In this embodiment, the replacement fluid pump 130 rotates so that the replacement fluid supplied from the replacement fluid port 170 flows into the second drip chamber 250 through the replacement port 253 .

Also in the blood purification apparatus according to the second embodiment of the present invention, when the blood circuit 300 is attached, the planned attachment position of the blood circuit 300 emits light. Since it can be attached to the device main body 100, erroneous attachment of the blood circuit 300 can be suppressed.

In particular, when the blood circuit 300 is attached, the planned attachment position 220g of the main line 220, the expected attachment position 221g of the branch line 221, and the expected attachment position 222g of the replenishment line 222 emit light in different colors. 220, the branch line 221, and the supplementary line 222 can be prevented from being erroneously attached.

In addition, when a problem occurs, it is possible to easily deal with the problem by illuminating the location of the problem in the blood purification apparatus main body 100 .

Furthermore, blood purification apparatus main body 100 displays the pressure value in blood circuit 300 with different luminescent colors according to the pressure value, so that the state of blood flow in blood circuit 300 can be easily grasped. .

The blood purification apparatus according to this embodiment may also have a configuration in which wearable glasses are provided in place of the light-emitting portion of the blood purification apparatus main body 100, as in the modification of the first embodiment.

It should be noted that the above-described embodiment disclosed this time is an example in all respects, and does not serve as a basis for restrictive interpretation. Therefore, the technical scope of the present invention is not to be interpreted only by the above-described embodiments, but is defined based on the claims. In addition, all changes within the meaning and range of equivalence to the scope of claims are included.
