Description

A push-injection system for venous pot flushing during heparin-free dialysis

technical field

The utility model belongs to the field of hemodialysis, in particular to a push injection system used for venous pot flushing in the heparin-free dialysis process.

Background technique

In the process of hemodialysis, some patients are not suitable to use the existing anticoagulant due to active bleeding, perioperative period and other reasons, and non-anticoagulant dialysis treatment is needed to avoid causing or aggravating the bleeding tendency, commonly known as heparin-free dialysis. The most common complication of heparin-free dialysis is the coagulation of the dialyzer and the dialysis circuit tube, which makes the dialysis unable to continue, such as replacing the dialyzer and the circuit, which will increase the economic burden of the patient; what is more serious is that if the dialysis circuit tube is completely blocked (Among them, the venous pot is the most common), which will lead to the inability of blood to be returned to the patient, so that the patient loses a large amount of blood and increases the degree of anemia. Therefore, how to prevent heparin-free dialysis coagulation has become an important part of maintaining the patient's extracorporeal blood circulation.

For patients with high-risk bleeding who undergo heparin-free dialysis, effective measures can prevent blood coagulation in the dialyzer and tubing, thereby ensuring the smooth progress of dialysis. At present, the nursing intervention measures adopted in dialysis are mainly physiological saline flushing, which is a relatively safe method, and its operation methods include intermittent saline flushing, continuous saline infusion, and warm saline flushing. Since these methods all add physiological saline from the small tube before the blood pump to dilute the blood and flush the tube wall, they have a good preventive effect on the coagulation of the arterial jug and the dialyzer; but when the blood flows through the dialyzer, It will become viscous, that is, the effect of preventing blood coagulation in the tube after the dialyzer will be weakened, so it is inconvenient to observe the blood coagulation of the venous pot.

Since the prevention of coagulation in the venous pot is a crucial part of the whole coagulation process, and the coagulation in the venous pot is the main reason for early discontinuation of heparin-free dialysis, it will not only shorten the dialysis time, but also lose a large amount of blood, seriously affecting the prognosis of patients . In order to ensure the smooth progress of heparin-free dialysis and prevent and reduce blood coagulation in the venous jug, it has been used to flush the venous jug separately with normal saline. However, the inventors of the present utility model have found that in the existing process of separately flushing the venous pot, there is no special system or device to statically push the physiological saline for venous pot flushing, so it is very difficult to operate. inconvenient.
