Description
Technical Field
The utility model relates to the technical field of medical supplies, especially, relate to a waste liquid bag for CRRT.
Background
Crrt (continuous renal replacement therapy), a blood purification treatment technique that continuously and slowly removes water and solutes by a long-time, continuous extracorporeal blood purification method of 24 hours or nearly 24 hours per day, to replace impaired renal function. Compared with the common hemodialysis, the CRRT prolongs the time of blood purification treatment and reduces the treatment efficiency per unit time, so that the influence of the change of the solute solubility and the volume in the blood on the organism is minimized.
CRRT treatment is taken as an important support means for rescuing critical patients at present, and the success rate of the critical patients is greatly improved, so that the CRRT is more and more widely applied to various medical institutions, but the CRRT treatment faces a troublesome problem of waste liquid treatment. At present, almost all blood purification pipelines provided by manufacturers only have 1-2 waste liquid bags, the liquid inlet pipe and the liquid outlet pipe of each waste liquid bag are arranged on the same side, the capacity of each waste liquid bag is different from that of 10000ml in 5000-.
Different dialysis centers and ICUs exist, and the specific methods for treating waste liquid have different degrees of difference, and mainly comprise two methods: firstly, a machine is set to a liquid bag replacing mode, a waste liquid bag is separated from a pipeline, the waste liquid bag is conveyed to a disposal room, the waste liquid bag is overturned and hung on a hook, a liquid outlet of the waste liquid bag is opened, after the waste liquid is drained, the waste liquid bag is connected with the pipeline, and the treatment is continued; in the second method, the machine is switched to a liquid bag replacement mode, the waste liquid bag is separated, a new waste liquid bag is connected again, and the treatment is continued.
Both of the above methods have certain drawbacks and limitations. The first method is a method commonly used by most dialysis centers and ICUs at present, the method does not increase the treatment cost of patients additionally, but does not meet the requirements of blood purification standard operation regulations and hospital feelings, and has larger hospital feelings risk, the method is adopted to treat the waste liquid for about 4min each time, only a blood pump rotates under a liquid bag replacement mode, the blood evolution is not carried out, the waste liquid treatment time is 24-96min when CRRT treatment is carried out for 24h, the treatment time of blood purification is shortened, and the blood purification efficiency is reduced. The second method meets the requirements of blood purification standard operating regulations and hospital infection, but still needs frequent separation of waste liquid bags and pipelines, so that certain hospital infection risks exist, and the treatment cost is high. The cost of one waste bag is about 35 yuan, the cost of the waste bag required by the CRRT treatment of the patient for 24h is about 210 yuan 840 yuan, and the cost is not beneficial to the treatment of the patient.
From this it can be seen that there are three major problems facing the current treatment of CRRT waste streams: risk of nosocomial infections, cost of treatment, and efficiency of treatment.
