Oxygen generators (ZYA-5B, ZYA-8W, ZYA-10W)

Oxygen concentrators are machines that produce oxygen. Below is a detailed introduction to oxygen concentrators:

Working Principle

The working principle of an oxygen concentrator mainly utilizes air separation technology, separating oxygen from the air through physical or chemical methods. Specifically, there are mainly the following principles:

1. Molecular sieve adsorption separation: This is currently the most commonly used oxygen production principle on the market. Oxygen concentrators utilize the difference in adsorption performance of molecular sieves on different gas molecules to adsorb nitrogen, carbon dioxide, and other impurities in the air, while oxygen, because it is not easily adsorbed, passes through, thus achieving the separation of oxygen from impurities.

2. Electrolysis of water to produce oxygen: Oxygen is extracted by electrolyzing water, but this method requires continuous water addition and has high power consumption and a relatively short lifespan, so it is not suitable for long-term home use.

3. Oxygen-enriched membrane oxygen production: Utilizing the characteristic of high-polymer oxygen-enriched membranes that allow oxygen molecules in the air to pass through preferentially to collect oxygen, but the oxygen concentration is often not high enough, generally used for daily oxygen therapy and health maintenance.

4. Chemical reaction oxygen production: Oxygen is produced through specially formulated chemical agents in a certain proportion. This method is costly, inconvenient, and has certain dangers, making it unsuitable for home use.

Main Uses

1. Medical field: Oxygen concentrators have wide applications in the medical field, such as assisting in the treatment of pneumonia, asthma, and heart failure, providing patients with a continuous supply of oxygen to promote physical recovery. For patients with respiratory diseases, cardiovascular diseases, etc., who require oxygen therapy, oxygen concentrators can provide stable, high-concentration oxygen to improve the body's hypoxic state.

2. Home health care: In the home, oxygen concentrators can also be used for health purposes. For the elderly, pregnant women, and those engaged in high-intensity mental work, appropriate oxygen inhalation can relieve fatigue, improve immunity, and improve sleep quality.

3. High-altitude areas: The air is thin and severely oxygen-deficient in high-altitude areas. Oxygen concentrators can provide necessary oxygen supplementation for people in high-altitude areas, alleviate altitude sickness, and improve quality of life.

Types and Selection

1. Types: According to different oxygen production principles, oxygen concentrators can be divided into molecular sieve type, water electrolysis type, oxygen-enriched membrane type, and chemical reaction type. Among them, molecular sieve type oxygen concentrators are the most commonly used type on the market.

2. Selection: When choosing an oxygen concentrator, multiple factors need to be considered, including oxygen concentration, oxygen flow rate, noise level, filtration system, continuous operating time, brand, and after-sales service.

Oxygen concentration: It is recommended to choose an oxygen concentrator that meets the national standard for oxygen concentration (93% ± 3%).

Oxygen flow rate: According to the patient's oxygen demand and doctor's advice, choose a suitable oxygen flow rate. The flow rate of household health care oxygen concentrators is generally 1~2L/min, and medical oxygen concentrators are recommended to be 5L/min or more.

Noise level: To ensure patient comfort and sleep quality, it is recommended to choose a low-noise oxygen concentrator. Industry standards stipulate that the noise level of oxygen concentrators should be ≤60 decibels (dB), and below 45 decibels is more comfortable.

Filtration system: Choose an oxygen concentrator with a high-efficiency filtration system to extend the service life of the equipment and ensure that the oxygen inhaled by the patient is clean and unpolluted.

Brand and after-sales service: Choose a well-known brand of oxygen concentrator. These brands usually have stricter quality control and after-sales guarantees, providing more stable and safe products and services.

Usage and Maintenance

1. Usage:

Correctly connect the main unit, air intake filter, oxygen tube, and other components of the oxygen concentrator according to the instructions.

Insert the power cord of the oxygen concentrator into the power socket and turn on the power switch.

Add an appropriate amount of pure water to the humidifier cup to ensure that the output oxygen is moist and comfortable.

According to the usage needs, set the appropriate oxygen flow rate through the flow rate adjustment knob or button on the oxygen concentrator.

Connect the oxygen tube to the oxygen mask or nasal cannula and wear it correctly according to the instructions.

2. Maintenance:

Regularly clean and maintain the oxygen concentrator to keep the equipment dry and clean.

Avoid using the oxygen concentrator in humid or high-temperature environments.

Pay attention to the safe use of oxygen and avoid oxygen leakage causing fire hazards.
