[0002] Invasive arterial blood pressure monitoring is a method of directly measuring blood pressure by inserting an arterial catheter into an artery. The components of an arterial pressure monitoring system include an arterial catheter, an extension tube, a three-way switch, a blood sampling device, a pressure sensor, a continuous flushing device, and wires connecting to a bedside monitor and an oscilloscope. Among them, the pressure sensor is used to measure important parameters such as blood pressure and pulse wave in the heart and vascular system, and is an essential medical device in medical places such as intensive care units, operating rooms, and emergency departments.

[0003] When fixing a pressure sensor on a patient's body surface in the prior art, ordinary tape is usually used to stick the pressure sensor on the body surface of the patient's upper arm. However, ordinary tape may cause medical adhesive-related skin damage to edematous and thin skin, and pain will also be caused when tearing the tape later. Moreover, after sticking the pressure sensor on the body surface of the patient's upper arm with ordinary tape, the catheter connected to both ends of the pressure sensor is in contact with the skin, resulting in easy occurrence of large-angle bending at the joint of the pressure sensor and the catheter, affecting the use of the pressure sensor.

A protection assembly for preventing the joints of the pressure sensor 101 and the conduit 102 from being bent too much is provided on the gasket 201.

[0031] In addition, the constraint component includes a positioning belt 204 fixed to the first cuff 202 and the second cuff 203.
