Description

The device of prevention sleep sudden death

Technical field

This utility model relates to a kind of device of the sudden death that prevents to sleep, and in particular, relates in particular to a kind of device of the prevention sleep sudden death of judging by the blood oxygen saturation that detects the sleeper.

Background technology

The sleep sudden death generally refers to obstructive sleep apnea syndrome, is called for short OSAS, prevalence in the crowd is higher, is about 2%～4%, and men and women's incidence rate is about 6.3:1, be common in 40～70 years old overweight people, the over-65s prevalence can reach 20%～40%.The childhood period because tonsil and adenoid vegetation, also be this syndromic age group occurred frequently.OSAS is one group of proemial sleep disordered breathing disease, easily complicated by arrhythmia, hypertension even respiratory failure or sudden death.The whole world nearly 3000 people every day of elder generation die from primary disease.Therefore, strengthen the early discovery of obstructive sleep apnea syndrome, most important in the timely discovery that in time occurs being critically ill.But also there is not now a kind of effective detecting instrument, can the human body in the sleep procedure be detected in real time, when the detected person has the sign that the sleep sudden death occurs, stimulate it is come to life the generation of the sudden death phenomenon of avoiding sleeping by physical property from the deep sleep.

Sleep sudden death is sleep apnea syndrome, claims again sleep apnea low-ventilatory syndrome to refer to every night in 7 hours sleep procedure that asphyxia shows effect more than 30 times or apnea hypopnea indexes (AHI) 〉=5 time/hour and with the clinical symptoms such as drowsiness repeatedly.And descend 〉=4% with blood oxygen saturation than foundation level.Blood oxygen saturation (SO2) is the percentage ratio that is accounted for whole combinative hemoglobin (Hb) capacity in the blood by the capacity of the HbO2 Oxyhemoglobin of oxygen combination (HbO2), and the blood oxygen saturation of normal human's arterial blood is 98%, and venous blood is 75%.This shows, whether as long as can measure the interior blood oxygen saturation (SO2) of human body, just can dope the sleeper has the trend that the sleep sudden death occurs.

Summary of the invention

This utility model is in order to overcome the shortcoming of above-mentioned technical problem, and a kind of device of the prevention sleep sudden death of judging by the blood oxygen saturation that detects the sleeper is provided.

The device of prevention sleep sudden death of the present utility model comprises the oximetry sensor and the circuit part that place the human test to point; Its special feature is: described circuit part comprises arithmetic control circuit, electric-shocking circuit and warning circuit, and electric-shocking circuit, warning circuit all are connected with the outfan of arithmetic control circuit.

Oximetry sensor points to obtain the size of blood oxygen saturation numerical value by the test of human body, arithmetic control circuit is realized the detection of blood oxygen saturation and the output of alarm signal, when the sleeper has that sleep sudden death is ordered about or when being in sleep sudden death state, can send alarm signal, in order to cause household's attention on every side.Electric-shocking circuit is used for the output electric shock signal, is used for sleeper's electric shock is waken up.

The device of prevention sleep sudden death of the present utility model, described warning circuit is by acoustical signal warning circuit and light alarm the electric circuit constitute.Adopt acoustical signal and optical signal to unite the form of warning, easier together household's attention on every side in order to wake the sleeper, prevents its sleep sudden death.

The device of prevention of the present utility model sleep sudden death, described oximetry sensor and circuit part all be arranged at test the clamp body that finger matches on.Like this, whole clamp body has just had blood oxygen saturation and has detected and warning function, during sleep it is enclosed within on the finger, can effectively avoid the sleep sudden death.

The device of prevention sleep sudden death of the present utility model, described oximetry sensor is arranged on the clamp body, and circuit part is arranged in the watchcase; Oximetry sensor is connected by signal transmssion line with circuit part.The device of the prevention sleep sudden death of this form adopts the wrist-watch form, realizes the detection to the human body blood oxygen saturation, and produces the function of warning, electric shock.

The beneficial effects of the utility model are: the device of prevention sleep sudden death of the present utility model, testing circuit can be realized measurement to the blood in human body in oxygen saturation by oximetry sensor, and can have that sleep sudden death is ordered about or when being in sleep sudden death state the sleeper, send alarm signal, cause household's attention on every side.Avoided the generation of user sleep sudden death phenomenon.

The device of prevention sleep sudden death of the present utility model, before dying suddenly, patient can more in time send early warning, remind patient or household, stop dead generation, because the obstructive sleep apnea syndrome patient can easily be ignored by the patient without any symptom, or the patient not knows, this wrist-watch can find in time that there is the disease of hiding in the patient, because in time find, the patient can be treated timely, avoid dead generation, therefore, the life wrist-watch is one, and the main equipment of hospital is not suitable for domestic. applications by revolutionary invention, the birth of life wrist-watch, solved this difficult problem, therefore be worthy to be popularized.The device of prevention of the present utility model sleep sudden death also can with oximetry sensor and circuit part concentrated setting on clamp body, not only can effectively prevent the sleep sudden death, and after wearing, can not affect rest.
