Description

Technical Field

[0001] This utility model relates to the field of medical equipment, and in particular to a water supply pipeline device for dialyzer testing. Background Technology

[0002] Hemodialysis is the primary treatment for end-stage renal disease. As a core component, the accurate measurement of the dialyzer's performance (such as clearance rate and ultrafiltration coefficient) is crucial, directly impacting patient safety and treatment efficacy. Dialyzer testing requires simulating the human hemodialysis process under specific conditions. Using test solutions conforming to standards (such as ISO 8637), the flow rate, pressure, and temperature of the test solution are precisely controlled as it flows through the blood chamber (simulating the blood side) and the dialysate chamber (simulating the dialysate side) of the dialyzer. The outflow is then collected for analysis and calculation.

[0003] Currently, common water supply methods for dialyzer testing are often fragmented and rudimentary. Testing personnel need to prepare separate water storage containers (such as large tanks or buckets) to hold the test solution, as well as separate waste collection containers. Connecting pipelines (inlet and return pipes) need to be laid manually, connecting to the water storage container, the corresponding interfaces on the dialyzer, and the waste collection container. Flow and pressure control often relies on independent external pumps, flow meters, and pressure gauges. These instruments are typically placed on a workbench or mobile cart and operated manually or with simple controllers. This existing structure has the following main problems:

[0004] 1. Low equipment integration and cumbersome operation: Water storage containers, collection containers, pumps, instruments and pipelines are scattered and occupy a lot of laboratory space. Before each test, a lot of time is spent on equipment handling, pipeline connection and disassembly, which is inefficient and prone to leakage or data error due to incorrect connection.

[0005] 2. Poor mobility and convenience: The large water tank, multiple independent devices and scattered pipelines make it difficult for the entire water supply system to be moved conveniently between different locations in the laboratory or between different testing stations as needed.

[0006] 3. Difficulty in visualization and monitoring: Operators find it difficult to intuitively and quickly observe the liquid level in the storage container and the status of the collection container.

[0007] 4. Inconvenient container replacement: When the water storage container needs to be replenished with test solution or the collection container needs to be emptied, the operation is often quite laborious.

[0008] 5. Limited control precision and automation: Dispersed equipment makes precise closed-loop control of flow and pressure and real-time data acquisition, recording and processing complicated. It relies on manual reading and adjustment, which is prone to introducing errors and makes it difficult to meet the repeatability and accuracy requirements of high-standard testing.

[0009] 6. Unfriendly human-computer interaction: Lack of a centralized and intuitive operating interface; inconvenient parameter setting, status monitoring, and process start / stop operations.

[0010] Therefore, there is an urgent need for a highly integrated, easy-to-operate, mobile, and precise automated control device for testing water supply pipelines using dialyzers, which can significantly improve testing efficiency, accuracy, and reliability, while also enhancing the operator's work experience.
