However, for oncology patients, infusions must be administered sequentially to avoid incompatibilities. Currently, various medications are packaged in separate bags and hung on an IV stand. This can easily lead to medication errors when nurses change fluids. Therefore, developing a novel fluid rehydration bag structure to overcome these issues present in existing technologies is a topic for further research by those skilled in the art. Utility Model Content

[0003] The purpose of the utility model is to provide a multifunctional fluid infusion bag, which can clarify the order of drug administration when performing fluid infusion on patients in the oncology department to effectively avoid incompatibility taboos, ensure the accuracy of the drug administration sequence and the safety of the patient's medication.

[0004] The technical solution provided by the utility model is a multifunctional fluid infusion bag, which includes:

[0005] A fluid rehydration assembly, comprising a plurality of fluid rehydration bags arranged in sequence along a vertical direction, with adjacent fluid rehydration bags connected via fluid conduits, each of the fluid conduits being provided with a rotary switch valve for regulating the conduction / blocking of the fluid conduits;

[0006] A Murphys drip irrigation system, wherein an input end of the Murphys drip irrigation system is electrically connected to the lowest rehydration bag among the plurality of rehydration bags;

[0007] An infusion strap, the head end of which is conductively connected to the output end of the Murphys drip irrigation.

[0008] This technical solution involves sequentially dispensing the corresponding medication into each rehydration bag in the rehydration assembly according to a pre-set dosing sequence, with each rotary valve initially closed. Infusion is initiated via an infusion strap. Whenever a rehydration bag is depleted, the rotary valve opens the next rehydration bag above it, continuing until all rehydration bags in the rehydration assembly are depleted sequentially from bottom to top. During this infusion process, Murphys drip irrigation prevents backflow and filters impurities in the rehydration solution.

[0009] Preferably, the fluid infusion assembly further comprises a flexible flat bottom plate, and the plurality of fluid infusion bags are respectively mounted on a side surface of the flexible flat bottom plate.

[0010] By adopting this technical solution: a plurality of fluid infusion bags are arranged to be fixed on the flexible flat bottom plate, the connection relationship between the fluid infusion bags is increased, and the conductive connection between adjacent fluid infusion bags is made more stable.

[0011] Preferably, a hanging ring is provided on the top of the flexible planar bottom plate.

[0012] By adopting this technical solution, the flexible plane bottom plate is integrally suspended on the infusion stand by using the hanging ring during the infusion process.

[0013] Preferably, a Velcro surface is provided on one side surface of the flexible flat bottom plate, and a Velcro quill surface is provided on the bag body of each of the plurality of fluid infusion bags.

[0014] By adopting this technical solution: each fluid rehydration bag is fixed to one side of the flexible flat bottom plate through a Velcro structure, which facilitates the convenient disassembly and assembly of the fluid rehydration bag to the flexible flat bottom plate, and realizes the reuse of the flexible flat bottom plate.

[0015] Preferably, each of the plurality of fluid infusion bags is provided with a dispensing opening on its bag body.

[0016] By adopting this technical solution: in practice, the corresponding medicine solution is prepared in sequence on each rehydration bag through each preparation port.

[0017] Preferably, the bag body of each of the several fluid infusion bags has a flat centrally symmetrical structure and includes a horizontal upper part and a conical lower part; the two ends of the fluid catheter are respectively connected to the horizontal upper part of one of the fluid infusion bags and the conical lower part of another of the fluid infusion bags; and the dispensing port is arranged at the horizontal upper part.

[0018] This technical solution, by configuring the rehydration bag as a flat structure, facilitates the injection of a sufficient amount of liquid medicine into a single bag while simultaneously reducing the overall design height of the flexible flat base plate. Accordingly, the tapered lower portion facilitates the outflow of liquid medicine from the flat structure of the rehydration bag. Positioning the dispensing port at the horizontal upper portion prevents liquid medicine from overflowing the rehydration bag through the dispensing port.

[0019] Preferably, a fluorouracil chemotherapy pump is provided at the tail end of the infusion strap.

[0020] By adopting this technical solution: using a fluorouracil chemotherapy pump to achieve infusion control based on the patient's body temperature.

[0021] Compared with the prior art, the utility model has the following advantages:

[0022] First, the utility model can clarify the order of medication when performing fluid infusion on patients in the oncology department to effectively avoid incompatibility, ensure the accuracy of the medication order and the safety of the patients' medication.

[0023] Secondly, the utility model can realize infusion control according to the patient's body temperature.

[0024] Finally, the utility model has a simple structure and a simple operation process, and is easy for medical staff to prepare manually and use clinically. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Example 1, please refer to Figure 1-2 :

[0031] A multifunctional fluid rehydration bag 110 includes a fluid rehydration component, a Murphys drip irrigation device 200, and an infusion strap 300.

[0032] Among them, the fluid infusion component includes seven fluid infusion bags 110 and a flexible flat bottom plate 120. A hanging ring 121 is provided on the top of the flexible flat bottom plate 120. The seven fluid infusion bags 110 are respectively fixedly mounted on the flexible flat bottom plate 120 and arranged in sequence along the vertical direction. And the adjacent fluid infusion bags 110 are connected by fluid guide tubes 130. Specifically: the bag body of each of the several fluid infusion bags 110 is a flat centrally symmetrical structure, and includes a horizontal upper part and a conical lower part; the two ends of the fluid guide tube 130 are respectively connected to the horizontal upper part of the fluid infusion bag 110 located on the lower side and the conical lower part of the fluid infusion bag 110 located on the upper side of the two adjacent fluid infusion bags 110. Each fluid guide tube 130 is respectively provided with a rotary switch valve 140, and the rotary switch valve 140 is used to adjust the conduction / blocking of the fluid guide tube 130;

[0033] Each of the multiple rehydration bags 110 is provided with a dispensing port 150 at its upper horizontal portion. The input end of the Murphys drip irrigation system 200 is electrically connected to the lowest of the multiple rehydration bags 110. The head end of the infusion strap 300 is electrically connected to the output end of the Murphys drip irrigation system 200. A fluorouracil chemotherapy pump 310 is provided at the tail end of the infusion strap 300.

[0034] In clinical practice, taking oncology as an example, there are incompatibility taboos for daily medications for cancer patients as shown in Table 1 below.

[0035]

[0036] Table 1

[0037] In practice, the process works as follows:

[0038] Based on the high-energy nutrition (TPN) bag, the total capacity of seven rehydration bags 110 is set to 4000ml, and each of the seven rehydration bags 110 is filled with seven insoluble liquids. During the infusion, the nurse opens the rotary switch valves 140 in sequence from bottom to top, and the liquids in each rehydration bag 110 are infused into the patient in order from bottom to top. The bag material of each rehydration bag 110 is configured to effectively preserve the liquid for 24 hours and is biodegradable, significantly reducing environmental pollution. During the infusion process, the fluorouracil chemotherapy pump 310 utilizes the principle of human body temperature control, eliminating the need for manual infusion by the nurse. During the infusion process, the Murphys drip irrigation system 200 is used to prevent backflow and filter impurities in the infusion solution. The advantages of this solution include: on the one hand, it facilitates the infusion of chemotherapy patients undergoing intubation and can prevent incompatibilities among the patient's daily medications. At the same time, the nurses are less likely to plug the fluid infusion bag 110 and the infusion strap 300, thereby greatly reducing the risk of needle stick injuries to the nurses.
