Abstract
The utility model discloses a medicinal upright powder valve, which comprises a fixed cover, a valve body and a valve core, wherein the fixed cover is used for being fixed on a container bottle mouth, the valve body is contained in the fixed cover, the valve core can upwards and downwards move, one end of the valve core extends out of the fixed cover by penetrating through an inner gasket, the other end thereof is abutted on the valve body through a spring, one end of the valve body is abutted with the inner gasket and clamped and fixed on the fixed cover, and a metering hole for enabling the valve core and the valve body to be continuously conducted or continuously closed through the upward and downward movement of the valve core is arranged on the valve core. When the valve is matched with a medicament container for upright use, medicament powder, particularly larger powder can be rapidly and continuously ejected, and the utility model has simple and convenient operation.
Description
Technical field
This utility model relates to a kind of doser, the powder valve that uses on especially a kind of doser.
Background technology
Medical doser has a variety of at present, the most commonly used is the doser that adopts the siphon principle design, this doser generally is that the form by hand spray is injected to medicinal liquid in patient's the oral cavity, enter patient pulmonary then, this administering mode makes the container that holds medicine produce certain negative pressure by the hand spray device, enters the oral cavity thereby make the interior medicine of container be attracted ejection.Be exactly the doser that adopts propellant pressure to spray in addition,, spray residual for a short time, therefore use more extensive because this doser atomisation pressure is big.More than these dosers generally all be the medicinal liquid that is applicable to liquid form, and for solid-state medicated powder powder in other words, how to carry out administration, the doser that industry is never good, usually all be the mode that directly adopts medicated powder to smear, one causes the medicated powder skewness easily, and the two manual medicated powder that touch form artificial pollution.
This area urgently is desirable to provide a kind of medicinal powder doser simple in structure, easy and simple to handle, in particular for the powder valve of this device.
The utility model content
In order to overcome deficiency of the prior art, this utility model provides a kind of medicinal powder valve of just putting, and this valve matches with medicament reservoir and just puts when using, and can make the ejection continuously rapidly of the especially big powder of drug powder, and is simple to operation.
The technical scheme that its technical problem that solves this utility model adopts is:
A kind of medicinal powder valve of just putting, comprise that one is used for fixing at the fixed cap on the container finish, and is installed with valve body, a spool moving up and down in fixed cap, described spool one end passes an inner washer and stretches out from fixed cap, the other end is connected on the valve body by a spring, described valve body one end butt inner washer also is fixed on the fixed cap, and described spool is provided with one and makes spool and the continuous conducting of valve body or the dip hatch of sealing continuously by moving up and down of spool.
Further, the described valve body other end connects one and leads tube cell, described valve body and describedly lead the described anti-skidding barb that tube cell comes off of leading that prevents that the tube cell coupling part is provided with a projection.
Further, described valve body is provided with one and is used to increase the side mist hole that the powder flow reduces the medicated powder obstruction, because the drug powder granule needs bigger pressure just can make the drug powder ejection, the flow that side mist hole can increase powder is set.
Further, described valve core cavity is flat lip groove structure.The purpose that the lip groove is set is to be beneficial to big medicated powder powder ejection to reduce the medicated powder deposition.
Should medicinally just put the powder valve applications promptly is tightly connected with a medicine bottle in doser mutually, medicated powder and propellant have been pre-installed in the bottle, must just put during use and use this valve, when pressing bottom spool, spool moves down, dip hatch moves to the fixed cap below, make the outlet of valve body and spool keep conducting state, the intravital medicated powder of valve sprays from the spool exit by dip hatch under the promotion of bottle internal pressure, at this moment, as long as it is motionless to pin spool, the medicated powder with in the bottle that pressure in the bottle can continue extrudes continuously, till medicated powder has sprayed in bottle, finish ejection medicated powder if desired, only need unclamp spool, spool is under the restoring force effect of spring, move up, dip hatch will move to the top of fixed cap once more like this, makes spool and valve body keep sealing state; When pressing bottom spool, once spray once more, so repeatedly.
It is just to put use that this utility model device is applied in the doser, and the effect of leading tube cell is mainly used in the medicated powder that makes in the bottle and can discharges from leading tube cell, and guaranteeing does not have medicated powder residual in the bottle substantially.
Description of drawings
Below in conjunction with drawings and Examples this utility model is further specified;
Fig. 1 is this utility model overall structure sketch map;
Fig. 2 is the cross sectional representation of this utility model spool;
The number in the figure explanation:
1. spool, 2. fixed cap, 3. valve body, 4. spring is 5. led tube cell,
6. inner washer, 7. outer washer, 8, side mist hole, 9, anti-skidding barb
10, lip groove 11. dip hatches
The specific embodiment
As Fig. 1 is this utility model overall structure sketch map; A kind of medicinal powder valve of just putting, comprise that one is used for fixing at the fixed cap on the container finish 2, and is installed with valve body 3, one spool 1 moving up and down in fixed cap 2, spool 1 one ends pass an inner washer 6 and stretch out from fixed cap 2, the other end is connected on the valve body 3 by a spring 4, valve body 3 one end butt inner washers 6 also are fixed on the fixed cap 2, and spool 1 is provided with a dip hatch 11 that makes spool 1 and valve body 3 continuous conductings or seal continuously by moving up and down of spool 1.Also sheathed one is used to keep the outer washer 7 that seals on the valve body 3, and valve body 3 other ends connect one and lead tube cell 5, valve body 3 with lead the anti-skidding barb 9 that tube cell 5 coupling parts are provided with a projection.
Valve body 1 is provided with a side mist hole 8 that is used to increase the powder flow, because the drug powder granule needs bigger pressure just can make the drug powder ejection, the flow that side mist hole 8 can increase powder is set.Spool 1 inner chamber is flat lip groove 10 structures.The purpose that lip groove 10 is set is to reduce powder deposition in spool 1 inner chamber when ejection.
Those skilled in the art will recognize that; the above-mentioned specific embodiment is exemplary; be in order to make those skilled in the art can better understand this patent content; should not be construed as is restriction to this patent protection domain; change or modify so long as disclose spiritual any being equal to of being done, all fall into this patent protection domain according to this patent.
