The utility model discloses a blood return prevention monitoring device for a PICC (Peripherally Inserted Central Catheter), and belongs to the technical field of PICC. Comprising a blocking catheter, the two ends of the blocking catheter are fixedly connected with an injection connecting pipe and a catheter connecting pipe respectively, the injection connecting pipe is used for being connected with an injector, the catheter connecting pipe is used for being connected with a venous indwelling catheter, a one-way valve structure is arranged in the blocking catheter, and when blood returns to the venous indwelling catheter, reverse pressure exists in the catheter, and the blood returns to the catheter. A blocking ball is pushed by resistance of a second spring to seal an injection connecting pipe, injection one-way conduction and blood return blocking effects are formed, a piston block extrudes a first spring along an L-shaped cavity due to reverse pressure in a catheter during blood return, a push rod is forced to push a resistor block to move along a resistor disc, the actual length of the two cables electrically connected with the resistor disc is reduced, and the service life of the two cables is prolonged. The resistance monitor can monitor the blood return phenomenon of the venous indwelling catheter, and can send out a blood return alarm instruction in time to remind medical staff to deal with the blood return phenomenon in time.

The invention relates to an apparatus for closing, preferably cutting and closing, a medical tube. The invention further relates to an associated use, and to a method. An apparatus (10) for closing a medical tube (1) comprises a holding device (12) for holding a medical tube (1), a storage device (20) for storing a tube closure (7), and a closure device (22) for closing the tube (1), held in the holding device (12), by means of a tube closure (7) located in the storage device (20).

The invention relates to a closure for integration into a container. The closure has a foldable tube and a foldable tube base. The foldable tube and the foldable tube base are produced as an integral component and are designed in such a way that the foldable tube projects from the foldable tube base in a natural position and can be held by the foldable tube base in a folded position with a blocked tube channel. The invention further relates to a container for fluids, which has a foldable tube closure.

This specification provides a vent tube closure system for positioning a stopper within a syringe barrel. The system includes a vent tube insertable into the chamber of a syringe barrel, the vent tube having an internal volume configured to contain a stopper in a compressed state. The system also includes a mounting rod movable within the internal volume of the vent tube, the mounting rod being operable to push the stopper distally out of the vent tube and into the syringe barrel. The distal end of the mounting rod is provided with a shoulder and a tip extending distally from the shoulder. When pushing the stopper distally out of the vent tube, the tip engages with the bottom surface of the stopper's cavity to apply a first pressure, and the shoulder engages with the proximal surface of the stopper to apply a second pressure.
