Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
Every other embodiment obtained, fall within the protection scope of the utility model.
Unless otherwise defined, all technical and scientific terms used herein are led with the technology for belonging to the utility model
The normally understood meaning of the technical staff in domain is identical.Terminology used in the description of the utility model herein only be
The purpose of description specific embodiment, it is not intended that in limitation the utility model.Term " and or " used herein packet
Include any and all combinations of one or more related listed items.
Refering to fig. 1, the blood back device in an embodiment of the present invention, including upper drainage tube 1, Murphy's tube 2, lower drainage tube
4, the Murphy's tube 2 is set between upper drainage tube 1 and lower drainage tube 4, the upper drainage tube 1, Murphy's tube 2, lower drainage tube 4
It is an integral structure；Filter screen 3, the screw thread of the port of the upper drainage tube 1 and short infusion cylinder 5 are equipped in the Murphy's tube 2
Connector 6 is flexibly connected, and the lower drainage tube 4 is connected with infusion connector.
Wherein, one end that the infusion connector 12 exports is equipped with internal layer 14, outer layer 13, and the inner wall of the outer layer 13 is equipped with
Screw thread, by the double action of internal layer 14, outer layer 13, the conduit for making infusion connector 12 be connected with patient connect it is stronger, and
It is convenient and efficient.Furthermore it is possible to blood volume controller be set on the lower drainage tube 4, for controlling the size of blood flow.
In concrete operations, blood back device must be in a vertical state always, or more drainage tube 1 than lower drainage tube 4
It is much longer.Wherein, 1 length of upper drainage tube is preferably 30cm, and lower 4 length of drainage tube is preferably 120cm.
As another preferred embodiment of the utility model, it is additionally provided with exhaust apparatus 10 in the Murphy's tube 2, works as blood back
There are when air in device, can quickly remove.In addition, it is additionally provided with one-way flow component on the filter screen 3 of the Murphy's tube 2,
The one-way flow component is unidirectional anti-blood back valve, can prevent blood backflow in this way.
Referring to Fig.2, a kind of venous chambers with blood back device in one specific embodiment of the utility model, including venous chambers 7 and return
Blood device, the blood back device can be flexibly connected by the nipple 6 of short infusion cylinder 5 with the fluid infusion 9 of venous chambers 7, in this way, quiet
Arteries and veins pot 7 can establish new Temporary access when blocking by blood back device, reduce the loss of patient blood.Wherein, described
It is equipped with pressure detector 8 and filter device 11 in venous chambers 7, blood samples of patients pressure is detected at any time, anti-can also be stopped blooding
Bolt enters in human body, further ensures the health of patient.
Specific implementation process: when carrying out normal hemodialysis, the fluid infusion 9 of venous chambers 7 is mainly connect with nutrient solution, is led to
The circuits of venous chambers 7 is crossed by blood recovery in patient body；Lead to not when Severe blockage occurs for the filter device 11 of venous chambers 7
When blood back, changes the nutrient solution of fluid infusion 9 into blood back device, i.e., lead to the fluid infusion 9 of venous chambers 7 and the upper drainage tube 1 of blood back device
The nipple 6 of too short infusion cylinder 5 connects, and lower drainage tube 4 is connected to the vein end of patient's hemodialysis pipe by infusion connector 12；So
Just new Temporary access is established, the blood in venous chambers 7 is fed back in patient body with 50ml/h speed, reduces patient blood
It loses.After the blockage problem of venous chambers 7 is disposed, blood back is thought highly of and newly gains nutrient solution, restores circuit.
In blood dialysis, since the volume of venous chambers is larger (about 200~400ml), if blocking, which occurs, to incite somebody to action
Blood in venous chambers is all lost, and restores circuit as early as possible.The utility model avoids conventional hemodialysis in the process in hemodialysis
Pipeline venous chambers can only a whole set of the phenomenon that abandoning, losing patient blood largely when blocking.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
