CS197027B1 - Sprayer for phermaceutic aerosol products - Google Patents

Description

The present invention relates to a nebulizer for pharmaceutical aerosol products for inhalation or psoral administration of pharmaceutical products.

For better application, the pharmaceutical products are in many cases manufactured in the form of a spray. In addition, the active ingredients are contained in a compressed gas container. In order to be able to apply the active substance to certain parts of the body, especially sprayers are required. Inhalation aerosols must be sprayed over the site and site of exposure, respiratory organs. The largest proportion of inhalation aerosols are those used to combat asthma attacks.

For the rapid and safe introduction of the active substance contained therein _; In these products, to the alveoli, the design of the atomiser is critical.

For the inhalation of pharmaceutical aerosols, known atomizers are rectangular and tubular, one angle arm being mounted on the core tube of the compressed gas container valve and the other arm being in use. brings to the mouth. The compressed gas container is held down by the valve in use. In one embodiment of the known atomizer, the compressed gas package is not embraced by the angle arm which is fitted to the valve. For protection against dirt, the mouthpiece tube is closable by a cap. This embodiment has the disadvantage that the stem can become stuck when the sprayer is stuck during use

19? ´ 0 27 break off the valve, leaving the system unused. This embodiment further has the disadvantage that when the atomiser is compressed, the gap between the compressed gas container and the atomiser can be closed. This leads to the avoidance of breathing and thus to incomplete inhalation.

In addition, it is not prevented when carrying the preparation with it, for example in a pocket. inadvertent activation.

In another known embodiment, one of the arms is extended as a guide sleeve and extends to the bottom of the compressed gas package. This embodiment is very expensive in terms of material and the guide sleeve must be of transparent material in order to be able to read the label of the package. The required air supply for inhalation cannot be guaranteed if the diameter of the compressed gas package deviates.

In another known embodiment, air supply openings are provided on the sprayer head. A disadvantage of this embodiment is that these holes are susceptible to contamination when the sprayer is worn.

In another known embodiment, after removing the lid from the mouthpiece tube, another inner tube must be pulled out to release the valve lock and allow the atomizer to be compressed. _w

These three-piece dispensers require increased production costs and are user-friendly. in view of the rapid preparedness for standby, which often plays a major role in the panic events of asthmatics, - very complicated.

The above drawbacks to ^t and ^t ky removes extended ^p ra ^{OVA No. P} ro ^f cal armaceu ^those výroЪky ^aerosol, comprising a rectangular tubular applicator and - closing the security part according to the invention, which is characterized -in that the closure and security part- it is formed on one side by an open, tapered cylinder with a notch and on the closed side it has an overlapping edge, the cross-section extending on the applicator and a guide sleeve having at least three equally spaced inserts arranged at the periphery.

A new and higher sprayer effect for the pharmaceutical aerosol products of the present invention is that in this embodiment, the sprayer cannot become pinched and, consequently, the valve stem cannot break. In the sprayer according to the invention, the air supply is guaranteed at every stage of use and thus the possibility of inhalation for the user.

These advantages over known sprayers - are particularly important because they guarantee safe handling, even in cases of frequently panicking users. Atomiser according ^FNA • ^ i j ^e first ^cut which sptóuje vfochny ^Z uHvatelů requirements, ^excluding o n ^t is an optimized use of material and a convenient form for the manufacturing technology.

The sprayer according to the invention is shown in the accompanying drawing, who in Fig. 1 shows a container ee with compressed gas and a sprayer, Fig. 2. closing and safety part, Fig. 3 a section through the applicator, applicator.

At rest, the closure and safety portion 2 is in the applicator 1, with the stem in the notch ⁴ and protruding on both sides of the closure and safety portion 2 against the valve carriers, thereby preventing actuation of the valve.

The applicator 1 is arranged in the atomizer system 2, comprising a nozzle-ston and storing ^e to i. The arm of the applicator 1 has an expanding cross-section to which the guide sleeve 11a is connected. the inner wall of the guide sleeve 2 J ^e ° in an insert 6, which ensure the air supply when operating the applicator 1 · For functional capacity must be at the periphery of the guide sleeve 2, at least three uniformly distributed liner 6. Thus, the guide sleeve 2 embraces the package is compressed air, no twisting is possible and the stem is secured against breakage.

The sprayer is mounted perpendicular to the compressed air (gas) container. When retracted the closure and security stem portion 2 is located in the notch 4. Using this condition is cured, 'or ^{l pl} closed och ^{y b} e ^p ez ^No. nose ^t the ^Ca with ^the 2' le ^^ ^P on both sides stem, they rest on the valve carrier.

When the closing and safety part 2 is extended, the stem stems into the atomiser system J, when the applicator 1 is depressed, the compressed gas container valve is actuated. In this case, the guide sleeve 2 embraces the casing of the compressed air package, thereby avoiding jamming. The inserts 6 arranged on the inside of the guide sleeve J ensure a constant air supply.

When using a sprayer, the applicator 1 with the unclamped arm is placed on the compressed gas or air casing 8. For inhalation, the closure and safety part 2 is pulled out.

During inhalation, the free arm of the applicator 1 is inserted into the mouth. By pressing on the surfaces of the applicator 1 located above the atomizer system 2, the contents of the pressurized gas container 8 are released and into the alveoli.
