Abstract
The diagnostic apparatus for torsion of testis is a venous blood vessel imaging system formed from near infrared semiconductor light-emitting diode, correspondent near infrared ray receiver and monitor, in which the wavelength of said near infrared semiconductor light-emitting diode is 850 nm, its power is 120 mw and its emitting angle is 20 deg. The near infrared receiver is a black-white low-illuminance high-analysis camera in which the front of its lens is equipped with a 800 nm infrared ray filter. Its diagnosis is accurate and reliable.
Description
Technical field
The present invention relates to a kind ofly can detect the whether normal instrument of circulation of local venous blood, especially can detect whether normal testicular torsion diagnostic apparatus of male testical inner blood circulation.
Background technology
Testicular torsion is perplexing many male, especially child, this sick genesis mechanism is: after arteriovenous is reversed in the testis, arterial blood is under-supply, the not smooth congestion of venous return, causing necrosis of testis. existing this sick method of diagnosis is to inject contrast agent in testicular vessel, and this has just brought great misery to patient.This in addition method also exists following drawback: the irradiation of 1.x ray; 2. cost an arm and a leg; 3. patient is extremely painful; 4. contrast agent may cause anaphylaxis; 5. complicated operation.
Summary of the invention
The purpose of this invention is to provide a kind of principle science, simple to operate, low price, make patient avoid the testicular torsion diagnostic apparatus of all miseries of bringing because of diagnosis.
For achieving the above object, the vein blood vessel imaging system that the present invention is made up of near-infrared semiconductor light-emitting-diode and corresponding near infrared ray receptor and monitor.The wavelength of near-infrared semiconductor light-emitting-diode is 800nm, and power is that 120mw, emission angle are 20 degree.The near infrared ray receptor is the high video camera of resolving of black and white low-light (level) that 800nm infrared ray colour filter is housed before the camera lens.
Adopt said structure, because principle of the present invention is: near infrared ray penetrates the tissue of human body, and the hypoxia hemoglobin absorption peak in venous blood is the highest, so can develop on monitor.
In sum, advantage of the present invention is: the principle science, observe directly, accuracy of judgement, simple and convenient, low price and can not bring any misery to patient.
Description of drawings
Below in conjunction with accompanying drawing to further detailed explanation of the present invention.
Figure is a structural representation of the present invention.
1. monitors, 2. power supplys, 3. video cameras among the figure
4. camera lens 5. infrared ray colour filter 6. near-infrared semiconductor light-emitting-diodes
The specific embodiment
Among the figure, the vein blood vessel imaging system that the present invention is made up of near-infrared semiconductor light-emitting-diode 6 and corresponding near infrared ray receptor and monitor 1.The wavelength of near-infrared semiconductor light-emitting-diode 6 is 850nm, and power is that 120mw, emission angle are 20 degree.The near infrared ray receptor is the high video camera 3 of resolving of black and white low-light (level) that 800nm infrared ray colour filter 5 is housed before the camera lens 4.Image presents by monitor 1.When concrete operations, plug in 2 earlier, under camera lens, shine penis, as have testicular torsion with near-infrared semiconductor light-emitting-diode 6 multi-angles, then visible vein reverses in monitor, and blood back is not smooth, congestion.
Claims (3)
1. testicular torsion diagnostic apparatus, the vein blood vessel imaging system of forming by near-infrared semiconductor light-emitting-diode and corresponding near infrared ray receptor and monitor.
2. a kind of testicular torsion diagnostic apparatus according to claim 1 is characterized in that: the wavelength of near-infrared semiconductor light-emitting-diode is 800nm, and power is that 120mw, emission angle are 20 degree.
