Abstract
The multi-purpose non-toxic hemoglobin test device adopts single incandescent lamp light source and double light beam light path structure. One path is a sample test light path, and the other path is a reference light path. An interference filter is arranged on the sample testing light path, and two electric signals generated by the sample testing light path and the reference light path are processed by a post-operation circuit to obtain an electric signal which is linearly related to the concentration of the tested sample, namely the tested data.
The device adopts bromohexadecane trimethyl ammonia nontoxic testing agent as hemolytic agent, compared with virulent cyaniding high-iron method, it not only eliminates poison, but also has no pollution to environment, and greatly reduces cost.
Description
The utility model belongs to the multi-usage analytical instrument based on the mensuration haemoglobin in the clinical examination field.
Before the utility model, measuring haemoglobin is to adopt the high iron processes of cyaniding, with the toxic articles prussiate as hemolytic agent.Numerous and diverse to supervisory routines such as the buying of toxic articles, keeping, grantings, the reagent cost costliness is poisoned very big to operating personnel and environment simultaneously.
With the device of the most approaching mensuration haemoglobin of the utility model be the XF-1 type haemoglobin instrument that Nanjing semiconductor devices head factory is produced, as shown in Figure 1: form by two cold light sources 1, flow colorimetric pond 2, double detector 3, wedge 4 and shell 5.This device adopts cold light source, produces the monochromatic light of 540nm, and band is wide, monochromaticity is poor, wavelength accuracy is poor, veiling glare is big and can only do the unitem measurement of cyanmethemoglobin method.
Be to adopt nontoxic method to carry out the mensuration of haemoglobin in order to overcome above-mentioned shortcoming the purpose of this utility model, can improve wavelength accuracy simultaneously, reduce spectral bandwidth, improve monochromaticity reduction veiling glare, not only can survey haemoglobin, can also test other biochemical projects.
Detailed content of the present utility model is as shown in Figure 2: be by single incandescent light source 6, and window 7,14, interference filter 8, flow colorimetric pond 9, detector 10,13, wedge 12 and shell 11 are formed.
On the direction of propagation of the light of single incandescent light source 6, on the optical axis of sample test light path, be arranged in order window 7, centre wavelength is the interference filter 8 of 495-515nm.Flow colorimetric pond 9(or flow colorimetric pond 9, seeing through wavelength is the interference filter 8 of 495-515nm), detector 10 is arranged in order window 14 on the optical axis of reference path, and wedge 12 and detector 13, shell are 11.
Principle of work of the present utility model is: adopt single incandescent light source and twin-beam light channel structure.The light that single incandescent light source 6 is sent continuous radiation divides two-way to penetrate propagation.The window 7 of leading up to enters the sample test light path, and another road enters reference path by window 14.Enter the light of sample test light path, produce monochromatic light, projected after the absorption of sample on the sample photo-detector 10 by flow colorimetric pond 9 then, and convert the electric signal that becomes certain relation with absorption of sample to by detector 10 by interference filter 8; Enter the light of reference path, after wedge 12 weakens, project on the reference light detector 13, and convert to the light source width of cloth by detector 13 and to penetrate the electric signal that Strength Changes becomes certain relation.Two electric signal that sample test light path and reference path produce, after rearmounted computing circuit was handled, just obtaining one was the data of surveying with the linearly proportional electric signal of sample concentration.
Good effect of the present utility model is: adopt nontoxic method to carry out the mensuration of haemoglobin, not only eliminate to instrumentation personnel's murder by poisoning with to the pollution of environment, and adopt the bromohexadecane trimethyl to pacify nontoxic reagent as hemolytic agent, compared with the reagent that adopts the high iron processes of toxic articles cyaniding to be consumed, concerning every routine patient, the cost of bromohexadecane trimethyl ammonia only is 1/20 of the high iron processes cost of cyaniding.The device of the high iron processes of cyaniding is a single-use, can only survey haemoglobin, and the utility model device is multiduty, can not only survey haemoglobin, can also survey blood sugar, urea nitrogen, triglyceride, T-CHOL etc.The influence that this device energy is strong, monochromaticity good, veiling glare is low, stability is not subjected to light source fluctuation, the measuring accuracy height.
Description of drawings: Fig. 1 is the structural representation of prior art, and Fig. 2 is a structural representation of the present utility model, and Fig. 3 is the structural representation of most preferred embodiment.
Most preferred embodiment: for making this apparatus structure compactness, most preferred embodiment adopts structure shown in Figure 3.On the sample test light path, interference filter 8 is placed after the flow colorimetric pond 9, and make the rear hatch of flow colorimetric pond 9; On reference path, after single light source 6, put one 45 degree catoptrons 15, make reference path and sample test light path parallel, directive detector 13.
