Description
Technical field
The invention belongs to the technical field of medical appliance, medical supplies, relate to the technology of medical packaging, container, more particularly, the present invention relates to a kind of doubly-linked PVC medicinal liquid storage bag.In addition, the invention still further relates to the adherence preventing material of described doubly-linked PVC medicinal liquid storage bag, and the operating procedure of described adherence preventing material.
Background technology
At present, peritoneal dialysis mainly contains two kinds: continuous ambulatory peritoneal dialysis (CAPD) and automatization's peritoneal dialysis (APD).Two kinds of peritoneal dialysis are all persistence, namely all the time all too much in purged body water and refuse, the similar normal kidney of this point.Like this, the dietary restrictions of patient is just harsh unlike hemodialysis.
Continuous ambulatory peritoneal dialysis (CAPD): be peritoneal dialysis mode the most frequently used at present, can carry out in any clean place.Required device comprises: peritoneal dialysis solution storage bag and waste liquid storage bag, the connection short tube be connected with doubly-linked bag and the peritoneal dialysis catheter implanted of doubly-linked.
CAPD utilizes gravity, by connecting short tube and peritoneal dialysis catheter, peritoneal dialysis solution is injected abdominal cavity.Peritoneal dialysis solution is deposited a period of time (being generally 4 ~ 6 hours) at intraperitoneal, just can get rid of the old peritoneal dialysis solution containing toxin and unnecessary moisture, be recycled in waste liquid storage bag.Then change the packed peritoneal dialysis solution of doubly-linked and inject intraperitoneal, start new one and take turns peritoneal dialysis.Peritoneal dialysis solution once pour into and discharge is called and changes liquid.Change liquid at every turn and about need 30 minutes.Except changing the liquid time, patient equally can continue normal daily life and work with Healthy People.Many patients the exchange of peritoneal dialysis solution is arranged in rise morning with evening sleep before.The number of times that every day exchanges depends on the state of an illness needs of patients undergoing peritoneal dialysis, is generally every day 3 ~ 4 times.
Because peritoneal dialysis is simple to operate, patient can oneself carry out at home, and expense is lower than hemodialysis, therefore in China Hong Kong, the dialysis patient of more than 80% selects peritoneal dialysis treatment.There are tens00000000 populations in China, and the sickness rate of End-stage renal disease is about 100 people/1,000,000, and absolute number of the infected reaches 120,000 people every year, and most people is dead because can not get due treatment without long-term economic ability to bear.Therefore, CAPD therapy widelys popularize very large economic benefit and social benefit at home.
In CAPD treatment, although the transfusion bag of some dialysis solution doubles as waste liquid storage bag, then constantly carry the empty bag of the original peritoneal dialysis medicinal liquid storage bag as effluent discharge storage bag like this, thus make patient feel trouble, and easily infect.
In order to patient is easy to operate and reduce and infect, substantially all adopts the waste liquid storage bag of medicinal liquid storage bag that peritoneal dialysis solution is housed and sky at present, be connected short tube, the doubly-linked bagging apparatus of peritoneal dialysis catheter connection.Such patient is after dialysis terminates, and doubly-linked bag can separate with being connected short tube, so do not need to carry doubly-linked bag.
But, for this doubly-linked bagging apparatus, to be equipped with peritoneal dialysis medicinal liquid storage bag and waste liquid storage bag laminating packaging together, when carrying out sterilization treatment, oxirane (EOG) sterilizing and gamma-radiation sterilizing methods can not be adopted, and need to adopt high-temperature high-pressure steam sterilizing (121 DEG C, 1.0MPa, 40min)., the heating effect of high temperature and high pressure steam can make between peritoneal dialysis medicinal liquid storage bag and waste liquid storage bag outer surface, all produce adhesion between the inner surface of waste liquid storage bag.After producing this adhesion, when carrying out peritoneal dialysis treatment operation, there will be trouble: one is be difficult between peritoneal dialysis medicinal liquid storage bag and waste liquid storage bag peel off; Another is after dialysis terminates, and when effluent discharge, discharge liquor can not normally can be discharged because waste liquid storage bag can not open.
In order to prevent the adhesion between peritoneal dialysis medicinal liquid storage bag and waste liquid storage bag, in prior art, there is following technical scheme:
Adopt between two bags, place a slice PE (polyethylene) or the isolation of PP (polypropylene) thin film, although so temporarily solve the adhesion between doubly-linked bag, the adhesion between waste liquid storage bag inner surface can not be solved.Someone attempts the nonactive liquid of non-active gas to waste liquid storage bag filling 2.5% ~ 30% capacity or 0.8 ~ 7.8% capacity, but this can affect regularity, the convenience of product palletize, cause sterilizing difficulty, but also deposit the shortcoming of operating difficulties in use, the capacity of waste liquid such as cannot discharged after accurate-metering dialysis, is difficult to the dialysis-effect of evaluate patient.
Someone attempts on the inner surface of waste liquid storage bag, arrange the some concavo-convex bars extended along bag main body longitudinal direction in recent years.If arrange concavo-convex bar on the whole inner surface of bag main body, the transparency of bag main body will be destroyed, namely the observability of situation in bag is affected, thus be difficult to the exception confirming the dialysis discharge liquor (waste liquid) reclaimed, the former material cost manufacturing waste liquid storage bag is caused to raise in addition, and the surrounding sealing the margin of bag forms vulnerable area, this part easily produces the defects such as pore.
