[0024] Figure 1 It is a schematic diagram of an embodiment of the liquid storage bag of the utility model.

[0025] The sterile liquid storage bag 1 of the utility model is used to store liquid and to pack the stored liquid. The liquid storage bag 1 comprises a side wall. Figure 1In the embodiment, the liquid storage bag 1 includes a front side wall 41 and a rear side wall (not shown in the figure), and the front side wall 41 and the rear side wall periphery are closed to form a holding portion 2 and a liquid storage portion 3. In the optional embodiment, the form of the liquid storage bag 1 is not limited, and can be integrally formed, formed by closing the edges of multiple side walls, or formed by closing the edges of multiple side walls and the bottom wall.

[0026] The shape of the liquid storage bag 1 is not limited and can be Figure 1 In the embodiment of the present invention, the liquid storage bag 1 is square, and the square liquid storage bag is convenient for the layout of its inner space. In an optional embodiment, the liquid storage bag 1 can also be circular, polygonal, etc.

[0027] The holding portion 2 is used to maintain the shape of the liquid storage bag 1 when storing and dispensing liquid, so as to ensure that the liquid stored in the liquid storage bag 1 will not fall over or accumulate due to the change in the shape of the liquid storage bag 1.

[0028] In the illustrated example, the holding portion 2 includes a hanging hole 21, through which the operator can hang the liquid storage bag 1 on an external hanging portion, such as a hook, a hanging nail, etc. Further, a limiting notch 22 is provided in the middle of the force-applying side of the hanging hole 21, and when hanging, the limiting notch 22 can limit the external hanging portion there, and the limiting notch 22 can further limit the position of the liquid storage bag 1 to prevent the liquid storage bag 1 from sliding and affecting the storage and packaging of the liquid.

[0029] Furthermore, a reinforcing device 23 may be provided at the hanging hole 21, and the reinforcing device 23 is used to support the liquid storage bag 1. The reinforcing device 23 can prevent the liquid storage bag 1 from being deformed due to the gravity of the liquid stored therein when hanging, thereby affecting the storage and packaging of the liquid.

[0030] According to the embodiment in the figure, the reinforcing device can be a support rod, which is encapsulated on the force side of the hanging hole 21 through an isolation line 24. The isolation line 24 is located on both sides of the support rod to limit the position of the support rod and prevent it from falling off.

[0031] When hanging, the longitudinal direction of the support rod can support the lateral direction of the liquid storage bag 1 to prevent the lateral ends of the liquid storage bag 1 from collapsing due to gravity, thereby maintaining the shape of the liquid storage bag 1.

[0032] The liquid storage part 3 includes a liquid storage space 4. Figure 1 In the embodiment, the liquid storage space 4 is surrounded by a front side wall 41 and a rear side wall for storing liquid. In other embodiments, the liquid storage space 4 can also be surrounded by a plurality of side walls and a bottom wall.

[0033] As shown in the figure, the periphery of the liquid storage space 4 is sealed and closed by a sealing line 42, thereby forming a sealed and closed liquid storage space 4, which can prevent the liquid stored therein from leaking. At the same time, the sealed and closed liquid storage space 4 can also maintain a sterile state to avoid the risk of contamination of the liquid stored therein.

[0034] The sealing line 42 may be wider than the isolation line 24 . The wider sealing line 42 may further increase the sealing performance of the liquid storage bag 1 , thereby better sealing the liquid storage space 4 to prevent the liquid in the liquid storage space 4 from being contaminated by the outside.

[0035] At the same time, the wider sealing line 42 also increases the peripheral strength of the liquid storage bag 1, so that the liquid storage bag 1 can better maintain its shape and further prevent the stored liquid from being contaminated and leaking.

[0036] It can also be seen from the figure that the front side wall 41 of the liquid storage space 4 is provided with a liquid inlet 5 and a liquid outlet 6. The liquid inlet 5 is used to introduce liquid into the liquid storage space 4, and the liquid outlet 6 is used to lead the liquid out of the liquid outlet space 4.

[0037] The liquid outlet 6 may be provided in multiple numbers. For example, two liquid outlets 6 may be provided in the embodiment shown in the figure, so that the liquid can be divided into multiple sub-packages and packaged simultaneously, thereby speeding up the liquid packaging speed and reducing pollution caused by frequent replacement of packaging containers during packaging.

[0038] As shown in the figure, the liquid inlet 5 can be arranged in the middle of the front side wall 41, or near the holding part 2, and the liquid outlet 6 can be arranged at the edge away from the holding part 2. The arrangement position of the liquid inlet 5 and the long distance from the arrangement position of the liquid outlet 6 can make it possible for the liquid to be concentrated on the liquid outlet 6 due to gravity when the liquid storage bag is hung, and will not accumulate at the liquid inlet 5 to cause blockage.

[0039] According to the illustrated example, the liquid inlet 5 includes a joint 52 and a fixed disk 51, and the fixed disk 51 is fixed to the inner side of the front side wall 41, thereby fixing the position of the liquid inlet 5 and increasing the strength of the liquid inlet 5. The joint 52 extends from the front side wall 41 of the fixed disk 51, and the joint 52 is used to connect the liquid storage space 4 with the outside, thereby introducing liquid.

[0040] The shape of the fixing plate 51 is not limited, and can be circular as shown in the figure. The edge of the circular fixing plate has no edges and corners, so as not to damage the front side wall 41; and the circular fixing plate occupies a small area, which is convenient for installation. In other embodiments, the fixing plate can also be other shapes, such as but not limited to oval, polygonal, etc.

[0041] It can also be seen from the figure that the liquid storage space 4 gradually narrows toward the liquid outlet 6 at the edge. The gradually narrowing setting can guide the liquid to concentrate on the liquid outlet 6, so that the liquid in the liquid storage space 4 can be drawn out of the liquid outlet 6 for packaging more quickly.

[0042] Figure 2 The figure is a schematic assembly diagram of an embodiment of the liquid dispensing device of the present utility model.

[0043] As can be seen from the figure, the liquid dispensing device 7 of the present invention comprises a liquid storage bag 1, a liquid inlet pipeline 8 and more than one liquid outlet pipeline 9. The liquid inlet pipeline 8 is connected to the liquid inlet 5 of the liquid storage bag 1, so that the liquid inlet pipeline 8 can introduce liquid into the liquid storage space 4 of the liquid storage bag 1 through the liquid inlet 5.

[0044] Optionally, the liquid inlet pipeline 8, the liquid outlet pipeline 9 and the double Y-shaped tube are platinum-vulcanized silicone tubes, which have strong chemical stability and corrosion resistance, can stably transport chemical products such as culture medium and additives, and have good flexibility and elasticity, can adapt to the connection requirements of different shapes, and a peristaltic pump can be easily installed in the double Y-shaped tube.

[0045] The pipe of the liquid inlet pipeline 8 can be directly connected to the joint 52 of the liquid inlet port 5. Specifically, the pipe of the liquid inlet pipeline 8 is sleeved and clamped on the joint 52. This connection method is convenient and saves costs. In an optional embodiment, a male and female pipe joint can be provided between the pipe of the liquid inlet pipeline 8 and the joint 52 of the liquid inlet port 5.

[0046] The multiple liquid outlet pipelines 9 are directly connected to the multiple liquid outlets 6 of the liquid storage bag 1, respectively, so that the liquid drawn out of the liquid outlet 6 is packaged through the multiple liquid outlet pipelines 9. Specifically, the pipe of the liquid inlet pipeline 8 can be set and tightly connected with the joint 52 of the liquid inlet 5 as described above. Or in other embodiments, the pipe of the liquid inlet pipeline 8 and the liquid inlet 5 are connected by a male and female pipe joint. The multiple liquid outlet pipelines 9 can be set to package at the same time, speed up the packaging efficiency, and thus prevent pollution.

[0047] As shown in the figure, the liquid inlet end 82 of the liquid inlet pipeline 8 is provided with a dust bag 10, and the liquid inlet pipeline 8 includes a sterilizing filter 81. Each liquid outlet pipeline 9 is provided with a flow limiting device 93, a double Y-shaped tube 94 and a filling head 95 in sequence from the liquid outlet 6, and a dust bag 10 is provided at the filling head 95.

[0048] The flow limiting device 93 can be in any form, and can be a flow limiting clamp as shown in the figure, or a liquid stopping clamp to limit the flow rate of the liquid in the pipeline.

[0049] The double Y-shaped tube 94 is used to divide the liquid outlet pipeline 9 into two pipelines and merge the two pipelines into one pipeline. A peristaltic pump (not shown in the figure) is installed between the two pipelines. The peristaltic pump can push the liquid in the two pipelines 9 to flow toward the filling head 95, and the peristaltic pump can control the flow speed of the liquid in the two pipelines to increase the accuracy of the packaging.

[0050] The dustproof bag 10 at the filling head 95 is provided with a sealable opening, which can be directly sealed after the filling is completed to ensure that the filled liquid is not contaminated.

[0051] During packaging, the operator can hang the liquid storage bag 1, and the liquid enters the liquid inlet end 82 through the dustproof bag 10, and passes through the sterilizing filter 81 along the pipeline of the liquid inlet pipeline 8; after being sterilized by the sterilizing filter, it is introduced into the liquid storage space 4 of the storage bag 1 through the liquid inlet 5.

[0052] The liquid in the liquid storage space 4 flows to the liquid outlet 6 of the liquid storage space 4 due to gravity, and is respectively led out from the liquid outlet 6 to multiple liquid outlet pipelines 9, and flows through the two pipelines divided by the double Y-shaped tube 94 after being limited by the flow limiting device 93 of the liquid outlet pipeline 9, and is driven by the peristaltic pump between the two pipelines to merge and flow to the filling head 95, and flows into the dust bag 10 through the filling head 95. After the filling is completed, the dust bag 10 is sealed to complete the liquid packaging.

[0053] It should be noted that the liquid inlet pipeline 8, the liquid outlet pipeline 9 and the liquid storage bag 1 can be integrated into one, and through aseptic irradiation, a sterile liquid filling device is formed, so that the processes of liquid inlet, liquid storage, liquid outlet and filling can be carried out under aseptic conditions. During filling, only the external liquid needs to be connected to the liquid inlet end 82 of the liquid inlet pipeline 8 to complete the subsequent aseptic filling, avoiding the connection at the sterile rear end to prevent contamination.

[0054] The liquid storage bag and liquid dispensing device of the utility model can be disposable products, which are convenient and easy to use and can avoid the trouble of cleaning and the risk of cross contamination.

[0055] The utility model provides a liquid storage bag and a liquid dispensing device including the same, wherein the liquid storage bag has a liquid inlet and a plurality of liquid outlets. The liquid inlet of the liquid storage bag is connected to a liquid inlet pipeline, and the plurality of liquid outlets of the liquid storage bag are respectively connected to a plurality of liquid outlet pipelines, the liquid inlet pipeline, the liquid outlet pipeline and the liquid storage bag are integrated into one, and sterile irradiation is performed to form a sterile liquid dispensing device.

[0056] When the liquid packaging device is subpackaging, the liquid storage bag can be hung through the hanging hole of the holding part of the liquid storage bag, and the liquid to be subpacked can be connected to the liquid inlet pipeline. The liquid is sterilized and filtered through the sterilization filter in the liquid inlet pipeline to form a sterile liquid, and continues to pass through the pipeline of the liquid inlet pipeline and enter the liquid storage space of the liquid storage bag from the liquid inlet. Then, the liquid flows to the liquid outlet of the liquid storage bag due to gravity, and flows out from multiple liquid outlets, respectively flowing to multiple liquid outlet pipelines, and the sterile liquid is filled into multiple dust-proof bags at the filling head according to the peristaltic frequency of the peristaltic pump of the liquid outlet pipeline, thereby completing the subpackaging.
