Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to an anti - leakage infusion device with a sealing function. Background Art

[0002] In the prior art of using conventional infusion devices, before the start of infusion, it is necessary to separately use a disposable syringe to aspirate normal saline or use a pre - filled syringe to flush or aspirate the vascular access device to evaluate the function of the venous catheter and prevent complications; after the end of infusion, first use a disposable syringe to aspirate normal saline or use a pre - filled syringe to flush the vascular access device to remove the residual liquid medicine and blood in the catheter lumen; after flushing the tube, then perform tube sealing to reduce the risk of catheter occlusion and catheter - related bloodstream infections. At the same time, the liquid medicine is likely to remain in the infusion bag body, which not only causes waste of medicine, but especially when using hazardous drugs, it may also increase the risks of occupational exposure and environmental pollution due to the exposure of the residual liquid medicine. The traditional device has cumbersome operation procedures, excessive use of disposable consumables, lack of effective anti - leakage and sealing mechanisms, cannot fully guarantee the safety and integrity of the entire infusion process, and poses a greater threat to the medication safety of patients, occupational exposure of medical staff, and environmental pollution. Summary of the Invention

[0003] The purpose of the present invention is to provide an anti - leakage infusion device with a sealing function to solve the above problems through optimized design.

[0004] In order to achieve the above technical purpose, the technical solution of this scheme is as follows:

[0005] An anti - leakage infusion device with a sealing function, including a bag body, wherein two partition seals are provided inside the bag body, dividing the space inside the bag body into an upper bag, a middle bag, and a lower bag. A switch handle is provided on the partition strip;

[0006] An input connector is provided on one side of the middle bag, and an output connector is provided at the bottom of the lower bag;

[0007] Grooves are provided at the connection positions of the input connector, output connector and the bag body. The grooves are made of foldable flexible membranes and are integrally formed with the bag body. The bottoms of the input connector and output connector are fixedly and sealingly connected to the flexible membranes at the bottoms of the grooves respectively.

[0008] As an improvement, a sealing strip is provided at the opening position of the groove.

[0009] As an improvement, the sealing strip adopts a peelable seal.

[0010] As an improvement, the upper bag and the lower bag are respectively used to contain 0.9% normal saline, and the middle bag is used to contain a solvent solution.

[0011] The advantages of the present invention are as follows:

[0012] By setting a partition seal and a switch handle, the present invention realizes the orderly dispensing and switching of drugs and normal saline. During the infusion process, the normal saline in the lower bag can be used to flush the tube first, and then the drug in the middle bag can enter the lower bag for infusion by opening the partition seal. Finally, the normal saline in the upper bag is used to flush the bag body to fully mix the residual liquid, ensuring the full utilization of the drug, effectively avoiding drug waste, and improving the safety, economy, and drug utilization rate of infusion treatment. At the same time, it reduces the operation steps of medical staff and the excessive use of disposable consumables.

[0013] The present invention designs grooves at the connection points of the input connector and the output connector with the bag body and is equipped with a peelable sealing strip. After the infusion is completed, the connector is pressed into the groove and sealed with the sealing strip, making the residual liquid in the bag body not easily contact the connector, thus significantly reducing the risks of occupational exposure and environmental pollution caused by the exposure of residual liquid, and having important clinical application value.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. Usually, the components of the embodiments of the present invention described and shown in the accompanying drawings here can be arranged and designed in various different configurations.

[0020] Embodiment 1

[0021] This embodiment discloses an anti - leakage infusion device with a sealing function, which includes a bag body 1. Inside the bag body 1, there are two partition seals 2. The two partition seals 2 divide the space inside the bag body 1 into an upper bag 3, a middle bag 4, and a lower bag 5. A switch handle 6 is provided on the partition seal 2. The upper bag 3 and the lower bag 5 are respectively used to hold 0.9% normal saline; the middle bag is used to hold a solvent solution.

[0022] On one side of the middle bag 4, there is an input connector 7, and at the bottom of the lower bag 5, there is an output connector 8.

[0023] At the connection between the input connector 7, the output connector 8 and the bag body 1, there are grooves 9. The grooves 9 are made of foldable flexible membranes and are integrally formed with the bag body 1. The bottoms of the input connector 7 and the output connector 8 are fixedly and sealedly connected to the flexible membranes at the bottoms of the grooves 9 respectively.

[0024] At the opening position of the groove 9, there is a sealing strip 10. The partition seal 2 and the sealing strip 10 are made of peelable seals.

[0025] The following is an introduction to the usage method of the present invention:

[0026] When the present invention is in use, medical staff need to open the sealing strip at the input connector 7 to expose the input connector 7, and then draw out the solvent solution through the input connector 7 to dilute the drug and inject it into the middle bag 4. Then connect the output connector 8 to the infusion set. The 0.9% normal saline in the lower bag 5 enters the infusion set to flush the tube to determine that the venous catheter is in the blood vessel.

[0027] After the tube flushing is completed, pull the switch handle 6 on the lower partition seal 2 to open the lower partition seal 2. The drug in the middle bag 4 enters the lower bag 5 for infusion. After the infusion is completed, pull the switch handle 6 on the upper partition seal 2. The normal saline in the upper bag 3 is mixed with the residual liquid in the bag body 1 to wash the inner wall of the bag body 1, and at the same time, the drug in the bag body 1 is fully utilized for the patient's infusion.

[0028] After the infusion is over, a routine needle removal is performed. Since the residual liquid of the hazardous drug is exposed to the air, which poses a threat to the health of the dispensing personnel and environmental pollution, it is necessary to seal the input connector 7 and the output connector 8 of the bag body 1 after the infusion is over to avoid the exposure of the drug residual liquid.

[0029] The sealing method is as follows: Invert the bag body 1 so that the main residual liquid in the bag body 1 enters the upper bag 3, and then squeeze the partition seam strip 2 at the upper bag 3 to seal the drug inside the upper bag 3. However, at this time, there may still be some liquid hanging on the wall. At this time, press the input connector 7 and the output connector 8 respectively to the bottom of the groove 9, and then use the sealing strip 10 for further sealing.

[0030] After the input connector 7 and the output connector 8 are pressed into the groove 9, the input connector 7 and the output connector 8 protrude into the interior of the bag body 1, making it difficult for the residual liquid in the bag body 1 to come into contact with the input connector 7 and the output connector 8, thereby reducing the probability of external leakage of the residual liquid. At the same time, through further sealing with the sealing strip 10, the bag body 1 can be effectively sealed to avoid external leakage of the residual liquid in the bag body 1.

[0031] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes, should be covered within the protection scope of the present invention.
