[0002] An infusion bag is a medical device or pharmaceutical packaging bag, generally made of polymer materials, used to store or store liquid medicine or nutrient solution after injection, and is introduced into the body through an infusion set and intravenous device.

[0003] Existing infusion bags typically have simple sealing devices at the bag opening, such as rubber stoppers and plastic caps. However, in actual use, infusion bags may be subjected to external forces such as squeezing and collisions during transportation, storage, or operation, which can easily lead to incomplete sealing at the bag opening and leakage. Leakage not only wastes medication but may also pollute the surrounding environment and even affect the patient's treatment safety.

[0004] Therefore, a leak-proof structure for infusion bags is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, a simple sealing device, such as a rubber stopper and a plastic cap, is usually set at the bag opening. However, in actual use, the infusion bag may be subjected to external forces such as squeezing and collision during transportation, storage or operation, which can easily lead to poor sealing at the bag opening and leakage. Leakage not only wastes medicine, but may also pollute the surrounding environment and even affect the patient's treatment safety.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The infusion bag anti-leakage structure of this utility model includes an infusion bag body, a sealing suspension assembly is provided at the top of the infusion bag body, an outer protective assembly is connected to the outer wall of the infusion bag body, and a sealing connection assembly is installed at the bottom of the infusion bag body; the sealing suspension assembly includes a sealing screw, a sealing gasket is glued to the bottom of the sealing screw, a connecting seat is rotatably connected to the top of the sealing screw, and a suspension ring is rotatably connected to the top of the connecting seat.

[0007] Preferably, the suspension ring and the connecting seat form a rotating structure, and the connecting seat and the sealing screw form a rotating structure, and the sealing screw forms a sealing structure with the infusion bag body through the sealing gasket.

[0008] Preferably, the outer protective component includes an inner layer, a reinforcing layer is bonded to the outer wall of the inner layer, a protective layer is bonded to the outer wall of the reinforcing layer, and a protrusion is integrally provided on the outer wall of the protective layer.

[0009] Preferably, the protrusions are evenly spaced about the outer wall of the protective layer, and the material of the protective layer and the protrusions is silicone.

[0010] Preferably, the reinforcing layer is made of hard plastic, the inner layer is made of flexible sponge, and the inner layer is bonded to the infusion bag body with adhesive, and the infusion bag body is made of medical-grade plastic.

[0011] Preferably, the sealing connection assembly includes a connecting pipe, a fixed seat is fixedly connected to the bottom of the connecting pipe, and a rotating seat is rotatably connected inside the fixed seat. A threaded joint is fixedly connected to the bottom of the rotating seat, and an infusion tube is threadedly connected to the bottom of the threaded joint.

[0012] Preferably, the threaded connector and the infusion tube form a threaded sealing structure, and the threaded connector forms a rotating structure with the fixed seat through the rotating seat.

[0013] The advantages of this utility model are:

[0014] 1. This utility model is equipped with a sealing and suspension assembly. The sealing screw can protect the drug delivery port, effectively preventing external impurities such as dust and microorganisms from entering the infusion bag and avoiding contamination of the infusion fluid. At the same time, a sealing gasket is provided at the connection, which can greatly reduce the possibility of fluid leakage from the drug delivery port, thereby reducing drug waste and preventing pollution to the surrounding environment.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] Example 1

[0026] like Figures 1 to 3As shown, an infusion bag leak-proof structure includes an infusion bag body 1, a sealing and suspension assembly 2 at the top of the infusion bag body 1, an outer protective assembly 3 connected to the outer wall of the infusion bag body 1, and a sealing connection assembly 4 installed at the bottom of the infusion bag body 1. The sealing and suspension assembly 2 includes a sealing screw 201, a sealing gasket 202, a connecting seat 203, and a suspension ring 204. The sealing and suspension assembly 2 ensures that the infusion bag's drug delivery port is sealed to prevent leakage and contamination through the sealing screw 201 and the sealing gasket 202. The suspension ring 204 facilitates the hanging of the infusion bag. The suspension ring 204 and the connecting seat 203 form a rotating structure, and the connecting seat 203 and the connecting seat 203 form a rotating structure. The sealing screw 201 forms a rotating structure, and the sealing screw 201 and the infusion bag body 1 form a sealing structure through the sealing gasket 202. The sealing screw 201 can protect the drug injection port, effectively preventing external impurities such as dust and microorganisms from entering the infusion bag and avoiding contamination of the infusion fluid. At the same time, the sealing gasket 202 is set at the connection, which can greatly reduce the possibility of liquid leakage from the drug injection port, thereby reducing drug waste and preventing pollution to the surrounding environment. In addition, a hanging ring 204 is set at the top of the sealing screw 201, which allows medical staff to easily hang the infusion bag on the infusion stand.

[0027] like Figure 1 and Figure 5 As shown, an infusion bag leak-proof structure includes an outer protective component 3, comprising an inner layer 301, a reinforcing layer 302, a protective layer 303, and protrusions 304. The flexible sponge inner layer 301, the hard plastic reinforcing layer 302, the silicone protective layer 303, and the protrusions 304 of the outer protective component 3 respectively serve to buffer external forces, enhance deformation resistance, and further buffer, protecting the infusion bag body 1. The protrusions 304 are evenly spaced relative to the outer wall of the protective layer 303. The protective layer 303 and the protrusions 304 are made of silicone, the reinforcing layer 302 is made of hard plastic, the inner layer 301 is made of flexible sponge, and the inner layer 301 is bonded to the infusion bag body 1. The infusion bag body 1 is made of medical-grade plastic. An outer protective component 3 is connected to the outer wall of the infusion bag body 1. The outer protective component 3 is provided with an inner layer 301, a reinforcing layer 302, a protective layer 303, and protrusions 304. The inner layer 301 is made of flexible sponge, which has good elasticity and cushioning performance. When the infusion bag is subjected to external collisions, squeezing, or drops, the flexible sponge can effectively absorb and disperse the impact force, reducing direct damage to the infusion bag body 1. The reinforcing layer 302 is made of hard plastic, which can enhance the overall deformation resistance of the infusion bag body 1 and prevent the infusion bag body 1 from being excessively twisted or bent when subjected to large external forces. The protective layer 303 and the protrusions 304 are made of silicone. These protrusions 304 can further play a cushioning role when the infusion bag body 1 comes into contact with other objects.

[0028] like Figure 1 , Figure 2 and Figure 4 As shown, an infusion bag leak-proof structure includes a sealing connection component 4, comprising a connecting pipe 401, a fixed base 402, a rotating base 403, a threaded connector 404, and an infusion tube 405. The sealing connection component 4 uses the rotating base 403 to connect the infusion tube 405 and the connecting pipe 401. Compared with traditional connection methods, this can save medical staff's operation time. The threaded connector 404 and the infusion tube 405 form a threaded sealing structure, and the threaded connector 404 forms a rotating structure with the fixed base 402 through the rotating base 403. By rotating the rotating base 403, the infusion tube 405 and the connecting pipe 401 can be connected. Compared with some traditional connection methods, such as those that require plugging and unplugging, tightening multiple parts, or using special connectors, this can greatly save medical staff's operation time.

[0029] Working principle: First, an outer protective component 3 is connected to the outer wall of the infusion bag 1. The outer protective component 3 is provided with an inner layer 301, a reinforcing layer 302, a protective layer 303, and a protrusion 304. The inner layer 301 is made of flexible sponge, which has good elasticity and cushioning performance. When the infusion bag 1 is subjected to external collisions, squeezing, or drops, the flexible sponge can effectively absorb and disperse the impact force, reducing direct damage to the infusion bag 1. It also prevents the infusion bag 1 from breaking or being damaged, thereby ensuring the integrity and sterility of the liquid inside the infusion bag 1, avoiding drug leakage and waste, and reducing the risk of patients being unable to use the infusion bag due to damage to the infusion bag 1. The risks associated with normal infusion are mitigated by the fact that the reinforcing layer 302 is made of hard plastic, which provides additional structural support and protection for the infusion bag. The hard plastic enhances the overall resistance to deformation of the infusion bag body 1. When the infusion bag body 1 is squeezed in a narrow space or compressed by other heavy objects, the hard plastic reinforcing layer 302 can maintain the basic shape of the infusion bag body 1. The protective layer 303 and the protrusions 304 are made of silicone. These protrusions 304 can further buffer the infusion bag body 1 when it comes into contact with other objects. In particular, when the infusion bag body 1 comes into contact with sharp or hard objects, the protrusions 304 can make contact with and disperse the pressure first, reducing the local impact force on the bag body and reducing the possibility of the bag body being punctured or scratched.

[0030] Next, the medication is injected through the drug inlet at the top of the infusion bag 1. Then, the sealing screw 201 can be rotated to protect the drug inlet. A sealing gasket 202 is provided at the connection of the sealing screw 201. The sealing gasket 202 can greatly reduce the possibility of liquid leakage from the drug inlet, thereby preventing drug leakage. The infusion bag 1 can be suspended on the infusion stand by the suspension ring 204. Since the connecting seat 203 can rotate within the sealing screw 201, the infusion bag 1 can rotate, allowing medical staff to easily view the label information on the infusion bag when making rounds in the ward or adjusting the infusion device for the patient. Finally, the rotating seat 403 can be rotated. At this time, the rotating seat 403 will rotate through the fixed seat 402, and the threaded connector 404 will rotate. The threaded connector 404 will connect the infusion tube 405 to the connecting tube 401.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
