The alarm 29 is in communication connection with the controller 24, and when the time that the real-time pressure value is greater than or less than the preset pressure value exceeds the preset time, the alarm 29 gives an alarm to warn the medical staff to check the pressure monitoring device 2 and the state of the patient as soon as possible, so that the safety of the wearing process of the patient is ensured.
For example, the preset time is five minutes, and if the real-time pressure value is greater than the preset pressure value for more than five minutes, the real-time pressure value cannot be reduced, the alarm 29 is controlled to give an alarm, so that the patient is prevented from being subjected to the greater pressure for a long time. Similarly, if the real-time pressure value is less than the preset pressure value for more than five minutes, the real-time pressure value cannot be raised, and the alarm 29 also gives an alarm, so that the normal use of the cover 1 is prevented from being affected due to too small pressure for a long time. Moreover, if the patient removes the cover 1 from the way without the consent of the medical staff, the operation of the pressure control mechanism 22 will not cause the increase of the real-time pressure value, and after more than five minutes, the alarm 29 will also give an alarm, thereby playing a role in prompting the medical staff to put the cover 1 on the patient again as soon as possible.
In addition, the alarm 29 can also be arranged in a duty room of a medical staff or carried by the medical staff, and the alarm 29 is connected to the controller 24 through wireless communication in a mode of 5G, WIFI and the like, so that the medical staff can quickly obtain a warning signal.
