Abstract

The invention discloses a double-needle device for drug dispensing, and relates to the technical field of medical apparatus. The double-needle device comprises an injection needle body (1), a ventilating needle body (2), a filter screen (3) and a connecting tape (4), wherein the injection needle body (1) and the ventilating needle body (2) are connected by virtue of the connecting tape (4); and the filter screen (3) is arranged on the ventilating needle body (2). The double-needle device disclosed by the invention is simple in structure and convenient to operate, and the double-needle device can facilitate doctors to operate; and meanwhile, the double-needle device can achieve sterile operation, so that drug contamination is avoided.

Description

Technical field: [0001] The invention relates to the technical field of medical devices, in particular to a double needle for drug preparation. Background technique: [0002] In the process of drug preparation, especially powder preparations, it is necessary to add the preparation solution or saline to fully dissolve the drug solution before the drug is prepared, but the drug powder maintains a negative pressure state during the filling process. If you want to extract the liquid, you need to enter the same amount of gas to become Positive pressure state. In the past, when nurses dispensed medicines, drug spillage often occurred (occupational injuries caused by chemotherapeutic drugs and antibiotics) and normal aseptic operation was not possible (due to insufficient gas volume, the needle needs to be pulled out to suck the gas and then inserted into the ampoule. This operation is easy to bring into the air. A large number of bacteria will cause drug pollution and affect the ...
