Description

An integrated excitation and monitoring device for limb ischemia adaptation

technical field

The utility model belongs to the technical field of medical devices, in particular to an integrated excitation and monitoring device for limb ischemia adaptation.

Background technique

Remote ischemic conditioning (remoteischemicconditioning, RIC) refers to the phenomenon that the ischemic injury of distant organs can be improved by administering one or more short-term non-lethal ischemia-reperfusion treatments to an organ or tissue. In 1986, Murry et al. reported for the first time that when the left circumflex branch of the heart was treated with ischemia-reperfusion in dogs, it was found that the infarction of the left anterior descending branch could also reduce the infarct size. Later studies found that RIC intervention on organs other than the heart can also improve ischemic injury in the heart, and it was also found that RIC intervention has similar effects on ischemic injury in kidneys, lungs, brain and other important organs. In recent years, a number of clinical randomized controlled trials have also suggested that RIC intervention can significantly improve the ischemic injury of heart, lung, brain and other organs in adult patients. In recent years, studies have also found that RIC has a certain preventive effect on intestinal ischemic necrosis diseases in children such as necrotizing enterocolitis and midgut torsion. Therefore, RIC is a new method that can be applied to the clinical treatment of ischemic organ injury in children.

Currently, the RIC method used in children is a safe and minimally invasive intervention on the limbs. The RIC excitation and monitoring are completed by using the existing clinical blood pressure cuff to inflate and deflate to keep the pressure. The main process is to bind the blood pressure cuff to one limb of the child, and observe the changes in blood pressure by inflating and deflated the blood pressure cuff to achieve the ischemia and reperfusion effect on the remote limb. When measuring blood pressure, it is best not to Put the cuff of the sphygmomanometer in direct contact with the patient's skin through the clothes, and the lower edge of the cuff should be 2 to 3 cm above the elbow fossa, and the tightness of the cuff should be appropriate, so that the measured blood pressure value will be It is more accurate; but when measuring in spring, autumn and winter, due to the inconvenience of undressing, the blood pressure is generally measured by wearing a thicker sweater, but the error of measuring blood pressure through a thick coat is relatively large; it is very inconvenient for children to take off their clothes in winter, and The effect of ischemia and reperfusion on the distal limbs through blood pressure observation has a large error, and the effect is greatly reduced. Therefore, there is an urgent need for an integrated limb ischemia excitation and monitoring device that is suitable for different seasons and is easy to carry, especially suitable for children.
