[0002] We call this type of patients critically ill patients if their vital signs are unstable, their condition changes rapidly, and the functions of more than two organ systems are unstable, and the decline or failure of the condition may endanger their lives. In clinical practice, due to the critical condition of critically ill patients, multiple intravenous routes need to be infused simultaneously. The existing infusion method is generally to connect multiple three-way valves in sequence, which is not only cumbersome to operate and increase the workload of medical staff, but also because there are many connections, the connections are prone to leakage. Therefore, we have launched a new three-way assembly for critically ill patients. Utility Model Content
