Above-mentioned vestibule of nose doser, preferred, described vestibule of nose doser comprises that also one removably is connected in the medicine film that described air bag is given powder, the shape of giving powder of the shape of described medicine film and described air bag is complementary.
Above-mentioned vestibule of nose doser, preferred, described medicine film is made by cotton, polyethylene or fibers material, and described medicine film is attached with viscose glue with the one side that described air bag is connected.
Above-mentioned vestibule of nose doser, preferred, described conduit is provided with a valve.
With respect to existing atomizing administration or cotton balls administering mode, this utility model vestibule of nose doser has the following advantages:
1. administration time is long, and dosage is accurate;
2. avoid coming off, easy to operate, do not influence ventilation;
3. in the clinical treatment, the scope of application is wide: by the doser of nasal membrane, can carry out pain therapy, special cancer of late stage pain therapy can also carry out the insulinize of diabetics hyperglycemia control, also can be used for the drug treatment of other diseases;
4. simple in structure, cost of manufacture is cheap, is convenient to promote the use of.
Description of drawings
By the description of its exemplary embodiment being carried out below in conjunction with accompanying drawing, the above-mentioned feature and advantage of this utility model will become apparent and understand easily.
Fig. 1 is the structural representation of this utility model vestibule of nose doser;
Fig. 2 is a center tube sketch map of the present utility model;
Fig. 3 is a medicine film sketch map of the present utility model.
The reference numeral explanation:
The 2-center tube, 4-air bag, 5-conduit, 6-valve, 7-medicine film.
The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail.
Please refer to Fig. 1, Fig. 1 is the structural representation of this utility model vestibule of nose doser.The vestibule of nose doser comprises air bag 4 and the conduit 5 that is communicated with air bag 4, and conduit 5 is used for filling gas or liquid to air bag 4.Conduit 5 is provided with a valve 6, and valve 6 is a kind of valves.Conduit 5 can be made by silica gel or plastics.
Further, the vestibule of nose doser also comprises a center tube that is used to ventilate 2, and center tube 2 runs through air bag 4.Center tube 2 comprises first terminal and second end, wherein the end face of first end and air bag 4 give powder concordant, second end stretches out outside the air bag 4, air bag 4 is fixedlyed connected with first end of center tube 2.Center tube 2 is used for nasal airflow, and one end (i.e. second end) stretches out the air bag 4 outer operations that can conveniently this device be put into nasal cavity or take out from nasal cavity.This center tube 2 can be by silica gel, vinyon or wood, bamboo work.
Air bag 4 is a hemisphere, can be by natural gum, and silica gel or fibers material are made, and have one to powder.Should circle or ellipse be arranged, central rounded vacancy to the shape of powder.This circle vacancy is used for ccontaining center tube 2.Conduit 5 is connected in the land portions of hemisphere or semiellipsoid air bag 4.
Further, the vestibule of nose doser comprises that also one removably is connected in the medicine film 7 that air bag 4 is given powder, and the shape of giving powder of the shape of medicine film 7 and air bag 4 is complementary.Please refer to Fig. 3, Fig. 3 is a medicine film sketch map of the present utility model.When air bag 4 be when annular to powder, medicine film 7 also be annular.Medicine film 7 can be made by cotton, polyethylene or fibers material, has the sexual function of extension and water absorption function.Can cover drug powder on the medicine film 7, also can the permeation liquid medicine.Medicine film 7 has medical viscose to adhere to air bag 4 contact surfaces, can be attached on the air bag 4; After the use, but the medicine film 7 on strip off air bag 4 surfaces, flusher sticks new medicine film 7 again during next administration, and device promptly can repeatedly use repeatedly.
The using method of this utility model vestibule of nose doser is as follows:
Step 1, by inlet injecting gas or the liquid of syringe from conduit 5, air bag 4 expands under the pressure effect of gas that injects or liquid.After treating air bag 4 complete expansions, the valve 6 on the closure catheter for closing 5;
Step 3 is unclamped valve 6, and gas or liquid in the air bag 4 are emitted by conduit 5, air bag 4 is narrowed down to can put into nasal cavity;
Step 4: the vestibule of nose doser is put into nasal cavity, make it touch the nose threshold, re-inject gas or liquid by the inlet of conduit 5, air bag 4 reexpands and makes the medicine film 7 that scribbles medicine be close to the nasal vestibule mucomembranous surface, the valve 6 of closure catheter for closing 5;
Step 5 after the use, has conduit 5 to emit gas or liquid in the air bag 4, and the vestibule of nose doser is taken out from nasal cavity.
In above-mentioned steps four, preferably inject warm water, purpose is the vasodilation that helps mucosa, blood flow increases to promote the abundant absorption of medicine.
Expansible air bag 4 can be fixed in the vestibule of nose, avoids coming off of device.Air bag 4 central authorities leave center tube 2, do not influence patient's ventilation.After the use, medicine film 7 can remove, and flusher changes new medicine film 7 into and covers air bag 4 surface continuation uses.This utility model vestibule of nose doser is a kind of doser of simple in structure, easy to carry, non-invasive, can be used in the treatment of nose diseases, the dispensing treatment of general disease and cancer patient's analgesia therapy.
Studies show that clinically the availability of interanasal administration can be near intravenous level, apparently higher than the availability of oral drugs; Can cardiovascular drug be arranged through the medicine that the intranasal method comes into operation, antipyretic analgesic, steroid hormone medicine, micromolecule and macromole polypeptide class medicine, antibiotic, antidiuretic and immune formulation etc.The metabolism that interanasal administration has avoided the medicine gastrointestinal to stimulate the regulating liver-QI gastrointestinal tract that medicine is passed through first, nasal mucosa is very little to the metabolism of medicine, can improve bioavailability of medicament.
It should be noted that; above content is to further describing that this utility model is done in conjunction with concrete embodiment; can not assert that the specific embodiment of the present utility model only limits to this; under above-mentioned guidance of the present utility model; those skilled in the art can carry out various improvement and distortion on the basis of the foregoing description, and these improvement or distortion drop in the protection domain of the present utility model.
