Description

Technical Field

[0001] The invention relates to the technical field, and in particular to a device for predicting forearm swelling after radial artery puncture and a method for using the device. Background Art

[0002] In coronary artery intervention via femoral artery access, 5% to 10% of patients will experience complications after local puncture of blood vessels, including bleeding, hematoma, pseudoaneurysm, etc., especially the risk of retroperitoneal bleeding, which can lead to death in severe cases. Compared with the femoral artery route, coronary artery intervention via radial artery route has been widely used due to its advantages of less bleeding, fewer vascular complications and lower total mortality. The existing puncture method requires the palm of the patient's finger to bend back as much as possible to tighten the skin at the puncture site and fix the radial artery; then use the fingertip to feel the pulsation of the radial artery to be punctured, and the area where the operator feels the pulsation should be reduced as much as possible to reduce the puncture range, so that it is easy to find the best puncture point. In the existing radial artery puncture operation, it is extremely important to make the radial artery puncture point at the highest point of the horizontal plane, but this requires the patient to fully cooperate with the operator and maintain the upper limb position required by the operator. Although the existing technology uses some auxiliary devices to help patients maintain the required upper limb position, puncture failure often occurs due to pain stimulation during puncture, or due to the patient's own joint condition and involuntary upper limb movement;

[0003] Although the radial artery approach is highly safe, it still has many complications and postoperative care issues, such as forearm swelling, wound pain, bleeding, and numbness of the operated limb. Forearm swelling is the most common. Currently, patients need to record and observe their forearm circumference at regular intervals after surgery to determine the extent of swelling, which requires nurses to perform frequent tests. This not only increases the workload, but also affects the patient's rest. There is a lack of monitoring equipment for the patient's forearm swelling, so timely intervention and treatment cannot be performed, and it is not easy to relieve swelling with cold compresses.
