[0002] Patients in the hypocellular phase after stem cell transplantation require multiple lines of infusion, typically using multiple sequentially connected medical tees. These tees allow multiple infusion lines to be connected to the same intravenous line, eliminating the need for multiple punctures to simultaneously administer different medications.
[0003] Therefore, ensuring the secure connection between the medical tee, infusion tubing, and bed rails is extremely important. Improper fixation can cause the tee to fall off during use, contaminating and wasting the medication. Currently, medical tees are typically secured with rubber bands or medical tape, which can easily slip and fail to ensure a secure fit.
[0004] In order to ensure the stability of the medical three-way tube, fasteners can be installed on it. Chinese patent CN213628696U discloses a double-headed clamp threading clamp, including an upper clamp body and a lower clamp body, the first ends of the two are hinged, and the second ends are relatively open and closed, forming a threading clamp with two states of open and closed; it also includes a locking rod, the two ends of which are detachably connected to the second ends of the upper clamp body and the lower clamp body through a pair of elastic arms, and the outer side of the end of the elastic arm is convexly provided with a clamping point, which is embedded in the bayonet to realize the clamp connection between the elastic arm and the bayonet; when the elastic arms at both ends of the locking rod are connected to the second end clamps of the upper clamp body and the lower clamp body, the threading clamp is in a locked state and remains closed.
