(54) SPRAYER FOR PHARMACEUTICAL AEROSOL PRODUCTS

one

This invention relates to a nebulizer used for inhalation or injecting pharmaceutical aerosol preparations into the oral cavity.

In order to provide better application, many pharmaceutical preparations are available as aerosols. In this case, the active substances are supplied in an aerosol package. To ensure that such active substances act on certain parts of the body, the use of special sprayers is required. At the place of their impact, i.e., into the respiratory organs, the inhalable aerosols should be supplied with a nebulizer inserted into the mouth. The largest proportion of inhaled aerosols is formed by those used to combat asthma attacks.

Fast and reliable supply of these drugs in the alveoli depends on the device sprayer.

Sprayers for inhalation of pharmaceutical aerosols are known in the form of a rectangular tube, one of the elbows of which is placed on the tube of the aerosol packaging and the other is inserted into the mouth when the medication is used. During the administration of the medication, the aerosol package is held in its hand with the valve down.

Sprayers are also known, in which the aerosol package does not cover, with the knee of the elbow set on BeHTHvTb. To prevent contamination on the insert $ | A cap is put on the mouthpiece. The disadvantage of this design is that in case of a disbalance of the nebulizer during the medication intake, the valve tube and, thus, the entire system can be broken. In addition, by pressing on the sprayer, the gap between the spray can and the sprayer tube can be closed. Thereby, the amount of inhaled medication is reduced and incomplete inhalation is obtained. It is also possible that the valve is triggered accidentally when, for example, the preparation is carried in a pocket of clothing.

Claims (1)

Sprayers are known in which one of the elbows is elongated in the form of a guide sleeve, which extends to the bottom of the aerosol package. Such an implementation requires a large amount of material, and the guide sleeve must be made of transparent material so that the writing on the package can be read. In case of violation of the tolerance of the diameter of the aerosol package, the air required for inhalation is not provided. A spray bottle is known, on the ridge of which air holes are provided. However, these openings are easily contaminated when the spray gun is carried in a pocket of clothing. In another known embodiment of the dispenser, after removing the cap, it is necessary to also pull out the second inner tube from the tube inserted into the mouth, as a result of which the valve is released and the dispenser can be pressed. Such a three-part nebulizer requires an increased cost of its manufacture and is too complicated for the user in terms of the necessary speed of preparation for work, which plays a big role for asthmatics who often panic when an attack occurs. The purpose of the invention is to create a nebulizer for inhalation of pharmaceutical aerosol preparations, which excludes the possibility of the valve tube breaking if the nebulizer is skewed, prevents the valve from activating arbitrarily, prevents the air supply holes from being contaminated and ensures unhindered air supply during inhalation, easy to handle , the manufacture of which is not associated with a high cost of material. The goal is achieved by the fact that the atomizer consists of a rectangular tube made in the form of an applicator and a locking-safety part, which has an open notched oblique cylinder on one side and a protruding edge on the closed side, the applicator has an extended cross-section The sleeve has at least three ribs evenly distributed around its perimeter. The sprayer is mounted vertically on the aerosol can. When the locking-safety part of the valve is pushed in, the valve tube enters the cut. The actuation of the valve in such a state is excluded, since the surfaces of the stop-safety part located on both sides of the valve tube are adjacent to the valve support. When the shut-off part of the valve tube is pulled out, it protrudes into the spray system, and when the applicator is pressed, the aerosol valve is activated. The guide sleeve at the same time covers the casing of the aerosol package, which eliminates the possibility of skewing. Due to the presence of the ribs provided on the inside of the guide bush, air is continuously supplied. FIG. G shows aerosol packaging with a spray; in fig. 2 - locking part; in fig. 3 - applicator, incision; in fig. 4 - the same, front view; in fig. 5 is a view A of FIG. 3. In the initial state, the locking part 2 is located in the applicator 1, the valve tube goes into the notch 4, and the surfaces of the locking and safety part 2 protruding from the sides support the valve support, thereby preventing accidental operation of the valve. The locking and safety part 2 closes the applicator 1 and protects it from soiling: In the applicator 1 there is a spray system 3 consisting of a nozzle and a recess for the valve tube. One of the knees of the applicator 1 has an extended cross section 5 to which the guide sleeve 7 is attached. On the inner wall of the guide sleeve 7, fins 6 are provided that provide air supply when using the applicator 1. In order to ensure the operability of the device, the inside sleeve of the guide sleeve must be There are at least three equally spaced edges 6 along it. Due to the fact that the sleeve 7 has covered the aerosol package 8, the possibility of skewing is prevented and TC kink tube. The invention The spray of pharmaceutical aerosol preparations, consisting of a rectangular, tube-shaped applicator and a locking-safety part, characterized in that the locking-safety part is an open notched open cylinder on one side, which has a protruding the edge, the applicator has an extended cross-section with a guide sleeve attached to it, and on the inner perimeter of the guide sleeve there are at least three uniformly provided On the Distribution her transverse ribs. It is recognized as an invention according to the results of the examination carried out by the Office for the Invention of the German Democratic Republic. (pue.l
