Description

technical field

[0001] The invention belongs to the field of medical auxiliary equipment manufacturing, and relates to a superficial vein imaging device, in particular to an image navigation device applied to venipuncture operations. Background technique

[0002] Venipuncture is a common medical method, and intravenous injection is widely used in daily medical treatment. It is not easy to perform venipuncture accurately and quickly in clinical practice. Foreign statistics show that the first-time puncture failure rate of ordinary adult intravenous injection is 28%; the first-time puncture failure rate of children's intravenous injection is 44%; The proportion of intravenous injection required more than 3 times was 43%; during intravenous injection, the proportion of "missing needle" phenomenon was 23-28%; the proportion of complete puncture failure in cancer patients was 12%; among hospitalized patients, three days after admission The rate of puncture difficulty was 25%; th...
