Safe, convenient and fast liquid preparation and residue-free high-capacity injection containerTechnical Field
The invention belongs to the field of medical packaging containers, and particularly relates to a safe, convenient and fast liquid preparation and residue-free high-capacity injection container.
Background
When clinical medicines are used, powder injection medicines or small-volume injection and large-volume injection bottle liquid are mixed and then injected for use. In particular, when the preparation to be prepared is an injection sterile powder, a method commonly used in the prior art is to inject a certain amount of liquid into a powder injection bottle by using a syringe, dissolve and dilute the liquid, then withdraw the mixed liquid in the powder injection bottle by using the syringe, and finally inject the mixed liquid into a large-capacity injection bottle. The traditional method is complex in operation steps, cross infection or environmental pollution is easily caused in a complex operation process, the workload of nurses is increased, the risk of aseptic operation is increased, and great hidden danger is brought to medication safety. In addition, when the existing injection container is used for transfusion to the end, part of residual liquid at the bottle mouth often cannot flow out, and when the medicine is a special medicine or accurate administration is required, the residual liquid often influences the treatment effect of a patient, so that precious medicine is wasted and the administration dosage is deviated.
