Disposable nasal wash delivery device

Abstract

The invention provides a disposable nasal cleaning drug delivery device, which comprises a conical body, which is hollow inside and has an open top end, and at least one notch guiding groove is provided on the lower end part of the side wall; At the opening, the other end protrudes from the bottom end of the conical body and is provided with a syringe interface; the spray administration conduit, one end is installed at the center of the top opening of the conical body, and the other end protrudes from the bottom end of the conical body and is provided with a spray Bootstrap interface. In the rescue scene such as disaster, war-wound first aid, etc., the device of the invention can safely realize the continuous action of nasal cavity cleaning and nasal administration. Sedative drugs can effectively avoid the impact of foreign bodies such as dust on the surface of the nasal mucosa on the adhesion and absorption of drugs. The drug delivery effect is more reliable, and complex and dangerous steps such as disinfection and venous blood vessels are not required. It is more practical and feasible in out-of-hospital rescue places.

Description

technical field [0001] The invention belongs to the technical field of nasal emergency medical and nursing equipment, and in particular relates to a disposable nasal cleaning and drug delivery device for first aid and first aid treatment of war wounds. Background technique [0002] The pain, tension and anxiety on the scene of the wounded cannot be dealt with immediately after the injury, and the resulting problems such as post-treatment traumatic stress syndrome are becoming more and more serious. It is a difficult problem faced by the current emergency. At present, with the progress of medical first aid and war trauma treatment technology, the success rate of treatment has been continuously improved. At the same time, several types of safe and non-addictive analgesic and sedative drugs have come out and entered clinical practice and achieved satisfactory results. However, these drugs need to be injected intravenously under the medical sterile conditions of the hospital to...

Problems solved by technology

[0006] 1. At present, all products are designed by integrating the medicine storage bottle and the spray head, which can be used for one-time use. One bottle can only be used repeatedly by one patient, but each wounded person only needs to use it once in the first aid scene. The use of optimized design will cause high cost and waste or cannot meet the on-site usage

[0007] 2. At present, most products spray high-concentration medicinal liquid on the surface of the nasal mucosa in the form of spray, and then penetrate into the nervous system and capillaries to play a role. However, these products are aimed at patients whose nasal cavity is usually clean

The surface of the nasal mucosa of the wounded in disasters and battlefield detonations must have a lot of dust and other substances, which will greatly affect the adhesion and penetration of the drug into the internal environment of the body to play a role, the effect will also be weakened, and the onset time of the drug will also be delayed. Difficulties in on-site treatment
