[0002] In intensive care units, various instruments are needed to monitor patients' vital signs. Connecting multiple instruments via a single tubing can lead to crisscrossing tubing, making connections extremely inconvenient. Furthermore, during intravenous infusions, it is sometimes necessary to administer multiple medications while simultaneously opening and closing different tubing to resuscitate the patient.

[0003] The invention patent currently published with the number CN115282462B discloses a multifunctional three-channel medical extension tube for connecting multiple tubes. It features easy operation, free control of multiple channels, and high safety performance. It solves the problem that existing three-channel tubes do not have the function of arbitrarily opening and closing one or more channels, which makes them inconvenient to use.
