Description

Medical treatment respiratory tract medication mist inhaler

This utility model belongs to the apparatus of medium being imported human body, particularly a kind of with the medicine mist from the oral cavity, nasal cavity sucks the medical apparatus and instruments of respiratory tract.

At present, for respiratory tract disease, often adopt the treatment of medicine mist inhalation, be about to medical liquid atomizing, a kind of medical metered-dose inhaler commonly used (being called for short MDI) relies on patient respiration, and the medicine mist is sucked the human respiratory tract until alveolar, is used for the respiratory tract topical medications.Chinese patent " ZL94244708.5 medicinal aerosol suction apparatus " provides a kind of aerosol suction apparatus, adopt air bag to store the medicine mist, patient uses the flat valve of sucking air bag, along with patient respiration, aerosol can be sucked respiratory tract, can accomplish sprays carries out synchronously with air-breathing, very convenient.But speed and dose that each patient sucks aerosol are difficult for grasping, and suction velocity is too fast, instead can make the air flue closure of pathological changes, and medicine is difficult to enter the arrival lesions position, affects the treatment.Simultaneously, suction apparatus only is suitable for a mouthful suction, has only a kind of bore with the medicament connecting portion, can not be used for the medicament of plurality of specifications.

The purpose of this utility model is, designs and produces a kind of medical respiratory tract medication mist inhaler, and the air-breathing diaphragm of design ring-type is to improve air-breathing sensitivity; Exhaling hole is designed to light section, to produce internal resistance, makes the expiration supercharging, improves curative effect; On the socket cover that connects aerosol, the air-breathing whistle is set, instructs air-breathing speed; And, connect the aerosol of different size at two kinds of sockets of the textural design of structure; Design two kinds of haustoriums, suck simultaneously, make that the inhaler scope of application is wideer, suck the easier grasp of main points, make things convenient for physician guidance applicable to oral cavity suction or mouth and nose chamber; All be easier to operation for age small baby and old old man.

The technical solution of the utility model is following realization; A kind of medical respiratory tract medication mist inhaler comprises storage mist suction tube, medicament socket cover, haustorium lid, haustorium, and storage mist suction tube and haustorium lid connecting portion are provided with inner edge bayonet socket convex tendon, can closely peg graft; Medicament socket cover center is provided with concentric inside and outside two oval jacks, has radial reinforcement to be connected with the socket cover periphery supporting around the jack, is provided with the air-breathing whistle on medicament socket cover end face; The end face of haustorium lid is provided with breather cheek valve, and unidirectional valve seat is the sphere of cross bearer supporting, and the air-breathing diaphragm of ring-type covers on the sphere, and periphery uses the pressure ring pressing and fixing in haustorium hd top face periphery annular groove; Haustorium has oral nose mask haustorium and oral cavity to insert two kinds of haustoriums (being called for short oral nose mask, mouthpart): the profile of the oral nose mask of being made by the high elasticity soft high molecular polymer is bell shape, subsides cover on mouth and wing of nose position, the oral nose mask middle part is the oral area through hole, exhaling hole is established in oral area through hole top, exhaling hole is two scallop holes arranged side by side, be provided with unidirectional expiration diaphragm, oral nose mask and haustorium lid link are provided with annular groove, are fastened on the flange of haustorium lid; The mouthpart of being made by the high elasticity soft high molecular polymer is tapered tube, and an end is for inserting the oblateness in the mouth, and the mouthpart side is provided with expiratory valve, and mouthpart and haustorium lid link are provided with annular groove, are fastened on the flange of haustorium lid, are provided with the mouthpart dust cap.

Using method of the present utility model is, medical metered-dose inhaler (being called for short MDI) is connected on the oval jack of the medicament socket cover of storing mist suction tube one end, the medicine mist can spray in the storage mist suction tube, the oral nose mask button that covers clamping at haustorium covers on the patient nose and mouth, can rely on patient's respiratory movement, the medicine mist is sucked respiratory tract, until alveolar.When air-breathing, the medicine mist backs down the air-breathing diaphragm of ring-type, and the medicine mist passes through from the gap of the cross bearer of unidirectional valve seat, enters the oral cavity; During expiration, exhale, back down unidirectional expiration diaphragm and pass through from two scallop holes arranged side by side of the exhaling hole of oral nose mask.When air-breathing excessive velocities, the sound will be sent in the air-breathing whistle on the socket cover, reminds patient suitably to slow down air-breathing speed.For the adult, the oral nose mask of useful size large size or mouthpart, for teenager, the oral nose mask of useful size trumpet or mouthpart.

The utility model has the advantages that: owing to using medical metered-dose inhaler when (being called for short MDI), mist is sprayed, store to the medicine mist by this utility model medical treatment respiratory tract medication mist inhaler earlier, and then be inhaled into mouth and nose, and is therefore easy to use.The air-breathing diaphragm of ring-type is highly sensitive, makes things convenient for the patient of inhalation mist, particularly inspiratory dyspnea; Exhaling hole is designed to light section, and the internal resistance of generation makes the expiration supercharging, the treatment of favourable dysfunction of ventilation; The air-breathing whistle is set, can instructs inhalation method; Medicament socket cover center is provided with concentric inside and outside two oval jacks, the shape of the mouth as one speaks of the medical metered-dose inhaler that applicable different pharmaceutical factories produce; Storage mist suction tube is bayonet socket and is connected with haustorium lid, oral nose mask, is convenient to dismounting, cleaning and sterilizing.Enlarged the age bracket that adopts medical metered-dose inhaler medication mist agent inhalation treatment disease, infant or old old man make things convenient for use.Be applicable to the medicine mist inhalation apparatus of respiratory tract disease.
