Description

Technical Field

[0001] The utility model relates to the field of resin cleaning, in particular to a blood perfusion-grade resin particle dispersion cleaning device. Background Art

[0002] Hemoperfusion refers to the process of blood being circulated extracorporeally through an adsorbent device with a broad-spectrum detoxification effect or fixed specific ligands to remove endogenous or exogenous pathogenic substances from the blood to achieve the purpose of blood purification. Hemoperfusion is currently mainly limited to adsorption, so it is also called blood adsorption. Hemoperfusion can effectively remove creatinine, uric acid, middle-molecular substances, phenols, guanidines, indoles, organic acids and various drugs in the blood.

[0003] Hemoperfusion-grade resin is a macroporous neutral resin, a spherical material with high specific surface area and high porosity. However, it is often doped with various impurities, including microparticles and microscopic foreign matter. The average resin diameter is generally 0.45-1.25 mm, while the diameter of doped microparticles is generally less than 20 μm. Microscopic foreign matter, which is difficult to detect with the naked eye, has an average diameter of less than 0.2 mm.

[0004] The resin used in hemoperfusion needs to be cleaned beforehand. However, the cleaning equipment for hemoperfusion-grade resin currently requires multiple water changes and flushing during use. This means that a large amount of cleaning water is consumed during injection, resulting in high resin cleaning costs and low cleaning efficiency, resulting in poor resin cleaning effects and affecting the safety of resin use.

The buoyancy of the water flow impacts the medical resin so that it is completely suspended. In addition, the multi-channel water inlet at the bottom of the cleaning barrel ensures that the water flow impact force of each part of the internal tube is the same. The medical resin is heavier than microparticles and microforeign matter and requires a greater buoyancy than microparticles and microforeign matter. When the blood perfusion-grade resin is in a suspended state, the microparticles and microforeign matter can flow out of the water outlet with the impact of the water flow. The cleaning water is continuously supplied to the bottom, and the microparticles and microforeign matter in the medical resin are continuously separated and discharged with the water flow.

[0031] The utility model utilizes a water inlet assembly to continuously supply cleaning water from the bottom of the cleaning barrel into the interior thereof. The water flow impact buoyancy causes the medical resin to be completely suspended. The multi-channel water inlet at the bottom of the cleaning barrel ensures that the water flow impact force at each part of the circular channel is equal. The medical resin has a larger mass than microparticles and microforeign matter and requires a larger buoyancy force than the microparticles and microforeign matter. When the hemoperfusion-grade resin is in a suspended state, the microparticles and microforeign matter can flow out of the water outlet with the impact of the water flow.

[0043] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0044] Figures 1 to 5 The figure shows a schematic structural diagram of an embodiment of the hemoperfusion-grade resin particle dispersion cleaning device of the present invention. The hemoperfusion-grade resin particle dispersion cleaning device comprises a cleaning barrel 1, which is used to provide a cleaning space for the hemoperfusion-grade resin particle dispersion cleaning;

[0045] A water inlet assembly 2 is connected to the bottom of the cleaning bucket 1 and is used to pump cleaning water into the cleaning bucket 1;

[0046] A drain pipe 3 is provided on the side of the cleaning bucket 1 , and the drain pipe 3 is used to discharge the substances in the cleaning bucket 1 .

[0047] In the present technical solution, the water inlet assembly 2 is utilized to continuously supply cleaning water from the bottom of the cleaning barrel 1 into the interior thereof. The buoyancy of the water flow impacts the entire medical resin in suspension, and the multi-channel water inlet at the bottom of the cleaning barrel 1 ensures that the water flow impact force of each part of the internal tube is equal. The medical resin is heavier than microparticles and microforeign matter and requires a greater buoyancy than microparticles and microforeign matter. When the blood perfusion-grade resin is in a suspended state, the microparticles and microforeign matter can flow out of the water outlet with the impact of the water flow. The cleaning water is continuously supplied to the bottom, and the microparticles and microforeign matter in the medical resin are continuously separated and discharged with the water flow.

[0048] That is, when in use, the porous parts continuously supply water, and particles and micro foreign matter are continuously separated and removed.

[0049] The cleaning bucket 1 includes a drainage section 11, a hollow section 12 and a water inlet section 13. The cleaning bucket 1 is divided into the drainage section 11, the hollow section 12 and the water inlet section 13 from top to bottom.

[0050] The drainage section 11 and the hollow section 12 , as well as the hollow section 12 and the water inlet section 13 , are detachably connected via connection components 14 .

[0051] In this technical solution, the drainage section 11 , the hollow section 12 and the water inlet section 13 can be disassembled and assembled with each other through the connecting assembly 14 .

[0052] The water inlet assembly 2 includes a water inlet plate 21 and a plurality of water inlet pipes 22. The water inlet plate 21 is connected to the bottom of the water inlet section 13.

[0053] The water inlet plate 21 is provided with a plurality of evenly distributed water inlet holes 221. A plurality of water inlet pipes 22 are drawn out from the water outlet of the peristaltic pump 23 and connected to the water inlet holes 221. Furthermore, a filter 222 is installed in each water inlet hole 221 to intercept particles.

[0054] The 021 is a stainless steel plate or a plate made of other materials.

[0055] The water inlet pipe 22 is segmented: the lower part is threaded, and the upper part is a small hole for sealing and adding a filter.

[0056] For example, the water inlet plate 21 is a stainless steel plate with a diameter of 15 to 18 cm and a thickness of 5 to 10 cm;

[0057] The drainage section 11 is a cylinder with a diameter of 15-18 cm and a height of 20-25 cm, and the hollow section 12 is a cylinder with a diameter of 15-18 cm and a height of 5-10 cm.

[0058] In this technical solution, the water inlet assembly 2 can be used to continuously feed cleaning water from the bottom of the cleaning barrel 1 into the interior thereof.

[0059] In this technical solution, the cleaning water can be pumped into the cleaning barrel 1 using a peristaltic pump 23 .

[0060] The water inlet pipe 22 can ensure that the flow rate of water entering the cleaning tub 1 is uniform.

[0061] During use, the liquid-perfused grade resin is placed in the upper space of the cleaning bucket 1, and then the peristaltic pump 23 continuously and evenly delivers cleaning water into the cleaning bucket 1 through the water inlet pipe 22 and the water inlet hole 221. At this time, the liquid-perfused grade resin is completely suspended, and the suspension position is lower than the drain port 53. Then, the particles and micro-foreign matter are discharged from the drain port 53 and the drain pipe 3 with the water flow. This continues for 6-8 minutes, and the particles and micro-foreign matter in the liquid-perfused grade resin can be basically removed.

[0062] It is worth noting that the volume of the liquid-perfusion-grade resin in the cleaning barrel 1 is less than one-third of the volume of the cleaning barrel 1 .

[0063] The pumping speed of the peristaltic pump 23 is 40-70 ml / min.

[0064] The drainage section 11 is connected to the drainage pipe 3 through the drainage assembly 5. The drainage assembly 5 includes a filter frame 51 and a centralizing frame 52. The filter frame 51 is connected to the inner wall of the drainage section 11, and the centralizing frame 52 is connected to the outer side of the drainage section 11.

[0065] The cleaning bucket 1 is provided with a plurality of drain ports 53 , through which the filter frame 51 and the central frame 52 are connected;

[0066] The outer side of the centralizing frame 52 is connected to a drain pipe 3 .

[0067] In this technical solution, the drainage component 5 can be used to filter the substances discharged from the cleaning barrel 1 to prevent the resin from being carried out of the cleaning barrel 1.

[0068] The drainage assembly 5 further includes a driving source 54 , which is mounted on the top of the drainage section 11 ;

[0069] The output end of the driving source 54 is connected to a rotating plate 55 , and the bottom of the rotating plate 55 is connected to a plurality of connecting columns 56 ;

[0070] One end of the connecting post 56 away from the rotating plate 55 is connected to a mounting plate 57 , and one side of the mounting plate 57 is connected to a cleaning brush 58 , which is in contact with the filter frame 51 .

[0071] In this technical solution, the rotating cleaning brush 58 can be used to clean the centralizing frame 52 to prevent the centralizing frame 52 from being blocked and affecting its use.

[0072] A fixed rail 59 is connected to the inner wall of the top surface of the drainage section 11 , and a rail groove is opened on the top surface of the rotating plate 55 . The fixed rail 59 is slidably connected to the rotating plate 55 through the rail groove.

[0073] In this technical solution, the fixed track 59 can be used to limit the rotation track of the rotating plate 55.

[0074] When the cleaning barrel 1 is drained, the blood perfusion grade resin is filtered through the filter frame 51, and then the particles, micro foreign matter and water pass through the filter frame 51, and then enter the collection frame 52 through the drain port 53, and finally discharged through the drain pipe 3.

[0075] During use, the driving source 54 is used to drive the rotating plate 55 to rotate around the fixed track 59, thereby driving the connecting column 56 to rotate, and then driving the mounting plate 57 and the cleaning brush 58 to rotate. The rotating cleaning brush 58 can be used to clean the filter frame 51 to prevent the filter frame 51 from being blocked and affecting its use.

[0076] The connection assembly 14 is a quick-connect chuck connection, a threaded connection, or other detachable and well-sealed connection methods.

[0077] The driving source 54 is a motor or other equipment that can output rotational kinetic energy.

[0078] Although specific embodiments of the present invention have been described above, those skilled in the art will appreciate that these are merely illustrative and that the scope of protection of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, and such changes and modifications are intended to fall within the scope of protection of the present invention.
