Preparation before operation

(1) Patient preparation

1. Register basic information of the patient;

2. Before intubation, the patient evacuates urine and feces

3. Explain the entire operation process to the patient, obtain cooperation, and reduce discomfort.

(2) Instrument preparation

1, open the computer and anorectal pressure measurement software, prepare the tape;

2. Check that the water level of the water tank of the instrument should be no less than 1\4 position. Otherwise, please add distilled water in the water tank to be no more than 3\4 position;

3, the treatment bed is prepared with white pad, gauze and toilet paper;

4, with good gloves, connect the catheter to the pressure sensor on the instrument, the serial number of the catheter and the pressure sensor on the electronic amplifier are numbered 1-1, 2, 2, 3, ..., 8-8, one-to-one correspondence;

5. Click the “Open Water Valve” and “One Button Flush Capsule” buttons on the main interface of the operation. At this time, drain the gas in the tube and place the tube horizontally until the water in the 8 channels is even. Click “Restore normal pressure”.

(3) Operation process

1. Select the patient on the computer;

2. Let the patient lie in bed, position the body, and bend the knee on the right side;

3. Select the patient information to be checked in the main operation interface, and select the correct program (biological feedback) in the operation navigation, select the appropriate pressure measuring catheter, and then click to enter the “Start Pressure Measurement” button;

4. Select the training mode and select the patient's corresponding mode according to the patient's condition;

5. The pressure measuring catheter is lubricated and inserted from the anus. The insertion length is 8th in the anal canal. The catheter can be 8.5cm in the anus. The 30 seconds rectal resting pressure is recorded, the catheter is fixed, and covered with a blanket. Protect patient privacy.

Adjust the baseline pressure: Place the catheter horizontally at the height of the patient's anus. Click the “Adjust Baseline” button for about 5 seconds. The system can adjust the 8-lead pressure curve to around 0mmHg. If the deviation is large, please adjust it again.

  (Recommendation: You can slowly pull the catheter while observing the curve on the computer. When the 8th guide leaves the anal canal, stop pulling and return 0.5cm;)

 6. The patient is relaxed for 2-5 minutes to allow the patient to adapt to the pressure measuring catheter;

 7. Record the rectal and anal sphincter resting pressure: the patient recorded at rest for about 30 seconds, and calculated the average value for the rectal and anal sphincter resting pressure.

(2) Instruct the patient to do the action and ask the patient's feelings:

Let the patient do the action according to the computer prompts, increase the abdominal pressure when the anus is relaxed, and repeatedly train this action, about 30 minutes or so;

Post-operational treatment: exit the pressure measurement software, catheter cleaning and disinfection
