The current air pollution is becoming more and more serious, coupled with the sudden cold and hot weather during the change of seasons, resulting in an increasing number of patients with respiratory diseases. Traditional injections and medications have been difficult to meet people's needs for a high-quality life. Therefore, the safe, painless, and quick-acting atomization therapy is very popular.

At present, the atomizers in the market are divided into two types: medical atomizers and household atomizers. There are two main differences between these two types of atomizers:

1. Different object orientation

     Medical nebulizers are mostly for patients with respiratory diseases who visit a doctor, and a large number of people use them. The household atomizer is for families and is limited to family members.

2. The use effect is different

Compared with most household atomizers, the atomized particles produced by medical atomizers are fine enough to achieve a better absorption effect, thereby improving the treatment efficiency.

3. Different advantages

Household nebulizers are generally small in size, and are very convenient whether they are used at home or carried, while medical nebulizers are of higher quality and safer.

Now, in order to better help patients who need to use nebulizers to get rid of their illnesses, many brands have produced medical-grade household nebulizers, which not only have the advantage of sufficiently fine particles for medical nebulizers, but also have home nebulizers. The portability of the device. For patients suffering from rhinitis, pharyngitis, sore throat, cold, bronchitis, pneumonia, asthma, cough and other respiratory diseases, the treatment effect is better.

So, which brand of medical grade household nebulizer is better? Is the higher the brand awareness and the higher the price, the better? First of all, let's understand what is a qualified household atomizer.

1. The atomization effect is better

An atomizer with good atomization effect can play a therapeutic role. What kind of atomizer has a good atomization effect? This is determined by the size of the atomized particles. The size of the atomized particles directly determines the location of the particles in the respiratory tract, which also determines the target location of the drug. Especially for pediatric patients, the requirements for the size of the atomized particles are very high.

Let's take a picture to see where particles of different sizes can reach:

To treat tracheal inflammation, it is necessary to be able to disperse the drug-containing liquid or particles below 10 μm, and to treat the lower respiratory tract to ensure that the drug reaches the bronchi and alveoli, this requires the drug liquid or particles to be dispersed below 5 μm.

However, it should be noted that it is not that the smaller the atomized particles, the better, the particles smaller than 1μm, on the contrary, because they are too small to settle, most of the particles will be exhaled out of the lungs with exhalation. Therefore, household use can choose atomizers with particle diameters below 5μm.

2. The atomization rate can be adjusted

A qualified medical grade household atomizer, not only has a stable atomization rate, but also has the function of automatically adjusting the amount of atomization. The atomization rate can be easily adjusted according to the consistency characteristics of different drugs, or the user's own conditions, according to their own needs.

3. Low noise

    Some nebulizers are relatively loud and easily affect the mood of users, especially children. In a noisy environment, they are prone to emotions such as anxiety and restlessness, which affects the therapeutic effect. Therefore, the noise of a qualified atomizer should be less than 60 decibels.

4. Simple operation

The users of household atomizers may include the elderly and children. The operation is too troublesome and not conducive to use. When choosing, try to choose the simple operation.

5. Less drug residue

The utilization rate of the liquid medicine by a nebulizer can be seen from the amount of medicine remaining. If the liquid medicine remains too much, it proves that the utilization rate of the liquid medicine is relatively low, which will affect the effect of atomization treatment.

Based on the above factors, it can be seen that a qualified medical-grade household atomizer should have the following characteristics: small atomization particles, adjustable atomization rate, low noise, simple operation, and less drug residue. According to these hard indicators, we screened the atomizer market and found that the Lepreerui LNE502 compression atomizer and Omron NE-C28 atomizer can meet the above conditions.

But how should we choose between these two products? Let's first look at the comparison of the parameters of these two medical-grade household nebulizers:

1. Comparison of atomization speed

Experimental preparation: electronic scale, ohm-air NE-C28 atomizer, Lerui atomizer, chronograph

Note: 1) The atomizer host has been running for 10 minutes before the test;

2) Add 5ml of physiological saline to the Omron atomizer and Lerui atomizer cup respectively;

3) The mass before atomization is set to M1, the atomization time is 5 minutes, and the mass after atomization is set to M2;

4) Calculate the atomization rate V= (M1-M2)/5

By comparison, it can be seen that the Lepu Lerui LNE502 product has a speed advantage when the atomizer cup is fully closed, while the Omron NE-C28 product has a speed advantage when the atomizer cup is fully opened.

2. Comparison of atomized particles

Experimental preparation: laser particle size analyzer, ohm-air NE-C28 atomizer, Lerui atomizer

Note: 1) The atomizer host has been running for at least 10 minutes before the test;

2) The particle size analyzer starts testing after 15 minutes of preheating;

3) Add 5ml of physiological saline to the Omron atomizer and Lerui atomizer cup respectively;

4) After the atomizer is stable, start the formal measurement and collect data;

5) The amount of collected data is more than 180, and the data is averaged after collection.

It can be seen through experimental testing that the median particle size of Lepreura LNE502 is 2.576μm, all particles are below 5μm, less than 1μm (can be removed with breathing) accounted for about 1.5%, and the effective mist particles accounted for 98.5%. The median particle size of Omron NE-C28 is 2.952μm, the proportion of particles smaller than 5μm is 98%, the proportion of particles smaller than 1μm is about 1.8%, and the proportion of effective fog particles is greater than 97%.

3. Comparison of fogging noise

Experimental preparation: silent room (room), sound level meter, Ohmkong NE-C28 atomizer, Lerui atomizer, tape measure

Note:

1) The distance between the tested atomizer and the sound level meter is about 1m;

2) Test three noise data separately: empty machine running noise, atomizing cup fully closed running noise, and atomizing cup fully opened running noise;

3) The sound level meter measures the noise at the front, back, left and right sides of the atomizer 1m away from the host for verification.

Through the comparison of the atomization noise of the two products, it can be seen that the noise of the Lepu Lerui LNE502 is smaller.

Comparing the performance parameters of the two atomizer products, the advantages of the Lepu Lerui LNE502 product are mainly concentrated in the fineness of the atomization, and the overall competitiveness is stronger. For friends who want to buy a medical-grade home nebulizer, the Lepu Lerui LNE502 nebulizer is a good choice.
