Abstract

FIELD: medicine.

SUBSTANCE: method is implemented by modifying the design of a protective cap at the bottom of which safety petals are made and located in the closed state between inhaler buttons. The petals on the cap serve as stops that prevent accidental pressing of the buttons and protect the blister with the drug from premature puncture. A distinctive feature of this unit is introduction of the protective cap safety petals, which restrict buttons movement and prevent occasional premature puncture of the drug blister, to the design.

EFFECT: invention allows to improve the consumer properties of the product and increase the level of drug blister protection against premature puncture.

Description

The invention relates to devices and devices for administering drugs to the human body (inhalers).

Similar devices are:

a dry powder inhaler, suitable for delivery to the lungs or nasally, comprising an inhaler body and a capsule stand having a capsule chamber formed therein for supporting a capsule containing a drug substance; wherein the inhaler body has an opening of the inhaler body formed therein, defined between opposing upper wall and lower wall, said opening having at least one open end whereby the capsule stand can be engaged into the opening, inhalation passage which passes through the upper wall and opens into the hole in the inhaler body and the inhalation tube at the other end, and cutting means provided on the upper and lower walls [1];

- an inhaler comprising: a housing containing a medicine and a dosing system, and further comprising a mouthpiece, a lid movably attached to the body to move between an open configuration of the inhaler in which the mouthpiece is open for use and a closed configuration of the inhaler in which the mouthpiece is closed moreover, in the open position, the cover, at least partially, limits the inlet to the inhalation path of the air flow leading through the inhaler and communicating with the mouthpiece, with in the closed position, the mouthpiece is inserted into the inlet [2];

- an inhaler comprising: a body and a mouthpiece mounted on the body and having an inhalation channel, a disk-shaped assembly containing several compartments containing a drug, the disk assembly being rotatably mounted to enable sequential reduction of said compartment into a mouthpiece, wherein the mouthpiece located on the outer periphery of the disk node or beyond and communicates with the disk node through an opening in the housing, an indexing mechanism associated with the disk node, moreover, the mouthpiece is mounted with the possibility of movement relative to the housing and forms part of the indexing mechanism [3].

The prototype is an inhalation device containing a housing having a mouthpiece through which the user can inhale a dose of the drug, and a blister support element having an opening for receiving the blister containing the drug dose, the housing and the blister supporting element being rotatable relative to each other between the first position for introducing the blister into the aperture and the second puncturing position, in which the element for piercing the blister pack, moved by the housing, rokalyvaet inserted blister such that inhalation by the user through the mouthpiece dose medicament is drawn into the air stream and falls out of the blister through the mouthpiece into the patient's respiratory tract [4].

The aim of the invention is to increase the protection of the blister with the drug from premature puncture.

The purpose of the invention is achieved by introducing into the design a protective cap 1 (Fig. 1), in the lower part of which safety tabs 3 are made, located in a closed state between the buttons of the inhaler 2. The petals on the cap serve as stops (latches) that prevent accidental pressing of the buttons and protect the blister with the drug from premature puncture.

When preparing the inhaler for use, it is necessary to remove the protective cap 1 (Fig. 2), turn the mouthpiece 5, thereby freeing the opening to accommodate the blister 8 with the drug, place the blister in the opening and return the mouthpiece to its original state, close the inhaler with the protective cap until the safety caps click into place petals 3.

Before using the inhaler, it is necessary to remove the protective cap, thereby releasing the spring-loaded buttons 2. Press the buttons once, which, after puncturing the blister with needles 9, will return to their initial position under the action of return springs 10, insert the mouthpiece into the mouth, tightly compressing it with lips, and inhale through the mouth . The drug, picked up by a stream of air penetrating the inhaler through diametrically located air channels 7, will enter the human body through the inhalation channel 4. Mesh 6 prevents blister fragments from entering with the air stream.

A distinctive feature of this device is the introduction to the design of a protective cap with safety tabs that limit the movement of the buttons and prevent accidental premature puncture of the blister with the drug.

Claims (1)

An inhalation device comprising a body having a mouthpiece through which the user inhales the drug, and a blister support element with an opening for receiving the drug blister, the body and the blister support element being rotatable relative to each other between the first position for introducing the blister in the specified opening and the second position for piercing the blister pack with needles rigidly connected to the spring-loaded buttons, characterized in that the safety le of a tight protective cap is formed such in its lower portion to be placed in the closed state of the inhaler between said spring-loaded buttons for limiting their movement and prevent accidental premature puncture blisters with medicament.
