AI Technical Summary
Existing blood transfusion catheters are insufficient in terms of adjustment precision and anti-reflux, making it difficult to meet the needs of critically ill patients and children who have strict requirements for blood transfusion speed.
It adopts a precise flow regulation structure with a conical piston and a conical guide channel, combined with a dual anti-backflow structure of elastic valve and linkage baffle, and integrates a pressure measuring connector to achieve flow fine adjustment and anti-backflow functions.
It achieves continuous fine-tuning of blood flow rate with an accuracy of up to 0.1 ml/min, prevents blood reflux, improves transfusion safety and ease of operation, and supports real-time monitoring of central venous pressure.
