Medical portable dry powder auxiliary suction device

Abstract

The invention discloses a medical portable dry powder auxiliary suction device. The medical portable dry powder auxiliary suction device comprises a shell, a moving shaft is fixedly mounted on the shell, an upper handle and a lower handle movably sleeves in the moving shaft, a compression spring is fixedly mounted on a spring seat, a fan-shaped folding air bag is fixedly mounted at the end, away from an upper shear blade and a lower shear blade, of the upper handle and the lower handle, a one-way air inlet valve is mounted on the fan-shaped folding air bag, an air inlet pipe communicates witha medicine cabin, a capsule placing cabin is fixedly mounted on the shell, and the capsule placing cabin is provided with a capsule placing opening. According to the medical portable dry powder auxiliary suction device, blades are used for shearing a capsule, thus dry powder medicine in the capsule can be thoroughly sucked, only a part of the dry powder can be taken in at every time of suction, choking of a patient is effectively reduced through multiple times of suction, meanwhile a user is assisted to take in, and thus a patient with weak pulmonary respiratory function can 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 Systemic therapeutic effect, there are many types of dry powder inhalation devices, which can be divided into single dose, reservoir type multi-dose, and mul...

[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 Systemic therapeutic effect, there are many types of dry powder inhalation devices, which can be divided into single dose, reservoir type multi-dose, and multiple unit doses according to dose; according to the storage method of drugs, they 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
