Abstract
The utility model relates to the technical field of medical appliances, in particular to an aerosol inhaler for use with medicinal aerosol. The aerosol inhaler comprises a base (1), a one-way valve, an aerosol storage barrel (3) and a suction nozzle (4), the base (1) is provided with a hole communicated with an aerosol spray nozzle, the front of the base (1) is provided with the aerosol storage barrel (3) capable of holding the aerosol, the front portion of the aerosol storage barrel (3) is provided with the suction nozzle (4), the diaphragm (2) type one-way valve is arranged between the aerosol storage barrel (3) and the suction nozzle (4), and a cover (5) is disposed on the outer side of the suction nozzle (4). The one-way valve comprises the diaphragm (2) and a check rack (6), the front of the suction nozzle (4) is flat circular while the rear thereof is circular and is in threaded connection with the aerosol storage barrel (3), and sprayed aerosol entering the aerosol storage barrel (3) is in a suspended state. Patients can complete quantitative aerosol feeding of medicinal aerosol by repeatedly breathing towards the inside of the aerosol storage barrel (3), thereby avoiding acrimony of feeding pressure and propellents of the aerosol and increasing the absorption of the drug by a patent. In addition, the aerosol inhaler has the advantages of simple and reasonable structure, convenient use and the like.
Description
Technical field
This utility model relates to a kind of technical field of medical instruments, specifically a kind of aerosol medicine absorber that is used for cooperating the medicinal aerosol use.
Background technology
Aerosol is meant that medicine and propellant are contained in the pressure vessel together, borrow the pressure of propellant, with the preparation of content ejection during use.Ejecta mainly is vaporific gas collosol state, so have another name called aerosol.Aerosol not only can be used for topical therapeutic but also can be applied to respiratory tract absorbing through alveolar membrane, and played the whole body therapeutic effect.The advantage of aerosol: 1. easy to use, prove effective rapidly, medicine can directly arrive site of action or absorption site, has fairly obvious quick-acting effects and positioning action, especially has the irreplaceable advantage of other dosage forms aspect respiratory tract administration; 2. medicine cleaning and aseptic condition can be kept, and stability of drug can be improved.3. reduce the pain of local application, use as burn and sensitive skin patient; 4. Pen Chu droplet is small, can go directly site of action or absorption site, and be evenly distributed, dosage is less, so side effect is also little.But when the patient uses aerosol at present, suction-type aerosol particularly, propellant is taken quantitative medicament active composition out of, directly enter patient's oral cavity by the aerosol ejection, owing to have the zest of certain pressure and propellant, particularly child patient owing to pressure and zest, often can not absorb medicament active composition fully, thereby not reach the effect of treatment when using aerosol.
Summary of the invention
In order to overcome above-mentioned defective, it is a kind of simple and reasonable, easy to use that this utility model provides, and avoided the administration pressure of aerosol and the zest of propellant, improves the aerosol medicine absorber of patient to drug absorption.
The technical solution adopted in the utility model is: a kind of aerosol medicine absorber, it is characterized in that: comprise base, check valve, medicine-storing tube and suction nozzle, base is provided with the hole with the aerosol spout connection, the anterior setting of base can be held the medicine-storing tube of medicine, the front portion of medicine-storing tube is provided with suction nozzle, between medicine-storing tube and suction nozzle, be provided with diaphragm type one-way valve, lid arranged in the suction nozzle arranged outside.
Described check valve comprises diaphragm and check slide, described diaphragm is arcuation backward, its middle part is provided with the hole, its limit portion is connected with medicine-storing tube by suction nozzle, described check slide middle part is provided with the corresponding baffle plate of shape in the hole on shape and the diaphragm, and baffle plate is slightly larger than this hole, and baffle plate is connected with medicine-storing tube by connection strap, baffle plate is close to the rear portion in diaphragm-operated hole, and baffle plate, diaphragm, medicine-storing tube and base form a relative airtight space.
Described suction nozzle front portion is oblate, the rear portion for circular and with medicine-storing tube for being threaded, be provided with from snap close in the screw thread terminal.
The hole that is communicated with on the described base, with aerosol is provided with buzzer.
This utility model is arranged on the aerosol front portion, the medicine that aerosol sprays during use enters medicine-storing tube through base and is suspended state, the expulsion pressure of aerosol and the zest of propellant obtain buffering and reduce in the special tube of storage, the patient contains suction nozzle in the inlet, one-way valve opens when air-breathing, medicine enters patient oral cavity and pulmonary, during expiration, check valve is in closed condition, the active ingredient of pharmaceutical runs off in the medicine-storing tube, breathe the dosed administration of finishing medicinal aerosol repeatedly through the patient, avoided the administration pressure of aerosol and the zest of propellant, improve the patient drug absorption; One-way valve designs of the present utility model becomes to be made up of diaphragm and check slide, and simple in structure, air-breathing unobstructed, non-return is effective; Suction nozzle is provided with top is arranged to oblateness, be beneficial to patient's revision and contain in the inlet.
Description of drawings
Fig. 1 is a structural representation of the present utility model
The specific embodiment
Now in conjunction with the accompanying drawings this utility model is further described, Fig. 1 is a kind of embodiment of the present utility model, comprise base 1, check valve, medicine-storing tube 3 and suction nozzle 4, base 1 is provided with the hole with the aerosol spout connection, base 1 anterior setting can be held the medicine-storing tube 3 of medicine, medicine-storing tube 3 is generally circular cylinder, and the base 1 in the present embodiment is provided with cannelure, and the rear end of medicine-storing tube 3 is inserted in the cannelure and is connected with base 1.The front portion of medicine-storing tube 3 is provided with suction nozzle 4, is provided with diaphragm type one-way valve between medicine-storing tube 3 and suction nozzle 4, covers 5 in suction nozzle 4 arranged outside.Suction nozzle 4 front portions in the present embodiment are oblate, the rear portion for circular and with medicine-storing tube 3 for being threaded, be provided with from snap close in the screw thread terminal.
