Description

Technical Field

[0001] This application relates to the field of medical devices, and in particular to a multi-channel infusion adapter. Background Technology

[0002] Currently, clinically available three-way connectors can only connect a maximum of two infusion lines. However, many patients sometimes require multiple infusion lines, necessitating the continuous connection of multiple three-way connectors. Each additional connector not only increases the risk of infection in the intravenous catheter but also makes it easy for adjacent connectors to detach, resulting in medication not being delivered into the patient's vein and blood flowing out of the body through the three-way connector, affecting the quality of treatment and increasing the risk to the patient. Utility Model Content

[0017] In one possible implementation, the first sealing element includes a connecting plate fixed on the rotating shaft and located inside the second connecting pipe, and a sealing ring disposed on the outer wall of the connecting plate. The first connecting plate is spherical.

[0018] In one possible implementation, the second sealing element is a rectangular plate.

[0019] In one possible implementation, the infusion tubing connector has threads.

[0020] In one possible implementation, an elastic cloth strip is provided on the outer wall of the tube, and a transparent cover is fixedly provided on the outer wall of the tube at the corresponding positions of the multiple second connecting tubes.
