Description
Technical Field
The invention relates to the field of clinical medical treatment, in particular to a dialysis device and a method used in peritoneal dialysis.
Background
Renal failure is a pathological state of renal failure of a human body, which can cause that the patient cannot excrete toxins in the body, and the electrolytes such as sodium, potassium, calcium and the like in the human body system are stable and balanced in acid and base. Early stage chronic renal failure can be treated by drugs, but when the condition deteriorates to a uremic state, a treatment method of hemodialysis or peritoneal dialysis is required for the life of the patient in addition to the kidney transplantation treatment.
Hemodialysis is to introduce the blood and dialysate of a patient into an extracorporeal dialysis device at the same time, remove excessive toxins and excessive water accumulated in the blood by using a semipermeable membrane of the dialysis device, supplement basic groups to correct acidosis, adjust electrolyte disorder, and replace the excretion function of the kidney. In the dialysis treatment process, small-molecule solutes and water can be rapidly removed by hemodialysis, but residual kidney functions can be rapidly lost by hemodialysis, and the hemodialysis has a large influence on in-vivo blood circulation, so that the hemodialysis is not suitable for people suffering from heart failure, poor blood vessel conditions, mental disorders and the like. Therefore, peritoneal dialysis is considered when the patient's peritoneal membrane is functioning well and not suitable for hemodialysis.
Peritoneal dialysis utilizes the peritoneum as the semipermeable membrane, injects the dialysate into the abdominal cavity through the peritoneal dialysis tube, removes toxins through the diffusion effect, corrects electrolyte and acid-base balance disorder, and achieves ultrafiltration dehydration through the osmosis principle (adding glucose into the dialysate to improve the osmotic pressure of the dialysate) to replace the excretion function of the kidney. Peritoneal dialysis compares in hemodialysis, and the dialysis process is carried out at home, can oneself or family members carry out peritoneal dialysis's manual operation, only need inject the dislysate into the peritoneal cavity through the peritoneal dialysis pipe, and dialysis equipment is simple relatively to it is better to patient's remaining renal function protection, and influence and the requirement to the cardiac function are less. Patients undergoing peritoneal dialysis, however, are confronted with long-term, high-frequency treatment. In contrast to 3-4 weekly treatments of hemodialysis, peritoneal dialysis is required daily, and in some cases 3-4 times a day, which seriously affects the normal life of the patient.
Therefore, how to reduce the frequency of peritoneal dialysis and prolong the period of peritoneal dialysis, which does not affect the normal life of the patient while ensuring the treatment effect of the patient, is a key problem to be solved by the current peritoneal dialysis treatment method.

The end part of the transfusion tube is provided with a superfine fiber soft substance tow storage structure, the section of the structure is three quarters of a circle, and the superfine fiber soft substance tow can be clamped in the structure. The superfine fiber soft substance tow consists of superfine fibers, a supporting wire, a plurality of small silica gel balls and a large silica gel ball, wherein the diameter of the large silica gel ball is slightly larger than that of the abdominal cavity joint. When the superfine fiber soft material tows flow along with the peritoneal dialysis solution, the large silica gel ball is clamped at the peritoneal dialysis interface, and the small silica gel ball flows into the abdominal cavity along with the peritoneal dialysis solution. The iodophor cap is connected with the abdominal cavity interface, and can completely cover the large silica gel ball to ensure sealing. The fiber is prepared from a polymer with biological safety, the surface of the fiber contains an adsorption material of metabolic wastes such as urea and the like, and the fiber constrained among the small silica gel balls continuously adsorbs the metabolic wastes in the dialysate in the abdominal cavity, so that the uremia in the dialysate in the abdominal cavity is always kept at a lower concentration, the service life of the dialysate is greatly prolonged, and therefore, the change frequency of the dialysate is reduced, the peritoneal dialysis frequency is reduced, and the peritoneal dialysis period is prolonged.
The raw materials of the fiber tows in the device for adsorbing uremia by the superfine fiber soft substance tows are blends of polymers with biosafety and materials capable of adsorbing metabolic wastes such as zinc oxide, and the blends are used for preparing superfine fibers by safe and reliable processing methods such as melt differential electrostatic spinning and the like, so that fiber matrixes and adsorbing material particles are reliably combined and do not fall off. The length of the tows is about 1.5-3 times of that of the peritoneal dialysis catheter, so that the tows in the peritoneal cavity have enough length when the large silica gel ball is clamped at the abdominal cavity interface, the area of the fiber in the peritoneal cavity is increased, and the efficiency of the fiber bundles for absorbing metabolic wastes is increased. The middle section of the fiber bundle is restrained by a plurality of small silica gel balls, so that the fiber bundle cannot be wound when flowing or soaking in dialysate, the smooth entering of the fiber bundle into the abdominal cavity is ensured, and the fiber bundle can be unfolded in the abdominal cavity. The surface of the large silica gel ball is provided with the holes, so that the large silica gel ball is conveniently clamped by tweezers, and the whole tow is conveniently taken out of the abdominal cavity. The middle of the superfine fiber tows contains supporting wires with the diameter of 100-300 microns, the supporting wires are made of the same material as the superfine fibers, and the supporting wires can be filaments or yarns, so that when the superfine fiber soft substance tows are taken out of the abdominal cavity, the superfine fiber soft substance tows can bear larger breaking force, and the tows cannot break in the abdominal cavity. The supporting wires can also be made of other materials with biosafety and higher strength, and the diameter is determined according to the tensile force required to be borne.
