Viewpoint conventionally, because the physiological structure of palm is thicker, in order to ensure that the HONGGUANG of luminous tube can penetrate palm muscle, realize the identification to vein, then need luminous tube to have very high luminosity, make luminescence component be irradiated to the luminous flux of the centre of the palm enough large.The luminous tube operating power of existing product often reaches about 20 volt-amperes, but so large operating power causes luminous tube power consumption large, and heating is serious, the shortcomings such as working life is low, and due to luminous tube luminosity very large, the HONGGUANG of leaking at work can damage the eyes of medical worker.This is a contradiction, the technique direction one of current this contradiction of solution is the luminous tube adopting luminous efficiency higher, enough luminosity are obtained with less operating power, and more advanced technology adopts sensitiveer CCD photographic head to replace eyes, gather the light of palm back of the body transmission, demonstrate image on a display screen again, although this can reduce luminous tube power consumption greatly, but technical sophistication, cost is high, and need to be shown by display screen on one side, when observing and venipuncture will be carried out while the vein of location, because operating point (the palm back of the body) and display screen be not at same position, operate and just seem very not directly perceived.
Summary of the invention
The object of the invention is openly so a kind of vein observation device, it can with more low power luminous tube realize HONGGUANG opponent palmaris meat penetrate realize vein observe.
Through the further analysis to vein observation device operation principle, prior art adopts enhancing luminous flux to ensure, and the viewpoint penetrated of HONGGUANG opponent palmaris meat is also not bery accurate, determine in fact whether HONGGUANG can penetrate the deciding factor of palm muscle, is the light intensity of incident illumination instead of total luminous flux.Because light is constantly being decayed through muscular tissue Light intensity, only have the HONGGUANG initially entering palm to reach the threshold values of certain light intensity, guarantee HONGGUANG can penetrate whole palm decaying to before naked eyes do not see.So what determine that can HONGGUANG penetrate palm is light intensity instead of luminous flux.Certainly, in theory, when light-receiving area (i.e. palm penetration surface) is certain, luminous flux is direct ratio with light intensity, but in fact, applicant adopts special mode, under ensureing that illumination beam has the prerequisite of enough light intensities, reduce total luminous flux, can realize with the luminous tube of lower operating power the object that HONGGUANG penetrates palm, not only economize on electricity but also can reduce costs and reduce cooling requirements.(cost of high-power light-emitting pipe is higher).
According to above-mentioned analysis, the present invention improves vein observation device, and it comprises the main frame of vein observation device, and be the observation platform carrying out vein observation for placing palm above main frame, main frame includes luminescence component, and luminescence component includes luminous tube; It is characterized in that: described luminescence component includes reverberation bowl and light penetrating panel, the inner face of light penetrating panel is provided with reflector, reflector includes the parallel to each other fence that is in the light of strip, and being in the light between fence is fence gap, and the inner face of the fence that is in the light is with reflector layer.
Reflector be in the light fence width between 1 to 5mm, fence gap width is between 1 to 5mm.
Described light penetrating panel is plane or arc surfaced, and correspondingly reflector is also plane or arc surfaced.
Described reverberation bowl is taper reverberation bowl, and its inner surface is with reflector layer.
Design considerations of the present invention is: through observing, when vein is observed, because the diameter of palm vein has one fixed width, and be genesis analysis with palm, does not need very meticulous resolution when observing.So, applicant devises the reflector of fence structure, the illumination beam sent not is evenly distributed on whole light penetrating panel, but is penetrated by fence gap, present many parallel gratings, and grating namely move towards (also palm vein move towards) with palm vertical.And due to the inner face of the fence that is in the light be reflector layer, so be radiated at the light of the fence inner face that is in the light, be all reflected back, then reflected by the reflector layer of reverberation bowl, again penetrated by fence gap.So meaning of the present invention is: concentrate injection owing to irradiating light from fence gap, under the prerequisite that the luminous luminous flux of luminous tube is the same, the light intensity of the illumination beam of injection can be improved, and injection illumination beam light intensity the same can meet vein observe prerequisite under, then can reduce the operating power of luminous tube, realize the meaning of economize on electricity and reduction luminous tube cost.(in theory, 50% can be economized on electricity when the fence width that is in the light is equal with fence gap width).And from each grating of fence gap injection, because grating is namely move towards (also vein move towards) with palm vertical, as long as to each other apart from not too large, just can meets the requirement of vein observation to resolution, not affect observation work.
accompanying drawing explanationfig. 1 is the structural representation of venipuncture auxiliary observation device.
