[0022] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.
[0023] In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.
[0024] The present application provides a getting-up alarm device, which uses an ultrasonic sensor at the head of the bed to detect whether the chest rises and falls to determine whether the patient is bedridden, and uses a sitting-up sensor to detect whether the patient is sitting up. The two are combined to determine the patient's status in bed, and provide accurate alarm information to nursing staff (including medical staff and nursing workers, etc.) through the nursing-side communication equipment, thereby improving the quality of nursing and helping to reduce the mental stress of nursing staff. The present application also provides a getting-out-of-bed sensor for detecting whether the patient has gotten out of bed, and gives different alarm information for the patient sitting up and getting out of bed, accurately conveying the patient's status and further improving the quality of nursing. In addition, in the present application, a camera is also provided at the head of the bed, which facilitates nursing staff to intuitively understand the patient's actions through the display screen of the nursing-side communication equipment. Voice guidance is also provided to patients through a microphone at the head of the bed, which can delay or prevent patients from falling, further improving the quality of nursing.
[0025] It should be noted that the bed alarm device provided in the present application is not only used for monitoring patients at night, but can also be used for monitoring patients during the day.
[0026] like Figure 1 As shown, the bed-waking alarm device provided in the present application includes a sitting-up sensor 140 and an ultrasonic sensor 150 arranged on the bed 100 and a remote nursing-end communication device 200 .
[0027] The ultrasonic sensor 150 is arranged on the bedside 120, and the detection height of the ultrasonic sensor 150 covers the range of chest rise and fall of the patient when the patient is lying in bed. The ultrasonic sensor 150 detects the patient's lying state and whether the patient has vital signs. If the ultrasonic sensor 150 can detect the rise and fall of the chest, it means that the patient has vital signs and is in a lying state.
[0028] The sit-up sensor 140 is disposed on the bedside 120. The detection height of the sit-up sensor 140 is higher than the maximum height of the patient's body when lying in bed. The sit-up sensor detects the process of the patient changing from a lying position to a sitting position. If the sit-up sensor 140 detects a body part of the patient, it indicates that the patient is in a sitting position, otherwise, the patient is in a lying position.
[0029] The nursing end communication device 200 is connected to the sitting-up sensor 140 and the ultrasonic sensor 150 through wireless frequency modulation signals, and the nursing end communication device 200 is provided with an alarm.
[0030] Specifically, if the ultrasonic sensor 150 can detect the rise and fall of the chest, no signal is sent to the nursing communication device 200. If the ultrasonic sensor 150 cannot detect the rise and fall of the chest, a first detection signal is sent to the nursing communication device 200. If the sit-up sensor 140 detects the patient's body part, a second detection signal is sent to the nursing communication device 200; if the sit-up sensor 140 cannot detect the patient's body part, no signal is sent to the nursing communication device 200. If the nursing communication device 200 receives the first detection signal and the second detection signal within a preset time interval, it means that the patient has sat up, and the nursing communication device 200 issues an alarm.
[0031] As an embodiment, the sitting and rising sensor 140 is a photoelectric sensor or an infrared sensor.
[0032] Preferably, the bed alarm device further includes a bed-getting-out sensor 170, which is arranged on the bottom surface of the side of the bed board 110 for getting out of bed (e.g., the two longer side sides of the bed board or the side not against the wall), and the bed-getting-out sensor 170 is connected to the nursing end communication device 200 via wireless FM signal communication. The bed-getting-out sensor 170 detects the patient's foot stepping out of the bed, and when the bed-getting-out sensor 170 detects the patient's body part, indicating that the patient is ready to get out of the bed, the bed-getting-out sensor 170 sends a third detection signal to the nursing end communication device 200, otherwise, the bed-getting-out sensor 170 does not send a signal to the nursing end communication device 200.
[0033] In this preferred embodiment, when the patient is in a state of sitting up but not getting out of bed (the nursing end communication device 200 only receives the first detection signal and the second detection signal, but does not receive the third detection signal), the alarm sends a first-level alarm message to remind the nursing staff that the patient may intend to get out of bed, and to check on the patient at the bedside in advance to prevent the occurrence of a fall; when the patient is in a state of getting out of bed (the nursing end communication device 200 receives the third detection signal), the alarm sends a second-level alarm message to remind the nursing staff that the patient is ready to get out of bed, and to check on the patient at the bedside as soon as possible to prevent the occurrence of a fall. If the nursing end communication device 200 only receives the first detection signal, but does not receive the second detection signal and the third detection signal, the alarm sends a third-level alarm message to remind the nursing staff that the patient currently has no vital signs.
[0034] As an embodiment, the bed getting out sensor 170 is a photoelectric sensor or an infrared sensor.
[0035] Preferably, the bed alarm device also includes a camera 130, which is fixed on the upper part of the bedside 120. The shooting range of the camera 130 covers the entire bed board and the area within a preset distance from the bed board. The camera 130 is connected to the nursing-end communication device 200 through 4G / 5G and other network communications, and transmits real-time images to the nursing-end communication device 200, so that the nursing staff can intuitively see the patient's actions through the display screen of the nursing-end communication device 200 to accurately judge the patient's condition.
[0036] Preferably, the bed alarm device further comprises a microphone 160, which is fixed on the bedside, and the microphone 160 is connected to the nursing end communication device 200 via wireless FM signal communication. The nursing end communication device 200 is also provided with a voice input and output device, and the nursing staff can provide voice guidance to the patient through the nursing end communication device 200 and the microphone 160 to delay or prevent the patient from falling.
[0037] Preferably, the nursing communication device 200 is a handheld device, which is convenient for nursing staff to understand the patient's status at any time while performing other activities. More preferably, it is a mobile phone or tablet. While completing the nursing function, the nursing staff can also send relevant information to other departments in the hospital or the patient's relatives through the mobile phone or tablet.
[0038] This application can alert nursing staff during the patient's getting up process that the patient is likely to get up and leave the bed, which can not only prevent the risk of patients falling, but also reduce the mental stress of nursing staff caused by adverse events of falls occurring to patients at high risk of falling, thereby improving the quality of nursing care.
[0039] Although some specific embodiments of the present application have been described in detail by way of example, it should be understood by those skilled in the art that the above examples are only for illustration, not for limiting the scope of the present application. It should be understood by those skilled in the art that the above embodiments may be modified without departing from the scope and spirit of the present application. The scope of the present application is defined by the appended claims.
