Description
Technical Field
The utility model belongs to the infusion bag field, concretely relates to combination lid and have infusion bag of this combination lid.
Background
In clinical practice in hospitals, transfusion is still one of important treatment means, and the infusion directly enters the blood of a human body and can spread to the whole body in less than one minute, so that the infusion has the advantages of quick response, accurate dosage entering the body, small dependence on the matching of patients and the like. However, adverse drug reactions are very rapid if they occur. Therefore, the patient often neglects the danger while selecting the infusion to be effective. According to statistics, the adverse drug reaction/event report table 131.7 ten thousand are received by the national adverse drug reaction monitoring network in 2013, wherein the injection accounts for 58.7 percent. Research shows that the excessive insoluble particles are one of the main causes of adverse reaction of transfusion. The particles enter the capillary vessels of the human body, and are easy to cause blockage, granuloma, phlebitis and the like. The insoluble particles are derived from the raw materials of packaging such as infusion bottles and rubber gaskets and pollution in the transportation process, wherein the insoluble particles derived from the raw materials are controllable and predictable in quality inspection and production processes, but the pollution of the rubber gaskets caused by the breakage of the combined cover in the transportation process is uncontrollable, and small breakage which cannot be found or breakage which cannot be seen by naked eyes often occurs.
The combined cover related to the infusion is basically a combined pull ring cover or a combined easy-to-fold cover or a tear film cover, the structure is formed by combining cover bodies (mostly an inner cover body and an outer cover body) and a sealing silicon rubber plug, when the combined cover is used, an opening part of the outer cover body is removed firstly, the silicon rubber plug arranged on the inner cover body is exposed for adding medicine or penetrating a needle for infusion, the penetrating needle of an infusion apparatus is tightly held by the silicon rubber plug to prevent the penetrating needle from separating from an infusion bag, due to the particularity of the infusion, the sealing of the opening part of the outer cover body is not easily damaged before use, and the middle part can be easily pulled open to expose the silicon rubber sealing plug when the infusion apparatus is used.
However, easy lid, pull ring or tear among the prior art and draw the membrane, if make too firmly, can not pull open when can leading to the use or the bag body has destruction, if make too open easily can appear that the gasket receives the pollution, especially insoluble particle etc. that appear under the condition of unknown inject the human body in can cause the medical malpractice more, so combined cover structure among the prior art, the pollution risk increases, complex operation and inconvenient.
Therefore, a combined infusion cap which is free of pollution and easy to operate becomes a technical problem to be solved urgently by the technical personnel in the field.
