Abstract

The invention discloses a medical compression type atomizer and belongs to the technical field of medical instruments. The medical compression type atomizer comprises an air cylinder, an atomization device, a high-voltage direct-current motor and a power socket. The high-voltage direct-current motor is electrically connected with the power socket. The high-voltage direct-current motor is connected with the air cylinder in a transmission mode. The air cylinder is connected with the atomization device through a pipeline. The material cost of the high-voltage direct-current motor is much lower than that of an AC shaded pole motor, and the material cost is reduced by about 50%. The power consumption of the medical compression type atomizer is reduced by over 70% compared with a product adopting the AC shaded pole motor. The size and the weight of the medical compression type atomizer are reduced by over 50% compared with those of the product adopting the AC shaded pole motor.

Description

A kind of medical compression atomizer
Technical field
The present invention relates to a kind of nebulizer, be specifically related to a kind of medical compression atomizer.
Background technology
Medical vaporizer is mainly used in treating various upper and lower respiratory system diseases, as the disease being occurred 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 effective Therapeutic Method in respiratory system disease Therapeutic Method, adopt nebulizer that medical liquid atomizing is become to molecule, the mode that medicine sucks by breathing enters respiratory tract and pulmonary deposition, thereby reaches object painless, that effectively treat rapidly.Mainly be divided into two kinds: soniclizer and compression atomizer.
Soniclizer: utilize ultrasonic principle, by medical liquid atomizing.The aerosol apparatus of soniclizer is to droplet non-selectivity, so the drug particles major part producing only can be deposited on the upper respiratory tract such as oral cavity, throat, and because the deposition of pulmonary is little, can not effectively treat lower respiratory illness.Simultaneously, the droplet producing due to soniclizer is large, and atomization is fast, causes patient to suck too much steam, make respiratory tract humidifying, after the bronchial dry thick secretions of original Partial Blocking absorbs moisture in respiratory tract, expand, strengthen airway resistance, may produce anoxia phenomenon, and soniclizer can make medicinal liquid form the globule to hang on internal chamber wall, to lower respiratory illness poor effect, large to pharmaceutical requirements amount, wasting phenomenon.
Compression atomizer: also cry jetting type atomization, 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 producing drives liquid or other fluid to be ejected into together on obstacle, splashes towards periphery to make drop become vaporific microgranule to spray from escape pipe under high-speed impact.
Gas compression formula nebulizer has the following advantages:
1, efficient oil-free piston formula compressor, when atomization, do not need cooling water, daily non-maintaining, operation more simple and convenient; Former medicine atomization, does not need dilution, and clinical effectiveness is good; Almost there is no drug residue, utilization ratio of drug is high;
2, operation is used more conveniently, and product has one of 2 meters of trachea, and move place is large, sits, lies and can use, and atomizing component is light and handy, wears, hand steered convenience;
3, atomization is used former medicine atomization, the atomization quantity sucking within relative treatment time is suitable, being difficult for causing inner surface of trachea mucosa to send out rises, cause trachea to stop up, the granular superfine of atomization, and be difficult for collision combination, human body sucks comfortable, and can enter the trachea such as bronchus, pulmonary, clinical effectiveness is splendid, special suitable lower respiratory illness treatment;
4, pure mechanicalness product, fault rate is extremely low, and maintenance cost is low, long service life, general normal use 5~10 years.
Ultrasound atomizer, at therapeutic effect, in service life, operates the various reasons such as cleaning, and a lot of countries have thoroughly eliminated out market by ultrasound atomizer.In medical application fields, compression atomizer has been substituted soniclizer at present.
Medical compression atomizer in the market can be divided into interchange AC powered products and direct current DC powered products.The principle of two kinds of compressor nebulizers is identical, is all the motor driving air pump of interiors of products, and output high pressure draught sucks, treats respiratory tract disease by liquid medicine atomization for patient through specific atomising device.The difference of two kinds of compressor nebulizers is that AC interiors of products uses AC shaded-pole motor, and civil power (the AC shaded-pole motor of the corresponding different size of the voltage from different places such as China, Europe, North America) directly feeds product; DC product uses DC d.c. motor, and the unidirectional current (being generally no more than 36V) that need external or built-in transformator or Switching Power Supply, civil power is converted to the specified input of motor is for product.
Volume and the power consumption of the medical vaporizer product motor of AC shaded-pole motor itself are larger, cause volume, weight and the power consumption of its product entirety large, and efficiency of energy utilization is lower.Meanwhile, the material cost of AC shaded-pole motor itself is higher, and this also causes using the medical compressor nebulizer product cost of this motor higher.The medical vaporizer product of DC d.c. motor generally can only be operated under lower DC voltage, therefore needs external or built-in transformator or Switching Power Supply, and this just makes the cost of product increase and application scenario is restricted.
