Fluid therapy is an important means of modern clinical treatment, as an important means of complement humoral and provide a variety of nutrients in the body of preferential measures, infusion of insoluble particles can cause disease of heart head blood-vessel, pulmonary embolism risk factors, the generation of insoluble particles and production enterprise level of processing technology, production control, clinical infusion operation, drug combination, cork, Filter material facies potest pertinet.

Studium in filter liquidam medicina

The provisions of the state apparatus infusionis must install filters can be used for clinical purposes of liquids, liquid medicine filter use is one of the effective methods to prevent particles from entering the human body, the national standard of GH8368 particle antibacterial rate of liquid filter requirements, and industry standard YY086.1, the design of liquid filter, particle pollution, filtration efficiency, infusion velocity are required.

Studium in filter membrana

Dum designing filter, debemus reddere satis operam ad lectio membrana materia, qualis, dynamic Indicatores infusionem processus. De studio liquidi filter combined cum orci practica applicationem, simulatio infusionem modum, ex diversis campester et latere tubo extergimus intelligere variis filter membranam.

Ad effectum filter membrana apertura

Filter membrane aperture is an important prerequisite to ensure particle removal rate, the selection of pharmaceutical filter membrane should be dominated by 0.8um-1.2um aperture filter material, after several tests, can ensure a higher filtration efficiency, but also can reach the filter speed requirements of the filter membrane include: Fiber composite membrane, polyester heavy ion film, nylon film, flow attenuation test research shows that the membrane pore size, the greater the material is loose, the smaller the filtration velocity attenuation, and vice versa, it shows that various membrane on particulate matter – tiny particles in the liquid has a different degree of entrapment and adsorption, the deceleration slowed, caused by blocked part of the membrane pore size polyester after infusion in weight increase, the heavy ion membrane Filtration celeritate paulatim tardus et Polypropylene non - texta filtrum est a altum filter film, magna pore mole, disorganized, particula interception maxime pendeat in crassitudine film.

Membrane filter material into infusion rate of particle filter test shows that the influence of different material of membrane aperture is the same, although said all have differences, but give the effect of particle rate in the process of transfusion, membrane contact with solution for a long time, the material of the fiber, impurities may be due to the membrane solution, the surface density of membrane layer of loose and fall off into the liquid, through intravenous input Et producendum potential periculis, fibra effundendum numerum potest esse ex diversis filter materiales et illic es manifeste differentias, quamvis numerus filtration est idem, sed gravibus non facile ad fibra, filter materia, quae est ad effudit in filter.

Influence of Adsorption Effectus: omnes Filter membranes habent diversas gradus adsorption effectus in intravenous medicamentis, praesertim super humilis - dose medicinae, et filter membranes habere specialis heterotropic adsorption in medicinae. From the point of the average adsorption rate, low heavy ion membrane, polyether sulfone membrane on drug adsorption, the adsorption effect of infusion of drugs and drug related species, and the line length is related to drug adsorption is determined by the membrane material, the surface of the membrane structure and the structure of the filter, adsorption of drugs also have bigger difference, membrane materials with static in order to improve the particle entrapment more, And easy to overlook the electrostatic adsorption of drugs, so should choose as far as possible thin, small adsorption of inert materials for membrane, or the use of special processing method to eliminate electrostatic effect, infusion tube has a larger surface area, adsorption of drugs have some improvement production process or increase the pipe inner surface layer, make the drug adsorption quantity to a minimum.
