Nasal cavity sustained release drug dosing device

Abstract

The invention belongs to the field of nasal cavity drug dosing and therapeutic equipment, and particularly relates to a nasal cavity sustained release drug dosing device comprising an eyeglass frame,a spring clip, a liquid storage bag, a capillary tube, a curved support frame, a clip piece and a contact. The spring clip is movably arranged under the eyeglass frame, and the spring clip is n-shaped. The lower end of the spring clip is provided with the curved support frame, and the curved support frame is tilted upward. The connection between the spring clip and the curved support frame is provided with the clip piece, and the clip piece is tilted upward. The upper end of the curved support frame is provided with the liquid storage bag, and the contact is disposed under the liquid storage bag through the capillary tube and disposed at the top end of the clip piece. The dosing device is attractive in appearance, can preheat a drug during dosing to the nasal cavity, and allows the drug tobe slowly released into the nasal cavity continuously, and the therapeutic effect is achieved through the nasal cavity, so that the drug is more acceptable to a patient, and the therapeutic effect isgood.

Description

technical field [0001] The invention belongs to the field of nasal cavity drug delivery treatment equipment, in particular to a nasal cavity sustained release drug delivery device. Background technique [0002] The nose is the initial part of the respiratory passage and also an olfactory organ. It consists of three parts: the external nose, nasal cavity and paranasal sinuses. It is composed of nasal bones, nasal cartilage, nasal muscles and covering skin. The nasal cavity is divided into left and right chambers by the nasal septum. The nostrils communicate with the outside world at the front, and the nasopharynx at the rear. The inner surface of the nasal cavity is the mucous membrane with a surface area of ​​up to 150 cm 2 , and shows that there are a large number of microvilli, and the lower layer is rich in capillaries and lymphatic capillaries, which is an ideal drug delivery route. The nasal mucosa drug delivery preparation has the following advantages: [0003] 1. Hi...

AI Technical Summary

Problems solved by technology

When the nose is sick, it is often uncomfortable and difficult to treat, because it takes a long time for the medicine to reach the nose. The existing nasal spray treatment equipment can only provide high-concentration medicine liquid in an instant, but there is no one that can continuously provide nasal medicine. A device that provides drugs, so there is a need for a device that can sustain sustained drug delivery through the nasal cavity for a long time to reduce people's pain
