Description

Technical Field

[0001] This utility model relates to the field of medical device design technology, specifically to a modular medical cryotherapy device housing that can be quickly disassembled and assembled. Background Technology

[0002] In the current field of medical cryotherapy equipment, the connection methods between the equipment shell and the circulation tubing have significant shortcomings. Traditional cryotherapy equipment (such as the LF-630 model) often uses fixed tubing interfaces on the shell. Connecting the circulation tubing to the shell often requires cumbersome tightening and locking operations using tools, making installation time-consuming, labor-intensive, and demanding on operator skills. Disassembly is equally difficult during equipment maintenance, cleaning, or replacement of the circulation tubing, requiring specific steps for unlocking. Slight carelessness can damage interface components, affecting the overall sealing and stability of the equipment. Furthermore, some devices, in pursuit of secure connections, excessively increase the complexity of the connection structure, resulting in bulky and heavy equipment that is inconvenient to move and store, especially in medical settings requiring frequent equipment relocation. In addition, existing connection methods struggle to balance connection stability with ease of assembly and disassembly. If quick assembly and disassembly are prioritized, connection stability is often insufficient, leading to problems such as loose tubing and leaks; conversely, if secure connections are emphasized, the assembly and disassembly process becomes complex and inefficient. Therefore, it is necessary to develop a modular medical cryotherapy device shell that can be quickly disassembled and assembled, in order to solve the problems of inconvenient disassembly and assembly of circulation tubes and shells, and the difficulty in balancing connection stability and convenience in the existing technology.
