Embodiment 1

[0037] The embodiment of the present invention provides a method for manufacturing a double-lens multi-spectral imaging lens group. The double-lens multi-spectrum imaging lens group is used in a vein display system. It includes two lenses, one of which is used for near-infrared light. It filters the visible light and condenses the visible light; the other lens is used to filter the visible light and condense the near-infrared light.

[0038] Such as figure 1 As shown, the manufacturing method of the double-lens multispectral imaging lens group specifically includes:

[0039] S1. Take a piece of glass sheet 101 with high light transmittance and flat surface as the base. After cleaning the glass sheet 101 with water and acetone, place it in an oven and bake at 130°C for 10 minutes to remove water vapor and residual acetone; natural cooling Then, the positive photoresist 102 is spin-coated on the glass sheet 101, the method of spin-coating is firstly at a speed of 500 rpm for 10 secon...

Embodiment 2

[0051] The embodiment of the present invention provides a vein display system based on a double-lens multispectral imaging lens group, under which two pictures can be obtained at the same time under one shot, one is a color picture seen by the naked eye under visible light , The other is a black and white picture of human veins under near-infrared light. Then through a special image processing algorithm, the veins in the near-infrared image are first extracted, and then the extracted veins are superimposed on the color picture through image fusion technology, and the processed fused image is displayed on the monitor in real time, so that it can be real To restore the distribution of human veins. Through this system, the vein images displayed can assist doctors in disease diagnosis and injection, especially for children, whose veins are small, and the system can clearly show the position of the veins.

[0052] Such as figure 2 As shown, a vein display system provided by an embod...

Abstract

The invention relates to a method for manufacturing a double-lens multi-spectral imaging lens set and a vein display system thereof. The vein display system comprises the double-lens multi-spectral imaging lens set, and further comprises a light source assembly, an image sensor, an image processing system and a display device. Two lenses in the double-lens multi-spectral imaging lens set respectively have an optical path, each lens can collect different light, one of the lenses is used for filtering near-infrared light and collecting visible light, and the other lens is used for filtering the visible light and collecting the near-infrared light. During one imaging, near-infrared images and visible light images can be obtained at the same time. The two lenses are identical in optical parameter, and the sizes and the positions of the images are basically consistent. Accordingly, the two lenses can be fused through an image processing technology conveniently, enhanced display of local veins of a human body can be achieved, the display effect close to that of human eye observation can be achieved as a whole, and medical staff are assisted in finding corresponding positions during vein puncture.

Description

Technical field [0001] The invention relates to the field of medical equipment, in particular to a manufacturing method of a double-lens multispectral imaging lens group and a vein display system thereof. Background technique [0002] More than one hundred years ago, human medical advancement began to use vascular puncture to draw blood and infuse blood, physiological saline and other liquids. However, the key to implementing this medical technology is to find the blood vessels of the human body before needle puncture. The blood vessels undergo subsequent treatment. [0003] There are two main methods of locating blood vessels in clinical use: [0004] 1. Visual method: Find and locate blood vessels with naked eyes. This method is only suitable for patients with superficial and prominent veins. The size, curvature, and bifurcation of blood vessels in the subcutaneous tissue cannot be guaranteed at a glance. [0005] 2. Touch method: Find and locate blood vessels with the feeling of ...
