Medical drainage bag catheter joint

Abstract

The invention discloses a medical drainage bag catheter joint, which comprises the following components in parts by weight: 20-30 parts of poly(p-dioxanone), 30-40 parts of vinyl modified star-shapedpolylactic acid, 10-15 parts of carboxyl rubber, 3-5 parts of a thermal stability modifier, 5-8 parts of a nano additive, 10-20 parts of polyester fibers and 1-3 parts of an antioxidant. According tothe medical drainage bag catheter joint, through reasonable formula design and preparation process adjustment, the mechanical strength and toughness of the medical drainage bag catheter joint are effectively improved, the excellent connecting effect can still be achieved after repeated connection and use of the medical drainage bag catheter joint, and the situations of air leakage, urine leakage,deformation or disengagement and the like are avoided; the medical drainage bag catheter joint can be effectively recycled or biodegraded after being discarded, so that environmental pollution is effectively reduced, and the medical drainage bag catheter joint has the advantages of being safe, environmentally friendly and excellent in comprehensive performance.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a catheter joint of a medical drainage bag. Background technique [0002] Drainage bag, the English name Urine Bags, refers to the commonly used disposable drainage bag (urine bag). The drainage bag includes a protective cap (including joints) made of medical polymer materials, a drainage catheter, a film bag body, a check valve (configured according to customer needs), a drain valve (if equipped with a drain valve), buttons (legs) Hanging type, waist hanging type), straps (leg hanging type) or sling (waist hanging type), used for clinical patients to store urine. [0003] Catheter joints are effective joints that connect various parts in the drainage bag, and it is necessary to ensure the tightness of the connection and prevent urine leakage. The existing conduit joints have the following problems during use: 1. Low mechanical strength, resulting in poor connection stability a...

AI Technical Summary

Problems solved by technology

The existing conduit joints have the following problems during use: 1. Low mechanical strength, resulting in poor connection stability and the possibility of tripping during use; 2. Poor toughness, easy to deform after repeated connections several times, 3. It cannot be effectively recycled, because the drainage bag is usually a disposable product and consumes a lot. If the material cannot be recycled, it will avoid causing a large amount of solid waste, pollute the environment, and is not environmentally friendly.
