Abstract

The invention relates to an atomizer which is provided with a truncated cone chamber or two truncated cones connected through a base. Each truncated cone is formed by a series of POPOID (bendable and/or stretchable corrugation) sections, so that the chamber can keep the shape no matter in a stretching state or a contraction state in a spontaneous mode except the condition of applying internal pressure tending to expand the chamber. The atomizer is commonly used in mechanical ventilation.

Description

Nebulizer

Invention field

The present invention relates to a kind of nebulizer, it has the form that one or two truncated cone is connected to their base portion.The described truncated cone comprises sawtooth pattern and folds POPOID (flexible and/or extend ripple) and, to reduce size, make nebulizer can shrink easily or stretch, for using with the therapeutic agent of aerosol form.Described nebulizer both can be used for individual to use, and also can be used for mechanical respirator to use.

Background information

Having the nebulizer of difformity and mechanism of action commercially known is for promoting that the respiratory tract of drug administration sucks.Wherein major part is that the nebulizer change used child or adult comes.

The most famous is nebulizer, and it has two valves to prevent aerocolloidal loss in exhalation process, for be grown up and child exhale vertical full nebulizer, and English founds smooth nebulizer, and it also has valve.

Wherein the problem of partly atomized device is that they are made of plastics, and a kind ofly produces a large amount of electrostatic and attracts the material of aerosol particle; Because this reason, in Sweden, rustless steel nebulizer is created, and this is a kind of not static electrification and prevents the material of particle adhesion.The additive making its antistatic is added in some plastic chambers.

Permitted eurypalynous nebulizer and be have developed different volumes and size.Wherein many is that build is huge, is difficult to assembling, particularly when using them when client need.

There is jumbo chamber and also there is large scale, make it be difficult to transport when individual uses, the impracticable risk that there is the plastic cracking because shock or pressure cause and tear and cause.

In addition, contractile nebulizer is developed, has dissimilar structure, modal, be bellows (collapsible) or there is stiffening ring, but in use, may be complicated, because they are difficult to suitable extension, particularly when needs of patients Drug therapy.

In addition, nebulizer is being developed for ambulant patient, is combined is used for patients with mechanical ventilation with breathing circuit, rigidity, and contractile.The cylindrical tube that collapsible system is generally made up of soft material forms, and in order to make them remain on suitable state, needs to hold them.

Described POPOID (flexible and/or extend ripple) system for the adapter of tubular medical, and, more particularly, be for respiration connector, but be never used in nebulizer or have in the nebulizer of circular cone shape.

Summary of the invention

Can change drug spray to three general factors of respiratory organ is:

Granule; Main body, and inhaler.The aerial mode of particles float, the density of granule, electric charge, hygroscopicity, shape, and speed, these are all the physical characteristics of granule.Depend on that the factor of main body is: individual suction volume and inspiratory duration.Described inhaler factor be the first two mixing and to reduce mistake, nebulizer is created, and its main target promotes that the deceleration of granule is separated and sedimentation better to allow useful granule from propellant; Another advantage that nebulizer creates is to provide the evaporation of more time for propellant, it reduces the cooling effect of freon; Improve consumption especially when using adrenal cortex lipidol (producing oral candidiasis and dysphonia).

The object of this invention is to provide a kind of nebulizer, be suitable for medicine dispersion so that it arrives patient easily; Can readily be used in ambulatory patient or used by the professional person of mechanical ventilation.Except the form for providing a semi-rigid chamber to extend with it, can also automatically keep its shape.

It is equally important that when transporting nebulizer, described nebulizer varying sized and volume can take very little space.Another feature is, it is easy to dismounting and is easy to cleaning.

In a word, the invention provides a solution:

By the chamber that out-patient department and the patient of use same medicine that is connected to respiratory organ directly use.

Described chamber at contraction or extended configuration maintaining rigidness, can make it be stable, and does not need safety interlock.

Drug particle dispersion and be not attached to wall.

Suitable pharmaceutical dispersions is provided to enter chamber, so that it arrives patient easily.

Be easy to dismounting and cleaning.

Can varying sized and volume, to provide the chamber of any volume, keep chamber to be retracted to the ability of a little percentage ratio of its size simultaneously.

In the marketing, sell with folding form, and by its less size, reduce packaging and cost of transportation.

It can sterilize in the microwave oven of one family formula.

Invention summary

The present invention includes pipe or two truncateds cone connected by base portion of a circular cone shape.The described truncated cone is made up of a series of POPOID (flexible and/or extend ripple) section, make this chamber no matter can keep its shape at extended configuration or contraction state, with spontaneous form, except when applying to tend to the internal pressure expanding it.Like this device used in mechanical ventilation is exactly usually.

Nebulizer of the present invention comprises body or two truncateds cone connected by base portion that has circular cone shape, be made up of flexible material, there is multiple POPOID (flexible and/or extend ripple) folding, sawtooth pattern, its circumference forms the wall of described nebulizer with a kind of pattern of size of successively decreasing from base portion.When its each single hop of described chamber contraction meets the inside of neighbouring section all completely, namely close and take minimum space.

The pipe that this chamber stretches, the same with at contraction state, there is the characteristic that identical material more any than other or heavier material keep harder.

One in the end of the contiguous cone base portion that described nebulizer has is that the device by comprising a check valve is connected with the dissection face shield that patient uses.Be connected with the aerosol apparatus containing medicine by other device in another end of described chamber.Described nebulizer also can be used in the professional equipment of the breathing machinery with different joint.

The end of described chamber can be assembled in a different manner with securing member: bolt is connected each other, or can be connected by pressure or binding agent or be connected by such as other methods such as ultrasound wave or heat fusion.

Equally within the scope of the invention, this system allows other economic and simple versions.A kind of is fix with chamber integral type and use the card edge conntecter for MDI of identical material.Or another kind of version is, when described nebulizer has the end of integral type, it only joins check valve, belt lacing, by screw thread, assembles end by press-in connection or by the mode that ultrasound wave or heat fusion connect.

Described nebulizer has the corrugated tube truncated cone form of a folding POPOID from base portion to top (flexible and/or extend ripple).It also can be the form of two truncateds cone connected by base portion.Sawtooth pattern fold is formed by a series of POPOID (flexible and/or extend ripple) systems fold, namely, they are equal maintaining rigidness when stretching, extension and contraction state, allow mechanical ventilation to the people connecting respiratory organ, because pleating chamber allows gaseous fluid directly to pass through without amendment, directly and without change, and manage medicine in its form stretched.
