Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a sealing device for infusion bags. Background Technology

[0002] In the medical field, infusion bags are common medical supplies widely used to deliver essential medical fluids such as glucose and saline solution into patients. The airtight seal of infusion bags is crucial for ensuring the purity of the medical fluids and preventing bacterial infection.

[0003] Traditional IV bag sealing devices are mainly achieved through bottle cap stickers. When the liquid in the IV bag needs to be used, the syringe needle will penetrate the sealing plug to enter the IV bag for extraction. After the liquid is extracted, the hole left on the sealing plug will allow outside air to circulate. By attaching the bottle cap sticker to the hole left on the sealing plug, a seal is achieved, thus isolating the air.

[0004] However, the sealing performance of the bottle cap sticker depends on the bonding method. After it is applied, medical staff need to rub it back and forth on the sealing plug to ensure maximum airtightness. When busy, it is usually simply applied to the sealing plug of the infusion bag, resulting in poor airtightness. Moreover, the bottle cap sticker is designed to be separate from the infusion bag, making it easier to forget to apply the bottle cap sticker to the sealing plug of the infusion bag when busy.

[0005] To address the shortcomings of existing technologies, this invention proposes a novel sealing device for infusion bags. This device achieves better sealing performance and more convenient operation through optimized sealing structure design. Utility Model Content

[0022] Example 1, as shown in Figures 1-3, is a sealing device for an infusion bag, including an infusion bag 1, with multiple hanging holes 2 at the bottom of the infusion bag 1, an infusion head 3 fixed to the top of the infusion bag 1, a sealing plug 31 embedded in the infusion head 3, and a convenient sealing device 4 fixedly connected to the top of the infusion bag 1 outside the infusion head 3.

[0023] Specifically, the infusion bag 1 contains glucose or saline solution. When needed, the syringe needle is inserted through the sealing plug 31 of the infusion head 3 to draw liquid from the infusion bag 1. After drawing liquid, the needle is pulled out of the sealing plug 31. At this time, the hole left by the sealing plug 31 allows air to circulate, which can easily lead to bacterial growth in the liquid inside the infusion bag 1. The convenient sealing device 4 seals the bag, isolating it from the outside air and effectively preventing bacterial growth inside the infusion bag 1.

[0024] In this embodiment, the convenient sealing device 4 includes a connecting ring 44 sleeved on the lower part of the sealing plug 31. A connecting band 42 is fixedly connected to one side of the connecting ring 44, and a sealing cap 41 is fixedly connected to the other end of the connecting band 42. A sealing rubber ring 43 is fixed to the inner wall of the sealing cap 41, and the sealing cap 41 is fitted and sealed with the infusion head 3.

[0025] Specifically, using the convenient sealing device 4, when drawing fluid, the sealing cap 41 is pried open and separated from the infusion head 3, exposing the sealing plug 31 for drawing fluid. After drawing, the sealing cap 41 is then grasped and embedded into the infusion head 3. The sealing ring 43 is squeezed to achieve a seal, isolating external air and effectively preventing bacteria from growing inside the infusion bag 1. This structure is easy to open and seal, and its integrated design with the infusion bag is not easily overlooked.

[0026] In Example 2, based on Example 1, a convenient sealing device 2 5 is fixedly connected to the top of the infusion bag 1 outside the infusion head 3. The convenient sealing device 2 5 includes a transparent sealing sleeve 51 fixedly connected to the infusion bag 1. Pull ears 53 are fixedly attached to the front and rear of the top of the transparent sealing sleeve 51. A sealing structure 52 is provided at the opening edge of the transparent sealing sleeve 51. A transparent insert sleeve 54 is fixedly connected to the outside of the transparent sealing sleeve 51. A note card 55 is inserted into the transparent insert sleeve 54.

[0027] Specifically, the transparent sealing sleeve 51 is fitted onto the infusion head 3. When drawing liquid, the transparent sealing sleeve 51 can be turned outward to expose the infusion head 3, making it easier for the syringe to pierce and draw the liquid. After completion, the transparent sealing sleeve 51 is turned back up to cover the infusion head 3, and its top opening is sealed by the sealing structure 52 to isolate external air and effectively prevent bacteria from growing inside the infusion bag 1. The transparent infusion bag 1 is also equipped with a transparent insert sleeve 54, on which the date and purpose of use of the infusion bag 1 can be recorded on a note card 55. This card can then be inserted into the transparent insert sleeve 54 for easy reference during the next use. The transparent sealing sleeve 51 is also equipped with two staggered pull tabs 53, which make it easy to quickly open the transparent sealing sleeve 51 and open the sealing structure 52 when opening later.

[0028] In this embodiment, the sealing structure 52 is a press-fit sealing strip, which consists of a protruding strip 521 and a concave strip 522 fixed on both sides of the top opening inside the infusion bag 1.

[0029] Specifically, when the sealing structure 52 is a press-fit sealing strip, by pressing the opening of the transparent sealing sleeve 51, the protruding strip 521 and the concave strip 522 are squeezed and engaged together, thereby achieving the airtightness of the press-fit transparent sealing sleeve 51 and protecting the liquid inside the infusion bag 1.

[0030] In Example 3, based on Example 2, the sealing structure 52 is a magnetic sealing strip, which consists of two sets of rubber magnetic strips 523 fixed on both sides of the top opening inside the infusion bag 1. The two rubber magnetic strips 523 are different magnets.

[0031] Specifically, when the sealing structure 52 is a magnetic sealing strip, by pressing the opening of the transparent sealing sleeve 51, the rubber magnetic strip 523 is magnetically attracted together, thereby achieving airtightness of the transparent sealing sleeve 51 and protecting the liquid inside the infusion bag 1.

[0032] In Example 4, based on Example 1, the sealing structure 52 is a combination of a pressure-sealing strip and a magnetic sealing strip.

[0033] Specifically, when the sealing structure 52 is a combination of a pressure-sealing strip and a magnetic sealing strip, the first layer is a conventional toothed interlocking to provide a basic seal, and the second layer is squeezed together by the protruding strip 521 and the concave strip 522 to achieve a press-sealed airtight seal and protect the liquid inside the infusion bag 1.

[0034] Working principle:

[0035] The infusion bag 1 contains glucose or saline solution. When needed, the syringe needle is inserted through the sealing plug 31 of the infusion head 3 to draw liquid from the infusion bag 1. After drawing liquid, the needle is pulled out of the sealing plug 31. At this time, the hole left by the sealing plug 31 is in contact with the outside air, which can easily lead to the growth of bacteria in the liquid inside the infusion bag 1. Therefore, it needs to be sealed by the sealing structure 52.

[0036] With the convenient sealing device 4, when drawing liquid, the sealing cap 41 is pried open and separated from the infusion head 3, exposing the sealing plug 31 for drawing liquid. After that, the sealing cap 41 is grasped and embedded into the infusion head 3. The sealing ring 43 is squeezed to achieve a seal, isolating external air and effectively preventing bacteria from growing inside the infusion bag 1. This structure is easy to open and seal, and its integrated design with the infusion bag is not easy to overlook.

[0037] The transparent sealing sleeve 51 is fitted onto the infusion head 3. When drawing liquid, the transparent sealing sleeve 51 can be turned outward to expose the infusion head 3, making it easier for the syringe to pierce and draw the liquid. After completion, the transparent sealing sleeve 51 is turned back up to cover the infusion head 3, and the top opening is sealed by the sealing structure 52 to isolate external air and effectively prevent bacteria from growing inside the infusion bag 1. The transparent infusion bag 1 is also equipped with a transparent insert sleeve 54, which can record the date and purpose of use of the infusion bag 1 on a note card 55. The card can then be inserted into the transparent insert sleeve 54 for note-taking, making it easy to check the information next time. The transparent sealing sleeve 51 is also equipped with two staggered pull tabs 53, which make it easy to quickly open the transparent sealing sleeve 51 and open the sealing structure 52 when opening the bag later.

[0038] When the sealing structure 52 is a press-fit sealing strip, by pressing the opening of the transparent sealing sleeve 51, the protrusion 521 and the concave strip 522 are squeezed and bit together, thereby achieving the airtightness of the press-fit transparent sealing sleeve 51 and protecting the liquid inside the infusion bag 1.

[0039] When the sealing structure 52 is a magnetic sealing strip, by pressing the opening of the transparent sealing sleeve 51, the rubber magnetic strip 523 is magnetically attracted together, thereby achieving the airtightness of the transparent sealing sleeve 51 and protecting the liquid inside the infusion bag 1;

[0040] When the sealing structure 52 is a combination of the pressure sealing strip and the magnetic sealing strip, the first layer is a conventional toothed interlocking to provide a basic seal, and the second layer is squeezed together by the convex strip 521 and the concave strip 522 to achieve a press-fit airtight seal and protect the liquid inside the infusion bag 1.
