A medical portable dry powder assisted inhalation device

Abstract

The invention discloses a medical portable dry powder auxiliary inhalation device, which comprises a casing, a movable shaft is fixedly installed on the casing, an upper handle and a lower handle are movable sleeved in the movable shaft, and a spring seat is fixedly installed with a Squeeze the spring, the upper handle and the lower handle are fixed with a fan-shaped folding air bag at the end away from the upper scissors and the lower scissors, and a one-way air intake valve is installed on the fan-shaped folding air bag, and the air intake pipe communicates with the medicine cabin. The housing is fixedly equipped with a capsule storage cabin, and a capsule storage opening is opened on the capsule storage cabin. The invention uses a blade to cut the capsule, so that the dry powder medicine in the capsule can be completely inhaled, so that each inhalation is only Part of the dry powder can be inhaled, and the patient's choking is effectively reduced through multiple inhalations. At the same time, it assists the user in inhaling, so that patients with weak lung respiratory function can also be effectively treated.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a medical portable dry powder assisted inhalation device. Background technique [0002] The characteristic of the dry powder inhalation device is that it is administered in the form of dry powder inhalation. The drug is absorbed through the rich capillaries under the lung and respiratory tract mucosa, and the effect is very fast. It is especially suitable for the administration of protein polypeptide drugs, β-adrenergic antagonists, Anticholinergic agents, corticosteroids, strong anesthetics, anti-migraine and other small molecule drugs, and macromolecular drugs such as insulin, growth hormone, vaccines and new biotechnology products can also be made into pulmonary drug formulations, which can play a role in local or There are many types of dry powder inhalation devices for systemic therapeutic effects, which can be divided into single dose, reservoir type multi-dose, and...

[0002] The characteristic of the dry powder inhalation device is that it is administered in the form of dry powder inhalation. The drug is absorbed through the rich capillaries under the lung and respiratory tract mucosa, and the effect is very fast. It is especially suitable for the administration of protein polypeptide drugs, β-adrenergic antagonists, Anticholinergic agents, corticosteroids, strong anesthetics, anti-migraine and other small molecule drugs, and macromolecular drugs such as insulin, growth hormone, vaccines and new biotechnology products can also be made into pulmonary drug formulations, which can play a role in local or There are many types of dry powder inhalation devices for systemic therapeutic effects, which can be divided into single dose, reservoir type multi-dose, and multiple unit doses according to the dose; according to the storage method of the drug, it can be divided into: capsule type, vesicle type, and reservoir type; The power source of the device can be divided into: inhalation air-driven type, compressed air-driven type, and battery motor-driven type. The disadvantages of the commonly used dry powder inhalation devices are: large size, inconvenient to carry, troublesome to use and operate, and often need maintenance. The drug residue in the device is relatively high. Except for the single-dose type (such as rotary inhaler, etc.), the rest of the dry powder inhalation device cannot be reused, causing patients to purchase the inhalation device repeatedly, which increases the treatment cost of the patient and brings unnecessary costs to the patient. economic burden

[0004] Although it solves the problem that the traditional puncture is easy to damage the body, the above-mentioned dry powder inhaler still has obvious defects during use: 1. The above-mentioned device adopts the traditional puncture method, and the opening method of the capsule is easy to cause the dry powder drug in the capsule to be sucked out Incomplete, and the slender needle tube is easy to block, which affects the inhalation of dry powder; 2. The above-mentioned device requires active inhalation by the user. For some patients with weak lung function, it is difficult to use, thus affecting the efficacy of the drug; 3. The above-mentioned The drug in the device is inhaled in a large dose in a short period of time. The large dose of dry powder is easy to gather into larger particles in the lungs. secondary damage to the
