The invention provides an emotion classification method and system based on facial blood flow distribution. The method comprises the steps of obtaining to-be-classified facial video data; selecting areas of two sides of the nose wing and the cheek of the face image data as ROI areas; determining the optimal pulse wave of the ROI; extracting basic features from the time domain and frequency domaininformation of the optimal pulse wave of the ROI; extracting facial blood flow distribution from the facial image data by utilizing the optimal pulse wave of the ROI; sequentially arranging the basicfeatures and the facial blood flow distribution of each piece of facial image data to form a facial blood flow distribution feature sequence as input feature data; and inputting the trained SVM model,and carrying out emotion classification. According to the method, physiological information such as facial blood flow distribution characteristics and the like is applied in the emotion classification process, so that emotion classification errors caused by the fact that a classification object masks the current emotion due to the fact that the classification object controls the facial expressionor controls the voice intonation of the classification object are avoided, and the emotion classification accuracy is improved.

The invention discloses a medical surgical mask. The mask comprises a mask body, a folding mechanism is arranged on the front face of the mask body, a nose folding wing attaching mechanism is installed on the front face of the mask body, connecting blocks are arranged on the two sides of the front face of the mask body, and ear hanging ropes are connected to the outer sides of the connecting blocks. Connecting mechanisms are arranged on the two sides of the mask body. With the arrangement of the nose wing attaching mechanism, when a user wears the device, the two sides of the nose wing can extrude a first attaching rod and a second attaching rod correspondingly, elastic forces are provided through a first connecting spring and a second connecting spring, so that the effect that the mask body is attached to the nose wing of the user is achieved; the elastic forces can be provided through the supporting springs, supporting between the face skin of a user and the mask body can be enhanced, the situation that a large gap is reserved between the face of the user and the mask body is avoided, and the protection effect is good.

The invention relates to a mouth-nose pad and a patient interface device, and relates to the technical field of treatment of respiratory related diseases. According to the mouth-nose pad, due to the fact that a nose opening in a nose structural body surrounds the lower sides of the nostrils of a wearer for ventilation, the mouth-nose pad does not need to cover the nose of the wearer, the size of the mouth-nose pad can be reduced on the whole, and the mouth-nose pad is smaller, lighter, not prone to generating claustrophobia and more comfortable to wear. A nose cushion part is adaptively attached to the periphery of the nares of the wearer for sealing, so that the nose wing of the wearer is not clamped, the wearing comfort is further improved, and the treatment effect and treatment compliance of the wearer can be improved. Besides, the nose structural body and the mouth structural body are respectively constructed, so that the inner cavity can bear higher pressure to meet the treatment requirements of different symptoms.
