AI Technical Summary
Existing intestinal pressure relief catheters are inadequate in terms of sealing, which can easily lead to leakage of excrement, increase the difficulty of surgery and the risk of infection, and are also prone to blockage.
The design employs a synergistic approach of built-in airbags and clamping components to form a bidirectional sealing structure. Combined with the dual unblocking mechanism of external airbag reverse pressure unblocking and liquid injection flushing tube, it ensures both sealing and unobstructed flow.
It effectively prevents excrement leakage, reduces the risk of infection, reduces blockage, simplifies the operation process, reduces the risk of mucosal damage, and ensures unobstructed drainage channels.
