Problems solved by technology

This makes it difficult to control the correct dose of the medicine you are taking because how much you take depends entirely on the strength of the airflow, and if there is too much airflow, you will ingest too much medicine at once
[0021] What's more, these devices are inevitably disposable due to the impossibility of changing the drug storage area

Embodiment Construction

[0049] According to the above description and accompanying drawings, the intranasal drug delivery device 1 according to the present invention will be described below.

[0050] It includes a shaped body 2 and a storage area 3 containing medicine suitable for inhalation by the patient.

[0051] According to an aspect of the invention, the shaped body 2 comprises a first portion 5 located at a first end 6 of the shaped body 2 . The first part 5 is shaped to protrude into the nasal cavity and includes an air delivery tube 7 which delivers air to the nostrils.

[0052] Obviously, this aspect should not be seen as limiting other different embodiments of the invention, eg the first part may comprise a plurality of air delivery tubes.

[0053] According to another aspect of the invention, the shaped body 2 also includes a second intermediate portion 9, which includes a supply tube 10, allowing air to flow into the interior of the intranasal drug delivery device 1 from the outside.

Abstract

An endonasal drug delivery device is suitable for inhalation, and comprises a shaped main body (2) having a first portion (5) located at a first end (6) of the shaped main body (2), shaped to be inserted in a nasal cavity and having an air delivery duct (7); a second intermediate portion (9) having at least one air supply duct (10) for allowing it to flow from the outside to the inside of the endonasal delivery device (1); and a third portion (12) located at the opposite end (13) of the first portion (5) and comprising a mixing chamber (14). The latter is in fluid communication with the supply duct (10), a drug reservoir (3) and the delivery duct (7).

Description

technical field [0001] The invention can be applied in the field of health, and its specific purpose is to take medicine through the respiratory tract. [0002] More specifically, the present invention relates to an intranasal drug delivery device. Background technique [0003] In the field of health, there is prior art the administration of medicinal, pharmaceutical and therapeutic substances by inhalation. [0004] Inhalation, that is, taking medicine through the respiratory tract, is usually implemented with a medicine taking device, and the medicine form includes liquid, gas or solid powder. [0005] These medication administration techniques are especially useful for treating respiratory problems. [0006] For this purpose there are known devices known as nebulizers, which generally consist of a nebuliser, ie an air compressor, which transforms the drug into a fluid carrier to reach the different organs of the respiratory system. [0007] However, the compression com...
