In-depth and precise drug delivery device and drug delivery method based on respiratory medicine

Abstract

The invention discloses an in-depth and precise drug delivery device and drug delivery method based on respiratory medicine, which includes inserting a vertical tube, the lower end of which is inserted into a non-inflatable cuff, and the upper end of which is inserted into the vertical tube. The upper end is connected with an adjustment cylinder, the adjustment cylinder and the insertion vertical cylinder are provided with an insertion outer tube, the outer wall of the insertion outer tube is provided with external threads, the inner wall of the adjustment cylinder is provided with internal threads, and the inner coaxial sleeve of the insertion outer tube is provided with an insertion inner The tube is inserted into the inner tube to be provided with a clapboard, and a drug storage bin is formed under the clapboard, a nozzle is installed on the clapboard, the lower end of the nozzle is connected with a jet tube, and the lower end of the inserted outer tube is connected with a joint, and a nozzle is installed on the joint. The drug delivery device of the present invention can directly reach the patient's site in a relatively gentle way for in-depth and precise drug delivery, and atomize the drug solution into a drug mist through the ventilation method, which can evenly deliver drugs to the patient's site in the respiratory department. The work difficulty of the medical staff when in-depth administration of drugs is alleviated, and at the same time, the overall structure is simple, easy to operate, and strong in practicability.

Description

technical field [0001] The invention relates to the field of respiratory examination, in particular to an in-depth and precise drug delivery device and drug delivery method based on the respiratory department. Background technique [0002] Usually, when people take medicines in dosage forms such as granules, powders, and dry suspensions, they need to add water to brew them before taking them, which is more time-consuming. At present, the common drug delivery devices are mainly medical atomized tablets, which are mainly used to treat various upper and lower respiratory diseases, such as cold, fever, cough, asthma, sore throat, pharyngitis, rhinitis, bronchitis, pneumoconiosis and other trachea, bronchi, Diseases occurring in the alveoli and chest cavity. Nebulization inhalation therapy is an important and effective treatment method in the treatment of respiratory diseases. The nebulizer inhaler is used to atomize the liquid medicine into tiny particles, and the medicine ente...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is that the existing drug delivery device is often unable to in-depth drug delivery, usually in the oral cavity, so the location of drug delivery is not accurate, and the drug cannot fully reach the patient's site, which is likely to cause drug waste and loss. The purpose of reducing drug efficacy is to provide an in-depth and precise drug delivery device and drug delivery method based on respiratory medicine, which can directly reach the patient for in-depth and precise drug delivery in a relatively gentle way, and atomize the drug solution through ventilation. The drug mist can evenly administer the drug to the patient's part in the respiratory department, which reduces the difficulty of the medical staff's work when the drug is administered deeply. At the same time, the overall structure is simple, easy to operate, and strong in practicability
