Description

Technical Field

[0001] The utility model belongs to the technical field related to medical equipment testing, and specifically relates to an integrated detection device for a perfusion device. Background Art

[0002] In the medical field, hemoperfusion devices are an important blood purification device and are widely used in clinical treatment to remove toxins and metabolic wastes from the blood. The traditional hemoperfusion device detection process includes multiple steps such as final flushing, water injection and pressure resistance test. These steps are usually manually operated by medical staff and have high technical intensity. Not only are they inefficient, but there are also detection errors and safety hazards caused by human factors. During the disinfection process, due to the complex structure of the device, there may be uneven disinfection, resulting in the failure to completely kill microorganisms in certain parts. In order to improve the efficiency and accuracy of detection, the industry has begun to explore automated detection devices in recent years. These devices are designed to achieve automatic final flushing, water injection and pressure resistance test of the perfusion device through integrated design, thereby improving the stability and repeatability of the detection process. Despite this, the existing automated detection devices still have certain limitations, such as high equipment complexity, high cost, and inconvenient operation and maintenance. Therefore, it is necessary to develop a safe and efficient technology related to cleaning, disinfection and testing of medical equipment. Utility Model Content
