preparation example Construction

[0027] The preparation method of single-folding handle without inner cap type infusion combined cap and interface comprises the following steps:

[0028] Step 1: Mix the outer cover raw materials and outer cover additives to form a uniform mixture, feed the mixture into a twin-screw extruder at 190-230°C, extrude the strands, and cool the strands to 40-60°C ℃, pelletize, and blow dry to obtain the outer cover material, which is injected into the outer cover material according to the shape of the outer cover to obtain the outer cover of the single folding handle type infusion combination cap;

[0029] Step 2: Mix the mixture of interface raw materials and interface additives evenly, feed the mixture into the twin-screw extruder at 190-230°C, extrude the strands, cool the strands to 50°C with water, pelletize, and blow air drying to obtain the interface material and injecting the interface material according to the shape of the interface to obtain the infusion interface.

Abstract

The invention relates to an infusion combined cover with a single folded handle and without an inner cover, and an interface. The combined cover comprises an outer cover and a rubber plug, wherein the outer cover consists of a cover body, a folded handle and a rubber plug chamber; the cover body is provided with a fixed clamping groove and a positioning clamping groove; fold is formed at the connection position of the folded handle and the cover body; a hole is formed in the upper part of the cover body; the rubber plug is positioned in the rubber plug chamber; the interface comprises a fixed seat, a liquid pipe and a connecting part; the connecting part is provided with a fixed clamping buckle and a positioning clamping buckle; the fixed clamping groove is matched with the fixed clamping buckle; the positioning clamping groove is matched with the positioning clamping buckle. Furthermore, a pit is formed in the upper surface of the rubber plug. A preparation method of the combined cover and the interface comprises the steps of mixing raw materials and additives into a uniform mixture; extruding and performing bar drawing, performing water cooling, dicing and drying to obtain an outer cover material and an interface material; performing injection moulding according to the shapes of the outer cover and the interface. The combined cover and the interface are simple in structure and convenient to use; a needle is convenient to insert during infusion; the interface and the combined cover are connected firmly; the preparation process is simple and convenient; the prepared combined cover and interface have high strength and high safety.

Description

technical field [0001] The present invention generally relates to the technical field of medical packaging, in particular to a single folding handle without an inner cap type infusion combined cap and interface 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 an infusion bag combination cover and an interface matched with it, so that it is convenient for adding medicine or inserting a needle. In the prior art, the combined cover is mainly composed of an outer cover, a rubber plug, and an inner cover, which has a complicated structure and high production cost, and the connection between the i...
