DETAILED DESCRIPTION

[0028] In order to make the structure and characteristics as well as the effectiveness of the present invention to be further understood and recognized, the detailed description of the present invention is provided as follows along with embodiments and accompanying figures. The concepts of the present invention can be embodied by various forms. Those embodiments are not used to limit the scope and range of the present invention.

[0029] The present invention provides a method for swallow safety monitoring and a device thereof. By means of the fundamental breath sounds, whether swallowing in a diet is normal can be monitored. Once an abnormal condition occurs, an alarm is submitted to caregivers for intervention.

[0030] First, please refer to FIG. 1, which shows a flowchart according to an embodiment of the present invention. As shown in the figure, the method for swallow safety monitoring is applied for tube feeding, the method comprises steps of: [0031] Step S1: Disposing one or more sound sensor at one or more chest location; [0032] Step S3: Sensing a breath sound at the chest location for generating a reference sound datum; [0033] Step S5: Sensing a plurality of sensing sounds at the chest location in a diet period, and generating a plurality of sound sensing data; and [0034] Step S7: Comparing the plurality of sound sensing data according to the reference sound datum and monitoring during said diet period.

[0035] Next, a device for swallow safety monitoring, that is, a device for achieving the method for swallow safety monitoring according to the present invention will be described. Please refer to FIG. 2, which shows a schematic diagram of a device according to an embodiment of the present invention. As shown in FIG. 2, the device for swallow safety monitoring 1 according to the present invention comprises one or more sound sensor 22, a timer 32, and a monitoring unit 42. In addition, the device for swallow safety monitoring 1 according to the present invention can further comprises a control unit 44 and a storage unit S. The sound sensor 22 is disposed at a chest location P. The timer 32 is connected to the sound sensor 22 and thereby synchronous with the sound sensor 22. The monitoring unit 42 is connected to the sound sensor 22 and the timer 32 and monitors the swallowing condition of a care receiver. Furthermore, the control unit 44 is connected to the monitoring unit 42, the timer 32, and the sound sensor 22, and the monitoring unit 42 is further connected with a feeding device Feed.

[0036] As shown in the step S1, according to the present embodiment, the sound sensor 22 is disposed at a single chest location P. Nonetheless, the present invention is not limited to the location. A plurality of sound sensors 22 can be disposed around the chest location P for increasing sensing accuracy, for example, at the breastbone, which is a flatter location on the chest. As shown in the step S3, the sound sensor 22 senses the fundamental breath sound at the chest location P in a non-diet period and hence giving a relatively normal breath sound as the reference sound. Then the sound sensor 22 can generate a reference sound datum, which is used as the monitoring standard for the monitoring unit 42. As shown in the step S5, the control unit 44 controls the timer 32 to start timing and controls the sound sensor 22 to start sensing. The timer 32 times in the whole diet period, which includes the time before, within, and after the diet period.

[0037] Thereby, the sound sensor 22 senses sound at the chest location P, for example, the bottom edge of the chest, in the whole diet period and generates a plurality of sound sensing data for further comparing by the monitoring unit 42.

[0038] As shown in the step S7, the monitoring unit 42 compares the received reference sound datum with the sound sensing data. According to the comparison result, the swallow sound can be monitored. Please further refer to FIG. 3, which shows a partial flowchart according to an embodiment of the present invention. As shown in the figure, the step S7 further comprises steps of: [0039] Step S72: Judging if one of the sound sensing data is different from the reference sound datum; [0040] Step S74: Submitting an alarm message; and [0041] Step S76: Continuing monitoring.

[0042] As shown in the step S72, the monitoring unit 42 compares each of the sound sensing data. By comparing each of the sound sensing data with the reference sound datum, whether each of the sound sensing data is abnormal can be judged. In other words, the reference sound datum is used as a threshold value. When the frequency or amplitude of one of said plurality of sound sensing data exceeds the threshold value, the step S74 will be executed to trigger the monitoring unit 42 to generate an alarm message. When there is no abnormal condition, namely, when the frequency or amplitude of one of said plurality of sound sensing data does not exceed the threshold value, the monitoring unit 42 continues monitoring and returns to the step S5. The storage unit S stores the reference sound datum, the plurality of sound sensing data, and the diet period.

[0043] The threshold value as described above can further be the standard value of personal swallow practice in rehabilitation. Extract the sound of swallow practice and compare it with the threshold value. When the frequency or amplitude of one of said plurality of sound sensing data exceeds the threshold value, the step S74 will be executed to trigger the monitoring unit 42 to generate an alarm message. When there is no abnormal condition, namely, when the frequency or amplitude of one of said plurality of sound sensing data does not exceed the threshold value, the monitoring unit 42 continues monitoring and returns to the step S5.

[0044] Moreover, as shown in FIG. 4, the device for swallow safety monitoring 1 according to the present invention can further comprises a transmission module 52 connected to the storage unit S for transmitting the reference sound datum, the plurality of sound sensing data, and the diet period to an electronic device EE. Given the fact that everyone owns a smartphone, people can know the diet condition of patients from the electronic device EE promptly. In addition, as shown in FIG. 5, the device for swallow safety monitoring 1 according to the present invention can further comprises a display 54 connected to the sound sensors 22 and the timer 24 for displaying the corresponding data of the sound sensors 22 and the timer 24. For example, the reference sound datum, the plurality of sound sensing data, and the timing information of the timer 24 can be displayed.

[0045] In the following, a flow chart of a method for swallow safety monitoring according to another embodiment of the present invention will be described. Please refer to FIG. 6. The process according to the present invention comprises steps of: [0046] Step S11: Disposing one or more sound sensor at one or more chest location; [0047] Step S13: Sensing a breath sound at the chest location for generating a reference sound datum; [0048] Step S15: Sensing a plurality of sensing sounds at the chest location in a diet period, generating a plurality of sound sensing data, sensing the horizontal angles of the sound sensor, and generating a plurality of sensing angle data; and [0049] Step S17: Comparing the plurality of sound sensing data according to the reference sound datum and monitoring during the time before, within, and after the diet period according to the plurality of sensing angle data.

[0050] Please refer to FIG. 7. The difference between FIG. 2 and FIG. 7 is that an angle sensor 24 is further disposed at the chest location P and connected to the monitoring unit 42.

[0051] In the steps S11 and S13, the execution methods are identical to the technology described in the step S1 above. Hence, the details will not be described again. In the step S15, in addition to monitoring the whole diet period, the sound sensor 22 is further adopted to sense the sound at the chest location P as well as using the angle sensor 24 to sense the body angle of the care receiver. Thereby, a plurality of sound sensing data and a plurality of angle sensing data are generated. For example, attaching the angle sensor 24 to the care receiver's shoulder, waist, or bed for sensing the body angle.

[0052] Please refer to FIG. 8. Compared to FIG. 3, the step S17 according to the method for swallow safety monitoring of the present invention further comprises: [0053] Step S172: Judging if one of the sound sensing data is different from the reference sound datum; [0054] Step S174: Generating a sound alarm message; [0055] Step S176: Judging if one of the angle sensing data exceeds the reference angle datum; [0056] Step S177: Generating an angle alarm message; [0057] Step S178: Continuing monitoring.

[0058] The step S172 adopts the same technology as the step S72. Hence, the details will not be described. In the step S172, when one of the sound sensing data exceeds the reference sound datum, the step S174 is executed; when one of the sound sensing data does not exceed the reference sound datum, the step S176 is executed. In the step S174, the monitoring unit 42 will generate a sound alarm message as the sound is abnormal. In the step S176, when the monitoring unit 42 judges that one of the angle sensing data exceeds the reference angle datum, the step S177 is executed; when the monitoring unit 42 judges that one of the angle sensing data does not exceed the reference angle datum, the step S178 is executed. Hence, the process returns to the step S15. In the step S177, the monitoring unit 42 will generate an angle alarm message as the angle is abnormal.

[0059] As shown in FIG. 9, the device for swallow safety monitoring 3 directly monitors non-tube-feeding people with dysphagia. Thereby, their swallowing conditions are monitored in a diet period for avoiding danger, such as dyspnea or food impaction caused by choking of food in the throat. Likewise, the device for swallow safety monitoring 1 monitors non-tube-feeding people by means of the steps S11 through S17. The sound sensor 22 acquires the reference sound datum. The monitoring unit 42 judges sensing sound according to the acquired reference sound datum. Meanwhile, the angle sensor 24 senses the body angle or bed angle of people for monitoring the swallowing of people. Besides, the present invention can be applied to home swallow rehabilitation of people.

[0060] To sum up, the present invention provides a method for swallow safety monitoring and a device thereof. By using monitoring unit 42 as an automatic assistive monitoring device, the following effects can be achieved: [0061] 1. Providing safety service by monitoring breath data before, within, and after a diet through the AI technology; [0062] 2. Providing personal precise medical and care mechanism; [0063] 3. Relieving long-term care loads of patients' family or caregivers; [0064] 4. Preventing infection caused by food backflow and reducing death caused by complications; and [0065] 5. Reinforcing personal swallow rehabilitation and improving living quality.

[0066] Accordingly, the present invention conforms to the legal requirements owing to its novelty, nonobviousness, and utility. However, the foregoing description is only embodiments of the present invention, not used to limit the scope and range of the present invention. Those equivalent changes or modifications made according to the shape, structure, feature, or spirit described in the claims of the present invention are included in the appended claims of the present invention.
