Abstract
The utility model relates to a vein seeking device and belongs to medical instruments. The vein seeking device comprises a 785nm near-infrared light laser generator, a 642nm visible light laser generator and a polarization splitting prism. The 785nm near-infrared light laser generator is vertical to the 642nm visible light laser generator. The polarization splitting prism is used for respectively transmitting and reflecting the generated near-infrared laser and the visible laser and combining near-infrared laser and visible laser into the same light beam. After the light beam irradiates the surface of a detected area through a light path collimating lens, a convergent lens, an X-axis reflecting mirror, a Y reflecting mirror and an optical level lens assembly, generated reflected lights are respectively received by a near-infrared light sensor group and a laser distance measuring sensor. The vein seeking device has the advantages of being novel in structure, capable of displaying vein blood vessels in an all-around mode, and flexible in equipment utilization.
Description
Technical field
This utility model belongs to Medical Instruments.
Background technology
The body surface intravenous injection is the very basic very important operation again of medical field, and the definition that vein blood vessel shows under the skin determines the complexity of intravenous injection puncture.At present, develop method and the device of multiple vein blood vessel development both at home and abroad and applied for patent, for example (1) is used for method and the supersonic imaging apparatus (patent No.: 200910225863.8) utilize ultra sonic imaging principle identification arteriovenous of identification arterial-venous.(2) the hand held intravenous injection development transilluminator (patent No.: 20102000357307) see through the back of the hand with staggered use of the light source of 590 ~ 660nm different wave length, show the hand back vein blood vessel.(3) a kind of multispectral three-dimensional vein image display device (patent No.: 201210313052.5), this equipment be by multispectral infrared light supply, multichannel video camera, visible light by infrared permeation filter plate and projection display apparatus, the camera acquisition skin image is projected to as calculated the zone of corresponding skin after the cell processing.(4) the Vein scanner(patent No. of the U.S.: 20110125028) place fixing height and angle based on equipment, the mode that near-infrared laser and red laser scan shows vein blood vessel.Above typical patent to enumerate the main technology of searching of having introduced existing domestic and international vein blood vessel mainly be laser scan type, transmission-type, ultra sonic imaging, based on the display instrument video picture of infrared light reflection formula with based on the reflective projection video picture of infrared light reflection formula.Yet, these technology all are the vein blood vessel video pictures at skin surface, and the vein blood vessel that the equipment that has can only show the specific region is the back of the hand for example, the placement location of equipment requires very high, the development that need just can realize clear vein blood vessel according to fixing height and angle has a lot of limitation.
Summary of the invention
This utility model provides a kind of vein to search device, to solve present vein blood vessel unsharp problem of developing.
The technical scheme that this utility model is taked is: comprise into 785nm near infrared light laser generator and 642nm visible light laser generator and polarization splitting prism that an angle of 90 degrees is arranged, behind the near-infrared laser and visible laser difference transmission and reflection that described polarization splitting prism is used for producing, make near-infrared laser and visible laser synthesize same light beam, the beam path alignment lens of this light beam through arranging successively, collecting lens, the X-axis reflecting mirror, the Y-axis reflecting mirror, after the optical lever battery of lens shone tested area surfaces, the reflected light of formation was received by near infrared light sensor groups and laser range sensor respectively.
The near infrared light sensor groups is in same plane by two groups and mutually perpendicular near infrared light sensor is formed.
This utility model advantage is novel structure, the omnibearing demonstration vein blood vessel of energy, and equipment uses flexibly.

The specific embodiment
Comprise into 785nm near infrared light laser generator 1 and 642nm visible light laser generator 2 and polarization splitting prism 3 that an angle of 90 degrees is arranged, behind the near-infrared laser and visible laser difference transmission and reflection that described polarization splitting prism is used for producing, make near-infrared laser and visible laser synthesize same light beam, the beam path alignment lens 4 of this light beam through arranging successively, collecting lens 5, X-axis reflecting mirror 6, Y-axis reflecting mirror 7, after optical lever battery of lens 8 shone tested area surfaces, the reflected light of formation was received by near infrared light sensor groups 9 and laser range sensor 10 respectively.
The near infrared light sensor groups is in same plane by two groups and mutually perpendicular near infrared light sensor is formed.
Behind the laser beam process beam path alignment lens 4 that near-infrared laser and visible laser synthesize, collecting lens 5, X-axis reflecting mirror 6, the Y-axis reflecting mirror 7, by 8 focusing of optical lever battery of lens, two initial bundle laser finally are mapped on the identical space coordinates point.
Laser range sensor receives the reflected light that is produced by 785nm near-infrared laser generator, measures the distance that tested skin surface and vein are searched device; The infrared light transducer[sensor group is measured tested skin surface to the absorbance of near infrared light; Respectively the parameter that records is passed to controller then, controller calculate the threshold value of respective regions by signal processing and upgrade automatically before threshold value, the measurement parameter that controller receives according to diverse location, zones of different calculates the threshold value that this position, this zone absorb near infrared light.When the scanning element position does not have blood vessel, the reflection of near-infrared laser is stronger relatively; When there is blood vessel the scanning element position, near-infrared laser is by strong absorption, its reflex strength relatively a little less than.The vein blood vessel place is arranged under skin, and the average of the near-infrared light intensity that the near infrared light sensor receives is not closed visible laser less than threshold value; Do not have the vein blood vessel place under skin, the average of the near-infrared light intensity that the near infrared light sensor receives is then closed visible laser greater than threshold value; By quick scanning, there are vein blood vessel and no vein blood vessel position to form the clear accurate demonstration vein blood vessel of visual contrast.
