Soft catheter protection device and protection method Technical Field The invention relates to the technical field of medical instruments, in particular to a soft catheter protection device and a soft catheter protection method. Background In the clinical medical field, medical flexible catheters with precise joints at the tail ends of central venous catheters, pressure sensor connecting pipes, infusion extension pipes and the like are widely used for operations such as infusion, blood transfusion, pressure measurement, drug administration and the like. Such catheters are typically made of flexible materials, which are subject to stringent requirements for sterility, structural smoothness, and ease of use. At present, the conventional packaging mode of the medical flexible catheter with the connector is mainly in a form of directly packaging the catheter into a disposable plastic packaging pocket or a composite film bag after coiling. However, the prior packaging technology has the following defects that ① soft guide pipes are in a free and loose state in soft packaging bags, spontaneous winding and even knotting are easy to occur due to shaking and extrusion in the transportation and carrying processes, and medical staff needs to spend time to manually untwist when in clinical use, so that the standby efficiency is reduced, and the treatment opportunity is more likely to be delayed when in emergency rescue. ② The flexible package cannot provide effective radial support for the flexible catheter, when the flexible catheter is extruded by external force, the catheter is easy to generate unrecoverable dead folds or indentations, so that the inner cavity is deformed, the infusion flow rate or pressure measurement accuracy is affected, and the flexible catheter can be completely blocked when serious. ③ The delicate joint at the end of the catheter may rub, collide with other parts in the bag, and its delicate threads and sealing end surfaces are at risk of damage, thereby affecting the tightness of the connection and the safety of use. ④ After the loose bagged form is opened, the catheter is not easy to take regularly, and the structure convenient for handheld operation is lacking, so that standardized management and quick preparation in a clean working area are not facilitated. Aiming at the problems, a novel soft catheter protection device and a novel soft catheter protection method are needed to solve the problems that a catheter is easy to wind, easy to deform under pressure, easy to damage a joint, inconvenient to take and the like in the prior art.
