The medical center oxygen production system, also known as the medical molecular sieve pressure swing adsorption (PSA) oxygen production system, is an oxygen production equipment that uses molecular sieves as adsorbents and ambient air as raw materials through pressure swing adsorption (PSA). Under normal temperature and low pressure conditions, it utilizes the characteristics of molecular sieves that increase the adsorption capacity of nitrogen (adsorbate) in the air when pressurized and decrease the adsorption capacity of nitrogen in the air when depressurized, forming a rapid cycle of pressurized adsorption and depressurized desorption to separate oxygen and nitrogen in the air.
VSPA medical oxygen generator making machine
The working principle of the vacuum pressure swing adsorption oxygen production system is composed of two adsorption towers containing zeolite molecular sieve adsorbents and pipeline valves. Process air enters from the bottom of one of the adsorption towers, and as it flows through the adsorbent layer, nitrogen, carbon dioxide, water vapor, and other gases in the air are adsorbed. Oxygen is collected at the top of the adsorption tower through the adsorption bed and output as product gas. At the same time, the other adsorption tower is in regeneration mode. Before the adsorption tower reaches adsorption saturation, under the intervention of the control system, the process air flows into the regenerated adsorption tower to start adsorbing and producing oxygen. Two adsorption towers alternate and take turns to achieve continuous production of oxygen.
Characteristics of VSPA Oxygen Generator
① The oxygen production host adopts PSA oxygen production technology principle, high-efficiency screw air compressor, dual adsorption tower process for oxygen production (expandable 4-8 adsorption bed and above multi adsorption bed oxygen production process), uses stainless steel material, and the adsorption tower meets the requirements of the “Safety Technical Supervision Regulations for Fixed Pressure Vessels” (TSG21-2016);
② The adsorption cycle pressure of the molecular sieve is ≥ 0.5Mpa and ≤ 0.6Mpa. The oxygen pressure does not need to be increased and can be directly supplied for clinical use through the central oxygen supply pipeline;
③ The oxygen concentration can reach 93 ± 3% (v/v) or above within 10 minutes of startup;
④ Oxygen production equipment has the highest reliability and operability of equipment operation, with good durability. Molecular sieves can achieve continuous and good operation without the need for regeneration or replacement. We adopt the patented rotary airflow technology to ensure that the molecular sieve does not pulverize, improve the efficiency of the molecular sieve, and maintain stable oxygen production and output concentration. Equipped with a dispersed air intake structure technology, the sieve hole diameter is 1.0-1.2mm, and the sieve hole spacing is 2.0-2.5mm, which can provide the service life and utilization rate of polymer sieves.
⑤ Equipped with noise reduction technology, the nitrogen emission noise can meet civilian standards; Equipped with automatic oxygen flow distribution structure technology, ensuring continuous and stable output oxygen concentration.
When the oxygen usage reaches its peak, the system will start the operation of the entire equipment to meet the oxygen demand, and automatically switch and start/stop the system status. Intelligent design, practical configuration.
When the oxygen consumption is low or at night, the system will automatically start any oxygen concentrator and switch system operation, achieving an automatic control mode of one in use and one backup, achieving the best energy-saving state.
When a single device needs maintenance or repair, the backup unit can be automatically started to ensure the normal operation of the equipment.
During a power outage, the busbar can be switched for oxygen supply to ensure the normal use of oxygen in the hospital.
Indications for medical oxygen concentrators
- High altitude sickness causes hypoxia. The characteristics of the high-altitude environment are low pressure and hypoxia. People from the plains entering the plateau generally experience stress reactions in the respiratory, circulatory, digestive, and nervous systems. Oxygen therapy with oxygen concentrators can be used for high-altitude pulmonary edema, acute mountain sickness, chronic mountain sickness, high-altitude coma, and high-altitude hypoxia caused by altitude sickness.
- Cardiovascular and cerebrovascular diseases, also known as cardiovascular and cerebrovascular diseases. Including hypertension, heart disease, coronary heart disease, myocardial infarction, cerebral thrombosis, cerebral ischemia, cerebral vertigo, atherosclerosis, etc. These diseases can cause difficulty in oxygen intake in the human body, and using an oxygen generator for oxygen therapy can timely supplement oxygen.
- Respiratory system diseases, respiratory system diseases are a common and frequently occurring disease, mainly affecting the trachea, bronchi, lungs, and chest cavity. Mild cases often include coughing, chest pain, and impaired breathing, while severe cases may have difficulty breathing and hypoxia.
- Other symptoms that require oxygen therapy, such as weak and sickly individuals with poor immunity, heatstroke, gas poisoning, drug poisoning, etc. Gas poisoning refers to using a coal stove for heating and cooking in a closed room, or using a gas water heater for prolonged bathing with poor ventilation, which can easily lead to gas poisoning accidents. After gas poisoning, people often experience dizziness, nausea, vomiting, and palpitations
