Description

A kind of bilirubin concentration detection system

Technical field

The utility model relates to a kind of Systems for optical inspection, especially a kind of bilirubin concentration detection system.

Background technique

Jaundice is that newborn's very common clinical symptoms of the latter of being born pay close attention to its blood gallbladder for newborn Lycopene concentration (jaundice index) has very important significance, and to find and distinguish the property of jaundice early, prevents pathologic Jaundice further develops, and causes nuclear icterus even dead.Currently, being usually taken after thorn foot in terms of detecting bilirubin concentration With method for measuring in the blood sample of acquirement, this can bring pain to newborn, while it is big to detect inconvenient and detection time General to need one hour, the delay time at stop is long.

Also there is the device of infrared spectrometry bilirubin concentration at present, but the range measured is deviated, the gallbladder taken Red pigment absorption peak is also each different, but is substantially the bilirubin concentration of blood in directly detection blood vessel, and the numerical value of detection is not It is enough accurate, it is deviated, causes to influence to judge.

Utility model content

To solve the above problems, the purpose of this utility model is to provide a kind of bilirubin concentration detection system, structure letter It is single, it can accurately measure the bilirubin concentration in newborn blood.

The technical solution adopted by the utility model to solve the problem is as follows:

A kind of bilirubin concentration detection system, which is characterized in that including light source, be used for transmission light Y type probe, be used for It obtains the detection body reflectance spectrum figure that wave-length coverage is 430 to 600nm and converts optical signals to the spectrum acquisition mould of electric signal Block and for detection body reflectance spectrum figure carry out detect and the detection mould of bilirubin concentration is obtained by the absorption peak of 455nm Block, the spectrum obtain module and connect with detection module；The Y type probe includes the first bifurcation mouth, the second bifurcation mouth and probe End, the light source are placed in the first bifurcation mouth of Y type probe, and the spectrum obtains the second bifurcation mouth that module is connected to Y type probe, The sound end of the Y type probe is placed on detection body.

Preferably, the light source is halogen lamp of the wave-length coverage between 400-2500nm.

Preferably, the Y type probe is made of optical fiber.

Preferably, it is spectrometer that the spectrum, which obtains module,.

The beneficial effects of the utility model are: a kind of bilirubin concentration detection system that the utility model uses, structure letter It is single, easy to use, intelligent operation；The wavelength of blood can be obtained by irradiating to the tissues surrounding vascular in newborn skin Reflectance spectrum figure of the range between 430-600nm, and detect and obtain the bilirubin absorption peak of 455nm；Without shouting pain newborn Blood sample is obtained, it is convenient and efficient accurate.

Detailed description of the invention

The utility model is described in further detail with example with reference to the accompanying drawing.

Fig. 1 is the structure chart of the utility model bilirubin concentration detection system.

In Fig. 1,2 pop one's head in for Y type, and 21 be the first bifurcation mouth, and 22 be the second bifurcation mouth, and 23 be sound end.

Specific embodiment

Referring to Fig.1, the utility model discloses a kind of bilirubin concentration detection system, including light source 1, it is used for transmission light Y type probe 2, for obtain wave-length coverage be 430 to 600nm detection body reflectance spectrum figure and convert optical signals to telecommunications Number spectrum obtain module 3 and for detection body reflectance spectrum figure carry out detect and gallbladder is obtained by the absorption peak of 455nm The detection module 4 of lycopene concentration, the spectrum obtain module 3 and connect with detection module 4；The Y type probe 2 includes the first fork The 21, second bifurcation mouth 22 of mouth and sound end 23, the light source 1 are placed in the first bifurcation mouth 21 of Y type probe 2, and the spectrum obtains Module 3 is connected to the second bifurcation mouth 22 of Y type probe 2, and the sound end 23 of the Y type probe 2 is placed on detection body.

What traditional bilirubin spectroscopic assay obtained is the bilirubin concentration of blood in blood vessel, is to influence result accuracy rate One key factor；The bilirubin concentration detection system after testing system 4 obtain be tissues surrounding vascular bilirubin it is dense Degree.Optical signal is issued from light source 1, is injected from the first bifurcation mouth 21 of Y type probe 2, by the channel of Y type probe 2, is visited in Y type First 2 sound end 23 projects, and projects on detection body i.e. bilirubin concentration detection zone；Optical signal is reflected the second of Y type probe 2 Bifurcation mouth 22 enters spectrum and obtains module 3, forms wave-length coverage and is 430 to 600nm detection body reflectance spectrum figure, and light is believed Number being converted into electric signal is transported in detection module 4；Detection module 4 obtains module 3 from spectrum and receives detection body reflectance spectrum Figure, and absorption peak of the bilirubin concentration at 455nm is obtained from the spectrogram.Can blood directly be observed from detection system Bilirubin concentration absorption peak at the detection body reflectance spectrum figure of the 430 to 600nm of liquid and directly reading 455nm, it is convenient fast It is prompt accurate.

Preferably, the light source 1 is halogen lamp of the wave-length coverage between 400-2500nm.

Preferably, the Y type probe 2 is made of optical fiber.

Preferably, it is spectrometer that the spectrum, which obtains module 3,.

In addition, bilirubin concentration detection system further includes bracket, the sound end 23 of Y type probe 2 is fixed on bracket, detects Body is put in 23 lower section of sound end of Y type probe 2；Light is projected from sound end 23, is irradiated on detection body, bracket makes sound end 23 Stablize, prevents light from rocking, influence to measure.

The above, the only preferred embodiment of the utility model, the utility model are not limited to above-mentioned implementation Mode, as long as its technical effect for reaching the utility model with identical means, all should belong to the protection scope of the utility model.
