The thin film contact sensor (13) is used to monitor whether the test subject is located away from the monitoring component (10). When the tested subject is placed on the monitoring component (10), the monitoring component (10) refers to the physiological characteristics information of the test subject to generate a corresponding monitoring signal. The main controller (20) then acquires a monitoring result by referring to the monitoring signal. When the test subject leaves the monitoring component (10), the main controller (20) receives bed departure information. The technical solution provided by the embodiment does not require a user to wear a device. The user needs only to be placed on the monitoring component (10) to monitor physiological characteristics of the user and whether the user has left the monitoring component (10).

The monitoring unit 10 integrates the piezoelectric film sensor 12 and the film contact sensor 13, and the monitoring member 10 is usually placed on the bed below the chest of the human body (subject), and can also be placed on a sofa or a cushion for use. The piezoelectric film sensor 11 is used to monitor physiological characteristic information of the human body, including a respiratory signal, a heartbeat signal, and body motion information. The membrane contact sensor 13 is used to monitor whether the human body leaves the monitoring component 10. Meanwhile, in an embodiment of the present invention, a plurality of monitoring areas are disposed on the monitoring component 10, and the user does not need to fixedly contact a certain position or a certain area of the monitoring component 10, as long as the user's chest is placed on the monitoring component. It can be monitored on 10th.
而且，监测部件10不用穿戴在使用者的身上，也不用在使用者身上多个传感器电极和复杂的连线，有效避免了病人身上粘贴多个电极的接触式测量，当被测体(使用者)置于监测部件10上时，多个监测区域中的部分监测区域根据被监测体的生理特征信息产生相应的监测信号，生理特征包括但不限于心跳信息、呼吸信息和体动信息等，体动信息包括但不限于翻身、移动等。主控装置20根据监测信号得到监测结果，监测结果包括但不限于呼吸次数，呼吸频率、心跳次数，心跳频率、体动次数和离床次数，等等。Moreover, the monitoring component 10 does not need to be worn on the user's body, nor does it require multiple sensor electrodes and complicated wiring on the user, thereby effectively avoiding contact measurement of sticking multiple electrodes on the patient, when the subject (user) When placed on the monitoring component 10, a part of the monitoring areas of the plurality of monitoring areas generate corresponding monitoring signals according to the physiological characteristic information of the monitored body, and the physiological features include, but are not limited to, heartbeat information, respiratory information, body motion information, etc. Mobile information includes, but is not limited to, turning over, moving, and the like.

下面对本实用新型实施例进行详细的介绍。The embodiments of the present invention are described in detail below.
为增加监测部件10的使用寿命，同时也为了增加监测部件10的美观性，本实用新型实施例中可选地，还包括：外罩11；外罩11具有中空内腔；监测部件10置于中空内腔中；监测部件10的一侧边缘设有用于连接主控装置20的连接端子；连接端子从外罩11的一侧边伸出中空内腔。In order to increase the service life of the monitoring component 10, and also to increase the aesthetics of the monitoring component 10, the embodiment of the present invention optionally further includes: a cover 11; the outer cover 11 has a hollow inner cavity; and the monitoring component 10 is placed in the hollow In the cavity, one side edge of the monitoring component 10 is provided with a connection terminal for connecting the main control device 20; the connection terminal protrudes from a side of the outer cover 11 to the hollow inner cavity.
继续参见图2，如图2所示：监测部件10设置于外罩11的中空内腔中，防止监测部件10与外界的接触，减缓了监测部件10的磨损，增加了监测部件10的使用寿命。同时，外罩11的制作材料可以是常用的布料，使得监测部件10的外观更加美观。使用者在家庭中使用时，也不会因为监测部件10的外观显得很突兀，使用者也可以在外罩11的外表面增加其他外罩等覆盖物，不会影响监测部件10的使用。而且，监测部件10置于中空内腔中，可以从外罩11的一侧将用于连接主控装置20的连接端子伸出中空内腔，外罩11的设置不影响监测部件10与主控装置20的连接。Continuing to refer to FIG. 2, as shown in FIG. 2, the monitoring component 10 is disposed in the hollow interior of the housing 11 to prevent contact of the monitoring component 10 with the outside, slowing the wear of the monitoring component 10, and increasing the service life of the monitoring component 10. At the same time, the material of the outer cover 11 can be a commonly used cloth, so that the appearance of the monitoring member 10 is more beautiful. When the user uses the home, the appearance of the monitoring component 10 does not appear to be abrupt, and the user can add a cover such as another cover to the outer surface of the outer cover 11 without affecting the use of the monitoring component 10. Moreover, the monitoring component 10 is placed in the hollow inner cavity, and the connection terminal for connecting the main control device 20 can be extended from the side of the outer cover 11 to the hollow inner cavity, and the arrangement of the outer cover 11 does not affect the monitoring component 10 and the main control device 20. Connection.
在监测部件10的外部设置外罩11，可以有效减缓监测部件10的磨损，但是，监测部件10与外罩11之间有可能存在缝隙，使用者在使用过程中由于翻 身、起床等动作，导致外罩11与监测部件10之间产生相对移动，这样就相对增加了监测部件10的磨损，因此本实用新型实施例中可选地，监测部件10与中空内腔的内壁贴合。例如，使用胶水等能起到粘合作用的物质将监测部件10与中空内腔的内壁贴合。The outer cover 11 is disposed outside the monitoring component 10, which can effectively slow the wear of the monitoring component 10. However, there may be a gap between the monitoring component 10 and the outer cover 11, and the user turns over during use. The movement of the body, the waking, and the like causes a relative movement between the outer cover 11 and the monitoring component 10, which relatively increases the wear of the monitoring component 10. Therefore, in the embodiment of the present invention, the monitoring component 10 and the inner wall of the hollow inner cavity are optionally fit. For example, the monitoring member 10 is attached to the inner wall of the hollow inner cavity using a substance capable of bonding such as glue.
监测部件10设置在中空内腔时，监测部件10与中空内腔的内壁贴合连接，这样就防止在使用过程中，由于使用者的动作导致监测部件10与外罩11之间发生相对移动的问题。When the monitoring component 10 is disposed in the hollow inner cavity, the monitoring component 10 is attached to the inner wall of the hollow inner cavity, thereby preventing the relative movement between the monitoring component 10 and the outer cover 11 due to the user's motion during use. .
下面对监测部件10包括压电薄膜传感器12和薄膜触点传感器13的情况进行详细介绍。The case where the monitoring member 10 includes the piezoelectric film sensor 12 and the film contact sensor 13 will be described in detail below.

Specifically, when the user lies on the piezoelectric film sensor 12, the charge distribution of the electrode surface of the electrode having the upper and lower positional relationship changes, and the internal electrode is generated while generating opposite signs on the two surfaces thereof. The charge, and the deformation of the force is proportional to the charge signal. When the deformation changes, the charge signal changes, and when the deformation disappears, it returns to the uncharged state, thereby converting the dynamic mechanical energy into electricity.
