- the control unit 29 Upon detecting that one of the patient names displayed in the patient selection box 43 is selected by the instruction unit 37 (for example, patient A) (YES in step S60), the control unit 29 sends to the server 14 The access is made and the recording date / time information of the body sound data corresponding to the patient A is downloaded from the server 14 (step S61). A list of recording date / time information of patient A is displayed in the recording date / time selection box 44 (step S62).
- the instruction unit 37 detects that one recording date / time has been selected from the recording date / time information list (step S63), and then detects that the analysis button 45 has been clicked (step S63).
- the biological sound digital data corresponding to the selected recording date and time is downloaded from the server 14 and stored in the memory unit 31 (step S65).
- the swallowing sound data of the healthy person is downloaded from the server 14 and stored in the memory unit 31 (step S66).
- the control unit 29 extracts swallowing sound data from the patient's body sound digital data stored in the memory unit 31 (step S67), and is performed during recording based on the extracted swallowing sound data.
- the number of swallows is calculated (step S68).
- a signal that is below the maximum volume of general swallowing is continuously swallowed for a predetermined time or longer.
- the number of swallows can be calculated by extracting as the bottom and adding this number. This mechanism will be described with reference to FIG.
- Fig. 6 (a) is a diagram showing an example of an analog waveform of biological sound data obtained from a sleeping patient
- Fig. 6 (b) is an enlarged view of a wavy line portion shown in Fig. 6 (a). is there.
- the patient produces sounds such as sleep, sleep, swallowing saliva, and the force S of bruxism.
- the feature is that the volume is lower than the operation of. For this reason, as shown in FIG. 6 (b), when the maximum volume value for swallowing is A, it can be determined that swallowing occurs if a signal equal to or lower than this volume value A continues for a predetermined time or more.
- swallowing is a movement that continuously performs the process of feeding from the mouth to the pharynx (oral stage), the action of feeding from the pharynx to the esophagus (pharyngeal stage), and the action of feeding from the esophagus to the stomach (esophageal stage).
- oral stage the action of feeding from the pharynx to the esophagus
- esophagus the action of feeding from the esophagus to the stomach
- the maximum volume value in the silent state is assumed to be B, and a signal below the volume value B is continuously generated for the predetermined time or longer (the first silent state). If a signal with a volume value A or less continues for a predetermined time or more and then a signal with a volume value B or less continuously occurs for a predetermined time or more (second silence state), this may be determined as swallowing.
- control unit 29 calculates the number of swallows performed during recording. Then, the number of swallowing of the obtained patient is compared with the number of swallowing of a healthy person (step S69).
- the human body normally performs secretion activities such as saliva as physiological functions, and swallowing activities to carry the saliva into the body. Therefore, within a certain period, the amount of saliva secreted between healthy and non-healthy individuals is considered to be the same amount. Therefore, when the number of swallowing by the patient is smaller than the number of swallowing by the healthy person, it can be determined that the patient swallows the saliva without swallowing, that is, aspiration occurs. For example, the number of swallows per hour by the patient and the number of swallows by a healthy person are compared. If the number of swallows is extremely less than that by a healthy person, it is determined that the patient has aspiration.
- a threshold value indicating whether the subject is a healthy person or a non-healthy person is determined in advance from the standard deviation, and if this threshold value is compared with the number of swallowing times of the patient, the patient's condition may be included in the stool. Can be judged.
- step 69 the number of swallows of the patient and the healthy person is compared, and if it is determined that the number of swallows of the patient is less than the number of swallows of the healthy person (YES in step S70), the patient is erroneously displayed on the display unit 36. A message indicating that the person is swallowing, that is, an unhealthy person is displayed (step S71). If it is determined that the number of swallows by the patient is the same as the number of swallows by the healthy person (NO in step S70), the display unit 36 displays that the patient has not swallowed, that is, is a healthy person. (Step S72).
- a playback button is displayed on the display unit 36 shown in FIG. 4, and when the instruction unit 37 detects that the playback button has been clicked, digital data is downloaded from the server 14 and D / A conversion is performed. It may be configured to output from the speaker 35 after analog conversion by the unit 34. This allows doctors to view the patient's swallowing sound before analyzing the digital data, thus preventing accidental operations of accidentally analyzing other data.
- the state of the patient's cough based on the patient's body sound digital data. It is important for diagnosis to measure swallowing information and cough information together, and this is possible in the present invention. This is called occult aspiration, meaning that it is not known that aspiration is occurring. Cough continues even if aspiration occurs If you have a cough, if you do not have a cough, you do not know that you are aspirating and you cannot detect it. In particular, even if aspiration occurs at night, even if cough occurs, if it is light, it will not be recognized and will become an inapparent aspiration.
- saliva secretion ability and secretion status of the subject it is preferable to take into consideration the saliva secretion ability and secretion status of the subject. Specifically, when comparing the number of swallows, information such as salivary gland diseases can be used as a parameter. For example, the amount of saliva at rest known as a saliva secretion test can be used as a useful parameter.
- the body sound data is preferably acquired when the patient is at rest. More preferably, the acquired body sound data includes sleep stage data. It is known that reflexes such as swallowing reflex and cough reflex are related to sleep stages such as REM sleep and non-REM sleep. Therefore, it is very important to grasp at which sleep stage the acquired biological sound data is acquired in order to understand the state of the subject. For this reason, in the present invention, it is preferable to use both body sound data acquisition and sleep stage grasp. In addition, as a method of grasping the sleep stage, EEG, muscle It is possible to use known means such as electrograms and eye movements.
- the force server 14 when analyzing the digital data of the patient, is configured to determine whether or not the patient is aspiration by comparing with the data of the healthy person.
- Data of a healthy person (a patient who causes aspiration) may be stored, and the state of the patient may be judged by comparing with the data. It is also possible to learn the data of patients diagnosed in the past using a neural network and use it for the next diagnosis.
- the patient's biological information is not limited to the microphone.
- an acceleration sensor is arranged in the patient's throat, and the biological information is acquired by detecting the movement of the throat by the acceleration sensor.
- electrodes may be arranged at or around the throat, and biological information may be obtained by detecting a minute current generated during muscle contraction of the throat.
