Blood flow control elastic O type ring

Abstract

The invention provides a blood flow control elastic O type ring. The blood flow control elastic O type ring aims at providing a device used for blood expelling and blood stopping in limb operations and increasing the returned blood volume to maintain the blood-supply of important organs in hemorrhagic shock. A hollow straight pipe adopting medical silicone rubber is put into an O type ring upper-lower mold compression molding forming mold, the two ends of the medical silicone rubber hollow straight pipe are vulcanized through rubber injection mould compression, and the formed new medical silicone rubber component tightly connects the two ends of the medical silicone rubber hollow straight pipe. When the blood flow control elastic O type ring is used for rolling blood expelling from the heat distant end to the heat proximal end of the limb, the stress of the O type ring at any rolling positions are the same, the centripetal pressure to the limb is constant, the sliding process is easy and smooth, and the blood expelling effect is reliable.

Description

technical field [0001] The invention relates to an elastic O-ring, in particular to an elastic O-ring for blood flow control, and belongs to the technical field of medical devices. Background technique [0002] At present, the O-ring is usually molded by upper and lower molds. The O-ring molded by the upper and lower molds is set on the distal end of the human body. When the O-ring is rolled from the distal end to the proximal end to expel blood, due to The outer diameter stress is different, rolling will be very difficult, and the centripetal pressure on the limbs is also not constant. During the rolling process, there will be a state of one tight and one loose, which will affect the effect of expelling blood. Contents of the invention [0003] The purpose of the present invention is to provide a device for driving blood to stop bleeding during limb surgery and increasing blood return to the heart to maintain blood supply to important organs during hemorrhagic shock.
