Problems solved by technology

[0006] The amount of water to be removed (water removal speed) during water removal is controlled by controlling the drive of the water removal pump, but there is a problem that when the water removal is performed rapidly or excessively, the patient's circulating blood volume decreases excessively, This will cause blood pressure to drop or shock, etc. On the other hand, if the water removal rate is slow, the entire treatment time will be prolonged, which will increase the burden on the patient

Embodiment Construction

[0053] Hereinafter, embodiments of the present invention will be specifically described with reference to the drawings.

[0054] The blood treatment apparatus of the first embodiment is composed of a blood purification apparatus that circulates and purifies the patient's blood outside the body. It consists of a monitoring device for dialysate and a dialysate supply device for preparing dialysate.

[0055] This blood purification device, such as figure 1 As shown, it is mainly composed of a processing mechanism 11 for performing predetermined processing on the collected patient's blood, a measuring mechanism 12 for measuring the hematocrit value of a blood parameter indicating the state of the patient's blood, and according to the measurement mechanism 12 The measured hematocrit value is composed of a control unit 13, a storage unit 15 and an indication unit 14 for controlling the processing conditions.

[0056] blood circuit 1, such as figure 2 As shown, it mainly consists...

Abstract

The present invention provides a blood treatment device and methods of blood treatment to provide an individual patient with the most suitable blood treatment and reduced treatment duration. Specifically, the invention provides a blood treatment device comprising a treating means (11) that treats blood collected from a patient; a measuring means (12) that measures parameters of the patient's blood and indicates blood condition; a controlling means (13) that controls the treatment procedures based upon the blood parameters; a storing means (15) that records an ideal patient-specific blood parameter curve for the treatment duration; and a directing means (14) that directs the control by the controlling means (13) so that the measured blood parameters approximate to the ideal blood parameter curve A by comparing the measured blood parameters with the ideal blood parameter curve recorded by the storing means (15).

Description

technical field [0001] The present invention relates to a blood treatment device and a blood treatment method for performing predetermined treatment after collecting blood from a patient. Background technique [0002] Generally, in dialysis treatment, a blood circuit mainly composed of a flexible tube is used to circulate the patient's blood outside the body. The blood circuit mainly includes an arterial side blood circuit with an arterial side puncture needle mounted on the tip for taking blood from the patient, and a venous side blood circuit with a venous side puncture needle mounted at the top end to return blood to the patient. A dialyzer is installed between the blood circuit and the venous side. [0003] In addition, a thin-type blood pump is arranged on the arterial side blood circuit, and the patient's blood is collected from the arterial side puncture needle by driving the blood pump, and the extracorporeal circulation is performed in the arterial side blood circu...
