Description

Airflow distribution continuous driving medical atomizer and airflow distribution continuous driving method

Technical Field

The invention relates to the field of medicine, in particular to an airflow distribution continuous driving medical atomizer and an airflow distribution continuous driving method.

Background

Compared with the traditional means for treating respiratory diseases such as asthma by taking medicines, the medical atomizer atomizes the liquid medicine into tiny particles, and the medicines enter the respiratory tract and the lung for deposition in a respiratory inhalation mode, so that painless, rapid and effective treatment is achieved, and the device belongs to two types of medical devices. The medical atomizer has wide application range and is suitable for the following patients: respiratory disease patients are increased, especially children with poor autoimmunity are increased, for example, children always cough, the children take medicines inconveniently and feel pain by traditional medication or injection, and the medicines are absorbed slowly by muscles or blood, so that the children are decocted for a long time; the hospital is troublesome to visit, queue and register, the waiting time is long, and the environment of the hospital has the risk of cross infection; the medicine flowing through the whole body may have side effects, which are not good for the healthy growth of children. The disease condition is repeated, and the saline is hung by frequent injection; the medicine is troublesome to take at home, and the effect is slow; meanwhile, the medicine is three-way toxic, and is more likely to be dependent after long-term administration. A plurality of hospitals already develop atomization treatment means, and compared with the traditional medicine taking or injection treatment, the atomization treatment device has the advantages of no pain and quick response. The medical atomizer is mainly used for treating various upper and lower respiratory system diseases, such as common cold, fever, cough, asthma, sore throat, pharyngitis, rhinitis, bronchitis, pneumoconiosis and other diseases in trachea, bronchus, alveolus and thoracic cavity. There are three types of medical atomizers, and the mainstream types are compression type atomizers and ultrasonic atomizers. The gas compression type air compression atomizer forms high-speed airflow by utilizing compressed air through a fine pipe orifice, the generated negative pressure drives liquid medicine to be sprayed onto an obstruction together, and liquid drops splash to the periphery under high-speed impact to be changed into mist-shaped particles to be sprayed out from an air outlet pipe.

However, the conventional air compression atomizer of the gas compression type has certain defects in use, and the defects are collectively expressed as follows: firstly, the main machine part of the traditional gas compression type air compression atomizer can be recycled when in use, a long medical connecting pipe is externally connected when in use, compressed air is sent into the liquid medicine cup assembly, and atomized liquid medicine is sent into the nasal mask through a medicine outlet at the top of the liquid medicine cup assembly after atomization physical reaction, so that a disposable consumable material pipeline needing to be connected is long, resource waste is caused, meanwhile, the liquid medicine cup assembly is also a disposable consumable material, and the consumable material needs to be replaced after each use, so that great waste is caused; secondly, when the traditional gas compression type air compression atomizer is used, a patient or an assistant always holds the liquid medicine cup assembly by a hand of the patient, and the nose and mouth cover is covered on the nose and mouth part of the patient to carry out medicine suction operation, so that one hand of the patient needs to be continuously operated in the whole process, the operation is labor-consuming, and great defects exist; in addition, traditional gas compression formula air compression atomizer when using, to relying on the outside miniature air compressor who sets up to provide gas source power, during the use, when some special needs patients use, the speed of air current can not obtain reasonable control, in addition, receive the influence of external environment factor, traditional gas compression formula air compression atomizer can not implement accurate location and speed governing to the concentrated supply of air current, can not implement the concentrated continuous drive operation of dosing after the liquid medicine atomizing, cause the loss of part liquid medicine.

Therefore, the medical atomizer driven continuously by the airflow distribution and the continuous driving method of the airflow distribution are simple in structure, convenient to operate, high in working and running efficiency, stable in working state, capable of saving pipeline connection medical resources, relieving the pain of a patient in long-time handheld operation, reasonably distributing airflow, continuously and reasonably driving the distributed airflow, simple in method and easy to operate, and wide in market prospect.
