Description

A kind of medicinal continuous valve of just putting

Technical field

This utility model relates to a kind of doser, especially a kind of be used for using on the doser just put continuous valve.

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.

Providing multiple administering mode to the patient, is the problem that industry is studied always diligently.Common doser mainly is the aerosol spray doser at present, this doser is mainly formed by being installed with by the medicine bottle of medicinal liquid, valve and the actuator that is arranged on the medicine bottle bottleneck, valve is the important device of solution in the bottle being drawn and carrying out administration, though present various valve is a lot, develop a kind of valve simple in structure, dependable performance is the power that those skilled in the art are constantly improved raising always.

The utility model content

In order to overcome deficiency of the prior art, this utility model provides a kind of medicinal continuous valve of just putting, and this valve matches with medicament reservoir and just puts when using, and can spray continuously rapidly by medicinal liquid, and is simple in structure, easy to operate.

The technical scheme that its technical problem that solves this utility model adopts is:

A kind of medicinal continuous 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 is plugged with a catheter.

This is just being put continuous valve is applied in the doser and promptly is tightly connected mutually with a medicine bottle, medicinal liquid and propellant have been pre-installed in the bottle, just putting during use and using 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 medicinal liquid 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 medicinal liquid with in the bottle that pressure in the bottle can continue extrudes continuously, till the bottle inner liquid medicine has sprayed, finish the ejection medicinal liquid 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 catheter is mainly used in the medicinal liquid that makes in the bottle and can discharges from catheter, and guaranteeing does not have medicinal liquid 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;

The number in the figure explanation:

1. spool, 2. fixed cap, 3. valve body, 4. spring, 5. catheter,

6. inner washer, 7. outer washer, 11. dip hatches

The specific embodiment

As Fig. 1 is this utility model overall structure sketch map; A kind of medicinal continuous 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 a catheter 5.

Concerning medicinal doser, slip is to embody the important indicator of doser sealing.Slip is the important inspection item of stability experiment.Under the certain situation of identical experiment condition and container and valve system, medicine slip before the deadline is directly related with loading amount.Thereby the slip of checking medicine in stability experiment is very necessary.This just requires this valving will have strict sealing, patent device year slip be strict controlled in 1.5% with interior (national Specification annual slip is controlled in 3.5%), obviously the sealing property of patent device is better.

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.
