Movable hanging type artificial heart-lung machine blood pump

Abstract

The invention discloses a movable hanging type artificial heart-lung machine blood pump. The movable hanging type artificial heart-lung machine blood pump comprises a movable chassis, an upright column and a multi-degree-of-freedom adjustable pump frame. The upright column is vertically fixed on the movable chassis, and the multi-degree-of-freedom adjustable pump frame is installed on the uprightcolumn. The multi-degree-of-freedom adjustable pump frame includes an outer sleeve, an inner rod, a telescopic arm, casters, and a blood pump. The inner rod is inserted into the outer sleeve, and theouter sleeve is connected to the upright column on the movable chassis through the telescopic arm. The blood pump is fixedly installed on the top of the inner rod, and casters are installed on the bottom of the outer sleeve. Limit adjustment screws are set at the inner and outer ends of the telescopic arm respectively, and limit adjustment screws are set between the outer sleeve and the inner rod.A pump head of the blood pump can move in multi-degree-of-freedom, so that the length of a perfusion pipeline can be effectively shortened and the area of contact between an extracorporeal circulation artificial material and the blood can be reduced, thereby reducing the amount of pre-rinsing fluid perfusion of a patient during a surgery.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a movable suspension type artificial heart-lung machine blood pump. Background technique [0002] Cardiopulmonary bypass technology is the most critical link in the cardiac surgery process, that is, the use of artificial heart and lungs for life support, which temporarily replaces the patient's own cardiopulmonary function during cardiac surgery. In the requirements for artificial heart and lung, the blood pump, as the power source of the artificial heart, is placed in the most important position. The blood pump cooperates with the extracorporeal circulation pipeline and intubation, and finally connects with the human body's large arteries and veins to realize the blood flow. The constant input and output of the cycle, the artificial heart. Due to the contact between human blood and artificial pipelines (foreign surfaces of non-human blood vessels) in extraco...

AI Technical Summary

Problems solved by technology

[0003] Extracorporeal circulation artificial heart-lung machines have always fixed four to five pump heads. The pump heads are arranged in a line and cannot be moved. It is necessary to use extracorporeal circulation lines of different lengths to match and connect with them. The blood and the membrane oxygenator are also placed at a low position, so the matching length of the oxygenator and the pump head pipeline is long and fixed, the system prefills a large amount, the degree of blood dilution is also large, and the degree of activation of the inflammatory response is high. Many organ complications
