Description
Technical field
This utility model relates to the instrument measuring electricity physiological signal of medical field, particularly to a kind of auditory meatus Surface Mount blood oxygen saturation monitoring instrument and system thereof.
Background technology
Oxygen be maintain human life important substance, human tissue cell carry out metabolism required for oxygen obtain from blood.After oxygen enters blood, nearly 2% is dissolved in blood plasma, and the oxygen in blood is mostly and is combined into HbO2 Oxyhemoglobin (HbO with the haemoglobin molecule in blood plasma2), it does not have the haemoglobin molecule being combined with oxygen is called reduced hemoglobin (HbR).Blood oxygen saturation is in order to represent the concentration of oxygen in blood, and the capacity of the HbO2 Oxyhemoglobin (HbO2) that it is combined by oxygen accounts for the percentage ratio of the capacity of whole hemoglobin (Hb).
Anoxia is the root causing numerous disease, and comparatively general disease such as chronic hypoxemia, the physiology such as brain is tired with cardiovascular blood supply insufficiency and post exercise and pathological phenomenon all have direct relation with human body oxygen content, the life of people is directly threatened time serious, blood oxygen saturation is the important physiological parameter that monitoring human body carries the ability of oxygen, estimates by human body can be carried the ability of oxygen by the monitoring of blood oxygen saturation.
The detection of blood oxygen saturation is divided into photochemistry and electrochemistry two class, i.e. noinvasive and two kinds of methods of invasive.Conventional invasive blood oxygen detection has two kinds of methods.One is carry out electro chemical analysis with blood gas analyzer after gathering blood of human body to measure oximetry value.This method needs, to pulse intubation puncture, human body has injury, and process is complicated, and analytical cycle is long, costly and also can not detect in real time continuously.Another way is exactly utilize the optical density of blood sample in spectrophotometer detection arterial blood, and calculates oximetry value on this basis.The method is still for clinical accurate measurement.Because invasive measuring method has above-mentioned shortcomings, so occurring in that non-invasive methods obtains having tried to of blood oxygen saturation.In transmission-type blood oxygen saturation detection technique, luminous tube and light sensor are placed on the both sides of human body, and need to be guaranteed on the upright position of human body both sides, and therefore, test position more options are at the end of limbs, such as finger, toe or ear-lobe.As it is shown in figure 1, luminous tube 1 is placed on the top of finger 2, light sensor 3 is arranged on lower section, and this makes the position of light sensor 3 place more single, it is impossible to the blood oxygen saturation at the detection multiple position of human body；Secondly transmission-type many employings clip or shell type are measured, and cause user constriction to a certain extent, and the long period wears, and affects blood circulation, causes and does not accommodate measurement error, have some limitations in application.Showing it addition, the oximetry value great majority that existing BOLD contrast detects are the display screens by instrument, measured or doctor obtain oximetry value only by observing display screen, can not realize the real-time remote monitoring to monitoring object.Once emergency case occurs, if distress signals can not be sent timely, the rescue opportunity of the best will be missed.
The instrument measuring and recording blood oxygen levels and blood oxygen trendgram in the market continuously is few, is more the device measuring blood oxygen levels in real time.
