Description
Technical Field
The utility model relates to the technical field of pulmonary drug delivery systems, in particular to a capsule type medicinal powder inhaler.
Background
Pharmaceutical powder inhalers are an important component of pulmonary drug delivery systems. The pulmonary route of administration, which has no hepatic first-pass effect due to its large absorption area, has received extensive attention in the field of drug delivery system development, and its clinical application has also progressed from traditional local treatment of asthma to systemic treatment. Unlike the general route of administration, pulmonary administration requires dispersion, nebulization, and pulmonary delivery of the drug by means of a special inhalation device, which plays a key role in the pulmonary delivery system.
The action mechanism of the capsule type medicine powder inhaler is that micronized medicine and a carrier are filled into gelatin capsules, the capsules are put into the medicine powder inhaler when in use, the capsule shells are damaged in different modes, medicine powder is released from the damaged capsule shells along with airflow when a patient inhales, the medicine powder is inhaled into a respiratory system of a human body, the capsule shells after the device is taken out and discarded after use, and the device is cleaned and left for next use. The device has the advantages of relatively independent design and medicament dosage form and strong adaptability. The medicine powder is driven to the respiratory system of human body by the airflow brought by the inhalation action of human body, so the stability and uniformity of the airflow flow can directly influence the reliability of the medicine administration action.

The small holes are designed under the screen, and the purpose of the small holes is to form an air flow channel which does not pass through the capsule chamber, and the air can directly enter the suction nozzle pipe to drive the medicinal powder to enter the human body, which is equivalent to reducing the integral air resistance of the equipment. A correction of the flow resistance of the inhaler itself to accommodate users with different lung capacities and different particle sizes and doses of powder.
Specifically, the bottom plate is provided with 4 small holes, and the diameters of the small holes are smaller than 0.87 mm.
Specifically, the center of the bottom plate is a step surface, the height of the step surface is lower than that of other parts of the bottom plate, a circular mounting hole is formed in the step surface, the capsule chamber is mounted on the bottom plate through the circular mounting hole, and the small hole is formed in the step surface.
According to the technical scheme, the design of the step surface enables the circular mounting hole to have a certain thickness, and the capsule chamber is convenient to mount.
Specifically, the bottom plate is oval, be provided with 4 air inlet on the bottom plate, air inlet is the bar through-hole.
Specifically, the vacuum cleaner further comprises an upper cover which is hinged on the rotating shaft and is positioned above the suction nozzle to open and close the suction nozzle.
Through the utility model provides a capsule type powder inhaler can bring following at least one beneficial effect:
1. the air inlet is moved to the plane of the bottom plate and at the same time the nozzle understructure is modified to expose the air inlet. The bottom plate and the capsule opening mechanism close the bottom shell, so that outside air can only enter the bottom shell through the uniformly distributed air inlets formed in the bottom plate and then enters the population through the capsule chamber, the screen and the suction nozzle pipe. Because the air inlet is controlled to enable the air to uniformly enter the bottom shell, the stability of the air flow is greatly improved.
2. The small holes are designed under the screen, and the purpose of the small holes is to form an air flow channel which does not pass through the capsule chamber, and the air can directly enter the suction nozzle pipe to drive the medicinal powder to enter the human body, which is equivalent to reducing the integral air resistance of the equipment. A correction of the flow resistance of the inhaler itself to accommodate users with different lung capacities and different particle sizes and doses of powder.
3. The design of the step surface ensures that the circular mounting hole has certain thickness, thereby being convenient for the installation of the capsule chamber.
