Description

Chew the quantitative aerosol apparatus of barrel formula

This utility model belongs to medicine instrument, is specifically related to a kind of spray delivery apparatus that diseases such as oral cavity, throat, trachea are used for the treatment of--chew the quantitative aerosol apparatus of barrel formula.

Acute and chronic pharyngitis is a kind of very general commonly encountered diseases, frequently-occurring disease, and the trouble in the general population is sent out rate and surpassed 30%.This type of disease mainly shows as local symptom.If long-term whole body (oral or injection) administration is influential to functions such as conscience kidneys unavoidably, and the curative effect of topical is direct and significant often.The medicinal sprayer that is generally used for treating oral cavity, throat and respiratory tract disease at present has two kinds: a kind of is that the medicine grind into powder is packed in the plastic bottle, by the pressure that the extruding plastic container is produced, medicated powder is coated on the affected part mucosa.This method, medicine is difficult to permeate through cell membranes and is absorbed, and causes on the contrary sometimes that foreign body is choked to cough; And no proportioning device is difficult to the control dosage; During the spray medicine, hands and container all will stretch into the oral cavity, use inconvenience and don't health.Second kind is aerosol spray, exactly the adding of propellant such as fluorine Lyons is filled in the hermetic container of medicine, after the vibration, the pressing spraying, medicine forms fine particles under the effect of propellant, enter air flue with breathing.This method, drug absorption is better, also can be accurately quantitative, but in recent years, a large amount of clinical practices prove that propellant such as the fluorine Lyons of being added bring certain poison to pay effect to human body.

This utility model is at existing oral cavity, and the shortcoming of disease topical apparatuses such as throat, trachea provides a kind of and can make medical liquid atomizing, and uniform distribution absorbs, and quantitatively accurately, can arbitrarily change the aerosol apparatus of direction simultaneously.This aerosol apparatus is used the principle of chewing bucket and pressurization atomizing, need not in use by propellant, therefore almost pays effect without any poison to human body.It is highly desirable to be used for the treatment of diseases such as oral cavity, throat, trachea.

The oral cavity that is used for the treatment of of the present utility model, throat, diseases such as trachea chew the quantitative aerosol apparatus of barrel formula, comprise the drug storage bottle, pipette, catheter, it is first-class to spray, it is characterized in that at the drug storage bottle bottleneck spray cap that is spirally connected, center at spray cap is connected with neck bush by tight fit, the quantitative bucket that the neck bush central lower is from top to bottom shunk gradually by tight fit interlocking one, quantitatively a catheter is established at the enlarged center of bucket, between two muscle floating piston is set up and down at catheter bottom sliding sleeve one spring, between the overflow core of quantitative bucket constriction and catheter lower end, spring is set, in the reverse taper hole of quantitative bucket lower end, establish movable pearl, quantitatively the lower end of the bucket pipette of pegging graft; The lid that presses that the side of planting in the annular space above spray cap has jack inserts rotating pipe joint in pressing the jack of lid, rotate catheter in the other end insertion one of rotating pipe joint, and the other end grafting one of catheter has the fog-spray nozzle that atomizing is chewed.

Because rotating pipe joint is embedded in and presses in the jack that covers side, so can on the vertical plane direction, do 360 ° of rotations by the fog-spray nozzle that rotating pipe joint drives, in addition owing to press lid and be embedded in the annular space on the spray cap, press lid and can drive fog-spray nozzle by rotating pipe joint and do 360 ° of rotations of horizontal direction; Owing to press lid and spray cap, rotating pipe joint with press lid, rotating pipe joint with rotate catheter, rotate catheter and fog-spray nozzle, pipette all adopts inserted connected mode with quantitative bucket, so dismounting, assembling, make all very convenient.It is the key factor that influences spray effect that atomizing in the fog-spray nozzle is chewed, and adopts laser boring technology, is made into the holes of the different sizes of bore, and medicinal liquid is atomized when depressing by this hole adding, and the mean particle dia after the atomizing can be controlled in the 5-100 micrometer range; The hollow space that atomizing is chewed can be set as cylindrical or the turbination hole as required.If be set as the cylindrical pore, after then medicinal liquid was chewed by atomizing, the spraying that is produced did not almost have the impelling angle; If be designed to the turbination hole, the impelling angle almost equates with conical drift angle, according to this principle, can design 30 °--60 ° of jet angles, and to adapt to the needs of different spraying positions and spread of spray.

Of the present utility model be used for the treatment of diseases such as oral cavity, throat, trachea chew the quantitative aerosol apparatus of barrel formula, utilize itself architectural feature to realize the purpose of atomizing spray medicine, overcome many shortcomings that existing various medicinal sprayers exist.Because every pressing once, the liquid dose of ejection is constant accurately, has guaranteed the safety of dosage; Spraying granule is trickle and even, the mucosa good absorbing, and the bioavailability height is fit to the physiological requirement of oral cavity, throat and trachea administration; Fog-spray nozzle can cover with rotating pipe joint and pressing does 360 ° freely rotates on horizontal plane and vertical plane, the variable jet angle chewed of atomizing in addition, and foot is in satisfying the needs that different lesions position and extent of disease spray medicine.Not only enlarged the scope of application, and manufactured simply, used very convenient.
