Description
Technical field
This utility model belongs to medical assistance checkout gear, relates to a kind of human vein visualizer.
Background technology
Obtain extensively and generally apply at the transfusion of medical procedure medium-sized vein, vein haemospasia, all kinds of puncturing operation.Current vein searching and puncture working mainly rely on professional training and the working experience of medical personnel.Due to the difference of medical personnel's quality and experience, the one-time success rate of venous transfusion, vein haemospasia, all kinds of puncturing operation is lower, shows according to relevant statistics: average adult's intravenous puncture failure first rate is about about 28%; The rate of puncture failure first of children intravenous injection is about 44%; The ratio that the puncture of cancer patient falls flat is up to about 12%; In addition, be the one of the main reasons that many people are reluctant to donate blood because fearing repeatedly venipuncture.The main cause that success rate of venous puncture is lower can be summed up as " difficulty is looked for " of patient's vein.
Therefore facilitating, accurately find patient's vein place and its trend, is improve venous transfusion, vein haemospasia, all kinds of puncturing operation once successful key point.Meanwhile, the one-time success rate of raising venous transfusion, vein haemospasia, all kinds of puncturing operation can reduce conflict between doctors and patients largely, effectively improves the efficiency of medical services, has positive effect to the raising of medical service level.
Utility model content
This utility model is for the technical deficiency of current industry of medical care, utilize modern photoelectric detecting technology provide a kind of safe, convenient, use human vein detecting instrument simple, with low cost, find human vein place fast, accurately to reach, thus improve the success rate of venous transfusion, vein haemospasia, all kinds of puncturing operation.
Technical solution of the present utility model is achieved in that
A kind of human vein visualizer, comprises multiband redness and infrared spaced light-emitting diode group, all mating plate, the infrared CCD with infrared filter, signal processing single chip, rotatable lcd screen, adjustable support.Red and infrared spaced light-emitting diode group be arranged in ringwise be with infrared filter infrared CCD around, equal mating plate is horizontally set on the below of the infrared CCD being with infrared filter, infrared CCD connects Single Chip Microcomputer (SCM) system, and Single Chip Microcomputer (SCM) system can be regulated by detection sensitivity adjusting knob; Single Chip Microcomputer (SCM) system is with rotatable LCD display and signal output interface.
Multiband infrarede emitting diode cohort is made up of the light emitting diode that can send red light that wavelength is 640 ~ 940nm and infrared mixed light, and its medium wavelength is the impact that the red light of 640 ~ 760nm can reduce skin colour to a certain extent.
Multiband infrarede emitting diode cohort can be sent out uniform in light emission and be diffused into whole surveyed area by equal mating plate, and reduces the impact of skin reflex light.
Infrared CCD with infrared filter obtains the infrared light image of tissue reflection, and converts thereof into the signal of telecommunication.
Single Chip Microcomputer (SCM) system process receives the picture signal of infrared CCD, in the original image obtained, thus shows slightly dim because the ability of deoxy-hemoglobin absorption near infrared light in venous blood exceedes HbO2 Oxyhemoglobin.After Single Chip Microcomputer (SCM) system carries out calculation process to the original image obtained, original image medium-sized vein is shown slightly after dim venous information is resolved and carry out color transformed process acquisition vein image comparatively clearly again.The vein image comparatively clearly obtained and original image are carried out information fusion by Single Chip Microcomputer (SCM) system, while truly retaining original image other parts, (particularly containing the image of operating apparatus), video picture is clear in the picture to make vein, and gives rotatable LCD by the image data transmission of fusion.
Rotatable lcd screen is responsible for the vein tissue in fusion image comparatively clearly to show.Can left and right ± 45 °, 0 ~ 120 °, front and back rotate lcd screen can medical personnel be facilitated largely to use.Because being through the fusion image of process, so the operational motion of vein image, medical personnel and instrument positions also can clearly show on the lcd screen in the lump clearly, medical personnel's eyes remaining light while attention operation can observe the positional information of lcd screen, and timely adjustment operation is to reach exact operations.
Instrument support can make human vein visualizer move up and down and left rotation and right rotation, enables limbs of patient rest area be in collection best region as much as possible.
This utility model utilizes the ability of deoxy-hemoglobin absorption near infrared light in human vein blood to exceed this principles of science of HbO2 Oxyhemoglobin, and the achievement in conjunction with contemporary optics and electronic technology develops.Use this utility model that the place, position of vein and operating apparatus " can be seen " intuitively, alleviate labor intensity and the stress of medical personnel, improve the work efficiency of medical personnel; Misery and the intense strain of patient can be alleviated, reduce complication; Reduce the time that medical personnel find vein, improve the treatment survival rate of the critical sick and wounded.
This utility model structural design is simple, detection speed is fast, accuracy of detection is high, reliability is higher.

Detailed description of the invention
During use, patient by needing venipuncture, the limbs of injection or puncture are placed on limbs of patient rest area; The redness that light-emitting diode group is mass-sended out and infrared light are evenly diffused into whole surveyed area by equal mating plate, and reduce the impact of skin reflex light.Infrared CCD with infrared filter obtains the infrared light image being absorbed by limbs, reflect; By the infrared CCD of band infrared filter, infrared signal is transformed into the signal of telecommunication and exports to 4. Single Chip Microcomputer (SCM) system, show slightly dim because the ability of deoxy-hemoglobin absorption near infrared light in venous blood exceedes the HbO2 Oxyhemoglobin original image medium-sized vein that thus infrared CCD obtains; After Single Chip Microcomputer (SCM) system carries out a series of calculation process such as differential transform, linear transformation and histogram transformation to original image, carry out color transformed process acquisition vein image comparatively clearly again by showing slightly in original image after dim venous information is resolved.Single Chip Microcomputer (SCM) system forms the fusion image containing comparatively clear vein and operating apparatus and show the image confession medical personnel reference of merging at rotatable LCD display after the vein image comparatively clearly parsed and original image being merged.If the inadequate definition of image of display, is not enough to Medical treatment, can by regulating detection sensitivity adjusting knob to obtain satisfied fusion image.If patient has a well filled-out figure or slight of stature, limbs of patient rest area can be changed to be applicable to all kinds of patient by conditioning instrumentation support.Information shown by rotatable LCD display can be outputted to the display devices such as projector, large screen television or monitor, for the observation and learning activities such as teaching, scientific research provide information by signal output interface.
