic or prophylactic effect. The total area of the nasal cavity is about 150 square millimeters, the surface of the nasal cavity is covered by mucous membrane, and the thickness of the nasal cavity is 2-4 millimeters. The nasal mucosa is rich in blood vessels and lymphatic vessels, and has a unit blood flow larger than that of muscles, brain and liver. The polypeptide drug directly enters the circulatory system after penetrating through the nasal mucosa, so that the first pass effect of the liver is avoided. There are 4 paranasal sinuses near the nose, and the mucous membrane of the paranasal sinuses is continuous with the nasal mucous membrane, so the medicine can be easily absorbed and diffused. The nasal cavity is a part of the skull and has many small holes, the endothelium of the nasal cavity is like a sieve-like plate, the nerve bundles pass through the small holes and are filled with cerebrospinal fluid, therefore, part of the medicine can enter the cerebrospinal fluid after dropping into the nasal cavity, and the way of delivering the medicine into the brain can be realized.
Administration to the nasal mucosa allows for rapid and efficient delivery of the drug to the blood. However, the nasal delivery devices currently on the market are mostly adapted for liquid drug formulations, which are less effective than powder drugs, since liquid formulations tend to be more unstable and require certain storage requirements. The dry powder is directly sprayed into nasal cavity, so that the absorption effect is best and the storage is easier.
