Abstract
The invention discloses a light path system of a vein projector and a vein projector. The light path system comprises multiple infrared LEDs (5), a CCD camera (6), a projector body (7) and a spectroscope (8), wherein incident light of the CCD camera (6) is perpendicular to emergent light of the projector body (7); the spectroscope (8) is located at the intersecting position of an incident light path and an emergent light path and forms a 45-degree angle with the incident light path and the emergent light path, band-pass filtering is adopted in the spectroscope (8), and the spectroscope (8) is selectively pervious to a visible light wave band and reflects near infrared light; the infrared LEDs (5) emit infrared band light waves to the surface of the skin, the CCD camera (6) shoots the reflected infrared light, the infrared light reflected from the surface of the skin is reflected by the spectroscope (8) and incident into the CCD camera (6) after the direction of the infrared light is changed by 90 degrees, visible light emitted by the projector body (7) passes through the spectroscope (8) and is directly transmitted to the surface of the skin to conduct in-situ projection, and the visible light emitted by the projector body (7) and the infrared light taken by the CCD camera (6) are located on the same light path outside the vein projector. The light path system can be applied to the field of medical apparatus and instruments.
Description
Technical field
The present invention relates to a kind of light path system of venous projecting apparatus; In addition, the invention still further relates to oneVenous projecting apparatus.
Background technology
Before more than 100 year, the mankind's medical advance to start to use vessel puncture draw blood and input blood,Physiological saline and so on liquid, but implement the key of this medical technology, be exactly first to manage to find human bodyBlood vessel, could play pin puncture vessel to carry out follow-up treatment. When puncture to as if when children, because blood vesselMore carefully be difficult for seeing clearly, puncture to as if when the elderly of prolonged illness because repeatedly puncture or site of puncture is limited,The reasons such as blood vessel is slim and frahile are also difficult to find suitable puncture vessel. How to look at patient rapidly and accuratelyJust seem extremely important to blood vessel.
At present, the method for clinical used localization of blood vessel mainly contains two kinds: visual method---look with nakedFind and localization of blood vessel, this method is only suitable for venous locations and shows shallow and outstanding patient, for skinThe state of vessel size, bending and the bifurcated of undertissue, in fact cannot ensure very clear; Digital palpation for examination of trauma---find and localization of blood vessel with the sensation touching, this method is that medical personnel rely on experience for many years,Touching the sensation of skin, tell blood vessel different from the matter of surrounding tissue, thereby determine blood vesselPosition and the depth. At present, under dorsal cutaneous, venipuncture injection feeding is clinical treatment means the most widely,Carrying out venipuncture injection operation and carry out puncture procedure nurse for the slim and frahile patient of some venae subcutaneaesTime, failed ratio is high, and therefore child patient can cry and scream especially, and nurse is also often subject to families of patientsBlame for even and reprimand, thought pressure is very big.
In sum, venipuncture is the medical procedure of medically commonly using, but the mortality of having an acupuncture treatment is higher,Especially concerning the unconspicuous patients of vein such as newborn children and obese people, mortality is higher, thereforeStrengthen intravenous contrast and can effectively improve acupuncture treatment success rate, not only alleviated medical personnel's workAmount, and reduced the misery of bringing to patient because of puncture failure, there is very important practical significance.
The principle that vein develops is because the hemoglobin on red blood cell in venous blood has after losing oxygenOne specific character, can absorbing wavelength scope at the near infrared light of 700～1000nm, and musculature andBone has good transmittance to the light wave of this wavelength, therefore uses the near-infrared light source in this wave-length coverageWhen the transmission of opponent's fingering row, due to finger vena blood vessel and the difference of musculature to infrared Absorption around,Can carry out the radiography to superficial vein blood vessel, realize vein and differentiate.
Vein display device has superior technical advantage, can be on the original workmanship of medical personnel basisOn greatly improve work quality, reduce sufferer misery, improve medical services image. In the last few years, veinShadow casting technique's develop rapidly, performance constantly promotes. Vein display device has passed through multiple developing stage, orderBefore still develop among.
The vein display device of first stage is red or orange high-powered LED lamp, and this generation product is commonSelect red LED or 1～3W, the orange LED of wavelength 615nm of 1～3W, wavelength 630nm,The structure of the LED lamp in this generation product is often designed to be held in the hand, patient wants to strengthen the back of the handVein display effect, just must grip LED light rod, by venous blood and perienchyma to thisSpecific wavelength absorptivity difference is observed vein at the back of the hand, and then guided puncture. This generation product just likeLower several shortcomings: thereby 1, infant cannot coordinate and cannot use; 2, children are reluctant to coordinate; 3, becomePeople's palm penetrates weak effect; 4, grasp LED light rod slightly long LED lamp of time and just can produce high heat; 5,Under bright light environments, result of use is poor.
The vein display device of second stage is vein visualizer, and this generation product uses wavelength 850nm'sInfrared light is as light source, for strengthening the general mode that adopts upper and lower light source to be used in conjunction of penetration power. 850nm is infraredLight penetration power is good compared with 630nm ruddiness, can effectively penetrate adult's palm etc. thicker while adopting lower illuminating sourceTissue. But 850nm infrared light cannot detect by an unaided eye, so need use sense infrared camera to carry outImaging. After imaging, through simple image processing, such as carry out contrast, brightness, gamma curve,Edge enhancing etc. process after by analog signal outputs such as AV to display screen. This generation product has as followsSeveral shortcomings: need to grasp infrared lower illuminator when 1, patient carries out hand back vein puncture, exist to intersect and feelDye or patient be reluctant coordinate problem; 2, doctor needs view screen on one side to puncture on one side, uses notConvenient; 3, resolution ratio is limited.
The vein display device of phase III is development vein projection out on the basis of vein visualizerInstrument, is transferred on projecting apparatus by AV signal after sense infrared camera imaging processing, by specialLight path design projects on skin vein image original position, and it has solved doctor needs view screen one on one sideLimit is the difficult problem that patient has an acupuncture treatment. But because of the shortcomings such as its intrinsic defect causes resolution ratio low, and frame frequency is slow, shadowRing the large-scale promotion of this series products. Current vein projection products generally adopts analog signal input, LcosRay machine projection output, although can significantly reduce costs, since image algorithm weakness, display effectNot fully up to expectations. Adopt analog video input that resolution ratio and frame frequency are declined, this can cause vein edgeCoarse, unsmooth, the phenomenon such as when mobile time delay is serious.
