Description

A internal medicine atomizing treatment equipment for respiratory disease
Technical Field
The invention belongs to the technical field of internal medicine instruments, and particularly relates to internal medicine atomization treatment equipment for respiratory diseases.
Background
Chinese patent CN108126259A discloses a "medical atomizer", which comprises an atomizing tank, an atomizing core and a breathing mask, and when the respiratory diseases need to be atomized, the mask is carried on the face of a patient, so that the patient can inhale the mist in the mask into the respiratory tract through the nose. However, the structure is not suitable for the simultaneous occurrence of nose blockage and throat inflammation, and if the nose and the mouth inhale mist directly, the mist reaches the throat less, and water drops are easily formed in the oral cavity, so that the atomization effect is poor.
Disclosure of Invention
The invention provides medical atomization treatment equipment for respiratory diseases, which can well treat nasal cavities and throats simultaneously in order to overcome the defects of the prior art.
In order to achieve the purpose, the invention adopts the following technical scheme: a medical atomization treatment device for respiratory diseases comprises
The atomizer is provided with a storage channel;
the strap is arranged on the atomizer and used for limiting the atomizer on the neck of a user;
the mouthpiece is arranged on the atomizer and used for conveying atomized mist outwards;
the liquid blocking structure is used for preventing saliva from flowing into the atomizer when the atomizer is used;
the mask is detachably connected with the mouthpiece through a dismounting structure;
the air guide port is arranged on the mouthpiece and used for communicating the mouthpiece and the mask, and a plug part used for closing the air guide port is detachably connected to the air guide port.
According to the invention, the face mask is detachably connected to the mouthpiece, so that when the nasal cavity and the throat need to be subjected to atomization treatment simultaneously, the mouthpiece can be bitten into the mouth, the face mask is covered on the face, and mist is inhaled simultaneously through the nose and the throat, so that good treatment is achieved, and the conditions that the throat treatment effect is poor when the face mask is used for treating the lower pharynx and the nasal cavity cannot be treated when the mouthpiece is used for treating the lower pharynx are effectively avoided; when the mouth piece is bitten, the mask can cover the face of a patient without being hung on ears or the head through a hanging rope, so that the use comfort is higher;
moreover, the atomizer can be hung on the neck through the arrangement of the belt, so that the user can vacate two hands for doing other things without holding the atomizer; compared with a hanger-type atomizer, the neck bearing force is larger on the neck, the stressed area of the neck is larger, and the uncomfortable feeling of tightening ears is not easy to occur; secondly, through having set up the fender liquid structure, the saliva that gets into the mouthpiece can be blockked by the fender liquid structure, can not get into to the atomizer in, has effectively avoided the user to carry out atomizing in-process when biting the mouthpiece, and the saliva flows into to the atomizer and the influence atomization effect that appears or the later stage condition of breeding the bacterium.
Furthermore, the air guide port is arranged on the side wall of one side of the mouth piece which is arranged upwards, and the plug piece is in threaded connection with the air guide port; the air guide port is closer to the position of the nose.
Further, an air bag part is arranged on the face mask, and the air bag part can be attached to the face of a user; guarantee the flexible fit between face guard and the face, reduce the gap of both spare, reduce the outside volume of effluvium of fog, further improve the effect of fog inhalation.
Furthermore, a circle of clamping groove for mounting the air bag part is arranged on the face mask, and a plurality of circles of grooves are arranged on the inner wall of the clamping groove; the groove can contain adhesive materials such as glue and the like, so that the air bag can be more firmly arranged on the face mask.
Furthermore, the dismounting structure comprises a blocking part arranged on the mouthpiece and a flexible ring arranged on the mask; the position of the face mask can be limited by the blocking part, and when the face mask abuts against the blocking part, the face mask can not move backwards any more, so that the face mask can just cover the face when a user bites the mouthpiece.
Furthermore, the mouthpiece comprises an air duct communicated with the air outlet of the atomizer and a mouthpiece body matched with the air duct; the air duct and the mouthpiece body are respectively arranged in an L-shaped structure, and the liquid blocking structure comprises a first liquid blocking part arranged in the mouthpiece body and a second liquid blocking part arranged on the air duct; the air duct and the mouthpiece are both arranged in an L-shaped structure, so that when the atomizer is hung on the neck, the mouthpiece can be at a better angle even the mouth of a user, and the posture of gripping the mouthpiece is more comfortable; through the setting of two sets of fender liquid parts, carry out good the blockking to the saliva that enters into in the mouthpiece, effectively avoid appearing the condition that saliva enters into in the atomizer.
Further, the air duct comprises a duct body and an expansion mask screwed on the duct body; the bottom of the mask expanding cover extends upwards to form an extension part, an air channel is arranged on the extension part, and the mouthpiece body is sleeved on the extension part; the atomizer also comprises a locking device for locking the positions of the bite mouth body and the mouth expanding cover; the connection between the bite mouth body and the mask expanding cover is realized through the arrangement of the extension part, so that the connection is firmer; secondly, through the setting of locking device for also can realize very firm connection between bite mouth body and the gauze mask, and then effectively avoid the user to rotate the neck when biting the bite mouth body and cause bite mouth body and gauze mask to throw off, reduce the fault rate of atomizer.
In summary, the invention has the following advantages: can dismantle on the difficult mouth of a person and be connected the face guard, and then when nasal cavity and throat need carry out atomization therapy simultaneously, can sting the difficult mouth to the mouth, the face guard cover is established to facial on, inhales to the fog simultaneously through nose and throat to reach good treatment, effectively avoid adopting the face guard to treat down the throat treatment poor, the condition of the unable treatment of nasal cavity under the adoption difficult mouth of a person's mouth treatment.
