Problems solved by technology

If the concave-convex strips are provided on the entire inner surface of the bag main body, the transparency of the bag main body will be destroyed, that is, the observability of the situation inside the bag will be affected, and it will be difficult to confirm the abnormality of the recovered dialysis effluent (waste liquid), which will also cause manufacturing waste. The raw material cost of the liquid storage bag increases, and the sealed edge around the bag forms a weak part, which is prone to defects such as air holes

Abstract

The invention discloses an anti-adhesion material of a pair PVC (polyvinyl chloride) medical soup storage bag. The anti-adhesion material is arranged on the outer surfaces of a PVC peritoneal dialysis soup storage bag and a PVC waste soup storage bag or one of the outer surfaces; and a silicone rubber film coating layer is arranged on the inner surface of the PVC waste soup storage bag. The invention further discloses a corresponding operation process. By the above technical scheme, the silicone rubber isolation film is coated with the inner and outer surfaces of the storage bags, and the PVC medical soup storage bag and the PVC waste soup storage bag are prevented from adhesion and being difficult to separate after high-temperature sterilization. The internal adhesion of the PVC waste soup bag to cause waste soup input failure after high-temperature sterilization is avoided. As the silicone rubber film is resistant to high temperature, anti-adhesion function can be well achieved, and the bags and the interiors of the bags can be smoothly peeled. The medical soup storage bag is good in transparency, and observation of the waste soup storage bag as well as stacking, warehousing and transport of products is unaffected.

Description

[0001] This application is a divisional application for the following invention patent applications: [0002] Original application number: 201310199206.7 [0003] The original filing date: May 25, 2013 technical field [0004] The invention belongs to the technical field of medical appliances and medical supplies, and relates to the technology of medical packaging and containers. More specifically, the present invention relates to a double-connected PVC medicinal liquid storage bag. In addition, the present invention also relates to the anti-adhesion material of the double-connected PVC liquid medicine storage bag, and the operation process of the anti-adhesion material. Background technique [0005] Currently, there are two main types of peritoneal dialysis: continuous ambulatory peritoneal dialysis (CAPD) and automated peritoneal dialysis (APD). Both types of peritoneal dialysis are continuous, meaning that excess water and waste are removed from the body at all times, s...
