Problems solved by technology

[0003] However, this method requires the use of sensors that can collect signals of maternal abdominal uterine contractions, and the sensors must be placed in the obstetric abdomen, which is inconvenient to use
Moreover, it is required that the collection of uterine contraction pressure must be reliable, otherwise the feedback effect will be poor, but this is not so easy for pregnant women who are in pain

Embodiment 1

[0043] refer to figure 1 , the present embodiment provides a method for controlling pain relief based on facial image recognition, characterized in that it comprises the following steps:

[0044] A1. Collect facial images at specified time intervals;

[0045] A2. Analyze the analgesic waveform type corresponding to the current facial image;

[0046] A3. According to the currently output analgesic waveform type, combined with the analgesic waveform type corresponding to the current facial image analyzed in step A2, update the output of the analgesic waveform.

[0047] The invention patent CN102940934B with the authorized announcement date of November 19, 2014 provides a biofeedback physical analgesia device for childbirth, which discloses a configuration method of analgesic waveform:

[0048] "Step 31: Set the shape parameters of the basic waveforms of each combination of the low-frequency modulation wave group;

[0049] Step 32: Set the combination order of the basic wavefo...

Embodiment 2

[0071] refer to image 3 As shown, the difference between this embodiment and Embodiment 1 lies in the improvement of the feedback control method, which is characterized in that it also includes the step of setting a timer Tb, which is the minimum continuous output time timer of the same type of analgesic waveform .

[0072] Updating the output of the analgesic waveform in the step A3 also includes: if the analgesic waveform type corresponding to the current facial image is not the same as the currently output analgesic waveform type, judging the continuous output of the currently output analgesic waveform Whether the time is greater than the timer Tb;

[0073] If yes, update the output type of the analgesic waveform to be the analgesic waveform type corresponding to the current facial image category, and the timer Tb restarts;

[0074] If not, keep the output type of the analgesic waveform unchanged, and the timer Tb continues.

[0075] In this embodiment, when facial imag...

Embodiment 3

[0077] refer to Figure 4 As shown, the difference between this embodiment and Embodiment 2 lies in the improvement of the feedback control method. It is characterized in that the output of updating the analgesic waveform in the step A3 also includes: if the current output of the analgesic waveform continues The output time is not greater than the timer Tb, and it is judged whether the analgesic waveform category corresponding to the facial image analyzed within the specified time exceeds the predetermined number of times with this same number of times;

[0078] If yes, update the output type of the analgesic waveform to be the analgesic waveform type corresponding to the current facial image category, and the timer Tb restarts;

[0079] If not, keep the output type of the analgesic waveform unchanged, and the timer Tb continues.

[0080] In this embodiment, even if the output duration of the analgesic waveform does not reach the minimum time requirement Tb before the judgmen...

Abstract

The invention provides an analgesia control method based on facial image recognition. The analgesia control method is characterized by including the following steps: collecting facial images at specific time intervals; analyzing analgesia waveform types corresponding to current facial images; updating output of analgesia waveforms. The invention further provides an analgesia control device based on facial image recognition. The analgesia control device comprises a feedback unit. The analgesia control device is characterized in that the feedback unit comprises a facial image collection module, a facial image classification module and a waveform control module. Natural expression display of a puerpera at a pain stage is utilized, so that the whole feedback process is enabled to be more natural; other equipment does not need to be adhered on the puerpera, so that other influence on the puerpera is avoided, and the whole feedback process is enabled to be more convenient; some interaction and interestingness can be added, so that tense mental mood of the puerpera is relieved, relieving of delivery pain is facilitated, and natural delivery is promoted.

Description

technical field [0001] The invention relates to the field of medical analgesia, in particular to an analgesia control method and device based on facial image recognition. Background technique [0002] In the medical pain index, labor pain is second only to burn pain. According to statistics, about 44% of primiparas feel pain during childbirth. In the current labor analgesic methods and devices, the judgment of the degree of labor pain is generally based on the strength of uterine contraction activity or some other related indicators. The invention patent CN102940934B with the date of authorization announcement on November 19, 2014 provides a biofeedback physical labor analgesia device, which uses uterine contraction pressure and maternal hand pressure as the basis for electric stimulation wave group adjustment. The automatic identification of uterine contractions can realize the automation of labor analgesia, which can reduce the workload of medical staff, reduce the waiti...
