Room is cooperatively connected by more connecting tubes and multiple second sub-chamber so that fluid media (medium) first chamber, connecting tube,
It circulates between second chamber by serpentine path, the connecting tube passes through blood recovery pipe, and the interlude of connecting tube is located at blood
It feeds back in pipe.
As a kind of preferred embodiment of the utility model, the fluid media (medium) import and one at blood recovery pipe liquid feeding end
A first sub-chamber is connected, and the fluid media (medium) outlet is connected with second sub-chamber at blood recovery pipe outlet end.
As a kind of preferred embodiment of the utility model, the outside of the outer tube is provided with aerogel blanket insulating layer；It mentions
High heat insulation effect.
As a kind of preferred embodiment of the utility model, speed governing valve is provided at the liquid feeding end of the blood recovery pipe；Into
And regulating flow quantity.
The beneficial effects of the utility model are that the haemodialysis feeds back pipe both can be right from the outside of blood recovery pipe
Blood carries out heating and thermal insulation, also can carry out heating and thermal insulation to blood from the inside of blood recovery pipe by connecting tube, and then significantly
Heating and thermal insulation effect is improved, and has the characteristics that homogeneous heating, in addition, connecting tube passes through blood recovery pipe, to a certain extent
It can reduce flowing velocity of the blood in blood recovery pipe, virtually extend the heating and thermal insulation time, to guarantee to flow into people
The blood temperature of body is close at 36 DEG C~38 DEG C with human body temperature.
Detailed description of the invention
Fig. 1 is the cross-sectional view that the utility model haemodialysis feeds back pipe.
