Abstract

A medical tubing member is used in a medical system that allows fluid to flow between an inside and outside of a subject. The medical tubing member includes a first tubing member and a second tubing member. The first tubing member is configured to be arranged outside the subject and is configured to be connected to a first line disposed in an endoscope. The first tubing member is configured to supply the fluid from the outside of the subject to the inside of the subject. The second tubing member is configured to be arranged outside the subject and configured to be connected to a second tubular line disposed in the endoscope. The second tubing member is configured to discharge the fluid from the inside of the subject to the outside of the subject. The second tubing member is disposed inside the first tubing member.

First claim

What is claimed is:

1 . A medical tubing member for use in a medical system that allows fluid to flow between an inside and outside of a subject, comprising:
a first tubing member configured to be arranged outside the subject, and configured to be connected to a first tubular line disposed in an endoscope, which is to be inserted into the subject, and to supply the fluid from the outside of the subject to the inside of the subject via the endoscope; and a second tubing member configured to be arranged outside the subject, and configured to be connected to a second tubular line disposed in the endoscope and to discharge the fluid from the inside of the subject to the outside of the subject via the endoscope; wherein the second tubing member is disposed inside the first tubing member.

2 . The medical tubing member of claim 1 , further comprising:
a connector configured to permit connection of the first tubing member to the first tubular line and also connection of the second tubing member to the second tubular line.

3 . The medical tubing member of claim 1 , wherein
the first tubing member is at an end thereof in communication with a device that supplies the fluid to the inside of the subject, and also is at an opposite end thereof in communication with the first tubular line disposed in the endoscope to be inserted into the subject, and the second tubing member is at an end thereof in communication with a device that discharges the fluid from the inside of the subject, and also is at an opposite end thereof in communication with the second tubular line disposed in the endoscope to be inserted into the subject.

4 . The medical tubing member of claim 3 , wherein
the medical system includes a circulation device having a pump configured to allow circulation of the fluid between the inside and outside of the subject via the endoscope, the first tubing member is configured to form a part of a flow passage through which the fluid is supplied to the inside of the subject by the pump of the circulation device, and the second tubing member is configured to form a part of a flow passage through which the fluid is discharged to the outside of the subject by the pump of the circulation device.

5 . The medical tubing member of claim 1 , wherein the first tubing member and the second tubing member are configured in a state that no wall is used in common.

6 . The medical tubing member of claim 5 , further comprising:
a support member configured to support the second tubing member inside the first tubing member so that the second tubing member is arranged at a preset position inside the first tubing member.

7 . The medical tubing member of claim 6 , wherein the support member is configured to arrange the second tubing member at a position inside the first tubing member where the first tubing member and second tubing member have coinciding central axes.

8 . The medical tubing member of claim 6 , wherein the support member is formed integrally on a part of an outer circumferential wall of the second tubing member, but is formed discretely from an inner circumferential wall of the first tubing member.

9 . The medical tubing member of claim 6 , wherein the support member configured to be formed so that the first tubing member and the second tubing member are integrally connected together at parts of inner circumferential wall of the first tubing member and outer circumferential wall of the second tubing member.

10 . The medical tubing member of claim 1 , wherein the first tubing member and second tubing member are each formed with a material having flexibility, and are configured to be formed so that they have mutually-different ultimate strengths to a stress applied externally.

11 . The medical tubing member of claim 10 , wherein the first tubing member is lower in the ultimate strength to the stress than the second tubing member.

12 . The medical tubing member of claim 10 , wherein the second tubing member is lower in the ultimate strength to the stress than the first tubing member.

13 . The medical tubing member of claim 1 , wherein the second tubing member is formed helically.

14 . The medical tubing member of claim 1 , wherein the second tubing member and first tubing member are configured so that the second tubing member allows solid soil to pass therethrough and the solid soil has a maximum width greater than that of solid soil which the first tubing member allows to pass therethrough.

15 . A medical tubing member for use in a medical system that allows fluid to flow between an inside and outside of a subject, comprising:
a first tubing member configured to be arranged outside the subject, and configured to supply the fluid from the outside of the subject to the inside of the subject; a second tubing member configured to be arranged outside the subject, and configured to discharge the fluid from the inside of the subject to the outside of the subject; a first connecting member configured to connect the first tubing member to a first trocar to be pierced through a body wall of the subject; and a second connecting member configured to connect the second tubing member to a second trocar to be pierced through the body wall of the subject, wherein the second tubing member is disposed inside the first tubing member.

16 . A medical system comprising:
an endoscope, a light source, a video processor, a circulating tubing member, and a circulation device all of which configured to be attached to one another to perform treatment of an affected tissue of a body while controlling circulation of fluid between respective inside and outside of the body without and avoiding an oversupply of the fluid into the body during the treatment; a medical tubing member for use in the medical system that permits fluid to flow between the respective inside and outside of the body having
a first tubing member configured to be arranged outside the body, and configured to be connected to a first tubular line disposed in the endoscope, which is to be inserted into the body, and to supply the fluid from the outside of the body to the inside of the body via the endoscope, and
a second tubing member configured to be arranged outside the body, and configured to be connected to a second tubular line disposed in the endoscope and to discharge the fluid from the inside of the body to the outside of the body via the endoscope;
wherein the second tubing member is disposed inside the first tubing member.
