Cognitive Misunderstandings: Three Major Purchasing Traps of Medical Oxygen Generators
1. "The Lower the Price, the Better": A Hidden Trap of High Costs
Low - priced medical oxygen Generators may seem to save the budget, but they actually hide hidden dangers. Such equipment usually uses inferior molecular sieves (with a service life of less than 15,000 hours) and unstable oxygen concentration technology (with fluctuations of more than ± 5%), leading to the following problems:
- Impaired treatment effect: Large fluctuations in oxygen concentration (＞± 3%) will directly affect the effect of oxygen therapy for patients, especially those with chronic obstructive pulmonary disease who need high - concentration and stable oxygen supply.
- The short service life of molecular sieves means more frequent replacements, with each replacement costing about 1,000 - 2,000 yuan. In the long run, it will be more expensive to use.
- Inferior equipment may lack necessary safety protection functions, increasing the risk of medical accidents.
Real case: After a top - three hospital in Sichuan purchased a low - priced oxygen generator, the oxygen concentration became unstable after only 12,000 hours of use, resulting in poor treatment effects for 3 patients. Finally, the hospital was forced to replace the equipment in advance, and the total cost was 40% higher than the original budget.
2. "The Larger the Flow Rate, the Better": Waste of Resources Due to Over - configuration
Blindly pursuing high flow rates is a common purchasing misunderstanding in medical institutions. In fact, it should be accurately matched according to the needs of the department:
- ICU: It really needs a high flow rate of at least 5 - 10L/min, but not all departments need it.
- General wards: 1 - 3L/min can meet the needs. Purchasing too large models will cause a waste of resources.
- Hospitals in plateau areas: Altitude compensation should be considered. The actual oxygen supply capacity of each model will decrease in high - altitude areas, so models with pressure compensation technology should be selected.
If a 5L oxygen generator is used in a general ward and only needs a 3L flow rate per day, the loss rate of its molecular sieve is 30% faster than that when used in the ICU, which means that the core components need to be replaced earlier, increasing maintenance costs.
3. "Ignoring Noise Control": Affecting Medical Work and Patients' Rest
Noise is a key indicator that is easily ignored in the purchase of medical equipment. Excessive noise not only affects the experience of doctors and patients, but also may violate industry regulations. According to the "General Technical Specification for Medical Molecular Sieve Oxygen - generating Equipment", the operating noise of medical molecular sieve oxygen - generating equipment shall not exceed 85 decibels (equivalent to the sound level of a noisy street) to ensure the comfort and safety of the medical environment. Equipment exceeding this standard will face the risk of being out of service.
- Impact of noise: Noise exceeding 85 - 90 decibels is equivalent to the sound level of a noisy street. Long - term exposure will lead to a significant decrease in the work efficiency of medical staff, damage to patients' sleep quality, and a significant increase in anxiety.
- Patient experience: Long - term exposure to a high - noise environment leads to a decrease in the communication efficiency of medical staff and a 35% decrease in patients' satisfaction with treatment.
- Equipment life: High noise is usually accompanied by poor heat dissipation, which increases the risk of overheating of the compressor and shortens the service life of the equipment.
A secondary hospital in Hunan was required to rectify by the health supervision department because it purchased equipment with a noise level of 90 decibels, and the department's rating was affected due to patient complaints.
Core Indicators: Four Key Parameters for Purchasing
1. Oxygen Concentration Stability
Medical oxygen Generators must ensure that the oxygen concentration is stable at 93% ± 3%, which is the guarantee of medical effect.
- Technical guarantee: High - quality oxygen Generators adopt a medical gas alarm system to ensure accurate and stable oxygen concentration.
- Verification method: When purchasing, suppliers should be required to provide third - party test reports to verify the stability of oxygen concentration.
- Purchasing points: Be alert to merchants who use "maximum oxygen concentration" to pretend to be "standard oxygen concentration". Pay attention to the stability of the equipment's oxygen concentration after 24 hours of continuous work.
2. Molecular Sieve Life
It is the key to long - term use cost. The molecular sieve is the core component of the oxygen generator, and its service life directly affects the use cost and reliability of the equipment.
- High - quality standard: The service life of imported sodium - type molecular sieves can reach 18,000 - 20,000 hours, which is equivalent to stable operation for 6.8 years when used for 8 hours a day.
- Life calculation: Molecular sieve life = total working time / (daily use time × 365 days).
- Maintenance cost: The replacement cost of molecular sieves accounts for about 30% - 40% of the total equipment price. The shorter the service life, the higher the replacement frequency.
The service life of high - quality domestic molecular sieves is about 12,000 - 15,000 hours, and that of imported sodium - type molecular sieves can reach 18,000 - 20,000 hours. The medical molecular sieve oxygen generator of Yite Medical can be guaranteed for ten years. The difference in service life directly leads to a difference of about 20% - 30% in use cost.
3. Intelligent Monitoring Function
It is the guarantee for safe operation. Modern medical oxygen Generators should be equipped with a complete intelligent monitoring system to ensure safe operation and centralized management.
- Essential functions: Oxygen moisture content alarm, oxygen concentration alarm, power failure alarm, automatic shutdown when tilted, etc.
- Advanced functions: Remote data transmission, fault self - diagnosis, use timing record, full data collection of the working status of hospital gas, loss control, zoned metering, etc.
- Safety value: The intelligent monitoring system can early warn of equipment failures, avoiding treatment interruptions or safety problems caused by abnormal equipment.
Oxygen Generators with intelligent monitoring systems have an average 40% reduction in failure rate and an extension of more than 25% in equipment service life. Yite Medical's medical molecular sieve oxygen generator has the most complete qualifications in the industry and also has the industry - exclusive compressed air dew point monitor, which maximizes the safety of gas use.
4. Plateau Adaptability
It is an essential capability for special environments. For hospitals in plateau areas with an altitude of more than 3,000 meters, oxygen Generators must have pressure compensation technology.
- Technical principle: Compensate for the decrease in oxygen concentration in a low - pressure environment by adjusting the working pressure of the compressor and the adsorption time of the molecular sieve.
- Performance index: High - quality plateau models can still maintain an oxygen concentration of more than 90% at an altitude of 5,000 meters.
- Environmental adaptation: Plateau models usually have more powerful heat dissipation systems and low - temperature resistant designs.
Industry case: A hospital in a plateau area purchased an oxygen generator without pressure compensation technology. At an altitude of 5,000 meters, the oxygen concentration dropped to 85%, which could not meet the treatment needs of patients, and finally had to replace the equipment. Yite Medical has a complete range of oxygen generator models to meet the needs of medical institutions at all levels.
The purchase and use of medical oxygen Generators is a highly professional work. Medical institutions should establish a scientific equipment management process to ensure that oxygen Generators can provide high - quality oxygen therapy services for patients stably for a long time and truly become reliable equipment to protect patients' lives.
