This creation relates to a physiological value detection system, and more particularly to a wireless detection system for sensing changes in the physiological value of an organ in an implantable organism.

According to the neurosurgical patients, the intracranial pressure rises due to severe impact on the head or brain tumors. Even after the patient has undergone craniotomy, it may cause blood clots or local swelling due to the affected part. The intracranial pressure continues to rise, accompanied by secondary brain injury (SBI), which is life-threatening. Therefore, in the neurosurgical intensive care unit, in severe cases of severe brain impact or craniotomy, the intracranial pressure detection probe is placed in the manner of a Burr hole to protect and monitor the patient's life state. Important indicators.

The pressure waveform is presented on the screen that is transmitted to a physiological monitor (not shown). That is, the entire pressure detection system is applied to the probes 11, 12 of the patient's brain.
