Physiological information monitoring device

This creation relates to a monitoring device, in particular a physiological information monitoring device.

The physiological information monitoring device can obtain physiological information of the subject (such as an infant, an elderly person, or a patient) to determine whether the subject is abnormal, such as a pause in breathing. Therefore, physiological information monitoring devices are an indispensable part of long-term care. A conventional physiological information monitoring device utilizes a piezoelectric sensing element to measure the activity of a subject, such as a breathing action. However, when the pressure sensing component does not change, the output signal does not differ. In other words, the monitoring device cannot recognize whether the object under test or the object has stopped moving. In addition, wireless transmission of monitoring data to the control terminal is a trend of the industry. Therefore, how to effectively reduce the power consumption of the monitoring device is also an important issue.

In summary, it is currently an urgent need to provide a physiological information monitoring device that can identify whether there is an abnormality of the object to be tested or the object to be measured and the power saving.

The present invention provides a physiological information monitoring device, which is provided with a push switch, which can recognize whether there is an abnormality of the object to be tested or the object to be tested by pressing the output of the switch, and can enter the power saving mode when there is no object to be tested. Reduce power consumption.

The physiological information monitoring device according to an embodiment of the present invention comprises a fixing member, a movable plate, a piezoelectric sensing component, a pressing switch and an elastic member. The movable board is used to carry a test object. The piezoelectric sensing component is disposed between the movable plate and the fixed component to monitor physiological information of one of the objects to be tested and output a corresponding physiological information signal. The pressing switch is disposed on one side of the piezoelectric sensing component, wherein the movable plate is movable relative to the fixing member in a pressing direction of one of the pressing switches to a pressing position and a releasing position, and when the movable plate is in the pressing position, pressing the switch and pressing The inductance measuring components are abutted together to make the pressing switch a pressing state, and the piezoelectric sensing component is activated to output a physiological information signal. The elastic element is disposed between the movable plate and the fixing member to drive the movable plate to return to a releasing position when the force is not applied, so that the pressing switch is in a released state.

In the following, the specific embodiments and the accompanying drawings are explained in detail, and it is easier to understand the purpose, technical content, characteristics and effects achieved by the present invention.

Referring to FIG. 1 and FIG. 2, the physiological information monitoring device 10 of one embodiment of the present invention comprises a fixing member 11, a movable plate 12, a piezoelectric sensing component 13, a pressing switch 14, and an elastic member 15. The movable plate 12 is disposed opposite to the fixing member 11 and movable relative to the fixing member 11. The movable panel 12 is used to carry a subject, such as an infant. In an embodiment, the fixing member 11 can be a lower cover, and the movable panel 12 can be an upper cover, and the upper cover and the lower cover can define an accommodating space 111, as shown in FIG. It should be noted that in an embodiment, the lower cover is an omitting component, and the support surface 30 (eg, table top, bed surface or floor, etc.) can be regarded as a fixing member.

The piezoelectric sensing element 13 is disposed between the movable plate 12 and the fixed member 11 , that is, in the accommodating space 111 . The piezoelectric sensing component 13 senses a pressure change caused by physiological information of the subject, such as a breathing motion, and converts it into a corresponding electrical physiological information signal PS for output. The push switch 14 is disposed on one side of the piezoelectric sensing element 13. The movable panel 12 is movable in a pressing direction D of one of the push switches 14 to a pressing position and a releasing position, so that the pressing switch 14 is in a pressed state or a released state. When the push switch 14 is in the pressed state, the piezoelectric sensing element 13 can sense the pressure change and output the corresponding physiological information signal PS. When the push switch 14 is in the released state, the piezoelectric sensing element 13 can be deactivated to reduce power consumption. It can be understood that the configuration of the piezoelectric sensing element 13 and the push switch 14 is not limited to the embodiment shown in FIG. For example, the positional exchange of the piezoelectric sensing element 13 and the push switch 14 can achieve the same or similar effects. The elastic member 15 is disposed between the movable panel 12 and the fixing member 11 for driving the movable panel 12 to return to the release position when the force is not applied, even if the push switch 14 is in the released state. For example, the resilient element 15 can be a spring.

In one embodiment, the physiological information monitoring device 10 of the present invention may include a limiting member 16 disposed on an opposite surface of at least one of the fixing member 11 and the movable panel 12. The stop element 16 limits the minimum distance of the movable panel 12 and the fixture 11. For example, the limiting element 16 can be a stud disposed on the inner side surface of the fixing member 11 (ie, the lower cover). The movable plate 12 (i.e., the upper cover) is moved toward the fixing member 11 under pressure, and stops when the movable plate 12 abuts against the stud of the retaining member 16, thus limiting the distance between the movable plate 12 and the fixed member 11. According to this configuration, it is possible to prevent the pressure sensing element 13 or the push switch 14 from being damaged by improper operation or excessive pressure.

Referring to FIG. 2 , in one embodiment, the physiological information monitoring device 10 of the present invention further includes a control and determination unit 17 electrically connected to the piezoelectric sensing component 13 and the push switch 14 . The control and determination unit 17 can receive the physiological information signal PS outputted by the piezoelectric sensing component 13 and determine whether the object to be tested is abnormal according to the physiological information signal PS. In addition, the control and determination unit 17 can switch the physiological information monitoring device 10 to a power saving mode when the push switch 14 is in the released state, for example, turning off the sensing function of the piezoelectric sensing component 13 and other unnecessary power consumption. Until the push switch 14 is in the pressed state, the control and determination unit 17 restarts the sensing function of the piezoelectric sensing element 13 and outputs the physiological information signal PS.

For example, when the baby is placed on the movable panel 12, the movable panel 12 is moved to the pressing position in the direction of the pressing member D in the pressing direction D, so that the pressing switch 14 and the piezoelectric sensing element 13 are pressed against each other. The switch 14 is pressed. At this time, the push switch 14 is in a pressed state, and the pressure change caused by the baby's breathing action can be transmitted to the piezoelectric sensing element 13 via the push switch 14 to measure the pressure change. In an embodiment, the movable panel 12 can be a hard material. According to this configuration, even if the placement position of the baby is deviated from the push switch 14 and the piezoelectric sensing element 13, the rigid movable panel 12 can effectively transmit the pressure change caused by the breathing to the piezoelectric sensing element 13. When the baby is lifted from the movable panel 12, the movable panel 12 is moved in the pressing direction D toward the releasing position in the pressing direction D due to the restoring force of the elastic member 15. At this time, the push switch 14 is in the released state, and the control and determination unit 17 can switch the physiological information monitoring device 10 to a power saving mode. It can be understood that when the pressure sensing component 13 does not sense the pressure change and the push switch 14 is in the pressed state, the control and determination unit 17 can determine that the baby is abnormal (for example, the breath is aborted) and issue a warning to remind Caregivers are treated appropriately.

Referring to FIG. 2 again, in an embodiment, the physiological information monitoring device 10 of the present invention further includes a signal processing unit 18 disposed between the piezoelectric sensing component 13 and the control and determining unit 17. The signal processing unit 18 is configured to process the physiological information signal PS output by the piezoelectric sensing component 13. For example, the signal processing unit 18 can amplify and filter out the physiological information signal PS and output the noise to the control and determination unit 17 for determination. In one embodiment, the physiological information monitoring device 10 of the present invention further includes an alerting unit 19 electrically connected to the control and determining unit 17. The warning unit 19 can generate a warning signal according to the determination result DR of one of the control and determination units 17 to prompt whether the user object is in an abnormal state. For example, the warning signal can be used to notify the user of an abnormal condition for a sound (such as a voice or a buzzer), a light (such as a pop-up window message or a light number), a vibration, or a combination thereof. Other means of notifying users of the warnings are not within the scope of this creation, such as sending emails, mobile newsletters or instant messaging.

Referring to FIG. 1 again, in an embodiment, the physiological information monitoring device 10 of the present invention further includes a cushion 20 disposed between the fixing member 11 and a supporting surface 30. The cushion 20 isolates the vibration from the support surface 30 to prevent external shocks from being transmitted to the piezoelectric sensing element 13 and affecting the accuracy of the sensing. Referring to FIG. 3 to FIG. 6 together, in an embodiment, the cushion 20 includes a plurality of elastic groups 21. For example, the elastic groups 21 may be arranged in an array. Each of the elastic groups 21 further includes a first elastic protrusion 211 , a second elastic protrusion 212 , and a third elastic protrusion 213 . The protruding heights H1, H2, and H3 of the first elastic protruding portion 211, the second elastic protruding portion 212, and the third elastic protruding portion 213 are also different.

According to this configuration, the cushion 20 can absorb a large range of pressure. For example, in the normal case, when the subject to be measured and the physiological information monitoring device 10 are placed, only the highest first elastic protrusion 211 is compressed and deformed. Therefore, the pressure change caused by the external vibration can still be absorbed by the second elastic protrusion 212 and the third elastic protrusion 213 which have not been deformed. It will be appreciated that those of ordinary skill in the art to which the present invention pertains may modify the composition and configuration of the flexible group 21 to suit different needs. For example, each elastic group 21 includes only the first elastic protrusions 211 and the second elastic protrusions 212 of different protruding heights.

In summary, the physiological information monitoring device of the present invention can determine whether there is an object to be measured by pressing the switch to the pressing state or the releasing state, so that it is possible to recognize whether there is an abnormality of the object to be tested or the object to be measured. In addition, when the push switch is in the pressed state, the monitoring device can be further switched to a power saving mode to reduce the consumption of power.

The embodiments described above are only for explaining the technical idea and characteristics of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement them according to the scope of the patent. That is, the equivalent changes or modifications made by the people in accordance with the spirit revealed by this creation should still be covered by the scope of the patent of this creation.
