Description

TECHNICAL FIELD

[0001] The utility model relates to cell transfer technical field, more specifically, it relates to a novel structure's cell transfer bag. BACKGROUND

[0002] In the cell treatment process, often will meet a situation, that is, cell in cell preparation center makes preparation and fills into disposable cell transfer bag, then transports to the hospital of patient receiving cell treatment. From cell preparation center preparation completion to patient use cell needs to experience an interval, and cell transfer bag can meet jolt and collision in the transportation, all can influence cell activity, how to take cell preparation sample in transfer bag before patient uses cell to do cell activity and cell amount detection is a difficult thing. SUMMARY

[0003] The utility model discloses a novel structure's cell transfer bag to solve the technical problems in the background art.

[0004] In order to realize the above-mentioned purpose, the utility model adopts the following technical scheme:

[0005] A novel structure's cell transfer bag, including: transfer bag, input port, liquid inlet pipe, output port are connected on the transfer bag respectively, still including sampling bag, the sampling bag is communicated with the transfer bag through plastic hose, and the sampling bag is closed bag body.

[0006] In some embodiments, the sampling bag volume is 2-3ml.

[0007] In some embodiments, the length of plastic hose is 2-3cm.

[0008] In some embodiments, the wall thickness of plastic hose is 0.5-1mm.

[0009] In some embodiments, the outer wall of sampling bag is equipped with a pull ring.

[0010] The utility model has the beneficial effects compared with prior art:

[0011] The utility model structure is novel, and practicality is strong, and the upper end of transfer bag is connected with sampling bag through plastic hose, when needing to sample cell preparation, manually extrudes 1-2ml cell suspension into sampling bag, then heat seals plastic hose between sampling bag and transfer bag, after heat sealing, removes sampling bag and can carry out cell activity and cell amount detection, and sampling is convenient and sterile.

[0014] In order to make the objects, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in detail below with reference to the drawings of the preferred embodiments of the present application. Identical or similar labels in the drawings represent identical or similar components or components with identical or similar functions throughout. The described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0015] The embodiments of the present application will be described in detail below with reference to the drawings.

[0016] In the description of the present application, it should be noted that unless explicitly defined and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or indirectly connected through an intermediate medium, or the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0017] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0018] In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or display including a series of steps or units need not be limited to only those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or displays.

[0019] The following will be described in combination with Figure 1, a novel cell transfer bag according to the embodiment of the present application is described in detail. It should be noted that the following embodiments are only used to explain the present application and do not constitute a limitation of the present application.

[0020] Embodiment 1:

[0021] like Figure 1 As shown, a cell transfer bag with a novel structure includes a transfer bag 1, an input port 2, a liquid inlet conduit 3, an output port 4 and a sampling bag 6. The upper end of the transfer bag 1 is connected to the sampling bag 6 through a plastic hose 5. The volume of the sampling bag is 2-3 ml. When it is necessary to sample the cell preparation, 1-2 ml of cell suspension is manually squeezed into the sampling bag, and then the plastic hose between the sampling bag and the transfer bag is heat-sealed. After the heat sealing is completed, the sampling bag is removed to perform cell activity and cell quantity detection. Sampling is convenient and sterile.

[0022] In some embodiments, the sampling bag has a volume of 2-3 ml. The sampling bag has a volume larger than that of a single sample in order to facilitate subsequent heat sealing and separation, and to provide sufficient space to avoid leakage from the heat sealing.

[0023] In some embodiments, the length of the plastic hose is 2-3 cm, and the wall thickness of the plastic hose is 0.5-1 mm, which facilitates subsequent heat sealing to separate the sampling bag and the transfer bag.

[0024] In some embodiments, a pull ring 7 is provided on the outer wall of the sampling bag. The pull ring is used to pull the sampling bag during heat sealing to avoid damage to the sampling bag during heat sealing.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
