Description

Technical Field

[0001] This application relates to the field of medical device technology, and more specifically, to a sterile puncture blood bag. Background Technology

[0002] In fields such as biology and medicine, sealed blood bags are often used to hold sterilized blood. During blood transfer, blood needs to be drawn from the blood bag by puncture. However, the puncture procedure can easily introduce bacteria, leading to blood contamination.

[0003] Currently, the common procedure for blood biopsies involves placing a sealing rubber stopper on the blood bag. During the procedure, alcohol swabs or other disinfectant items are used to wipe and disinfect the exposed surfaces of the needle and the sealing rubber stopper before the needle punctures the stopper to extract the fluid. However, this method of surface wiping is insufficient to completely inactivate all microorganisms. During insertion, the needle surface comes into contact with the outside air and the opening of the blood bag, carrying bacteria and other contaminants. Summary of the Invention

[0004] This application provides a blood bag for aseptic puncture, which enables aseptic puncture and avoids blood contamination.

[0005] This application provides a sterile puncture blood bag, comprising: a culture bag having an internal cavity for containing blood; and a sterile insertion assembly sealed to the culture bag and communicating with the cavity. The sterile insertion assembly includes an interface housing, an insertion channel inside the interface housing, and an insertion portion at the port. A disinfection module, a drying module, and a connecting cavity are sequentially arranged within the insertion channel along a first direction away from the insertion portion. The connecting cavity communicates with the cavity. The disinfection module is used to disinfect the puncture needle, and the drying module is used to dry the disinfected puncture needle.

[0006] In some embodiments, the interface housing is integrally formed and connected to the culture bag.

[0007] In some embodiments, the disinfection module includes a porous adsorption carrier soaked in disinfectant.

[0008] In some embodiments, the porous adsorption carrier is a sponge block, a non-woven fabric block, or a fiber cotton block.

[0009] In some embodiments, the disinfection module has a insertion channel in the middle for the puncture needle to pass through.

[0010] In some embodiments, the drying module includes two recoverable elastic plugs disposed opposite each other along the first direction, a drying chamber formed by the elastic plugs and the inner wall of the insertion channel, and a dry sterile gas pre-filled in the drying chamber.

[0011] In some embodiments, the plug portion includes a plug cap, which is a resilient plug cap that can be restored.

[0012] In some embodiments, the connector cap is detachably sealed to the port of the interface housing.

[0013] In some embodiments, at least a portion of the interface housing is made of a transparent material to allow observation of the drying status of the puncture needle within the drying module.

[0014] In some embodiments, the culture bag is provided with at least one hanging ring.

[0015] In this embodiment, by sequentially arranging a disinfection module and a drying module inside the insertion channel, the puncture needle undergoes sterilization via the disinfection module before entering the blood bag's receiving cavity, and residual disinfectant is removed via the drying module. This effectively prevents contamination caused by disinfectant being carried into the bloodstream by the puncture needle, achieving aseptic operation during the puncture process. This application features a compact structure, convenient and efficient operation, and low cost. Attached Figure Description

[0033] In this application, "multiple" means two or more (including two).

[0034] Please refer to Figure 1 , Figure 3 and Figure 4 This application provides a sterile puncture blood bag, mainly comprising a culture bag 1 and a sterile insertion assembly 2, wherein the culture bag 1 has an internal cavity for containing blood products, and the sterile insertion assembly 2 is sealed to the outer wall of the culture bag 1 and communicates with the cavity.

[0035] The sterile insertion assembly 2 includes an interface housing 21, which has a tubular structure and a plug-in portion at one end. The plug-in portion is sealed to the interface housing 21. An insertion channel is provided inside the interface housing 21, extending axially and allowing the insertion of a puncture needle 3. The plug-in portion can be made of an elastic, repositionable material, such as rubber. If the puncture needle 3 does not puncture the insertion point or after puncture, the plug-in portion completely seals the port of the interface housing 21, preventing liquid or gas leakage. When the puncture needle 3 punctures, it can penetrate the plug-in portion to enter the insertion channel.

[0036] The insertion channel is provided with a disinfection module 22, a drying module 23 and a connection cavity 24. The disinfection module 22, the drying module 23 and the connection cavity 24 are arranged sequentially from the outside to the inside along the first direction X (i.e. the axial direction of the insertion channel) and away from the insertion part.

[0037] The disinfection module 22 is disposed within the insertion channel near one end of the insertion part, and is tightly fitted and fixed to the inner wall of the insertion channel. The disinfection module 22 can be a disinfectant carrier, such as a container storing disinfectant or a material adsorbing disinfectant. The disinfection module 22 can be made of soft or elastic material, allowing the puncture needle 3 to be inserted. When the puncture needle 3 is inserted through the insertion part and passes through the disinfection module 22, the surface of the needle is coated with disinfectant.

[0038] The drying module 23 is located inside the disinfection module 22, away from the insertion part, and between the disinfection module 22 and the connecting cavity 24. When the puncture needle 3 with disinfectant on its surface enters the drying module 23, the liquid disinfectant attached to the puncture needle 3 is dried and evaporated to prevent the needle from carrying disinfectant into the receiving cavity of the culture bag 1.

[0039] The connecting cavity 24 is located inside the drying module 23. This connecting cavity 24 is a drying cavity, with one end adjacent to the drying module 23 and the other end directly connected to the receiving cavity of the culture bag 1. The puncture needle 3 finally enters the receiving cavity through this connecting cavity 24.

[0040] refer to Figure 3 , Figure 4 and Figure 5 During the puncture process, the puncture needle 3 is first inserted into the connector, then punctures through the disinfection module 22, rotating several times to ensure that the puncture needle 3 is fully coated with disinfectant and that the disinfectant is evenly applied. The puncture needle 3 is then inserted into the drying module 23, and after the disinfectant has evaporated, it is inserted into the connection cavity 24 to complete the aseptic puncture.

[0041] The aseptic puncture blood bag provided in this application solves the problems of incomplete disinfection and easy introduction of contamination in traditional puncture methods, thus achieving aseptic puncture.

[0042] In one specific embodiment, the interface shell 21 is integrally formed and connected to the culture bag 1, thereby eliminating the defects such as seams and weak bonding that exist in separate plug-in methods, and avoiding leakage and contamination. In addition, the integrally formed structure is not easily damaged or detached during the puncture operation, meets the needs of multiple puncture operations, and extends the service life of the sterile puncture blood bag.

[0043] The culture bag 1 is also equipped with a connecting tube 12, which can be one or more and is integrally formed with the culture bag 1. Multiple culture bags 1 can be connected through the connecting tube 12 to form a multi-bag, thereby increasing the capacity.

[0044] The disinfectant used in this embodiment may be, but is not limited to, iodine tincture, alcohol, etc. In one specific embodiment, the disinfection module 22 includes a porous adsorption carrier soaked in disinfectant. The porous adsorption carrier may be a sponge block, a non-woven fabric block, or a fiber cotton block, and may be cylindrical, multi-layered, spiral, etc. The porous adsorption carrier has multiple mesh structures or microporous structures inside, which can absorb and store a large amount of disinfectant. It can come into contact with the disinfection module 22 during the puncture of the puncture needle 3, fully contacting the needle surface, and applying the disinfectant absorbed in the adsorption carrier to the needle body of the puncture needle 3, making the application more uniform. The disinfection module 22 may be fixed in the slot of the insertion channel inside the interface housing 21, or welded or bonded to the inside of the insertion channel.

[0045] Continue to refer to Figure 2 Furthermore, the disinfection module 22 has a connector channel 221 in the middle for the needle body of the puncture needle 3 to pass through. The diameter of the connector channel 221 is slightly smaller than the diameter of the needle body of the puncture needle 3. Since the disinfection module 22 can deform, the needle body of the puncture needle 3 can be wrapped and evenly coated during the process of passing through the connector channel 221. At the same time, the connector channel 221 can reduce puncture debris.

[0046] refer to Figure 2 In one specific embodiment, the drying module 23 includes two resilient elastic plugs 231, which may be, but are not limited to, rubber plugs. The elastic plugs 231 are arranged opposite each other along a first direction X, and the elastic plugs 231 and the inner wall of the insertion channel form a drying chamber 232, which is pre-filled with sterile drying gas. The rubber plugs can be restored after puncture, sealing the puncture site to prevent leakage, and allowing for repeated punctures by the puncture needle 3.

[0047] After the puncture needle 3 is inserted into the elastic plug 231 on the inlet side, it enters the drying chamber 232, which provides a dry environment for the disinfectant. The disinfectant adhering to the surface of the needle body is volatilized before the needle is inserted into the elastic plug 231 on the other side to complete the aseptic puncture.

[0048] In addition, the connector includes a socket cap 25, which is a resilient socket cap, such as a rubber cap. When the puncture needle 3 punctures the socket cap 25, the puncture needle 3 can pass through easily, and after puncture, the socket cap 25 quickly recovers and maintains a sealed state.

[0049] The connector cap 25 is detachably sealed to the port of the interface housing 21. For example, the two can be connected by threads and secured with a sealing ring, or they can be interlocked for sealing and securing, to facilitate assembly and replacement of the internal disinfection module 22. A peel-off sealing film can be attached to the outside of the connector cap 25 to enhance the sealing effect.

[0050] In addition, at least part of the interface housing 21 is made of transparent material, which allows for easy observation of the evaporation of disinfectant on the surface of the puncture needle 3 inside the drying module 23, thereby accurately controlling the drying status, saving waiting time, and improving operational efficiency.

[0051] To facilitate the hanging and fixing of the culture bag 1, at least one hanging ring 11 can be provided on the culture bag 1. The hanging ring 11 can be set on the upper part of the culture bag 1, providing an interface for connection with the outside, which facilitates storage and transportation and improves the convenience of operation.

Specific examples have been used to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of this application.
