Embodiment Construction

[0019] When in use, the operator holds the projected vein indicator and flips the power switch with the thumb to turn on the instrument. At this time, the detection area is irradiated by the red light emitted by the micro-projector module. Move the projected vein indicator, and when the detection area is irradiated to the body, the subcutaneous veins will be displayed on the surface of the body in black and light shades. According to the requirements of the operation, the distance between the projected venous indicator and the body can be adjusted, and it is advisable to keep it 6-30 cm away from the body. If the display of veins is not very clear, the operator can adjust the display sensitivity by using the thumb to adjust the detection sensitivity adjustment knob until a satisfactory display is obtained.

[0020] When two-handed operation is required, the projected vein indicator can be inserted on the stand through the fixed socket with charging electrodes, and the patient'...

Abstract

Disclosed is a projection type vein indicating instrument. The projection type vein indicating instrument comprises a light equalization slice, an infrared light emitting diode group, a hot mirror made of optical glass material, an infrared filter, an infrared CCD (charge coupled device), a micro projector and a single chip computer system, wherein the light equalization slice is located at the bottom, the infrared light emitting diode group composed of infrared light emitting diodes circularly arranged is arranged above the light equalization slice, the hot mirror made of the optical glass material is arranged on the upper portion of the infrared light emitting diode group, the infrared filter is arranged on the hot mirror, the infrared filter is connected with the single chip computer system through the infrared CCD, the infrared light emitting diode group emits infrared light 760-940nm in wavelength, the single chip computer system processes an obtained original image so as to convert the original image into a clear vein image, and the single chip computer system transmits the obtained clear vein image to the micro projector. The projection type vein indicating instrument is simple in structure design, high in detection speed, high in detection accuracy, and high in reliability.

Description

technical field [0001] The invention belongs to an auxiliary medical detection device, which can be widely used in medical and health departments for venipuncture, intravenous infusion and puncture to find hidden subcutaneous veins, improve the success rate of the operation; and visually find the location of the vein in the puncture operation, In order to avoid accurately during the operation. Background technique [0002] In the medical process, intravenous infusion, venous blood drawing, and various puncture operations are widely and commonly used. At present, the work of finding and puncturing veins mainly depends on the professional training and work experience of the operators. Due to the different quality and experience of operators, the one-time success rate of intravenous infusion, venous blood drawing, and various puncture operations is low. According to relevant statistics, the first-time failure rate of ordinary adult intravenous injection is about 28%; The firs...
