Abstract

The invention discloses a sleep apnea monitoring device which comprises a respiration sensor, a voltage signal amplifier, a rectifying circuit, a time discriminating circuit and a pulse generator. Compared with the prior art, a measuring system can be simplified, the volume and the weight of the monitoring device can be reduced, an easily operated portable device is provided for diagnosing and treating sleep-related breathing disorder, the sleep apnea monitoring device obtains characteristic pathological information of sleep apnea syndrome (SAS) in a simple way and provides an effective technical means for primary screening, general survey and monitoring of SAS.

Description

The apneic device of a kind of monitoring sleep

Technical field

The invention belongs to the medical monitoring technology, be specifically related to the apneic device of a kind of monitoring sleep.

Background technology

According to the diagnostic criteria that international medical community generally adopts, (sleepapnea syndrome, one of important criterion SAS) are that the patient surpasses 10 seconds breathing interruption times in sleep in 8 hours to sleep apnea syndrome.At present, the general sleep analysis monitor technology (Polysomnograhy that adopts, PSG) obtain this pathological information (Carskadon M, Dement WC.Normal human sleep:an overview.In:Kryger M, Roth T, Dement W, et al.Principles and practice of sleep medicine.Philadelphia:WB Saunders, 1994,3～15).The advantage of this method is the comprehensive physiological and pathological information that can obtain sleep disordered breathing; weak point is its equipment bulky complex; unsuitable portable application; the Sandman sleep-respiratory monitor that typical products such as U.S. Tyco company produce; this device has 64 transducing signal passages; the object of the present invention is to provide a kind of new technical scheme; its advantage is to obtain the feature pathological information of sleep apnea patient in easy mode, for sleep apnea syndrome primary dcreening operation and generaI investigation provide a kind of feasible technological means.

Summary of the invention

Realization the inventive system comprises the pick off [1] of detecting breathing process, the electronics device [2] that amplifies the respiration pickup signal of telecommunication, breath signal shaping circuit [3], breathing discriminator circuit break period [4], count pulse generator [5] and is used to connect the starting impulse generator [6] of stimulating apparatus.

[1] make the monitored target respiratory be converted to associated electrical signals, [2] improve the level of associated electrical signals by active device, [3] to be shaped as with the pulse width be the pulse train of feature, constant amplitude for the analog quantity signal of telecommunication that respiratory is relevant, [4] whether has the feature of sleep apnea syndrome in order to the respiratory of differentiating monitored target, [5] provide the quantitative information of patient's pathological characters, [6] are used to produce the electric pulse that starts aid.

Technical scheme of the present invention is compared with the prior art scheme, and its beneficial effect is, can the simplified measurement system, reduce the volume and weight of monitoring device, for primary dcreening operation, the generaI investigation of sleep disordered breathing and guard a kind of portable unit that is easy to use operation is provided.

The specific embodiment

Below in conjunction with drawings and Examples device of the present invention is done detailed description.

Respiration pickup [1] links to each other with the electronics device [2] that amplifies the respiration pickup signal of telecommunication, [2] outfan links to each other with breath signal shaping circuit [3], [3] outfan links to each other with differentiating the circuit [4] of breathing break period, [4] outfan links to each other with count pulse generator [5], link to each other simultaneously, as shown in Figure 1 with the starting impulse generator [6] that is used to connect stimulating apparatus.The breath signal shaping circuit, [3] be made of with resistance [9] operational amplifier [7], resistance [8], an end of resistance [8] links to each other with an input of operational amplifier [7], links to each other with an end of resistance [9] simultaneously, [9] the other end links to each other with the outfan of operational amplifier [7], as shown in Figure 2.Differentiate the circuit of breathing break period, [4] be made of with transistor [12] resistance [10], capacitor [11], an end of [10] links to each other with an end of [11], links to each other with the colelctor electrode of [12] simultaneously, [11] the other end links to each other with the emitter stage of transistor [12], as shown in Figure 3.The technology pulse generator, [5] are made of potentiometer [13] and operational amplifier [14], and the sliding end of [13] links to each other with an input of [14], as shown in Figure 4.Connect the starting impulse generator of stimulating apparatus, [6] are made of potentiometer [15] and operational amplifier [16], and the sliding end of [15] links to each other with an input of [16], as shown in Figure 5.
