Description
Technical field
This utility model relates to a kind of medical instruments, is specifically related to a kind of nasal cavity medicine applicator with hydrophilic lubrication function.
Background technology
The general systematic medication of whole body, not only dosage is large, and partial result is also poor simultaneously, and easily causes larger toxic and side effects.And topical not only can make up the defect of whole body administration, and can bring good curative effect.In recent years, the medication of intracoelomic cavity road has become clinical convenience and effective route of administration, as all brought into use cavitary drug feeder at aspects such as nasal cavity applied medicine, nasal cavity applied medicine and vagina medicinals, but current existing cavitary drug feeder is large with human body mucous epithelium or skin friction in the process using, easily cause the damage of cavity mucous membrane or epithelium, thereby bring very large misery to patient, and doctor uses administrator also very inconvenient.In addition,, in the time of operation administrator, owing to producing larger friction, ectogenic infection is also easily caused in the place of damage.
Utility model content
This utility model provides a kind of administrator for human body nasal cavity for above-mentioned technical problem, and the friction of this administrator and human body bronchia mucosal or epidermis is little, can greatly alleviate medication person's misery.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of nasal cavity medicine applicator, comprises conduit and dispenser head, and described conduit and/or dispenser head surface are from inside to outside successively with glue connection layer and lubricating layer; The diameter of conduit is 1～2.5cm, pipe range 2～10cm.
One side of described conduit is connected with dispenser head, and the opposite side of conduit is connected with carrier fluid container.
Longitudinal tangent plane of described dispenser head is circular arc.
The sidewall of described dispenser head is provided with 1～15 medicine-pouring hole, and medicine-pouring hole is even branch on the same longitudinal cross-section of dispenser head.
Described conduit is medical plastic pipe.
Described carrier fluid container is that bolt is connected with conduit.
Glue connection layer described in the utility model is γ-glycidyl ether oxygen propyl trimethoxy silicane (γ-MPS) layer, gamma-methyl allyl acyloxypropyl trimethoxysilane (γ-GPS) layer, 3-aminopropyl trimethoxysilane (3-APS) layer, TMSDEA (TMSDEA) layer or tertiary butyl dimethylchlorosilane (TBDMCS) layer.
Lubricating layer described in the utility model is polyvinylpyrrolidone layer, β-(1 → 4)-2-amino-2-deoxy-D-Glucose layer, hyaluronate sodium layer, ethyl cellulose layer or hydroxypropyl emthylcellulose layer.
The beneficial effects of the utility model
The technical solution of the utility model, the lubricating layer that adopts water soluble polymer lubriation material to form, what after chance water, can become is extremely lubricated, greatly reduces friction and the damage of administrator conduit and body cavity mucosa or epidermis, reduces medication person's misery in use.For doctor, easy operating, reduces the operating time, without using the lubricants such as paraffin, little to the zest of human body nasal cavity part.Nasal cavity medicine applicator also has advantages of simple in structure, easy to use, easy to carry simultaneously.
