Abstract
Description
[0001] MACHINE LEARNING SYSTEM AND METHOD FOR BLOOD VESSEL IMAGING AND 3D RECONSTRUCTION FOR ASSITED INTRUSION
[0002] FIELD OF THE INVENTION
[0003] The present invention relates to a system and method for blood vessel imaging and 3D reconstruction for intrusion via an automatic vein cannulation system. More particularly, the present invention provides an advanced automated imaging system and method for performing blood vessel imaging, and 3D reconstruction by utilizing machine learning techniques to increase the accuracy and quality of the system and process for detecting blood vessels for intrusion by an automatic vein cannulation.
[0004] BACKGROUND OF THE INVENTION
[0005] Intravenous (IV) cannulation is a critical procedure for providing venous access in medical settings, essential for various medical purposes such as blood sampling, administering fluids, medications, nutrition and blood products. Every patient who visits a healthcare setting has a potential for intravenous cannulation procedure and related pain, fear, and distress, as access to the blood stream via a needle is perhaps the most common procedure administered by healthcare professionals.
[0006] Establishing intravenous (IV) access in younger patient populations via the traditional cannulation technique is often fraught with challenges, particularly in pediatric patients. Traditionally performed manually by healthcare professionals, the procedure, despite its ubiquity, is fraught with significant challenges and a notable error rate. Studies indicate error rates as high as 34% in general populations, with even higher rates reported in pediatric and geriatric patients, where the failure rate can reach up to 60% (African Health Science, 2020). These high failure rates not only compromise patient safety but also contribute to increased discomfort and potential complications.
[0007] The IV procedure involves the needle puncturing the vein at an angle, followed by advancing the needle-cannula combo until the cannula tip is fully within the vein. However, if the needle's angle is not adjusted during advancement, there is a risk of puncturing the back wall of the vein, resulting in the cannula becoming interstitial.
[0008] Veins consist of three layers: an inner endothelium, a layer of muscle fibers, and an outer connective tissue layer. Venous valves within veins ensure blood flow direction and prevent pooling in extremities, although they can pose challenges during catheter insertion, particularly where veins join or in lower extremities. These challenges underscore the critical need for improved techniques and technologies to enhance the success rates of vein cannulation, minimize patient discomfort, and reduce the risk of complications associated with multiple insertion attempts.
[0009] To combat the issues that arise during cannulation many medical practitioners use simple methods, such as utilizing a warm compress, tourniquets, and mild agitation (slapping) of the vein to increase the likelihood of a successful first pass. While these methods are fairly simple to initiate, cost effective, and unobtrusive to the patient, the low first pass rates indicate other methods need to be explored. As such, technologically enhanced methods are currently in use for better vein visualization including near infrared (NIR), ultrasound, and transillumination technologies. These technologically advanced methods use either sound, in the case of ultrasound, or light, in the case of NIR and transillumination to visualize the vein.
[0010] Near-Infrared Vein Visualization devices allow for non-invasive identification of veins for multiple uses. They function by illuminating the skin with near-infrared light (700-900 nm), which penetrates the skin and subcutaneous tissues to a depth of approximately 3 mm. The light is differentially absorbed by the underlying tissues, with increased absorption by deoxygenated haemoglobin. The difference in absorption is detected by the device camera, and the reproduction is projected onto the subject’s skin in real-time. Infrared (IR) vein visualization is a modality that aids venous cannulation; however, few reports of this technique exist in the infant and toddler population. Therefore, there is a technological gap wherein there is a requirement of an advanced vein detection and guidance systems, utilizing optics, cameras, and imaging technologies, be optimized to accurately locate veins in patients with diverse anatomical challenges, including different hair coverage, skin types, and complexions, particularly in pediatric and geriatric populations. Further, an advanced vein intrusion mechanism is needed to ensure minimal discomfort and high success rates in IV cannulation, particularly in challenging patient populations such as pediatric and geriatric patients. Moreover, implementation of robotics and automated systems in vein cannulation impact the precision and success rates compared to traditional manual techniques.

The robotic arm (108) also incorporates sensors such as but not limited to pressure sensor, blood pressure sensor, temperature sensor, IR sensor or similar to assist in functioning of automated intrusion using machine learning techniques. Furthermore, the robotic arm (108) follows a strict sterility protocol wherein the robotic arm (108) is prepped in a sterile environment, and all tools are sterilized to prevent infection.
[0040] The automated system (100) also comprises of a control unit (110) incorporating plurality of microprocessors to control and automate 3D reconstruction and intrusion of blood vessel using machine learning techniques in real-time. The controller unit (110) further comprises of multiple processors configured to receive and process images acquired by the one or more cameras (104), and configured to maneuver and position the automated robotic arm (108). Further, the controller unit (110) is configured to receive the information from the multiple processors about potential insertion sites, and selects a region of interest and directs the automated robotic arm (108) to insert the needle into the region of interest.
[0041] The controller unit (110) incorporates a neural network configured to process the image recognition and 3D reconstruction of blood vessel and position the needle proximate a targeted location on a patient's skin surface, and guide the automated robotic arm (108) to cause the distal end of the needle to puncture the skin surface and penetrate a desired depth into the blood vessel or tissue at the targeted location in order to avoid, as much as possible, damage to surrounding tissue, blood vessels, and the like.

[0043] The image registration module is responsible for identifying distinctive points or features in each image that can be matched between the monochrome infrared stereo camera (104) pairs; finding correspondences between the descriptors of features detected in the left and right images; and estimating the disparity or depth map that represents the geometric relationship (translation, rotation, and possibly scale) between the images. The distinctive point or feature incorporates parameters such as but not limited to camera intrinsic parameters, camera extrinsic parameters and rotation translation matrix.
[0044] The image library construction module builds a structured collection of images captured by the monochrome infrared stereo camera (104). It involves organizing, categorizing, and potentially annotating captured images to make them easily searchable and retrievable.

[0047] The guided insertion module enables robotic arm (108) to use precise anatomical landmarks and region of interest to guide the needle into the target vein. The module uses sensors and real-time imaging to confirm proper needle placement and integrates feedback from these sensors to adjust the needle placement dynamically. Once the needle is in place, the module uses the robotic arm’s sensors for continuously monitoring blood return to ensure consistent and pulsatile flow, indicating successful venous access. In case the module founds any irregularities, it triggers automatic recalibration or adjustment procedures.
[0048] The needle handling module ensures steady pressure during needle insertion and withdrawal. The module helps the robotic arm (108) to maintain precise control over needle handling, minimizing patient discomfort and reducing the risk of complications. The module also manages the timing of needle ejection with high precision to avoid dislodgement or damage to the vein.
[0049] Altogether, each of the module helps in the calibration of the imaging module (102) follows camera intrinsic parameters, camera extrinsic parameters and rotation translation matrix using machine learning techniques.
