Description
Technical field
Patent of the present invention belongs to medical health field, is specifically related in a kind of sleep and breathes the monitoring device with heartbeat. .
Background technology
The research that the research of sleep-respiratory is directly connected to sleeping disorders, therefore sleep-respiratory becomes the topic comparing care in sleep medical science. At present, to be called sleep apnea low syndrome (SAHS) in widespread attention for one. This kind of illness is comparatively common, and its clinical manifestation is snoring, breathlessness, daytime is drowsiness. Sleep-respiratory syndromes causes long-term sleep hypoxemia and hypercapnia, extends the complication causing each system of whole body with the course of disease, such as cardiovascular system diseases, respiratory system disease, Digestive tract and urinary system and metabolic disturbance. Find through investigation to breathe and heartbeat suddenly to stop lethal be not example, it greatly threatens the healthy of people, particularly the elderly and intelligentsia. Reasonably diagnosis and treatment as early as possible, the quality of life that can improve patient prevents the generation of various complications, significantly improves the survival rate of patient. Therefore, to the monitoring of sleep-respiratory it is the first step of prevention and diagnosis and treatment sleep disordered breathing. How can forecast the state of an illness even in advance in time and avoid the generation of tragedy, seem most important.
At present, breathe heartbeat inspecting and mainly contain pressure application, warming method, air-flow method inductance method, thorax impedance method. Pressure application needs special signal pickup assembly, such as national inventing patent: air-cushion type human body respiration, heartbeat and stand up air cushion described in automatic monitoring device and monitoring method (200610097472.9), big area uses air-locked material, seriously affects the sleep quality of patient. Warming method and air-flow method utilize the temperature sensor being placed on nasal cavity place or baroceptor to obtain breath signal, and contact human body skin often brings discomfort to tester. Thorax impedance method causes Thorax volume to change according to human body respiration motion, thus causes thorax impedance change to obtain breath signal, and this device needs to carry exciting current at human chest adhesive electrode toward chest, and long-term adhesive electrode can injure the skin of tester.
Publication number is CN101632585A, and its publication date is ground national inventing patent on January 27th, 2010 open a kind of " respiration monitoring device of knitted structure ", and described device utilizes pressure inhibition effect collection human abdomen's respiratory movement signal of electro-conductive fiber.This device has the soft and ventilative feature of knitted fabrics, suitable long term monitoring. But, its electro-conductive fiber adopts Stainless Steel Fibre, copper fiber or silver plated fiber, and material self character determines that the linear lag of this measuring apparatus is poor, cannot breathe and heartbeat signal by Measurement accuracy.
Publication number is CN201759559U, and its publication date is the patent disclosure one " monitoring device of the patient respiration rhythm and pace of moving things based on electromagnetic sensor " of on 03 16th, 2011, and described device comprises electromagnetic sensor, inductance measurement instrument. Electromagnetic sensor is the coil such as outer peripheral gear shape being made up around a circle of a conductor loop, and two wiring ends of coil are connected with the input terminus of inductance measurement instrument. This sensor is placed on human body front, because the enlargement and contraction of chest muscle causes the enlargement and contraction of sensor when breathing, thus to reflect, measured breathes the rhythm and pace of moving things by the inductance value recorded. This device subsequent conditioning circuit is complicated, and tolerance range is not high.
Publication number is CN201752414U, and its publication date is the patent disclosure " a kind of sleep breath monitoring cap " of on 03 02nd, 2011, and this device is made up of cap body and electrode and cable, and said electrode sews in cap body, and cable is fixed on electrode. Electrode is directly fixed in cap body by device, then cable and electrode is fixed, and does not so just need such adhesive plaster in the past that on skin or on hair, attachment of electrodes is reduced monitoring painful. But measured needs to be branded as to test, it is not suitable in sleep and monitors, and the symptom of various respiratory disease only just can be monitored at night.
