Description

Technical Field

[0001] The present invention belongs to the technical field of infusion products, and particularly relates to a powder-liquid double-chamber bag. Background Art

[0002] The veterinary powder-liquid double-chamber bag is an infusion product. By separately encapsulating sterile powder and dissolving solution in different chambers of the same container, it solves the storage problem of unstable drugs in solution state. The film materials used in this packaging method are mainly polyethylene or polypropylene, which have certain permeability to oxygen and water vapor and cannot completely block light. To improve the barrier performance of these film materials and reduce the influence of oxygen, moisture and light on the sterile powder, a barrier film is usually added outside the film material for encapsulating the powder. Although this barrier film can effectively reduce the degradation risk of the powder caused by environmental factors, it cannot completely prevent all types of degradation or deterioration.

[0003] Therefore, before using the powder-liquid double-chamber bag, it is necessary to carefully check the state of the powder, including its appearance and color, before opening the weak-weld isolation strip between the chambers for mixing. According to clinical observations, some veterinarians may, due to improper operation, neglect the necessary inspection steps when using such products, directly squeeze and open the isolation strip between the powder-liquid double-chambers without opening the external barrier film and hang it for infusion, thus bringing potential risks to clinical safety. In addition, in the current design, the positioning holes on both sides of the bag body are used as hanging holes at the same time. Since the hanging points are far from the central axis of the bag body, the bag will tilt, resulting in incomplete drainage of the liquid medicine and affecting the treatment effect.

[0004] Therefore, in view of the above situation, in order to improve the safety and effectiveness of use, there is an urgent need to develop a powder-liquid double-chamber bag to overcome the deficiencies in current practical applications. Summary of the Invention

[0005] The purpose of the present invention is to provide a powder-liquid double-chamber bag, aiming to solve the problems mentioned in the above background art.

[0006] The present invention is realized as follows. A powder-liquid double-chamber bag includes a medicine bag. Inside the medicine bag, a first chamber bag and a second chamber bag are independently arranged. The first chamber bag and the second chamber bag are respectively used for containing powder medicine grains and liquid medicine. A weak-weld isolation strip for blocking the communication between the first chamber bag and the second chamber bag is arranged between the first chamber bag and the second chamber bag. When the second chamber bag is squeezed, the liquid in the second chamber bag breaks through the weak-weld isolation strip and flows into the inner cavity of the first chamber bag and mixes with the powder in the first chamber bag. An infusion port is installed on the medicine bag at one end of the second chamber bag away from the first chamber bag, and the infusion port is communicated with the second chamber bag. A hanging hole is arranged at one end of the medicine bag away from the infusion port. A peelable barrier film is also attached to one side of the medicine bag.

[0007] The edges of the first chamber bag and the second chamber bag are sealed by solid soldering;

[0008] The peelable barrier film fits and covers the first chamber bag, the weak solder isolation strip, and the suspension hole.

[0009] In a further technical solution, an unpeelable barrier film is further provided on the side of the medicine bag away from the peelable barrier film, and the unpeelable barrier film does not cover the suspension hole.

[0010] In a further technical solution, a starting seal is further provided at one end of the peelable barrier film close to the weak solder isolation strip. The starting seal and the medicine bag are arranged with a gap. A blocking piece is provided at the other end of the peelable barrier film, and the blocking piece is arranged on the side close to the suspension hole.

[0011] In a further technical solution, the medicine bag has an opposite first surface, and the peelable barrier film has an opposite second surface. The second surface fits on the first surface, and the second surface covers one side of the suspension hole. The suspension hole is arranged in the middle of the first surface.

[0012] A powder-liquid double-chamber bag provided by the present invention has the following beneficial effects:

[0013] By providing a peelable barrier film on one side of the medicine bag, and a blocking piece for blocking the suspension hole is provided at one end of the peelable barrier film, it can force the user to inspect the pharmaceutical powder in the medicine bag before infusion, avoiding potential safety hazards.

[0017] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0018] The following describes the specific implementation of the present invention in detail with reference to specific embodiments.

[0019] As Figure 1-2As shown in the figure, a powder-liquid double-chamber bag provided by an embodiment of the present invention includes a medicine bag 1. Inside the medicine bag 1, a first chamber bag 2 and a second chamber bag 3 are independently arranged. The first chamber bag 2 and the second chamber bag 3 are respectively used for containing powder medicine grains and liquid medicine. A weak-weld isolation strip 4 for blocking the communication between the first chamber bag 2 and the second chamber bag 3 is arranged 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 weak-weld isolation strip 4 and then flows into the inner cavity of the first chamber bag 2 and mixes with the powder in the first chamber bag 2. At one end of the second chamber bag 3 away from the first chamber bag 2, an infusion port 5 is installed on the medicine bag 1, and the infusion port 5 is communicated with the second chamber bag 3. A hanging hole 6 is arranged at one 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 the embodiment of the present invention, when using this powder-liquid double-chamber bag, the first chamber bag 2 and the second chamber bag 3 are respectively used for containing powder medicine grains and liquid medicine. When the user uses this medicine bag, first, the user needs to find the slit at the bottom edge position 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 of the medicine bag 1. At this time, the user can clearly observe the powder state 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 orifice of the hanging hole 6 is in an open state. At this time, the user places the medicine bag 1 flat on the tabletop, and then squeezes the second chamber bag 3 by hand to continuously increase the internal pressure of the second chamber bag 3. When the liquid pressure exceeds the threshold value, the liquid breaks through the weak-weld isolation strip 4 and then 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 hang the medicine bag on the bracket through the hanging hole 6 for infusion.

[0021] As a preferred embodiment of the present invention, an unpeelable barrier film is also arranged on the side of the medicine bag 1 away from the peelable barrier film 7, and the unpeelable barrier film does not cover the hanging hole 6.

[0022] As a preferred embodiment of the present invention, the edge positions of the first chamber bag 2 and the second chamber bag 3 are both sealed by solid welding to ensure the sealing performance of the medicine bag 1.

[0023] As Figure 2 shown, as a preferred embodiment of the present invention, the peelable barrier film 7 fits and covers the first chamber bag 2, the weak-weld isolation strip 4, and the hanging hole 6 to ensure that a completely light-shielding surface is formed on one side of the first chamber bag 2 by the peelable barrier film 7.

[0024] Preferably, a starting seal 8 is also arranged at one end of the peelable barrier film 7 close to the weak-weld isolation strip 4. The starting seal 8 and the medicine bag 1 are arranged with a gap. A blocking piece 9 is arranged at the other end of the peelable barrier film 7, and the blocking piece 9 is arranged on the side close to the hanging hole 6.

[0025] During application, a gap is left between the sealing strip 8 and the outer surface of the medicine bag 1, so that when the user peels off the peelable barrier film 7, through the gap left on one side of the sealing strip 8, after pushing up one end of the sealing strip 8, the peelable barrier film 7 can be detached from the surface of the medicine bag 1 by pulling the sealing strip 8; the blocking piece 9 is attached to one side of the hanging hole 6, so that when the peelable barrier film 7 is in a fitting state, the hanging hole 6 is in a blocked state, preventing the user from directly performing infusion without checking the mixing state of the medicinal powder and the medicament.

[0026] It can be understood that, as Figure 2 shown, the medicine bag 1 has an opposite first surface a, the peelable barrier film 7 has an opposite second surface b, the second surface b is attached to the first surface a, and the second surface b covers one side of the hanging hole 6, and the hanging hole 6 is arranged in the middle of the first surface a. The first surface a and the second surface b are in a tightly attached state in the use state, and the second surface b is difficult to be directly torn off from the first surface a side in the attached state, preventing the user from directly locally peeling off the barrier film 7 from the first surface a and then directly using the hanging hole 6 to hang the medicine bag. Moreover, the hanging hole 6 is arranged in the middle of the first surface a, so that during the hanging process, the medicament inside the medicine bag 1 can flow out smoothly, avoiding the retention of residual liquid medicine.

[0027] In the above-mentioned embodiment of the present invention, a powder-liquid double-chamber bag is provided. By arranging a peelable barrier film 7 on one side of the medicine bag 1, and a blocking piece 9 for blocking the hanging hole 6 is arranged at one end of the peelable barrier film 7, it is possible to force the user to inspect the medicament powder in the medicine bag 1 before infusion, avoiding potential safety hazards.

[0028] The technical features of the above-mentioned embodiments can be combined arbitrarily. For the sake of brief description, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0029] The above-mentioned embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it cannot be understood as a limitation to the scope of the invention patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the invention patent of the present invention should be subject to the appended claims.
