Abstract
The utility model relates to a medicine fog suction nozzle for a medical ultrasonic atomizer, which comprises a cylindrical fog inlet joint body and a flat mouth-shaped fog sprayer body, wherein the fog inlet joint body and the fog sprayer body are integrally arranged; the fog inlet joint body is provided with a fog inlet port; the fog sprayer body is provided with a fog spray port; and medicine fog through cavities which are penetrated are arranged on the fog inlet joint body and the fog sprayer body between the fog inlet port and the fog spray port. The medicine fog suction nozzle is characterized in that an annular circular bead is arranged in the medicine fog through cavity located at the position of the fog inlet port; a fixed mount and the annular circular bead are in contact location; and valves which only can be opened unidirectionally are arranged between the fixed mount and the annular circular bead. Flowing gas exhaled from a patient is blocked by the valves so as to avoid return fog split by the patient polluting an ultrasonic atomization chamber and a corrugated catheter, so that the iatrogenic cross infection is prevented. The medicine fog suction nozzle has a reasonable design, convenience in disassembly and connection and low cost.
Description
Technical field
This practical a kind of medical inhaler, medicine mist suction nozzle of especially a kind of medical ultrasonic atomizer of relating to.
Background technology
Ultrasound atomizer is the special equipment that is used for the treatment of respiratory tract diseases such as acute pharyngitis, chronic bronchitis, its operation principle is: medicine is through forming medicinal atomized gas under the effect of ultrasonic energy in the aerochamber, then by the wind-force that produces in the nebulizer air channel, the medicine mist is by corrugated conduit and be communicated with the positions such as pharynx, larynx, trachea of sending to the patient at this supravasal medicine mist suction nozzle, to morbidity place topical, to reach excellent curative.
At present, the medicine mist suction nozzle of disclosed use one cylindricly advances the mist fittings body and a flat beak shape fog-spray nozzle body is formed by what be wholely set, advances the medicine mist cavity that mist fittings body and fog-spray nozzle body are provided with perforation.The medicine mist suction nozzle of this structure does not have prevents back the mist device, and it just plays the effect that is communicated with between corrugated conduit and the patient oral cavity.Because not having the flowing gas of being breathed out in the patient oral cavity, air force deficiency that ultrasound atomizer provides and medicine mist suction nozzle do not carry out block function, when carrying out the ultrasonic atomizatio suction, time normal adverse current of mist that the patient spues is indoor to corrugated conduit and ultrasonic atomizatio, and the danger that causes medical cross infection is arranged.Therefore, used corrugated conduit will carry out just reusing behind the soaking disinfection.But corrugated conduit often has the remaining phenomenon of air in the lowest point of its stricture of vagina paddy when soaking disinfection, has the halfway deficiency of sterilization.
Summary of the invention
Do not have and prevent back that the mist device easily causes the deficiency of medical cross infection in order to overcome prior art Chinese medicine mist suction nozzle, this utility model provides a kind of medicine mist suction nozzle, not only reasonable in design, the easy accessibility of this medicine mist suction nozzle, and can prevent effectively that the mist that returns that the patient spues from polluting corrugated conduit and ultrasonic atomizatio chamber, thoroughly eliminates medical cross infection.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of medicine mist suction nozzle, one cylindricly advance the mist fittings body and a flat beak shape fog-spray nozzle body is formed by what be wholely set, advancing to be provided with into mist port on the mist fittings body, on the fog-spray nozzle body, be provided with the spraying port, at the medicine mist cavity that is provided with perforation on mist fittings body and the fog-spray nozzle body that advances that advances between mist port and the spraying port, it is characterized in that: the medicine mist cavity of mist port is provided with an annular shoulder being positioned at into, one fixed mount contacts the location with described annular shoulder, is provided with the unidirectional only valve of opening between fixed mount and annular shoulder.
The described valve that is located between fixed mount and the annular shoulder is a bivalve formula valve, and the centre position of described fixed mount is provided with a spacing beam, and described valve is unidirectional spacing by this spacing beam.
This utility model is because the medicine mist cavity of mist port is provided with an annular shoulder being positioned at into, one fixed mount contacts the location with described annular shoulder, between fixed mount and annular shoulder, be provided with the unidirectional only valve of opening, the flowing gas that the patient breathes out is blocked by valve, the mist that returns of avoiding the patient to spue pollutes ultrasonic atomizatio chamber and corrugated conduit, has prevented medical cross infection effectively.Compared with prior art, the utlity model has advantage reasonable in design, that the company of tearing open convenient, cost is low.
Description of drawings
Below in conjunction with drawings and Examples this utility model is described in further details.
Fig. 1 is a kind of structural front view of the present utility model.
Fig. 2 is the upward view of Fig. 1.
Among the figure: 1. advance the mist fittings body, 2. the fog-spray nozzle body 3. advances the mist port, 4. spraying port, 5. medicine mist cavity, 6. annular shoulder, 7. fixed mount, 8. valve, 9. spacing beam.
The specific embodiment
In Fig. 1, a kind of medicine mist suction nozzle one cylindricly advances mist fittings body 1 and a flat beak shape fog-spray nozzle body 2 is formed by what be wholely set.
As shown in Figure 1, advancing to be provided with into mist port 3 on the mist fittings body 1.
On flat beak shape fog-spray nozzle body 2, be provided with spraying port 4.
At the medicine mist cavity 5 that is provided with perforation on mist fittings body and the fog-spray nozzle body that advances that advances between mist port 3 and the spraying port 4.
In Fig. 1, be provided with an annular shoulder 6, one fixed mounts 7 and contact the location being positioned at into the medicine mist cavity 4 at mist port 4 places with annular shoulder 6, between fixed mount 7 and annular shoulder 6, be provided with the unidirectional only valve of opening 8.
What as shown in Figure 1 and Figure 2, valve 8 adopted is bivalve formula valve.The centre position of fixed mount 7 is provided with a spacing beam 9, and the film limit of valve is unidirectional spacing by this spacing beam 9.
This utility model in use, the flowing gas of breathing out among the patient is entering the medicine mist cavity 5 of perforation, bivalve formula valve 8 contacts with spacing beam 9 with gas flow and cooperates and unidirectional closing, thereby the mist that returns of avoiding the patient to spue pollutes corrugated conduit and ultrasonic atomizatio chamber, has prevented medical cross infection effectively.
