Problems solved by technology

[0003] In the existing dialysis device, the blood is inside the membrane during hemodialysis, and the filtrate is outside the membrane, that is to say, the patient’s blood needs to be pumped out of the body for filtration. However, this method has the following disadvantages, especially for long-term hemodialysis For the patients, it is inconve

Example Embodiment

[0046] Example 1

[0047] A reverse pure ultrafiltration dialysis device in vivo, such as Figure 1-3 As shown, it includes an ultrafiltration dialysis unit 1, a negative pressure generating unit 2 and a waste fluid drainage unit 3. The negative pressure generating unit 2 is connected to the ultrafiltration dialysis unit 1, and the waste fluid drainage unit 3 is connected to the The ultrafiltration dialysis unit 1 is interconnected.

[0048] By adopting the above technical solution, the ultrafiltration dialysis unit 1 is set to be inserted into the central vein of the patient, and the negative pressure generating unit 2 is provided to extract the air inside the ultrafiltration dialysis unit 1 to make the ultrafiltration dialysis unit 1 generate Negative pressure, using the pressure difference between the inside of the ultrafiltration dialysis unit 1 and the central vein of the patient, so that the toxin water in the patient’s blood is filtered back to the inside of the ultrafiltrat...

Example Embodiment

[0070] Example 2

[0071] The difference from Example 1 is that the outer surface of the box body 29 is also provided with a protective layer, and the protective layer is prepared by the following method:

[0072] Take the following raw materials and weigh in parts by weight: 18-25 parts of epoxy resin, 8-12 parts of calcium carbonate powder, 10-12 parts of nano silver powder, 12-16 parts of phenolic resin, 8-10 parts of titanium dioxide powder, 12 alcohol esters 2-4 parts, 2-4 parts triethanolamine, 1-3 parts higher alcohol fatty acid ester complex, and 30-40 parts water;

[0073] S1. Add the weighed alcohol ester twelve, triethanolamine, higher alcohol fatty acid ester complex and water into a mixer and stir for 20-30 minutes at a stirring speed of 600-800r / min to prepare a mixed solution;

[0074] S2. Add epoxy resin, calcium carbonate powder, nano silver powder, phenolic resin, and titanium dioxide powder into the pulverizer for pulverization until the particle diameter of the mat...

Abstract

The invention relates to the technical field of medical instruments, in particular to an in-vivo reverse isolated ultrafiltration dialysis device. The device comprises an ultrafiltration dialysis unit, a negative pressure generation unit and a waste liquid drainage unit, the negative pressure generation unit communicates with the ultrafiltration dialysis unit, the waste liquid drainage unit communicates with the ultrafiltration dialysis unit, and the ultrafiltration dialysis unit comprises a base, a sealing plate and an ultrafiltration dialysis beam. The device can be buried in the central vein of a patient for a long time, and can bring convenience to the patient especially for the patient needing hemodialysis for a long time. The device brings possibility that the dialysis patient can still walk during dialysis, more importantly, the treatment cost of the dialysis patient can be effectively reduced, the puncture frequency of the dialysis patient can be effectively reduced, pain is relieved, and it can be guaranteed that the patient can conduct dialysis smoothly. Meanwhile, the device has no requirement on the specification of liquid collecting bags, and the liquid collecting bagswith different specifications can be used, so that the practicability of the device is better.

Description

technical field [0001] The invention relates to the technical field of medical instruments, more specifically, it relates to a reverse simple ultrafiltration dialysis device in the body. Background technique [0002] Hemodialysis, referred to as hemodialysis, also known as artificial kidney or kidney dialysis in popular terms, is a kind of blood purification technology. It uses the principle of semi-permeable membrane to remove various harmful and redundant metabolic wastes and excess electrolytes from the body through dispersion, so as to purify the blood and correct the water-electrolyte and acid-base balance. The thickness of the semi-permeable membrane used in hemodialysis is 10-20 microns, and the average pore size on the membrane is 3 nanometers, so only small molecules with a molecular weight of less than 15,000 and some medium-molecular substances are allowed to pass through, while macromolecules with a molecular weight of more than 35,000 are allowed to pass through...
