Description
Technical Field
The utility model relates to the technical field of medical instruments, in particular to a central venous catheter.
Background
The central venous catheter (Central Venous Catheter, CVC) is medical equipment for infusing medicines, nutrient solutions, blood, monitoring indexes such as central venous pressure and the like, and is widely applied to the clinical medical field. The central venous catheter is placed in the subclavian vein, the internal jugular vein or the femoral vein, and the catheter can be directly inserted into a blood vessel in the process of intubation without multiple punctures, so that pain and infection risks are reduced. Compared with other intravenous catheters, the central venous catheter can be left for a long time, monitor central venous pressure and cardiac preload, and is often used by patients who need long-time transfusion, hemodialysis or nutrition replenishment. Compared with the traditional intravenous injection, the central venous catheter is inserted into the upper venous cavity, so that a more convenient and accurate infusion process can be realized, and physiological parameters such as central venous pressure, cardiac preload and the like can be accurately monitored, thereby providing important information support for doctors. Among the central venous catheters, the central venous catheter placed on the neck is most commonly used, and has the advantages of convenience in use, less risk and less operation risk. The infusion is more suitable for long-term infusion, nutrition and medicine use. The intubation process is low in risk, can be used for a long time, and greatly reduces the risk caused by unnecessary wounds and complications.
However, the patient inevitably needs to change body position or go out of bed during the long-term placement of the central venous catheter. During these procedures, the movement of the patient tends to cause the central venous catheter to become dislodged due to external forces pulling and the like. In order to cope with this situation, it is common practice to provide a fixator at the site of implantation of the central venous catheter, to fix the central venous catheter by suturing and fixing the skin tissue around the site with the fixator by a medical suture, and to cover the central venous catheter with a medical adhesive tape as a whole. The mode mainly relies on the suture to fix, and external force traction easily leads to the damage of tissues so as to lead to the suture to deviate from, and then leads to the seepage of the embedded point, so that the adhesive tape loses viscosity, and the fixing effect is poor.
