Abstract

The invention is related to controlling and directing blowing speed of the nebulizer which turns the liquid medicine into vapor in the form of inhalable particulates, especially in devices using mesh technology, for enabling the medicines with different densities to be taken in duration and amounts determined by the expert physician according to the patient's needs.

Description

NEBULIZER WITH DIFFERENT BLOWING SPEEDS

Technical Field

The invention is related to ensuring the nebulizer device which turns therapeutic dose of liquid medicine into an aerosol vapor in the form of respirable particles for being inhaled in a short time and reaching to the lungs, to have different blowing speeds.

More specifically, the invention is related to ensuring the medicines with different densities to be given by the treatment method and speed prescribed by the doctor depending on the needs of patients, with the device which turns liquid medicine into vapor in the form of respirable particles and which especially use mesh technology.

State of the Art

Use of medicine by nebulization is preferred at increasing rates in recent years due to its significant advantages such as local and fast effect, lower dose and less side effects as against systemic use of medicines.

Such devices allow the medicine to be given effectively to the small children, to the patients with severe asthma and to the patients to whom medicine cannot be given at a specified dose.

The nebulizer turns the liquid medicine into vapor with basically sound waves, a straining and loosening plate and compressed air and allows to be taken through inhalation.

The vibrating mesh nebulizer includes a vibratory plate that strains and loosens when electric is supplied. Such plate has approximately 1000 holes on it and aerosol medicine particles are formed by micro-injection through such holes.

Nebulizers with mesh technology turn the liquid medicine called nebul into gas form by vibrating a piezoelectric part at a certain frequency. The medicine which turned into gas form is taken by the patient through inhalation.

The dosage, density and duration of intake of such medicines varies according to course of the disease.

Densities of the Nebul medicines in the market and prescribed by doctors also vary.

With the devices using current art, blowing speed can not be changed, so depending on the density differences, some medicines affect fast and some affect slower than desired.

Such medicines are used for vital shortness of breath and respiratory system, so taking speed, amount and effecting period are of great importance.

With the devices using current art, fluid medicines with low density may be blown faster than normal and medicines with high density may be blown slower.

This case makes treatment process difficult for the physician in terms of time and amount depending on the density of current medicine and patients need to control the medicine amount required for treatment according to density of the medicine.

Medicines currently used are not blown in the same speed and this case can affect true completion of treatment process. In addition, the time required for relief of patients may be shorter or longer and patients who need to take the medicine in a lower dose and long time may unintentionally take more medicine in a short time.

Moreover, inability to control the blowing speed prevents doctors to identify patients' treatment personally.

A patient with a high degree of dyspnea may need to take the medicine faster in order to relieve as soon as possible or a patient with a low dyspnea may need to take slower. Deficiency of the existing systems is that the devices using current art operate with constant speed and it can not be set depending on the density and condition of the medicine.

In addition, the dose can not be set and this may cause consumption of more medicine, waste of medicine and may lead to additional health problems.

Considering the type of diseases, medicine diversity and the medicines to be taken fast or slowly according to course of the disease, the use of such devices for therapeutic purposes has necessitated an improvement in the blowing speed.

In addition, controlling the speed will allow proper detection of the dose and taking time. A study on implementations of the current art and the applications made on the issue has showed that no study was made for controlling the blower speed.

Considering intended use of the nebulizers, it is important to ensure the medicine to reach the lungs, in a dose and period determined by the expert physician depending on course and condition of the disease.

At this point, the invented mechanism has easy to use features that respond to the needs mentioned above and allows blowing at different and desired speeds with the speed setting button on body of the nebulizer.

Object and Brief Description of the invention

Object of the invention is to control blowing speed of the nebulizer, especially in devices using mesh technology, which allows controlling the duration of medicines with different densities that may vary from person to person depending on the course of disease.

Another object of the invention is to enable the current medicines with different densities to be blown at desired speed.

Another object of the invention is to enable physician to prepare a more flexible and special treatment process for the patients.

Another object of the invention is to prevent unnecessary consumption of medicines by providing use of medicines in the time and amount appropriate for the treatment.

Another object of the invention is to enable the dose required by the patient to reach the lungs at the optimum time and amount.

With the invention, speed of the nebulizer is controlled and current medicines can be blown at the same speed notwithstanding the density and physicians are enabled to choose treatments specific to needs of their patients.

DETAILED DESCRIPTION OF THE INVENTION

Densities of the Nebul medicines in the market and prescribed by doctors also vary

With the devices using current art, blowing speed can not be changed, so depending on the density differences, some medicines affect fast and some affect slower than desired. With the invention, speed of the nebulizer is controlled and current medicines can be blown at the same speed notwithstanding the density and physicians are enabled to choose treatments specific to needs of their patients, also unnecessary consumption of medicines is prevented by providing use of medicines in the time and amount appropriate for the treatment.

The vibrating mesh nebulizer includes a vibratory plate that strains and loosens when electric is supplied.

Such plate has approximately 1000 holes on it and aerosol medicine particles are formed by micro-injection through such holes

Mesh and Ultrasonic Nebulizers operates by vibrating a piezoelectric plate at a certain frequency.

In the invented system, frequency waves transmitted to the piezoelectric plate are controlled by an oscillator and accordingly, vibration and blowing speed of the piezo are controlled.

With the setting button on the device, the blowing speed can be set by controlling the frequency transmitted from the main power circuit to the piezo.

The vibratory plate which strains and loosens when electric is supplied and which is used in piezoelectric mesh technology has a unique resonance. The plate vibrates at maximum speed when it catches this resonance and blowing becomes the fastest.

In the invented system, resonator was added after the frequency generator and the frequency position can be set with the setting button. The blowing speed can be increased or decreased by changing the wave that reaches the plate.

The frequency transmitted from the main circuit to the piezo can be controlled by the user with a settings button.

Claims

CLAIMS - The invention is related to controlling and directing blowing speed of the nebulizer which turns the liquid medicine into vapor in the form of inhalable particulates, especially in devices using mesh technology, for enabling the medicines with different densities to be taken in duration and amounts determined by the expert physician according to the patient's needs; and its property is the oscillator placed in front of the waves sent by the frequency generator to the piezoelectric plate which forms aerosol medicine particles by micro spraying by straining and loosening with electric, another property is to allow the user to control the amount of output particles by sending waves at desired frequency from the oscillator to the piezoelectric plate, by means of the button on device.
