Problems solved by technology

The dialysis process has the following problems: (1) The blood is separated from the body, which may cause a sharp decrease or increase in the blood volume of the patient, resulting in unstable blood pressure and even death; (2) The extracorporeal dialysis process usually only lasts for several hours , unable to continuously, long-term, and stably perform hemodialysis for patients; (3) The extracorporeal dialysis equipment is huge and difficult to transport, and the patient needs to be transported to the dialysis room, or the huge extracorporeal dialysis machine is transported to the patient's bedside, which increases the difficulty of treatment ; (4) The instrument is expensive, reaching hundreds of thousands or even millions

Embodiment 1

[0040] Such as Figure 1-4 As shown, this embodiment provides a hemodialysis device, which includes a dialysis tube 1, a connection part 2 connected to the dialysis tube 1, a fixing part 3 provided between the dialysis tube 1 and the connection part 2, a dialysate container 4, Peristaltic pump 5 and waste liquid tank 6. The dialysate container 4 is connected to the connection part through a liquid inlet tube 41, the peristaltic pump 5 is connected to the connection part through a liquid outlet tube, and the waste liquid cylinder 6 is connected to the peristaltic pump 5 through a tube.

[0041] The dialysis tube 1 includes a dialysis outer tube 11, a dialysis inner tube 12, and a dialysis membrane. The outer dialysis tube 11 is sleeved on the periphery of the inner dialysis tube 12. There is a gap between the outer dialysis tube 11 and the inner dialysis tube 12 to facilitate blood circulation. The outer dialysis tube 11 is hollowed out to facilitate blood entering the outer dial...

Embodiment 2

[0049] This embodiment provides a polytetrafluoroethylene-polyurethane-nano-silver composite material and a preparation method thereof. The polytetrafluoroethylene-polyurethane-nano-silver composite material has good biocompatibility and antibacterial properties, and is used for hemodialysis The built-in dialysis tube has good application prospects. The polytetrafluoroethylene-polyurethane-nano silver composite material is prepared through the following steps:

[0050] Step 1: Weigh 54g of concentrated polytetrafluoroethylene dispersion, 38g of diisocyanate, 14g of polycaprolactone diol, stir and mix and heat to 80°C, add 0.08g of 1,4-butanediol and stannous octoate to it 0.06g, continue to stir and maintain the heating temperature to react for 3h, then increase the temperature to 90℃, and add 0.13g trimethylolpropane monoallyl ether and continue to react for 3h to obtain the polytetrafluoroethylene-polyurethane composite material;

[0051] Step 2: Disperse the polytetrafluoroethy...

Abstract

The invention discloses hemodialysis equipment and relates to the field of medical equipment. The hemodialysis equipment comprises a dialysate container, a dialysis catheter, a peristaltic pump, and awaste liquid cylinder which are connected in sequence; the dialysis catheter comprises an outer dialysis catheter body, an inner dialysis catheter body and dialysis film, the outer dialysis catheterbody sleeves the inner dialysis catheter body, a gap is reserved between the outer dialysis catheter body and the inner dialysis catheter body, and the dialysis film wraps the inner dialysis catheterbody; the inner dialysis catheter body is of a U-shaped or V-shaped structure, and a liquid inlet and a liquid outlet are formed in an opening; the dialysate container is connected with the liquid inlet through a liquid inlet catheter, and the peristaltic pump is connected to the liquid outlet through a liquid outlet catheter; nanometer silver is fixed in catheter stocks of the inner dialysis catheter body and the outer dialysis catheter body. The dialysis catheter is placed in the artery of the human body, the process is not needed that blood is pumped out of the body and then is subjected tohemodialysis, accordingly, the blood pressure of the human body is not influenced, and the hemodialysis catheter is economical and safe and has little wound; the dialysis catheter can be retained inthe blood vessel and used for multiple times, and hemodialysis is conducted continuously.

Description

Technical field [0001] The invention relates to the field of medical equipment, in particular to a hemodialysis equipment. Background technique [0002] Hemodialysis is based on the principle that solute flows from the side with high concentration to the side with low concentration. The two solutions of blood and dialysate are simultaneously introduced into the dialyzer with hollow fiber semi-permeable membrane, so that the blood is located in the hollow fiber semi-permeable membrane. The dialysate is located on the other side of the hollow fiber semi-permeable membrane, so that the solution on both sides of the membrane can remove medium and small molecular toxins in the human blood through diffusion and osmosis. At the same time, the electrolytes in the blood can also pass through The osmotic effect is balanced, so as to achieve the purpose of blood purification. [0003] Hemodialysis is also a common method to treat edema diseases, acute and chronic renal failure (uremia), and ...
