example 1

[0061] Example 1: Superficial vein puncture on the back of the hand

[0062] The data collection unit collects the patient's age, gender, height, weight, chest circumference, waist circumference, and subcutaneous fat thickness data and puncture site information, and sends them to the server. Except for the contraindications of venipuncture, the patient was prompted by electronic voice to maintain a supine position on the treatment bed, exposing the skin of the forearm and the back of the hand on the puncture side. Multiple infrared cameras are set at fixed positions in the treatment room for high-frequency synchronous imaging. The predetermined position on the treatment bed is set with reference to the infrared light source, and the collected image data is sent to the server. Contour recognition technology calculates the position information of each part of the patient's body, and calculates the position information of the treatment bed, the braking device, the detection devic...

[0073] Example 3: Dorsal Vein Puncture of the Foot

[0074] The data collection unit collects the patient's age, gender, height, weight, chest circumference, waist circumference, and subcutaneous fat thickness data and puncture site information, and sends them to the server. Except for the contraindications of venipuncture, the patient was prompted by electronic voice to maintain a supine position on the treatment bed, exposing the skin of the calf and dorsum of the puncture side. Multiple infrared cameras are set at fixed positions in the treatment room for high-frequency synchronous imaging. The predetermined position on the treatment bed is set with reference to the infrared light source, and the collected image data is sent to the server. Contour recognition technology calculates the position information of each part of the patient's body, and calculates the position information of the treatment bed, the braking device, the detection device, the disinfection device, the pu...

Abstract

The invention provides a vein puncture system based on infrared thermal imaging technology. The vein puncture system of the invention is based on infrared thermal imaging technology, taking a human body as radiation source, detecting heat radiation emitted by the human body at work, without changing any parameters of the measured object. The system is harmless to human body and environment, and the thermal scanning process is simple, quick and sensitive, and does not require special preparation. After a series of signal processing, the invisible temperature change of body surface is transformed into visible infrared thermogram, and the vein course is calculated and venipuncture is carried out based on the infrared thermogram. The vein puncture system based on the invention can realize veinprecise positioning and puncture automation, and does not need medical personnel to operate, thus saving medical resources.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a venipuncture system based on infrared thermal imaging technology. Background technique [0002] Patients with difficulty in venipuncture include: infants, children, obese patients, edema patients and other patients who are not easy to see the veins themselves, or patients who have undergone repeated chemotherapy, patients with poor blood vessel elasticity, first aid, shock, sharp decrease in blood volume, and blood vessel collapse patient etc. When venipuncture, avoid joints, induration on the skin surface, scars, vein valves, vein branches, and veins with diseased vein walls. Failure of venipuncture can lead to venipuncture complications such as: phlebitis, hemorrhage and hematoma, effusion, tissue necrosis, or catheter blockage. Common reasons for venipuncture failure: unskilled puncture technique, which damages the needle tip; excessive puncture punctures the poste...
