Description
Technical field
This utility model relates to the pulse blood oxygen instrument of a kind of HONGGUANG and infrared light one.
Background technology
Pulse blood oxygen instrument is a kind of no wound, and the medical instrument of continuously monitoring human body arterial oxygen saturation has been widely used in places such as hospital, community, clinic, family.And then pulse blood oxygen instrument accuracy, concordance, cost there has been higher requirement.
The principle of pulse blood oxygen instrument is to be foundation according to reduced hemoglobin (R Hb), HbO2 Oxyhemoglobin (O2 Hb) absorption Spectrum characteristic in HONGGUANG and nearly HONGGUANG zone, and utilization Lambert Beer law is set up the date processing empirical equation.Obtain measuring-signal with light (HONGGUANG of 660nm and the infrared light of 940nm) the irradiation human body nail tip of two bundle different wave lengths by light-sensitive element, institute's signal that obtains shows measured result by display after amplifier, AD converter and microprocessor processes.
At present, the pulse blood oxygen instrument on the domestic and international market adopts HONGGUANG, the discrete analogue technique of infraluminescence pipe mostly.The shortcoming of this method has: the one, and discrete luminous tube has increased the measurement error that causes because of the light intensity deviation, the concordance variation that makes batch process; The 2nd, the analog circuit more complicated has been used amplifier and AD converter, if use high-precision device will inevitably increase cost, uses the device of low precision can increase measurement error.
Summary of the invention
The purpose of this utility model just provides a kind of pulse blood oxygen instrument of HONGGUANG infrared light one,, circuit complexity poor with the concordance that solves the batch process that prior art exists and the high problem of cost.
The technical scheme that its technical problem that solves this utility model adopts is: comprise battery, manostat, light-to-frequency converter, microprocessor, display and emission driver, battery is connected with above-mentioned miscellaneous part by manostat, microprocessor connects with light-to-frequency converter with the input of display, luminous tube driver respectively by the I/O mouth, it is characterized in that: be connected with the HONGGUANG infrared tube that is become one by red light-emitting pipe and infraluminescence pipe in described luminous tube output end of driver.
Described manostat comprises first manostat and second manostat, the input of this first manostat and second manostat is connected with described battery, the outfan of this first manostat is connected with light-to-frequency converter, and the outfan of this second manostat is connected with miscellaneous part except this light-to-frequency converter.
Luminous component of the present utility model adopts red light-emitting pipe, the integrated HONGGUANG infrared tube of infraluminescence pipe, and signals collecting has partly been used light-to-frequency converter spare, light intensity signal is directly changed into be digital signal.Through test determination, this scheme reduces the measurement error that causes because of discrete light-emitting pipe light intensity deviation, increase the concordance of producing in batches, avoided the measurement error that causes because of precision, the temperature of amplifier and AD converter problem such as float simultaneously, can effectively improve the certainty of measurement of pulse blood oxygen instrument, reduce cost.

Fig. 1 is a formation block diagram of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples this utility model is described in further detail:
Referring to Fig. 1, this utility model comprises battery 1, first manostat 2 and second manostat 3, light-to-frequency converter 4, microprocessor 6, display 7, HONGGUANG infrared tube 8 and emission driver 9, and microprocessor 6 is connected 4 with the input of display 7, luminous tube driver 9 respectively by the I/O mouth and connects with light-to-frequency converter.It is characterized in that: the outfan in described luminous tube driver 9 is connected with the HONGGUANG infrared tube 8 that is become one by red light-emitting pipe and infraluminescence pipe.
Battery 1 passes through manostat 2 and manostat 3 voltage stabilizings respectively, and the power supply of light-to-frequency converter 4 is provided separately by manostat 2, and the power supply of miscellaneous part is by manostat 3 power supplies.
When measuring, tissue 5 is located between light-to-frequency converter 4 and the HONGGUANG infrared tube 8, periodically export two pulse signals chronologically at microprocessor 6, drive HONGGUANG infrared tube 8 successively by emission driver 9, the light pulse of sending is after tissue 5 decay, directly optical signal transmissive is changed into digital pulse signal by light-to-frequency converter 4, promptly with the proportional pulse signal of transmitted light intensity, and be sent to microprocessor 6, count and timing by 6 pairs of these pulse signals of microprocessor, and expand calculating accordingly, carry out corresponding digital signal afterwards and calculate, obtain blood oxygen saturation and heart rate value, demonstrate numeral by control display 7.
This scheme reduces the measurement error that causes because of discrete light-emitting pipe light intensity deviation, increase the concordance of producing in batches, adopt simultaneously light intensity signal is directly changed into and be digital signal processes, avoided the measurement error that causes because of precision, the temperature of amplifier and AD converter problem such as float, can effectively improve the certainty of measurement of pulse blood oxygen instrument, reduce cost.
