Abstract
A nasal cavity controlled-release dosing device is characterized in that the nasal cavity controlled-release dosing device comprises a body of a truncated-cone shape, a plurality of soft protrusions are arranged on the outer surface of the body, an air channel enabling the truncated cone to axially penetrate through is formed in the body, a plurality of liquid storage cavities are formed in the periphery of the air channel, a liquid injection port is formed in the upper portion of each liquid storage cavity, and the liquid storage cavities are communicated with the soft protrusions through mini-pipes. The problems that nose drops are short in acting time in the nasal cavity, the medicine effect cannot be completely achieved, and the medicine-applying frequency is high are solved. The nasal cavity controlled-release dosing device is ingenious in structural design, convenient to use, long in acting time, clean, environmentally friendly and the like.
Description
Technical field
This utility model relates to medical apparatus and instruments, is a kind of nasal cavity slow releasing medicine feeder specifically.
Background technology
Traditional nasal-cavity administration, because the physiological characteristics of human body nasal cavity and the action of gravity of medicine self cause all kinds of nasal drop short action time at nasal cavity, under pathological state, nasal secretion is accelerated cause medicinal liquid to be diluted and lost efficacy in addition.Above problem is perplexing medical worker for a long time, also for patient's nasal-cavity administration brings inconvenience.Short for solving nasal drop drug treating time, the drawback of simultaneously removing the frequent medicine-feeding of patient from, inventor has designed nasal cavity slow releasing medicine feeder of the present utility model.
Utility model content
The purpose of this utility model is to provide a kind of nasal cavity slow releasing medicine feeder, has solved the problems such as nasal drop is short in nasal cavity action time, drug effect cannot be brought into play completely, the number of times of adding medicine to is frequent.Its structural design is ingenious, has the advantages such as easy to use, long action time, clean environment firendly.
The purpose of this utility model is achieved in that this nasal cavity slow releasing medicine feeder, its technical essential is: comprise Frusto-conical main body, main body outer surface is provided with some soft projections, in main body, be provided with the air flue that frustum of a cone is axially connected, air flue week is upwards provided with some liquid storage cylinders, liquid storage cylinder top is provided with liquid injection port, and liquid storage cylinder is connected with soft projection by microtubule.
Described conical butt top is provided with the extension that volume is less than main body.
Described extension outer wall is provided with soft projection, and soft projection is connected with liquid storage cylinder by microtubule.
Described liquid injection port is provided with the flap valve structure that only can open to liquid storage cylinder direction.
Described nasal cavity slow releasing medicine feeder comprise two bottoms pass through in every the connected main body of snap ring.
The advantage the utlity model has and positive technique effect are: run through the axial air flue of conical butt and can not hinder normal breathing, the soft bulge-structure of body surfaces not only can be firmly spacing at nasal cavity by whole nasal cavity slow releasing medicine feeder, and soft projection is connected with the liquid storage cylinder of body interior by micro-tubular structure.When not affected by external force, micro-tubular structure can slowly be discharged into nasal mucosa by medicinal liquid by capillarity.Once and be subject to external force to push soft projection, further improved the rate of release of medicinal liquid, simultaneously the flap valve in liquid injection port is sealed in medicinal liquid in liquid storage cylinder.In sum, can make medicinal liquid evenly and lentamente discharge, and extend the time of contact of nasal mucosa and medicinal liquid, improve drug effect, without frequent drug administration, save patient's trouble, save medicinal liquid.Air barrier effect due to nasal cavity slow releasing medicine feeder, make the temperature of nasal mucosa almost identical with body temperature, accelerated the circulation of local blood, unit interval inner blood leukocyte flows through nasal mucosa sum and improves, be beneficial to all kinds of inflammatory lesions reparations, effect is more outstanding in the winter time.

Description of reference numerals: in 1 air flue, 2 soft projections, 3 main bodys, 4 liquid injection port, 5 liquid storage cylinders, 6 microtubules, 7 every snap ring, 8 extensions.
The specific embodiment
According to Fig. 1 ~ 3, describe concrete structure of the present utility model in detail.This nasal cavity slow releasing medicine feeder comprises Frusto-conical main body 3, and frustum of a cone outer wall is with certain radian, and main body 3 is made by medical silica-gel.Main body 3 outer surfaces are provided with some soft protruding 2, and soft protruding 2 contact with nasal mucosa.In main body 3, be provided with the air flue 1 that frustum of a cone is axially connected, air flue is upwards provided with some liquid storage cylinders 5 for 1 week, and liquid storage cylinder 5 tops are provided with liquid injection port 4, and liquid storage cylinder 5 is connected with soft projection by microtubule.Liquid injection port can be arranged on air flue and also can be arranged on main body outer wall.Liquid injection port 4 is provided with the flap valve structure (not shown) that only can open to liquid storage cylinder 5 directions, avoids medicinal liquid to overflow liquid injection port from liquid storage cylinder.Patient habitually Lane nose with rub nose action and contribute to medicinal liquid fully to contact with nasal mucosa.For preventing that main body is sucked, in bottom part body arranges every snap ring 7.
As shown in Figure 4, for whole nasal cavity slow releasing medicine feeder is combined more fully with nasal cavity, be provided with the extension 8 that volume is less than main body on conical butt top, extension 8 outer wall radians are less than the outer wall of main body 1.Other structures are identical with embodiment 1, not only increased the volume of liquid storage cylinder, and improved effect of heat insulation, accelerated the microcirculation effect of nasal cavity part.Liquid injection port is arranged on main body outer wall.
As shown in Figure 5, for embodiment 2, further improve, be provided with soft projection on extension outer wall, soft projection is connected with liquid storage cylinder by microtubule.Basis at embodiment 2 has further promoted curative effect of medication.Liquid injection port can be arranged on air flue and also can be arranged on main body outer wall.Liquid injection port is arranged on air flue.
