Problems solved by technology
However, due to the complexity of the people who use the inhaler, such as the different symptoms of the patient, the physiological differences between children and adults, etc., it is necessary to design the inhalation device of the inhaler according to different users, so that it has different inhalation functions. Air flow rate, to better meet the needs of people in different situations, so that more drugs can be deposited in the lungs of patients, so that the drugs can achieve better bioavailability and reduce the side effects of drugs
In order to solve this problem, people have developed a variety of inhalation devices, such as inhalation devices driven by electric motors to release drugs, with self-inflating spacer tanks, and inhalation devices that drive and release drugs through pistons arranged on the spacer tanks, However, most of these drug inhalation devices of the drug inhaler have complex structures, are difficult for patients to operate, are cumbersome to use, and are expensive, and are not easy to popularize and use.

The present invention discloses a dual-air path inhalation device of a drug powder inhaler, which includes a drug storage chamber which is communicated with a suction nozzle of the inhaler, a main air path is arranged on the side wall of the drug storage chamber, and the bottom end of the drug storage chamber is provided with an assisted air path. The present invention has simple structure and easy usage, which can be applicable to the inhalation therapy of the patients with the different situations for use.
Description
technical field [0001] The invention relates to a medical device, in particular to a double-air-path inhalation device of a drug powder inhaler which can be used for clinical inhalation therapy in a hospital. Background technique [0002] At present, inhalation therapy has become an important method of drug administration for various diseases such as asthma in hospital clinics, so drug inhalers have also been widely developed and applied. But because the crowd who uses the inhaler is more complicated, such as the patient's illness is different, the physiological difference between children and adults, etc., therefore, it is necessary to design the inhalation device of the inhaler according to different users, so that it has different inhalation. The air flow rate can better meet the needs of people in different situations, so that more drugs can be deposited in the lungs of patients, so that the drugs can achieve better bioavailability and reduce the side effects of drugs. ...
