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 condition of decline of renal function in humans, which can cause the inability of patients to excrete endotoxin, maintain the stability of electrolytes such as sodium, potassium, calcium, etc. and the acid-base balance of the human system. Early chronic renal failure can be treated by drugs, but when the condition deteriorates to the uremic state, it is necessary for the patient to adopt a treatment method of hemodialysis or peritoneal dialysis for a lifetime other than the renal transplantation treatment.
Hemodialysis is a process of introducing the patient's blood and dialysate into an extracorporeal dialysis apparatus simultaneously, removing excessive toxins and excessive moisture accumulated in the blood by using a semipermeable membrane of the dialysis apparatus, supplementing bases to correct acidosis, and adjusting electrolyte disorders to replace the excretory function of the kidneys. In the dialysis treatment process, hemodialysis can rapidly remove solutes and water of small molecules, but the hemodialysis can rapidly lose the functions of the residual kidneys and has great influence on blood circulation in vivo, so that the blood-vessel-free dialysis liquid is not suitable for people suffering from heart failure, poor vascular conditions, mental disorders and the like. Thus, when the patient's peritoneal membrane is well functioning and unsuitable for hemodialysis, the method of peritoneal dialysis is considered.
Peritoneal dialysis is to use the peritoneal membrane as a semipermeable membrane, infuse dialysate into the peritoneal cavity through an abdominal tube, remove toxins through dispersion, correct electrolyte and acid-base balance disorder, and achieve ultrafiltration dehydration through the osmosis principle (glucose is added into the dialysate to increase the osmotic pressure of the dialysate) so as to replace the excretion function of the kidney. Compared with hemodialysis, the peritoneal dialysis is performed at home, and the peritoneal dialysis can be performed by oneself or by family members, so that the peritoneal dialysis solution is infused into the peritoneal cavity only through the peritoneal dialysis tube, the dialysis equipment is relatively simple, the residual kidney function of a patient is well protected, and the influence and the requirement on the heart function are small. Patients undergoing peritoneal dialysis are required to face long-term, high frequency treatment afflictions. In contrast to treatment hemodialysis performed 3-4 times per week, peritoneal dialysis is performed daily, and in some cases 3-4 times per day, severely affecting the patient's normal life.
Therefore, how to reduce the frequency of peritoneal dialysis and prolong the period of peritoneal dialysis, and the normal life of patients is not affected while the treatment effect of the patients is ensured, which is a key problem to be solved by the current peritoneal dialysis treatment method.
Disclosure of Invention
The invention aims at the defects of the existing peritoneal dialysis technology, innovates the peritoneal dialysis method and device, introduces a superfine fiber soft material tow into the peritoneal cavity on the basis of the traditional gravity peritoneal dialysis, and continuously adsorbs substances such as urea in the dialysate by the superfine fiber surface containing materials (such as zinc oxide particles) capable of adsorbing toxic substances such as urea and the like, thereby reducing the concentration of urea in the dialysate, further keeping the dialysate at a larger osmotic pressure for a longer time, prolonging the service time of the dialysate and reducing the dialysis frequency.
The technical scheme of the invention is as follows: a device for absorbing urea toxins by superfine fiber soft substance tows comprises a peritoneal dialysis liquid conveying and changing system, an abdominal tube, an abdominal interface, an iodophor cap and superfine fiber soft substance tows, wherein the peritoneal dialysis liquid conveying and changing system comprises a dialysis liquid bag, a liquid conveying tube, a sealing plug, a waste liquid bag, a waste liquid tube and a three-way ball valve.

The end part of the infusion tube is provided with a superfine fiber soft substance filament bundle storage structure, the cross section of the structure is three-quarter circle, and the superfine fiber soft substance filament bundle can be clamped in the structure. The superfine fiber soft material filament bundle consists of superfine fiber, support filament, small silica gel balls and one large silica gel ball with diameter slightly larger than that of the abdominal cavity joint. When the superfine fiber soft material tows flow along with the peritoneal dialysis fluid, the large silica gel balls are clamped at the peritoneal dialysis interface, and the small silica gel balls flow into the peritoneal cavity along with the peritoneal dialysis fluid. The iodophor cap is connected with the abdominal cavity interface, can completely cover the large silica gel ball, and ensures 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 small silica gel ball-to-ball constrained fiber continuously adsorbs the metabolic wastes in the peritoneal dialysis solution, so that the urine poison in the peritoneal dialysis solution is always kept at a low concentration, the use time of the dialysis solution is greatly prolonged, the replacement frequency of the dialysis solution 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 absorbing urea toxins by using the superfine fiber soft material tows are material blends of polymers with biological safety, zinc oxide and other absorbable metabolic wastes, 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 absorbent particles are reliably combined and do not fall off. The length of the filament bundle is about 1.5-3 times of that of the peritoneal dialysis tube, so that when the large silica gel ball is clamped at the abdominal cavity interface, the filament bundle in the abdominal cavity has enough length, thereby increasing the area of the fiber scanning in the abdominal cavity and increasing the efficiency of the fiber bundle for absorbing metabolic wastes. The middle section of the fiber bundle is restrained by a plurality of small silica gel balls, so that the fiber bundle can not be intertwined when the fiber bundle is soaked or flows through the dialyzate, and the fiber bundle can be ensured to smoothly enter the abdominal cavity and can be unfolded in the abdominal cavity. Holes are formed in the surface of the large silica gel ball, so that the large silica gel ball is clamped by forceps, and the whole silk bundle is conveniently taken out of the abdominal cavity. The middle of the superfine fiber tows contains supporting filaments with the diameter of 100-300 microns, the supporting filaments are made of the same material as the superfine fibers, and the supporting filaments can be filaments or yarns, so that when the superfine fiber soft substance tows are taken out from the abdominal cavity, the supporting filaments can bear larger breaking force, and the tows are ensured not to break in the abdominal cavity. The support wire may also be made of other materials with high strength that are biosafety, the diameter being determined by the tension that needs to be borne.
The invention relates to a use method of a device for absorbing urea toxins by superfine fiber soft material tows, wherein one end of an abdominal permeation tube is placed into an abdominal cavity through minimally invasive surgery, one end outside an abdominal permeation tube body is connected with an abdominal cavity joint, a sealing plug is broken off to enable dialysate to flow out of a dialysate bag, a three-way ball valve is rotated to enable the abdominal permeation tube to be communicated with a perfusion tube, when stable dialysate flow exists in the perfusion tube, a storage structure on the perfusion tube is extruded, small silica gel balls are sequentially extruded into the perfusion tube from the tail end of the perfusion tube, each small silica gel ball is extruded, after tows among the small silica gel balls are completely unfolded, the next small silica gel ball is extruded, when the dialysate injection amount in the abdominal cavity is enough, a large silica gel ball is extruded, flows along with the dialysate and is clamped at an abdominal cavity joint, the three-way ball valve is rotated to close the perfusion tube, a peritoneal dialysis transfusion system is pulled out, and the large silica gel ball is covered by an iodophor cover and is tightly connected with the abdominal cavity joint. When the dialysis fluid is stored in the body for a set time, the iodophor cap is taken down, the holes of the large silica gel balls are clamped by forceps, the superfine fiber soft material tows are taken out, then a new peritoneal dialysis fluid delivery and exchange system is connected to the peritoneal interface, the three-way ball valve is rotated to enable the peritoneal dialysis fluid delivery tube to be connected with the waste liquid tube, the waste liquid bag is placed on the ground, the waste liquid is introduced into the waste liquid bag through the action of gravitational potential energy, the three-way interface is rotated after the waste liquid is drained, the infusion tube is connected with the peritoneal dialysis fluid and the superfine fiber soft material tows are injected into the peritoneal cavity again.
