Description
Technical Field
The utility model relates to the technical field of patient care equipment, in particular to a protection system for early warning of falling of a patient into a bed.
Background
A falling event occurs at a medical facility, and for elderly patients, a single falling may have fatal consequences. Although there are various management actions to prevent the occurrence of a bed drop event, the patient's bed drop behavior may be only at one instant, and difficult to predict and more difficult to refrain. For this reason, some hospitals take special care to prevent adverse medical events. But this not only increases the labor cost but also consumes a lot of effort from the healthcare worker.
At present, a learner predicts whether a patient will fall into a bed or not by calculating the gravity center of the patient and combining an infrared alarm device, but in practice, a great error may be caused by calculation due to the change of the body position of the patient. In addition, a learner can judge whether the patient falls down by using an image recognition mode, but installing a camera in a ward can seriously violate the privacy of the patient, and even the patient can generate resisting emotion. There are also scholars who detect the patient's exit from the bed with wearable devices, but wearable devices can bring great inconvenience to the patient while sleeping at night. Although the above methods have some effects, each method has limitations and can not early warn the patient in time to fall down. Therefore, the method has important significance on timely detecting and early warning protection of the hidden danger of falling into the bed of the patient.
