Problems solved by technology

[0006] The structure of the existing capsule dry powder inhaler is relatively complicated, the production cost is relatively high, and at the same time, the volume is too large and it is inconvenient to carry, and the general capsule piercing direction is perpendicular to the direction of the suction port, and a large suction force is required to inhale the inhaler. The powder is sucked clean, and it cannot be used or fully used for some patients with weak suction

Abstract

The invention discloses a pen-shaped capsule dry powder inhaler. The pen-shaped capsule dry powder inhaler comprises a main body. The pen-shaped 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; the other end of the main body is connected with a medicine support; a container for accommodating capsules is arranged in the medicine support; the lower part of the medicine support is provided with a through hole which is communicated with the container and the powder suction channel; and the medicine support is connected with a piercing device which can pierce the capsules arranged in the medicine support. The objective of the invention is to eliminate defects in the prior art. The pen-shaped capsule dry powder inhaler has the advantages of simple structure, convenient use, portable convenience and low requirements for suction forces.

Description

technical field [0001] The invention relates to a pen-shaped capsule dry powder inhaler. 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, quick onset, low to...
