[0046] In another embodiment of this utility model, the first tee connector further includes a tee body 1011. The left and right ends of the tee body 1011 are connected to the intermediate processing pipeline and the port pipeline, respectively. A drug chamber 10111 is provided in the middle of the tee body 10111. Inside the drug chamber 10111, from top to bottom, a valve plug 1012, a valve ball 10121, a spring 10122, and a mounting strip 10123 are arranged sequentially. The valve plug 1012 and the mounting strip 10123 are fixed in the drug chamber 10111.

[0047] In this embodiment, a tee fitting with an alternative structure is provided, which can be used in working pipelines, such as... Figure 4As shown, since the internal thread 10221 of the inner wall of the valve cap 1022 is screwed to the external thread 1030, when the valve cap 1022 is rotated upward to open the upper port of the drug chamber 10111, a certain amount of drug can be added. After the valve cap 1022 is closed, the bottom end of the push rod 1013 does not contact the valve ball 10121. During the treatment process, when drug treatment is required, the valve cap 1022 is screwed downward to make the push rod 1013 move downward and squeeze the valve ball 10121 to disengage from the valve plug 1012 and compress the spring 10122, so that the drug is connected to the drug chamber 10111. At this time, the drug can enter the blood to carry out drug treatment. This design allows for real-time drug treatment during blood treatment without stopping the machine, which is safe and reliable and will not cause blood leakage problems.
