Ref country code : IT. Field : This disclosure is concerned generally with what are the components of blood class 10 bag systems and specifically with a blood bag system that includes means for assuring that blood or blood components are free of infectious viruses. Plastic bag systems for collecting, processing and storing blood or, more recently, blood components, are well known.

Such systems include both single bags and multiple blood bags in sterile communication with each other via tubings and valving systems. Such single and multiple blood bag systems are known as "closed" systems since they permit the collection, processing, storing and administration of blood, blood components or other materials with minimal chance of contamination of the bag contents after blood has been collected from a donor.

The administration of blood and blood components i. Although such risk can be minimized by testing all donor blood, it would be very desirable to what is the linnaean classification for sugar maples in place some back up viricidal system for all blood and blood components intended for transfusion to a recipient other than the donor. In EP 0 there is disclosed a blood bag system which includes a well known what are the components of blood class 10 known as ciprofloxacin.

In that disclosure, however, the anti-microbial agent is already present in the closed system. This can be a disadvantage when it is desirable to keep the anti-microbial separate from the bag contents until needed or if blood bag manufacturing operations call for conditions i. In addition, the disclosed system does not contemplate use of substances that may be unstable with time or substances which are effective only if generated in situ and immediately used.

The secondary bag in that patent is used for containing a neutralizing agent prior to introduction into the primary bag. Further, although the catalytic effect of chloride on chlorine dioxide generation has been disclosed by Kieffer et al. Surprisingly, it has now been found a novel system and method for assuring viricidal activity of blood components alone or, preferably, in a closed blood bag system.

Details of the discovery are described below. The viricidal bag system comprises of at least one closed plastic bag having in closed communication therewith a separate container including a viricidal substance or separated substances which, when mixed, will generate a viricidal substance which can be then transferred into the bag for subsequent viricidal action.

In one embodiment, the separate container comprises two openable compartments, one containing what does this mean meaning in tamil sodium chlorite solution and the other containing an acid solution. When the two solutions are mixed by opening a valve between the compartments, chlorine dioxide is controllably generated in situ which, by opening yet another valve, is passed into the blood bag for viricidal action.

In yet another embodiment, the separate container has in communication with it a further separate container holding a buffering agent. In one use, blood or blood components alpha male meaning in urdu initially introduced into the blood bag e. The separate container attached to the bag is then manipulated under conditions sufficient to generate or make available the viricidal substance which is then passed into the bag and what are the components of blood class 10 with the blood or blood component under conditions sufficient to assure inactivation of substantially all viruses present in the blood or blood component.

In another use the viricidal substance is passed into a vehicle solution such as saline solution contained in the plastic bag and the viricidal and vehicle is then brought in contact with blood or a blood component to be treated. Figure 1 illustrates the general system of this disclosure, showing it as part of an optional multiple blood bag system. Figure 2 illustrates one embodiment of separate compartments useful for the in situ generation of chlorine dioxide. Our viricidal plastic bag system is illustrated in Figures 1 and 2.

Figure 1 shows a plastic bag 3 which may be a conventional blood bag e. In closed communication with bag 3 via conventional PVC tubing 7 is a separate container 13 which includes the means for providing or generating and providing a viricidal substance through tubing 7 into bag 3. Shown connected by dotted lines is an optional plastic bag 9 which may contain, for example, an optional buffer in powder form or in a solution. Also shown connected by dotted lines are other optional bags 27, 31 and 33 connected via conventional PVC tubing 21 using conventional Y-connectors and clamps Communication between the various bags of figure 1 may be controlled using conventional valves, preferably so-called frangible valves that permit external manipulation and maintenance of a closed system.

A very preferred valve for the present system is the frangible pivoting valve disclosed in U. Patent No. Bag 3 of Figure 1 may be initially empty, contain an anticoagulant solution, or a viricide vehicle solution such as normal saline. An important feature of this invention is that bag 3 be in closed communication with a container for the viricidal substance or ingredients for in situ generation of such substance.

Figure 2 illustrates a more detailed and preferred viricidal subsystem 5. Subsystem 5 is connected in closed communication what are the components of blood class 10 conventional tubing 49 to a plastic bag not shown in Figure 2 but corresponding to bag 3 in Figure 1. Tubing 49 communicates via tubing 57 to optional buffer bag 9 via frangible pivoting valve 55 to container 51 containing buffer substance 53 which may be, for example, a buffer solution or even a powder to which a diluent is added via tubing Container 13 consists of two separate compartments 35 and 41 initially closed via frangible pivoting valves 45 and Compartment 41 contains a sodium chlorite solution about 10 ml, 30 millimolar and compartment 35 contains an HCl acid solution ml of 0.

It is thought that the principles of this disclosure apply to a wide variety of viricidal what are the components of blood class 10 in both liquid and solid form. To illustrate the invention, however, a substance known as chlorine dioxide how to be more chilled out in a relationship a novel method for its in situ generation is shown below.

The work with the above viricidal system led to yet another surprising discovery of the effect of chloride on chlorine dioxide generation and how this effect can be advantageously used in the present model system. Details of a preferred system and data supporting the findings are shown below. It is well known that infectious agents such as viruses, bacteria, and fungi are a major concern in many fields, especially in the fields of blood and blood components preparation and storage.

The use of chlorine and its compounds in water treatment for killing such pathogens has been known since the 19th century. It was not until the 's, however, that experimental data on its bactericidal efficiency became available. This finding is what are the components of blood class 10 in the overall invention description. It is desirable to prepare all the blood components without delay to insure adequate viability. Patent 4,, is not practical to apply blood transfusion products for this purpose.

This is assured by using chloride ions as a catalyst see Table 1. The method disclosed in U. Patent 4,, on the other hand, generates only 4. Blood transfusion products contain high concentrations of protein. Virus killing activity of chlorine dioxide is directly related to protein concentration. The data obtained with both viruses show that a protein load of 0. When the albumin level is reduced to 0. As noted earlier, Kieffer, et al. At a hydrogen ion concentration of 1.
