Embodiment Construction

[0070] Such as Figure 1-8 As shown, a blood pumping device 35 includes a blood pump mechanism 1. The blood pump mechanism 1 includes a housing 7 with a cavity inside. The housing is provided with an air inlet 20 communicating with the cavity. An elastic liner 8 with an air inlet is provided, and the shape of the liner 8 is the same as that of the cavity in the outer shell 7, and when the gas in the liner 8 is filled, the entire cavity can be filled. The air inlet end of inner bag 8 is fixed on the air inlet 20 place of shell 7 by inner bag pressing plate 14 and screw 13.

[0071] A blood inlet tube 10 and a blood outlet tube 12 communicating with the inner cavity of the housing 7 are arranged side by side on the other side of the housing 7 opposite to the air inlet 20 .

[0072] Between the blood input tube 10 and the cavity in the shell, an input check valve 9 that allows blood to flow into the cavity of the shell 7 in one direction is provided; between the blood output tub...

Abstract

The invention discloses a blood pumping device, which comprises a blood pump mechanism; the blood pump mechanism comprises a shell in which a cavity is formed; an air inlet communicated with the cavity is formed in the shell; an elastic liner with an air intake is arranged in the cavity; the air intake of the liner is fixedly arranged at the air inlet of the shell; the other side, which is opposite to the air inlet, of the shell is provided with a blood inlet pipe and a blood outlet pipe side by side, wherein the blood inlet pipe and the blood outlet pipe are communicated with the cavity in the shell; an inlet check valve capable of enabling blood flowing into the cavity in the shell unidirectionally is arranged between the blood inlet pipe and the cavity in the shell; an outlet check valve capable of enabling blood flowing out from the cavity in the shell is arranged between the blood inlet pipe and the cavity in the shell; the side, with the air intake, of the shell is provided with an air pump for filling in or pumping gas from the liner. The blood pumping device has the advantages that mechanical injury on blood cells is small; the maximum outlet pressure and blood volume can be independently adjusted; blood can be properly warmed to reduce coagulation, and cancer cells in the blood can be killed.

Description

technical field [0001] The invention belongs to the field of medical equipment, and in particular relates to a blood pumping device suitable for driving blood circulation. Background technique [0002] Research on various types of artificial hearts, such as total artificial hearts, various ventricular assist devices, and extracorporeal membrane oxygenation, has made continuous progress at home and abroad. In particular, left ventricular assist devices and extracorporeal membrane oxygenation (ECMO for short) have been more clinically applied and have played an important role in improving the level of first aid in the medical field. However, no matter what kind of artificial heart device, the pump that drives the blood circulation mostly adopts a centrifugal or axial flow pump. This type of blood pumping device uses a motor to drive the blades to rotate, so that the blood flows in one direction, and its high-speed rotation The leaves of the heart will cause unavoidable mechan...
