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 inner diameter, 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

Embodiment 2
[0050] Example 2: Puncture of superficial forearm vein
[0051] After collecting the data of the patient's age, gender, height, weight, bust circumference, waist circumference, and subcutaneous fat thickness, input it into the main control device.
[0052] 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.
[0053] The treatment room is controlled to a certain temperature. Multiple infrared cameras are set at fixed positions in the treatment room for high-frequency synchronous imaging. The fixed position of the treatment bed is set with reference to the infrared light source, and the collected image data is input into the main control device. The main control device uses the human body contour recognition technology to calculate the patient's body position information, and processes multiple groups of two-dimensional images to ...
Embodiment 3
[0058] Example 3: Dorsal Vein Puncture of Foot
[0059] After collecting the data of the patient's age, gender, height, weight, bust circumference, waist circumference, and subcutaneous fat thickness, input it into the main control device.
[0060] 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.
[0061] The treatment room is controlled to a certain temperature. Multiple infrared cameras are set at fixed positions in the treatment room for high-frequency synchronous imaging. The fixed position of the treatment bed is set with reference to the infrared light source, and the collected image data is input into the main control device.

Abstract
The invention relates to a venipuncture system based on temperature field detection, which is characterized in that it includes a treatment room in which the indoor temperature is kept at a set temperature; a plurality of infrared cameras fixed in the treatment room; a detection device with a detection surface with a variable shape , temperature sensors arranged in a matrix on the detection surface; a pressurizing device, used to apply pressure to the local skin at a certain position near the proximal end of the punctured vein; a main control device; a puncture device, the main control device controls the puncture according to the puncture point, puncture angle and puncture path The device operates the puncture needle to puncture the skin, subcutaneous tissue, and vein in sequence. 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 temperature 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 wal...
