Abstract

The present teachings provide a blood purification apparatus in which inadvertent replacement of a container bag attached to a hanger portion can be avoided the blood purification apparatus including a holding device capable of holding a container bag that contains a liquid for blood purification treatment, such as dialysate, substitution fluid, or anticoagulant, the blood purification apparatus being capable of performing blood purification treatment using the liquid in the container bag, and the holding device including a hanger portion including an attachment portion to which the container bag can be attached, and movable between a use position and a replacement position, a measuring device capable of measuring the weight of the container bag held by the hanger portion, and a restricting device that restricts attachment and detachment of the container bag to and from the attachment portion when the hanger portion is in the use position.

First claim

1 : A blood purification apparatus comprising:
a holding device capable of holding a container bag that contains a liquid for blood purification treatment, such as dialysate, substitution fluid, or anticoagulant, the blood purification apparatus being capable of performing blood purification treatment using the liquid in the container bag, wherein the holding device includes:
a hanger portion including an attachment portion to which the container bag can be attached, and movable between a use position in which the container bag is used and a replacement position in which the container bag is replaced,
a measuring device capable of measuring the weight of the container bag held by the hanger portion, and
a restricting device that restricts attachment and detachment of the container bag to and from the attachment portion when the hanger portion is in the use position.

2 : The blood purification apparatus according to claim 1 , wherein the restricting device is a shielding plate that is fixed to an apparatus main body and that covers and shields the attachment portion only when the hanger portion is in the use position.

3 : The blood purification apparatus according to claim 1 , wherein the restricting device is a shielding plate that is attached to the hanger portion and that is movable between a first position in which the attachment portion is shielded and a second position in which the attachment portion is open, the restricting device being movable from the first position to the second position only when the hanger portion is in the replacement position.

4 : The blood purification apparatus according to claim 1 , further comprising a detecting device detecting that the hanger portion is in the use position, and wherein when, during the blood purification treatment, the detecting device does not detect that the hanger portion is in the use position, it is informed that the hanger portion is not in the use position.

5 : The blood purification apparatus according to claim 1 , further comprising a detecting device detecting that the hanger portion is in the use position, and wherein when, during the blood purification treatment, the detecting device does not detect that the hanger portion is in the use position, control relating to the blood purification treatment is stopped.

6 : The blood purification apparatus according to claim 5 , wherein when, after the control relating to the blood purification treatment is stopped, the detecting device detects that the hanger portion is in the use position, the control relating to the blood purification treatment is resumed.

7 : The blood purification apparatus according to claim 2 , further comprising a detecting device detecting that the hanger portion is in the use position, and wherein when, during the blood purification treatment, the detecting device does not detect that the hanger portion is in the use position, it is informed that the hanger portion is not in the use position.

8 : The blood purification apparatus according to claim 3 , further comprising a detecting device detecting that the hanger portion is in the use position, and wherein when, during the blood purification treatment, the detecting device does not detect that the hanger portion is in the use position, it is informed that the hanger portion is not in the use position.

9 : The blood purification apparatus according to claim 2 , further comprising a detecting device detecting that the hanger portion is in the use position, and wherein when, during the blood purification treatment, the detecting device does not detect that the hanger portion is in the use position, control relating to the blood purification treatment is stopped.

10 : The blood purification apparatus according to claim 3 , further comprising a detecting device detecting that the hanger portion is in the use position, and wherein when, during the blood purification treatment, the detecting device does not detect that the hanger portion is in the use position, control relating to the blood purification treatment is stopped.
