Portable oxygen concentrators are widely used in the medical supply industry. They are small enough to be carried and have an intelligent design, allowing their users to breathe comfortably. These devices extract oxygen from ambient air and provide it to the users through nasal cannula.
They use a sieve bed and a series of filters to separate oxygen from the nitrogen in the air. In contrast, oxygen tanks supply oxygen through pressurization. Portable oxygen concentrators are highly sought after because they are lightweight and do not require refilling.
Some portable oxygen concentrators offer continuous flow settings, while others are designed to provide oxygen in burst mode. Below is a list of some of the types of portable oxygen concentrators that buyers can invest in.
Pulse portable oxygen concentrators are excellent at detecting breathing. They have a mechanism that allows them to release oxygen when patients inhale.
The system is built with several sensors that recognize the user’s breathing pattern. When the user breathes in, the sensors notice the change in the level of carbon dioxide.
The information is sent to the pneumatic systems, which release oxygen. Users who prefer inhalation assisting oxygen therapy systems should sell oxygen concentrators in bulk to buyers.
These oxygen concentrators continuously release oxygen regardless of whether the user is inhaling or exhaling.
Many users prefer this model because it is useful for patients who require high levels of oxygen for serious health conditions.
It can also be used by buyers who want to install it in large spaces. Continuous-flow oxygen concentrators are bulky as they are large medical equipment. They are also less energy efficient and use more electricity than other models.
Many portable oxygen concentrators use pulse dosing technology, which is a more recent innovation. This device measures the user’s breathing rate and the oxygen requirements.
When the user inhales, the device releases a dose of oxygen, which is the amount required. During exhalation, it pauses oxygen release, allowing the user to breathe out without wastage. This system makes everything efficient by going with the user’s breathing pattern.
This feature is crucial for users with variable oxygen needs. People with chronic obstructive pulmonary disease (COPD), cystic fibrosis, or asthma may experience episodes where it is hard to breathe. Continuous low-flow oxygen saturation can keep them comfortable during those times.
The oxygen concentrators that wholesalers stock come in various materials. Each material offers a unique advantage. Below is a list of the various materials used in Invacare portable oxygen concentrators.
Plastics used in portable oxygen concentrators are polycarbonate, acrylonitrile-butadiene-styrene (ABS), and high-density polyethylene (HDPE). These are the most common types of plastics found in medical equipment.
ABS is chosen for its robustness and impact tolerance. On the other hand, polycarbonate is favored for its durability and heat-resistance properties.
Most portable oxygen concentrators feature metals such as aluminum and steel. The metals are used on parts that require high strength and durability, such as the casing and sieve beds. Many manufacturers choose aluminum as the primary metal because it is lighter. This factor makes the device portable.
Aluminum also resists corrosion, increasing the concentrator's lifespan and lowering maintenance costs for users. Steel, known for its sturdiness, is sometimes used in parts that require additional structural support.
Rubber is mainly used to create seals and gaskets in oxygen concentrators. The seals and gaskets are critical in maintaining the device's airtightness and preventing oxygen leaks.
These leaks compromise the device’s efficiency. The most common type of rubber used is silicone due to its capacity to withstand extreme temperatures. This capacity ensures the functionality of the seals in environments with heat variations.
Manufacturers use glass fiber to make the sieve beds that separate oxygen from nitrogen. For example, when mixed with epoxy resin, glass fiber provides the gaskets with high tensile strength and flexibility. Though a composite material, glass fiber is specifically chosen for its lightweightness.
Nitinol, a nickel-titanium alloy, is ideal for components requiring flexibility and durability. It is mostly used to make molecular sieves. The combined properties of elasticity and strength enable nitinol to maintain its structure amidst the tension found in oxygen concentration processes.
Another alloy used in this application is brass. It is primarily used in valves and fittings due to its anti-corrosive properties. They ensure that the devices maintain infrastructure integrity in humid environments.
It is important for buyers to understand the various applications of portable oxygen concentrators. Below are the diverse scenarios that wholesalers can highlight to their customers.
Portable oxygen concentrators allow patients with respiratory conditions such as COPD and sleep apnea to breathe comfortably at home.
These devices eliminate the need for bulky oxygen tanks, providing patients with a continuous and precise oxygen flow. This continuous flow enables them to move around and carry on with their daily activities while receiving the necessary medical oxygen.
EMS personnel often work in high-pressure situations where every second counts. That is why they need portable oxygen concentrators to give oxygen to patients in transit. These devices supply oxygen in emergencies where oxygen tanks are hard to find or when there is no electricity.
They are lightweight, easy to operate, and compatible with other medical equipment like ventilators and diffusion inhalers. These qualities make them fit for delivering emergency medical care.
Many concentration carriers help workers in hazardous environments such as underground mines and construction sites. They ensure workers have a steady oxygen supply surge.
This capability allows employees to safely carry out their duties in confined or low-oxygen areas and increases workplace safety standards. With these devices, companies reduce the risk of asphyxiation or other oxygen deprivation-related health problems.
Oxygen concentrators are vital for passenger safety on commercial and private flights. They ensure passengers breathe comfortably at high altitudes, where the oxygen levels are low.
Air travel has a lower atmospheric pressure. This pressure results in less oxygen available in the air, making it hard for people to breathe. Yet, the concentrators automatically adjust the oxygen concentration as the altitude changes. They are safe and easy to operate, making them fit for pilots and crew.
Portable oxygen concentrators power remote medical facilities in emergency situations such as natural disasters or conflict zones. They become critical in these scenarios as they help medical teams give the required care to patients with breathing difficulties.
These devices are light, easy to set up, and do not require regular refilling. The ease of use enables them to be deployed quickly without prior training or expertise in operating medical equipment.
Buyers often consider several factors when selecting the ideal portable oxygen concentrator for their customers. They include the oxygen flow settings, battery life, and weight of the devices.
To make an informed decision, buyers should consider the following criteria.
Different patients have varying oxygen needs. These needs determine how much oxygen flow or pulse dose the oxygen concentrator should have. Take patients with mild hypoxia, for example. They do not require high oxygen levels. They can breathe well with a low-flow continuous oxygen supply or a low pulse dose.
Conversely, those with severe hypoxia require high-flow oxygen. These patients may have difficulty breathing without assistance. They will need an oxygen concentrator with a large oxygen flow rate.
Therefore, buyers should keep this information in mind when selecting portable oxygen concentrators to sell to customers. It will ensure that the devices have the right oxygen delivery settings to match patient requirements.
It is the key advantage of oxygen concentrators over other oxygen delivery systems. Many devices are under 5 kg, with some weighing as little as 1 kg. Such ultralight equipment allows users to transport them without much hassle.
Most come with carrying cases, making them easier to transport. Some have wheels for improved mobility, which is ideal for patients with limited mobility. Buyers should also note that adjustable harness straps increase stability and user comfort. They will ensure the oxygen concentrator stays in place even when the user is in motion.
People using Invacare portable oxygen concentrators may not have prior medical knowledge. That is why it is important for buyers to prioritize those with simple interfaces when choosing these devices.
