Further, there is reserved opening between the pump and liquid outlet.
The purpose of design of external capacity modulation, is the systemic circulation relative to whole body, establishes a small blood circulation, reach
To following target:
1, improve the blood supply obstacle of local organization or organ；
2, the blood circulation of local patholoic change organ is isolated, avoids that its hetero-organization of body or organ are caused to damage, such as limb
Myoglobins caused by the local infection or lower limb crush syndrome of body enters blood；
3, guarantee the vascular patency of diseased region, and keep histoorgan vigor, the limbs of detachment when hurting such as limb dividing.
The utility model has the following beneficial effects:
1, liquid inlet conduit connection artery perhaps lead by vein eluate conduit connection vein on the other side or artery, feed liquor
After pipe and eluate conduit are connected to arteriovenous, regional flow's partial circulating is formed, local blood flow is adjusted by pump, adjusts different groups
It knits or the capacity status of organ；
2, the two-chamber design of insertion end A, can reduce absorption of the conduit to vascular wall, and the rear end insertion end A is cambered surface, You Qianzhi
Outer diameter is gradually reduced afterwards, is conducive to merging human body；
3, the front end insertion end B is cambered surface, and outer diameter is gradually reduced from back to front, can reduce the influence to intravascular blood flow,
Convenient for being placed in human body, inlet opening can allow blood flow in conduit to pass through from the side of conduit, in side wall to be irrigated；
4, thread eye is arranged in the rear end insertion end A and the front end insertion end B, convenient for merging human body.
Detailed description of the invention
Fig. 1 is utility model diagram；
In figure: 1- insertion end A, 11- inner tube, 111- inlet opening A, 12- outer tube, 121- inlet opening B, 2- pump, 3- insertion end
B, 31- fluid hole, 32- thread eye, 4- filter, 5- oxygenator, 6- liquid inlet conduit, 7- eluate conduit, 8- reserved opening.
Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing, to this reality
It is further elaborated with novel.
As shown in Figure 1, external capacity modulation disclosed by the utility model, including liquid inlet conduit 6,7 and of eluate conduit
Pump 2,6 front end of liquid inlet conduit connection pump 2 input ports, 7 rear end of eluate conduit connection pump 2 delivery outlets, 6 rear end of liquid inlet conduit be provided with into
Liquid mouth, inlet connect insertion end A1, and insertion end A1 is double lumen tube, including inner tube 11 and outer tube 12, inner tube 11 are provided with inlet opening
A111, inlet opening A111 have one or more, and inlet opening A111 is distributed in 11 rear end face of inner tube and/or side wall, 12 both ends of outer tube
Face is cambered surface, and 12 both ends outer diameter of outer tube is gradually become smaller from centre to both ends, and 12 back-end central of outer tube is provided with thread eye 32, outer tube
