Embodiment Construction

[0027] The present invention will be further described below in conjunction with specific embodiments.

[0028] Such as Figure 1 to Figure 3 As shown, the solenoid-driven blood pump system of the present invention includes a pump body, a first blood flow chamber 11 , a second blood flow chamber 12 and the like.

[0029] Both ends of the pump body are respectively connected to the first blood flow chamber 11 and the second blood flow chamber 12, and the electromagnetic coil drive chamber 2 in the pump body. The outside of the electromagnetic coil driving chamber 2 is overlapped with left, middle and right groups of bottom coils 31, 32, 33 (three groups) and left and right groups of top layer coils 41, 42 (two groups), and the electromagnetic coil driving chamber 2 is closely matched There is a permanent magnet mover 5, and the permanent magnet mover 5 can move under the control of an external coil group. The permanent magnet mover 5 divides the inside of the electromagnetic ...

Abstract

The invention relates to an electromagnetic coil driving type blood pump system. Two ends of a pump body are respectively connected with a blood flowing cavity; an electromagnetic coil driving cavity is arranged in the pump body; three bottom coils and two top coils are wound outside the electromagnetic coil driving cavity in an overlapping manner; a permanent magnetic rotor is closely fit in the electromagnetic coil driving cavity, and can move under control of the external coil group; the inside of the electromagnetic coil driving cavity is separated into a first work zone and a second work zone by virtue of the permanent magnetic rotor; a sealing elastic film is arranged on the joint of the blood flowing cavity and the electromagnetic coil driving cavity; the edge of the sealing elastic film is tightly clamped by internal and external pipe threads on the joint of the blood flowing cavity and the electromagnetic coil driving cavity to form a seal state together with a seal ring; and a flow-in mechanical valve and a flow-out mechanical valve are arranged on the blood flowing cavity. According to the electromagnetic coil driving type blood pump system, cardiac impulse can be simulated by controlling the electromagnetic coils, and mechanical injury for blood is minimized.

Description

technical field [0001] The invention relates to a medical device, in particular to an electromagnetic coil driven blood pump system. Background technique [0002] At present, the treatment of acute respiratory distress syndrome (ARDS) mainly replaces traditional mechanical ventilation with extracorporeal membrane oxygenation (ECMO) and interventional lung assistance (pECLA). ECMO can effectively maintain oxygenation and promote carbon dioxide emission. However, ECMO is driven by a centrifugal pump, which requires huge equipment, high personnel and technical requirements, and is expensive, so it is not suitable for widespread deployment. The pECLA system device has the characteristics of no pump drive, less contact area with blood and simple operation. However, it is not suitable for patients with reduced cardiac output or hypotension. [0003] Then, combining the respective advantages and disadvantages of ECMO and pECLA, can we develop a device based on the original techn...
