Description

A new type of liquid sub-packaging bag and infusion set

technical field

The utility model relates to the field of medical equipment, in particular to a novel liquid packaging bag and an infusion set.

Background technique

The currently clinically used bag type infusion set consists of a liquid sub-bag, an upper transfusion tube, a Murphy's dropper, a lower transfusion tube, a venipuncture needle and a regulator provided on the transfusion tube from top to bottom. In clinical intravenous infusion work, certain drugs must be infused several times a day in small amounts to maintain effective blood drug concentrations. Especially in pediatrics, when liquid is used routinely, it is necessary to dissolve the liquid into the drug after repacking. Therefore, it is necessary to add a specific amount of liquid medicament to the liquid distribution bag at a specific time, and a drug feeding tube is usually arranged on the liquid distribution bag. For example, the Chinese patent with publication number CN202859777U discloses a disposable bag type infusion set. The dosing tube and the infusion tube are set together on the liquid inlet, and connected with the infusion tube in parallel, so that there is no need to manually shake the liquid sub-bag to mix the medicine evenly after dosing, which simplifies the operation, but the dosing tube is independent from the infusion The tubular structure of the tube has a certain degree of flexibility. When adding medicine, it is necessary to pierce the tubular structure with a needle and then push the syringe piston to inject the medicine. In addition, because the bag body wall of the liquid sub-bag is subjected to atmospheric pressure, it is very easy to stick together, and the added medicament can not flow rapidly to the bottom of the bag, which is not easy to quickly observe the volume of the added medicament.
