The online dosing peritoneal dialysis machine of liquid pocket typeTechnical field
This utility model relates to a kind of medical apparatus and instruments, especially relates to the online dosing peritoneal dialysis machine of liquid pocket type that is used to give treatment to acute or chronic renal failure, multiple organ failure, MOF, poisoning medicine or toxic poisoning.
Background technology
Liquid pocket type peritoneal dialysis machine is abdomen to be passed through powder be mixed with peritoneal dialysis liquid through the bipolar reverse osmosis pure water of medical grade; Be placed in the special-purpose liquid bag,, peritoneal dialysis solution imported patient's abdominal cavity like peritoneal dialysis catheter again through a kind of pipeline of inserting in the patient abdominal cavity; The inner membrance dialysis solution carries out mass exchange through the intravital omentum majus of patient in the abdominal cavity; Redundant moisture in the removal, in micromolecule kidney property toxin and the body is corrected soda acid and electrolyte disturbance, to reach the therapy equipment of blood purification.
At present; Common both at home and abroad be non-online liquid pocket type dosing peritoneal dialysis machine; Mostly the peritoneal dialysis solution that configures is that concentration of glucose is respectively 1.5%, 2.5%, 4.5% lactate peritoneal dialysis liquid, or bicarbonate salts, and common peritoneal dialysis liquid bag is three kinds of specifications such as 0.2L, 5L, 10L dress; Routine abdomen is in the daytime passed through 4 bags of 0.2L peritoneal dialysis liquids of treatment use, and abdomen passed through to treat and can select to use 5L～10L peritoneal dialysis liquid night.Existing liquid pocket type peritoneal dialysis machine exists the shortcoming of equipment price costliness, the supporting special use of consumptive material needs; Promote the use of inconvenience; The lactates peritoneal dialysis liquid causes remarkable infringement to internal organs such as patient's liver, the heart, brain and substance in vivo metabolism easily in addition; And the preservation of bicarbonate salts peritoneal dialysis liquid requires height, long easy breed bacteria of resting period, and perhaps volatilization reduces concentration.And need to shut down replacing peritoneal dialysis liquid bag in the treatment, and the underdosage of treatment usefulness, therapeutic effect is poor, is easy to cause patient to carry out abdomen for a long time and passes through, and makes the abdominal cavity omentum majus not repair chance, causes peritoneal membrane function comparatively fast to lose.
