Invagination and fragmentation preventing infusion container combined cover

Abstract

The invention provides an invagination and fragmentation preventing infusion container combined cover, which comprises an outer cover body and an inner cover body, wherein the inner cover body is arranged in the outer cover body; a rubber pad is arranged on the inner cover body; a puncture surface is arranged on the rubber pad; puncture grooves are formed in the puncture surface; the rubber pad is a two-hole type rubber pad; a pull-ring surface is arranged at the upper end of the outer cover body; and a pull ring is arranged on the pull-ring surface. By designing the rubber pad as the two-hole type rubber pad, the depth of the puncture surface of the rubber pad is increased, and since the puncture surface of the rubber pad is an inclined plane, puncture force exerted on the rubber pad is effectively dispersed; a 8-shaped cross section is exposed as the pull-ring surface of the combined cover is torn to be open and the 8-shaped cross section just corresponds to two holes in the puncture surface of the rubber pad, so that doctor personnel can just conduct puncture on the improved puncture surface of the rubber pad; therefore, the problems of invagination and fragmentation of the rubber pad in a puncture process are effectively avoided and medicine liquid is protected from getting contaminated.

Description

technical field [0001] The invention relates to the field of combined caps for transfusion containers, in particular to a combined cap for transfusion containers that prevents the rubber pad from sinking and chipping. Background technique [0002] At present, there are several common types of medical infusion containers used clinically, such as glass bottles, plastic bottles and soft bags. As a traditional packaging material for large infusions, glass infusion bottles have been widely used clinically. However, in the production process, the production environment is relatively open, there are many control points, and the probability of contamination is high; surface peeling and loose caps may also occur, and insoluble particles will be produced after long storage time. In addition, the glass bottle itself is heavy and takes up a lot of space for storage; it is easy to break and the transportation cost is high. It is increasing year by year, and the demand for combined co...

Problems solved by technology

However, in the production process, the production environment is relatively open, there are many control points, and the probability of contamination is high; surface peeling and loose caps may also occur, and insoluble particles will be produced after long storage time

In addition, the glass bottle itself is heavy and takes up a lot of space for storage; it is easy to break and the transportation cost is high. It is increasing year by year, and the demand for combined cover products used in conjunction with it is also increasing correspondingly

The combined caps used for plastic bottles and soft bag infusion containers on the market generally use traditional combined caps (composed of outer caps, inner caps and rubber pads). For dosing or infusion, the medical personnel need to use a large external force to penetrate the inner cover and the rubber pad during the puncture process. During the puncture process, the rubber pad may fall off and the rubber pad may sink, making the entire bottle of infusion unusable. , leading to bad market complaints, seriously restricting the sales of large infusion products, increasing market maintenance costs, and seriously affecting the company's market image
