Embodiment Construction

[0016] Such as figure 1 As shown, the infrared laser emitted by the infrared laser 1 in the two-color laser scanning medical vein display device is reflected by the dichroic reflector 7, and the visible laser emitted by the visible light laser 2 is reflected by the total reflection mirror 6, and then transmitted through the dichroic The polar reflector 7 forms a collinear optical path with the aforementioned infrared laser. The beam is sequentially reflected by the line scanning mirror 3 and the field scanning mirror 4 and scanned to the skin area 9 to be scanned with a certain trajectory. An infrared detector 5 is arranged above the skin area 9 to be scanned to detect the change signal of the backscattered light 10 . The infrared laser 1 , the visible light laser 2 , the line scanning mirror 3 , the field scanning mirror 4 , and the infrared detector 5 are all controlled by the control unit 8 .

[0017] The infrared laser 1 uses a solid-state laser or a semiconductor laser ...

Abstract

The invention discloses a two-color laser scanning type medical vein display device. The infrared laser emitted by the infrared laser is reflected by the dichroic reflector, and the visible laser emitted by the visible light laser is reflected by the total reflector, and then passes through the dichroic reflector to form a collinear optical path with the infrared laser, and the beam is scanned The mirror and the field scanning mirror sequentially reflect and scan to the skin area to be scanned. An infrared detector is arranged above the skin area to be scanned. The infrared laser, visible light laser, line scanning mirror, field scanning mirror, and infrared detector are all controlled by the control unit. The present invention can be used in clinical diagnosis and treatment to help medical staff quickly and accurately find the exact position of the patient's venous blood vessel, and is especially suitable for infants, obese and dark-skinned patients. The invention has high precision, can be displayed in real time, and is convenient to use, can effectively improve the speed and precision of venous blood vessel positioning, and reduce the possible burden on both doctors and patients in medical links such as intravenous injection.

Description

technical field [0001] The invention relates to medical equipment, in particular to a two-color laser scanning medical vein display device. Background technique [0002] In the process of clinical diagnosis and treatment, it is very common to find blood vessels, such as intravenous injection and blood drawing. Clinically, some patients such as infants, obese and dark-skinned patients will cause the surface of blood vessels to be unclear, making it difficult to directly observe and distinguish with the naked eye, causing great trouble to medical staff, often leading to operational errors or repeated operations, and increasing the burden on doctors and patients. burden on both sides. [0003] Chinese patent No. 03242235.0 titled "Venipuncture Guiding Apparatus" and patent No. 200420072576.1 titled "Medical Vein Detecting Device" disclose their respective vein detecting devices. Both of these solutions adopt direct irradiation of infrared light sources, and rely on detectors ...
