Positioning device for vein puncture needle position

Abstract

The invention discloses a positioning device for a vein puncture needle position. The positioning device for the vein puncture needle position is characterized in that the positioning device for the vein puncture needle position comprises an infrared source, a main camera, a side camera and an image processing unit; the infrared source is used for irradiating the skin surface and a needle of a puncture area; the main camera is used for taking a picture for the needle above the skin surface of the puncture area from top to bottom; the picture taking direction of the side camera is perpendicular to the picture taking direction of the main camera, and the side camera is used for taking a picture for the needle from the horizontal direction of the skin surface of the puncture area; the image processing unit is connected with the main camera and the side camera, and the image processing unit is used for comparing the pictures taken by the main camera and the side camera to obtain the position of the needle. The positioning device for the vein puncture needle position has the advantages of being simple in structure, accurate in positioning, capable of being reused just through replacing the needle, low in cost and usage cost, high in efficiency, and intuitive and accurate and the like.

Description

technical field [0001] The invention belongs to the field of medical care equipment, and more specifically relates to a device for locating the position of a venipuncture needle. Background technique [0002] In clinical diagnosis, treatment and nursing, it is very common to perform venipuncture on patients, but some patients have clinically inconspicuous vascular features, such as small blood vessels in infants and young children, and thick subcutaneous fat in obese people, which directly makes it difficult for doctors to directly puncture with the naked eye. Judging the position and depth of the blood vessel and the needle, especially when puncturing, cannot accurately obtain the position information of the needle. [0003] The U.S. Patent No. 20140100524 is an invention patent, which uses a veinviewer medical vein display device, and cooperates with the infrared light transmitted by the infrared optical fiber on the puncture needle to locate the puncture needle. However, ...
