Abstract

The invention discloses a rotatably-openable capsule dry powder inhaler. The rotatably-openable capsule dry powder inhaler comprises a main body. The rotatably-openable capsule dry powder inhaler is characterized in that a powder suction channel is arranged in the main body; one end of the main body is provided with a suction nozzle communicated with the powder suction channel; a medicine support used for accommodating capsules is arranged in the powder suction channel at the other end of the main body; the main body is provided with a piercing device which is located above the medicine support and can pierce the capsules arranged in the medicine support; and a turnover mechanism which can make the piercing device and the medicine support separated from each other is arranged between the piercing device and the main body. The objective of the invention is to eliminate defects in the prior art. The rotatably-openable capsule dry powder inhaler has the advantages of simple structure and convenient use, and can be opened in a turnover manner.

Description

technical field [0001] The invention relates to a capsule dry powder inhaler which can be rotatably opened. Background technique [0002] Since the inhaler invented by Charles Thiel in the mid-1950s, medical devices that deliver inhaled drug aerosols to patients have been used in the treatment of asthma and chronic obstructive pulmonary disease. [0003] Compared with oral administration and subcutaneous injection, inhalation administration has obvious advantages. Due to the large mucous membrane surface area of ​​the human nasal cavity, bronchi and lungs, the human respiratory tract has a total of 23 bifurcations, and the adult alveolar surface area can be as high as 140 square meters. The alveolar wall is very thin and surrounded by a large number of capillaries. The drug particles can quickly pass through the alveolar mucosa tissue and directly enter the blood circulation. It has the advantages of no gastrointestinal degradation, no liver first-pass effect, small dose, ...
