Problems solved by technology

[0009] The technical problem to be solved by the present invention is to provide a method, device and application for detecting respiratory effort during sleep. By adopting the method, device and application of the present invention, non-invasive detection of respiratory effort can be realized, which overcomes the limitations of existing esophageal pressure detection. Too much load brought by the patient, not enough to feel discomfort

Embodiment 1

[0024] In this case, the micro-motion sensitive mattress sleep monitoring system (MSMSMS) was used to perform synchronous sleep monitoring on 22 patients suspected of having sleep apnea. The patients were 31-60 years old and weighed 75-96kg.

[0025] The model of the micro-motion sensitive mattress sleep monitoring system (MSMSMS) used is SRM-6000; its structure diagram is shown in Figure 3. In this example, the fretting sensitive mattress is longitudinally provided with four independent sensing areas, and the four sensing areas correspond to the head, chest, buttocks and lower limbs of the human body respectively, and each sensing area is an independent elastic fluid bladder , the capsule is filled with fluid with a set pressure, the fluid capsule communicates with the micro-pressure / electricity converter through the guide hole, the bottom surfaces of adjacent fluid capsules are connected to each other, and the micro-pressure / electricity conversion sensor at the detection part...

Embodiment 2

[0046] In this example, the result of detection of respiratory effort during sleep by the method of Example 1 is used to identify Respiratory effort-related arousal (RERA) during sleep.

[0047] Respiratory exertion arousal (RERA) is recognized when the ballistocardiogram amplitude or its integrated value is progressively increased in relation to respiration, followed by arousal.

[0048] When the sleep ballistocardiogram shows a significant increase in heart rate or a high-frequency oscillation related to breathing, it can be identified as sleep micro-awakening when the duration is 3-14 seconds. This judgment method is compared with the EEG method, and the results are highly consistent.

[0049] The above judgment method was compared with the gold standard esophageal pressure measurement method for the determination of RERA, and the two were significantly correlated, but esophageal intubation could be avoided.

Embodiment 3

[0051] The structure of the fretting-sensitive mattress-type sleep monitoring system used in this example is shown in Figure 4: the elastic mattress includes four air-permeable vertical partition pads: head pad 11, chest pad 12, buttock pad 13. The subdivision pads 14 for the lower limbs, the adjacent side walls (such as 11a, 12a) of the two adjacent subdivision pads (such as 11, 12) are close together, and the bottom pad surfaces (such as 11b, 12b) are connected to each other, and the sensor It is the sealing elastic bodies 21, 22 filled with fluid, and the elastic bodies are equipped with sensing elements 21a, 22a which can sense the fluid pressure change in the sealing cavity, and the output ends of the sensing elements are connected with the data processing computer through amplifiers and A / D converters, The sensing and sealing elastic bodies 21 and 22 are arranged on the mattress where they can sensitively sense the corresponding information of the detected parts of the hu...

Abstract

The invention relates to a method for detecting the breath force in sleep, relative device and application. Wherein, the invention is characterized in that: it uses pressure micro sensor to obtain the micro signals of heart beat, breath, and body movement in sleep, to input them into computer to be processed to form heart impact diagram; and uses the breath amplitude or its integral value of sleep heart impact diagram to represent breath force state, and uses the said breath amplitude or its integral value as the base. The invention can realize non-invasion detection on target.

Description

technical field [0001] The invention belongs to a method, device and application for acquiring data related to judging human diseases, in particular to a method, device and application for detecting human sleep breathing effort. Background technique [0002] The breathing effort of the human body during sleep is related to some diseases, so it can be used as data related to judging human diseases. [0003] For example, for sleep apnea hypopnea syndrome (Sleep Apnea Hypopnea Syndrome, SAHS), the diagnosis method is to obtain the patient's sleep structure and sleep breathing events throughout the night, and then obtain important diagnostic data of sleep apnea hypopnea syndrome - respiratory disturbance index, etc. Quantitative indicators, and use these quantitative indicators to determine the condition. [0004] There are different types of respiratory events. The special report of the American Academy of Sleep Medicine believes that for the classification of respiratory even...
