Technical Field

The invention relates to the technical field of medical treatment, in particular to an intelligent device for preventing a high-risk falling patient from leaving a bed without permission.

Background

A fall refers to a sudden, involuntary, unintended change in position, lying on the ground or lower level. According to the survey results of the Chinese causes of death in 2015, the first cause of death of the elderly over 65 years old in the category of injury diseases is shown in the classification of falling sites, particularly in hospitals, the falling of inpatients is the most frequent adverse event in hospitals, the incidence rate of falling of inpatients accounts for more than 38% of the adverse event in hospitals, the falling of inpatients not only can cause negative effects on the health and psychological states of the inpatients, but also can even prolong the hospitalization time in severe cases, and increase the hospital cost.

At present, various hospitalized patients with serious or high falling risk can be continuously found in the process of hospital diagnosis and treatment, the part of the patients has certain mobility, the bed leaving rate during hospitalization is high, the falling situation is frequent, because medical staff are difficult to keep at the side of the patient bed all the time, a pager control switch corresponding to the patient bed is usually arranged on the wall close to the patient bed in the ward, so that the patients can call the medical staff to assist the bed leaving activity when leaving the bed, however, in the process of actual use, the patients rarely use the pager to call the medical staff to assist the bed leaving activity, the patients can leave the bed by themselves in most cases, when the patients leave the bed by themselves without accompanying people, the patients are easy to fall and hurt due to poor walking stability, the medical expenses are increased, and even the lives are seriously threatened, causing death. The existing hospital bed of the hospital is only used for the lying and rest of the patient, does not have the function of reminding the patient to leave the bed, cannot limit the patient to move away from the bed by oneself, and is difficult to meet the actual application requirements.

How to solve the above problems is a technical problem to be solved urgently.
