Problems solved by technology

The operation process is complicated. Once the saline injection channel is wrong due to the negligence of the doctor, it will cause lack of perfusion fluid in some areas, resulting in thrombus accumulation or overheating, and more perfusion ports at the proximal end of the perfusion system will also lead to changes in the design of the perfusion channel. Complicated, for example, an additional hole in the drive shaft is required to allow the irrigation system between the middle casing and the drive shaft to form a circuit

Abstract

The invention relates to a percutaneous blood pump and an injection system thereof. The injection system comprises a starting part, a transmission assembly, an irrigating part and a reflux part whichare sequentially connected, wherein the transmission assembly comprises a transmission shaft, a net basket pipe and an outer sheath pipe; a first irrigating channel is formed along the outer surface of the transmission shaft; a second irrigating channel is formed along the inner surface of the outer sheath pipe; the first irrigating channel can communicate with the second irrigating channel; an irrigating opening which communicates with the second irrigating channel is formed in the irrigating part; and a reflux opening which communicates with the first irrigating channel is formed in the reflux part. According to the injection system of a percutaneous axial flow blood pump disclosed by the invention, the first irrigating channel can communicate with the second irrigating channel, so thatthe two irrigating channels can be irrigated simultaneously only through forming one irrigating opening; and the percutaneous blood pump is simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a percutaneous blood pump and a perfusion system thereof. Background technique [0002] In modern times, cardiovascular disease has become a major cause of human death. Heart transplantation is an effective means of treating patients with severe heart disease. However, in reality, there are far more heart recipients than heart donors, resulting in the death of patients waiting for heart transplantation. . The percutaneous axial blood pump can assist the heart to pump blood, and is a commonly used device in the auxiliary treatment of cardiovascular diseases. [0003] Generally, the percutaneous axial flow blood pump may have problems such as thrombus blockage or overheating of the bearing during use. Therefore, it is necessary to regularly perfuse normal saline in the perfusion system of the percutaneous axial flow blood pump to prevent thrombus formation and carry out maintenance ...
