Description

TECHNICAL FIELD

[0001] The utility model belongs to the medical instrument technical research field, concretely relates to an inflatable radial artery far end adjustable pressure bandaging device. BACKGROUND

[0002] Radial artery far end puncture is a kind of interventional vascular operation technique currently used more in clinical, i.e. through the radial artery (radial fossa) at the far end of the back of the hand as the site of arterial access of interventional technology. And selecting radial artery far end puncture has unique advantages compared with traditional femoral artery and radial artery puncture. Compared with femoral artery puncture, radial artery far end puncture is located in the distal site away from the heart, the risk of operation-related complications is relatively low, and the possibility of postoperative pain and bleeding of patients also correspondingly reduces. At the same time, it avoids the damage and infection risk of lower limb nerves, blood vessels and deep tissues caused by femoral artery puncture. Compared with radial artery puncture, radial artery far end puncture is easier to operate and monitor, and the control of catheter position during operation is more convenient, and the risk of bleeding is also lower. In addition, radial artery far end puncture is located in the wrist position, and the postoperative activity degree of freedom of patients is higher, and the recovery period is more comfortable. Therefore, selecting radial artery far end puncture as the puncture position of intravascular intervention treatment not only helps to reduce the operation risk of patients and improve the treatment effect, but also can improve the operation experience and postoperative comfort of patients.

[0003] Although radial artery far end puncture has many advantages compared with other puncture methods, it still has some problems, of which the most prominent is that the bandaging is inconvenient. Because the radial artery far end is located in the radial fossa, the anatomical structure at the puncture point is not as stable as the wrist, which leads to that the bandaging pressure is not easy to control during the bandaging process after the operation ends, and it is not easy to be stably fixed. If the bandaging is too tight, it may cause insufficient blood supply to the hand, increase the risk of hand ischemia, especially for patients who need repeated puncture or long-term placement of catheter. And if the bandaging is too loose, it is easy to cause bleeding at the puncture point after the operation, which increases the probability of postoperative complications, and brings inconvenience to the comfort and safety of patients after the operation.
