[0002] The through-the-wall system provides a simple, safe and reliable solution for fluid transmission or transfer between different devices in different rooms. Compared with the solution of traditional transfer equipment, it can effectively avoid potential problems in validation, GMP management, etc. caused by cross-room transfer equipment, and at the same time avoid and reduce the risk of damage or leakage caused by traditional physical (bag or other container) liquid transfer. The safety and practicality can meet the actual needs and are widely used.
[0003] However, during the actual assembly and use of the existing through-wall system, the applicant discovered that after the two menisci assembled in the system were installed in the pipeline, if only a layer of rubber gasket was used for auxiliary sealing, the problem of air leakage at the joint between the menisci and the pipe body could not be fully avoided. Secondly, a triangular leakage point would be formed between the inner walls of the two meniscus openings and the corresponding silicone tubes in the system, further weakening the sealing effect of the overall device.
