## Abstract

A line mount includes a treatment machine having a housing and one or more magnets or ferromagnetic elements mounted thereon, a line holder having at least one complementary one of magnets and ferromagnetic elements such as to cause the line holder to be attachable magnetically to the housing. The one or more magnets or ferromagnetic elements being numbered and arranged to permit the line holder to be supported thereby in multiple positions and orientations relative to the housing.

## Claims

### Claim 1

A fluid line mount system, comprising:
a medical treatment machine having a housing, the housing having an outer surface and a plurality of first magnets or ferromagnetic elements directly mounted to the outer surface of the housing; and
a line holder having at least two complementary magnets or ferromagnetic elements such that the line holder is attachable magnetically to the housing when the at least two complementary magnets or ferromagnetic elements come into contact with at least two of the plurality of the first magnets or ferromagnetic elements; and,
wherein the plurality of the first magnets or ferromagnetic elements includes at least three magnets or ferromagnetic elements, and
the at least three magnets or ferromagnetic elements have positions that enable the line holder to be magnetically attached to the housing in multiple positions and orientations relative to the housing, each of the multiple positions and orientations corresponding to a respective pair of the first magnets or ferromagnetic elements.

### Claim 2 (depends on 1)

The line mount system of claim 1, wherein the line holder has a longitudinal aspect with an axis that runs between two of the at least three magnets or ferromagnetic elements when the line holder is magnetically attached to the housing.

### Claim 3 (depends on 1)

The line mount system of claim 1, wherein the line holder is a longitudinal member with a mount shaped to engage a fluid line.

### Claim 4 (depends on 1)

The line mount system of claim 1, wherein the line holder is a longitudinal member with a mount shaped to engage a connector of a fluid line.

### Claim 5 (depends on 1)

The line mount system of claim 1, wherein the line holder has multiple slots for receiving multiple fluid lines.

### Claim 6 (depends on 1)

The line mount system of claim 1, wherein the housing has a recess into which one of the at least two complementary magnets or ferromagnetic elements of the line holder fits.

### Claim 7 (depends on 1)

The line mount system according to claim 1, wherein an outermost surface of each of the first magnets or ferromagnetic elements is flush with the outer surface of the housing, resulting in a combined surface that is smooth.

### Claim 8 (depends on 1)

The line mount system of claim 1, wherein the outer surface of the housing has a boss onto which one of the at least two complementary magnets or ferromagnetic elements of the line holder fits.

### Claim 9

A method of using a medical treatment device that supports a fluid line, the method comprising:
providing the medical treatment device, the medical treatment device having a housing that includes a plurality of first magnets or ferromagnetic elements directly mounted on an outer surface of the housing, the plurality including at least three magnets or ferromagnetic elements;
providing a line holder having at least two complementary magnets or ferromagnetic elements such that the line holder is attachable magnetically to the housing when the at least two complementary magnets or ferromagnetic elements come into contact with at least two of the plurality of the first magnets or ferromagnetic elements;
removing the line holder from a first position on the housing, the first position corresponding to the line holder being held by a first pair of the first magnets or ferromagnetic elements; and
attaching the line holder to a second position on the housing, the second position corresponding to a second pair of the first magnets of ferromagnetic elements, different from the first pair, such that the line holder is held in the second position by magnetic attraction between the at least two complementary magnets or ferromagnetic elements and the second pair of the plurality of the first magnets or ferromagnetic elements.

### Claim 10 (depends on 9)

The method of claim 9, wherein the line holder has a longitudinal aspect with an axis that runs between at least two of the first magnets or ferromagnetic elements when the line holder is supported by the housing.

### Claim 11 (depends on 9)

The method of claim 9, wherein the line holder is a longitudinal member with a mount shaped to engage a fluid line.

### Claim 12 (depends on 9)

The method of claim 9, wherein the line holder is a longitudinal member with a mount shaped to engage a connector of a fluid line.

### Claim 13

A method of supporting a medical treatment fluid line of a medical treatment machine, comprising:
providing the medical treatment machine, the medical treatment machine including a housing, the housing having a plurality of first magnets or ferromagnetic elements mounted on an outer surface of the housing, the plurality including at least three magnets or ferromagnetic elements;
providing a line holder having at least two complementary magnets or ferromagnetic elements such that the line holder is attachable magnetically to the housing when the at least two complementary magnets or ferromagnetic elements come into contact with at least two of the plurality of the first magnets or ferromagnetic elements; and
moving the line holder from a first position on the housing to a second position on the housing, the first position corresponding to a first pair of the first magnets or ferromagnetic elements and the second position corresponding to a second pair, different from the first pair, of the first magnets or ferromagnetic elements,
wherein the line holder is held in the first position by a magnetic attraction between the at least two complementary magnets or ferromagnetic elements and the first pair, and
the line holder is held in the second position by a magnetic attraction between the at least two complementary magnets or ferromagnetic elements and the second pair.

### Claim 14 (depends on 13)

The method of claim 13, wherein the one or more plurality of the first magnets or ferromagnetic elements includes at least two magnets or ferromagnetic elements on a first face of the treatment machine housing.

### Claim 15 (depends on 13)

The method of claim 13, wherein the line holder has multiple slots for receiving flexible lines.

### Claim 16 (depends on 13)

The method of claim 13, wherein the housing has a boss or a recess onto or into which one of the at least two complementary magnets or ferromagnetic elements of the line holder fits.
