Description

Technical Field

[0001] This utility model relates to the technical field of infusion bags, and more specifically, to a multi-chamber parenteral nutrition bag for preventing infusion errors. Background Technology

[0002] Parenteral nutrition multi-chamber bags contain different medications in different chambers, which are separated by a welded section. During use, the medications in each chamber are mixed by squeezing, and then infused. The method of use is simple, and parenteral nutrition multi-chamber bags are widely used in clinical treatment in hospitals.

[0003] During use, the medication in each chamber needs to be fully mixed before infusion. However, since the poorly welded part is usually a strip structure, it may not be fully squeezed open before infusion. This means that the medication may not be fully mixed during infusion, which may have a certain adverse effect on the patient's treatment. Therefore, an infusion bag that can effectively prevent infusion errors can be designed. Utility Model Content

[0004] The purpose of this invention is to provide a multi-chamber parenteral nutrition bag that prevents infusion errors, which can effectively ensure that the medication in the bag is fully mixed before infusion.

[0005] This utility model is achieved through the following technical solution: The multi-cavity parenteral nutrition bag of this utility model for preventing infusion errors includes a square bag body, multiple strip-shaped first slit welds disposed within the bag body, an infusion tube disposed on the bag body, and an L-shaped second slit weld disposed within the bag body; the multiple first slit welds divide the interior of the bag body into multiple drug solution cavities, and the two ends of the second slit welds are respectively connected to the adjacent side walls of the bag body, and the second slit welds and the side walls of the bag body enclose a cavity; the infusion tube communicates with the cavity.

[0006] Furthermore, the heat-sealing strength of the first malformed weld is lower than that of the second malformed weld.

[0007] Furthermore, the heat-sealing strength of the first incomplete weld is 8-12 N / 15 mm; the heat-sealing strength of the second incomplete weld is 13-15 N / 15 mm.

[0008] Furthermore, the infusion tube is positioned near the corner of the bag.

[0009] Furthermore, the end of the bag body away from the infusion tube is provided with a tail hole and a hanging hole; the tail hole is located in the middle of the bag body, and the line connecting the hanging hole and the infusion tube passes through the center of the bag body.

[0010] Furthermore, the infusion tube includes a first tube body communicating with the cavity, a first rubber stopper disposed at the end of the first tube body away from the bag body, and a first cap disposed on the first rubber stopper.

[0011] Furthermore, the infusion tube also includes a valve plate disposed on the first cover.

[0012] Furthermore, the bag body is connected to multiple sealing tubes, and one of the sealing tubes is connected to one of the liquid medicine chambers.

[0013] Furthermore, the sealing tube includes a second tube body, a second rubber stopper disposed on the second tube body, and a second cap disposed on the second rubber stopper.

[0014] The technical solution of this utility model has at least the following advantages and beneficial effects: The multi-chamber parenteral nutrition bag of this utility model, which prevents infusion errors, stores different medications in different medication chambers. When infusion is needed, the bag is first squeezed to open the first loose weld, allowing the different medications to mix thoroughly. Then, the bag is squeezed further to open the second loose weld, allowing the medication to be discharged through the infusion tubing. Finally, the corresponding tubing is inserted into the infusion tubing to begin the infusion operation. Throughout the process, it effectively ensures that all medications are thoroughly mixed before being discharged through the infusion tubing, effectively guaranteeing the uniformity of the medication mixture. Furthermore, compared to traditional infusion bags, the entire process is simple and efficient, without any unnecessary or complicated steps. Attached Figure Description

Detailed Implementation

[0017] Example

[0018] The following description, in conjunction with specific embodiments, further illustrates the point, as shown in the appendix. Figure 1As shown, the multi-chamber parenteral nutrition bag for preventing infusion errors in this embodiment includes a square bag body 11, multiple strip-shaped first ventilated sections 12 disposed within the bag body 11, an infusion tube 20 disposed on the bag body 11, and an L-shaped second ventilated section 13 disposed within the bag body 11. The multiple first ventilated sections 12 divide the interior of the bag body 11 into multiple drug solution chambers 14. The two ends of the second ventilated sections 13 are respectively connected to the adjacent side walls of the bag body 11, and the second ventilated sections 13 and the side walls of the bag body 11 enclose a cavity 15. The infusion tube 20 communicates with the cavity 15. Specifically, in use, different medications are stored in different drug solution chambers 14. When infusion is needed, the bag body 11 is first squeezed to open the first ventilated sections 12, allowing the different medications to mix thoroughly. Then, the bag body 11 is squeezed further to open the second ventilated sections 13, allowing the medication to be discharged through the infusion tube 20. Finally, the corresponding tubing is inserted into the infusion tube 20 to begin the infusion operation. Throughout the process, it effectively ensures that all medications are thoroughly mixed before being discharged through the infusion tube 20, thus guaranteeing the uniformity of the medication mixture. Compared to traditional infusion bags, the process is simple and efficient with no extra steps.

[0019] In this embodiment, the heat-sealing strength of the first incomplete weld 12 is lower than that of the second incomplete weld 13. The heat-sealing strength of the first incomplete weld 12 is 8-12 N / 15 mm; the heat-sealing strength of the second incomplete weld 13 is 13-15 N / 15 mm. Specifically, when welding the first incomplete weld 12 and the second incomplete weld 13, the heat-sealing strength of the first incomplete weld 12 can be set to be lower in advance. In this way, when extruding the bag body 11, it is not necessary to deliberately break the first incomplete weld 12 first. During the extrusion process, because the heat-sealing strength of the first incomplete weld 12 is lower, it will break first, allowing the medicine to mix first, and then the second incomplete weld 13 will break. This makes the operation simpler and has a higher error tolerance.

[0020] In this embodiment, the infusion tube 20 is positioned near the corner of the bag body 11. The end of the bag body 11 furthest from the infusion tube 20 has a tail hole 16 and a hanging hole 17; the tail hole 16 is located in the middle of the bag body 11, and the line connecting the hanging hole 17 and the infusion tube 20 passes through the center of the bag body 11. Specifically, when suspending the bag body 11, it can be suspended through the hanging hole 17, and the infusion tube 20 will be at the bottom of the bag body 11, allowing the medication to flow out of the bag body 11 more efficiently.

[0021] In this embodiment, the infusion tubing 20 includes a first tube body 21 communicating with the cavity 15, a first rubber stopper 22 disposed at the end of the first tube body 21 away from the bag body 11, and a first cap 23 disposed on the first rubber stopper 22. The infusion tubing 20 also includes a valve plate 24 disposed on the first cap 23. Specifically, during infusion, the first cap 23 can be unscrewed by pinching the valve plate 24, and then the infusion needle can be passed through the first rubber stopper 22.

[0022] In this embodiment, the bag body 11 is connected to multiple sealing tubes 30, and each sealing tube 30 is connected to a medicine liquid chamber 14. Each sealing tube 30 includes a second tube body 31, a second rubber stopper 32 disposed on the second tube body 31, and a second cap 33 disposed on the second rubber stopper 32. Specifically, the sealing tube 30 is mainly used to inject medicine liquid into the medicine liquid chamber 14 during production. After the injection is completed, the second rubber stopper 32 and the second cap 33 are used to seal the second tube body 31.

[0023] In summary, the multi-chamber parenteral nutrition bag of this embodiment, designed to prevent infusion errors, stores different medications in separate medication chambers 14. When infusion is needed, the bag body 11 is first squeezed to open the first loose weld 12, allowing the different medications to mix thoroughly. Then, squeezing continues to open the second loose weld 13, allowing the medication to be discharged through the infusion tube 20. Finally, the appropriate tubing is inserted into the infusion tube 20 to begin the infusion procedure. This process effectively ensures that all medications are thoroughly mixed before being discharged through the infusion tube 20, guaranteeing uniformity of the medication mixture. Compared to traditional infusion bags, this process is simpler and more efficient, without requiring additional complex steps.

[0024] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
