Description
技术领域：Technical field:
本发明涉及一种袜式新生儿血氧饱和度监测装置，属生物医学工程技术领域。The invention relates to a sock-type neonatal blood oxygen saturation monitoring device, which belongs to the technical field of biomedical engineering.
背景技术：Background technique:
新生儿血氧饱和度监测可准确、直接、实时、无创地反映新生儿氧合状态及酸碱平衡。临床研究结果表明，血氧饱和度对预测新生儿窒息的敏感性、准确率有较高的关联性。新生儿血氧饱和度监测是新生儿护理过程中比较可靠的诊断呼吸窘迫的手段，已有很多临床研究证明并支持上述结论。以新生儿血氧饱和度为阈值对诊断新生儿异常的敏感性、特异性、阳性预期值及阴性预期值结果，均优于其它方法的分析结果。新生儿监护中当发生呼吸窘迫症状时，心跳可能仍然比较强劲，但血氧饱和度已明显变化。通过对新生儿血氧饱和度监测预测新生儿窒息有很高的敏感性，但特异性较低。Neonatal blood oxygen saturation monitoring can accurately, directly, real-time, and non-invasively reflect the neonatal oxygenation status and acid-base balance. Clinical research results show that blood oxygen saturation has a high correlation with the sensitivity and accuracy of predicting neonatal asphyxia. Neonatal blood oxygen saturation monitoring is a relatively reliable means of diagnosing respiratory distress during neonatal care, and many clinical studies have proved and supported the above conclusions. The sensitivity, specificity, positive predictive value and negative predictive value results of using neonatal blood oxygen saturation as the threshold for diagnosing neonatal abnormalities are all better than those of other methods. When respiratory distress symptoms occur in neonatal care, the heartbeat may still be relatively strong, but the oxygen saturation has changed significantly. Predicting neonatal asphyxia by monitoring neonatal oxygen saturation has high sensitivity, but low specificity.
血氧饱和度监测的基本原理：氧合红蛋白与还原血红蛋白在两个波长的光吸收作用不同；在两个波长的光吸收作用都有一个脉搏波部份。再根据波尔定理，溶质浓度与通过溶质的光传导强度有关，对于一个已知的溶质可以通过测量已知波长的入射光强度、透光强度和溶质容积来计算溶质浓度。The basic principle of blood oxygen saturation monitoring: oxyglobin and reduced hemoglobin have different light absorption at two wavelengths; the light absorption at both wavelengths has a pulse wave part. According to Bohr's theorem, the solute concentration is related to the light transmission intensity through the solute. For a known solute, the solute concentration can be calculated by measuring the incident light intensity, light transmission intensity and solute volume of known wavelengths.
血氧饱和度监测利用氧合血红蛋白和还原血红蛋白的分子吸收可见红光，波长为660nm，还原血红蛋白吸收红外线，波长为940nm，在搏动性组织两边放置光源和探头，随着动脉搏动吸收不同的光量，而没有搏动的皮肤和骨骼不起作用。光线信号转变为电信号经计算可显示血氧饱和度。Oxygenated hemoglobin and reduced hemoglobin molecules absorb visible red light with a wavelength of 660nm, and reduced hemoglobin absorbs infrared light with a wavelength of 940nm. Light sources and probes are placed on both sides of the pulsating tissue to absorb different amounts of light with the pulse of the artery. , and the non-pulsating skin and bones do not work. The light signal is converted into an electrical signal and can be calculated to display the blood oxygen saturation.
血氧饱和度信号的采集通常是通过固定指套或耳廓夹，采集手指、脚指、耳廓透光强度。为保证信号采集的可靠性和考虑摇动、脱落的的影响必须有一定的固定紧度，另外为保证连续监测还应具有透气性和舒适性，再则信号必须通过电线连接，必需注意由于导线拉扯产生的影响。The blood oxygen saturation signal is usually collected by fixing finger cots or auricle clips to collect the light transmission intensity of fingers, toes, and auricles. In order to ensure the reliability of signal acquisition and consider the influence of shaking and falling off, there must be a certain degree of fixed tightness. In addition, in order to ensure continuous monitoring, it should also have air permeability and comfort. In addition, the signal must be connected by wires. impact.
