Abstract
The utility model discloses an oxygen saturation detecting instrument which comprises an oxygen saturation data collecting device and a data processing device. The oxygen saturation detecting instrument further comprises a skin information collecting device, the skin information collecting device is in communication connection with the data processing device and transmits collected skin color data to the data processing device, and the data processing device filters out skin color information in data transmitted by the oxygen saturation data collecting device according to the skin color data. Through the adoption of the technical scheme, the oxygen saturation detecting device can eliminate influences on the absorption and reflection of red light and infrared light by dark skin colors, and improve oxygen saturation detecting precision.
Description
Technical field
This utility model relates to medical apparatus and instruments field, relates in particular to a kind of blood oxygen saturation detector.
Background technology
In prior art, the measuring method of blood oxygen saturation is to adopt finger cot type photoelectric sensor, when measurement, by sensor sleeve on finger, utilize the transparent vessel of finger as splendid attire hemoglobin, use the HONGGUANG of wavelength 660nm and the near infrared light of 940nm as injecting light source, measure the light conduction intensity by tissue bed, calculate hemoglobin concentration and blood oxygen saturation, instrument can show human body blood oxygen saturation.
But in above-mentioned measuring method, because user skin surface colour darkness is inconsistent, skin weight is crossed deeply the performance of the absorption that causes skin to spectrum and reflection different with the skin of the normal colour of skin, will affect tester's the blood oxygen saturation detected value of dark skin thus.
Therefore, need a kind of novel blood oxygen saturation checkout equipment, the absorption to HONGGUANG and infrared light of the dark colour of skin, reflections affect can be eliminated, improve blood oxygen saturation accuracy of detection.
Utility model content
The purpose of this utility model is to provide a kind of blood oxygen saturation detector, and the value of the light that skin is absorbed, reflected is carried out color compensating, improves blood oxygen saturation accuracy of detection.
The utility model discloses a kind of blood oxygen saturation detector, comprise blood oxygen saturation data acquisition unit and data processing equipment, described blood oxygen saturation detector also comprises skin information collecting device, be connected with described data processing equipment communication, the skin color data of collection are sent to described data processing equipment; Skin color information filtering in the data that described data processing equipment is sent described blood oxygen saturation data acquisition unit according to described skin color data.
Preferably, described skin information collecting device comprises shading device, light source and RGB color sensor, and described shading device is coated on outside described blood oxygen saturation data acquisition unit, and the light in blood oxygen saturation data acquisition unit is completely cut off with outside; Described light source is located in described blood oxygen saturation data acquisition unit, and by the illumination of sending to skin; Described RGB color sensor detection of skin color and by described skin color transfer of data to described data processing equipment.
Preferably, described shading device is black shade.
Preferably, described light source is LED lamp.
Preferably, described RGB color sensor comprises three optical filters, is respectively HONGGUANG optical filter, green glow optical filter and blue filter.
Adopt after technique scheme, in skin absorption, reflectance spectrum, because the impact of the colour of skin itself will be filtered off, blood oxygen saturation detector detected value is more accurate.
Brief description of the drawings
Fig. 1 is the system structure schematic diagram of this utility model blood oxygen saturation detector.
Detailed description of the invention
Further set forth advantage of the present utility model below in conjunction with accompanying drawing and specific embodiment.
Consulting Fig. 1, is the system structure schematic diagram of this utility model blood oxygen saturation detector.Blood oxygen saturation detector comprises blood oxygen saturation data acquisition unit and data processing equipment, blood oxygen saturation data acquisition unit is connected with data processing equipment by DCB, and transfer of data to the data processing equipment of the skin absorption, reflect red and the infrared light that detect is processed.Blood oxygen saturation detector also comprises skin information collecting device, be connected with described data processing equipment communication, the skin color data of collection are sent to described data processing equipment, according to described skin color data, the skin color information filtering in the data that described data processing equipment is sent described blood oxygen saturation data acquisition unit.Particularly, skin information collecting device comprises RGB color sensor, shading device and light source.After the color of RGB sensor detection of skin or weight, above-mentioned information is sent to data processing equipment, RGB color sensor preferably has three optical filters, be respectively HONGGUANG optical filter, green glow optical filter and blue filter, leach the light of other all colours except primary colors red is turquoise, only detect trichromatic colouring information in tester's skin, saved in trace routine the program without the detection of using up.After above-mentioned information, convert optical signal to analog or digital signal and send to data processing equipment and process.Light source in blood oxygen saturation is located in blood oxygen saturation data acquisition unit, concurrent bright dipping is shone to skin, for the light of the offer help reflection of RGB color sensor detection of skin, absorption spectrum, the shading device of blood sample saturation detector is coated on outside blood oxygen saturation data acquisition unit, with outside isolated, avoid exterior light to be irradiated into the accuracy that affects current detection data after blood oxygen saturation data acquisition unit the light in blood oxygen saturation data acquisition unit.
In one preferred embodiment, shading device is black shade, and black shade shaded effect the best, to the isolated better effects if of light.
In another preferred embodiment, light source is LED lamp, and the light sending is white in color, and the red, green, blue after being filtered by optical filter is purer, and the colouring information of collecting is more accurate.
Data processing equipment receives after the colouring information that RGB color sensor sends, error blood oxygen saturation being caused according to different colours, in the HONGGUANG that blood oxygen saturation data acquisition unit is sent and the data of infrared light, the part of skin color impact leaches, to reach the process of color compensating, revise the data of HONGGUANG and infrared light.
Adopt after technique scheme, in skin absorption, reflectance spectrum, because the impact of the colour of skin itself will be filtered off, blood oxygen saturation detector detected value is more accurate.
Should be noted that, embodiment of the present utility model has preferably implementation, and not this utility model is done to any type of restriction, any person skilled in art of being familiar with may utilize the technology contents of above-mentioned announcement to change or be modified to the effective embodiment being equal to, in every case do not depart from the content of technical solutions of the utility model, any amendment or equivalent variations and the modification above embodiment done according to technical spirit of the present utility model, all still belong in the scope of technical solutions of the utility model.
