The operation process of B. Braun CRRT machine
The operation process of B. Braun CRRT machine
1. Plug in the power, turn on the machine power and enter "SELF
TEST (power-on self-test)" working status, the working status is displayed in the upper right corner of the screen. (At this time, make sure nothing is installed on the machine. If it is installed, remove it all).
2. The machine automatically performs the following three power-on self-tests. If the shutdown time is not long enough, items (2) and (3) will not appear. Ongoing self-test items, such as "ROM
TEST" are displayed on the line below the working status, and the corresponding self-test process is displayed on the line below the self-test items.
(1) "ROM TEST (Program Self-Test)": That is, software verification (CRC) is performed, and all 6 indicators on the panel will light up.
(2) "DISPLAY TEST (display self-test)": If it is correct, press the [EQ] key to confirm, and the alarm sound will sound for 2 seconds.
(3) "EMPTY LOAD CELL TEST (called no-load self-test)": If it is no-load and the value is within 60 and -60 grams, press the [EQ] key to confirm.
3. After the power-on self-test is completed, the machine automatically enters the "THERAPY SELETION" working state.
4. Select the treatment type and select CONTINUOUS.
5. Select the treatment item, select CVVH, and press the [EQ] key to confirm. The machine enters the "PREPARATION" working state.
6. Skip the hardware self-test: press and hold V, BE, ▲ at the same time, and press the [EQ] key to confirm.
7. Install the pipeline
[1], install on the scale: (1) replacement fluid (conventional formula: NS3000ml 5GS1000ml calcium chloride 1g 25 magnesium sulfate
3.2ml).
(2), Ultrafiltrate collection bag.
[2]. Install the hemofilter with the vein end facing up.
[3]. Install the arterial line (red). Connects to saline bag, PA, blood pump, heparin, PBE, hemofilter.
[4], Install the police sales official road (blue). Connects to hemofilter, PV, venous air monitor, venous clamp.
[5]. Install the rehydration line (green). Connects to replacement fluid bag, replacement air monitor, PD1, heater, arterial line (anterior replacement) or venous line (posterior replacement).
[6]. Install ultrafiltration pipeline (yellow). Connect to the hemofilter (venous end), blood leakage monitor, PD2, ultrafiltration pump, and ultrafiltrate collection bag.
8. Open all pipeline clamps and pre-flush/self-check.
9. Blacken PRIMING to start pre-flush. Follow the machine prompts to turn on the blood pump, and the machine will automatically perform pre-flush/self-test. After the self-inspection is completed, the machine automatically flushes (RINSING) the pipeline. After flushing is completed, the machine will sound a music prompt and display "READY
FOR THERAPY" in the upper right corner of the screen.
10. Parameters can be set during pre-flushing/self-test/flushing. Blacken PARAMETER
SETTING to enter the parameter setting screen. All parameters of the machine have been automatically preset to the default values. If there are no special requirements, you do not need to modify them. The main settings are SUBSTITUTION FLOW (displacement fluid flow), UF
RATE (net ultrafiltration rate) and CYCLE TIME ( treatment time) etc.
(1). Press the ▲ or ▼ key to move the cursor to the data to be modified, and the adjustable range of the data will be displayed in the upper right corner of the screen.
(2) Press the Enter key once and the data will be displayed in reverse video, indicating that the data is ready to be modified.
(3). Press the ▲ or ▼ key to adjust the data to the desired value.
(4). Press the Enter key again to indicate that the data has been modified.
If necessary, press the EQ button to confirm and the data will appear normally.
(5), repeat (1)-(4), set other parameters.
(6). Press the Enter key three times quickly after (4) to exit the parameter setting screen.
11. Blacken ENTER
THERAPY (enter treatment), and press the EQ key to confirm, and the machine enters the treatment working state. First, waiting to connect to the patient (STANDBY). The machine performs blood leakage zero point calibration. If the pipeline in the blood leakage monitor is filled with liquid and there is no blood or air, press the EQ key to confirm.
12. Connect with patients.
(1), stop the blood pump;
(2), connect the arterial line to the patient;
(3), turn on the blood pump, with 50 -60ml/min blood flow to induce blood;
(4), check whether the arterial pressure is within the allowable range;
(5), when the venous line can be connected to the patient , stop the blood pump, connect the venous line to the patient;
(6), turn on the blood pump, and adjust the blood flow to an appropriate value according to the patient's condition;
(7), check Arterial pressure and venous pressure displayed on the screen.
13. After 2-3 minutes of blood circulation, if there is no alarm, black THERAPY to enter the treatment selection (THERAPY RUNNING), and the treatment timer starts.
14. Pay attention to observing various parameters and eliminate alarms. Blacken the TOTALS OVERVIEW (total total display) to view each total. Black PRESSURE
OVERVIEW (total pressure display) allows you to view the filter pressure diagram.
15. Change bags. Changing the total weight of the scale without notifying the machine (hanging a replacement fluid bag on the scale, removing anything from the scale, touching items on the scale) will cause an alarm. When it is necessary to change the bag:
(1), blacken the BAG CHANGE (change the bag);
(2), change the bag;
(3), Black THERAPY.
16. End of treatment
(1) Blacken END OF THERAPY, and the machine enters the end of treatment state;
(2) Stop the blood pump. Disconnect the patient's arterial line and connect the saline bag, and turn on the blood pump;
(3) Wait until enough saline is sucked in, then remove the saline bag;
(4) Return the blood, When there is an air alarm, the blood pump will automatically stop, silence, and blacken SAD EXCLUSION to disable the air alarm, and press the EQ key to confirm;
(5) Turn on the blood pump, and it will automatically stop after running for a few seconds, and the intravenous tube The blood or saline in the path just returns to the patient;
(6) Remove the intravenous line from the patient and remove all consumables from the machine. Dispose of all used materials according to regulations;
(7) Blacken NEW THERAPY and return to the treatment selection working state.
17. Select a new treatment item or shut down.
