Embodiment Construction

[0015] From figure 1 It can be seen from the figure that a peripherally inserted central venous catheter includes a catheter 3 and a sealed needle-free infusion fluid connector 1 , and the indwelling catheter 3 is connected to the sealed needle-free fluid infusion connector 1 through a connection device 2 . The catheter is made of biocompatible materials such as silica gel, which is soft and elastic, and the catheter is also marked with scale marks. The airtight needle-free infusion fluid joint 1 and the connecting device 2 are the same as those of the prior art, and will not be repeated here.

[0016] The present invention is characterized in that: a conduit slit 5 is provided on the wall of the conduit 3 deviated from the central axis of the conduit. The distance between the catheter slit 5 and the central axis of the catheter is between 0.2-0.6 mm. Both sides of the catheter slit 5 form a large lip 6 of the catheter slit and a small lip 7 of the catheter slit. Such as ...

Abstract

The invention relates to a peripherally inserted central catheter, which comprises a catheter and a closed needle-less infusion connector, wherein the catheter is connected with the closed needle-less infusion connector by a connecting device; and a catheter cut is formed on the catheter wall at a position deviating from the central axial surface of the catheter. The catheter cut is naturally closed when the blood is not drawn back and the liquid medicament is not transfused or injected, a negative pressure is generated in a catheter cavity when the blood is drawn back by medical personnel, the large lip of the catheter cut sinks inwards; a positive pressure is generated in the catheter cavity when the liquid medicament is injected or transfused by the medical personnel, the large lip of the catheter cut bulges outwards; therefore, the catheter cut functions as a two-way catheter valve and is used as the inlet and outlet for the liquid medicament transfusion and injection and the effective opening is formed to facilitate liquid medicament injection and transfusion. The peripherally inserted central catheter has the advantages of simple structure, convenient use, good liquid controllability over the medicament transfusion and injection and capability of avoiding catheter blockage.
