Description
Technical field
The utility model is related to blood bag Bag Making Machine technical field, more particularly to a kind of blood bag Bag Making Machine and its half cutting apparatus.
Background technology
It is well known that blood bag Bag Making Machine by the PVC film materials of volume two by solve film, hemisection, membrane, spot welding, punching, upper tube, open
Bag, high-frequency welding cut the processes such as bag, torn edges, output blood bag finished product are made.
PVC (polyvinyl chloride) material is the current common condensate for being used for manufacturing intravenous infusion bag film.PVC material sheet
Body is nontoxic, it is likely that chemically reacted with drug, and PVC itself is a brittle substance, therefore when being processed into soft bag
In order to make PVC become it is transparent, soft need to add 40% or so plasticizer DEHP.These plasticizer can penetrate into drug and be inhaled by human body
It receives.The accumulation of the DEHP of a large amount may result in girl's precocity and boy's physiological development is unsound.And PVC can be produced in burning
The very strong dioxin-like chemical of toxigenicity causes prodigious harm to environment.Therefore, the soft bag infusion of PVC material is tried not
It is used in paediatrics, women breast-feeding their children, pregnant woman should be also restricted using PVC soft bags, and U.S. FDA is in September, 2001 to containing
The medicine of DEHP has only made safety evaluation, and has sent out notice with regard to this in July, 2002, and notice is clearly expressed to be contained to using
Have the worry of DEHP softening agent PVC safeties and taken limitation, replacement policy.
Although currently, non-PVC large infusion film have chemical inertness it is good, it is nontoxic, without adhesive and plasticizer, can be 121
DEG C high-temperature sterilization, the advantages that vapor permeability is low, softness is tough and tensile, the transparency is good, low temperature resistance is good, heat sealable, unlike
The soft bag of PVC material will produce hydrogen chloride and dioxin etc. when burning, and on environment without influence, is easily processed, meets environmental protection and want
It asks, is the developing direction of venous transfusion, but blood bag is essentially all to be made of medical PVC material.The performance requirement ratio of blood bag
General infusion bag is high, its direct and contacting blood does not require nothing more than the wholesomeness generally packed, intensity, flexibility and seal etc.,
But also to have good biological property, blood compatibility, haemolysis, pyrogen and haemocyte survival rate will reach prescribed requirement, also
It should be able to high pressure resistant steam sterilizing etc..
China's in September, 2000 stopped the examination ＆ approval to creating PVC packed in flexible pouchy infusion production lines, and it is big to be phased out PVC
Infusion bag；Infusion apparatus, blood bag, a variety of interposing catheters still use PVC to make；Due to being not found in energy in comprehensive performance and price
The substitute material to contend with PVC, PVC still rule disposable infusion set market.Domestic infusion market master big for a long time
The non-fields PVC are concentrated on, and are started late in the fields PVC, and are influenced not make a breakthrough by national policy.
