Venipuncture System Based on Pressure Field Detection

Abstract

The invention relates to a venipuncture system based on pressure field detection, which is characterized in that it comprises: a plurality of infrared cameras fixed in a treatment room; a detection device having a detection surface with a variable shape, and the detection surface is arranged in a matrix perpendicular to the detection surface The three-dimensional pressure sensor; the pressurizing device, which is used to apply pressure to the local skin at a certain position near the proximal end of the puncture vein; the main control device; the puncture device, the main control device controls the puncture device to operate the puncture needle according to the puncture point, puncture angle and puncture path Puncture the skin, subcutaneous tissue, and vein in turn. The invention can realize precise positioning of veins and automation of arterial puncture, without the need for medical personnel to operate, saving medical resources; during the detection process, the compliance of veins can be calculated to exclude venous lesions, and the specific positions of veins and puncture needles can be calculated during the puncture process, without Misoperation occurs and postoperative complications are reduced.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a venipuncture system based on pressure field detection. 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 posterior wall o...

Problems solved by technology

[0003] At present, medical staff generally use two methods when performing venipuncture: one is the visual method, which is to use naked vision to find and locate blood vessels. This method is only suitable for superficial and prominent veins. For patients, the size, bending and bifurcation of blood vessels in the subcutaneous tissue cannot guarantee accurate positioning; there is also a touch method, which uses the feeling of touch to find and locate blood vessels. This method requires many years of clinical experience. By touching the skin to distinguish blood vessels and the touch of surrounding tissue, so as to determine the location and depth of blood vessels
