Abstract

A liquid feeding pump for feeding liquid in a liquid feeding tube, the liquid feeding pump including: a mounting portion to which a first clip member mounted to the liquid feeding tube is mountable; an adapter detachably attachable to the mounting portion; and a detection unit configured to detect mounting of the first clip member to the mounting portion, wherein: the adapter has a shape that disables detection by the detection unit of mounting of the first clip member by the detection unit and enables detection by the detection unit of mounting of a second clip member having a shape different from a shape of the first clip member.

Claims (37)

1 . A liquid feeding pump for feeding liquid in a liquid feeding tube, the liquid feeding pump comprising:

a mounting portion to which a first clip member mounted to the liquid feeding tube is mountable;

an adapter detachably attachable to the mounting portion; and

a detection unit configured to detect mounting of the first clip member to the mounting portion, wherein:

the adapter has a shape that disables detection by the detection unit of mounting of the first clip member by the detection unit and enables detection by the detection unit of mounting of a second clip member having a shape different from a shape of the first clip member.

2 . The liquid feeding pump according to claim 1 , wherein:

the adapter defines an insertion space formed to disable insertion of the first clip member and enable insertion of the second clip member.

3 . The liquid feeding pump according to claim 2 , wherein:

the adapter comprises:

a cover member that defines the insertion space, and

a detection assisting member that is detected by the detection unit by being pressed and moved or deformed by the second clip member inserted into the insertion space.

4 . A system comprising:

the liquid feeding pump according to claim 1 ; and

the liquid feeding tube, which is an infusion tube configured to feed an infusion solution; wherein:

the first clip member is mounted to the infusion tube.

5 . A system comprising:

the liquid feeding pump according to claim 1 ; and

a nutrient tube configured to feed a nutrient; wherein:

the second clip member is mounted to the nutrient tube.

6 . The liquid feeding pump according to claim 1 , comprising:

a main body portion configured to control feeding of the liquid; and

a door portion pivotably connected to the main body portion; wherein:

the door portion and the main body portion are configured to sandwich the liquid feeding tube when the door portion is closed with respect to the main body portion; and

when the first clip member is mounted to the mounting portion in a state in which the door portion is open with respect to the main body portion, the mounting portion is configured to close the liquid feeding tube to which the first clip member is mounted.

7 . The liquid feeding pump according to claim 6 , wherein:

the mounting portion is configured such that, after the first clip member is mounted to the mounting portion and the door portion is closed with respect to the main body portion, closing of the liquid feeding tube is released.

8 . An adapter for use with a liquid feeding pump, the liquid feeding pump comprising a mounting portion to which a first clip member mounted to a liquid feeding tube is mountable, and a detection unit that detects mounting of the first clip member to the mounting portion, the adapter having:

a shape that disables detection of mounting of the first clip member by the detection unit and enables detection of mounting of a second clip member having a shape different from a shape of the first clip member by the detection unit, wherein:

the adapter is configured to be detachably attached to the mounting portion.

9 . The adapter according to claim 8 , wherein the adapter defines an insertion space formed to disable insertion of the first clip member and enable insertion of the second clip member.

10 . The adapter according to claim 9 , comprising:

a cover member that defines the insertion space; and

a detection assisting member that is detected by the detection unit by being pressed and moved or deformed by the second clip member inserted into the insertion space.

11 . A liquid feeding set for use in a liquid feeding pump, the liquid feeding set comprising:

a liquid feeding tube; and

a clip member attached to the liquid feeding tube, the clip member comprising a hook configured to engage with a cover member of an adapter, wherein:

the clip member has a shape that cannot be mounted to a mounting portion of the liquid feeding pump and can be mounted to the liquid feeding pump only via the adapter attached to the mounting portion.
