The present disclosure generally relates to apparatus to maintain at least temporarily maintain biological samples (e.g., eggs, sperm, embryos) at cryogenic temperatures, and to facilitate identification of stored biological samples.
Long-term preservation of cells and tissues through cryopreservation has broad impacts in multiple fields including tissue engineering, fertility and reproductive medicine, regenerative medicine, stem cells, blood banking, animal strain preservation, clinical sample storage, transplantation medicine, and in vitro drug testing. This can include the process of vitrification in which a biological sample (e.g., an oocyte, an embryo, a biopsy) contained in or on a storage device (e.g., a cryopreservation straw, cryopreservation tube, stick or spatula) is rapidly cooled by placing the biological sample and the storage device in a substance, such as liquid nitrogen. This results in a glass-like solidification or glassy state of the biological sample (e.g., a glass structure at the molecular level), which maintains the absence of intracellular and extracellular ice (e.g., reducing cell damage and/or death) and, upon thawing, improves post-thaw cell viability. To ensure viability, the vitrified biological samples must then be continuously stored in a liquid nitrogen dewar or other container containing the liquid nitrogen, which is at a temperature of negative 196 degrees Celsius.
There are, however, a number of concerns in how these biological samples are being stored, identified, managed, inventoried, retrieved, etc.
For example, each harvested embryo is loaded on a rigid embryo straw, stick or spatula. On the case of tube, the tube may be closed (e.g., plugged) at one end and open at the other end. The cryopreservation storage devices containing or holding the embryos are cooled as quickly as possible by plunging the cryopreservation storage device with the biological material into liquid nitrogen at a temperature of approximately negative 196 degrees Celsius, for example to achieve vitrification. More particularly, multiple cryopreservation storage devices are placed in a goblet for placement in the liquid nitrogen storage tank. The goblet attaches to the liquid nitrogen storage tank such that the multiple cryopreservation storage devices are suspended in the liquid nitrogen. Labels that are manually written-on using a suitable marker pen or printed using a custom printer are attached to the straw and/or the goblet. Such labels can include identification information corresponding to the individual that the embryo was harvested from and other suitable information (e.g., a cryopreservation storage device number, a practitioner number, etc.).
The size of the cryopreservation storage devices and the storage conditions in liquid nitrogen generally require special labels, and even then can adversely affect the persistence of markings on the respective cryopreservation storage devices. For instance, it is not uncommon for labels bearing identification information corresponding to the individual that the embryo was harvested from to separate from the corresponding cryopreservation storage device. Even if the goblet includes the identification information, it should also be noted that cryopreservation storage devices are often separated from the corresponding goblet, thereby resulting in one or more cryopreservation storage devices floating within the liquid nitrogen storage tank.
With regard to storage and management of these biological samples, facilities employ personnel that are required to maintain the liquid nitrogen storage tanks (e.g., by refilling them with liquid nitrogen when needed) and manage the inventory of stored biological samples (e.g., by performing periodic accountings). There is, however, little recordkeeping with regard to the proper storage of these biological samples. For example, subsequent identification or otherwise handling of the vitrified biological sample can involve removal of the sample from temperature-controlled storage and exposure of the sample to ambient temperature, thus potentially risking the viability of the sample.
Accordingly, it is desirable to provide new apparatus for preserving and identifying biological samples (e.g., vitrified biological samples) at suitably cold temperatures.
A container includes a vial, cap, and wireless transponders to store and identify samples of biological material at cryogenic temperatures (e.g., vitrified biological samples), for instance held by cryopreservation storage devices (e.g., straws, tubes, sticks, spatulas). A carrier includes a box, thermal shunt, thermal insulation to store and identify arrays of containers that hold cryopreservation storage devices with samples of biological material at cryogenic temperatures. Various apparatus include wireless transponders positioned and oriented to enhance range, and allow interrogation while retained in a carrier. Various apparatus can maintain the biological material at or close to cryogenic temperatures for prolonged period of times after being removed from a cryogenic cooler, and can allow wireless inventorying while maintaining the biological samples at suitably cold temperatures.

The headings and Abstract of the Disclosure provided herein are for convenience only and do not interpret the scope or meaning of the embodiments.
The container 100 includes a vial 104, a cap 106, a number of wireless transponders 108a, 108b (two shown), and optionally a number of sensors 110 (one shown).
The vial 104 has a first end 112a, a second end 112b, and a side wall 114. The second end 112b is opposed from the first end 112a across a length L of the vial 104, and the side wall 114 extends between the first and the second ends 112a, 112b to delimit an interior cavity 116 of the vial 104 from an exterior 118 thereof. The vial 104 has an opening 120 at the first end 112a thereof, and the second end 112b may be closed or sealable. The vial 104 takes the form of a tube, which may have a circular profile or cross section, or alternatively may have other shapes (e.g., rectangular, hexagonal, octagonal). The opening 120 of the vial 104 may, for example, be circular, although the opening 120 may have other shapes. The second end 112b of the vial 104 may, for example, have a flat surface 122, the flat surface 122 perpendicular to the length L or longitudinal axis of the vial 104. The vial 104 may be formed of any materials suitable to being deposited into a cryogenic bath, for example various polycarbonate, aromatic polyimidies (e.g., PMMA, Kapton, Upilex), and is preferably transparent.
The cap 106 is sized and shaped to removably close the opening 120 at the first end 112a of the vial 104. As best illustrated in
Returning to
The wireless transponders 108 are able to withstand cold temperatures (e.g., negative 150° C.; negative 196° C.) and continue to operate. In particular, the wireless transponders 108 are preferable able to withstand multiple instances of temperature cycling between cold temperatures (e.g., negative 150° C.; negative 196° C.) and relatively warmer temperatures to which the containers may be exposed when removed from a cryogenic cooler or dewar. The wireless transponders 108 may advantageously take the form of passive wireless transponders, which rely on power from interrogation signals to provide responses, for example via backscattering. MEMS transponders may be particularly suitable for operation at cold temperatures.
Each of a first and a second wireless transponder 108a, 108b encodes a unique identifier. The wireless transponders 108 respond to wireless interrogation signals with response signals encoding the unique identifiers, for example via backscattering. In some implementations, both the first and the second wireless transponders 108a, 108b may encode a same unique identifier as one another, which uniquely identifies the container 100. Alternatively, a nontransitory processor-readable medium may store a relationship between pairs of unique identifiers corresponding to pairs of wireless transponders 108 carried or born by a same respective container 100.
In particular, a first wireless transponder 108a has a respective antenna 138a (e.g., first antenna) which is coupled to a respective transponder circuit 139 (e.g., radio, transmitter, backscatter circuit, illustrated in
The first wireless transponder 108a is fixed to a portion of the vial 104, for example via an epoxy. The epoxy may encapsulate the first wireless transponder 108a, or the combination of the vial 104 and epoxy may encapsulate the first wireless transponder 108a, to securely attach and provide environmental protection thereto. Alternatively, the first wireless transponder 108a may be molded or encapsulated in a portion of the vial 104 itself. The second wireless transponder 108b is fixed to a portion of the vial 104, for example via an epoxy. The epoxy may encapsulate the second wireless transponder 108b, or the combination of the vial 104 and epoxy may encapsulate the second wireless transponder 108b, to securely attach and provide environmental protection thereto. Alternatively, the second wireless transponder 108b may be molded or encapsulated in a portion of the vial 104 itself.
As noted, the container 100 may also include or bear one or more sensors 110 (only one shown). The sensor(s) 110 may take a variety of forms, such as, for example, wireless sensors which not only sense conditions but also include an antenna and transponder circuit (e.g., radio, transmitter, backscatter circuit) to wirelessly transmit measurements or other indications of sensed condition from the sensors 110. The sensor(s) 110 are able to withstand cold temperatures (e.g., negative 150° C.; negative 196° C.) and continue to operate. In particular, the sensor(s) 110 are preferable able to withstand multiple instances of temperature cycling between cold temperatures (e.g., negative 150° C.; negative 196° C.) and relatively warmer temperatures to which the containers 100 may be exposed when removed from a cryogenic cooler or dewar.
The one or more sensors 110 may include one or more temperature sensors, and preferably passive temperature sensors, operable to sense temperature in the vial 104, at the vial 104 and/or external to the vial 104. Temperature sensors may include any one or more of optical based temperature sensors (e.g., laser temperature sensors, infrared temperature sensors); or thermocouples, thermistors and/or resistance temperature detectors, or MEMS based temperature sensors in which a frequency of mechanical vibration or oscillation of a vibratory element varies with temperature.
The sensor(s) 110 may be fixed to a portion of the vial 104, for example via an epoxy. The epoxy may encapsulate the sensor(s) 110, or the combination of the vial 104 and epoxy may encapsulate the sensor(s) 110, to securely attach and provide environmental protection thereto. Alternatively, the sensor(s) 110 may be molded or encapsulated in a portion of the vial 104 itself.
In at least some implementations, the sensor(s) 110 may be integral to the wireless transponders 108a, 108b, employing the antenna 138a, 138b and transponder circuits 109 of the wireless transponder 108a, 108b for transmitting information outward from the container 100. Alternatively, one or more sensor(s) 110 may be separate and distinct from the wireless transponders 108a, 108b.
The container 100 may also optionally include or bear one or more machine-readable symbols 144a, 144b. The machine-readable symbols 144a, 144b may take a variety of forms, for example one-dimensional machine readable symbols commonly referred to as barcode symbols, or two-dimensional machine-readable symbols for instance Matrix code symbols. The machine-readable symbols 144a, 144b can be composed of machine-readable symbol characters selected from any of a large variety of symbologies, and readable via any type of machine-readable symbol reader. The machine readable symbols (e.g., ink, media) 144a, 144b are able to withstand cold temperatures (e.g., negative 150° C.; negative 196° C.) and continue to operate. In particular, the machine readable symbols 144a, 144b are preferable able to withstand multiple instances of temperature cycling between cold temperatures (e.g., negative 150° C.; negative 196° C.) and relatively warmer temperatures to which the containers may be exposed when removed from a cryogenic cooler or dewar and remain optically readable.
Each of the one machine-readable symbols 144a, 144b encodes a unique identifier. In some implementations, both a first and a second one machine-readable symbol 144a, 144b may encode a same unique identifier as one another, which uniquely identifies the container 100. Alternatively, a nontransitory processor-readable medium may store a relationship between pairs of unique identifiers corresponding to pairs of one machine-readable symbol 144a, 144b carried or born by a same respective container 100.
The machine-readable symbols 144a, 144b may be fixed to a portion of the vial 104, for example via an epoxy. The epoxy may encapsulate the machine-readable symbols 144a, 144b, or the combination of the vial 104 and epoxy may encapsulate the machine-readable symbols 144a, 144b, to securely attach and provide environmental protection thereto. Alternatively, the machine-readable symbols 144a, 144b may be molded or encapsulated in a portion of the vial 104 itself. The epoxy and/or vial should be sufficiently transparent at a set of wavelengths (e.g., visible wavelengths, infrared wavelengths, ultraviolet wavelengths) that the machine-readable symbols 144a, 144b can be optically scanned or read.
While not illustrated, the container 100 may also optionally include or bear one or more human-readable symbols, for example alphanumeric characters or words or serial numbers.
In at least some implementations, the machine-readable symbols 144a, 144b may be integral to the wireless transponders 108a, 108b, e.g., printed, embossed, inscribed or otherwise applied thereto.
The container 100 may optionally include a fixed thermal mass 146 and a thermal insulator 148 that at least partially surrounds the thermal mass 146 to prevent or inhibit thermal conduction. The thermal mass 146 may be located in the interior cavity 116 of the vial 104. The thermal mass 146 has a larger thermal mass than a thermal mass associated with the sample cryopreservation storage device(s) 102 and the biological materials 103 held by the sample cryopreservation storage device(s) 102. The thermal mass 146 may take the form of a piece of non-ferrous metal or a metal impregnated polymer where the metal is in the form of small pieces, particles or strands that are sufficiently small and discontinuous as to prevent or retard the formation of currents therethrough. The thermal insulator 148 may take a variety of forms, including but not limited to an aerogel (e.g., a microporous solid in which the dispersed phase is a gas, a gel in which the liquid component is replaced with a gas, for instance silica-based, alumina-based, chromia-based, tin oxide-based and carbon based aerogels).
The thermal mass 146 is located along the length L of the vial 104, preferably spaced from both the first wireless transponder 108a and the second wireless transponder 108b by at least a minimum defined distance (e.g., 3 mm) to prevent interference with wireless communications via the wireless transponders 108a, 108b.

The array of receivers 218 may be an integral portion of the carrier box 202, for example molded as part of a molding the carrier box 202. Alternatively, the array of receivers 218 may be a separate and distinct structure, for instance press or friction fit into the carrier box, or even snap fit into the carrier box via tabs and slots or other engagement or securing mechanism.

A space is formed between the exterior wall 416 of the exterior shell 410 and the interior wall 420 of the interior insert 412a, and between the exterior bottom 414 of the exterior shell 410 and the interior bottom 418 of the interior insert 412a. The space may be filled with a ridged or semi-ridged insulation, for example an aerogel. Less preferably, the space may evacuated or entrap a vacuum. Less preferably, the space may be filled with a fluid, for instance an inert gas, or even less preferably air.
The specimen holder 1102 has a distal end to carry a specimen 1103, such as biological materials and/or samples (e.g., eggs, sperm, and zygotes), and a proximate end which is attached to, or integral with, the cap 1106. In implementations, the specimen holder 1102 and the cap 1106 may be a single, unitary structure, and the specimen holder 1102 may include a spatula 1143 having a flat surface 1145 at the distal end of the specimen holder 1102, with the specimen 1103 being frozen to the flat surface 1145.
The cap 1106 may have a top portion 1125 and a side wall 1126 extending from the top portion 1125, the side wall 1126 delimiting a portion of the cap 1106 which is smaller in extent relative to the top portion 1125 in a direction transverse to the longitudinal axis of the vial 1104 so that the side wall 1126 can be inserted into the interior of the vial 1104, the top portion 1125 acting as a stopper to limit the depth of insertion of the side wall 1126 into the vial 1104. The cap 1106 may have threads 1132a, for example on an outer surface of the side wall 1126 to mate with corresponding threads 1132b on an inner surface of the side wall 1114 of the vial 1104.
Implementations may advantageously include a number of ports 1205 and/or vents 1210 (see
Although the term “vent” has been used herein to describe through-holes (which are not necessarily round), which allow gas (e.g., air) to escape the vial 1104 and the term “port” has been used to describe through-holes which allow liquid nitrogen into the vial 1104, these terms are interchangeable in some cases. For example, the structure of the through-holes used for the vents 1210 and ports 1205 may be simple apertures and therefore may function primarily as vents 1210 or ports 1205 depending on their position relative to the top and bottom of the container 1100 and depending on operational conditions (e.g., depending on whether a container 1100 is being lowered into or raised out of a cryogenic bath). In some implementations, the ports 1205 and vents 1210 may include valves, flaps, screens, filters, or other structures, to restrict the flow of gas or liquid to a specific direction vis-à-vis the interior of the vial 1104 and this may result in structures which act as dedicated ports 1205 or vents 1210. In some cases, the outer jacket 1107 (discussed below) may include through-holes in correspondence with the through-holes in the vial 1104 to facilitate ingress and egress of liquid and/or air.
The cap 1106 may be formed of any of a variety of materials, for example polymers, for instance thermoplastics, such as polypropylene or polyethylene, and/or any other suitable material that withstand temperatures common in cryogenic applications without significant degradation. An outer surface of the top portion 1125 of the cap 1106 may include a plurality of facets 1136 to facilitate gripping when tightening or loosening the cap 1106. While the cap 1106 is generally illustrated as having a portion thereof securely received within the opening of the vial 1104, in some implementations, the cap 1106 may alternatively be sized to receive a portion of the vial 1104 within an opening in the cap 1106, as in the example of
The container includes an outer jacket 1107 covering at least a portion of an exterior surface of the vial (see
The inner surface of the jacket 1107 may be attached to the exterior surface of the vial, e.g., friction fitted, heat fitted, and/or via adhesive, in implementations in which the outer jacket 1107 is to remain associated with the particular vial throughout the lifecycle of the container 1100. In some implementations, the inner surface of the jacket 1107 may be removably attached to the exterior surface of the vial 1104 to allow removal and replacement of the outer jacket 1107, e.g., if the outer jacket 1107 is to be associated with more than one vial 1104 (or vice versa). In such a case, there may be an elastic compression fit and/or a friction fit between the vial 1104 and the outer jacket 1107. In implementations, the inner surface of the jacket 1107 and/or the exterior surface of the vial 1104 may include deformable protrusions (not shown) which compress elastically to form a compression fit between the vial 1104 and the outer jacket 1107. In implementations, the inner surface of the jacket 1107 and/or the exterior surface of the vial 1104 may include opposing threads or ridges to secure the vial 1104 within the outer jacket 1107 (or, in other words, to secure the outer jacket to the vial). In implementations, outer jackets 1107 may be manufactured separately from vials 1100 and, for example, retrofitted onto existing vials 1104.
The outer jacket 1107 may have openings 1151 (see
In implementations, an arrangement of arms 1152 may extend from the bottom opening of the jacket 1107 in a longitudinal direction of the outer jacket 1107 to support a platform 1150, e.g., a solid, disk-shaped platform, which is oriented in a plane which is transverse to the longitudinal axis of the outer jacket 1107 (see
The container 1100 may include one or more wireless transponders 1108a, 1108b, 1108c (collectively 1108). As discussed above in the context of
In implementations, at least a portion of the platform 1150 itself may, for example, take the form of a radio frequency identification (RFID) button cell (see, e.g.,
In implementations, the circuitry of the first antenna 1138a, and possibly the transponder circuit 1139a, may be at least partially covered by a non-conductive label 1144a (see
In implementations, the circuitry of the second antenna 1138b and transponder circuit 1139b may be at least partially covered by a label 1144 (e.g., a label formed of a non-conductive material) with machine-readable symbols and/or human-readable information formed thereon (e.g., of the sort discussed above with respect to
Epoxy may encapsulate the second wireless transponder 1108b, or the combination of the jacket 1107 and the epoxy may encapsulate the second wireless transponder 1108b, to securely attach and provide environmental protection thereto. Alternatively, the second wireless transponder 1108b may be at least partially molded or encapsulated in a portion of the outer jacket 1107 itself.
In implementations, machine-readable symbol(s) may be fixed to other portions of the vial 1104, cap 1106, and/or outer jacket 1107, e.g., via epoxy. In at least some implementations, the machine-readable symbols may be integral to the wireless transponders 1108, e.g., printed, embossed, inscribed or otherwise applied thereto.
As discussed above, the first antenna 1138a may be fixed on an outer surface of the platform 1150 at the bottom end of the jacket 1107, in which case the beam axis of the first antenna 1138a of the first wireless transponder 1108a extends in a direction orthogonal to a plane of the platform 1105, which is in a direction along the longitudinal axis of the outer jacket 1107. As noted above, by providing the first and second wireless transponders 1108a, 1108b as separate and distinct substrates, the shape and features of the outer jacket 1107 may advantageously be employed to ensure that the beam axes are orthogonal to one another. Such an arrangement and positioning may facilitate interrogating or reading from below the vials, for example when held in storage in a cryogenic-cooled container.
In implementations, the circuitry of the third antenna 1138c and the transponder circuit 1139c may be at least partially covered by a non-conductive label with a machine-readable symbol(s) formed thereon so as to be visible on the top of the container 1100. In implementations, a label (not shown) with a machine-readable symbol formed thereon may be applied to the outer surface (e.g., the top surface 1124) of the cap 1106 without a wireless transponder being present. The label may be at least partially covered at a later time by attachable wireless transponder circuitry, such as, for example, circuitry formed on a carrier having an adhesive backing or a carrier which is attachable using adhesive, e.g., epoxy. The epoxy may encapsulate the third wireless transponder 1108c, or the combination of the cap 1106 and the epoxy may encapsulate the third wireless transponder 1108c, to securely attach and provide environmental protection thereto. Alternatively, the third wireless transponder 1108c may be molded or encapsulated in a portion of the cap 1106 itself.
Physically attaching a wireless transponder to a portion of a cap may be particularly advantageous where the elongated specimen holder (e.g. spatula, stick, or straw) is fixed to the cap, either as a single unitary piece structure or via adhesive or a weld (e.g., high frequency or radio frequency welding, ultrasonic welding). In such implementations, a wireless transponder encoding unique identifying information (e.g., a unique identifier) may be undetachably or permanently physically coupled to the elongated specimen holder via the cap, and hence undetachably or permanently physically associated with a specimen, even where the elongated specimen holder and/or specimen are withdrawn from a vial.
The container 1100 may include or bear one or more sensors 1110 (see
The various structures described herein may have dimensions conforming with a standardized format (e.g., American National Standards Institute (ANSI) format, Society for Biomolecular Screening (SBS) format, Society for Laboratory Automation and Screening format (SLAS), etc.). For example, in some embodiments, arrays of receptacles or other described structures can have a footprint that matches an SBS-format rack to facilitate use in an automated storage facility.
The various structures described herein may be comprised of any of a large variety of materials, although materials that would interfere with radio or microwave frequency communications will typically be avoided, or such materials spaced sufficient far (e.g., 3 mm) from antennas of wireless transponders and/or the anticipate location of interrogators or readers used to communicate with such wireless transponders. Further, the various structures described herein not only establish positioning or spacing in a two-dimensional plane (e.g., horizontal or XY plane), but also establish positioning or spacing in a third dimension (e.g., vertical or Z axis). At least some of the structures described herein support the containers 100 to ensure that a given location of the container (e.g., bottom surface with button coin RFID transponder) is spaced within a given distance or range (e.g., 20 mm; 15 mm) of an exterior of a carrier 200, 300, 400 and/or a location (i.e., interrogation station or reader station, e.g., located proximate a cryogenic cooler) at which an antenna of an interrogator or reader will be when the carrier 200, 300, 400 is placed at a reading location.
The various structures described herein as employing an aerogel may in some implementations consist of an aerogel. In other implementations, such structures may comprise an aerogel along with one or more other components. For example, some structures may employ a plastic (e.g., polypropylene) that is doped with an aerogel, which may advantageously enhance a dimensional stability of the structure. For instance, an array or cassette may include an aluminum bucket with an array of apertures sized and shaped to hold a plurality of containers, a top spacer of a plastic doped with aerogel with an array of apertures sized and shaped to hold a plurality of containers, and an outer sleeve of a plastic doped with aerogel that at least partially surrounds the aluminum bucket and top spacer.
The various implementations and embodiments described above can be combined to provide further implementations and embodiments. All of the commonly assigned US patent application publications, US patent applications, foreign patents, and foreign patent applications referred to in this specification and/or listed in the Application Data Sheet, including but not limited U.S. patent application 62/900,281, filed Sep. 13, 2019; U.S. patent application 62/880,786, filed Jul. 31, 2019; U.S. patent application 62/879,160, filed Jul. 26, 2019; U.S. patent application 62/741,986, filed Oct. 5, 2018; U.S. patent application 62/741,998, filed Oct. 5, 2018; and U.S. patent application Ser. No. 16/593,062, filed Oct. 4, 2019, are each incorporated herein by reference, in their entirety. These and other changes can be made to the embodiments in light of the above-detailed description.
Various changes can be made to the embodiments in light of the above-detailed description. For example, thermal insulators may consist of an aerogel or may comprise an aerogel and another non-aerogel thermal insulator (e.g., plastic). In some implementations, a thermal insulator may comprise an aerogel housed by a protective shell (e.g., plastic shell) or housing. One or more thermally insulative structures may additionally or alternatively be employed, for example one or more thermal breaks (e.g., walls defining cavities that a vacuum or near-vacuum, or holding an inert gas, or even a non-inert gas).
In general, in the following claims, the terms used should not be construed to limit the claims to the specific implementations and embodiments disclosed in the specification and the claims, but should be construed to include all possible implementations and embodiments along with the full scope of equivalents to which such claims are entitled. Accordingly, the claims are not limited by the disclosure.
