Embodiment 1

[0051] The substrate of embodiment 1 comprises 0.1 weight part diionic macromolecule, 70 weight parts plasticizer, the polyvinyl chloride of 100 weight parts, the epoxy soybean oil of 2 weight parts, the calcium zinc stabilizer of 3 weight parts and 0.7 weight part Parts of stearic acid, wherein the epoxy value of epoxidized soybean oil is 6.6, and the iodine value is 5.0. The above-mentioned diionic polymer is manufactured according to the method disclosed in Taiwan Patent Publication No. TW I496819B (provided by Prebo Biotechnology Co., Ltd.), wherein the melting point of the diionic polymer is 93.58°C. Before use, sieve the diionic polymer through an 80-mesh sieve.

[0052] At 80° C., the diionic polymer and the plasticizer were separately mixed for 25 minutes to obtain a first mixture. Next, the first mixture, polyvinyl chloride, epoxidized soybean oil, calcium zinc stabilizer, and stearic acid were mixed, and a second mixing step was performed at 110° C. for 25 minutes, ...

Embodiment 2 to Embodiment 5

[0054] The base material and the manufacturing process of the PVC sheet of embodiment 2 to embodiment 5 are the same as embodiment 1, and the difference is that the usage amount of the diionic polymer of embodiment 2 to embodiment 5 is respectively 0.2 weight part, 0.3 weight part, 0.5 parts by weight and 1.0 parts by weight.

Abstract

The invention relates to an anti-adhesion material, a medical catheter containing the same and contacting with human tissues and a manufacturing method of the medical catheter. The material is characterized in that: a double-ion polymer with a specific melting point is firstly mixed with a plasticizer and then mixed with polyvinyl chloride, so that the dispersibility of the double-ion polymer in the anti-adhesion material is improved, and therefore, the anti-adhesion material can achieve better tensile strength, tensile rate and anti-adhesion effect of the anti-adhesion material by using a small amount of double-ion macromolecules.

Description

technical field [0001] The present invention relates to an anti-adhesion material, in particular to an anti-adhesion material containing an anti-adhesion polyvinyl chloride composition, a medical catheter containing it and a manufacturing method thereof. Background technique [0002] Polyvinyl chloride (PVC) has the characteristics of soft texture, good elasticity, and high plasticity. It is not only difficult to deform, break and / or break, but also has the advantage of mass production due to low cost, so it is widely used in disposable medical equipment. The above-mentioned disposable medical devices are often used as medical catheters in contact with human tissues, such as tracheostomy tubes, nasogastric tubes and urinary catheters, etc., to maintain hygiene and safety. However, these medical devices that come into contact with human tissues are likely to cause non-specific adhesion of biomolecules, leading to problems such as bacterial infection and / or blockage, resultin...
