Definitions

  • the specification relates to the design of a temperature-controlled system for the collection, storage and/or transportation of live cells, tissues, organs, vaccines, therapeutics, or other temperature sensitive materials.
  • the specification relates to a layered container system design for the collection and/or transportation of temperature sensitive materials.
  • Transportation challenges may include, among other things: exposure to extreme temperature ranges, delays in mail, postal, and courier delivery, difficulty enabling non-industrial depositors to properly cold-charge, and low success rates for non-invasive collection and depositing of samples.
  • Cells, tissues, and organs retrieved from non-invasive sources such as plucked hair follicles, cells derived from hair follicles, sperm, placental cells, umbilical cord cells and tissues, and urine derived cells, are affected by such transportation challenges.
  • These transportation challenges often result in sub-optimal cell viability and/or health, particularly when depositors are collecting, depositing, and shipping cell, tissue, and/or organ samples from a non-laboratory, non-industrial environment.
  • United States patent no. 10549900B2 describes a thermal storage system designed to enclose a retrievable payload using two layers of phase change material.
  • the first layer of phase change material has a phase change temperature within the target temperature range of the payload itself, and the second layer of phase change material has a range outside the target temperature, where the first layer prevents the second layer temperature from affecting the payload temperature.
  • the components of the thermal storage system are arranged in a vertical stack, such that the layers of phase change material do not completely surround the central payload on all sides evenly.
  • the temperature-controlled system of the present invention has many advantages over existing designs, including the design disclosed in US patent no. 10549900B2.
  • the arrangement of components is not a vertical stack, but instead a set of outwardly inscribed cylindrical containers custom-shaped to surround the central payload on all sides evenly. This is a more efficient arrangement because it limits the surface area through which cold-energy can dissipate outward and it ensures the payload has consistent temperature exposure protection from all directions.
  • the design of the present invention also has temperature-maintaining elements designed to be cold-charged using a standard non-laboratory fridge and freezer.
  • the temperature-controlled system of the present invention is designed to improve the rate of success for the depositing of temperature sensitive samples into the payload container, including the depositing of samples of living tissue sometimes collected non- invasively in non-laboratory settings.
  • the mouth of the payload container By widening the mouth of the payload container, reducing the height of the liquid so that it will only reach half way up the walls of the payload container, and integrating a ‘lock’ between the payload container base and the inner core base, the experience of a non-practiced non-expert in depositing sensitive materials successfully without spilling liquid from the payload container may be significantly reduced.
  • the payload container also incorporating a depression in the lid that limits the volume of air pockets within the payload container when it is sealed shut, these sets of features together create a substantially improved user-success design.
  • These types of features are completely missing from existing designs, including the design disclosed in US patent no. 10549900B2, which only allows for user-success in lab or industrial settings by trained personnel.
  • the inscribed cylindrical containers of the present disclosure that contain PCM and refrigerant surround the payload sample on all sides, which helps enable the entire temperature-controlled system to maintain a smaller footprint for the same cooling performance. This not only means the temperature-controlled system of the present invention may be less expensive to ship through the mail, it also may improve the probability that the cylinder containers will fit in refrigerators and freezers that may already be filled with other materials and therefore may improve user success.
  • the present disclosure describes designs for temperature-controlled systems that may be used for the collection, storage and/or transportation of living or temperature-sensitive material.
  • embodiments of the present invention relate to a temperature-controlled system comprising: (i) an insulation layer comprising a lid and a base; (ii) an outer core plastic cylinder housed in the insulation layer, wherein the outer core plastic cylinder comprises either a phase-change material (PCM) or a standard refrigerant; (iii) an inner core plastic cylinder housed within the outer core plastic cylinder, wherein the inner core plastic cylinder comprises either a PCM or a standard refrigerant; and (iv) a payload container that is housed within the inner core plastic cylinder.

  • the cells, tissues, or organs are plucked hair follicles, cells derived from hair follicles, sperm, placental cells, umbilical cord cells and tissues, and urine derived cells.
  • the payload container has a volume capacity to hold about 0.1 mL to about 100mL of liquid.
  • the payload container is used to transport living cells and is filled with an appropriate viability-maintaining transportation media.
  • the payload container is designed to have interlocking slots that align with slots on the inner core base to prevent the payload container base from twisting when the payload container lid is being twisted off.
  • the payload container lid is designed with a depression that takes some space in the cavity of the payload container base and which can be filled with a wide range of temperature monitors.
