[0001] The present application relates to the technical field of monitoring devices, and more particularly, to an alarm device for monitoring the postural changes of the lower limbs. Background Art

[0002] In the prior art, for patients or the elderly who need to be monitored due to physical problems, they mostly need to stay in bed for rest. However, many of them still have the need to get out of bed to use the toilet or engage in other activities. When there is a need to get out of bed, many of the wards have no clear awareness of their physical functions and get out of bed alone without the presence of the monitoring staff. At this time, it is extremely easy to fall. Most of the existing monitoring devices can only remind the monitor to provide first aid after the ward has fallen, but cannot monitor the action of the ward getting out of bed and timely remind the monitor to pay attention.

[0003] At the same time, due to the different physical functions of different wards, for the wards who are inconvenient to wear monitoring devices on the upper body, such as patients who have undergone surgery on the upper body, the elderly with weak upper bodies, etc., it is difficult to detect their tendency to get out of bed in time through the monitoring device, so the monitor cannot be notified to prevent them from falling when getting out of bed.

[0004] Therefore, it is necessary for the inventor to design a new alarm device for monitoring the postural changes of the lower limbs to overcome the above problems. Summary of the Invention

[0031] In addition, the meaning of the term "a plurality of" shall be two or more.

[0032] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0033] As Figures 1 to 5 shown, an alarm device for monitoring the postural changes of the lower limbs includes an induction end and an alarm end that are electrically connected to each other, and an installation structure; wherein: the induction end is fixedly installed on the lower limbs of the human body through the installation structure, and is used for monitoring the height change data of the lower limbs of the human body, processing the data and sending a signal to the alarm end; the alarm end is used for receiving the signal sent by the induction end and emitting an alarm.

[0034] Specifically, the induction end is fixed on the lower limbs of the human body through a fixing device. When the human body is in a lying state, the induction end is at a certain height position. When the human body wants to get out of bed, the lower limbs will gradually approach the ground, and thus the height position changes. This change is sensed by the induction end, and the induction end transmits this change signal to the alarm end. The alarm end emits an alarm signal to inform the guardian (such as the children of the elderly, hospital nurses, nursing home caregivers, etc.) that the person being monitored has a tendency to get out of bed, so as to rush to the side of the person being monitored to ask about their needs and assist them in getting out of bed, preventing them from falling, and effectively protecting the person being monitored from harm. In this embodiment, by fixing the induction end for monitoring the height position change on the lower limbs of the human body, when the human body has a tendency to get out of bed, its height will inevitably change, thereby judging that the person being monitored has a tendency to get out of bed, and timely notifying the person being monitored through the alarm end, thereby protecting the person being monitored and reducing the risk of falling. This device is fixed on the lower limbs and is very user-friendly for users with inconvenient upper limbs to wear devices.

[0035] The induction end includes a height sensor 1, a microprocessor 2, and a signal transmitting module 3. The height sensor 1 is used for monitoring the height data of the lower limbs of the human body and transmitting the data to the microprocessor 2. The microprocessor 2 is used for processing the height data and transmitting the processing result to the alarm end through the signal transmitting module 3. Specifically, the height sensor 1 is used for sensing the height change data of its fixed position when the human body gets out of bed, and transmitting the data to the microprocessor 2. The microprocessor 2 is used for judging whether the data exceeds the data threshold for judging the tendency to get out of bed. If it exceeds the threshold, it means that the person being monitored has a tendency to get out of bed, and then an alarm signal is sent to the alarm end through the signal transmitting module 3.

[0036] The alarm terminal includes a signal receiving module, a microcontroller, and an alarm device body. The signal receiving module is used to receive the signal from the signal transmitting module 3 and transmit it to the microcontroller. The microcontroller controls the alarm device body to emit an alarm according to the signal received by the signal receiving module. Specifically, after the signal receiving module receives the alarm signal sent by the signal transmitting module 3, it transmits the signal to the microcontroller, and the microcontroller controls the alarm device body to emit an alarm after identifying the signal.

[0037] The height sensor 1 is a barometric pressure sensor. Specifically, at different altitudes, the air pressure is also different. By sensing the change in air pressure, the change in height can be sensed. It should be noted that when using a barometric pressure sensor, it cannot be covered by clothes or quilts to avoid affecting the sensing accuracy. In addition to using a barometric pressure sensor, an electromagnetic sensor can also be used. Electromagnetic coils are laid on the ground, and at different heights from the ground, the electromagnetic force sensed by the electromagnetic sensor is different, thereby sensing the change in height. This sensor is more accurate than the barometric pressure sensor, but the usage cost is higher.

[0038] The signal transmitting module 3 and the signal receiving module include one or more of a WIFI module, a Bluetooth module, and a 4G module. The signal transmitting module 3 and the signal receiving module can be directly wirelessly connected or indirectly connected through a relay station. Any wireless connection method that can make the two connected can be applied here. In actual application, it should be considered that the response time after the two are connected should not be too long to avoid excessive delay of the alarm signal.

[0039] The alarm device body includes one or more of a sound and light alarm, a vibration motor, and a buzzer. Specifically, any alarm device body that can enable the guardian to perceive in time can be applied here.

[0040] The installation structure includes a housing 4 and a fixing component. The sensing end is fixedly arranged inside the housing 4, and the housing 4 is fixedly installed on the lower limb of the human body through the fixing component. The fixing component includes an annular elastic band 5 or a magic tape fixedly arranged on the housing 4. The annular elastic band 5 is wound around the ankle. Specifically, the sensing end is installed in the housing 4. When a barometric pressure sensor is used in the sensing end, it should also be noted that the housing 4 should have ventilation holes to avoid its inability to sense the change in height. When using the installation method of the elastic band, it only needs to be worn around the ankle in the way of putting on socks. When using the magic tape method, it only needs to be pasted on the clothes at the ankle. It should be noted that the sensing end and the housing 4 here should be miniaturized and lightened to reduce the discomfort of the ward when using. Regarding the installation position, in addition to the ankle, other positions on the lower limb are also possible. It's just that the height change is the largest when getting out of bed at the ankle, and the tactile organs at the ankle have relatively weak perception, causing less discomfort to the ward.

[0041] The above are only the preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the protection scope of the present application.
