Abstract
The utility model belongs to the technical field of medical equipment, and provides a nasal drug delivery support. The nasal drug delivery support comprises a silica gel body, wherein the surface of the silica gel body is arc. The nasal drug delivery support is characterized in that a penetrating hole is formed in the middle of the silica gel body, and a layer of absorbent cotton covers the arc surface of the silica gel body; a drug delivery tube hole is further formed in the silica gel body and is close to the arc surface of the silica gel body, one end of the drug delivery tube hole is located in the silica gel body, the other end of the drug delivery tube hole extends to the outside of the silica gel body, and a sealing plug is arranged at the open end; a plurality of drug penetrating holes are formed in the arc surface of the silica gel body and penetrate through the part, between the drug delivery tube hole and the absorbent cotton, of the silica gel body. The nasal drug delivery support is simple in structure and reasonable in design, enables drug delivery to be convenient, and makes time of the drug effect be long.
Description
Technical field
This utility model belongs to technical field of medical instruments, is specifically related to a kind of nasal-cavity administration support.
Background technology
Rhinitis and respiratory system disease are a kind of multiple diseases, have important effect by the nasal membrane medication in its treatment.And present medication therapeutic modality is mainly collunarium and spraying dual mode.When collunarium and spray delivery, medicine easily flows out in nasal cavity, causes effective drug duration short, and utilization ratio of drug is low.Simultaneously need the patient to face upward head during collunarium, cause the liquid medicine in nasal cavity to flow into patient's throat, make the patient painful hard to bear on the sense of taste.
Summary of the invention
This utility model is for the existing deficiency of prior art, and provides a kind of simple in structure, reasonable in design, and administration is easy to operate, the nasal-cavity administration support that effective drug duration is long.
For realizing above-mentioned technical purpose, the technical solution adopted in the utility model is: the nasal-cavity administration support, comprise a colloidal silica, and the surface of colloidal silica is arcuation, it is characterized in that: be provided with a through hole in the middle part of described colloidal silica, cover one deck absorbent cotton on the curved surfaces of colloidal silica; Also be provided with an administration pore in colloidal silica, it is near the curved surfaces of colloidal silica, and an end of delivery tube pore is positioned at colloidal silica, and the other end extends to the colloidal silica outside, and is provided with the shutoff plug at this opening; Be provided with several drug-filtering holes on the curved surfaces of colloidal silica, drug-filtering hole connects the colloidal silica between administration pore and absorbent cotton.
This nasal-cavity administration supporting structure is simple, reasonable in design, and is can be easily that drug injection is inner in absorbent cotton by the administration pore, can guarantee that by absorbent cotton medicine brings into play drug effect for a long time.It is smooth and easy that through hole in support can guarantee to ensure respiration in Drug therapy.
Description of drawings
Accompanying drawing is structure cutaway view of the present utility model.
In figure, 1, colloidal silica, 2, through hole, 3, absorbent cotton, 4, the administration pore, 5, the shutoff plug, 6, drug-filtering hole.
The specific embodiment
Below in conjunction with drawings and Examples, this utility model is described further.
As shown in drawings, the nasal-cavity administration support comprises a colloidal silica 1, and the surface of colloidal silica is arcuation, is provided with a through hole 2 in the middle part of colloidal silica, covers one deck absorbent cotton 3 on the curved surfaces of colloidal silica.
As shown in drawings, also be provided with an administration pore 4 in colloidal silica, it is near the curved surfaces of colloidal silica, and an end of delivery tube pore 4 is positioned at colloidal silica, and the other end extends to the colloidal silica outside, and is provided with shutoff plug 5 at this opening.
As shown in drawings, be provided with several drug-filtering holes 6 on the curved surfaces of colloidal silica, the colloidal silica that drug-filtering hole 6 connects between administration pore 4 and absorbent cotton 3.
During use, this support is close to the nasal-cavity administration face with a side of absorbent cotton sends into nasal cavity, with the opening slowly inwards injection of medicine by administration pore 4, medicine is absorbed by absorbent cotton 3 by drug-filtering hole 6, after the quantitative medicine of injection, seal the opening of administration pore 4 with shutoff plug 5, the medicines in this moment absorbent cotton 3 slowly absorb by nasal membrane, thereby reach sustained-release administration, give full play to the effect of drug effect.And normally the carrying out of can ensuring respiration of through hole 2 in support.
