Physiological information monitoring device with self-detection function

This creation is about a physiological information monitoring device, in particular a physiological information monitoring device with self-detection function.

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. The physiological information monitoring device of the prior art only judges whether an abnormality occurs according to the signal output by the sensing component. Therefore, when the physiological information monitoring device issues a warning signal, it usually represents an abnormal condition of the object to be tested. However, the poor line of the physiological information monitoring device or the failure of the sensing component may cause an error signal to cause the caregiver to be exhausted, or misplace the physiological information, causing the nursing staff to miss the ambulance opportunity.

In summary, how to provide a physiological information monitoring device that can identify an abnormal condition as an abnormality of the object to be tested or a device failure is an urgently needed goal.

The present invention provides a physiological information monitoring device with self-detection function, which uses an analog signal generator to generate an analog signal, and allows the analog signal to pass through the entire device loop, and judges whether the analog signal is correctly received at the end of the loop. Whether the device itself is faulty.

The physiological information monitoring device with self-detection function according to an embodiment of the present invention comprises a physiological information sensing component, a signal amplifier, a filter, a determining module and an analog signal generator. The physiological information sensing component is configured to sense physiological information of one of the tested objects and output a physiological information signal. The signal amplifier is electrically connected to the physiological information sensing component for amplifying the physiological information signal. The filter is electrically connected to the signal amplifier to filter out one of the amplified physiological information signals. The judging module is electrically connected to the filter, and is configured to determine whether the object under test is an abnormal state according to the filtered physiological information signal. The analog signal generator is electrically connected to the physiological information sensing component for generating an analog signal and outputting to the physiological information sensing component, wherein the analog signal is transmitted to the determining module in the same path as the physiological information signal for use in the determining module. The group judges whether the physiological information monitoring device is abnormal according to the analog signal.

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 , a physiological information monitoring device with self-detection function according to an embodiment of the present invention includes a physiological information sensing component 11 , a signal amplifier 12 , a filter 13 , a determination module 14 , and an analog signal generation device . Device 15. The physiological information sensing component 11 is configured to sense physiological information of one of the tested objects, and convert the physiological information into an electrical physiological information signal PS for output. For example, the subject may be a baby, an elderly person or a patient; physiological information may be respiratory frequency, heart rate/pulse frequency, turning motion, and the like. In one embodiment, the physiological information sensing component 11 can be a motion sensor, for example, a pressure sensor or an acceleration sensor.

The signal amplifier 12 is electrically connected to the physiological information sensing element 11. The signal amplifier 12 receives the physiological information signal PS outputted by the physiological information sensing element 11 and amplifies it and outputs it. The filter 13 is electrically connected to the signal amplifier 12. The filter 13 receives the amplified physiological information signal PS outputted by the signal amplifier 12, and filters one of the noises to output. The judging module 14 is electrically connected to the filter 13. The judging module 14 can determine whether the object to be tested is in an abnormal state according to the filtered physiological information signal PS, such as breathing suspension, heartbeat/pulse stop, or no turning over for a long time. It can be understood that the judgment manners are different for different physiological information.

The analog signal generator 15 is electrically connected to the physiological information sensing element 11. The analog signal generator 15 can generate an analog signal SS and output it to the physiological information sensing element 11. The analog signal SS is transmitted to the determination module 14 via the same path as the physiological information signal PS, that is, via the physiological information sensing element 11, the signal amplifier 12, and the filter 13. The judging module 14 can determine whether the physiological information monitoring device is abnormal according to whether the analog signal SS (for example, signal amplitude and time) is correctly received. In an embodiment, the analog signal SS can be an electrical signal or a physical physical quantity. For example, the analog signal generator 15 can be an electrical signal generating circuit or a vibration motor. It can be understood that the analog signal generator 15 can generate an appropriate physical physical quantity according to the sensing principle of the different physiological information sensing elements 11.

In one embodiment, the physiological information monitoring device of the present invention further includes a warning module 16 electrically connected to the determination module 14. The warning module 16 can generate a warning signal according to the determination result DR of one of the determination modules 14 to prompt the user that the object to be tested is abnormal or the physiological information monitoring device is abnormal. 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.

In an embodiment, the analog signal generator 15 can generate an analog signal SS when the physiological information monitoring device is activated to confirm that the physiological information monitoring device functions normally. Alternatively, the analog signal generator 15 may generate an analog signal SS when the physiological information monitoring device starts monitoring the subject, for example, when the baby is placed on the physiological information monitoring device. In addition, the analog signal generator 15 can also be arbitrarily triggered by the user to generate the analog signal SS. In short, when the user thinks it is necessary, the analog signal generator 15 can be triggered to generate the analog signal SS by inputting the trigger signal TS through a user interface, such as a button. In an embodiment, the analog signal generator 15 can periodically generate the analog signal SS, and transmit the self-test result to the host or store it for the user to confirm the normal function of the physiological information monitoring device. Referring to FIG. 2, in an embodiment, the analog signal generator 15 is further electrically connected to the determining module 14. According to the architecture, the determining module 14 can determine that the object to be tested is abnormal according to the physiological information signal PS. The output of a trigger signal TS triggers the analog signal generator 15 to generate an analog signal SS to confirm that the subject is abnormal or is only a physiological information monitoring device.

The following is a brief description of the operation of the physiological information monitoring device with self-detection function of the present invention. In the case where the object to be tested is not actually monitored, for example, when the physiological information monitoring device is activated or the user triggers the self-detection function, the analog signal generator 15 generates the analog signal SS and transmits it to the judgment mode in the same path as the physiological information signal PS. Group 14. If the judging module 14 can correctly receive the analog signal SS, it determines that the physiological information monitoring device is functioning normally, and if not, it determines that the physiological information monitoring device is faulty.

In the case of actually monitoring the object to be tested, when the judging module 14 receives the abnormal physiological information signal PS, for example, if there is no signal or the signal is weak, the judging module 14 triggers the analog signal generator 15 to generate the analog signal SS, and The path of the physiological information signal PS is transmitted to the determination module 14. If the judging module 14 can correctly receive the analog signal SS, it is determined that the physiological information monitoring device is functioning normally, and the warning signal of the abnormality of the object to be tested is issued, and if not, the physiological information monitoring device is determined to be faulty, and the physiological information monitoring device is faulty. Warning signal. It can be understood that when both the physiological information signal PS and the analog signal SS are abnormal, it cannot be excluded that the physiological information signal PS is actually abnormal. Therefore, preferably, when the warning signal of the physiological information monitoring device is issued, the user should also be prompted to pay attention to whether the object to be tested is abnormal.

In summary, the physiological information monitoring device with self-detection function of the present invention uses an analog signal generator to generate an analog signal and allows the analog signal to pass through the entire device loop. Therefore, it is confirmed by the judgment module at the end of the loop whether it can be correctly received. The analog signal can be used to identify that the abnormality is caused by the abnormality of the measured object or only the failure of the device itself.
