Wearable portable vein imager

Abstract

The invention discloses a wearable portable vein imager. The wearable portable vein imager includes a vein image collection system, an image processing module, a projection display device and a powersupply which are all integrated on a spectacle frame; according to wearable portable vein imaging glasses, a near-infrared light supplementing lamp gives out light, a point light source is diffused toan area light source through a light guide plate to illuminate a target area, after being absorbed and reflected by a human body, the light passes through a near-infrared light filter, imaging is conducted through an image sensor, a controller collecTS and then caches an image, and after pixel space transformation, image filtering and image intensification are conducted through the image processing module, the image is output through the projection display device finally. The wearable portable vein imager has the advantages of clear imaging, no need for other auxiliary devices, small volume,light weight, long-time wearability, low cosTS and the like.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a wearable portable vein imager. Background technique [0002] Intravenous injection is a widely used medication method at present, and exists in various medical occasions widely. Intravenous injection must first find the position of the patient's vein in order to accurately puncture the vein and reduce the patient's pain and discomfort. However, for some patients, such as obese patients, infants, patients after chemotherapy, patients with edema, patients with cardiovascular weakness, patients with excessive blood loss, etc., it is difficult to find veins only by visual observation, and it generally requires repeated pricking attempts , Judging the position of the needle by the return of blood, which not only increases the pain of the patient, but also aggravates the tension between the doctor and the patient, and is not conducive to the timely administration of medicine...

AI Technical Summary

Problems solved by technology

[0005] In addition, this design also has problems such as large volume and complex structure, and it cannot be called a glasses-type vein imager, which greatly limits the application occasions.

[0006] The invention patent with the application number 201410802193.2 discloses a kind of medical vein finding glasses, which uses two controllable light sources to irradiate the target area, receives reflected light through the coated spectacle lens coated with a filter film, filters out light of other wavelengths, and only allows the fixed The designed wavelength of light passes through to achieve the purpose of vein display. The near-infrared light used is 500-610nm and 660-900nm, which belong to the overlapping band of visible red light and invisible red light. The red light reflection contrast of skin and blood vessels is different. Obviously, it is difficult to apply the display effect in high-demand medical occasions only by direct viewing with human eyes. Judging from the disclosed technical details, it is difficult to achieve the ideal vein display effect if it is not used with other imaging equipment. , compared with existing vein imaging equipment, it does not have the above-mentioned advantages
