Central venous catheter (CVC) puncture system and use method thereof

Abstract

The invention discloses a central venous catheter (CVC) puncture system and a use method thereof, and is used for solving the problem that the traditional ascites puncture methods cause heavy workload, high expenses and high abdominal infection probability. The system is mainly formed by a CVC puncture needle, a dilator and a catheter, wherein the CVC puncture needle is used for forming a puncture hole; the dilator is used for dilating the puncture hole; and the catheter is inserted into the puncture hole. The use method mainly comprises the following steps: (1) inserting the CVC puncture needle from a puncture point to form the puncture hole and leading a guide wire into the puncture hole along the CVC puncture needle; (2) taking out the CVC puncture needle; (3) inserting the dilator into the puncture hole along the guide wire and dilating the puncture hole with the dilator; and (4) taking out the dilator and putting the catheter end of a CVC into the puncture hole. The system avoids the problem of ascites exosmosis and has the advantages that the medical expenses are saved and the patient pains are relieved.

Description

technical field [0001] The invention relates to a puncture system, specifically a central venous catheter puncture system; the invention also relates to a method for using the abdominal cavity puncture system. Background technique [0002] Ovarian hyperstimulation syndrome (OHSS) is a common complication of IVF, mainly manifested as ovarian enlargement and the formation of a large amount of ascites, often requiring drainage of ascites to reduce the pressure of ascites on the heart, lungs, kidneys and other important organs . However, traditional ascites drainage uses a puncture needle for one-time puncture. When the puncture needle is used for ascites drainage, it often causes extravasation of ascites, and sometimes causes high edema in the perineum and thighs. And often in the whole process of hydroperitoneum, it is necessary to repeatedly use traditional puncture needles for multiple puncture and drainage. chance of infection.
