Abstract

Here provided are systems and methods for monitoring bladder and/or abdominal pressures, and a bladder function recovery device. In the systems and methods, the bladder pressure can be detected in real time with a bladder pressure detection unit that is communicated with a urinary catheter. In addition, the abdominal pressure can also be obtained in real time according to the corresponding relationship between the bladder pressure and the abdominal pressure. Furthermore, the bladder function recovery device can be used for bladder function recovery for patients in need.

Claims

1. A method for monitoring bladder pressure in a subject, comprising the steps of:

a. providing a bladder pressure detection unit that is connected to a first end opening of a capillary tube, said capillary tube having a second end opening connected to a urinary drainage tube which is in turn connected to a urinary catheter that is placed in the subject, wherein the capillary tube is filled with pressure transmission medium so that the bladder pressure detection unit does not directly contact with urine;

b. detecting the bladder pressure in a continuous manner by the bladder pressure detection unit.

2. The method according to claim 1, further comprising the step of:

determining whether the bladder pressure increases by comparing the detected bladder pressure with the normal pressure of the bladder containing the same volume of pre-stored urine;

wherein an alarm unit is turned on if the bladder pressure increases.

3. The method according to claim 2, further comprising the steps of:

determining whether the bladder pressure is equal to or higher than a preset pressure if the bladder pressure increases; and

determining whether the bladder pressure is valid if the bladder pressure is equal to or higher than the preset pressure;

wherein the bladder pressure is valid if the duration of the bladder pressure is equal to or more than a preset value.

4. The method according to claim 3, further comprising the steps of:

allowing urination through a urination device if the bladder pressure is valid;

determining whether the bladder pressure reaches a preset minimum threshold value during the process of urination;

stopping urination if the bladder pressure reaches a preset minimum threshold value.

5. The method according to claim 1, wherein the bladder pressure detection unit is a low-pressure sensor.

6. A method for monitoring bladder pressure in a subject by detecting the bladder pressure using a bladder pressure monitoring system, wherein the bladder pressure monitoring system comprises:

a bladder pressure detection unit;

a capillary tube having a first and a second end openings with the first end opening of the capillary tube connected to the bladder pressure detection unit, wherein the capillary tube is filled with pressure transmission medium so that the bladder pressure detection unit does not directly contact with urine and the bladder pressure detection unit detects the bladder pressure in a continuous manner;

a urinary drainage tube that is connected to the second end opening of the capillary tube, wherein the drainage tube has a first end opening, a second end opening and one middle opening, with the first end opening of the urinary drainage tube being connected to a urinary catheter, a second end opening of the urinary drainage tube connected to a drainage bag, and the middle opening of the urinary drainage tube connected to the second end opening of the capillary tube;

a first solenoid valve being placed inside the urinary drainage tube at a position between the middle opening and the second end opening of the urinary drainage tube, wherein the first solenoid valve can be switched on or off in controlling the urine flow in the urinary drainage tube; and

a central processing unit that is connected to the bladder pressure detection unit, wherein the central processing unit determines whether the bladder pressure increases and switches on the first solenoid valve for urination when the central processing unit has determined that the bladder pressure increases.
