Embodiment Construction

[0017] Combine below Figure 2-3 The present invention will be further described.

[0018] The outlet and inlet of the pump body of the axial-flow blood pump 1 driven by the external wireless energy transmission mode are provided with banding grooves, and the cross-sectional shape of the banding grooves is semicircular or rectangular, so as to adapt to the shape of the cross-section of the strapping band . Two sections of artificial blood vessels 3 for anastomosis of appropriate length are respectively connected to the outlet and inlet of the pump body, and fastened to the banding groove with a bandage. The outlet of the pump body is also provided with a pump outlet support ring 2, and the end of the pump outlet support ring at the entrance of the bifurcation vessel of the aortic arch is cut off in a streamlined manner (such as figure 2 ). Wherein the pump outlet support ring 2 is made of biocompatible material, and the material has plasticity.

Abstract

The invention relates to an auxiliary circulation blood pump adopted in serially connecting operation modes and an installing method of the auxiliary circulation blood pump and belongs to the field of biomedical engineering. The blood pump belongs to an implanted heart chamber auxiliary blood pump and mainly consists of an axial-flow type blood pump (1), a pump outlet support ring (2), an artificial blood vessel (3) for anastomosis and a coronary bypass tube (4). A case of the blood pump (1) is in a cylindrical shape, two ends of the pump case are designed with arc-shaped grooves, the arc-shaped groove are used for binding the artificial blood vessel (3), the artificial blood vessel (3) is used for being coincided with the artery, and the support ring (2) is arranged in an aorta arch of the pump outlet. During the installation, the artificial blood vessel is bound on the pump case in advance, the in vitro auxiliary circulation is carried out in the operation, then, the aorta is pinched off, the support ring is implanted in the aorta arch direction, the artificial blood vessel at the pump outlet is coincided with the aorta, and finally, the artificial blood vessel at the pump outlet part of the blood pump is coincided with the root part of the aorta. The blood pump is fixedly arranged inside the aorta and is then matched with the coronary artery bypass operation for transplanting. The auxiliary circulation blood pump has the advantages that the myocardial blood supply can be obviously improved, and the heart recovery is favorably realized.

Description

technical field [0001] The invention relates to a serially connected auxiliary circulation blood pump and an installation method thereof, belonging to the field of biomedical engineering. Background technique [0002] Assisted circulatory devices are the primary means of maintaining hemodynamic stability in patients with pump failure. The blood pump, which is the core component of the assisted circulation device, is usually connected to the heart bypass, and the blood pump is placed between the apex of the heart and the aorta. figure 1 It is a bypass connection type auxiliary circulation mode: the apex of the natural heart 5 is connected to the blood pump inlet catheter 7, passes through the bypass blood pump 8, and then connects to the aortic arch 6 through the blood pump outlet catheter 8. This type of auxiliary circulation method will damage the apex of the heart, the operation is complicated and not conducive to heart recovery; it will damage the function of the heart v...
