Abstract

The invention discloses an adjustable medical annular hemostat which comprises an upper semicircular plate, a lower semicircular plate, a telescopic mechanism and a fixing mechanism. Compared with the prior art, the adjustable medical annular hemostat has the advantages that the telescopic mechanism is utilized, an upper clamping plate moves downwards by adjusting a telescopic rod, limbs are tightened by the upper clamping plate and the lower clamping plate, and excessive bleeding at wounds is prevented; a first telescopic spring and a second telescopic spring are adopted for slightly lifting the clamping force between the upper clamping plate and the lower clamping plate in the blood return process of the limb, backflow of veins is facilitated, meanwhile, an elastic ball of the upper clamping plate is driven by a telescopic rod to slide into the bottom of the lower clamping plate, and therefore the clamping force between the upper clamping plate and the lower clamping plate is reduced. Wherein the bouncy ball has certain softness, so that the lower clamping plate can be pressed down and rebounded, and vein blood can be relaxed and refluxed.

Description

technical field [0001] The invention relates to the field of medical technology, in particular to an adjustable medical annular hemostat. Background technique [0002] Traditionally, large extremity arterial and venous bleeding, and for the convenience of transporting the wounded, the tourniquet method is often used. The tourniquet is made of medical polymer material natural rubber or special rubber, long and flat, with strong stretchability. It is suitable for infusion, blood drawing, blood transfusion in medical institutions in routine treatment and treatment, and one-time use for hemostasis; or emergency hemostasis for limb bleeding, wild snake bite bleeding, tourniquet hemostasis is simple, An effective method of hemostasis, which achieves the purpose of hemostasis by blocking the blood flow by compressing blood vessels. However, if used improperly or for too long, the tourniquet can cause ischemia, necrosis, and disability of the distal limbs. Therefore, the tournique...
