Description
Technical field
The utility model relates to jaundice detection technique field, especially a kind of adult jaundice measurement device.
Background technique
Jaundice is common sympton and sign, is to cause bilirubin concentration in serum due to bilirubin metabolism obstacle
Caused by raising.Clinical signs are that sclera, mucous membrane, skin and its hetero-organization are dyed to yellow.Because sclera contains more elasticity
Scleroprotein has stronger affinity with bilirubin, thus Patients with Jaundice icteric sclera often prior to mucous membrane, skin and be noticeable first.
When serum total bilirubin is in 17.1~34.2 μm of ol/L, and naked eyes do not see jaundice, claim jaundice occult or subclinical jaundice；When
When serum total bilirubin concentration is more than 34.2 μm of ol/L, jaundice, also referred to as clinical jaundice can be clinically found.
Icterus neonatorum is neonatal period common disease, is especially more common in premature, refers to that newborn mucous membrane occurs, consolidates
The clinical symptoms of film, xanthochromia, pathogenic factor be mainly neonatal blood-brain barrier develop at birth it is incomplete, such as
Very big influence can be brought to neonatal intellectual development if fruit icterus index is excessively high and treatment is not prompt enough, serious infant can
Lead to bilirubin encephalopathy, to cause irreversible damage to infant brain, consequence is serious.Therefore, to the pre- of icterus neonatorum
Anti- and treatment should give enough attention.Blue-ray radiation therapy is that the treatment Jaundice in Premature Infants clinically approved most has all the time
One of cure method of effect.
Blue-light treatment (light of 420~470nm of wavelength irradiates), is the primary treatment method of clinically icterus neonatorum, energy
So that the intracorporal indirect bilirubin of infant is changed into nontoxic soluble derivative, contains to reduce the intracorporal serum bilirubin of infant
Amount, prevents the generation of bilirubin encephalopathy.Blue-ray radiation therapy method is clinically frequently with two kinds at present: interval blue light illumination with hold
Continuous blue light illumination mode.Existing meter for newborns,jaundice be using blue light wave (450mm) and green light wave (550nm) it
Between light wave it is poor, to measure the concentration for being deposited in bilirubin in newborn baby's skin histology.There are two light for jaundice analyzer probe
Wave makes the concentration that can determine the bilirubin in newborn skin tissue under the influence of melanin and skin maturation phase in this way
Minimum value.It is not attainable that this point, which is traditional approach,.After probe is placed in front of baby forehead or breastbone position and startup power supply,
The light that xenon light pipe issues directs into skin surface through glass fibre, and direct projection is subcutaneous.Light wave on the skin disperse repeatedly with
It absorbs, is eventually returned to glass fibre.It is dispersed in back to the light part of glass fibre through fiber inner core (short in superficial skin tissue
Light wave), the outer core (long light wave) of another part light is deep into skin histology, and is reached in skin histology, and reach corresponding photoelectricity
Diode.By calculating the difference of optical density, common light wave will be deducted between epidermis and corium.What is obtained is only skin group
The poor optical density of two range of wavelengths in knitting.The differential disply of light wave density goes out the serum bilirubin being connected, the reading on display
For serum bilirubin level value.
And for adult Patients with Jaundice, since adult skin is thicker, the long glistening light of waves can not all be deep into skin histology
It is interior, it is incomplete to the absorption of light, to influence the accuracy of measurement result.Therefore, the detection of adult jaundice, hospital generally pass through
Inspection to serum, urine, liver function detects the content of its mesobilirubin.But this detection method due to need take a blood sample,
Human body is damaged larger.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of adult noninvasive jaundice analyzers.
The technical scheme adopted by the utility model is adult jaundice measurement device, including analyzer ontology, setting are being surveyed
Determine the intrinsic light source of instrument, test probe, control unit, further includes the display being arranged on analyzer body outer surface, light
Source, test probe, display parallel connection are provided with contact canthus on the control unit, in one end of the test probe of analyzer ontology
The keratoscope of film, keratoscope directly detect sclera, keep testing result more accurate, make detection light can be more after keratoscope reflects
Detection sclera on a large scale keeps detection more accurate, and keratoscope outer surface is provided with light shield layer, and light shield layer prevents light from leaking to inspection
Survey personnel damage.
Further, the lesser face connecting test probe of cornea curvature radius, guarantees the dioptric of adjustable eyes
Degree.
Further, light shield layer is made of reflective resin.
(1) keratoscope of contact cornea is provided in one end of the test probe of analyzer ontology, keratoscope is directly examined
Survey sclera, keep testing result more accurate, make detection light after keratoscope reflects can larger range of detection sclera, make to detect
It is more accurate and easy to operate, it is at low cost.
(2) keratoscope outer surface is provided with light shield layer, and light shield layer prevents from light from leaking damaging testing staff.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
In the figure, it is marked as 1- analyzer ontology, 2- test probe, 3- display, 4- keratoscope, 5- light shield layer.
Specific embodiment
The present invention will be further described with reference to the accompanying drawing.
As shown in Figure 1, the adult jaundice measurement device of the utility model, including analyzer ontology 1, it is arranged in analyzer sheet
Light source, test probe 2, control unit in body 1, it further includes setting that light source, which includes shortwave radiant and long wave radiant in parallel,
The display 3 on 1 outer surface of analyzer ontology is set, light source, test probe 2, display 3 are in parallel on the control unit, are surveying
The one end for determining the test probe 2 of instrument ontology 1 is provided with the keratoscope 4 of contact cornea, by 4 radius of curvature of keratoscope lesser one
Face connecting test probe 2, the cross-sectional area of keratoscope 4 should enable keratoscope 4 cover eyes, the setting of 4 outer surface of keratoscope
There is light shield layer 5, light shield layer 5 is made of reflective resin, can be in manufactured shading layer surface in order to further strengthen shaded effect
Be coated with one layer of graphite, reflective resin can choose PMMA, PHEMA, PMMA and NVP copolymer, HEMA and MAA copolymer,
One of IPN, polyurethane hydrogel, silicone-hydrogel or fluoropolymer can specifically be surveyed in the jaundice described in background technique
Determine to add keratoscope, light shield layer on the test probe of instrument, shortwave radiant and long wave radiant are green light wave respectively
(550nm), blue light wave (450mm).
When specific measurement, keratoscope 4 is contacted the eyes of patient by (a) first；(b) power supply, long wave radiant and short are opened
Light wave light source is irradiated on cornea through keratoscope 4, and short wavelength light is dispersed in superficial keratectomy tissue, and long light wave is deep into cornea group
In knitting, light source can more broadly be irradiated to cornea after keratoscope 4；(c) corresponding acquisition module receives optical signal
After feed back to control unit, the processing module of control unit converts thereof into electric signal；(d) processing module of control unit according to
The poor optical density calculation processing of the short wavelength light, the long glistening light of waves that detect obtains bilirubin concentration information and is shown by display 3.
