[0030] The present embodiment provides a dialysis bag clamping feeding structure 10, please refer to Figures 1-3 which comprises a feeding cylinder 11 and a clamping piece 12. The feeding cylinder 11 has a feeding port 111 and a discharging port 112 in communication, and the feeding cylinder 11 is connected with a cover 113 for closing the feeding port 111. Exemplarily, one end of the cover 113 is connected with the outer wall of the feeding cylinder 11 and can be flipped relative to the feeding cylinder 11, and the cover 113 can be clamped with the feeding cylinder 11, and flipping the cover 113 can open the feeding port 111 or close the discharging port 112.

[0031] The clamping piece 12 comprises a first clamping arm 121 and a second clamping arm 122, one end of the first clamping arm 121 is connected with one end of the second clamping arm 122 and can be flipped relative to each other. Exemplarily, one end of the first clamping arm 121 is connected with one end of the second clamping arm 122 through a connecting piece 123 having a crease. It should be noted that in other embodiments, one end of the first clamping arm 121 can also be connected with one end of the second clamping arm 122 through a hinge or the like, as long as one end of the first clamping arm 121 and one end of the second clamping arm 122 can be flipped relative to each other.

[0032] The other end of the first clamping arm 121 is detachably connected with the other end of the second clamping arm 122. The first clamping arm 121 and the second clamping arm 122 can clamp and fix the dialysis bag to the outer wall of the feeding cylinder 11. For example, the other end of the first clamping arm 121 and the other end of the second clamping arm 122 are detachably connected by buckling, wherein the other end of the first clamping arm 121 has a protrusion, and the other end of the second clamping arm 122 is provided with a buckle capable of buckling with the protrusion to achieve detachable connection.

[0033] The dialysis bag clamping and feeding structure 10 of the present application, in use, first puts the feeding cylinder 11 into the bag opening of the dialysis bag, then clamps and fixes the dialysis bag to the outer wall of the feeding cylinder 11 by the first clamping arm 121 and the second clamping arm 122, and keeps the other end of the first clamping arm 121 and the other end of the second clamping arm 122 connected. Then the material is supplied into the dialysis bag from the feeding port 111 of the feeding cylinder 11, and then the feeding port 111 is closed by the cover 113, and then it is placed in the dialysis container for dialysis treatment. The dialysis bag clamping and feeding structure 10 of the present application not only can clamp the port of the dialysis bag firmly, but also can supply material into the dialysis bag through the feeding cylinder 11, which can avoid the staff directly contacting the dialysis bag for feeding, and after being loaded, it can be directly placed in the dialysis container for dialysis by taking the clamping and feeding structure 10, thereby reducing the probability of material contamination.

[0034] Further, please refer to Figure 4 and Figure 5 The first clamping arm 121 includes a first clamping portion 1211 and a first supporting portion 1212, and the second clamping arm 122 includes a second clamping portion 1221 and a second supporting portion 1222, and the first supporting portion 1212 is connected to both ends of the first clamping portion 1211, and the second supporting portion 1222 is connected to both ends of the second clamping portion 1221. The first clamping portion 1211 has a first clamping surface, and the second clamping portion 1221 has a second clamping surface, and when the first clamping portion 1211 and the second clamping portion 1221 clamp and fix the dialysis bag to the outer wall of the feeding cylinder 11, the first clamping surface and the second clamping surface are in abutment with the feeding cylinder 11. For example, the overall shape of the cross section of the feeding cylinder 11 is oval, and the first clamping surface and the second clamping surface are also arc-shaped, and when the first clamping portion 1211 and the second clamping portion 1221 are clamped to the outer wall of the feeding cylinder 11, the first clamping surface and the second clamping surface are in abutment with the outer wall of the feeding cylinder 11, thereby facilitating better clamping and fixing of the dialysis bag to the clamping and feeding structure 10.

[0035] In addition, the first support part 1212 and the second support part 1222 are engaged with each other, so that the first clamping part 1211 and the second clamping part 1221 can clamp the dialysis bag more tightly, and the dialysis bag is less likely to fall off the clamping feeding structure 10. For example, one of the first support part 1212 and the second support part 1222 is provided with a protrusion 131, and the other is provided with a groove 132, and the protrusion 131 and the groove 132 can be engaged. For example, the first support part 1212 is provided with the protrusion 131, and the second support part 1222 is provided with the groove 132; or the first support part 1212 is provided with the groove 132, and the second support part 1222 is provided with the protrusion 131. By engaging the protrusion 131 and the groove 132, the first support part 1212 and the second support part 1222 can be connected more tightly.

[0036] Further, the outer wall of the feeding barrel 11 has a first limiting convex ring 114 and a second limiting convex ring 115 arranged at intervals in the circumferential direction, and the first limiting convex ring 114 and the second limiting convex ring 115 can limit the first clamping part 1211 and the second clamping part 1221 between the first limiting convex ring 114 and the second limiting convex ring 115.

[0037] When the first clamping part 1211 and the second clamping part 1221 clamp the dialysis bag on the outer wall of the feeding barrel 11, due to the limiting effect of the first limiting convex ring 114 and the second limiting convex ring 115, the first clamping part 1211 and the second clamping part 1221 can be prevented from sliding downward, so that the dialysis bag can be better fixed on the outer wall of the feeding barrel 11.

[0038] Further, the outer wall of the feeding barrel 11 is provided with a snap ring 116 in the circumferential direction, the snap ring 116 is arranged between the first limiting convex ring 114 and the second limiting convex ring 115, and the height of the snap ring 116 is lower than the height of the first limiting convex ring 114 and the second limiting convex ring 115. The first clamping part 1211 has a first limiting clamping groove 1211a, and the second clamping part 1221 has a second limiting clamping groove 1221a, and the snap ring 116 can be clamped in the first limiting clamping groove 1211a and the second limiting clamping groove 1221a. For example, the first limiting clamping groove 1211a is formed by a first limiting plate 12111 arranged at the edge of the first clamping part 1211 and a second limiting plate 12112 arranged at intervals with the first limiting plate 12111; and the second limiting clamping groove 1221a is formed by a third limiting plate 12211 arranged at the edge of the second clamping part 1221 and a fourth limiting plate 12212 arranged at intervals with the third limiting plate 12211.

[0039] When the first clamping part 1211 and the second clamping part 1221 clamp the dialysis bag on the outer wall of the feeding cylinder 11, the snap ring 116 can be clamped in the first limiting clamping groove 1211a of the first clamping part 1211 and the second limiting clamping groove 1221a of the second clamping part 1221, so that the first clamping part 1211 and the second clamping part 1221 are more firmly connected with the feeding cylinder 11, and the dialysis bag is better fixed on the outer wall of the feeding cylinder 11.

[0040] The embodiment also provides a dialysis device, which comprises a dialysis bag and the dialysis bag clamping feeding structure 10 described above, and the first clamping arm 121 and the second clamping arm 122 clamp and fix the dialysis bag on the outer wall of the feeding cylinder 11.

[0041] In summary, the dialysis bag clamping feeding structure 10 of the present application can clamp and fix the dialysis bag on the outer wall of the feeding cylinder 11 through the first clamping arm 121 and the second clamping arm 122, which not only can firmly clamp the port of the dialysis bag, but also can feed the dialysis bag through the feeding cylinder 11, can avoid the staff directly contacting the dialysis bag for feeding, and can directly place the clamping feeding structure 10 in the dialysis container for dialysis after being filled, thereby reducing the probability of material pollution.

[0042] The above is only the preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
