Problems solved by technology

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 Difficult puncture occurs in 25% of cases; low puncture success rate is the biggest reason why many people do not want to donate blood

Abstract

The invention discloses a superficial vein shooting device. The superficial vein shooting device comprises a PCB, a near infrared LED, a lamp shade, a lens installing base, a solid image sensor, a color filter and an imaging lens set. The color filter and the imaging lens set are installed in a same lens cone. The imaging lens set is installed at the front end of the lens cone. The color filter is installed at the rear end of the lens cone. The brightness of the near infrared LED can be adjusted, and shadowless lighting is obtained through the lamp shade. Superficial veins can be shot.

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...
