Description

A kind of medical aerosol apparatus

Technical field

This utility model relates to medical apparatus and instruments, relates in particular to medical aerosol apparatus.

Background technology

The respiratory illness is the prevailing a kind of disease in the whole world, and medical aerosol apparatus is exactly wherein a kind of special in solving the armarium that this disease designs.

At present, medical aerosol apparatus on the market mainly contains two kinds of ultrasonic therapy aerosol apparatus and compression medical treatment aerosol apparatus, the former is made up of oscillating circuit, transducing sheet, medium tank, medicine glass and flow guide system etc., the high-frequency electrical oscillator signal is added on the transducing sheet, make it produce the high frequency mechanical shock, electric energy is converted to mechanical energy, and by the soft barrier film of medium water and medicine glass, this mechanical energy makes the medical liquid atomizing in the medicine glass.The weak point of this technology is: (1) easily produces incrustation scale because the transducing sheet is situated between directly, contacts for a long time with hydrophily, causes its permanent failure; (2) medicinal liquid in the medicine glass is under vibrating state, and when careless manipulation, medicinal liquid is splashed in the medium water easily, quickens the damage of transducing sheet; (3) be easy to generate so-called " dry combustion method " phenomenon, cause the fault rate height, service life is short.

As for compression medical treatment aerosol apparatus, mainly take the principle of compressor pump, as China Patent No. 99255639.2, name is called " medical apparatus with suction and spraying function ", Fig. 1 carries out the structural representation of spraying function for it, pressure from air pump is pressed into compressed air in the medicine glass 5 through flexible pipe 6, makes the medicine in the medicine glass 5 be pressed into interior pipe 51, again by atomizer 52 atomizing ejections.The weak point of this technology is: (1) patient is in passive status fully, can only carry out aspiratory action, the passive spray feed of accepting medicine, and the patient must every carries out active expiration at regular intervals, this breath does not have corresponding exhaust passage, influences the efficiency operation of equipment; (2) medicinal atomized particulate size, the speed of drug concentrations, ejection is difficult to be guaranteed, and these parameters are major influence factors of influence spraying Drug therapy.

Summary of the invention

At the defective of prior art, a kind of novel medical fog-spray nozzle of the special proposition of this utility model, its major technique characteristics are:

A kind of medical aerosol apparatus comprises aerochamber 1, escape pipe 2, and aerochamber 1 is made up of conduit 11 and cone 12, and conduit 11 links to each other with outside compressor, medicinal liquid; Cone 12 is a hollow structure, and its bottom and conduit 11 are communicated with, and the top is provided with atomising head, and atomising head and escape pipe 2 gas phases are logical.

In order better to reach spray effect, this utility model can also add reinforced pipe 3 between aerochamber 1 and escape pipe 2, and reinforced pipe 3 is positioned at the top of aerochamber 1, is the tubular body of a hollow, and its bottom and aerochamber 1 are communicated with, and top and escape pipe 2 gas phases are logical.

The upper lateral part of aerochamber 1 also is provided with air inlet pipe 4, and air inlet pipe 4 is the inlet port of extraneous air, and it and reinforced pipe 3 gas phases are led to, and air outside enters reinforced pipe 3 by venturi principle, can strengthen flowing of medicine mist.

In order to carry out medicine spray feed function to the patient, the physiological characteristics of simultaneous adaptation patient active expiration, this utility model is provided with medicine to sending mouth 21 and steam vent 22 at escape pipe 2 places, medicine is given an end that send mouth 21 to be positioned at escape pipe 2, and this port is the medicine spray feed end to the patient; Steam vent 22 is positioned at the other end of escape pipe 2, and and space outerpace keep to be communicated with, when patient's active expiration, the gas of being breathed out reduces the influence to medicine mist passage by steam vent 22 space outerpace of releasing; For fear of the patient when air-breathing, the influence that this steam vent 22 produces is sent mouthfuls 21 area so the area of steam vent 22 is given less than the medicine mist, also can other install when spray feed medicine mist by some, close this steam vent.

Angle from overall appearance, above-mentioned aerochamber 1, escape pipe 2, reinforced pipe 3, air inlet pipe 4 all are assembled into an integral body, and have plastics, a metal or alloy shell, and compressor, the medicinal liquid that holds medicine are in outside this integral body, medicinal liquid is pressed in the aerochamber 1 by the pressure of compressor, thereby finishes above-mentioned functions.

Owing to take abovementioned technology, the beneficial effects of the utility model are: (1) medicine is deposited on target organ with Cmax, in the shortest time, and reduces the infringement of drug side effect to health; (2) medicinal atomized granule is little, and 90% less than 5.0 μ m, has guaranteed that medicine enters the percent concentration height of bronchioles and alveolar, can effectively treat lower respiratory illness.

This utility model is widely used in hospital, the family as the armarium of treatment respiratory tract disease.
