The filling interface 4 is in communication with the other end of the delivery channel 14. The flushing interface 5 is fixedly arranged on the outer side wall of the nephrostomy tube body 1 and is arranged adjacent to the filling interface 4. The flushing interface 5 is in communication with the flushing channel 15.

[0044] Specifically, the improved nephrostomy tube comprises a nephrostomy tube body 1, a blood monitoring structure 2, a balloon 3, a filling interface 4 and a flushing interface 5. The nephrostomy tube body 1 is provided with a main channel 13 penetrating in the direction from an insertion end 11 to an external end 12. The main channel 13 is used for draining urine and can be connected with an external drainage bag. The nephrostomy tube body 1 is further provided with a delivery channel 14 and a flushing channel 15. The delivery channel 14 is used for delivering gas or liquid to the balloon 3 to fix the nephrostomy tube. The flushing channel 15 is used for delivering flushing liquid to the kidney of a patient. The blood monitoring structure 2 is arranged on the nephrostomy tube body 1 and is used for monitoring the color of the drained urine. The balloon 3 is fixedly arranged on the outer side wall of the nephrostomy tube body 1 and is arranged close to the insertion end 11. One end of the delivery channel 14 is in communication with the balloon 3. The filling interface 4 is fixedly arranged on the outer side wall of the nephrostomy tube body 1 and is arranged close to the external end 12. The filling interface 4 is in communication with the other end of the delivery channel 14. The flushing interface 5 is fixedly arranged on the outer side wall of the nephrostomy tube body 1 and is arranged adjacent to the filling interface 4. The flushing interface 5 is in communication with the flushing channel 15. The nephrostomy tube can monitor the bleeding condition of the kidney to avoid delay of the disease condition. Meanwhile, the flushing channel 15 is arranged to facilitate the flushing of the blocked tube.

[0045] In one possible implementation, as shown in Figure 2As shown, the main channel 13, the delivery channel 14 and the flushing channel 15 are not communicated with each other. The main channel 13 is used to communicate the kidney with the drainage bag, the delivery channel 14 is used to communicate the filling interface 4 with the balloon 3, and the flushing channel 15 is used to communicate the flushing interface 5 with the kidney. The flushing channel 15 is provided with a flushing port at the end away from the flushing interface 5, which is used to output the flushing liquid. The flushing port is located on the outer side wall of the nephrostomy tube body 1. The main channel 13, the delivery channel 14 and the flushing channel 15 are not communicated with each other, so that the drainage path of the main channel 13, the liquid inlet section flushing path of the flushing channel 15 and the inflation path / liquid filling path of the delivery channel 14 are independent of each other and do not interfere with each other.

[0046] In a possible implementation, the other end of the flushing channel 15 is provided with a one-way valve 6 to avoid reverse flow of liquid in the flushing channel 15, i.e. the flushing liquid injected from the flushing interface 5 will not flow back into the flushing channel 15 in reverse after entering the kidney through the flushing port, but will flow out from the main channel 13, so as to separate the liquid inlet section flushing path and the liquid outlet section path of the flushing process to prevent the blood clots in the tube from flowing back to the kidney to cause complications such as retrograde infection and improve the safety of flushing.

[0047] In a possible implementation, the flushing port at the other end of the flushing channel 15 is arranged at a distance of 1 cm from the balloon 3. This arrangement close to the balloon 3 can facilitate the regular flushing during the interventional operation or after the operation, effectively remove the blood, debris or other residues in the tube, prevent the tube from being blocked, and ensure the smoothness of the treatment channel. The distance of 1 cm can avoid the influence of the distance on the liquid outlet direction of the flushing liquid.

[0048] In a possible implementation, the filling interface 4 is detachably connected with the external injector nipple, and the flushing interface 5 is detachably connected with the external injector nipple. The filling interface 4 and the flushing interface 5 are adapted to the external injector nipple. The detachable connection can be screwing or clamping. The filling interface 4 can also be provided with a one-way valve 6 or an end cap to seal the gas or liquid filled in the balloon 3.

[0049] In a possible implementation, the blood monitoring structure 2 is arranged between the insertion end 11 and the filling interface 4 and close to the filling interface 4. The insertion end 11 of the nephrostomy tube body 1 needs to be inserted into the patient's body, while the external end 12, the filling interface 4 and the flushing interface 5 are located outside the patient's body. The blood monitoring structure 2 also needs to be located outside the patient's body to facilitate monitoring, and thus is arranged close to the filling interface 4.

[0050] The nephrostomy tube body 1, the balloon 3, the filling interface 4 and the flushing interface 5 of the present application are integrally formed.

[0051] In a possible implementation, the blood monitoring structure 2 is detachably connected to the outer side wall of the renal fistula tube body 1, and the monitoring direction of the blood monitoring structure 2 points to the main channel 13 of the renal fistula tube body 1, so as to facilitate monitoring of the color of the drained urine in the main channel 13 of the renal fistula tube body 1 by the blood monitoring structure 2, thereby being able to timely know the renal hemorrhage condition of the patient. The detachable connection mode of the blood monitoring structure 2 and the renal fistula tube body 1 can be a pasting type, that is, the blood monitoring structure 2 can be pasted on the renal fistula tube body 1, or a clamping type, that is, a clamping groove is formed on the outer side wall of the renal fistula tube body 1, and a clamping protrusion is arranged on the blood monitoring structure 2, and the detachable connection is realized by clamping the clamping groove and the clamping protrusion.

[0052] In a possible implementation, the blood monitoring structure 2 comprises a blood sensor and an illuminating lamp, and the blood sensor and the illuminating lamp are integrated to form a micro blood monitoring structure 2. The blood sensor can be in communication connection with an external buzzer, or the blood monitoring structure 2 is provided with a micro buzzer.

[0053] Further, the blood sensor can be a micro color sensor or a micro camera, which is used to acquire a color image in the main channel 13 of the renal fistula tube body 1 in real time, and the illuminating lamp is a micro LED lamp, which is used to illuminate the blood sensor in a dark environment.

[0054] Specifically, the blood monitoring structure 2 further comprises a micro power supply, which is electrically connected with the blood sensor and the illuminating lamp respectively, and is used to supply power for the blood sensor and the illuminating lamp.

[0055] Specifically, the blood monitoring structure 2 can further be provided with a control chip, which is electrically connected with the blood sensor, the illuminating lamp and the power supply. On the one hand, when the blood monitoring structure 2 does not provide the buzzer, the control chip can be in communication connection with the external buzzer, and then when the blood sensor monitors that the color of the drainage in the main channel 13 of the renal fistula tube body 1 becomes red, that is, renal hemorrhage occurs, a signal can be sent to the external buzzer by wireless communication technology to give a prompt; on the other hand, the blood monitoring structure 2 can further be provided with a micro buzzer, the control chip is electrically connected with the micro buzzer, and the micro buzzer, the control chip, the blood sensor and the illuminating lamp are integrated, and then when the blood sensor monitors that the color of the drainage in the main channel 13 of the renal fistula tube body 1 becomes red, that is, renal hemorrhage occurs, the buzzer can directly give a prompt. The signal transmission process between the control chip and the buzzer can be realized by using the existing technology, which will not be described here.
