Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, specifically relate to a kind of medical nebulizer and be difficult to articulate.
Background technology
Medical vaporizer is mainly used in the various respiratory system diseases up and down of treatment, like the disease that is taken place in trachea, bronchus, alveolar, the thoracic cavities such as flu, heating, cough, asthma, laryngopharynx swelling and pain, pharyngitis, rhinitis, bronchitis, pneumoconiosis.Atomization inspiration treatment is a kind of important and efficacious therapy method in the respiratory system disease Therapeutic Method; Adopt nebulizer that medical liquid atomizing is become molecule; Medicine gets into respiratory tract and pulmonary deposition through breathing the mode that sucks, thereby reaches purpose painless, that effectively treat rapidly.
The atomizing principles that uses at present mainly contains two kinds, and a kind of is soniclizer, and a kind of is the jetting type nebulizer.The jetting type atomizing is according to venturi (Venturi) ejector principle; Utilize compressed air to pass through the tiny mouth of pipe and form high velocity air; The negative pressure that produces drives liquid or other fluid is ejected on the obstacle together, under high-speed impact, splashes towards periphery to make drop become vaporific microgranule to spray from escape pipe.
Nebulizer generally comprises atomizing cup and is difficult to articulate part, and atomizing cup is used for producing atomizing vapour; The part of being difficult to articulate is to contact with patient's mouth, convenient nebulizer and the patient respiration of deriving.Japan patent of invention TOHKEMY 2007-97830A discloses a kind of part of being difficult to articulate of typical jetting type sprayer unit; As shown in Figure 1; Being difficult to articulate comprises medicine mist export mouth 105, expiration outlet 106, medicine mist introducing port 155, and constituting between medicine mist introducing port 155 and the medicine mist export mouth 105 derives path 10 4.When air-breathing, atomizing vapour sucks from medicine mist introducing port 155, gets into human body through medicine mist export mouth 105, during expiration, gives vent to anger outside 106 discharges of expiration outlet are difficult to articulate.The whole atomizing vapor outlet position of being difficult to articulate and being enclosed within atomizing cup.
Existing nebulizer is difficult to articulate and is had following defective: the liquid after the liquefaction of atomizing gas or the saliva of user can flow backward to the medicinal liquid of atomizing cup from deriving path 10 4, medicinal liquid is formed pollute, and influence the cleaning of medicinal liquid, reduce therapeutic effect.
Summary of the invention
The technical problem that the present invention will solve overcomes above defective exactly, proposes being difficult to articulate of a kind of medical vaporizer, and adopts this medical vaporizer of being difficult to articulate, and preventing to be difficult to articulate, the port of export produces or the liquid of entering flows backward in the atomizing cup.
Technical problem of the present invention is achieved through following technical scheme.
Being difficult to articulate of this medical nebulizer; Comprise a body; Said body has atomizing vapour access port, atomizing vapour export mouth, expiration outlet; Body inner space by between atomizing vapour access port and the atomizing vapour export mouth constitutes the derivation passage, and said expiration outlet is opened on the tube wall of deriving passage; Also be provided with fluid collection device in the said derivation passage.
Said fluid collection device is to be installed in the baffle plate that stops of deriving vias inner walls.
Said derivation passage comprises first gas channel, second gas channel, connects the corner passage of first gas channel and second gas channel; Said first gas channel connects atomizing vapour access port; Said second gas channel connects atomizing vapour export mouth; Said expiration outlet is opened on the tube wall of the second gas channel section, and said fluid collection device is positioned at the end near the corner passage of second gas channel.
Said expiration outlet is positioned at the end near the corner passage of second gas channel, and said fluid collection device is between expiration outlet and corner passage.
Said first gas channel, second gas channel and corner passage are structure as a whole.
This medical nebulizer; Comprise and produce being difficult to articulate of the atomize atomizing cup of vapour and the vapour that will atomize derivation atomizing cup; Said being difficult to articulate comprises that a body, said body have atomizing vapour access port, atomizing vapour export mouth, expiration outlet, and said nebulizer access port connects the outlet of atomizing cup; Body inner space by between atomizing vapour access port and the atomizing vapour export mouth constitutes the derivation passage, and said expiration outlet is opened on the body tube wall of deriving passage; Also be provided with fluid collection device in the said derivation passage.
Said fluid collection device is to be installed in the baffle plate that stops of deriving vias inner walls.
Said derivation passage comprises first gas channel, second gas channel, connects the corner passage of first gas channel and second gas channel; Said first gas channel connects atomizing vapour access port; Said second gas channel connects atomizing vapour export mouth; Said expiration outlet is opened on the tube wall of second gas channel, and said fluid collection device is positioned at the end near the corner passage of second gas channel.
Said expiration outlet is positioned at the end near the corner passage of second gas channel, and said fluid collection device is between expiration outlet and corner passage.
Said first gas channel, second gas channel and corner passage are structure as a whole.
The beneficial effect that the present invention and prior art contrast are had is: in being difficult to articulate, be provided with fluid collection device; The saliva of liquid and user after the gas liquefaction of preventing to atomize flows backwards in the entering atomizing cup; Avoid liquid medicine contamination, guaranteed the cleanliness factor of medicinal liquid, improved therapeutic efficiency.
