Peripheral vein fixing compressor for plasma exchange

Abstract

The invention relates to a peripheral vein fixing compressor for plasma exchange, which belongs to the technical field of medical instruments. The peripheral vein fixing compressor comprises a supportplate and a fixing component, the support plate is a rectangular plate made of hard materials, and the fixing component comprises a first fixing band arranged on the front end of the rectangular plate and a second fixing band arranged on the rear end of the rectangular plate, the first fixing band and the second fixing band both comprise a left fixing band and a right fixing band, hook-and-loop fasteners are arranged on the left fixing bands and the right fixing bands, the left side or the right side of the rectangular plate is provided with a third fixing band, the rectangular plate is provided with a fixing base, and the fixing base is provided with a catheter fixing plate, the catheter fixing plate is provided with a plurality of inserting grooves and at least one inserting strip. Theperipheral vein fixing compressor of the invention can be used to fix the elbow joint and maintain the puncture position, and the situation that a puncture needle is displaced to puncture the blood vessel is prevented; meanwhile, the peripheral vein fixing compressor can also be used to press the puncture position for rapid hemostasis, then the working efficiency is improved, which can provide help for relieving the increasing shortage of medical staff at the present stage.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a device for fixing and compressing peripheral veins during ophthalmic plasma replacement. Background technique [0002] Plasma exchange refers to taking the patient's blood out of the body, separating the plasma and blood cells through a special device, discarding the plasma, and then transfusing the blood cells and newly supplemented normal plasma back into the body in order to remove the pathogenic factors in the patient's body and achieve the purpose of treating the disease . The use of plasmapheresis in the treatment of autoimmune diseases of the nervous system is increasing, and the efficacy is remarkable. [0003] Optic neuritis (ON) is mostly a severe immune-mediated idiopathic demyelinating and necrotic disease, often with acute or subacute vision loss, and is the most likely blinding optic nerve disease in young and middle-aged people, seriously affecting The ...
