Affiliated technical field

This utility model relates to the Medical Instruments technical field, specifically a kind of bed-wetting omen sensing device for portable enuresis warning and therapeutic equipment.

Background technology

Primary enuresis is a kind of commonly encountered diseases, the patient wets the bed through the sleeping at night of being everlasting, grade is waken up morning, find that just underwear and bed are wet by urine, oneself passes through completely without memory wetting the bed, cause heavy psychological burden and life stress for patient and family members thereof, there is no so far special effect medicine therapeutic both at home and abroad.According to bed-wetting association of WHO data, sickness rate reaches 10% during≤5 one full year of life, and adult people is 0.1～0.2%, ordinary person do not think sickness rate so high be unknown by the people because patient and kinsfolk protect emphatically privacy.

Domestic all alarm for bed wettings all are humidity sensors up to now, and it is 201020101996.2 " nocturia treating device " that the existing disclosed enuresis of Chinese patent is controlled instrument such as application number, and its sensor is wetness sensor; Application number is that " instrument for treating enuresis " its control device of 200520128919.5 is the wet induction apparatus of urine and intervalometer.Because the alarm for bed wetting of simple employing humidity sensor or instrument for treating enuresis are just to get involved after the bed-wetting beginning, because warning or treatment are not to carry out before bed-wetting occurring, so being helpless to the patient initiatively guards against a little in the peak period foundation of the long-pending urine of bladder, the generation that more impossible prevention is wet the bed can't resolve the trouble of wetting the bed and bringing.

Between human sleep period, whole cerebral cortex all is in inhibitory state, but wherein also has certain not suppressed and be in excited position, and this position is called as " warning point ".The warning point has two kinds of forms to be present in brain: a kind of is passivity warning point, can in the report of a gun, sleep soundly such as the soldier on the battlefield, supervisor issuing an order gently, springing straight up into the air immediately, it is just before a battle to drop into, mother of age of sucking can be sleeping at the station terminal of confused noise, baby in one's arms slightly has twisting, just can wake up moment and embrace lambling, and these passivity warning points need outside stimulus; Another kind is initiative warning point, namely do not need extraneous any stimulation or prompting, can automatically return to waking state from sleep state, the as above workman of class Three's running system, alarm clock calling training through the regular period, after initiative warning point forms, without alarm clock, also can in sound sleep, wake up when being on night shift to this.Should " warning point " in brain cell, be in the state of alert highly.When appearring in sleeping at night, the bed-wetting omen reminds or interventional therapy, can the Rapid Establishment passivity guard against point, prevention is wet the bed and is occured rapidly, help again to set up initiative warning point in the long-pending urine of bladder peak period, automatically from sleep, wake up when the time comes, urinate to this place of going, rather than in bed, enuresis is namely accused recovery from illness.

In recent years, United States Medicine scientific research personnel Wolfish N makes the electroencephalogram of whole sleep period to the enuresis infant and leads physiograph more and trace, discovery is provided at the δ ripple that high wave amplitude appears in electroencephalogram, tens seconds or a few minutes have been spent, the patient has just wet the bed in sound sleep, the long-pending urine of bladder peak period at a time when this.Cerebral tissue is human life activity's maincenter, internal organs, muscle, skin perception and revive ... all leading by cerebral tissue, since the inventor thinks that cerebral tissue provides the δ ripple of high wave amplitude, health just will inevitably react to some extent, clinical observation to this moment the patient occur that hypertension, heartbeat acceleration, rapid breathing, muscular tension increase, body is unpeaceful and a series of performances such as skin resistance reduction, omen sign is referred to as to wet the bed.The great majority of wetting the bed occur in front 1/3 stage of sleep, be at that time among the deep sleep of the 3rd～4 phase of non-eye movement sleep, the client can not perception to the sign of bed-wetting omen, if wakened this moment, must prevent to wet the bed and occur, through after a while intensive training and treatment, cure rate must obviously improve.It is not yet seen the enuresis is reminded and therapeutic equipment is equipped with bed-wetting omen sensor public technology and product news city.

Summary of the invention

Can not respond to the defective of bed-wetting omen in order to overcome existing enuresis warning and therapy equipment technology, the purpose of this utility model is that a kind of bed-wetting omen sensing device for portable enuresis warning and therapeutic equipment will be provided.This device comprises shell, time switch module, timing signal locking member and the bed-wetting omen switch module that is comprised of resistance 1 (R1), resistance 2 (R2), bed-wetting omen sensor (RDK), is connected the timing signal locking member between time switch module and bed-wetting omen switch module.
