## Abstract

A catheter fixture 11 for fixing a tubular catheter 1 to skin of a patient is provided with a plate shaped fixture main body 21, a fixing member 41 that is configured separately from the fixture main body, and a pivot connecting shaft 45. The plate shaped fixture main body 21 includes a retention part 22 where a catheter retaining groove 25 is formed, and a pair of winged pieces 23a and 23b. The pivot connecting shaft 45 both connects the fixture main body 21 and the fixing member 41 and acts as the pivot access C1 of the fixing member 41. The fixing member 41 has a pivoting action along a horizontal plane direction of the fixture main body 21 centrally around the pivot connecting shaft 45. When doing so, the catheter retaining groove 25 is covered by the fixing member 41 thereby fixing the catheter 1.

## Claims

### Claim 1

A catheter fixture for fixing a tubular catheter, comprising a plate shaped fixture main body having a pair of winged pieces and a retention part in which a catheter retaining groove is formed, a fixing member configured separately from the fixture main body that can cover the catheter retaining groove, and a pivot connecting shaft that both connects the fixture main body and the fixing member and acts as the pivot axis of the fixing member; wherein the catheter is fixed by pivoting action of the fixing member in relation to the fixture main body along a horizontal plane direction of the fixture main body centrally around the pivot connecting shaft thereby covering the catheter retaining groove with the fixing member, wherein the retention part is pressed by the fixing member upon completion of the pivoting action by the fixing member thereby narrowing the catheter retaining groove.

### Claim 2 (depends on 1)

The catheter fixture according to claim 1, wherein a guide part with a plan view arc shape is provided on the retention part of the fixture main body, and a guided part with a plan view arc shape with the ability to lock with the guide part is provided on a free end side of the fixing member.

### Claim 3 (depends on 1)

The catheter fixture according to claim 1, wherein the pivot connecting shaft is positioned on the fixing member and has a cylindrical shape, and the pivot connecting shaft is axially supported with the ability to pivot within a through hole formed on one of the pair of winged pieces.

### Claim 4 (depends on 1)

The catheter fixture according to claim 1, wherein an upper surface of the retention part of the fixture main body slides in contact with an undersurface of the fixing member during the pivoting action and a raised ridge part is provided on an upper surface of the fixture main body to lift up the fixing member as the fixing member passes over the raised ridge part.

### Claim 5 (depends on 4)

The catheter fixture according to claim 4, wherein a recessed part is provided on the undersurface of the fixing member with the ability to engage with the raised ridge part upon completion of the pivoting action by the fixing member.
