Benefits of technology

[0005]The present invention provides a small, light weight preferably disposable refrigerator unit of a type which may be kept on hand at the shipping location without concern for loss of cooling capacity during storage of the refrigerator unit. That is, the refrigerator units may be kept on-hand without need for refrigerating the refrigerator units.

Problems solved by technology

Currently limited options exist for the transportation of temperature sensitive products and materials.
In general, these options are largely limited to use of insulating packaging and cooling of the package contents with ice and the like.
The inclusion of frozen material makes the bags heavy and cumbersome.

Embodiment Construction

[0013]With reference to the accompanying drawings in which like elements are designated by like numerals, FIG. 1 shows a presently preferred embodiment of the invention where refrigeration unit 10 is provided for cooling the contents of a clinical specimen carrier or transport bag 12. The carrier bag 12 may be a conventional envelope-type transport bag comprised of two side walls of thermally insulating material joined along three sides and sealable along a fourth side. In FIG. 1 the bag 12 is only partially shown for convenience of illustration.

[0014]The refrigerator unit 10 has a tubular exterior housing 14 in which is provided a compressor 16 configured for circulating a thermodynamic working fluid such as freon through a cooling coil 18. Appropriate provision, not shown in the drawings, is made for venting heat from the working fluid to the outside environment exterior to the unit 10. A fan or blower 20 drives air cooled by coil 18, as suggested by the arrows, towards a cold air...

Abstract

A specimen carrier bag of the type useful for transporting clinical specimens from a specimen collection site to a laboratory site for analysis is provided with a small, light weight preferably disposable refrigerator unit which can be stored for extended periods without loss of cooling capacity and activated for cooling specimens in the carrier bag during transport, thereby avoiding the need to keep dry ice on hand for this purpose. In presently preferred embodiments the refrigerator unit has a battery driven compressor for circulating a working fluid such as freon or a battery powered thermoelectric heat pump.

Description

[0001]This application claims priority to provisional patent application 60 / 974,076 filed Sep. 20, 2007FIELD OF THE INVENTION[0002]The invention relates to refrigerated carrier bags for transportation of temperature sensitive materials, such as but not limited to the shipping of clinical laboratory specimens.STATE OF THE PRIOR ART[0003]Currently limited options exist for the transportation of temperature sensitive products and materials. In general, these options are largely limited to use of insulating packaging and cooling of the package contents with ice and the like.[0004]For example, clinical laboratory specimens are shipped from a specimen collection location, e.g. a physician's office, to a specimen analysis location, e.g. a clinical laboratory. Currently clinical specimens which require refrigeration during transport are placed in a larger insulated container which protects the clinical specimens against ambient heat, or may be packaged in a transport bag or container togeth...
