Description

Technical Field

[0001] The present application relates to the technical field of filling equipment, and in particular to a collagen filling tank and filling equipment. Background Art

[0002] After the collagen is prepared, it needs to be filled into a syringe to obtain the final product. The filling is usually carried out in a collagen filling tank. A filling port is provided on the lower surface of the bottom plate of the collagen filling tank. The bottom plate of the collagen filling tank is provided with a liquid storage cavity. The material in the liquid storage cavity can enter the syringe under the action of a pumping mechanism. However, the inventors of the present application found that when filling, when a small amount of material is left at the bottom of the collagen filling tank, it is easy to cause bubbles in the product during the filling process. The reason is that the inner diameter of the liquid storage cavity is much larger than the diameter of the filling port, and collagen has a certain viscosity. As a result, during the process of pumping collagen, the collagen corresponding to the top of the filling port flows to the syringe, while the collagen on the side of the filling port does not have time to flow to the filling port, resulting in the gas in the collagen filling tank entering the syringe, forming bubbles in the collagen filled in the syringe. Utility Model Content

[0003] The present application provides a collagen filling tank and filling equipment, which can improve the problem of easy generation of bubbles in filled products.

[0004] This application is implemented as follows:

[0005] In the first aspect, the present application provides a collagen filling tank, which includes a shell body, the shell body having a shell bottom plate, the lower surface of the shell bottom plate being provided with a filling port, and the filling port being used to install a filling syringe; the shell bottom plate is provided with a plurality of liquid storage cavities, the liquid storage cavities passing through the upper surface of the shell bottom plate and correspondingly connected to the filling ports, the inner diameter of the liquid storage cavity being equal to or smaller than the inner diameter of the filling port, and the volume of the liquid storage cavity being greater than or equal to the volume of the filling syringe.

[0006] In a possible implementation manner, the volume of the liquid storage chamber is 1 to 3 times the volume of the filling syringe.

[0007] In a possible implementation manner, the ratio of the inner diameter of the liquid storage chamber to the inner diameter of the filling syringe is 1:1-2.

[0008] In a possible implementation manner, the ratio of the height to the inner diameter of the liquid storage cavity is 4-10:1.

[0009] In a possible implementation manner, the height of the liquid storage cavity is 40-60 mm, and the inner diameter of the liquid storage cavity is 5-10 mm.

[0010] In a possible implementation manner, the volume of the liquid storage cavity is such that the inner diameter of the filling port is 5 to 10 mm.

[0011] In a possible embodiment, the inner diameter of the liquid storage cavity is consistent from top to bottom, and the liquid storage cavity is cylindrical.

[0012] In a second aspect, the present application provides a filling device, comprising a filling syringe, a pumping mechanism and the collagen filling tank described in the first aspect, wherein the inlet of the pumping mechanism is connected to the filling port through a hose, and the filling syringe is connected to the outlet of the pumping mechanism through a hose.

[0013] The embodiments of the present application have at least the following beneficial effects:

[0014] The volume of the collagen filling tank's liquid storage chamber is greater than or equal to the volume of the filling syringe. During filling, this ensures that all material entering the filling syringe originates from the liquid storage chamber. The inner diameter of the liquid storage chamber is equal to or smaller than the inner diameter of the filling port. During filling, material directly above the filling port flows into the syringe, while material is absent from the liquid storage chamber to the sides of the filling port. This reduces the risk of gas within the collagen filling tank entering the syringe, thereby alleviating the problem of bubbles easily forming in the filled product. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] It should also be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "disposed," "installed," and "connected" should be understood broadly.

Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances. Example

[0024] This embodiment provides a collagen filling tank 10, which includes a housing 11 having a bottom plate 111. A lower surface 1113 of the bottom plate 111 is provided with a plurality of filling ports 1111, which are used to receive filling syringes 20. The bottom plate 111 defines a plurality of liquid storage chambers 1114, which extend through an upper surface 1112 of the bottom plate 111 and communicate with the filling ports 1111 in a one-to-one correspondence. The inner diameter of each liquid storage chamber 1114 is equal to or smaller than the inner diameter of the filling ports 1111, and the volume of each liquid storage chamber 1114 is greater than or equal to the volume of the filling syringe 20. Preferably, the inner diameter of each liquid storage chamber 1114 is equal to the inner diameter of the filling port 1111.

[0025] In the collagen filling tank 10 of the present application, the volume of the liquid storage chamber 1114 is greater than or equal to the volume of the filling syringe 20. When a small amount of material remains at the bottom of the collagen filling tank 10, the material is entirely located in the liquid storage chamber 1114. During filling, the material (e.g., collagen solution) entering the filling syringe 20 is ensured to originate entirely from the liquid storage chamber 1114. During filling, the material is pumped into the filling syringe 20 by a pumping mechanism 30. The pumping mechanism 30 can be a peristaltic pump, which controls the amount pumped into the filling syringe 20 each time. Multiple liquid storage chambers 1114 and filling ports 1111 are provided, enabling simultaneous filling of multiple filling syringes 20. Exemplarily, the volume of the liquid storage chamber 1114 is 1 to 3 times the volume of the filling syringe 20, for example, 1, 2, or 3 times the volume of the filling syringe 20. If the volume of the liquid storage chamber 1114 is too large, the liquid storage chamber 1114 will occupy too much area of the shell bottom plate 111, resulting in a smaller number of liquid storage chambers 1114. However, setting the volume of the liquid storage chamber 1114 to 1 to 3 times the volume of the filling syringe 20 can not only fully ensure the liquid storage capacity of the liquid storage chamber 1114, but also allow for the arrangement of more liquid storage chambers 1114 to be equipped with more filling syringes 20 for filling. It should be noted that the collagen filling tube of the present application can be used not only to contain collagen, but also to contain other materials, such as sodium hyaluronate.

[0026] The inner diameter of liquid storage chamber 1114 is equal to or smaller than the inner diameter of filling port 1111. During filling, material directly above filling port 1111 flows into the syringe, while material is absent from the liquid storage chamber 1114 to the sides of filling port 1111. This prevents gas within collagen filling tank 10 from entering the syringe, thereby alleviating the problem of bubbles easily forming in the filled product. For example, the ratio of the inner diameter of liquid storage chamber 1114 to the inner diameter of filling syringe 20 is 1:1-2, such as 1:1, 1:1.5, or 1:2.

[0027] Optionally, the height of the liquid storage chamber 1114 is 40-60 mm, and the inner diameter of the liquid storage chamber 1114 is 5-10 mm. For example, the height of the liquid storage chamber 1114 is any one of 40 mm, 45 mm, 50 mm, 55 mm, and 60 mm, or a value between any two thereof. Optionally, the inner diameter of the liquid storage chamber 1114 is any one of 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, and 10 mm, or a value between any two thereof.

[0028] Optionally, the inner diameter of the filling port 1111 is 5-10 mm, for example, any one of 5 mm, 6 mm, 7 mm, 8 mm, 9 mm and 10 mm, or a value between any two of them.

[0029] If the liquid storage chamber 1114 is too small relative to the inner diameter of the filling syringe 20, the suction effect will be weakened when using the same suction device, and it will be difficult to easily draw the material in the liquid storage chamber 1114 into the filling syringe 20 during filling. In this embodiment, the ratio of the inner diameter of the liquid storage chamber 1114 to the inner diameter of the filling syringe 20 is 1:1-2, which makes it relatively easy to draw the material from the liquid storage chamber 1114 into the filling syringe 20 through suction.

[0030] Among them, the inner diameter of the liquid storage chamber 1114 is consistent from top to bottom, and the liquid storage chamber 1114 is cylindrical as a whole. In other embodiments, the inner diameter of the liquid storage chamber 1114 can also increase from top to bottom. When the pumping mechanism 30 is used for suction, the suction effect of the lower end of the liquid storage chamber 1114 is stronger, which is conducive to smoothly sucking the material in the liquid storage chamber 1114 into the filling syringe 20. If the inner diameter of the liquid storage chamber 1114 decreases from top to bottom, the suction effect of the lower end of the liquid storage chamber 1114 will be relatively weakened. It is understandable that the liquid storage chamber 1114 as a whole can also be other shapes, such as a quadrangular prism, a pentagonal prism or a hexagonal prism.

[0031] Optionally, the ratio of the inner diameter of the liquid storage chamber 1114 to the inner diameter of the filling syringe 20 is 4 to 10:1. For example, the ratio of the inner diameter of the liquid storage chamber 1114 to the inner diameter of the filling syringe 20 is any one of 4:1, 5:1, 6:1, 7:1, 8:1, 9:1, and 10:1, or a value between any two thereof.

[0032] This embodiment also provides a filling device 100, which includes a filling syringe 20, a pumping mechanism 30 and the collagen filling tank 10 of the first aspect. The inlet of the pumping mechanism 30 is connected to the filling port through a hose, and the filling syringe 20 is connected to the outlet of the pumping mechanism 30 through a hose.

[0033] In summary, the volume of the liquid storage chamber 1114 of the collagen filling tank 10 and filling equipment 100 of the present application is greater than or equal to the volume of the filling syringe 20. During filling, it can be ensured that all the material entering the filling syringe 20 comes from the liquid storage chamber 1114. The inner diameter of the liquid storage chamber 1114 is equal to or smaller than the inner diameter of the filling port 1111. During filling, the material corresponding to the filling port 1111 directly above the filling port 1111 flows into the syringe, while no material exists at the position of the liquid storage chamber 1114 on the side of the filling port 1111. This makes it less likely that gas in the collagen filling tank 10 will enter the syringe, thereby improving the problem of bubbles easily generated in the filled product.

[0034] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
