The system of sterilization of medical devices that pack is basic function experiment
The system that pack points to the sterilization here only " system of asepsis protective screen " or SBS, the author thinks, there are 3 to must want contented requirement in system of protective screen of asepsis of functional sex respect, it is the integrality that pack respectively (PackagingIntegrity) , the protection that pack (Packaging Protection) and convenient / clean open sex (Easy/CleaningPeel) .
The 6.1 integrality that pack
Pack to sterilization of medical devices for, form a sealed system to assure to be opposite of all kinds and harmful cutting off microbially is a foundation, also be must. This kind cuts off the gender is in by paper aluminium model makes the field of composite material flexible package that give priority to very general perhaps, but pack to needing the medical devices of sterilization for, the sterilization method that anticipates when union will consider, often can face contradictory choice, because be in home‘s existing and popular sterilization method, annulus oxygen ethane (EtO) aeriform sterilization because its cost is the most welcome with the general adaptability to material, but method of this kind of sterilization posed a challenge to packing integrality however: It asks to pack must breathe freely, because EtO also should cross this sealed system that pack,enter inside go exterminating interior of the system that pack microbial.
From this knowable, to satisfy EtO kind the need that wants the sterilization way that breathe freely, the material that we choose to form sterilization of medical devices to pack inner packing system now must be satisfied breathe freely but the function that wants block mushroom again at the same time, must choose to take enough small hole so and the stuff that has certain and mechanical strength, already so called porous material, of course their hole summary is less than harmful such ability prevent microbial diameter effectively be entered microbially. Class packs the medical treatment that at present this kind of commonly used porous material has those who include to come from Dupont company not to have the Tyvek of the material that spin cloth, Ovantex that comes from Oliver-Tolas company and clean to sanitation sex and bore diameter size to have firm demand to wait with paper, this kind medical wrapping paper has much home company to be able to be offerred. And notable is these porous material oneself do not have very good direct processability to be able to form a complete inner packing to cut off system, the exterior process instrumentation such as gelatinize of such as of their need course is gotten thereby and other material is become to pack by treatment together cut off systematic function.
On the other hand, porous breathe freely the one part that material just makes inner packing system, another part inspects the form that pack to differ can be the high polymer film of of all kinds and different structure, box suction model, they add up to means to be machined through the heat of all sorts of commonly used types cut off in order to come true into a whole inner packing system microbial the function that enters the interior that pack.
And examine system of this inner packing is whole, according to existing standard standard, it is to consult commonly ASTMF1929-1998, already " lubricious solution of toluene amine Lan Ran filters way of check proved recipe " , the recipe of fluid of toluene amine Lan Rong has in ASTMF1929 give out, but specific experimental operation method did not give out in this standard, and what must point out is, this experiment operation method still has craftsmenship very much, need course grooms simply ability is OK, but integral difficulty of the experiment is not great.
The means of high-energy ray sterilization of and so on of contented to be Gamma, E-Beam and the system of inner packing asepsis of the design, because its do not have permeability requirement, also need not reuse is porous the material that pack, but the integrality requirement that packs a system internally is same still, the leak hunting method that can use those who press wrong way and so on to apply to sealing to pack a system at this moment will check, domestic and internationally also a lot of blame show qualitative standard will consult, opposite for easy place wants on the operation. Advantageous of course is, general material of this kind of sealing all is high polymer plastic material, the way that the probability that the melt heat between them adds up to occurrence leakage wants to compare agglutinate of glue relying on besmear wants many low.
The 6.2 protection that pack
Protection demand bearing asks to integrality for it is very easy be understood, packing the most primitive function is for protection the product keeps abreast of and evolution is mixed into stimulative sale convenient use wait for add sex function, it is inner packing system or outer packing system without giving thought to so, its protection requirement is same substantially, just go up in form figuration type somewhat difference.
To the protection requirement of inner packing system, ask oneself of the material that pack wants to have particular mechanical strength already, the combinative department of the different material that asks to make system of this inner packing again also should have particular strength, and normally this kind of union is to pass all sorts of heat to add up to a method to come true, the heat that often is used adds up to means to include common heat to close, high frequency heat closes and ultrasonic heat closes etc.
The mechanical intensity of material oneself is very easy be decided, should detect only generally speaking the tensile strength of material, expose tear strength of intensity, breach, be able to bear or endure the index of groovy and mechanical function such as broken intensity can get probably data, and current and commonly used material, for instance of all kinds and compound film, Tyvek is mixed medical wrapping paper, these their mechanical function index also are very easy inquire from all sorts of ways.
The heat that complex case is material union department combines the control of intensity size, because want to consider material oneself machine,component of function, gelatinize and property, heat adds up to means and heat to combine the element such as equipment, want to give out directly so a general and applicable heat combines intensity range have a challenge very much, the product that this must combine to be packed and reference before historical experience data ability is OK.
Heat adds up to intensity to cross big or too small metropolis to bring an issue. Heat adds up to intensity to cross old saying to be able to have two problems, it is cannot clean open, because exceeding heat adds up to intensity to be able to cause material very easily to seal area to tear off in heat, the inner bonding strength that seals intensity to be more than material oneself when heat especially and material is microcosmic form compare again flimsy when, for instance medical wrapping paper kind material; 2 be cannot convenient open is used, pack convenient open to medical devices kind the potential client of the product, the doctor with the very great pressure in be in an operation namely or body are very frail for the patient that takes care of without the person again, dispute often can attract one of crucial points that they purchase, and too big heat adds up to intensity to be able to let open a product to pack become very difficulty perhaps cannot open it with right kind. Heat adds up to intensity to cross little word to be able to cause protection to be not worth apparently, the product can drop to be in thereby from inside inner packing system actual and current adequate protection cannot get in carrying
6.3 convenient / clean open sex
Convenient / requirement of clean open sex is more subjective the demand that at the same time again certain difficulty is achieved, because can consult in the index that when judging, did not quantify,saying it is subjective is, and the standard that opens inner packing system arrives now also cannot be qualitative even give out, so can different person is opened same approve a product pack and reach different outcome.
Convenient / the heat between the material itself that clean open sex asks to pack a system to composition and different material closes place have very high demand, so the mechanical intensity of material oneself wants qualification, material heat seals place heat to add up to intensity to want moderate, cannot too tall.
