Abstract

The invention relates to a tearable special-shaped balloon for alleviating human soft tissue damage and a preparation method thereof. A special-shaped balloon blank composed of a balloon blank, two adjacent sub-balloon blanks are connected by a linear tearable part, and then a balloon molding machine is used to perform air injection blow molding on each of the sub-balloon blanks; The obtained tearable special-shaped balloon is mainly composed of a plurality of sub-balloons, and two adjacent sub-balloons are connected by a linear tearable part. The preparation method of the tearable special-shaped balloon for alleviating human soft tissue injury is simple, the surface of the prepared tearable special-shaped balloon is uneven, the stability at the transplant site is better, it is not easy to slip off, and can be multi-pointed during exercise. It has a better buffering effect under force, and the tearable special-shaped balloon can be cut, which can relieve different types and degrees of soft tissue damage in a targeted manner.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and relates to a tearable special-shaped balloon for reducing human soft tissue damage and a preparation method thereof. Background technique [0002] After repeated strenuous movements, delicate soft tissues are often damaged by wear and tear by rubbing against each other and / or hard tissues such as bone. Torn tendons of the rotator cuff and ruptured joint capsules are examples of such injuries. Additionally, inflammation, infection, disease, and / or genetic predispositions to degeneration of these tissues can adversely affect these tissues. [0003] In order to solve the above problems, the patent CN104473704A discloses a prosthesis (balloon) for reducing human soft tissue and other tissue damage. For expansion, the filler can be gas, liquid or gel. This kind of gap filling can indirectly improve the smooth movement of joint tissues and relieve pain caused by joint discomfort. The mai...
