Abstract
The utility model discloses a kind of drug delivery device for external auditory canal, the ontology including truncated cone-shaped, ontology lower end inner surface is equipped with the threaded portion for connecting ointment end, and ontology is made of rubber, and body outer surface is equipped with lubrication antibiotic layer.The utility model has the characteristics that simple in structure, low cost, until external auditory canal deep, convenient drug administration and using effect are good.
Description
Technical field
The utility model is related to medical aid part technology, a kind of specifically drug delivery device for external auditory canal.
Background technology
The patient of external auditory canal mould is increasing, and at present most efficient method be cleaning external auditory canal crust and mould after,
Part uses antifungal drug.And the antifungal drug locally used on the market, most of medicinal external emulsifiable paste, because of external auditory canal
Anatomy relationship, can not be effectively emulsion merging external auditory canal deep.
Utility model content
The purpose of the utility model is to overcome the shortcomings of the prior art and to provide it is a kind of it is simple in structure, make
Valency is cheap, until the good drug delivery device for external auditory canal of external auditory canal deep, convenient drug administration and using effect.
In order to achieve the above object, the utility model uses following technical scheme：A kind of drug delivery device for external auditory canal,
Ontology including truncated cone-shaped, ontology lower end inner surface are equipped with the threaded portion for connecting ointment end, and ontology is made of rubber,
Body outer surface is equipped with lubrication antibiotic layer.
The lubrication antibiotic layer is erythromycin ointment layer.
The ontology upper end diameter is 2mm, lower end diameter 8-9mm.
The body height is 20mm.
The height of the threaded portion is 5mm.
The body interior, threaded portion top are equipped with a lancet.
The utility model is had the following advantages and effect relative to the prior art：
1st, the utility model includes the ontology of truncated cone-shaped, and ontology lower end inner surface is equipped with the screw thread for connecting ointment end
Portion, ontology are made of rubber, and body outer surface is equipped with lubrication antibiotic layer, have simple in structure, low cost, until external auditory canal
The features such as deep, convenient drug administration and using effect are good.
2nd, the lubrication antibiotic layer in the utility model, protects the cleaning of external auditory canal, prevents the generation of inflammation, in addition can be suitable
Profit enters external auditory canal, convenient for administration.
3rd, the lubrication antibiotic layer in the utility model is erythromycin ointment layer, and cheap, using effect is good.
4th, the ontology upper end diameter in the utility model is 2mm；Lower end diameter is 8-9mm；Body height is 20mm；Screw thread
The height in portion is 5mm, is designed according to external auditory canal physiological property, and the in addition design of threaded portion can be suitably used for most tubulose ointment
Threaded portion mouthful.
5th, the body interior in the utility model, threaded portion top are equipped with a lancet, when attached, do not need to pierce in advance
It is broken, it is easy to use.
6th, because of external auditory canal mould, topical anti-fungal drug service life needed for 2 weeks, however can not effectively be administered, it leads
It causes therapeutic effect not good enough, if patient will obtain preferable therapeutic effect, needs frequent round-trip hospital, increase burden.This practicality is new
The structure of type, patient itself can facilitate feeds external auditory canal diseased region medicine, improves the cure rate of lesion, while joint length
Fixation, and the risk of eardrum can be avoided damage to.
Description of the drawings
Fig. 1 is a kind of structure diagram of drug delivery device for external auditory canal.
Figure label is as follows with title：
| 1 | Ontology | 2 | Threaded portion |
| 3 | Lancet |
Specific embodiment
For ease of it will be appreciated by those skilled in the art that making with reference to the accompanying drawings and embodiments to the utility model further detailed
It describes in detail bright.
Embodiment 1：
As shown in Figure 1, a kind of drug delivery device for external auditory canal, include the ontology of truncated cone-shaped, ontology lower end inner surface is set
The threaded portion of connection ointment end is useful for, ontology is made of rubber, and body outer surface is equipped with lubrication antibiotic layer.
Lubrication antibiotic layer in the present embodiment is erythromycin ointment layer；Ontology upper end diameter is 2mm；Lower end diameter is 8-
9mm.Body height is 20mm；The height of threaded portion is 5mm；Body interior, threaded portion top are equipped with a lancet；The present embodiment
In ointment be Pevisone ointment.
In actual use, the cap of Pevisone ointment is twisted off, be then screwed into threaded portion, lancet punctures ointment end
Portion makes one, then ontology is extend into external auditory canal, until eardrum and external auditory canal intersection, then squeezes and does ointment,
Drug is made directly to reach affected part, thus is avoided that drug waste, avoids tympanic membrane injury, reduces the pain of external auditory canal.
Above-mentioned specific embodiment is the preferred embodiment of the utility model, and the utility model can not be defined,
Other any changes made without departing from the technical solution of the utility model or other equivalent substitute modes, are included in
Within the scope of protection of the utility model.
