Description

Technical Field

[0001] This utility model belongs to the technical field of infusion products, and particularly relates to a powder-liquid dual-chamber bag. Background Technology

[0002] Veterinary powder-liquid dual-chamber bags are infusion products that solve the storage problem of unstable drugs in solution by separately encapsulating sterile powder and solution in different chambers within the same container. The packaging material used in this method is primarily polyethylene or polypropylene, which have some permeability to oxygen and water vapor and cannot completely block light. To improve the barrier properties of these materials and reduce the impact of oxygen, moisture, and light on the sterile powder, a barrier film is usually added to the outside of the powder-encapsulating membrane. Although this barrier film effectively reduces the risk of degradation of the powder due to environmental factors, it cannot completely prevent all types of degradation or deterioration.

[0003] Therefore, before using a powder-liquid dual-chamber bag, the state of the powder, including its appearance and color, must be carefully inspected before opening the weakly welded isolation strip between the chambers for mixing. Clinical observations have shown that some veterinarians, due to improper operation, may neglect necessary inspection steps and directly squeeze open the isolation strip between the powder and liquid chambers and suspend the bag for infusion without opening the external barrier membrane, thus posing a potential risk to clinical safety. Furthermore, in the current design, the positioning holes on both sides of the bag also serve as suspension holes. Because the suspension points are far from the central axis of the bag, this can cause the bag to tilt, resulting in incomplete drainage of the medication and affecting the therapeutic effect.

[0004] Therefore, in view of the above situation, in order to improve the safety and effectiveness of use, it is urgent to develop a powder-liquid dual-chamber bag to overcome the shortcomings in current practical applications. Utility Model Content

[0017] In order to make the purpose, technical scheme and advantages of the utility model more clear, the following is further described in detail by combining with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model, and are not used to limit the utility model.

[0018] The specific implementation of the utility model is described in detail in the following by combining with specific examples.

[0019] AsFigs. 1-2 As shown, an embodiment of this utility model provides a powder-liquid dual-chamber bag, including a medicine bag 1. The medicine bag 1 has a first chamber bag 2 and a second chamber bag 3 independently disposed inside. The first chamber bag 2 and the second chamber bag 3 are used to hold powder granules and liquid medicine, respectively. A weakly welded isolation strip 4 is provided between the first chamber bag 2 and the second chamber bag 3 to prevent communication between the first chamber bag 2 and the second chamber bag 3. When the second chamber bag 3 is squeezed, the liquid in the second chamber bag 3 breaks through the weakly welded isolation strip 4 and flows into the inner cavity of the first chamber bag 2 and mixes with the powder in the first chamber bag 2. An infusion port 5 is installed on the medicine bag 1 at the end of the second chamber bag 3 away from the first chamber bag 2, and the infusion port 5 is connected to the second chamber bag 3. A hanging hole 6 is provided at the end of the medicine bag 1 away from the infusion port 5. A peelable barrier film 7 is also attached to one side of the medicine bag 1.

[0020] In this embodiment of the invention, when using the powder-liquid dual-chamber bag, the first chamber bag 2 and the second chamber bag 3 are used to hold powdered medicine particles and liquid medicine, respectively. When using the medicine bag, the user first needs to find the opening from the bottom edge of the peelable barrier film 7, and then tear the peelable barrier film 7 from one side of the medicine bag 1 along the bag body. At this time, the user can clearly observe the state of the powder in the inner cavity of the first chamber bag 2. As the user continues to peel the peelable barrier film 7, when the peelable barrier film 7 detaches from one end of the hanging hole 6, the opening of the hanging hole 6 is in the open state. At this time, the user places the medicine bag 1 flat on the table, and then squeezes the second chamber bag 3 by hand, so that the internal pressure of the second chamber bag 3 continues to increase. When the liquid pressure exceeds the threshold, the liquid breaks through the weak welded isolation strip 4 and flows into the inner cavity of the first chamber bag 2 and mixes with the powder in the first chamber bag 2, thereby obtaining the mixed medicine. At this time, the user can suspend the medicine bag on the bracket through the hanging hole 6 for infusion.

[0021] In a preferred embodiment of the present invention, the medicine bag 1 is provided with a non-peelable barrier film on the side away from the peelable barrier film 7, and the non-peelable barrier film does not cover the hanging hole 6.

[0022] In a preferred embodiment of this utility model, the edges of the first cavity bag 2 and the second cavity bag 3 are sealed by solid welding to ensure the airtightness of the medicine bag 1.

[0023] like Fig. 2 As shown, in a preferred embodiment of the present invention, the peelable barrier film 7 is attached to and covers the first cavity bag 2, the weak weld isolation strip 4 and the hanging hole 6, ensuring that the peelable barrier film 7 forms a completely light-blocking surface on one side of the first cavity bag 2.

[0024] Preferably, the peelable barrier film 7 is provided with a sealing opening 8 at one end near the weak welding isolation strip 4, and the sealing opening 8 is provided with a gap between it and the medicine bag 1. The other end of the peelable barrier film 7 is provided with a blocking sheet 9, and the blocking sheet 9 is provided on the side near the hanging hole 6.

[0025] During application, a gap is left between the sealing opening 8 and the outer surface of the medicine bag 1, so that when the user peels off the peelable barrier film 7, he can push up one end of the sealing opening 8 through the gap on one side of the sealing opening 8 and pull the sealing opening 8 to detach the peelable barrier film 7 from the surface of the medicine bag 1; the blocking sheet 9 is attached to one side of the hanging hole 6 so that when the peelable barrier film 7 is in the attached state, the hanging hole 6 is in the blocked state, preventing the user from directly administering the infusion without checking the mixing state of the powder and the medicine.

[0026] It is understandable that, such as Fig. 2 As shown, the medicine bag 1 has a first surface a, and the peelable barrier film 7 has a second surface b. The second surface b is attached to the first surface a and covers one side of the hanging hole 6. The hanging hole 6 is located in the middle of the first surface a. The first surface a and the second surface b are in close contact during use, and the second surface b is difficult to tear directly from the first surface a side when in contact. This prevents the user from directly peeling off the barrier film 7 from the first surface a and then hanging the medicine bag directly through the hanging hole 6. The hanging hole 6 is located in the middle of the first surface a, so that the medicine inside the medicine bag 1 can be smoothly discharged during the hanging process, avoiding the retention of residual medicine.

[0027] The present invention provides a powder-liquid dual-chamber bag in the above embodiments. By providing a peelable barrier film 7 on one side of the medicine bag 1, and providing a blocking piece 9 at one end of the peelable barrier film 7 to block the hanging hole 6, the user can be forced to inspect the medicine powder in the medicine bag 1 before infusion, thus avoiding potential safety hazards.

[0028] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0029] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
