Vein vessel depth measuring device and blood sampling machine

Abstract

The invention provides a vein vessel depth measuring device and a blood sampling machine and relates to the technical field of medical equipment. An imaging device and a control system connected with the imaging device are included. The imaging device comprises a support and a camera arranged on the support. The control system comprises an image processing module and a correction module. The image processing module comprises a foreground extraction module and a depth measuring and calculating module. The foreground extraction module is used for receiving an original target image collected by the camera and forming a foreground extraction graph of a target area. The depth measuring and calculating module receives the foreground extraction graph and obtains depth data of target subcutaneous vein vessel depth by conducting processing and calculation on the foreground extraction graph. The correction module is used for receiving the depth data and obtaining accurate depth data of the target subcutaneous vein vessel depth by conducting processing and calculation on the depth data. According to the vein vessel depth measuring device, the vein vessel depth is worked out through image processing technology, thus puncturing work can be more efficient, and the puncturing accuracy rate is increased greatly.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a venous blood vessel depth measuring device and a blood sampling machine. Background technique [0002] In clinical medicine, when collecting blood or intravenous infusion, medical personnel need to perform venous blood vessel puncture, and when performing puncture work, medical personnel generally use naked eye observation and hand touch to judge the position and depth of blood vessels, and perform puncture work based on experience. Therefore the success rate of puncture mainly depends on the experience of medical personnel, but the accumulation of the puncture experience of medical personnel needs a long time. Moreover, each person's physique is different, and the depth of blood vessels is also different, so the puncture work is not easy to operate, and the accuracy of puncture is not guaranteed. [0003] Although many universities in China are currently studying th...

Therefore, the success rate of puncture mainly depends on the experience of medical staff, but the accumulation of medical staff's puncture experience takes a long time

Moreover, each person's physique is different, and the depth of blood vessels is also different, so the puncture work is not easy to operate, and the accuracy of puncture is not guaranteed.

[0003] Although many universities in China are currently studying the issue of venous vessel enhancement and projection display, and now there are some venous vessel image enhancement and projection display equipment to assist in the puncture work, but the depth information of the venous vessel is still uncertain. Unable to effectively improve puncture efficiency and puncture accuracy
