Problems solved by technology

However, in the process of extracorporeal circulation of blood, for example, due to human body movement, etc., the puncture needle is accidentally pulled out from the puncture part of the patient, and it is separated from it, especially when the venous side puncture needle is pulled out, there is a risk of blood leakage. danger to the outside

Abstract

Provided is a blood purification apparatus that detects catheter dislodgement, the apparatus comprising: an arterial electrode (D1); a venous electrode (D2); a power source (8) capable of sending current through an arterial catheter (a) and a venous catheter (b) inserted into a patient; a body surface electrode (D3) closely attached to the surface of the patient's body; a detecting means (9) capable of taking the patient's pulse on the basis of electrical signals detected by the body surface electrode (D3); a monitoring means (10) capable of monitoring, in real-time, the current flowing through the arterial electrode (D1) or the venous electrode (D2), and changes, detected by the detecting means (9), in impedance in the patient's body; and a determining means (11) capable of determining, on the basis of a change in impedance monitored by the monitoring means (10), a dislodgement state in which the arterial catheter (a) or venous catheter (b) has withdrawn from the patient.

Description

technical field [0001] The present invention relates to a blood purification device capable of purifying the blood of a patient undergoing extracorporeal circulation in an arterial side blood circuit and a venous side blood circuit. Background technique [0002] Generally, in dialysis treatment, the following dialysis treatment device is used, and the dialysis treatment device includes: a blood circuit for extracorporeal circulation of the patient's blood; a dialyzer connected to the middle of the blood circuit A peristaltic blood pump; a dialysis device body, the dialysis device body is between the dialyzer and the dialyser, and the dialysate is introduced or exported, and water can be removed while performing hemodialysis treatment. Since the dialysis treatment performed by such a dialysis treatment device is usually carried out for 4 hours a day, the blood circulation dynamics of the patient in treatment changes greatly, and it is particularly effective and sure to preven...
