Problems solved by technology

This method is complex, and the image quality is limited by the frequency of the scanning mirror, which cannot meet the actual real-time observation requirements
At the same time, the device uses a laser generator with high power, and improper operation may easily cause medical accidents.

Embodiment 1

[0069] like figure 1 As shown, the vein navigator includes three main components: a casing 1 , an optical path structure 2 , and a core circuit board 3 . Wherein, both the optical path structure 2 and the core circuit board 3 are fixed in the casing 1 .

[0070] like figure 2 The casing 1 mainly includes a lower casing 11 , a liquid crystal display panel 12 , and an upper cover 13 . Then by pulling off the upper cover 13 image 3 As shown, the housing 1 also includes a connecting plate 14 . Among them, the lower housing 11 is a cavity with a U-shaped structure, and its main function is to install the optical path structure 2 and the core circuit board 3. The upper cover 13 is connected to the lower housing 11 through four corresponding threaded holes at the bottom, and is installed on its U. On the shaped opening, a closed cavity is formed to protect the internal optical path structure and circuit board. The liquid crystal display panel 12 is installed on the front end o...

Embodiment 3

[0101] like Figure 9 The schematic diagram of the optical structure, the projected optical path 52 is horizontally emitted to the reflector 53, refracted at 90 degrees, and emitted from the optical window 54; the camera optical path 51 is directly emitted from the optical window 54, and the refracted optical paths 52 and 54 are parallel to each other. It is emitted from the optical window, so there is a fixed distance difference between the two in the horizontal direction, which can be realized through software compensation. The specific software compensation method uses a calibration plate for calibration and correction.

[0102] A vein image acquisition and display device, comprising a lower casing 11 and an upper cover 12 matched with the lower casing 11, the bottom of the lower casing 11 is provided with an optical path window 113, and the bottom of the lower casing 11 is provided with a connecting plate 14, The connecting plate 14 is provided with an optical path base pl...

Abstract

The invention discloses a device for vein navigation. A skin area exposed to an infrared light source is obtained through a sensitization device, an image is transmitted to a microprocessing unit, undergoes processing of an image algorithm, such as enhancement, extraction and reconstruction, is transmitted to a projection module and is projected to an image collecting area through the projection module, and it is guaranteed that the projected image and an originally collected image coincide under the working distance conditions. A method for vein navigation is further disclosed. According to the device and method for vein navigation, doctors are assisted to operate blood vessels, the device has the advantages of being compact in structure and good in real-time performance, and the processed image can be completely projected to the surface of the skin according to the proportion of 1:1.

Description

technical field [0001] The invention relates to the field of medical care equipment, in particular to a venous blood vessel navigation device and method. Background technique [0002] In clinical diagnosis, treatment and nursing, intravenous injection, puncture, blood drawing, etc. are all very common operations, in which it is necessary to find the patient's blood vessels before processing, but some patients are clinically special, and it is difficult to directly judge with the naked eye Its location and depth bring considerable difficulty to these treatments, such as infants with small blood vessels, obese people with thick subcutaneous fat, and terminal cancer patients. Therefore, during treatment, the operation is often repeated, and the error rate is high, which makes the patient endure the pain caused by the operation many times, and also makes the relationship between the doctor and the patient tense, increasing the burden on both sides. [0003] In order to solve th...
