Please refer to FIG. 1, which is a block diagram of a wearable salivation monitoring device according to a first embodiment of the present invention. As shown in FIG. 1, the wearable salivation monitoring device 1 includes a mask 10, a saliva receiving container 20, a saliva volume detection module 30, a reminder module 40, and a control module 50 electrically connected to these modules. The saliva receiving container 20 may be located at the periphery of the left and right corners of the user and extended to the lower edge of the lips to receive the saliva 21 flowing down the corner of the mouth. The saliva receiving container 20 has an arc-shaped slot corresponding to the lower lip of the face, and the opening faces the lips, and the saliva 21 flows along both ends of the saliva receiving container 20 toward the center (lower position) of the saliva receiving container 20.

In order to prevent the saliva receiving container 20 from being filled with saliva 21 and overflowing, a saliva volume detection module 30 may be provided near the saliva receiving container 20 to detect the total saliva volume 31 of the saliva 21 received by the saliva receiving container 20. The control module 50 can store the volume of the saliva receiving container 20 in advance and compare the total saliva volume 31 with the volume, or can set the saliva volume detection module 30 near the top of the saliva receiving container 20 to measure the saliva receiving container The liquid level of the saliva 21 in 20 is about to be or already full, the control module 50 can control the reminder module 40 to notify the user.

The saliva volume detection module 30 can detect the total saliva volume 31 of the saliva 21 received by the saliva receiving container 20 within a period of time, and the control module 50 can obtain the total saliva volume threshold value 51 corresponding to the length of time and the time The threshold value 51 of the total saliva volume detected within the length is compared. When the control module 50 compares that the total saliva volume 31 is greater than the total saliva volume threshold 51, the control reminder module 40 outputs a swallowing reminder signal 41 to remind the user to swallow saliva to avoid the user from choking. The control module 50 can further calculate the flow rate of the saliva 21 according to the length of time the saliva volume detection module 30 performs the detection and the total amount of saliva 31 detected, and it is worth knowing the saliva 21 based on the difference between the multiple flow rates detected at different time points The flow rate of the fluid is compared with the calculated flow rate of saliva 21 and the pre-stored total flow rate threshold. If the flow rate of saliva 21 is greater than the total flow rate threshold, the control module 50 can determine that the user has a swallowing disorder. The above-mentioned total saliva volume threshold value 51 and the total flow velocity threshold value can be values that change with time, for example, the control module 50 or the storage module can pre-store a plurality of total saliva volume threshold values 51 and a plurality of respectively corresponding to different time points Threshold of total flow rate.

The wearable salivation monitoring device according to claim 1, wherein the control module calculates a left flow velocity of the saliva flowing down the corner of the left mouth based on the time length and the amount of the left saliva, whether the left flow velocity is greater than one For the left flow threshold value, the control module calculates a right flow velocity of the saliva flowing down the right mouth corner based on the time length and the right saliva volume, and compares whether the right flow velocity is greater than a right flow velocity threshold value. A salivation monitoring method suitable for the wearable salivation monitoring device according to claim 1, the method comprising: (a) through the left saliva volume detection module provided near the left mouth corner to the left inner side of the saliva receiving container Detecting the saliva, and detecting the saliva on the right inner side of the saliva receiving container through the right saliva volume detection module provided near the corner of the right mouth; (b) the control module determines the left saliva volume detection Whether the module detects the left saliva volume, and the control module determines whether the right saliva volume detection module detects the right saliva volume. If the left saliva volume is not, perform step (a) the left saliva volume detection For module detection, if the right saliva volume is no, perform step (a) detection of the right saliva volume detection module, if the left saliva volume is yes, perform step (c), if the right saliva volume detection module If yes, perform step (d); (c) The control module compares whether the left saliva volume is greater than the left saliva volume threshold within the time length, if not, execute step (a) the left saliva volume The detection of the detection module, if yes, step (e); (d) the control module compares whether the right saliva volume is greater than the right saliva volume threshold within the time length, if not, execute step (a) If it is detected by the right saliva volume detection module, step (e); and (e) the control module controls the reminder module to output the corresponding swallowing reminder signal to remind the user to swallow saliva. The salivation monitoring method according to claim 4, further comprising the following steps: storing a plurality of the left saliva volume threshold values and a plurality of the right saliva volume threshold values corresponding to a plurality of time periods by a storage module; and by the control The module determines the time period at which the left saliva volume detection module and the right saliva volume detection module perform detection, and accordingly obtains the left saliva volume threshold value and the corresponding time period from the storage module Threshold of right saliva volume. The salivation monitoring method according to claim 4, further comprising the following steps: comparing whether the total saliva volume of the sum of the left saliva volume and the right saliva volume within the time length is greater than a total saliva volume threshold, if If no, go to step (b), if yes, go to step (e). The salivation monitoring method according to claim 4, further comprising the following steps: detecting a pH value of the saliva in the saliva receiving container through a pH value detection module; and determining the pH value by the control module When the value of a pH range is exceeded, the reminder module is controlled to output a corresponding signal of an acid-base abnormality.
