At present, the old work and the old business in China still face the problems that the population of the old is continuously increased and the aging degree is continuously deepened, the health condition of the old is also optimistic, and the population of the disabled and semi-disabled old is large. Especially for the disabled or semi-disabled old people who cannot leave the bed, the family children need to work, so that the old people cannot be noticed at any time, and the expense required for asking the worker is also intolerable for the common families. In recent years, a plurality of social problems of serious damage and death of the old caused by the fact that the old cannot be found to trip, fall or fall down to the bed in time appear in the society. In addition, for patients with tuberculosis complicated with hemoptysis, patients with spine fracture, patients with cerebral hemorrhage, etc. who need absolute bed rest, they may not or not completely comply with the orders but change the bed state required by the doctor by themselves or even leave the bed by themselves. Because family members, nursing staff, nurses or doctors and the like cannot monitor the actual bedridden state of the patient at any time, the patient requiring the bedridden state can fall down, accidentally fall down or other activities to cause serious physical injury, and if the patient cannot be found out in time and can be rescued in time, the life safety of the patient can be endangered.
Many monitoring commodities are used for monitoring the condition of a patient in the market, such as acquiring the activity condition of the patient by adopting video monitoring, but the video monitoring range is extremely limited and the effect is poor, if the patient is in a critical condition and is out of the video monitoring range, the patient can be not timely rescued, and the life safety of the patient can be influenced; the utility model of publication No. CN216352724U provides a patient gets off-bed alarm device, which is arranged on a railing at the side of a sickbed, a button pressure detection module is used for collecting stress information of buttons in a railing adjusting mechanism on the railing at the side of the sickbed, a rotation detection module is used for collecting rotation information of the railing at the side of the sickbed, a control module is used for determining that the railing is put down according to the stress information and the rotation information, and a communication module is used for sending alarm information to a nurse center to inform medical staff of timely reaction and treatment. The utility model with publication number CN107170198B discloses a bed leaving detection alarm device, which comprises: the device comprises a control module, an information acquisition unit, a main node and a network node, wherein the states of people to be detected which can be detected by the device comprise: the characteristic action states of the bed leaving/returning process detected during working are a plurality of typical action states of a person to be detected in the bed leaving/returning process, the characteristic action states can be detected through the combination of the node units, and the characteristic action states are extracted to help to judge the current physical state of the person to be detected, so that the detection efficiency and accuracy are effectively improved. Although the utility model can monitor different states of the personnel to be detected, whether the patients in different states are dangerous or not can not be judged, and whether the medical personnel are required to send an alarm to remind the corresponding sickbed to check the states of the patients or not can not be judged.
The different patient types have different bed leaving or lying requirements, and the bed leaving device or the bed leaving detection device provided by the prior art cannot judge whether the alarm needs to be sent and the alarm of what level is sent according to the different patient types and the corresponding bed leaving requirements, and the problem of sending false alarms exists in many cases. In the prior art, the action of non-bed-leaving is usually aimed at the patient who is not able to leave the bed at all, however, in an actual ward, the patient who is not able to leave the bed cannot rise due to the reasons such as paralysis, operation and the like, more patients who leave the bed are enough to support the patient to leave the bed, and the patient is selected to leave the bed because of lack of common knowledge, the action of violating doctor's advice is implemented, for example, the patient is addicted to smoke from the bed, and some patients are in the reason of self-shame cognition, and when the patient is not inserted with a urinary catheter but needs to urinate on the bed for a short period of time, the patient can choose to leave the bed to go to the toilet; these behaviour against orders pose a great threat to the health of the patient, for example, the patient with tuberculosis and hemoptysis must remain in absolute bed in the early stages, but some patients with tuberculosis and hemoptysis consider that the short movements do not have much influence on the body, the behaviour of getting down to the toilet will be performed, the medical staff cannot notice the state of the patient at any time, the family members also lack common sense of thinking and do not prevent the patient, the patient will experience squatting and standing movements during the toilet, hemoptysis is easily caused, and there is a risk of asphyxia.
Furthermore, there are differences in one aspect due to understanding to those skilled in the art; on the other hand, since the applicant has studied a lot of documents and patents while making the present invention, the text is not limited to details and contents of all but it is by no means the present invention does not have these prior art features, but the present invention has all the prior art features, and the applicant remains in the background art to which the right of the related prior art is added.

Example 4
When a patient with tuberculosis combined with hemoptysis is allowed to go out of bed for a long time after treatment but is not discharged, the patient or family members need to continue to observe for a period of time, but some patients or family members lack common knowledge, the patient is considered to have recovered, the patient is taken out of the hospital for home, the patient with tuberculosis combined with hemoptysis stops hemoptysis after treatment, but is influenced by various factors, the patient has the possibility of relapse, once the patient has the hemoptysis out of the hospital and is not timely in treatment, the patient has life danger, and the system generates the following judgment program for the condition: the patient's out-of-bed time is greater than the third time threshold and the patient's out-of-bed distance is greater than the third out-of-bed threshold.

Example 5
The second detection unit of the bed leaving detection alarm system provided in this embodiment includes a distance detection component 2 and a physiological index detection component 3. Preferably, the distance detection assembly 2 can be an infrared detector. Preferably, the physiological index detection component can be a wearable device. The wearable device can collect physiological parameter information of a patient and analyze whether the physiological parameter information of the patient is within a preset range. Based on the patient medical record information and department information of the patient acquired by the information input unit 41, the processor 4 automatically generates a physiological status monitoring direction of the patient, for example, if the patient is a heart failure patient in the department of cardiology, the detection direction is a heart rate; the patient is a respiratory white lung patient and the detection is directed to blood oxygen saturation. Based on the complexity of the patient behavior, the direction of the monitoring of the physiological state is determined according to the department and the illness state of the patient, if the physiological state is detected too much, the processor 4 needs to judge more contents, the prediction and result analysis of the patient behavior cannot be generated in time, and the problems of more judging errors, long judging time and the like can occur when the multi-factor judgment is performed.
The wearable device is communicatively connected to the processor 4. The wearable device transmits the judged physiological index result to the processor 4. The analysis unit 45 of the processor 4 combines the patient's physiological index judgment result and the distance information to generate an alarm instruction. According to a preferred embodiment, the wearable device can be a smart watch. The intelligent watch worn by the patient can monitor the physiological state of the patient in real time and generate physiological parameter information, and the physiological index information at least comprises heart rate, blood oxygen saturation and blood pressure information. Preferably, the physiological index comprises a first physiological parameter, a second physiological parameter and a third physiological parameter. The first physiological parameter, the second physiological parameter and the third physiological parameter are physiological parameters determined by doctors according to the illness state of patients and departments where the doctors are located. Preferably, for a patient undergoing cardiac surgery, the first physiological parameter is set to heart rate, the second physiological parameter is set to arterial pressure, and the third physiological parameter is set to central venous pressure. Meanwhile, the intelligent watch can judge whether the detected physiological information is in a preset parameter range. After the patient leaves the bed, when the physiological parameter information of the patient is in the preset parameter range, the physical state of the patient is good, and the analysis unit judges that the alarm is not sent out. After the patient leaves the bed, if the physiological parameter information is not within the preset parameter range, the analysis unit 45 combines the physiological parameter information and the distance information to determine whether the current physical condition of the patient can return to the bed by itself, so as to generate the following determination program: the analysis unit 45 combines the physiological parameter information and the distance information of the patient to judge that the patient can return to the sickbed by himself, prompts the patient to return to the sickbed immediately, monitors whether the patient returns to the sickbed smoothly, and observes whether the physiological parameter of the patient returns to normal after the patient returns to the sickbed. The analysis unit combines the physiological parameter information and the distance information of the patient to judge that the patient can not return to the sickbed by oneself, and sends out an alarm instruction to prompt medical staff to reach the position of the patient, thereby helping the patient to return to the sickbed and taking corresponding treatment measures for the patient. The physiological parameters of the present embodiment are exemplified by heart rate and blood oxygen saturation, but not limited thereto, the preset range of heart rate in the smart watch is 60-100 times/mmin, and the preset range of blood oxygen saturation is 95-100%, and the present embodiment is exemplified by female patients aged 25 years. In this embodiment, the first distance threshold is set to 20m, the second distance threshold is set to 50m, the first time threshold is set to 5min, and the second time threshold is set to 10min.
Aiming at the condition that a patient with tuberculosis and hemoptysis is allowed to get out of bed to walk after treatment, the out-of-bed detection alarm system generates the following judging program:
when the smart watch monitors that the heart rate of the patient is 90 times/min and the blood oxygen saturation is 95%, the heart rate and the blood oxygen saturation are both in the preset range, the patient distance from the bed is smaller than the second distance threshold, the patient distance from the bed is smaller than the first time threshold, the patient advancing direction is the ward, the analysis unit 45 judges that the physical condition of the patient is stable, the patient returns to the sickbed in the middle of returning to the sickbed, the patient can return to the sickbed in the prescribed time of medical advice, and the judgment result of the analysis unit 45 is that no alarm is sent out.
When the smart watch monitors that the heart rate of the patient is 90 times/mmin, the blood oxygen saturation is 95%, the patient's distance from the bed is greater than a second distance threshold, the patient's distance from the bed is greater than a second time threshold, the patient's travelling direction is far away from the ward, the analysis unit judges that the patient's physical condition is stable, the patient can return to the ward by oneself, but the travelling direction of the patient is not in the direction of returning to the ward, the patient can not return to the ward in the prescribed time of doctor's advice, the judgment result of the analysis unit 45 is that the third-level alarm needs to be sent, the analysis unit 45 sends the instruction of the third-level alarm to the alarm unit, and the alarm unit prompts that the patient has exceeded the prescribed distance from the bed, and needs to return to the ward.
When the smart watch monitors that the heart rate and the blood oxygen saturation parameters of the patient far exceed or are lower than the preset range, for example, the patient has hemoptysis in the process of leaving the bed, the heart rate is increased to 130 times/min, the blood oxygen saturation is lower than 95%, for example, 85%, the distance of the heart rate and the blood oxygen saturation exceeds a second distance threshold, at the moment, the patient is in a dangerous state, the analysis unit judges that the current physical condition of the patient is judged by combining the physiological parameter judgment information and the distance information, the patient cannot continue to walk, the patient cannot return to the sickbed by himself, the condition of the patient is dangerous, and the analysis unit 45 sends a first-level alarm instruction to the alarm unit; medical staff needs to reach the position of the patient immediately after receiving the first-level alarm information of the alarm unit, so that the patient is helped to return to the sickbed and take emergency measures for the patient.
When the smart watch monitors that the heart rate, the blood oxygen saturation and the blood pressure of the patient are slightly higher or lower than the preset range, for example, the heart rate of the patient is increased to 110 times/min due to fatigue caused by the patient in the process of walking away from the bed, the blood oxygen saturation is about 95%, the distance is smaller than the second distance threshold, the analysis unit 45 judges that the patient needs to return to the sickbed immediately according to the physiological parameter judgment information and the distance information, so that the patient can return to the sickbed by himself and does not need other people, the judgment result of the analysis unit 45 is that three-level alarm needs to be sent, the analysis unit 45 sends an instruction of the three-level alarm to the alarm unit 6, and the alarm unit 6 generates three-level alarm to prompt the patient to return to the sickbed. After the patient returns to the sickbed for a period of time, if the physiological parameters of the patient return to normal, the analysis unit 45 receives that the physiological parameters of the patient are within a preset range, and the judgment result is that no alarm is sent. When the patient returns to the sickbed for a period of time and the physiological parameters of the patient do not return to normal, the physiological parameters still exceed or fall below the preset range, the analysis unit 45 receives the judgment information of the physiological parameters, analyzes that the second-level alarm instruction needs to be sent, and sends out the voice prompt of the second-level alarm after the alarm unit 6 receives the instruction, so that the medical staff is prompted to check and rescue the patient in time.
