Description

Safe transfusion double-chamber bag

Technical Field

The utility model relates to the field of medical devices, in particular to a safe transfusion double-chamber bag.

Background

When the existing flexible package transfusion product is produced, only liquid is filled, and when the product is used as a basic liquid for treating diseases and applied to the body of a patient, antibacterial powder is often required to be added, after the product is mixed, the product is infused into the human body, as shown in figure 1, the transfusion bag is a single body, different liquid medicines (such as sodium chloride injection) are filled in the liquid chamber 1 according to different specifications, and the powder bottle 15 is filled with therapeutic antibiotic powder; when in clinical use, the injector 16 is used for taking out about 5-10 ml of liquid in the infusion bag through the liquid filling port 7, then the liquid is injected into the powder bottle for dissolution, and then the liquid is led into the infusion bag through the injector 16 after dissolution, the operation is repeated for 2-3 times, the liquid medicine can be mixed, and the infusion hanging hole 10 is hung on the infusion support for infusing to a human body after the liquid medicine is mixed. The existing mode is used for preparing the liquid medicine, an independent preparation center is needed for completing the preparation, the syringe 16 is punctured between two different liquid medicines in the preparation process, the problem that the rubber plug at the medicine adding port 17 is desquamated is easily caused, the holding quality of products such as foreign matters or particles can be influenced, and the same syringe 16 is used for operation, so that a certain risk of cross contamination is also caused. There may be operational risks, and sometimes medical staff may configure not only one infusion bag, but also two or more infusion bags at the same time, which may cause a risk of adding wrong liquid medicine.

Aiming at the above existing different risk problems, a second improvement scheme appears in the prior art, specifically as shown in fig. 2, and on the basis of the scheme, the improvement scheme completes the integration of two kinds of liquid medicine in a factory through industrialized integration, and the working principle is as follows: the powder-liquid infusion bag is produced by a bag making machine, the welding of the first weak welding rod 4 is finished, the powder-liquid infusion bag is sent to a filling part to be finished after the welding, liquid is filled into the liquid chamber 1 through an infusion interface, the combined cover 12 is welded after the liquid is filled, the product of the powder-liquid infusion bag is finished and is sent to sterilization, powder with required proportion is filled into the powder chamber 2 according to the technological requirement after the sterilization, and then the powder is welded and sealed.

The improved scheme has the advantages that the product is integrated into a factory to be uniformly produced, each environment is controlled by the factory, and pollution risks generated in the use process of a user can be avoided; the liquid and the powder are reasonably distributed to two areas, are completely separated and distinguished, and can be opened only when being used again; the mode is convenient to use, only the aluminum film 9 is required to be torn at an easy tearing port, whether the powder has quality problems or not is observed, if the powder has the quality problems, the liquid cavity is extruded by hands, the first weak welding rod 4 can be opened after the powder cavity is extruded forcefully, the liquid enters the powder cavity, the liquid can be contacted with the powder, and the powder can be used after the powder is mixed and is shaken back and forth for about seconds. The liquid medicine is mixed and then used through the transfusion mouth part; the bag folding area 14 can enable the manufactured bag to be folded, and further save the packaging space.

However, the powder chamber 2 has the following defects that the space is larger, the saving of packing materials is not facilitated, and the production cost is increased; the tail arc of the powder chamber 2 is filtered more gently, and when powder and liquid are mixed, certain residues exist, so that the mixing uniformity is affected; the two layers outside the infusion bag body are welded with the aluminum film 9, the welding requirement of the aluminum film 9 is high, secondary damage is easily caused to the welded infusion bag, and powder leakage risk can be caused; the use is not quick, the easy-to-tear film is required to be torn off, and the powder can be used after being checked; it also appears that the operator would squeeze out to mix the liquid medicine without tearing the aluminum film 9; the used combined cover is also required to be heated to a proper melting point with the connector after being filled, and then the combined cover is welded, so that the problems of black edges of the cover and wire drawing of plastic in the process can be solved; the combined cover containing the rubber plug is used, and the risk of introducing medicine is also presented; because the surface of the powder cavity is covered with the aluminum film 9, the liquid can be directly used up under the condition that an operator does not open the first weak welding rod 4 to mix the powder, so that the curative effect is greatly reduced, and the like. Among the above drawbacks, particularly with respect to safety performance, is a problem of great concern to the public patients.

In view of this, the present application has been made.
