Among the figure: infrared laser 1, visible laser 2, line scanning mirror 3, field scanning mirror 4, Infrared Detectors 5, completely reflecting mirror 6, dichroism reflecting mirror 7, control unit 8, skin area to be scanned 9, rear orientation light 10, vein blood vessel 11, iraser track while scan 12.
The specific embodiment
As shown in Figure 1, the iraser that infrared laser 1 in the dual-color laser scanning type medical vein display equipment sends is through 7 reflections of two-phase color mirror sexual reflex, the visible laser that visible laser 2 sends sees through two-phase color mirror sexual reflex 7 again and forms the conllinear light path with aforementioned iraser through completely reflecting mirror 6 reflections.Light beam is reflected successively by line scanning mirror 3, field scanning mirror 4 and arrives skin area 9 to be scanned with certain track scanning, and skin area to be scanned 9 tops are provided with Infrared Detectors 5, are used for surveying the variable signal of rear orientation light 10.Infrared laser 1, visible laser 2, line scanning mirror 3, field scanning mirror 4, Infrared Detectors 5 are by control unit 8 controls.
Described infrared laser 1 uses solid state laser or semiconductor laser, and the wavelength representative value is 800～900nm.Visible laser 2 uses semiconductor laser, and wavelength can be any visible light wave range, and the wavelength representative value is got 633nm.The beam spots diameter of infrared laser 1 and visible laser 2 is 1～2mm.Infrared laser 1, visible laser 2 are two discrete laser instrument by the synthetic conllinear light path of optics, or can constitute in infrared band tunable laser of tuning wavelength in the visible light wave range scope by one.If adopt the twin-laser form, just need the light beam synthesis system shown in completely reflecting mirror 6 among Fig. 1, the dichroism reflecting mirror 7.6 is the high reflectivity mirror for selected visible light wave range, and 7 are one and can allow specific visible light by allowing the dichroism reflecting mirror of specific infrared light reflection.Two-beam is to make two-beam have the identical direction of propagation and conllinear by the effect of closing beam system.
Line scanning mirror 3, field scanning mirror 4 are the galvanometer scanning galvanometer of a pair of X-Y two dimension, or MEMS (microelectromechanical-systems) galvanometer or photo-electric scanning galvanometer.Wherein line scanning mirror 3 is responsible for line scanning, and field scanning mirror 4 is responsible for field scanning.Two galvanometers just can scan required two-dimentional pattern with certain scanning rule combination.Iraser track while scan 12 on the skin area 9 to be measured specifically can be a formula line by line as shown in Figure 2, also can be two-way serration type as shown in Figure 3.Dual mode respectively has advantage: the formula scanning element is apart from evenly accurate line by line, and the serration type scanning speed is very fast.
Infrared Detectors 5 is single infrared receiving diode, infrared reception audion, or linear array or the face battle array be made up of them.When infrared laser scanning track and vein blood vessel intersected, Infrared Detectors 5 can detect the variation of back scattering optical signal.Infrared Detectors 5 can directly receive the variation of back scattering optical signal and pass to control unit 8.
The concrete composition of control unit 8 as shown in Figure 4.It mainly is made of devices such as microcontroller MCU, 8 and above analog-digital converter ADC and 8 and above digital to analog converter DAC.One road ADC is responsible for detectable signal is imported MCU, and two-way DAC is responsible for the control of line scanning mirror 3, field scanning mirror 4 respectively in addition.The driving power of infrared laser 1, visible laser 2 is also controlled by MCU.
The demonstration of vein blood vessel track can be divided into dual mode.In first kind of mode, scanning probe and two processes of scanning demonstration are carried out respectively, and when scan light scanned venous locations in the detection process, detector sent signal to control unit, and the latter writes down the coordinate figure of current scanning spot of position, and preserves successively.Open visible laser afterwards, give the controller of scanning device successively, make the inswept successively above-mentioned coordinate points of visible light scanning light spot, and multiple scanning repeatedly the position coordinate value of storage before.Because the eye storage characteristic of human eye, the visible light scanning light spot can demonstrate a track on the skin table of vein blood vessel position.Particular flow sheet such as Fig. 5.
In the second way, scanning probe and two processes of scanning demonstration are carried out synchronously, promptly in the scanning probe process, in case detect the back scattering variable signal of vein blood vessel, open visible laser by control unit at once, go out a visible point of light in this position display, the opening time is decided by luminous point size and scanning speed.In the iraser scanning probe, visible light laser shows the pointwise of vein blood vessel position.This mode requires iraser to form the two-dimensional scan zone by grating scanning mode, and scanning line spacing is enough little.Particular flow sheet such as Fig. 6.
The result of above-mentioned dual mode is the track that demonstrates a visible light laser spot in the vein blood vessel position, and medical personnel can judge the accurate position of vein blood vessel according to this track.Dual-color laser scanning type medical vein display equipment based on this principle has accurate positioning, clear display and observes advantages such as convenient.Be applied to the clinical burden that can effectively alleviate doctor and patient, reduce the doctor-patient dispute that causes because of operate miss.
