Description
Technical field
The invention belongs to a kind of medical monitoring device, be specifically related to a kind of sensing device that is used for monitoring sleep status and respiration disorder event.
Background technology
According to studies confirm that in recent years, the asphyxia that the people occurs in sleep is now as closely related with generation, the development of human numerous disease.Sleep apnea for example, its pathology and physiological unification show as: hypoxemia takes place during sleep repeatedly, hypercapnia, blood pH decline is lost compensatory, these three kinds of phenomenons in sleep repeatedly generation can cause a series of pathophysiological changes in the health, relate to the various clinical subject, therefore the application of sleep monitor quasi-instrument is more and more in recent years, sleep disordered breathing is a general orientation of present clinical sleep monitor, this monitoring instrument has two classes: a class is sleep analysis monitor instrument (Polysomnography, PSG), need monitor a plurality of parameters in hospital during monitoring, monitored person's head, facial, health need be laid a plurality of electrodes and be connected multiple conducting wires and pick off with extremity, complicated operation, want medical personnel on duty, the measured has been constituted sizable physiology and psychological burden, easily disturb sleep; Another kind of is portable polysomnograph, can post electrode relief measured in hospital and carry the sleep of going home, and next day recording box is delivered to hospital's playback again and analyzes result's report.Because traditional method all is to differentiate Sleep architecture by surveying EEG signals, so all need to attach more electrode on human body, not only to measured's sense that brings inconvenience and discomfort, and EEG signals is more vulnerable to interference than other signal; The portable type that has just screen(ing) machine needn't be pasted electrode for encephalograms on one's body the measured, but must breathe by being contained in other sensor measurement nose air-flow on the human body, breast, lower limb is moving etc., use inconvenience, and the omission electrode is a cost with remarkable reduction analytical accuracy.
Since 1996, present patent application inventor finds through experimental study: between the cardiac cycle in Sleep architecture and when sleep goodish coupled relation is arranged, the Sleep architecture result who obtains with cardiac cycle analysis by shooting and contrast with the result of eeg analysis Sleep architecture and to have average coincidence rate to reach 85% concordance.The moving signal of lower limb also can reflect the sleep state of human body in addition, therefore in 03153623.8 patent application, a kind of device that moves and change the realization analysis of sleeping structure by detection cardiac cycle, breathing, body is disclosed, this device is the mattress that is combined by a plurality of fluid cell, the measured lies on the mattress, the measured's who senses by the minor variations of fluid cell pressure cardiac cycle, breathing, the moving information of body provide data with these heat transfer agents for carrying out analysis of sleeping structure.This patent application can alleviate various electrodes and be connected lead and do not accommodate mental workload to what the measured brought, but owing to need lie on air-locked fluid cell with the measured, can make health feel uncomfortable and the influence sleep.
Summary of the invention
The technical problem to be solved in the present invention is to overcome above-mentioned deficiency, provides a kind of and do not need to paste electrode on human body, connects lead, and can make the measured feel the more comfortable monitoring sleep status and the sensing device of respiration disorder event.
The technical scheme that addresses the above problem is (referring to implementing illustration): the present invention is provided with elastic bed mattress (1), pressure transducer, it is characterized in that: described mattress (1) comprises and is no less than two gas-pervious vertical partition pads (11,12,13,14), adjacent two subregion pads (11,12) adjacent wall (11a, 12a) draw close, heelpiece face (11b), (12b) interconnect, described pick off is for being full of fluidic sealing elastomer (21,22), elastomer is equipped with the sensing element (21a that energy induction sealing cavity fluid pressure changes, 22a), the sensing element outfan is connected with data processor by lead, and described sensing sealing elastomer (21,22) is arranged at can the sensitive position of responding to the detected position of human body corresponding information on the mattress.
Further scheme is: described mattress (1) comprises subregion pad (12) that supports human chest and the subregion pad (14) that supports human body lower limbs at least, go up the position of close human heart at chest subregion pad (12), and be respectively arranged with described sensing sealing elastomer (21), (22) on the lower limb subregion pad (14).
Further scheme is again: the fluid that described sensing sealing elastomer (21,22) lining is full of is a fluid oil.
Preferred version is: the fluid that is full of in the described sensing sealing elastomer is liquid silicone oil.
Above-mentioned vertical partition pad is meant the subregion pad of the direction that couches along human body.
Operation principle of the present invention is: the subregion pad can be separated with different detection positions, make the induced signal of each subregion pad relatively independent, prevent the phase mutual interference, describedly be full of fluidic sealing elastomer inner chamber and can form corresponding stress, the measured lies on the gas-pervious elastic bed mattress, by being contained in the information that elastomer internal pressure that the sensing element induction human body that detects on the sealing elastomer of position causes because of heartbeat, breathing, body are moving etc. changes, this pressure change signal changes the signal of telecommunication into and is input to data processor and carries out date processing.
The present invention adopts common ventilative elastic bed mattress to support human body, need only be with the corresponding information of the sensing sealing elastomer of small size induction related parts of human body, overcome original fluid cell and should be used to respond to human body information and be used to support human body again and cause the discomfort that contacts with the human body large tracts of land and bring to the measured.
Further scheme is provided with signals such as sensing sealing elastomer (21), (22) can be used for measuring impacts of human body breast, lower limb impact, respiratory wave, the upper body is moving, lower body moves at chest subregion pad and lower limb subregion pad position, and then provides analytical data for sleep movement obstacles such as cardiac cycle, breathing rate, Hypnogram, sleep-respiratory event analysis, Periodic leg movements diseases.
Has the advantage of sensing Ling Dugao when being full of fluid oil in the further again scheme sensing sealing elastomer of the present invention.
