Cable and medical hollow tube
A cable includes a sheath, and a coating film covering a circumference of the sheath. The coating film adheres to the sheath. The static friction coefficient of a surface of the coating film is smaller than the static friction coefficient of a surface of the sheath. The adhesion strength between the sheath and the coating film is 0.30 MPa or more.
1. A cable, comprising:
a sheath; and
a coating film covering a circumference of the sheath, the coating film adhering to the sheath,
wherein a static friction coefficient of a surface of the coating film is 0.5 or less,
wherein an adhesion strength between the sheath and the coating film is 0.30 MPa or more, and
wherein a parent material of the coating film is produced by curing an addition reaction type coating agent.
2. The cable according to claim 1 , wherein the coating film comprises fine particles dispersed in a parent material.
3. The cable according to claim 2 , wherein the fine particles include any one or a plurality of silicone resin fine particles, silicone rubber fine particles, or silica fine particles.
4. The cable according to claim 2 , wherein the fine particles have a higher hardness than that of the parent material.
5. The cable according to claim 2 , wherein the fine particles comprise an average particle diameter of 1 μm or more and 10 μm or less.
6. The cable according to claim 1 , wherein the coating film comprises a thickness of 3 μm or more and 100 μm or less.
7. The cable according to claim 1 , wherein the sheath is made of silicone rubber.
8. The cable according to claim 1 , wherein the cable is a probe cable, which is connectable to a medical device.
9. The cable according to claim 1 , wherein a roughness of an uneven shape of the surface of the coating film is higher than a roughness of an uneven shape of the surface of the sheath.
10. The cable according to claim 1 , further comprising:
a protective member bonded around the coating film,
wherein a static friction coefficient of a surface of the coating film is smaller than a static friction coefficient of a surface of the sheath, and
wherein an adhesion strength between the sheath and the coating film is equal to a bonding strength between the coating film and the protective member, or
greater than the bonding strength between the coating film and the protective member.
11. The cable according to claim 1 , wherein the coating film is an addition reaction type silicone rubber.
12. The cable according to claim 11 , wherein the coating film is substantially void-free in an interface between the coating film and the sheath.
