Blood pump method based blood doping device

Abstract

The invention discloses a blood pump method based blood doping device. The device comprises a bottom plate and a support, wherein the support is fixedly installed at the top end of the bottom plate; anegative pressure pump and a temperature control cavity are fixedly connected to the positions, located at the top of the bottom plate, of two sides of the support respectively; and an anticoagulation cavity is fixedly connected to the upper end of the interior of the support. When entering the anticoagulation cavity, blood can be uniformly drained to the inner wall of the anticoagulation cavityunder the action of an umbrella-shaped plate, meanwhile, an anticoagulant in a liquid storage cavity is effectively input into the inner wall of the anticoagulation cavity through a spray head by a circulating pump, and the spray head is tangent to the outer wall of the anticoagulation cavity, so that the anticoagulant sprayed by the spray head can be sprayed out around the inner wall of the anticoagulation cavity to form an annular vortex, and the blood is fully mixed with the anticoagulant; the device is simple and practical; due to the design of an arched heating plate in the temperature control cavity, the contact area between the heating plate and the blood is effectively increased; meanwhile, the blood with the too low temperature is heated through a temperature controller and an electric heating wire, so that the temperature of the blood returns to the temperature suitable for the human body; and the device is safe and practical.

Description

technical field [0001] The invention relates to the technical field of blood reinfusion, in particular to a blood pump method blood reinfusion device. Background technique [0002] Blood reinfusion, using your own blood to perform surgery on yourself, is mainly suitable for patients with a large amount of bleeding during the operation. The safety of blood reinfusion is higher than that of allogeneic blood transfusion. When traditional blood reinfusion, blood needs to be added Anticoagulant, so as to prevent blood coagulation, while the traditional blood anticoagulant is mostly mixed with blood and anticoagulant by stirring method. When it is used, it is not suitable for mixing blood with flow, and the blood needs to be collected In the container, and then stirred and mixed, it can not effectively add the anticoagulant quickly and evenly when the blood circulates according to the needs, which has certain defects, and the traditional blood pump method is stable when the blood ...
