The specific embodiment
The invention will be further described below in conjunction with concrete accompanying drawing.
Such as Fig. 1～shown in Figure 3, described photoelectric colorimetry blood loss metering pen comprises light source 1, light-dividing device 2, optical pickup apparatus 3, checkout gear 4, input/output unit 5, storage arithmetic unit 6, battery 7, metering pen shell 10 etc.
As shown in Figure 1, the present invention includes metering pen shell 10, light-dividing device 2 is installed on top at metering pen shell 10 head ends, optical pickup apparatus 3 is installed in bottom at metering pen shell 10 head ends, at metering pen shell 10 inner light source 1, checkout gear 4, input/output unit 5, storage arithmetic unit 6 and the batteries 7 installed, light source 1 is positioned at light-dividing device 2 rears; As shown in Figure 2, described light-dividing device 2 obtains the HONGGUANG that wavelength is 625nm with the light separation that light source 1 sends, optical pickup apparatus 3 receives the reflected light of test sample, the optical signal that checkout gear 4 receives optical pickup apparatus 3 converts the signal of telecommunication to and will transfer to input/output unit 5 and storage arithmetic unit 6 after the signal of telecommunication amplification, input/output unit 5 be connected arithmetic unit 6 and connect, the total courageous and upright liquid drainage amount data reduction that the signal of telecommunication after storage arithmetic unit 6 will amplify and input/output unit 5 are inputted becomes the blood loss amount and transfers to input/output unit 5; Described light source 1 adopts led light source, and light-dividing device 2 adopts monochromator, and optical pickup apparatus 3 adopts concave grating, and checkout gear 4 adopts photomultiplier, and input/output unit 5 is touching-type monitor.
As shown in Figure 3, the matching used drainage bottle of described photoelectric colorimetry blood loss metering pen comprises drainage bottle bottle 20, this drainage bottle bottle 20 is rectangular-shaped, and a sidewall of drainage bottle bottle 20 is can catoptrical minute surface, and the sidewall of a side relative to this minute surface is clear glass.
Operation principle of the present invention: in the art bloody fluid is incorporated in the drainage bottle by the method that attracts as far as possible, use again the photoelectric colorimetry principle to measure red blood cell mass in the drainage-fluid, then accurate Calculation amount of bleeding very intuitively accomplishes in time to correct the Hypovolemia state.The operation principle of photoelectric colorimetry principle is similar with general spectrophotometer, bloody drainage in the middle of performing the operation is carried out the photoelectricity turbidimetric assay, because blood is behind normal saline dilution, erythrocytic quantity is proportional within the specific limits in the turbidity that presents and the courageous and upright liquid, when using the monochromatic light transmission operative drainage bottle of specific wavelength, adopt first distilled water to transfer " 0 ", carry out again photoelectric colorimetry, read optical density, according to RBC number-optical density standard curve, can obtain erythrocytic quantity in every milliliter of courageous and upright liquid, be multiplied by the bloody fluid total amount and namely obtain total erythrocyte amount lost, according to the corresponding relation of the different erythrocyte number of men and women with blood volume, calculate total amount of bleeding again.Namely, first the wherein one side of drainage bottle being carried out mirror-polishing processes, when the monochromatic light of specific band penetrates courageous and upright liquid in the drainage bottle and arrives on the offside minute surface, on the light beam bounce-back light echo receiving element, by the final readable bright dipping density data of opto-electronic conversion, because the optical density data with the proportional relation of erythrocyte number in the courageous and upright liquid, can obtain the erythrocytic total amount of losing by converting.
Work process of the present invention: as shown in Figure 3, the one side of the head end of photoelectric colorimetry blood loss metering pen being close to drainage bottle, the light that light source sends is isolated monochromatic HONGGUANG by light-dividing device, this monochromatic HONGGUANG just in time low-angle shines on the opposite side minute surface of drainage bottle, and reflected light receiving system, after carrying out opto-electronic conversion and the signal of telecommunication amplified by checkout gear, record and show by touching-type monitor, touching-type monitor is the display light density data directly, be converted into every milliliter of erythrocyte number by RBC number-optical density standard curve function again, input in drainage bottle that detection time point read bloody fluid total amount at touching-type monitor this moment, erythrocytic quantity is multiplied by the bloody fluid total amount and namely obtains total erythrocyte amount lost, then is converted into blood volume by the different erythrocyte number of men and women with the blood volume corresponding relation.
Before using, to finish first the making of RBC number-optical density standard curve, its manufacturing process is as follows: at first make simple and easy photoelectric colorimetry blood loss metering pen (without the storage arithmetic unit, only can read the optical density data) according to the similar technology index; By the same material of operative drainage bottle, same wall thickness design large size test tube, test tube is rectangular build, and wherein one side is used same mirror process; Choose each 15 conduct blood samplings of healthy young and middle-aged men and women volunteer source, getting 5 large size test tubes is numbered, in each pipe, add successively 1.5% sodium chloride solution 5,8,10,16,20 milliliters, accurately draw volunteer's peripheral vein anticoagulation 20 microlitres with hemoglobin straw, put upside down mixing after slowly adding test tube, (add a blood with every milliliter of RBC number in the microscopic counting pipe at once, counting one pipe, because erythrocyte reduces along with time lengthening in hypertonic saline), measuring optical density by effective photoelectric colorimetry blood loss metering pen simultaneously (finishes to colorimetric from the dilution blood sample, time is not above 60 minutes), use before this distilled water to transfer " 0 " (its optical density is consistent with 1.5% sodium chloride solution), then take each pipe institute photometry density as vertical coordinate, each pipe counting RBC number is abscissa, plots standard curve.At last, the erythrocyte number that phototurbidometry and microscopic counting are recorded compares, and understanding has no difference of science of statistics, and same volunteer's blood sample is carried out the retest of different times, and whether the repeated accuracy of understanding the method is good.
