Tutorial for using disposable blood pressure transducer

  Before connecting the blood pressure transducer pipeline, the monitoring device needs to be started.


  After performing the standard disinfection process, unpack the packaging materials, verify that all interfaces are in a safe and closed state, and confirm that the auxiliary components such as the three-way valve are functioning normally. Special note: Avoid over-tightening when assembling the connector. After the sensor fluid path is filled with heparin saline and the bubbles are completely eliminated, all ports of the three-way valve need to be installed with non-hole closure caps.


  For pipeline exhaust operations, two operators are usually required to work together. One of them is responsible for product connection operations in the sterile area, while the assistant is responsible for auxiliary operations such as exhaust of the infusion bag and adjustment of the flow control valve in the non-sterile area.

  Prepare a bag of heparin saline according to the doctor's instructions. The assistant needs to insert the bottle stopper puncture needle of the perfusion device into the infusion bag, with the infusion bag opening facing up, then turn on the flow controller, gently press the infusion bag, and press the sensor perfusion valve with the thumb and index finger at the same time until the air in the perfusion device and all fluid paths is completely exhausted. After closing the flow controller, place the infusion bag in the pressurized infusion bag protective cover and hang it on the infusion pole or infusion stand. 

  Note: Do not pressurize the infusion bag before this. After pressurizing the infusion bag to 300mmHg, reopen the flow controller, point the end of the 30cm short tube upward, press the perfusion valve, and expel all bubbles in the pipeline. Connect it to the pressure measurement catheter while liquid continues to flow out of the outlet of the 30cm short tube. Check again whether there are bubbles in the fluid path. If there are, they need to be removed. Connect a syringe to the other end of the three-way valve and perform blood return and withdrawal to verify the position and functional status of the arterial catheter.


  Regarding the connection and zeroing of the monitoring device, it is recommended to place the blood pressure transducer at the intersection of the mid-axillary line and the anterior edge of the second rib, ensuring that it is level with the heart zero point. Point the "closed" end of the three-way valve close to the transducer to the patient side, remove the red perforated closure cap, and perform zero calibration according to the user manual of the monitoring device. After the zeroing of the monitoring device is completed, point the "closed" end to the atmosphere side, and install the white non-perforated closure cap after disinfection. After the zeroing operation is confirmed to be correct, observe the pressure waveform and value displayed on the monitoring device.


  Note: If the zeroing operation fails, the sensor should be replaced and zeroing should be performed again; if the zeroing is still unsuccessful, it is necessary to check whether the cable connection, monitoring device, etc. are normal. Use heparin saline to flush the fluid path and ensure that there are no bubbles remaining in the fluid path.
