[0002] Blood purification is also called dialysis in daily life. Its meaning is: the blood of patients is led out of the body and passes through a purification device to remove certain pathogenic substances in the blood, purify the blood and achieve the purpose of treating diseases. Blood purification should include hemodialysis, hemofiltration, hemoperfusion, plasma exchange, immunoadsorption, etc. During the dialysis purification process, some impurities and metabolites in the blood are filtered, and the filtered ones are called waste liquid and need to be collected and treated. A special medical collection device is needed for collection. With the development of modern medical technology, the types and functions of such collection devices are gradually increasing. However, the existing blood purification waste liquid collection device collects waste liquid by using a disposable collection bag, which is convenient for disposal and does not require cleaning. When the disposable collection bag is full of waste liquid, its volume will expand, which will squeeze and block the inside of the collection device, making it difficult to remove. At the same time, it is very difficult to operate for the staff to disconnect the connection end of the collection device before taking it out, which reduces the convenience of the device. To solve this problem, the present design proposes a blood purification waste liquid collection device. SUMMARY

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. 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.

[0018] Please refer to Figures 1-5 The present application provides a technical solution: a blood purification waste liquid collecting device, comprising a support frame 1 and a waste liquid collecting mechanism 2 installed on the upper end of the support frame 1.

[0019] The waste liquid collecting mechanism 2 comprises collecting barrels 201 inserted and installed at both ends of the top of the support frame 1. One side of the top of the support frame 1 is rotatably connected with a fixing frame 202. Both ends of one side of the fixing frame 202 are fixedly provided with arc-shaped clamping plates 203. The top of each of the two collecting barrels 201 and the top of each of the two arc-shaped clamping plates 203 are fixedly provided with arc-shaped threaded rings 204. The inner walls of the two collecting barrels 201 are each inserted and installed with a waste liquid bag 205. The inner walls of the two collecting barrels 201 are each installed with a butt joint pipe 206. One end of each of the two waste liquid bags 205 is inserted and connected with a first connecting pipe 207. The outer walls between the two collecting barrels 201 are inserted and connected with a second connecting pipe 208. The outer walls of the four arc-shaped threaded rings 204 are threadedly connected with two protective covers 209.

[0020] In use, after the protective cover 209 is unscrewed from the arc-shaped threaded ring 204, the fixed frame 202 is rotated to rotate on the support frame 1, and then the arc-shaped clamping plate 203 on one side of the collection barrel 201 is unscrewed from the collection barrel 201, so that the upper opening of the collection barrel 201 is increased, and then the first connecting pipe 207 connected with the butt joint pipe 206 is unscrewed, and the waste liquid bag 205 can be easily taken out of the collection barrel 201 for disposal. When replacing the new waste liquid bag 205, the first connecting pipe 207 is screwed with the butt joint pipe 206, the fixed frame 202 is rotated to be clamped on the top of the support frame 1, and the arc-shaped clamping plate 203 is attached to the upper side of the collection barrel 201, so that the complete collection barrel 201 is formed, and finally the protective cover 209 is screwed on to fix the entire collection device, so that it cannot be opened by itself during collection of waste liquid. The design makes the disposable waste liquid bag 205 easy to be taken out after being filled, and the waste liquid will not flow out when the waste liquid bag 205 is torn. At the same time, the operation of disconnecting the connection area between the waste liquid bag 205 and the collection barrel 201 is more convenient, thereby improving the convenience of using the device.

[0021] Further, the inner walls of the two first connecting pipes 207 at one end are respectively screwed with the outer walls of the two butt joint pipes 206, and the inner walls of the two second connecting pipes 208 at both ends are respectively communicated with the inner walls of the two butt joint pipes 206. After the waste liquid bag 205 is connected with the butt joint pipe 206 through the first connecting pipe 207, the waste liquid can be introduced into the waste liquid bag 205 through the second connecting pipe 208. When introducing, the third end of the second connecting pipe 208 directly connects with the waste liquid introduction area, so that the waste liquid flows into the first connecting pipe 207 through the other two ends of the second connecting pipe 208, and finally enters the waste liquid bag 205. The waste liquid bag 205 is a disposable product.

[0022] Further, a first handle 3 is fixedly arranged at the edge of one side of the top of the fixed frame 202, and a limiting ring 4 is fixedly arranged at the top of each side of the support frame 1. The bottoms of the outer walls of the two collection barrels 201 are respectively connected with the inner walls of the two limiting rings 4. After a long time of use, some waste liquid may drop on the inner walls of the collection barrels 201, which can be pulled out of the limiting ring 4 for cleaning after a period of use.

[0023] Further, a clamping hole 5 is formed at the lower edge of each side of the outer wall of the two collection barrels 201, and a clasp 6 is connected with the inner wall of each side of the two limiting rings 4. The outer wall of one end of the two clasps 6 is respectively connected with the inner wall of the two clamping holes 5.

[0024] The inner wall of the two limiting rings 4 is fixed with a spring 7 at both ends, and one end of the two springs 7 is fixedly connected with one side of the two buckles 6 respectively, and when the collecting barrel 201 is fixed, it is clamped into the limiting ring 4, so that the buckle 6 is clamped into the clamping hole 5 under the extrusion of the spring 7, thereby fixing the collecting barrel 201, so that it is not easy to fall off when collecting waste liquid, and it is also convenient for disassembly and cleaning later;

[0025] Further, the top of the support frame 1 is fixedly provided with a second handle 8, and the four corners of the bottom of the support frame 1 are fixedly provided with universal wheels 9, so as to facilitate the movement of the whole waste liquid collecting device through the second handle 8 and the universal wheels 9.
