Double-vena cava port capable of preventing thrombosis and preventing secondary infection

Abstract

The invention discloses a double-compartment venous port access as well as a using method of venous transfusion and drug storage sustained release thereof. The venous port access comprises an infusioncatheter and a cylindrical access body which is formed by medical silica gel, wherein the access body comprises a cavity; two ends of the access body are of hemispherical structure; the cavity is provided with a diaphragm, so that the cavity is divided into two compartments; the diaphragm is provided with pores by which liquid can permeate; and the infusion catheter is connected to one end of theaccess body and communicates with one of the compartments. The method comprises the following steps: implanting the double-compartment venous port access into a human body; penetrating an intravenousinjection into the compartment which communicates with the infusion catheter and conducting infusion; penetrating a fine-needle syringe into the other compartment of the venous port access to injectan anticoagulant or an antibacterial agent, so that the anticoagulant or the antibacterial agent is slowly released towards tissues around the compartment and / or the venous port access communicating with the infusion catheter via the diaphragm. The double-compartment venous port access is convenient for surgical implantation, and the venous port access is small in surgical incision and convenientfor puncture and infusion operations; and moreover, risks of thrombus and secondary infection can be effectively reduced.

Description

technical field [0001] The present invention relates to a device and an intravenous infusion method for intravenous infusion, in particular to a double-cavity venous infusion port implanted under the patient's skin for intravenous infusion, and to an intravenous infusion and drug storage buffer based on the intravenous infusion port. how to use it. Background technique [0002] refer to figure 1 The intravenous infusion port is a device implanted under the patient's skin for intravenous infusion. It includes a port body and an infusion catheter connected to the port body. vein, jugular vein, etc.) connected. During intravenous infusion, the intravenous infusion needle punctures into the port body, and an infusion channel is established through the port body and the infusion catheter. It is widely applicable to the input of intravenous chemotherapy drugs and nutritional liquids for malignant tumor patients, and is also used for long-term intravenous infusion for non-tumor ...

AI Technical Summary

Problems solved by technology

[0004] In further research and practice, the inventor further found that the existing venous infusion port also has the following technical defects: 1. The infusion port has been implanted in the body for a long time, and the inner cavity of the port and the implanted infusion catheter are all connected with the vein. Risk of blood clots, so regular heparin saline flushing of the access is required, causing great inconvenience to the patient

2. There is a risk of secondary infection in multiple punctures of the infusion port. In severe cases, sepsis will form and the infusion port needs to be taken out
