Problems solved by technology

Not only is the stainless steel mold used for liquid injection molding very expensive, it is also very inflexible since the mold cannot be modified once it is made
High mold input costs and inflexibility of molds make it difficult to manufacture new silicone MEC products and make it difficult to continuously improve silicone MEC after the initial design
Also, silicone cannot be used to make "Texas MECs" because such MECs require thinner and longer sheaths

Abstract

The invention relates to a male external urinary catheter and a manufacturing method thereof. The male external urinary catheter is made of nitrile rubber, and the nitrile rubber includes the following components and raw materials in weight percentage: 15-45% solid raw material, the balance is water. The solid raw material includes the following components in parts by weight: 80-100 parts of butadiene-acrylonitrile copolymer, 0.2-3.0 parts of sulfur, 0.2-2.0 parts of zinc oxide, dibutyl titanate butyldithioamino 0.1-2.0 parts of zinc formate, 0-2.0 parts of zinc diethyldithiocarbamate, 0-3.0 parts of titanium dioxide, 0-3.0 parts of antioxidant, and 0-5.0 parts of potassium hydroxide. The male external urinary catheter and the manufacturing method thereof provided by the present invention do not cause problems such as induction of allergies, are thin in thickness, comfortable to wear, and low in cost.

Description

technical field [0001] The invention relates to a male external urinary catheter, in particular to a male external urinary catheter and a manufacturing method thereof. Background technique [0002] Male external urinary catheter (hereinafter referred to as MEC), also known as condom MEC, is specially designed for men to deal with urinary incontinence. The proximal end of one type of MEC is a thin, tubular, condom-like sheath that is worn over the penis of a male patient. Its distal end is like a thicker funnel with a small tube or just a straight tube that connects to a urine bag. Another type of MEC, called the Texas MEC, has a distal end that is just a straight tube made of plastic or rubber without a funnel. The sheath is longer than a normal MEC and is connected by the machine to the straight pipe with a plastic insert. In order to prevent the MEC from falling off the penis and prevent urine leakage during wearing and use, the patient can use a strap to tie the MEC sh...
