Description

Medical portable dry powder auxiliary suction device

Technical Field

The invention relates to the technical field of medical instruments, in particular to a medical portable dry powder auxiliary inhalation device.

Background

The dry powder inhalation device is characterized in that the dry powder inhalation is administrated in a form of dry powder inhalation, the medicine is absorbed by abundant capillary vessels under lung and respiratory tract mucous membranes, the effect is very quick, the device is particularly suitable for protein polypeptide medicine administration, beta-adrenaline antagonist, anticholinergic agent, cortical hormone, potent anesthetic, anti-migraine and other small molecule medicines, and insulin, growth hormone, vaccine, new biotechnology products and other macromolecular medicines can also be prepared into lung administration preparations to play a local or systemic treatment role, the dry powder inhalation device has a plurality of types, and can be divided into: single dose, depot multiple dose, multiple unit dose; the storage modes of the medicines can be divided into: capsule, vesicular, depot; the power sources according to the device can be divided into: the dry powder inhalation devices of the inhalation air-flow driven type, the compressed air driven type, the battery motor driven type, which are commonly used at present, have disadvantages in that: the volume is great, carry inconveniently, and it is comparatively troublesome to use the operation, often needs the maintenance, and the medicine residual volume is higher in the device, except single dose type (like rotary inhaler etc.), all the other dry powder inhalation devices all can not used repeatedly, have caused the patient and repeatedly bought inhalation device, have aggravated patient's treatment expense, bring unnecessary economic burden for the patient.

In order to solve the above-mentioned problems, the scratch-proof dry powder inhaler of the prior art with application number "CN 201710946349.8" comprises a body, a groove for placing a capsule is arranged in the body; the air channel is arranged on the body and communicated with the groove; the button is connected with the spine part, the body is provided with a through hole communicated with the groove, the spine part is positioned in the through hole and is used for piercing the capsule in the groove, the aperture of the first end of the through hole is larger than that of the second end of the through hole, and the first end of the through hole is the end of the through hole close to the groove; the suction nozzle is provided with a suction nozzle through hole communicated with the groove of the body, the lower end of the suction nozzle through hole is provided with a filter screen, the lower end of the suction nozzle is connected with the upper end of the body, and the suction nozzle can rotate relative to the body; the cover body is removably arranged on the suction nozzle and completely covers the upper ends of the suction nozzle and the body. The scratch-proof dry powder suction device is simple in structure, and can effectively prevent the spine part from scratching the inner wall of the body.

Although the problem that the body is easily damaged by the conventional puncture is solved, the above dry powder inhaler still has obvious defects in the using process: 1. the device adopts a traditional puncture mode, the capsule opening mode easily causes incomplete suction of the dry powder medicine in the capsule, and a fine needle tube is easily blocked to influence the suction of the dry powder; 2. the device needs active inhalation of a user, and is difficult to use for a part of patients with weak lung function, so that the exertion of the efficacy of the medicine is influenced; 3. the medicine in the device is inhaled in a large dose in a short time, the large dose of dry powder is easy to gather into larger particles in the lung, large particles are attached to the inside of the bronchus, the treatment effect is influenced by a light person, and severe cough is caused by the heavy person to cause secondary damage to the lung.
