Can the "needling robot" be able to clear the venous blood needle with one needle?

  If the nurse is inexperienced, or the patient is young, fainted, and the blood vessels are not obvious, the process of venous blood collection may become extremely difficult. In order to solve these problems, a research team developed an automatic blood sampling device, and recently published the results of the human leave test.

  The advent of a new type of medical equipment provides hospital blood collectors and clinicians with a new technology for accurate and accurate blood collection at one time. This technological invention is particularly important in dealing with the variety of difficult operations that need to be handled when venous blood collection from patients of different ages. The improvement of the accuracy of the blood collection process will greatly reduce the patient's discomfort, and at the same time can shorten the blood collection time and save costs. A research team from VascuLogic (LLC) has developed an automatic venipuncture medical instrument in the world, which can automatically complete the venous blood collection process for blood collection or placement of venous blood collection needles. The results of in vitro and in vivo verification studies (including verification experiments on human subjects) show that the accuracy of the device to complete blood collection is higher than 95%, and is better than the control group of manual blood samples. 56% of adults and 82% of children suffer from injection phobia (needle fainting), that is, fear of needles. This is just one of the problems that clinicians face when drawing blood. Researchers from LLC, through a concentrated survey of 200 American blood collectors, realized that for many children, it is difficult to smoothly perform venous blood collection is a very significant problem, especially when children are afraid of pain and take a long time. And the difficulty in getting the needle smoothly or the need to get the needle multiple times leads to emotional anxiety for the patient and parents. At the same time, studies have confirmed that parents’ acceptance of the effectiveness and safety of this device is higher than 98%. The safety of this new device is the team’s top priority-a device to fix the arm. During the injection process Real-time tracking of 3 milliseconds per time and disposable sterile sleeves to prevent cross-infection between patients are some of the safe configurations adopted by the equipment. In the early stages of design, one of the challenges that researchers faced was real-time vein imaging and modeling technology. This equipment relies on high-quality fine imaging of the vein and its surrounding area to ensure the accuracy of venipuncture. The research team used ultrasound technology and vein three-dimensional (3D) reconstruction technology to improve the imaging effect, enabling the "automatic blood sampling instrument" to achieve real-time detection and complete accurate venipuncture, successfully avoiding the need for multiple venipuncture to collect blood. LLC The company’s CEO Tim Maguire said: “This automatic venipuncture instrument is very encouraging for us because it effectively relieves parents and children’s anxiety during the venipuncture process. For those who cannot For children and their families who do not suffer from the pain of needle sticking or repeated needle sticking, the fear and resistance to doctors cannot be ignored. Therefore, any effort that we can do to make them feel relaxed is of great benefit, especially When children are afraid of needles or need long infusions."

  Although the device was originally designed for children's hospitals, it can also be used by adult patients. What needs to be adjusted is to choose an appropriate injection needle tube according to the patient. This automatic venipuncture instrument can greatly improve the entire blood collection process, save costs, and more importantly, greatly comfort the emotions of parents and children who have difficulties in conventional venipuncture.
