Embodiment 1

[0019] See attached Figure 1~2 . A blood purification device with built-in intelligent citric acid anticoagulation technology, including a host 1; the host 1 is provided with an arterial pipeline 2, a blood pump 3, a dialyzer 4, a venous pipeline 5, a waste liquid storage device 6, Waste liquid output line 7, waste liquid pump 8, dialysate container 9, dialysate input line 10 and dialysate pump 11; the blood inlet of the dialyzer 4 is connected to the arterial line 2, and the arterial line 2 A blood pump 3 is provided on the top; the blood outlet of the dialyzer 4 is connected to the venous line 5; the dialysate inlet of the dialyzer 4 is connected to the dialysate container 9 through the dialysate input line 10, and the dialysate input tube A dialysate pump 11 is provided on the road 10; the waste liquid outlet of the dialyzer 4 is connected to the waste liquid containing device 6 through the waste liquid output pipeline 7, and the waste liquid output pipeline 7 is provided...

Embodiment 2

[0021] See attached Figure 1~2 . On the basis of Embodiment 1, the host computer 1 is also provided with a calcium concentration detection sensor I17 and a calcium concentration detection sensor II18; the calcium concentration detection sensor I17 is arranged on the arterial pipeline 2 upstream of the citric acid input pipeline 15 Above; the calcium concentration detection sensor II18 is set on the venous line 5 upstream of the calcium solution input line 12 . It can be seen from the above structure that the calcium concentration detection sensor I17 is used to monitor the calcium ion concentration in human blood before the input of citric acid. Cause hypocalcemia in the human body; if the calcium ion is in the normal range, it is necessary to maintain the calcium solution flow provided by the calcium solution injection pump 13 to maintain the free calcium concentration in the human body at 1.0-1.3mmol / L; if the calcium ion concentration is too high, it is necessary to Redu...

Embodiment 3

[0024] See attached Figure 1~2 . On the basis of Embodiment 2, the host 1 is also provided with a controller; the blood pump 3, waste liquid pump 8, dialysate pump 11, citric acid pump 16, calcium solution injection pump 13, calcium concentration detection The sensor I17 and the calcium concentration detection sensor II18 are respectively electrically connected to the controller. It can be seen from the above structure that the blood pump 3, the waste liquid pump 8, the dialysate pump 11, the citric acid pump 16, the calcium solution injection pump 13, the calcium concentration detection sensor I17, and the calcium concentration detection sensor II18 not only have the function of providing power, And all have the function of metering flow, belong to the prior art, the product that can be purchased in the market, the specific principle is not repeated here. The blood pump 3 transmits the blood flow information to the controller; the waste liquid pump 8 transmits the waste li...

Abstract

The invention discloses a blood purification equipment with a built-in intelligent citric acid anticoagulation technology, and belongs to the field of blood purification. A calcium solution input pipeline, a calcium solution injection pump, a citric acid containing device, a citric acid input pipeline and a citric acid pump are further arranged on a main machine; the citric acid containing device is connected to an artery pipeline on the upstream of a blood pump through the citric acid input pipeline, and the citric acid pump is arranged on the citric acid input pipeline; and the calcium solution injection pump is connected with a vein pipeline through the calcium solution input pipeline. According to the blood purification equipment with the built-in intelligent citric acid anticoagulation technology, a citric acid anticoagulation function is built in, citric acid and a calcium solution are input synchronously and controllably, and a feedback regulation function is achieved, so that the concentration of free calcium in in-vitro blood is within a standard range, the in-vitro blood anticoagulation effect is guaranteed, lost calcium in waste liquid is accurately made up, the concentration of free calcium in a human body is maintained in a standard range, and hypocalcemia of the human body is avoided.

Description

technical field [0001] The invention belongs to the field of blood purification, and in particular relates to a blood purification device with built-in intelligent citric acid anticoagulation technology. Background technique [0002] CRRT (continuous renal replacement therapy) is continuous renal replacement therapy. It is a general term for all treatments that continuously and slowly remove water and solutes. It is a blood purification technology that supports the functions of human organs. Continuous blood purification therapy is a process that requires extracorporeal circulation of blood. The contact of blood outside the body with the pipeline and dialysis membrane can trigger the body's coagulation mechanism, thereby forming thrombus to block the pipeline and filter. Therefore, anticoagulants such as heparin and citric acid must be used during the blood purification treatment to prevent the formation of thrombus, so as not to cause blockage of the dialyzer and pipeline, ...
