Embodiment Construction

[0016] As shown in Figure 1, the infrared laser emitted by the infrared laser 1 in the two-color laser scanning medical vein display device is reflected by the dichroic mirror 7, and the visible laser emitted by the visible light laser 2 is reflected by the total reflection mirror 6, and then transmitted The dichroic mirror 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 with a typical wavelength of 8...

Abstract

The invention discloses a dichroic laser scanning type medical purpose vein display device. Infrared laser sent out by an infrared laser is reflected by a dichroic reflector, visual laser sent out by a visible light laser composes a collinear light path together with an infrared laser group through the dichroic reflector after being reflected by a holophote, light beam is reflected by a line scanning mirror and a field scanning mirror in sequence and scanned to a derma area to be scanned, an infrared detector is arranged at the upper part of the derma area to be scanned, the infrared laser, the visible light laser, the line scanning mirror, the field scanning mirror and the infrared detector are controlled by an infrared detector. The invention can be applied to the clinical diagnosis and is used to help medical care personnel to quickly and accurately find the accurate location of a vein blood vessel, in particular suitable for babies and children, and pyknic type patients and deep complexion patients. The precision of the invention is high, the real-time display can be performed, the operation is convenient, the speed and the precision of the vein blood vessel position can be effectively improved, and the possible burdens of a doctor and a patient for medical links such as intravenous injection are lightened.

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 ...
