Vestibular administration device for nasal cavity

Abstract

The invention discloses a vestibular administration device for a nasal cavity, which comprises an air bag and a catheter communicated with the air bag; the catheter is used for filling gas or liquid into the air bag; and an administration surface is arranged on the air bag. Compared with the conventional atomizing administration mode or cotton ball administration mode, the vestibular administration device has the advantages that: 1, the administration time is long, and the administration dose is accurate; 2, the administration device is prevented from being fallen off, is convenient to operate and does not influence aeration; 3, the application range is wide in clinical medical treatment; and 4, the vestibular administration device has a structure and low manufacturing cost, and is convenient to popularize and use.

Description

technical field [0001] The invention relates to a medical device, in particular to a nasal cavity vestibular drug delivery device. Background technique [0002] Clinically commonly used methods of administration include oral administration, injection administration, skin patching, rectal administration, intranasal administration, and the like.

Problems solved by technology

In these administration methods, the residence time of the drug on the mucous membrane is short, and it is easy to lose to the throat, resulting in poor efficacy and inaccurate dosage of the drug, which affects the absorption of the drug by the nasal mucosa and affects the effect of the drug, especially analgesics or insulin. The administration method of cotton ball, the dosage is inaccurate, the mucous membrane can only absorb the drug on the surface of the cotton ball, and the drug that penetrates into the center of the cotton ball is difficult to absorb, and it will also be affected by nasal secretions
