The design of the cross frame 18 not only increases the structural strength of the metal frame assembly 1, but also serves to support other components. The material of the metal frame is a medical-grade material to ensure its safety when in contact with plasma. At the same time, the design of the metal frame makes it easy to clean and disinfect, preventing plasma contamination and cross-infection;

[0033] Further, as shown in Figure 2 - Figure 4 The installation and disassembly assembly 2 comprises a through hole one 21, the through hole one 21 is formed in the side frame two 14, a through hole two 22 is formed in the inside of the side frame one 12, the outside of the bottom frame 16 is inserted into the through hole one 21 and the through hole two 22, an insertion hole 23 is formed in the inside of the top frame 11, a cross hole 24 is formed in the inside of the connecting frame 17, and the outside of the bottom frame 16 is inserted into the cross hole 24.

[0034] The through hole one 21 is arranged on the side frame two 14, which is the key position for the insertion of the bottom frame 16, so that the bottom frame 16 is connected with the side frame two 14. This connection not only provides structural stability, but also allows the bottom frame 16 to be quickly disassembled when needed. The inside of the side frame one 12 is provided with a through hole two 22 corresponding to the through hole one 21, which is used for the insertion of the bottom frame 16.
