Embodiment Construction

[0031] The present invention provides an adaptive exposure control method and system for a subcutaneous vein imaging device. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0032] like figure 1 As shown, the subcutaneous vein imaging apparatus includes an image acquisition system (110), a central control system (120) and a projector (130). Wherein, the image acquisition system (110) includes a near-infrared light filter (111) and an infrared imaging camera (112). The projector (130) includes a projection imaging element (131), a dichroic prism (132), visible light sources (133, 134), a near-infrared light source (135), a beam splitter (136) and a projection lens (137). The image acquisition syste...

Abstract

The invention discloses a self-adaptive exposure control method and system for a subcutaneous vein imaging machine. The self-adaptive exposure control method and system for the subcutaneous vein imaging machine can be used for solving the following problems but not limited to the following near-infrared light illumination problems which are caused by individual differences of puncture objects, different actual operation conditions and inconsistent conditions such as imaging distances and angles of different areas of portions, pending to be punctured, of the puncture objects.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an adaptive exposure control method and system for a subcutaneous vein imaging instrument. Background technique [0002] With the development of medical technology, in the modern medical process, subcutaneous venipuncture has become one of the frequently used medical operations in clinic. In the traditional subcutaneous venipuncture operation, the operator directly locates the subcutaneous venous vessels of the punctured object with naked eyes, but it is often difficult to locate the subcutaneous venous vessels due to reasons such as the punctured object's obesity and skin color. In order to solve this problem, the subcutaneous vein imaging device can assist the operator to locate the subcutaneous vein of the puncture object by improving the contrast between the subcutaneous vein of the puncture object and the surrounding tissue, improving the accuracy of subcutaneous vei...
