[0002] Severely ill patients are in critical condition and often require hemodynamic monitoring to guide clinical treatment. During the monitoring process, a disposable pressure measurement kit with a transducer must be used. The transducer needs to be kept at the same level as the right atrium during the monitoring process. Generally, it is fixed to the patient's upper arm with tape, or fixed to the bed board with tape to ensure that the sensor plane is flush with the right atrium, which is more troublesome. There is also a risk of device-related pressure injury when the tape is directly fixed to the skin of the upper arm.

[0028] The device solves the problem that the transducer fixing device has a single fixing method, poor fixing effect, easy displacement, pulling or entanglement of the connecting line, and pressure damage to the connecting line by setting the fixing component 3 and the metal hose 8.
