[0030] The use method of the measuring device is as follows:

[0031] Hang the scale 12 on one of the fixed hanging racks 9, then fix the glass tube 4 by using the mounting groove 14 and the fixing clamp 6, connect the infusion tube joint 15 and the Y-shaped joint 3 by using the connecting tube 16, and fix the infusion tube joint 15 and the Y-shaped joint 3 by using the two positioning grooves 13, and then fix the fixed hanging rack 9 and the protective cover 11 after the elastic protrusion 22 is clamped with the clamping hole;

[0032] Warm the infusion bottle 7 to 35-37℃, paste the scale mark on the bottle, insert the infusion tube 5, exhaust and hang the infusion tube 5 on the other fixed hanging rack 9;

[0033] Make the glass tube 4 and the infusion tube 5 communicate by using the infusion tube joint 15 and the connecting tube 16 through the Y-shaped joint 3;

[0034] Ask the patient to empty the bladder as much as possible, and take a supine position or a sitting position;

[0035] Fix the catheter 2 on the patient, connect the catheter 2 with the Y joint 3, and make sure the connection is smooth;

[0036] Adjust the height of the measuring device so that the zero point of the glass tube 4 (a small amount of physiological saline is first filled into the glass tube to adjust the zero point) is at the same level as the pubic symphysis of the patient;

[0037] Turn on the regulator on the infusion tube 5 to infuse physiological saline into the bladder at an appropriate speed;

[0038] Observe the fluctuation of the water column in the glass tube 4 (represented by cmH2O) for each certain volume of liquid;

[0039] Record the change in pressure corresponding to the change in volume (the value of the fluctuation of the water column for every 50ml of liquid);

[0040] Stop the measurement when the water column in the glass tube 4 rises above 40cm or there is urine leakage from the urethral orifice;

[0041] Remove the measuring device, empty the bladder by drainage, remove the catheter 2, and record the amount of catheterized urine for analysis.

[0042] 1. If a balloon catheter is used, do not inject water into the balloon, as this may affect the pressure measurement results.

[0043] 2. The infusion speed has an impact on the measurement results. It is best to use an infusion pump to drip the liquid into the bladder at a uniform speed. Generally, a conventional infusion speed of 20-30ml / min is used, but if the bladder is overactive, the dripping speed can be slowed down to less than 10ml / min. If the water column rises rapidly, the measurement does not necessarily have to be stopped at this time; the dripping speed can be slowed down first, and then observation can be made.

[0044] 3. The patient is awake and has not taken sedatives or drugs that affect bladder function.

[0045] 4. Measure blood pressure before, during, and after the measurement.

[0046] 5. Ask the patient about their feelings, such as the first sensation of bladder fullness, the first sensation of urination, strong urination, and pain, and record the corresponding bladder volume.

[0047] 6. Ask the patient to cough before, during, and after the measurement to test whether the tubes are unobstructed and whether the water column fluctuation is sensitive.

[0048] 7. If the urine routine shows "++" or more white blood cells and red blood cells, the test should be used with caution, and it should not be used if the patient has systemic symptoms.

[0049] 1. High-compliance bladder: As the bladder capacity increases, the pressure always remains at a low level. When the normal bladder capacity is reached, the pressure still does not increase, and the bladder capacity is higher than normal, that is, generally greater than 500ml.

[0050] 2. Low-compliance bladder: As the bladder capacity increases, the pressure in the bladder increases significantly, and the bladder capacity is significantly lower than normal (generally less than 200 ml).

[0051] The normal intravesical pressure during filling is 10 to 15 cm of water. When the intravesical pressure exceeds 40 cm of water, the risk of upper urinary tract dysfunction, such as ureteral reflux and hydronephrosis, increases significantly.

[0052] Therefore, 40cm of water is considered the upper limit of safe pressure. The bladder capacity at safe pressure is the safe capacity. Only by storing and urinating at safe pressure can the function of the upper urinary tract be protected.

[0053] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
