Description

Technical Field

[0001] The utility model relates to the technical field of blood purification, in particular to a nanometer dialysis membrane that is not easily broken. Background Art

[0002] Hemodialysis is a method of using a dialysis membrane between blood and dialysate to diffuse and remove solutes from the body or replenish solutes into the body, so that large molecules such as blood cells and proteins in the blood are retained, while medium and small molecules such as electrolytes and water are separated from the blood and discharged through the liquid outlet of the shell. The purified blood is then returned to the patient's body to remove metabolic products and toxic substances and correct water and electrolyte imbalances.

[0003] The nanodialysis membrane in existing hemodialyzers is usually designed as a straight tubular structure. The nanodialysis membrane itself has limited toughness. If the straight tubular nanodialysis membrane is too long, it will affect the convenience of taking, placing and installing the nanodialysis membrane. It is impossible to increase the effective length of the nanodialysis membrane while ensuring the convenience of taking, placing and installing the nanodialysis membrane. At the same time, the length of the straight tubular nanodialysis membrane is very limited. If the expected dialysis effect is to be achieved, more nanodialysis membranes need to be used, which in turn affects the cost of each use of the hemodialyzer. Utility Model Content

[0004] The purpose of the present invention is to provide a nanodialysis membrane that is not easily broken, so as to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned objectives, the present invention provides the following technical solution: a nanodialysis membrane that is not easy to break, including a cylindrical silo as an installation carrier, characterized in that: a first liquid inlet pipe connected to the interior of the cylindrical silo is installed on the top of the outer side of the cylindrical silo, a base is installed on the inner bottom of the cylindrical silo, a discharge pipe is installed at the center position of the base, and the bottom end of the discharge pipe extends to the bottom of the cylindrical silo, liquid inlet holes are evenly opened on the top of the outer side of the discharge pipe, a second liquid inlet pipe is installed on the outer side of the cylindrical silo, and a connecting pipe is installed at the bottom end of the second liquid inlet pipe, a plurality of groups of nanodialysis membrane tubes are stacked in sequence from bottom to top in the interior of the cylindrical silo, an output pipe is installed at the center position of the interior of the cylindrical silo, and the top of the output pipe extends to the top of the cylindrical silo, the output pipe is located at the center position of the plurality of groups of nanodialysis membrane tubes, the ends of the plurality of groups of nanodialysis membrane tubes close to the output pipe are all connected to the interior of the output pipe, and the ends of the plurality of groups of nanodialysis membrane tubes away from the output pipe are all connected to the interior of the second liquid inlet pipe.

[0006] Preferably, an annular groove is installed on the top of the liquid inlet hole, and the bottom of the output pipe is embedded in the annular groove.

[0007] Preferably, the nanodialysis membrane tube has a spiral structure, and the height of the spiral coil of the spiral structure is 1 mm to 2 mm.

[0008] Preferably, a funnel groove is provided at the center of the base, the liquid inlet holes are all located inside the funnel groove, and the discharge pipe is located at the center of the funnel groove.

[0009] Preferably, a spiral groove adapted to the nanodialysis membrane tube is provided on the top of the base.

[0010] Preferably, the first liquid inlet pipe and the discharge pipe are both installed with a first connector at one end away from the cylindrical silo, and the access ends of the output pipe and the connecting pipe are both installed with a second connector.

[0012] Beneficial effects

[0013] Compared with the prior art, the present invention provides a nanodialysis membrane that is not easily broken and has the following beneficial effects:

[0014] 1. The utility model designs the nanodialysis membrane tube into a spiral structure, so that the length of each group of nanodialysis membrane tubes can be increased as much as possible according to the needs, and then they can be stacked in a round box. No particularly long box is needed for storage. This can not only meet the hemodialyzer's requirement for the effective dialysis length of the nanodialysis membrane tube, but also reduce the storage space of the nanodialysis membrane tube. Moreover, at the same length, the spiral nanodialysis membrane tube is less likely to crack or break than the straight tubular dialysis membrane.

[0015] 2. The utility model divides the space inside the cylindrical silo into a spiral gap channel through several groups of stacked nanodialysis membrane tubes. After the dialysate is injected into the cylindrical silo through the liquid inlet tube, the dialysate will flow along the spiral gap channel toward the center of the cylindrical silo, thereby increasing the flow path of the dialysate and also improving the effective contact time between the nanodialysis membrane tube and the dialysate. The hemodialyzer can use fewer nanodialysis membrane tubes to achieve the expected dialysis effect, thereby reducing the cost of each use of the hemodialyzer. BRIEF DESCRIPTION OF THE DRAWINGS

Taking over 21, several groups of nanodialysis membrane tubes 14 are stacked in sequence from bottom to top inside the cylindrical silo 10, an output tube 13 is installed at the center position inside the cylindrical silo 10, and the top of the output tube 13 extends to the top of the cylindrical silo 10, the output tube 13 is located at the center position of the several groups of nanodialysis membrane tubes 14, and the ends of the several groups of nanodialysis membrane tubes 14 close to the output tube 13 are all connected to the interior of the output tube 13, and the ends of the several groups of nanodialysis membrane tubes 14 away from the output tube 13 are all connected to the interior of the second liquid inlet pipe 20.

[0028] In this embodiment, an annular groove 17 is installed on the top of the liquid inlet 16, and the bottom of the output pipe 13 is embedded in the annular groove 17, which helps to improve the stability of the output pipe 13 inside the cylindrical silo 10.

[0029] In this embodiment, the nanodialysis membrane tubes 14 are in a spiral structure, and the height of the spiral turns of the spiral structure is 1 mm-2 mm, which helps the dialysate to stably contact the surface of each group of nanodialysis membrane tubes 14 .

[0030] In this embodiment, a funnel groove 18 is opened at the center position of the base 15, the liquid inlet holes 16 are all located inside the funnel groove 18, and the discharge pipe 12 is located at the center position of the funnel groove 18, which helps to make it easier for the dialysate inside the cylindrical silo 10 to enter the discharge pipe 12 through the liquid inlet hole 16.

[0031] In this embodiment, a spiral groove adapted to the nanodialysis membrane tubes 14 is formed on the top of the base 15 , which helps to improve the fit between the bottom group of nanodialysis membrane tubes 14 and the top of the base 15 .

[0032] In this embodiment, the first liquid inlet pipe 11 and the discharge pipe 12 are both equipped with a first connector at one end away from the cylindrical silo 10, and the access ends of the output pipe 13 and the connecting pipe 21 are both equipped with a second connector, which helps to connect the first liquid inlet pipe 11, the discharge pipe 12, the output pipe 13 and the connecting pipe 21 to the corresponding output end and input end of the hemodialyzer respectively.

After that, the blood flows along the guiding spiral of the nanodialysis membrane tube 14, and then all is collected into the interior of the output tube 13, and then discharged from the top of the output tube 13. At the same time, the dialysate is controlled to be injected into the interior of the cylindrical silo 10 through the first liquid inlet pipe 11. The dialysate gradually flows toward the center position of the nanodialysis membrane tube 14 along the spiral gap channel separated by several groups of nanodialysis membrane tubes 14. In the process, the blood inside the nanodialysis membrane tube 14 is purified. After that, the dialysate enters the funnel groove 18 with metabolic products and toxic substances, and then enters the discharge pipe 12 through the liquid inlet hole 16, and is discharged from the discharge pipe 12.
