Description

Technical Field

[0001] The utility model belongs to the technical field of medical drug delivery auxiliary equipment, and in particular relates to a respiratory drug delivery device. Background Art

[0002] The respiratory tract is usually divided into the upper respiratory tract and the lower respiratory tract. The upper respiratory tract usually includes the nasal cavity, oral cavity, pharynx, and laryngeal organs, which usually play a role in maintaining ventilation, and can also play a role in warming the air and filtering harmful substances in the air. At the same time, the upper respiratory tract is also the most prone to disease. The lower respiratory tract usually includes the trachea, bronchi, and lungs, which can replace the air inhaled by the upper respiratory tract and then eliminate carbon dioxide. The entire respiratory tract is covered with mucous membranes and capillaries. The mucous membranes are also divided into cilia, which can protect the respiratory organs and the human body. The main cause of respiratory tract infection is the effect of cold, especially when life management is not appropriate, it is more likely to occur, such as sleeping outdoors on a cold night, lying in a cold place for a long time, being attacked by a thief wind, being exposed to rain after sweating, or being stimulated by cold water when wading across a river, living in a cold and humid environment for a long time, etc., can reduce the resistance of the upper respiratory tract mucosa and promote the occurrence of this disease.

[0003] The otolaryngology is the opening of the human head and face to the outside world. It is susceptible to adverse stimulation from environmental, physical, chemical, and biological factors, resulting in structural and functional disorders, among which various inflammatory lesions are the most common. Various treatment methods are widely used, and drug treatment is a very important component. After respiratory tract infection, discomfort will occur in the throat and nose, the throat will hurt, and the pharynx will be red and swollen. The usual treatment method is to take orally or inject anti-inflammatory drugs and other drugs. The drugs need to enter the lesions after the human blood circulation, and the efficiency of removing the lesions is slow and the effect is not good. Or oral drugs are bitter, which increases the pain of patients, and the lesions cannot be treated directly. There is no targeting and the treatment efficiency is low. Most of the existing drug delivery devices are sprays. After the spray is sprayed, the drugs will disperse and still cannot reach the lesions directly. If the drugs can be delivered directly to the lesions, the drugs will take effect quickly, the treatment efficiency is high, and the pain of patients can be reduced.

[0004] At present, in clinical treatment of sore throat and tonsillitis, usually the drug powder is brewed and directly applied to the painful part to relieve inflammation and relieve pain. In severe cases, drip injection is required. In this way, there are few drugs acting on the affected part, and the effect is slow. Some patients use a tube to blow the powder directly into the throat, but the blowing force is insufficient, and it is difficult to deliver the powder to the lesion, which does not have a therapeutic effect, adding pain to the patient and greatly increasing the work difficulty for medical staff. Direct local administration allows the drug to reach the infected part to play a role, but the existing operation is mostly treated by atomization, and the drug is inhaled into the respiratory tract by the patient's breathing. In this way, the drug easily enters the patient's lungs or other respiratory parts without lesions, causing damage to the patient. The existing drug delivery device is mostly a spray, and the drug will disperse after the spray is sprayed, and it still cannot reach the lesion directly, and this method is not suitable for powder, which makes the use of the drug have certain limitations. In addition, when the liquid or powder is delivered to the lesion, the drug is easily smeared unevenly, so that the part where the drug plays a role is relatively limited, and the drug cannot be absorbed in time, thereby reducing the drug treatment effect.
