Description
Technical field
A kind of the present invention relates to medical supplementary instrument technical field, more particularly to VR imaging vein developing units.
Background technology
During clinic diagnosis, venipuncture is a very common and very important medical care precess.Punctured
During to find blood vessel be very common situation, such as intravenous injection, blood drawing etc..In the case of very urgent, can be quick
Venae subcutaneae blood vessel is correctly found, and is punctured and is successfully even more important.Conventional piercing method is the method for pricking tourniquet, leads to
This method is crossed, the puncture success rate of the very abundant nurse of experience is also higher.But in situations below, even having rich
The nurse of rich experience, puncture success rate are also very low.For example：Venipuncture under dark environment；Dark-complexioned patient, such as black
Ethnic group etc., and the particular location for being difficult to see vein blood vessel clearly.
Patent No. 03242235.0, entitled《Venipuncture inducer》And Patent No. 200420072576.1,
Entitled《Medical vein detecting device》Chinese patent individually disclose respective vein detection device.Both solutions
Infrared light supply direct irradiation is all taken, quiet to find to the detection and analysis of rear orientation light by detector or video camera
The position of arteries and veins blood vessel.

Survey video camera and gather rear orientation light from different directions, then the image to receiving carries out processing the position for obtaining blood vessel and depth
Degree information.Its operation principle is to be radiated at target area by multispectral infrared light supply, and the infrared light is passed through after skin reflex can
See that light ends infrared transmission optical filter and enters video camera, by the skin figure of two camera acquisition difference angles of different angles
Picture, obtains position and the depth information of vein blood vessel after the calculating of processing unit is processed.
Patent No. 200710156506.1, entitled《Dual-color laser scanning type medical vein display equipment》Employ two
The mode of dimension scanning, its operation principle are that the iraser of infrared laser transmitting is reflected through two-phase color mirror sexual reflex, then first
By the reflection of space scanning galvanometer and field scanning vibration mirror reflected, finally with the skin area of certain track scanning patient.Control
Unit can open laser instrument, it is seen that light is successively through optics such as two-phase color mirror sexual reflex, row scanning galvanometer and field scanning galvanometers
Equipment irradiation patient skin region, so that show the positional information of vein blood vessel.
At present, in domestic several schemes, " a kind of multispectral three-dimensional vein display equipment ", " venipuncture inducer " and
" medical vein detecting device " although simple structure, must could observe by certain optics or video camera,
The effect of observation is not directly perceived and clear enough." dual-color laser scanning type medical vein display equipment " although change display mode,
But for nonplanar vein such as the back of the hand radian is displayed without solution well, there is display blind area.
