Totally implantable venous access port system puncture assisting device

Abstract

The invention discloses a totally implantable venous access port system puncture assisting device. A step through hole is formed in a fixing base; a first upper cover component comprises a first uppercover, a connecting plate and a separation mechanism; the connecting plate is connected with the lower surface of the first upper cover through a first connecting rod; a sterilization buffer paste isdetachably connected with the lower surface of the connecting plate; the separation mechanism is arranged on the first upper cover; a second upper cover component comprises a second upper cover and clamping parts which are connected in sequence; a plurality of first notches in an axial direction are formed in the clamping parts; and a plurality of guide holes are formed in the second upper cover.An injection base of a totally implantable venous access port system can be effectively positioned through a large hole in the fixing base; the first upper cover component is connected with a small hole in the fixing base; through the separation mechanism, the sterilization buffer paste can be pasted to corresponding skin above the injection base inside the large hole, and thus an injection partcan be sterilized; and the second upper cover component is connected with the small hole in the fixing base, a butterfly wing needle can accurately puncture into the injection base under guidance of the guide holes in the second upper cover component, and thus the puncture accuracy can be effectively improved.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to an auxiliary device for puncturing an infusion port. Background technique [0002] Infusion port, the full name of Totally implantable venous accessport systems (Totally implantable venous accessport systems), it is composed of an infusion catheter connected to the port body, the whole system is completely buried under the skin, and can provide long-term access to veins, arteries, abdominal cavity or The access system for spinal infusion of drugs is suitable for cancer patients with long-term chemotherapy, repeated blood draws, blood transfusions and those who need long-term intravenous nutrition. However, the existing infusion port will cause displacement in the patient's body if it exists for a long time. During the infusion process, the operator needs to hold the infusion port to fix it before puncture can be performed. The infusion port is not easy to fix, and it is n...

Problems solved by technology

However, the existing infusion port will cause displacement in the patient's body if it exists for a long time. During the infusion process, the operator needs to hold the infusion port to fix it before puncture can be performed. The infusion port is not easy to fix, and it is not convenient for puncture operation. personnel; and there is deviation in the accuracy of the puncture, repeated punctures may be required to complete the puncture; the skin on the infusion port is not easy to disinfect, and there is a risk of infection
