Problems solved by technology

If the concave and convex strips are provided on the entire inner surface of the bag body, the transparency of the bag body will be destroyed, that is, the visibility of the situation inside the bag will be affected, making it difficult to confirm the abnormality of the recovered dialysis effluent (waste fluid), and causing 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 a pair PVC liquid medicine storage bag. The outer surface of a PVC peritoneal dialysis solution storage bag and the outer surface of a PVC waste liquid storage bag are respectively provided with a layer of silicone rubber membrane coating, or a layer of the silicone rubber membrane coating is arranged on the outer surface of one of the PVC peritoneal dialysis solution storage bag and the PVC waste liquid storage bag. A layer of the silicone rubber membrane coating is arranged on the inner surface of the PVC waste liquid storage bag. The invention further discloses a corresponding anti-adhesion material and an operation process of the anti-adhesion material. According to the technical scheme, the inner surface of the PVC waste liquid storage bag and the outer surfaces of the storage bags are respectively coated by the layer of an isolating membrane of silicone rubber, the phenomena that adhesion occurs between the PVC liquid medicine storage bag, and the PVC waste liquid storage bag after high-temperature sterilization and the PVC liquid medicine storage bag and the PVC waste liquid storage bag are difficult to separate are prevented from happening, and the phenomenon that waste liquid cannot be easily filled into the PVC waste liquid storage bag due to the fact that the interior of the PVC waste liquid storage bag is in adhesion after the high-temperature sterilization is prevented from happening. Due to the fact that the silicone rubber membrane is high in tolerable temperature, the silicone rubber membrane can play a good role in adhesion prevention, and stripping can be smoothly carried out on two bags or on the interior of a bag. Due to the fact that the silicone rubber membrane is good in transparency, observation of the PVC waste liquid storage bag is not influenced. Stacking, warehousing and transportation of products are not influenced.

Description

technical field [0001] The invention belongs to the technical field of medical appliances and medical supplies, and relates to the technology of medicine packaging and containers. More specifically, the invention relates to a double-connected PVC medicine 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 [0002] 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 every moment, similar to normal kidneys. In this way, the patient's dietary restrictions are not as harsh as hemodialysis. [0003] Continuous Ambulatory Peritoneal Dialysis (CAPD): It is currently the most commonly used perito...
