Description

Technical Field

[0001] This application relates to the field of sterile syringe equipment technology, and more particularly to a packaging bag for sterile syringes. Background Technology

[0002] The statements in this section are merely background information related to this application and do not necessarily constitute prior art.

[0003] Vacuum packaging is not mandatory for sterile syringes, but the packaging must ensure the integrity of the sterility barrier. Whether to use vacuum packaging depends on the sterilization method and transportation / storage requirements; for example, irradiated sterilized plastic syringes may use vacuum or negative pressure packaging to enhance sealing and stability.

[0004] For sterile syringes that require vacuum packaging, the typical production process involves placing the needle-free syringe into a bag, then vacuuming the bag before sealing it. This process allows a small amount of gas to easily get into the bag during sealing, affecting sterility. Furthermore, sterile syringe packaging bags are consumables and must be specifically recycled. All used packaging bags must be collected and disposed of according to regulations.

[0005] However, during use, it was found that when staff tore open the packaging of the sterile syringe, they encountered a problem. Figure 1 As is commonly used in existing technologies, when manually tearing the bag from the toothed edge 3, it is easy to tear the packaging bag into two halves of different sizes, and often a small corner is torn off; during recycling, the torn corner is easily overlooked.

[0006] Therefore, it is necessary to provide a packaging bag for sterile syringes to solve the above-mentioned technical problems. Summary of the Invention

[0007] Based on this, and in response to the aforementioned technical problems, this application provides a packaging bag for sterile syringes.

[0008] The technical solution adopted in this application to solve the problems existing in the prior art is: This application discloses a packaging bag for sterile syringes, including a bag body, an opening on one side of the bag body, and a toothed edge on the edge of the opening; The opening of the bag is sealed with an adhesive strip; The bag is equipped with a one-way valve, which is positioned from the inside out.

[0009] Preferably, The inside of the bag is divided into a head compartment, a neck compartment, and a tail compartment from the opening to the bottom. The cross-sectional area of ​​the neck containment area is smaller than that of the tail containment area.

[0010] Preferably, The head receiving area is used to receive the syringe head; the neck receiving area is used to receive the syringe neck; and the tail receiving area is used to receive the syringe tail.

[0011] Preferably, The bag inside the neck compartment is made of an elastomer.

[0012] Preferably, The bag is equipped with a connecting rope inside. One end of the connecting rope starts from one side of the opening and goes around the inner edge of the bag to the other side of the opening.

[0013] Preferably, The connecting rope is attached to the inside of the bag.

[0014] Preferably, The bag has a sealed edge on the outside.

[0015] Preferably, One-way valve port size ≤ 1 / 4 inch.

[0016] Compared with the prior art, the beneficial effects of this application are as follows: 1. The design of the connecting rope 5 ensures that the bag body 1 will not be torn in half, making it convenient for the unified recycling and disposal of the bag body.

[0017] 2. When producing bag body 1, it is not necessary to vacuum first. Instead, seal the edges first, and then squeeze bag body 1 to expel the gas inside bag body 1 through one-way valve 6. This improves the sterility effect.

[0018] 3. When packaging the syringe through the bag 1, the head receiving area 9 contains the syringe head 90; the neck receiving area 7 contains the syringe neck 70; and the tail receiving area 8 contains the syringe tail 80. Because the neck is large, when the staff tears the bag 1 from the toothed edge 3, the bag 1 is torn to the neck receiving area 7, and the syringe will still be inside the bag 1 and will not fall out.

[0022] The present application will be further described below with reference to the accompanying drawings and embodiments.

[0023] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this disclosure. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0024] In this disclosure, terms such as "upper," "lower," "left," "right," "front," "back," "vertical," "horizontal," "side," and "bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are merely relational terms determined for the convenience of describing the structural relationship of the various components or elements in this disclosure, and do not specifically refer to any component or element in this disclosure, nor should they be construed as limiting this disclosure.

[0025] refer to Figure 2 This is a schematic diagram of the overall structure of a packaging bag for a sterile syringe according to the first embodiment of this application; Figure 3 This is a schematic diagram of the overall structure of a packaging bag for a sterile syringe according to the second embodiment of this application; Figure 4 This is a schematic diagram of the overall structure of a needle-free injector. Figure 1 This is a schematic diagram of the overall structure of a syringe packaging bag in the prior art; The sterile syringe packaging bag of this application includes a bag body 1, with an opening on one side and a toothed edge 3 along the edge of the opening; the opening of the bag body 1 is sealed by an adhesive strip 2; a one-way valve 6 is provided on the bag body 1, with the one-way valve 6 oriented from the inside out. A sealing edge 4 is provided on the outside of the bag body 1.

[0026] In some embodiments, reference Figure 4The bag body 1 is formed from the opening to the bottom as a head receiving area 9, a neck receiving area 7 and a tail receiving area 8; wherein the straight-line area of ​​the neck receiving area 7 is smaller than that of the tail receiving area 8.

[0027] Wherein: head receiving area 9 is used to receive syringe head 90; neck receiving area 7 is used to receive syringe neck 70; tail receiving area 8 is used to receive syringe tail 80.

[0028] In some embodiments, the bag 1 within the neck receiving area 7 is elastic.

[0029] In some embodiments, a connecting rope 5 is provided inside the bag body 1. One end of the connecting rope 5 starts from one side of the opening and wraps around the inner edge of the bag body 1 to the other side of the opening. The connecting rope 5 is adhered to the inside of the bag body 1.

[0030] The one-way valve 6 has an interface size of ≤1 / 4 inch; in some embodiments, the one-way valve 6 is a Parker CV-1 series PTFE one-way valve with a minimum interface size of 1 / 8 inch and an opening pressure as low as 0.017 bar.

[0031] Working principle: The design of the one-way valve 6 primarily considers the manufacturing process of the bag body 1. As mentioned in the background section, for sterile syringes requiring vacuum packaging, the typical production process involves placing the needle-free syringe into the bag body, then vacuuming the bag, followed by sealing the edges. This process allows a small amount of gas to easily enter the bag during sealing, affecting sterility. Therefore, this application designs the one-way valve 6. During bag body 1 production, vacuuming can be skipped; the edges can be sealed first, and then the gas inside the bag body 1 can be expelled through the one-way valve 6 by squeezing the bag body 1, thus improving sterility.

[0032] refer to Figure 3 , Figure 3 The design has two aspects. One is that when the syringe is packaged in the bag 1, the head receiving area 9 contains the syringe head 90; the neck receiving area 7 contains the syringe neck 70; and the tail receiving area 8 contains the syringe tail 80. Because the neck is large, when the staff tears the bag 1 from the toothed edge 3, the bag 1 is torn to the neck receiving area 7, and the syringe will still be inside the bag 1 and will not fall out. The sealing edge 4 in the figure is formed by folding and gluing together a single piece of plastic raw material during the manufacturing process of the bag body 1. This is a common technique used by those skilled in the art and will not be elaborated upon here.

[0033] The second aspect is the design of the connecting rope 5, which ensures that the bag body 1 will not be torn in half, making it convenient for the unified recycling and disposal of the bag body.

[0034] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.

[0035] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0036] While the specific embodiments of this application have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of this application. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of this application are still within the scope of protection of this application.
