Description

A medical nebulizer

technical field

The invention relates to the technical field of medical instruments.

Background technique

Nebulization inhalation is an important and effective way to treat respiratory diseases. It is a method of precision medicine to treat diseases. The nebulizer inhaler is used to inhale the medicinal liquid into the respiratory tract and lungs to achieve non-invasive and local treatment. , Painless, rapid and effective treatment, but also to avoid systemic complications to the greatest extent.

At present, there are two main principles of nebulizers used clinically, one is an ultrasonic nebulizer, and the other is a jet nebulizer. The jet nebulizer uses compressed air to form a nebulizer through a small nozzle according to the principle of Venturi injection. The negative pressure generated by the high-speed airflow drives the liquid to be sprayed onto the obstacle together, and splashes around under the high-speed impact, so that the liquid droplets become mist particles and are sprayed out from the outlet pipe.

However, there are three defects in the jet nebulizer currently used clinically:

First: When the patient exhales, the exhaust port of the nebulizer discharges the nebulized drug at the same time of decompressing and exhausting, which leads to the waste of the drug, the national medical insurance investment and the patient's own economic loss, and the curative effect of the patient is compromised; When inhaling drugs, there is a risk of inhaling airborne pathogens and other pollutants into the airway, resulting in cross-infection;

Second: The patient cannot control the flow rate of the inhaled drug by himself, which is inconvenient to use; for example, in the case of spitting at any time, a person cannot both spit and turn off the nebulizer in time, resulting in waste of drugs and inconvenient use;

Third: The efficiency and speed of generating nebulized drugs are not good, and the nebulization time is too long.

Contents of the invention

The present invention aims to solve the serious waste of medicines in the existing medical nebulizers. When patients inhale, there is a risk of inhaling pollutants such as pathogens in the air into the airway. To solve the problem of too long infusion time, a medical nebulizer is provided.

A medical atomizer according to the present invention, comprising an atomization cup, an atomization cup core and an atomization cover;

The bottom of the atomizing cup is provided with an air intake pipe, and one end of the air intake pipe is provided with a nozzle. The nozzle includes a nozzle body and a nozzle hole. The nozzle body is cylindrical, and the top of the nozzle body is conical. The upper part of one side of the atomization cup is provided with a suction nozzle, and the connection between the suction nozzle and the atomization cup is provided with a switch, which controls the switch of the suction nozzle and the size of the opening, and the upper part of the other side of the atomization cup There is a pressure release port, a filter membrane is set on the pressure release port, and the atomization cover is fixed on the atomization cup;

The atomization cup core includes a support part and a nozzle cover, the bottom of the support part is connected to the nozzle cover, the atomization cup core is fixed in the atomization cup, the nozzle cover is cylindrical, the top of the nozzle cover is conical, and there is a small hole at the top , the nozzle cover is tightly set on the outside of the nozzle, the inner wall of the nozzle cover is provided with a narrow groove, the narrow groove forms a gas channel, the bottom of the nozzle cover is provided with a bottom notch, one end of the narrow groove extends to the bottom notch, and the narrow groove The other end communicates with the space enclosed by the nozzle and the nozzle cover.

Compared with the existing nebulizer, the invention seals the nebulizer cup as a whole, combines the switch and the filter membrane, so that the loss of the drug during the treatment process is reduced to a very low level, and at the same time, it does not affect the normal use and does not affect the inhalation. The normal flow rate and pressure of the atomized liquid oxygen and the pressure in the atomization cup under the normal oxygen pressure flow rate when the switch is closed, the present invention will not increase the volume of the atomizer. In the medical nebulizer according to the present invention, the filter membrane can discharge the excessive pressure in the nebulizer, prevent the nebulized medicine from leaking out, prevent the pollutants in the external gas from entering, reduce the risk of cross-infection, and improve the It improves the utilization rate of drugs and greatly reduces the waste of drugs. The filter membrane is waterproof, and can be disassembled and replaced. The price is cheap, and industrial production has been realized, which will not increase the burden on patients and national medical insurance investment. The narrow groove and the bottom notch can ensure that the oxygen entering through the intake pipe will produce extremely high speed when it contacts with the liquid medicine, which improves the atomization efficiency and speed, shortens the atomization time, and is easier to be accepted by patients. There is a switch at the connection between the mouth of the suction nozzle and the atomization cup, through which the switch of the mouth of the suction nozzle and the size of the opening can be controlled to realize the free adjustment of the flow rate and flow rate of the atomized medicine, which can be operated by the patient with one hand, which is convenient for the patient to Under the premise of changing the body position, the nebulizer can be turned off at any time to save medicine; the patient can easily turn off the control switch at any time when spitting, preventing waste of medicine, easy to operate, and convenient for patients.

The nebulizer of the present invention greatly improves the utilization rate of medicine, greatly reduces the waste of medicine, avoids the waste of national medical insurance investment, saves the treatment cost of patients, reduces the economic burden of patients, and greatly improves the curative effect. For patients with chronic obstructive pulmonary disease and asthma, if calculated according to the normal usage, it is estimated that a patient can save 57.6 yuan a day, about 21,000 yuan a year, and about 210,000 yuan in ten years. The invention is easy for industrialized production, does not increase the difficulty of the manufacturing process, and is more suitable for medical application.

The invention is suitable for treating respiratory diseases.
