Background
Hemodialysis is one of the renal replacement therapy modes for patients with acute and chronic renal failure. The method comprises the steps of draining in-vivo blood to the outside of a body through a drainage pipeline, passing through a dialyzer consisting of innumerable hollow fibers, wherein the blood and electrolyte solution (dialysate) with similar concentration of a body are in and out of the hollow fibers, and carrying out substance exchange through dispersion/convection to remove metabolic wastes in the body and maintain the balance of the electrolyte and acid and alkali; at the same time, the whole process of removing excessive water from the body and reinfusion of the purified blood is called hemodialysis.
When hemodialysis, a three-way valve is added on a drainage tube, one end of the three-way valve is connected with an anticoagulant tube, the anticoagulant tube is connected with an anticoagulant supply bag, the effect of adding anticoagulant into blood in the drainage tube is realized through an infusion pump on the anticoagulant tube, but the existing anticoagulant tube has the problem that a catheter is easy to bend at the joint of the three-way valve, and meanwhile, gas mixed in anticoagulant liquid in the tube cannot be removed quickly and effectively, so that the three-way valve has certain defects during use.
Disclosure of Invention
The present utility model is directed to an anticoagulant line for hemodialysis, which solves the problems set forth in the background art.
In order to achieve the above purpose, the present utility model provides the following technical solutions:
the utility model provides an anticoagulant pipeline for hemodialysis, includes the pipe, and the inlet and the liquid outlet of pipe are connected with anticoagulant supply bag and three-way valve respectively, first pipe clamp, drip kettle, infusion pump, third pipe clamp and check valve have been set gradually by the direction of inlet to the liquid outlet on the pipe.
As a further scheme of the utility model: the interface of the three-way valve corresponding to the conduit is an arc-shaped interface.
As still further aspects of the utility model: the catheter is provided with a liquid discharge three-way valve positioned between the infusion pump and the third catheter clamp, the liquid discharge three-way valve is provided with a liquid discharge pipe, and the liquid discharge pipe is provided with a second catheter clamp.
Compared with the prior art, the utility model has the beneficial effects that:
1. by arranging the one-way valve, the problem that blood in the drainage tube enters the catheter through the three-way valve after the anticoagulant stops being supplied is avoided, the problem that the blood enters the infusion pump due to untimely closing of the first catheter clamp is avoided, and the use safety is improved;
2. by designing the connecting port of the three-way valve corresponding to the catheter as an arc-shaped connecting port, the problem that the catheter is bent when the three-way valve is connected is avoided, the problem that anticoagulant is blocked due to bending of the catheter is avoided, and the use safety is improved;
3. through setting up flowing back three-way valve, the second pipe clamp is in the normal close state, after the transfer pump detects the anticoagulant in the pipe has air, presss from both sides tight third pipe clamp, opens the second pipe clamp this moment, opens the transfer pump, discharges the anticoagulant liquid that has air that the transfer pump detected through flowing back three-way valve, closes the second pipe clamp afterwards, opens the third pipe clamp, and the pipe alright normal supply anticoagulant liquid has avoided the air to get into in the blood, has improved safety in utilization.
In conclusion, the anticoagulant pipeline can effectively avoid the problem that the catheter is pliable at the joint of the three-way valve, and simultaneously can rapidly and effectively remove the gas mixed in the anticoagulant liquid in the pipeline, so that the use safety is improved.
