Problems solved by technology

[0009] Aiming at the defects in the prior art, the present invention provides a percutaneous catheter-type ventricular assist device to solve the problem that the device in the traditional technology cannot effectively increase the circulating blood supply of the lower limbs due to the implantation of the auxiliary device during use. , it is easy to bring the risk of ischemia in the lower limbs; when blood is introduced into the ventricle, because the blood flow vertically impacts the vessel wall and valve, it is prone to aggravate reflux; and the dual catheters drain the venous blood separately, which increases vascular complications and infection risk issue

Embodiment Construction

[0035] Embodiments of the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, so they are only examples, and should not be used to limit the protection scope of the present invention.

[0036] Such as figure 1 As shown, the catheter-type ventricular assist device for percutaneous intervention includes a main drainage tube set and an auxiliary drainage tube set arranged side by side.

[0037] The main drainage tube set includes an inlet conduit 4 and an outlet conduit 5 arranged side by side.

[0038] The auxiliary drainage tube set includes a bypass conduit 6 connected in parallel with the outlet conduit 5 .

[0039] A constraining assembly coaxially arranged between the inlet end of the inlet conduit 4 and the outlet end of the outlet conduit 5 is also provided.

[0040] The constraint ass...

Abstract

The invention discloses a percutaneous intervention catheter type ventricular auxiliary device, and relates to the technical field of cardiac surgery devices. The percutaneous intervention catheter type ventricular auxiliary device comprises a main drainage tube group and auxiliary drainage tube groups arranged in parallel. The problems that in the using process of a device in the traditional technology, due to implantation of an auxiliary device, lower limb circulation blood supply cannot be effectively increased, and the risk of lower limb ischemia is likely to be caused are solved; when blood is guided into a ventricle, backflow aggravation easily occurs due to the fact that blood flow vertically impacts a blood vessel wall and a valve; and two catheters are used for guiding flowing venous blood respectively, so that vascular complications and infection risks are increased.

Description

technical field [0001] The invention relates to the technical field of devices for heart surgery, in particular to a percutaneous catheter-type ventricular assist device. Background technique [0002] Ventricular assist is a life support technology, which has saved many lives as an important treatment for patients with acute cardiac events and end-stage heart failure. Extracorporeal membrane oxygenation, represented by ECMO, is currently the commonly used ventricular assist technology in clinical practice. Its working principle is to draw venous blood from the body through a centrifugal pump, exchange gas through a membrane oxygenator outside the body, and then reinfuse it into arterial blood. arteries, thereby achieving full or partial replacement of the function of the heart and / or lungs. However, the structure of the ECMO system is complex, and the design of separate drainage of venous blood with dual catheters greatly increases the risk of vascular complications and inf...
