Problems solved by technology

In the prior art, composite caps often use a composite film or pull-ring structure, and the composite film or the pull-ring is torn off during infusion or dosing for needle insertion to expose the rubber stopper, but the structure of the composite film is more complicated to produce and the cost is relatively high. High, the pull ring structure is easily damaged during production and transportation

Abstract

Disclosed are a single-folding-handle type infusion assembling cover and a preparation method thereof. The assembling cover comprises an outer cover, an inner cover and a rubber plug. The outer cover is composed of a cover body, a folding handle and a rubber plug chamber. The size of the rubber plug chamber is the same as the size of the rubber plug, and the rubber plug is placed in the rubber plug chamber. A folding line is arranged at the joint of the folding handle and the cover body, holes are formed in the upper portion of the cover body of the outer cover below the folding handle, and the inner cover is placed inside the outer cover and is tightly attached to the lower portion of the rubber plug. Further, pits are formed in the upper surface of the rubber plug, the holes correspond to the pits, and the size of the diameter of each hole is the same as the size of the diameter of each pit. The preparation method of the single-folding-handle type infusion assembling cover includes the steps that raw materials and additives are made to form a uniform mixture, bracing bars are squeezed out, water cooling is conducted, granule cutting and drying are carried out to obtain an inner cover material and an outer cover material, and injection molding is further directly achieved according to the shape of the inner cover and the shape of the outer cover. The assembling cover is convenient to use, needle inserting is convenient during transfusion, chippings are reduced, the preparation technology of the assembling cover is simple and convenient, and the prepared assembling cover is free of deformation, non-discoloring, high in strength and high in safety in the sterilization treating process at the temperature of 121 DEG C.

Description

technical field [0001] The invention generally relates to the technical field of medical packaging, and in particular to a single-folding-handle combined infusion cap and a preparation method thereof. Background technique [0002] Infusion therapy has been widely used in medical activities. The infusion method has gone through the development process from open, semi-open to fully closed, and the infusion set has changed from the initial glass bottle to the current non-PVC composite film. soft bag. When using the infusion bag, in order to realize the infusion, the soft bag is generally provided with a combination cover connected with the interface of the infusion bag, so that it is convenient for adding medicine or inserting a needle. In the prior art, composite caps often use a composite film or pull-ring structure, and the composite film or the pull-ring is torn off during infusion or dosing for needle insertion to expose the rubber stopper, but the structure of the compos...
