Indwelling arteria femoralis puncture sheath and application thereof

Abstract

The invention relates to an indwelling arteria femoralis puncture sheath and application thereof. The indwelling arteria femoralis puncture sheath comprises a sheathing canal, a silica gel valve base and a protective bag. The sheathing canal is a hollow hose. One end of the sheathing canal is fixed to the silica gel valve base. The other end of the silica gel valve base is connected with the protective bag. A connecting sleeve is arranged at the joint of the sheathing canal and the silica gel valve base. A silica gel valve is arranged at one end of the silica gel valve base. A fixing wing is further arranged in the middle of the connecting sleeve. The fixing wing and the connecting sleeve are integrally formed at a time. The indwelling arteria femoralis puncture sheath further comprises a guide tube, a guide wire and a trocar. The indwelling arteria femoralis puncture sheath has the advantages that the indwelling arteria femoralis puncture sheath is placed into the body when used for the first time, disengagement and pollution can be prevented, and repeated operation can be performed on the artery blood vessel conveniently when endovascular treatment research is performed in the follow-up process; a protective bag is selected to be placed under the skin, positioning is convenient, and medicine is injected; a silica gel valve is selected, can be connected to a treatment tool external and is good in internal sealing performance.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an indwelling femoral artery puncture sheath and its application. Background technique [0002] The femoral artery is the main trunk of the arteries of the lower extremities and continues from the external iliac artery. Deep into the femoral triangle at the midpoint of the inguinal ligament. In the femoral triangle, the femoral artery is first located on the outside of the femoral vein, gradually crosses from the outside to the front of the femoral vein, descends into the adductor canal, and then penetrates the abductor tendon hiatus to the popliteal fossa, and is renamed the popliteal artery. The femoral artery is superficial at the midpoint of the groin, and the pulse can be felt. It is the site for first aid compression and hemostasis and puncture in clinical practice. [0003] In recent years, vascular interventional therapy has developed rapidly, and vascular t...

Problems solved by technology

[0006] The above solution solves a technical problem of real-time quantitative monitoring of arterial pressure. However, there is no protective device between the blood vessel and the outside world during the operation, the blood vessel is easy to reflux, the risk of infection is high, and the sheath cannot be left indwelling for a long time. Blood vessels also need to be ligated, which cannot meet the needs of repeated operations on arteries

[0007] In summary, there is an urgent need for a femoral artery puncture sheath that can be placed in animals and is convenient for repeated monitoring or treatment operations and its application, but there is no report about this puncture sheath
