There is provided compositions and methods for the storage of red blood cells. The compositions are additive solutions comprising adenine, dextrose, mannitol, NaH2PO4, and optionally NaCl and / or N4HCl. Composition are preferably used with oxygen-depletion refrigerated storage of red blood cells and may optionally be employed with nutrient supplements extending the useful shelf life of stored blood.

The present invention includes a method for reducing viral, bacterial, protozoan, fungal and other parasitic contamination from a biological solution. Biological solutions include, but are not limited to, solutions comprising blood, a blood component, cell culture or a component of a cell culture. In accordance with the present invention, there is provided, a method of inactivating a pathogen in blood or blood product in a container, comprising contacting at least one of said blood, blood product and container with a composition of the present invention. In accordance with the present invention, there is provided, a medical device comprising at least a surface treated with an anti-pathogenic composition of the present invention or containing at least an anti-pathogenic composition of present invention. In accordance with the present invention, there is provided, an anti-pathogenic composition for use in disinfecting fluids and biological tissues and surfaces contaminated with fluids and / or biological tissues, which comprises an anti-pathogenic amount of at least one quaternary ammonium compound in association with an acceptable carrier. A preferred anti-pathogenic composition of the present invention further comprises a bisguanidine compound. In accordance with the present invention, there is provided a method for inhibiting in vitro or ex vivo infection or replication of human immunodeficiency virus in a biological fluid, comprising treating said biological fluid with an effective inhibiting amount of a bis-guanidine compound or a derivative thereof, and at least one quaternary ammonium compound in combination with a pharmaceutically carrier, such as DMSO.

The invention discloses a portable outdoor blood storage device, and belongs to the technical field of medical equipment. A refrigerating device is used for storing blood transfusion bags; liquid nitrogen is used as refrigerants; after the liquid nitrogen is vaporized, heat is absorbed to lower the temperature in a blood bin; the air pressure in a liquid nitrogen bin can be increased through the vaporized liquid nitrogen; the vaporized liquid nitrogen is recompressed by a compressor as liquid for flowing back into the liquid nitrogen bin; the operation is circulated to achieve the purpose of refrigerating the internal of the blood bin; an unfreezing device uses warm water for unfreezing; the unfreezing temperature is not higher than 37 DEG C; frozen blood bags are put in an unfreezing bin;the warm water flows out from a water outlet to pass through the frozen blood bags; through a heat transfer mode, the blood bags are unfrozen; low-temperature water enters an infrared heating devicefrom a water inlet, and is circulated through a water pump; and through the design, the low-temperature water can be heated as far as possible, so that the unfreezing speed is accelerated.

The invention discloses a method for monitoring blood storage period which comprises steps of: providing a temperature variation blood timer connected with blood storage device; according to the variation of holding temperature and time, after statistics match to calculate the content of ATP in red blood cell; then evaluating the rest storage time of blood and displaying the rest storage time via the temperature variation blood timer. The inventive method has the advantages of being able to keep the temperature variation blood timer with blood, of being able to collect the temperature and cumulated storage time real-time.

The invention discloses a bar code scanning device for cold storage in blood preservation. The technical solution to the problem in prior art is that the barcode-attached blood cartridges placed in the cold storage cabinet can be automatically and quickly scanned one by one, therefore, reducing manpower cost and improving work efficiency. The scanning device of the invention further comprises a rectangle frame with a beam on the front side. A rail is mounted at the front end of the beam in the longitudinal direction of the beam; the rail is provided with a slide block; a longitudinal bar is arranged on the upper end of the rectangular frame; a scanning head is arranged on the rear lower end surface of the longitudinal bar; the scanning eye of the scanning head is arranged facing downwards; the lower end of the beam is provided with a transmission mechanism which is capable of driving the longitudinal bar to move in lateral translation; the longitudinal bar is connected with the transmission mechanism through a connecting block and a transverse T-shaped fixing plate; the transverse T-shaped fixing plate is a provided with a control board in connection with the scanning head. Compared to the prior art, the device of the invention can automatically enter the bar code information automatically, reduce labor cost and improve work efficiency.
