The main material of the central venous catheter is polyurethane (PU), which has good compatibility with the human body. Single-lumen, double-lumen, three-lumen, or even four-lumen catheters can be selected according to needs. The choice of central venous catheter placement depends on the doctor's personal habits, proficiency and puncture equipment. Since there are many recent complications of catheterization, such as infection, accidental injury to the artery, pneumothorax, etc., well-trained medical personnel are required to operate it.
In recent years, the product has been continuously optimized and improved. For example, we have made super-slip treatment on the surface of the tube, which reduces the resistance of the tube and effectively prevents platelet adhesion and thrombosis. The blue soft tip of the catheter tip has strong visibility under X-rays. Easy to locate. The puncture guide wire has also been improved and applied for a patent to prevent the guide wire from being discounted and greatly improve the success rate of puncture. At present, the performance has been greatly improved. The central venous catheter can be inserted through the internal jugular vein, subclavian vein, femoral vein, etc. The central venous catheter can be used for one time and can be kept in the body for up to 30 days. If it needs to be used for a longer time, it needs to be inserted peripherally. CVC (PICC) or implantable intravenous drug delivery device (infusion port, port). The main uses of CVC in the medical industry are:
1. Measure the central venous pressure to evaluate the physiological parameters of the circulation and estimate the amount of body fluid.
2. During surgery or emergency where the blood loss may be large, CVC can be used to infuse a large amount of rapid intravenous fluids to maintain blood pressure.
3. Long-term parenteral nutrition, long-term antibiotic injection, and long-term analgesic injection.
4.Establish a good infusion channel for patients with repeated infusions to avoid the pain of repeated puncture.
5. Tubes for hemodialysis, such as plasma exchange or dialysis.
6. Tumor chemotherapy to prevent the occurrence of chemical phlebitis and prevent the extravasation of liquid medicine.
7. For more irritating drugs in peripheral veins (small veins), inject them from the central venous catheter. For example: Amiodarone and so on.
