Description

An infusion bag with a dispensing device

technical field

The utility model relates to a medical device, in particular to an infusion bag with a dispensing device.

Background technique

Intravenous infusion is the most widely used method of drug administration in clinical practice. When adding drugs to intravenous infusion, most drugs need to be diluted and re-constituted. Therefore, dispensing medicines has become an important part of the work of nurses or pharmacists in pharmacy dispensing centers An important part of drug treatment effect.

At present, in clinical practice, the operator generally uses a disposable 20ml dispensing syringe to extract a certain amount of liquid from solid drug diluent, sodium chloride injection, glucose injection and other solvents into the solid drug bottle for full dissolution. Afterwards, the solute is injected into infusion bags such as sodium chloride injection or glucose injection, or the solute such as aqueous injection is directly extracted and injected into the infusion bag to prepare a finished infusion. During the process of preparing the liquid medicine, it is necessary to puncture the stopper of the medicine bottle or the stopper of the infusion bag multiple times and repeatedly pull the stopcock of the dispensing syringe, which will easily cause insoluble particles and cork debris to enter the liquid bottle. The rubber stopper of the infusion bag is prone to leaks after repeated punctures, which can lead to extravasation of fluid during the infusion process. When using a syringe to dispense medicine, especially when adding multiple medicines, it is necessary to repeatedly aspirate, puncture the stopper, or load and unload the needle. It is easy to cause redness, swelling and fatigue of the thenar muscles in the palm of the operator's hand and finger joints, and it is time-consuming and labor-intensive, increasing the workload.

Technical problems to be solved: 1. The number of punctures of the bottle stopper of the medicine bottle and the rubber stopper of the infusion bag should be reduced, the particle content in the solution should be reduced, and the airtightness of the rubber stopper of the infusion bag should be guaranteed. 2. Avoid the pollution caused by repeated aspiration, loading and unloading of the syringe. 3. The operation should be simple and easy to reduce operator fatigue and save time and effort. 4. One bag and one independent dispensing device shall ensure the safe operation of dispensing.
