[0002] A hemoperfusion device is a key medical machine for carrying out hemoperfusion treatment. Hemoperfusion is a blood purification therapy that guides the patient's blood into an extracorporeal circulation system, and non-specifically adsorbs poisons, drugs, and metabolites through the adsorbent in the hemoperfusion device to achieve the effect of removing exogenous or endogenous toxins and metabolites, and then transports the purified blood back into the body. Nowadays, most of the hemoperfusion devices used in the market are cylindrical glass or plastic ones. Due to their easy-to-move shape and fragile materials, the hemoperfusion device is easily damaged during transportation.
[0003] Most of the hemoperfusion devices in the market are made of round glass or plastic products, which occupy a large space and cannot be placed randomly, thus making it inconvenient for handling and placement. For this reason, we propose a hemoperfusion device with a micro-voltage applied thereto. Summary of the Invention
[0004] The purpose of the present invention is to provide a hemoperfusion device with a micro-voltage applied thereto, so as to solve the problems in the above-mentioned background art that most of the hemoperfusion devices in the market are made of round glass or plastic products, which occupy a large space and cannot be placed randomly, thus making it inconvenient for handling and placement.
[0005] To achieve the above purpose, the present invention provides the following technical solution: A hemoperfusion device with a micro-voltage applied thereto, including a tank body. Fixed grooves are provided on the outer walls of both sides of the tank body. An outlet external joint is provided at the bottom end of the tank body.

[0006] Preferably, the anti-backflow mechanism includes a movable column, a spring is provided inside the movable column, and a rubber block is installed at the left end of the movable column.
[0007] Preferably, the two fixed U-shaped columns are symmetrically arranged with respect to the fixing plate. The fixed U-shaped columns are movably arranged in the limiting openings on both sides of the fixing plate through threaded columns, and the fixing grooves are fitted with the fixed U-shaped columns.
[0008] Preferably, a first threaded convex groove is arranged on the outer wall of the first sleeve. The first threaded convex groove is fitted with the first threaded groove. An inlet rotary cover is arranged at the top end of the blood inlet. A second sleeve is arranged inside the inlet rotary cover.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: for the perfusion device with micro-voltage applied, by respectively and movably installing the two fixed U-shaped columns in the limiting openings on both sides of the fixing plate through threaded columns, and then installing it on another perfusion device, and sliding the two fixed U-shaped columns into the fixing grooves on the outer walls on both sides of the tank body, the mutual combination of the two perfusion devices can be realized. Repeating the above operation multiple times can realize the combination of multiple perfusion devices, reducing the occupied space area. Compared with the traditional cylindrical tank body, the flat plate-shaped tank body has better stability, which is beneficial for logistics transportation and placement storage, and greatly reduces the probability of damage during transportation;
[0012] For the perfusion device with micro-voltage applied, before use, open the outlet rotary cover and the inlet rotary cover, insert the two pipes into the interior of the tank body through the blood outlet and the blood inlet respectively.

Detailed implementation manners

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0020] Please refer to Figures 1-5 , the present invention provides a technical solution: a perfusion device with a micro-voltage applied, including a tank body 1. Fixed grooves 2 are provided on the outer walls of both sides of the tank body 1. An outlet external joint 3 is provided at the bottom end of the tank body 1. A bleeding port 4 is provided inside the outlet external joint 3. A first thread groove 6 is provided on the inner wall of the outlet external joint 3. An outlet rotary cover 5 is sleeved on the top end of the outlet external joint 3. An anti-slip sheet 7 is provided on the outer wall of the outlet rotary cover 5. A first sleeve 8 is provided inside the outlet rotary cover 5. An inlet external joint 9 is provided at the top end of the tank body 1. A blood inlet 10 is provided inside the inlet external joint 9. A fixing plate 11 is provided on the outer wall of the tank body 1. Limiting ports 12 are provided on the outer walls of both sides of the fixing plate 11. Fixed U-shaped columns 13 are installed on the outer walls of both sides of the fixing plate 11. A threaded column 14 is provided at the bottom end of the fixed U-shaped column 13. Anti-backflow mechanisms 15 are installed at the positions close to the center of the tank body 1 inside the bleeding port 4 and the blood inlet 10. Filter screens 16 are provided inside the tank body 1 near the bleeding port 4 and the blood inlet 10. An adsorbent 17 is provided inside the tank body 1.
[0021] The anti-backflow mechanism 15 includes a movable column 1501, a spring 1502 is arranged inside the movable column 1501, a rubber block 1503 is installed at the left end of the movable column 1501. Two groups of anti-backflow mechanisms 15 are symmetrically arranged on both sides of the inner wall near the top end of the blood outlet 4, and two groups of anti-backflow mechanisms 15 are symmetrically arranged on both sides of the inner wall near the bottom end of the blood inlet 10. Before use, the outlet rotary cap 5 and the inlet rotary cap are opened, and the two pipes are respectively inserted into the inside of the tank body 1 through the blood outlet 4 and the blood inlet 10. When the pipes reach the blood outlet 4 and the blood inlet 10, they will respectively encounter two symmetric anti-backflow mechanisms 15. When the pipes penetrate deeper into the tank body 1, the two rubber blocks 1503 will be extruded outwards. Under the reaction force of the spring 1502 in the movable column 1501, the two rubber blocks 1503 will be squeezed inwards. Therefore, the blood inlet 10 and the blood outlet 4 are closely attached to the pipes, thereby forming a sealed space, greatly enhancing the tightness of the hemoperfusion device, and being beneficial to preventing blood from flowing out and air and bacteria from entering.
[0022] Two fixed U-shaped columns 13 are symmetrically arranged with respect to the fixed plate 11. The fixed U-shaped columns 13 are movably arranged in the limiting ports 12 on both sides of the fixed plate 11 through threaded columns 14. The fixed groove 2 is fitted with the fixed U-shaped columns 13. A first threaded convex groove is arranged on the outer wall of the first sleeve 8, and the first threaded convex groove is fitted with the first threaded groove 6. The top end of the blood inlet 10 is provided with an inlet rotary cap, and a second sleeve is arranged inside the inlet rotary cap. A second threaded convex groove is arranged on the outer wall of the second sleeve, and a second threaded groove is arranged on the outer wall of the blood inlet 10. The second threaded convex groove is fitted with the second threaded groove. The part of the tank body 1 near the outlet external joint 3 is trapezoidal in shape, the tank body 1 is flat, and the adsorbent 17 is made of resin material. By movably installing the two fixed U-shaped columns 13 in the limiting ports 12 on both sides of the fixed plate 11 through the threaded columns 14 respectively, and then installing them on another hemoperfusion device, and slidingly installing the two fixed U-shaped columns 13 in the fixed grooves 2 on the outer walls on both sides of the tank body 1, the mutual combination of two hemoperfusion devices is realized. Repeating the above operation multiple times can realize the combination of multiple hemoperfusion devices, reducing the occupied space area. Compared with the traditional cylindrical hemoperfusion device, the flat shape of the tank body 1 has better stability, which is beneficial to logistics transportation and placement storage, and greatly reduces the probability of damage during transportation.
[0023] Working principle: For this type of perfusion device with a micro-voltage applied, two fixed U-shaped columns 13 are respectively movably installed in the limiting ports 12 on both sides of the fixing plate 11 through threaded columns 14, and then installed on another perfusion device. The two fixed U-shaped columns 13 are slidably installed in the fixing grooves 2 on the outer walls of both sides of the tank body 1, thereby realizing the mutual combination of the two perfusion devices. Repeating the above operation multiple times can realize the combination of multiple perfusion devices, reducing the occupied space area. Moreover, since the tank body 1 is flat, it has very good stability, which is beneficial for logistics transportation and placement storage, greatly reducing the probability of damage during transportation. For this type of perfusion device with a micro-voltage applied, before use, open the outlet rotary cover 5 and the inlet rotary cover, and insert the two pipes into the interior of the tank body 1 through the blood outlet 4 and the blood inlet 10 respectively. When the pipes reach the blood outlet 4 and the blood inlet 10, they will respectively encounter two anti-backflow mechanisms 15 in a symmetrical state. When the pipes penetrate deeper into the tank body 1, the two rubber blocks 1503 will be extruded outwards. Under the reaction force of the spring 1502 in the movable column 1501, the two rubber blocks 1503 will be squeezed inwards. Therefore, the blood inlet 4 and the blood outlet 10 are in close contact with the pipes, thereby forming a sealed space, greatly enhancing the sealing performance of the perfusion device, which is beneficial for preventing blood from flowing out and air and bacteria from entering.
