Abstract

It is an object of the present invention to eliminate mechanical stimulation caused by insertion and extraction of such devices as a bladder endoscope and a urethral catheter into and from a urethra. It is a further object of the present invention to make it possible to simultaneously insert such devices as a bladder endoscope and a urethral catheter into the urethra without causing pain. A urethra protection device of the present invention which can be inserted into a urethra includes a first hollow tube in which a bladder endoscope can be inserted, a second hollow tube in which a urethral catheter can be inserted, and a flange provided on an outer peripheral part of the urethra protection device at a position separated from a forward end thereof which is first inserted into the urethra.

Claims

a first hollow tube in which a bladder endoscope can be inserted;

a second hollow tube in which a urethral catheter can be inserted; and

a flange provided on an outer peripheral part of the urethra protection device at a position separated from a forward end thereof which is first inserted into the urethra.

2. The urethra protection device according to claim 1, wherein the urethra protection device is made of a smooth flexible material.

3. The urethra protection device according to claim 1, wherein the flange is provided at a rear end of the urethra protection device.

4. The urethra protection device according to claim 2, wherein the flange is provided at a rear end of the urethra protection device.

5. The urethra protection device of claim 1, wherein a check valve is provided in the first hollow tube.

6. The urethra protection device of claim 2, wherein a check valve is provided in the first hollow tube.

7. The urethra protection device of claim 3, wherein a check valve is provided in the first hollow tube.

8. The urethra protection device of claim 5, wherein the check valve is provided at a position separated from the forward end of the urethra protection device.

9. The urethra protection device according to claim 5, wherein the check valve is provided at a rear end of the urethra protection device.

10. The urethra protection device according to claim 1, wherein the second hollow tube has a diameter not exceeding that of the first hollow tube.

11. The urethra protection device according to claim 2, wherein the second hollow tube has a diameter not exceeding that of the first hollow tube.

12. The urethra protection device according to claim 3, wherein the second hollow tube has a diameter not exceeding that of the first hollow tube.

13. The urethra protection device according to claim 4, wherein the second hollow tube has a diameter not exceeding that of the first hollow tube.

14. The urethra protection device according to claim 5, wherein the second hollow tube has a diameter not exceeding that of the first hollow tube.

15. The urethra protection device according to claim 6, wherein the second hollow tube has a diameter not exceeding that of the first hollow tube.

16. The urethra protection device according to claim 7, wherein the second hollow tube has a diameter not exceeding that of the first hollow tube.

17. The urethra protection device according to claim 8, wherein the second hollow tube has a diameter not exceeding that of the first hollow tube.

18. The urethra protection device of claim 1, wherein the urethra protection device is configured to be fixed to a body by the flange without use of a balloon.
