example 1

[0069] Example 1: Superficial vein puncture on the back of the hand

[0070] 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, and a predetermined position on the treatment bed is set with a reference infrared light source. The collected image data is sent to the server, and the server processes multiple sets of two-dimensional images to calculate the three-dimensional contour information of the human body. The human body contour recognition technology calculates the position in...

[0076] Example 2: Superficial forearm vein puncture

[0077] 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 on the puncture side. Multiple infrared cameras are set at fixed positions in the treatment room for high-frequency synchronous imaging, and a predetermined position on the treatment bed is set with a reference infrared light source. The collected image data is sent to the server, and the server processes multiple sets of two-dimensional images to calculate the three-dimensional contour information of the human body. The human body contour recognition technology calculates the position information of each part of the patient's b...

[0083] Example 3: Dorsal Vein Puncture of the Foot

[0084] 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, and a predetermined position on the treatment bed is set with a reference infrared light source. The collected image data is sent to the server, and the server processes multiple sets of two-dimensional images to calculate the three-dimensional contour information of the human body. The human body contour recognition technology calculates the position information of each part of the pati...

Abstract

The invention provides a venipuncture system based on a near infrared spectroscopy. The venipuncture system based on the near infrared spectroscopy utilizes good permeability of a near infrared band spectrum on human tissue and the differences of optical properties of different tissue molecules according to the band spectrum for optical algorithm analysis, and the vein route can be calculated to operate venipuncture. Based on the venipuncture system, precise locating of veins and puncture automation can be achieved, the operation of medical workers is not needed, and medical resources are saved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a venipuncture system based on near-infrared spectrum 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 posteri...
