As an advanced medical hyperbaric oxygen therapy device, the hyperbaric oxygen double chamber is widely used as an adjunct treatment for a variety of conditions, including brain injury, carbon monoxide poisoning, radiation-induced tissue damage, and chronic, non-healing wounds. Compared to traditional single- or multi-person chambers, the hyperbaric oxygen double chamber design balances treatment efficiency and medical safety, demonstrating significant advantages in addressing diverse patient needs and preventing cross-infection. One of its core technologies is how to achieve independent pressure regulation between the two chambers within the same device platform, while also implementing a rigorous infection prevention and control system to ensure patient safety.
1. Independent Pressure Regulation: The Technical Guarantee for Precision Treatment
A hyperbaric oxygen double chamber typically consists of two independent treatment chambers, accommodating two patients simultaneously. Although the two chambers are integrated into the same device frame, their pressure systems are designed to be physically isolated and independently controlled. Each chamber is equipped with its own independent pressure regulating valve, supply and exhaust piping, and pressure sensor, enabling independent pressurization, stabilization, and depressurization via a central control system. This means two patients can receive different treatment pressure regimens tailored to their individual medical conditions. Key to achieving this functionality lies a high-precision pressure feedback system and independent airflow design. Once compressed air or oxygen enters the device through the main air supply line, it is immediately diverted to the respective chambers to prevent cross-flow. A step-by-step control algorithm is used during pressurization and decompression, ensuring smooth pressure changes and minimizing ear discomfort for patients. Furthermore, each chamber is equipped with an independent safety valve and emergency exhaust system. If an abnormality occurs in one chamber, it can be quickly isolated and addressed independently without impacting the normal operation of the other chamber.
2. Cross-infection Prevention: Multiple Barriers Create a Safe Environment
In scenarios where multiple patients share equipment, cross-infection is a paramount concern for medical safety. The hyperbaric oxygen double chamber utilizes a four-pronged mechanism: physical isolation, independent ventilation, high-efficiency filtration, and rigorous disinfection. First, the two chambers are completely sealed and independent, with no airflow between them, fundamentally eliminating the possibility of aerosol cross-transmission. Even if two patients suffer from different infectious diseases, cross-infection from sharing equipment is prevented. Secondly, each cabin is equipped with an independent ventilation system. During treatment, fresh, multi-stage filtered compressed air is continuously introduced, and exhaust air is discharged to a designated area outside the cabin through an independent exhaust circuit. The air flow adopts a unidirectional design to avoid vortices and dead spots, ensuring uniform air refreshment within the cabin and reducing carbon dioxide accumulation and microbial concentrations. Thirdly, the air supply system integrates a high-efficiency particulate air filter and activated carbon filter, which can remove over 99.97% of 0.3-micron particles from the air, including bacteria, viruses, and allergens. Some high-end models also feature a UV sterilization module for real-time disinfection of the circulating air, further improving air quality. Finally, a rigorous disinfection process is the final line of defense in infection prevention and control. After each treatment, medical staff must wipe and disinfect the cabin surfaces using a disinfectant that meets medical standards. Some intelligent dual-cabin systems also feature ozone or hydrogen peroxide atomization disinfection, enabling unmanned, automated disinfection of the entire cabin, ensuring a safe environment for the next patient.
3. Intelligent Management: Improving Safety and Efficiency
Hyperbaric oxygen double chambers are generally equipped with an intelligent monitoring system that displays real-time parameters such as pressure, temperature, oxygen concentration, and air flow in both chambers, and provides an alarm function for abnormalities. Medical staff can remotely monitor the treatment status of both patients through a central console and intervene if necessary. The system also records data from each treatment session for traceability and quality control.
In summary, the hyperbaric oxygen double chamber, with its independent pressure regulation system and rigorous infection control design, achieves personalized treatment and safety through a "dual-use" system. It not only improves the efficient utilization of medical resources but also sets new standards in precision medicine and hospital infection control.
