DETAILED DESCRIPTION

[0023] The embodiments of the present invention are described in detail below. Figures 1 to 3 An embodiment of the utility model provides a device for filling a dialysis bag with a high-viscosity product, including a storage barrel 100, wherein a storage chamber 111 for storing a high-viscosity product such as a polysaccharide gel is provided inside the storage barrel 100, a piston portion 200 is installed in the storage chamber 111, a discharge portion 300 is provided at the bottom of the storage barrel 100, and the discharge portion 300 is provided with a discharge port 310 connected to the storage chamber 111; the discharge portion 300 can extend into the dialysis bag, and the piston portion 200 can move toward the discharge port 310 in the storage chamber 111 to squeeze the high-viscosity product in the storage chamber 111 into the dialysis bag through the discharge port 310.

[0024] This device uses a storage barrel 100 to store high-viscosity products such as polysaccharide gel products. When bagging, the discharge portion 300 can be extended into the dialysis bag, and then the piston portion 200 can be pushed toward the discharge port 310 to squeeze the high-viscosity product into the dialysis bag through the discharge port 310. By using this device to bag products, the dialysis bag can be filled with products at one time. It is not only convenient to operate and has high filling efficiency, but also can avoid long exposure time of the product, and can reduce contamination of the product. Since the discharge portion 300 can be directly extended into the dialysis bag and then the product is filled, it can also prevent the product from sticking to the middle or edge of the dialysis bag, avoid the problem of inefficiency and product contamination caused by repeated filling, and there is no residue at the mouth of the dialysis bag, which can also prevent the product from sticking to the hands.

[0025] Further, the piston part 200 can be pushed manually or pneumatically. When the piston part 200 is pushed pneumatically, the device further includes a compressed air pipe 400 and a compressed air valve 500. The top of the storage barrel 100 is provided with an air inlet 131, and the two ends of the compressed air pipe 400 are respectively connected to the air inlet 131 and the compressed air valve 500; the compressed air valve 500 can press air into the storage barrel 100 to push the piston part 200 toward the discharge port 310. After the discharge part 300 extends into the inside of the dialysis bag, the compressed air valve 500 can be used to press air into the storage barrel 100, so as to push and squeeze the piston part 200 in the direction of the discharge port 310, and finally squeeze the product in the storage cavity 111 into the dialysis bag through the discharge port 310. In some embodiments, the compressed air valve 500 is a valve that can adjust the control airflow so as to adjust to a suitable filling speed. The device can realize automatic filling of products, improve filling efficiency, can be applied to mass production, and can increase the volume of the storage chamber 111 to store more products to realize continuous filling.

[0026] Further, refer to Figure 3 and Figure 4 The top of the piston part 200 is provided with a groove 210 which is concave toward the discharge port 310. When the compressed air valve 500 presses air into the storage barrel 100, the groove 210 can accommodate and carry more air, increase the contact area between the piston part 200 and the airflow, and make the air gather at the groove 210 to squeeze the piston part 200, so as to better push the piston part 200 to move toward the discharge port 310. Furthermore, the groove 210 is an arc-shaped groove with a larger upper part and a smaller lower part, and the bottom of the piston part 200 has an arc-shaped surface 220 with a larger upper part and a smaller lower part, which can not only carry more airflow and increase the thrust of the piston part 200, but also reduce the friction between the piston part 200 and the side wall of the storage chamber 111, and also make the bottom of the piston part 200 present a shape similar to a bullet head, so that the movement of the piston part 200 is smoother and the product is better squeezed out from the discharge port 310.

[0027] Further, refer to Figure 2 and Figure 3The storage barrel 100 includes an inner barrel 110, an outer barrel 120 and a cover 130. The outer barrel 120 is sleeved on the outside of the inner barrel 110, and the cover 130 is sleeved on the top of the outer barrel 120. The air inlet 131 is opened on the cover 130, the storage cavity 111 is opened in the inner barrel 110, and the discharge part 300 is connected to the bottom of the inner barrel 110 and extends from the bottom of the outer barrel 120. When storing materials, the polysaccharide gel product can be loaded into the inner barrel 110 at one time, and the piston part 200 is loaded at the rear end of the inner barrel 110, the inner barrel 110 is placed in the outer barrel 120, the discharge part 300 is installed at the bottom of the inner barrel 110, and the cover 130 is installed on the top of the outer barrel 120. When loading materials, the discharge part 300 is extended into the dialysis bag, and the compressed air valve 500 is opened to squeeze the product into the dialysis bag. The storage barrel 100 adopts a split design of the inner barrel 110 and the outer barrel 120, and can be equipped with multiple inner barrels 110. When the current inner barrel 110 is being filled, the next inner barrel 110 can be loaded with glue for standby use. After the product in the current inner barrel 110 is filled, the empty inner barrel 110 can be removed and a new inner barrel 110 can be installed to achieve continuous filling operations.

[0028] Furthermore, the cover 130 is threadedly connected to the top of the outer barrel 120, and the cover 130 can be installed and opened by tightening or unscrewing. Figure 5 The outer periphery of the cover 130 is provided with ribs 132 extending in the axial direction. There are multiple ribs 132 distributed along the circumference of the cover 130, which can achieve anti-slip, so as to facilitate the installation and opening of the cover 130. Figure 6 The first end of the discharge portion 300 is threadedly connected to the bottom of the storage barrel 100, which can facilitate the installation and disassembly of the discharge portion 300. The second end of the discharge portion 300 is a flat expansion structure, such as a duckbill structure, which can facilitate the extension of the discharge portion 300 into the dialysis bag and facilitate the discharge. In addition, after the loading is completed, the flat structure can also be easily pressed from the outside to cut off the gel flow, so that the discharge portion 300 can be cleanly taken out of the dialysis bag without sticking.
