Portable unit and pipeline thereof for peritoneal dialysis treatment
Technical field
The invention belongs to the medical instruments technical field, be specifically related to portable unit and the pipeline thereof of peritoneal dialysis treatment.
Background technology
During the degree that can't work fully to kidney when renal failure, client need sustains life with dialysis, and two kinds of main dialysis process are hemodialysis and peritoneal dialysis.Expense and the curative effect of two kinds of dialysis are basic identical, but peritoneal dialysis at cost effectiveness, protect residual renal function, facilitate the patient and save the aspects such as medical resource more excellent.
Peritoneal dialysis (Peritoneal dialysis, PD) be to utilize patient's oneself peritoneum as semipermeable membrane, utilize the dialysis solution that action of gravity will prepare through conduit, to pour into patient's peritoneal cavity, like this, in the peritoneum both sides, exist the Concentraton gradient of solute poor, the solute of high concentration one side is to low concentration one side shifting (dispersion); Moisture is from the high side shifting (osmosis) of oozing of a hypotonic side direction.By abdominal dialysis liquid, constantly change, to reach the purpose of removing interior metabolism product, toxicant and correcting water, electrolyte balance disorder.
Peritoneal dialysis periodically is injected into peritoneal dialysis liquid in peritoneal cavity, between solution and blood flow, strides across that peritoneum spreads and permeation-exchange, and the normocrinic waste products of kidney, for example carbamide and kreatinin are removed in these exchanges.Peritoneal dialysis liquid is by the pipeline in a kind of patient of inserting abdominal cavity, as the abdominal cavity of peritoneal dialysis catheter by its input patient, the inner membrance dialysis solution carries out mass exchange by the peritoneum in the patient body in abdominal cavity, unnecessary moisture in removal, in micromolecule kidney toxin and body, correct soda acid and electrolyte disturbance, to reach the purpose of blood purification.
Current peritoneal dialysis device is a kind of automatic equipment, for the patients undergoing peritoneal dialysis of growing up, for the kidney disease treatment in latter stage.Although and existing automatization peritoneal dialysis machine is easy to use, exist the shortcoming of the expensive 100,000/platform of equipment price, the supporting special use of consumptive material pipeline 100 yuan/cover needs, it is very inconvenient to promote the use of; In clinical peritoneal dialysis treatment, often need medical worker or patient oneself manually in peritoneum, to pour into peritoneal dialysis liquid simultaneously, inconvenience very, cause dialysis property abdominal cavity infection, impact dialysis quality, and severe one need to stop dialysis, to treatment, makes troubles.Therefore, the peritoneal dialysis device of expectation should be firm, lightweight and portable, cost is low and be easy to use.
The present invention can automatically complete aerofluxus, drain, injection, time-out and pause etc., can carry out multiple peritoneal dialysis mode: as intermittent peritoneal dialysis (IPD), intermittent peritoneal dialysis at night (NIPD), CCPD (CCPD) and damp formula peritoneal dialysis (TPD).Patient and assistant all can arrange daily routines with being under no restraint or participate in work in power by day, and the patient is reintegrated into society, and are society, family's creation of value.
