Description

Nasal cavity drug delivery device

Technical Field

The utility model relates to the technical field of administration appliances, in particular to a nasal administration device.

Background

Nasal administration is an important effective mode for treating nasal related diseases in otolaryngological department, nasal discomfort symptoms can be quickly and effectively relieved, and nasal cavities commonly used in clinic do not need to comprise nasal drops, nasal hormones, nasal decongestants and the like.

At present, the existing nasal cavity administration device generally comprises an injection tube, a nozzle is arranged at the front end of the injection tube, liquid medicine is placed in the injection tube, the nasal cavity is placed in the nozzle in the using process, then a push rod of the injection tube is pushed, and the medicine is sprayed into the nasal cavity. The medicine is sprayed into the nasal cavity under excessive pressure, which brings discomfort to the patient; the medicine can not be tightly attached to the inner part of the nasal cavity for a long time, so that the action effect of the medicine is greatly reduced; but also the effect of cleaning the inside of the nasal cavity cannot be achieved.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects in the prior art, the utility model provides the nasal cavity administration device which can clean the surface of the nasal cavity in a large range, is tightly attached and can be used for continuous long-time administration, and the action effect of the medicine is greatly improved.

The technical scheme adopted by the utility model for solving the technical problems is as follows: the utility model provides a nasal cavity device of dosing, includes medicine bottle, stem and flexible head, the medicine bottle is the soft container of extrusion formula, the stem is hollow structure, and a plurality of through-holes have been seted up on its surface, the one end and the medicine bottle intercommunication of stem, flexible head is the porous sponge that absorbs water to the cover is established in the outside of stem.

Preferably, the flexible head is a rod-shaped structure closely attached to the inner peripheral wall of the nasal cavity.

Furthermore, a scale storage groove is formed in the surface of the flexible head.

Further, the scale storage groove is a spiral line groove.

Preferably, the medicine bottle comprises a bottle body and a bottle cap, and the bottle cap covers the bottle mouth of the bottle body.

Furthermore, the periphery of the bottle cap is provided with anti-skid lines.

Further, the stem is integrally formed with the bottle cap.

Furthermore, the medicine bottle and the core column are made of plastic materials.

Further, a protective cover is arranged outside the flexible head.

The utility model has the beneficial effects that: compared with the traditional method of adopting external spraying and spraying after insertion, the device can clean the surface of the nasal cavity in a large range, is tightly attached and continuously administers the medicine for a long time, greatly improves the effect of the medicine, and has the advantages of low cost, simple operation and use and disposable sanitary and safe use.

Detailed Description

The following further describes embodiments of the present invention with reference to the drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features involved in the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

Referring to fig. 1-4, the nasal cavity administration device of the present embodiment includes a medicine bottle 1, a stem 2 and a flexible head 3, the medicine bottle 1 is an extrusion type flexible container, the stem 2 is a hollow structure, a plurality of through holes 21 are formed on the surface of the stem 2, one end of the stem 2 is communicated with the medicine bottle 1, and the flexible head 3 is a porous water-absorbing sponge and is sleeved on the outer side of the stem 2. When the medicine bottle is used, the medicine is filled into the medicine bottle 1, the medicine is conveyed to the flexible head 3 through the core column 2 only by squeezing the medicine bottle 1, and then the medicine is slowly released through the flexible head 3.

Wherein, the flexible head 3 is a rod-shaped structure which is tightly attached to the inner peripheral wall of the nasal cavity, and the diameter of the flexible head is slightly larger than the aperture of the normal human nasal cavity; the medicine can effectively contact the inner surface of the nasal cavity, the insertion mode adopts a spiral feeding mode, the uncomfortable feeling of the insertion can be effectively relieved, and the insertion resistance is reduced. The flexible head 3 surface is seted up and is stored up dirty groove 31, and this embodiment stores up dirty groove 31 and is preferred spiral line groove, can assist flexible head 3 to insert the nasal cavity to can also possess certain clean effect of storing nasal cavity dirt.

In addition, the medicine bottle 1 comprises a bottle body 11 and a bottle cap 12, the bottle cap 12 is covered at the bottle mouth of the bottle body 11, anti-skid grains 121 are arranged on the periphery of the bottle cap 12, the bottle cap 12 and the bottle body 11 are in a screw connection mode, and the bottle cap 12 can be conveniently opened or covered through the anti-skid grains 121; the core column 2 and the bottle cap 12 can be integrally formed, and the medicine bottle 1 and the core column 2 are made of plastic materials.

Furthermore, a protective cover can be arranged outside the flexible head 3, so that the flexible head 3 inside can be protected, and the flexible head 3 is prevented from being polluted in the storage process.

Compared with the traditional method of adopting external spraying and spraying after insertion, the device can clean the surface of the nasal cavity in a large range, is tightly attached and continuously administers the medicine for a long time, greatly improves the effect of the medicine, and has the advantages of low cost, simple operation and use and disposable sanitary and safe use.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments.
