Description

  TECHNICAL FIELD The present invention relates to a dry sipper rack for transporting a cryobox or a cryobox transport / storage container used in a contracted storage service for frozen cells, etc. while being stored in a dry sipper that is a frozen sample transport container. .

  The cryopreservation method is widely used as a technique for preserving samples such as cells, tissues and pathological embedding cassettes used for test research, pharmaceutical production and food production for a long period of time. Samples such as cells and tissues are processed for freezing and then placed in a small container such as a vial. The containers are almost the same size manufactured and sold by various instrument manufacturers (for example, the outer dimensions are 134 mm long × 134 mm wide × 52 mm high, and can accommodate vials of various sizes inside. With a cryogenic liquefied gas, such as liquid nitrogen, which is housed in a plastic or paper cryobox that is easy to hold while holding the cryobox in a state of being cooled to a very low temperature. Each cryobox is stored in a cryopreservation container for cryopreserving in the gas phase or liquid phase, or a deep freezer that can be stored at extremely low temperatures, and kept in a frozen state.

  In recent years, when storing frozen samples, deposits in cell banks, backups in the event of accidents and disasters, backups when new analytical methods are found, reliability assurance during research and manufacturing, and collaborators There is a strong demand for security measures and evidence preservation measures against research interference and secret leaks by retirees. Therefore, it is said that frozen samples are prepared in advance, some are stored by themselves, and the rest are transported to cell banks, other departments or outside contractors that provide storage services for frozen cells, etc. Measures are taken.

  In the consignment storage, it is necessary to ensure the reliability of the frozen sample in all processes related to sample transfer between the requester and the consignee and sample storage in the consignee. In particular, if a frozen sample is subjected to an excessive temperature change during transportation or storage, or is thawed without passing through a proper procedure, cells and tissues are altered or destroyed. Therefore, the frozen sample should be moved in a good condition at extremely low temperature without causing a temperature change, and the frozen sample in consignment storage can be returned to the consignor in good condition at the desired timing. Is required. In addition, because the specifications of the cryoboxes used by the workers requesting consignment storage vary widely, the cryoboxes can be placed in a cryopreservation container or deep freezer under cryopreservation conditions using a predetermined unified work procedure. There is a need to be able to transport and store. Furthermore, it is also required to prevent accidents due to sample mis-conveying during transfer and to conceal information on the frozen sample itself from the operator.

  Therefore, the applicant must ensure that the worker who performs consignment storage transports and stores the cryoboxes with different specifications to the cryopreservation container or deep freezer under cryopreservation conditions according to a predetermined unified work procedure. Proposing new means for transporting and storing cryoboxes that can prevent accidents due to sample misuse and keep information about frozen samples themselves from relevant workers. (See Patent Document 1).

  Specifically, cryoboxes with different specifications can be transported and stored in a cryopreservation container or deep freezer under cryopreservation conditions easily and quickly using a predetermined unified work procedure. A box portion for storing a cryobox having a top surface opened and a cryobox take-out slit on the side surface and / or a cryobox push-up opening on the bottom surface, and an openable / closable covering the top surface of the box Proposing a cryobox transport and storage container characterized by having a lid, and further having a number of holes in the side and bottom of the box and the top of the lid A container for carrying and storing a cryobox, and a back side portion of the extension part on the left and right side surfaces of the lid part, the extension part covering the box part on the front side and the left and right side surfaces. A cryobox transport and storage container characterized in that the left side surface portion of the box portion and the upper portion on the back side of the right side surface portion are openably and closably connected. Further, the extension portion is optionally hooked with a finger hanging extension portion. It has been proposed to provide a cryobox transport and storage container characterized in that it is provided with a finger hook portion in which the distal end portion of the extension portion is slightly bent outward.

  These cryobox transport and storage containers are preferably excellent in thermal conductivity and free from corrosion so that the cryobox can be quickly kept at a very low temperature and the cryobox and the frozen sample stored therein can be prevented from being damaged. Since it is made of metal such as stainless steel, the total weight of things to be transported and stored is increasing.

  And in addition to the above-mentioned device for carrying and storing the cryobox, it is possible to open and close the cryobox carrying and storage container that is cooled to an extremely low temperature even more easily and quickly even when using a cryoglove. In particular, the extension portion is provided with a finger-hanging extension portion on the left or right side of the front center portion. A container for carrying and storing the cryobox, and further comprising a convex part or a concave part projecting toward the box part on the front center part of the extension part of the lid part, the front side of the left side part and the front side of the right side part, the convex part Alternatively, the front surface, the left side surface, and the right side surface of the box portion corresponding to the concave portion have a convex portion protruding toward the box portion side or a concave portion engaging with the concave portion or a convex portion protruding toward the lid portion. It proposes to cryo boxes transport and storage container for. Furthermore, as a device for facilitating individual identification of each cryobox transport and storage container while concealing information on the frozen sample itself, an insertion port of the individual identification label affixing plate and the individual are further provided on the front portion of the box portion. It has been proposed to provide a container for transporting and storing a cryobox characterized by having an individual identification label display section provided with an identification label display window.

  Since these cryobox transport and storage containers have asymmetrical structures to improve workability at extremely low temperatures, the weight balance of the transported and stored items is slightly biased.

  Moreover, since each cryobox transport and storage container described in Patent Document 1 stores the cryobox inside the container, the outer size is larger than that of the cryobox. Therefore, it is necessary to store these cryobox transport and storage containers in a metal rack that has a larger outer dimension than the rack that stores the conventional cryobox.

  The cryobox transport and storage container can be transported at a cryogenic temperature of about -150 ° C by placing an adsorbent that adsorbs liquefied nitrogen and a vacuum heat insulating layer after storage in a metal rack. It is stored in a dry sipper which is a frozen sample transport container. Thereafter, the dry sipper is transported between a cryopreservation requester and a consignee by a delivery vehicle such as a truck and consigned and stored.

Japanese Patent Application No. 2016-120269

  As described above, the cryobox transport and storage container that stores the cryobox in which the frozen sample is stored is stored by being stacked on a metal rack, and then stored in a dry sipper that is a frozen sample transport container. Stored and transported while maintaining temperature conditions at cryogenic temperatures. Dry sippers are transported by trucks and other transport vehicles from the requester to the remote requester, but some frozen samples are easily damaged, such as glass ampules. Measures are taken such as storing in a hard case, using a dedicated delivery vehicle, or placing it on a vibration reduction device so that it is less susceptible to vertical vibrations while driving on the road.

  By the way, the dry shipper used for transportation is repeatedly used. In particular, the number of times of use is extremely large in business use in storage service such as frozen cells. Therefore, in order to confirm that the operation of transport work using conventional cryoboxes, racks and dry sippers has been carried out stably over a long period of time, the state of the cryoboxes and racks in which frozen samples and frozen samples are stored are checked. In addition to continuous confirmation, the dry sippers used repeatedly were investigated for dry sippers used in various departments to confirm the inner wall state of the storage unit.

  As a result, it was confirmed that in some dry sippers that have been operated for a long time, some rubbing marks and striking marks are assumed on the inner wall of the storage section, which are assumed to be due to racks and cryoboxes. In order to protect the frozen sample, it is necessary to consider multiple ways by using a special delivery vehicle, storing the dry shipper in a hard case for transportation, and placing it on a vibration reduction device. Even considering this, it was unexpected.

  Therefore, a pressure measurement film that develops color according to the applied pressure was installed on the inner wall of the dry sipper housing, and we checked the presence or absence of contact between the rack and the inner wall. The rack is moved back and forth from a predetermined position and rotated by a rotation moment generated in the left or right rotation direction when the delivery vehicle is turned left and right. It has been clarified that the corners of the metal rack may come into contact with the inner wall of the storage part of the dry shipper, or the cryobox may partially protrude from the rack and come into contact with the inner wall of the storage part of the dry shipper. In particular, the cryobox does not necessarily contain a sample so as to maintain the weight balance, and when the weight balance is lost, contact is likely to occur.

  Such rubbing marks and striking marks caused by load fluctuations in the front-rear direction, generation of rotational moments in the left-right direction, and uneven weight balance do not immediately change the performance of the dry shipper, There is a possibility that the cryogenic holding function of the inner wall of the dry sipper may be impaired by applying a stronger impact or generating scratch marks or blow marks for a long time.

  For frozen samples such as frozen cells stored in a cryobox, if the temperature rises even once and the sample melts, or the components that make up cells and tissues are denatured due to temperature fluctuations, the reliability of the frozen sample Will be lost. For this reason, it must be strictly avoided that there is a risk that the cryogenic temperature holding function of the inner wall is impaired, or that the temperature fluctuation is caused by the actual function being impaired. Considering this point, in the operation of a contracted storage service for frozen cells and the like that requires particularly high reliability, it is necessary to perform more careful work so that such scratches and blow marks do not occur. . Further, when the above cryobox transportation and storage container proposed by the applicant is used, the outer dimension is larger than that of the cryobox, and the rack for storing it is larger than the conventional rack. . On the other hand, the size of the storage portion of the dry shipper does not change, and the gap between the rack and the inner wall is reduced. Therefore, the operator must work more carefully not to touch the inner wall when storing the larger rack containing the cryobox transportation and storage container proposed by the applicant in the storage part of the dry shipper. Need to proceed.

  However, the worker always wears a cryoglove to prevent any increase in the temperature of the frozen sample kept at a very low temperature. For this reason, it is difficult to carry out work even under normal operating methods. However, if the work procedure is changed more carefully, it becomes more complicated, and it takes time and may cause temperature fluctuations. Problems arise. Therefore, the cryobox can be stored in the rack quickly and easily while maintaining the quick and reliable workability in an environment where cryogenic conditions are maintained while wearing the cryoglove, and the rack can be quickly and easily dried. While being stored in the storage part of the sipper, it is necessary to devise a new device so that the inner wall of the storage part of the dry sipper will not be rubbed or blown by a cryobox or rack during transportation. It became clear.

  Furthermore, as described above, the cryobox transportation and storage container proposed by the applicant has an uneven weight balance as a result of improvements in workability at cryogenic temperatures. Therefore, each time the delivery vehicle is accelerated or decelerated, a load is applied in the front-rear direction, and when the delivery vehicle turns to the left or right, a rotation moment in the left rotation direction or right rotation direction is generated, so that the rack is more in a predetermined position. It is easy to move back and forth and rotate. Considering the fact that rubbing marks and striking marks are generated even when a normal size rack containing a general-purpose cryobox is used, the applicant proposed that the weight balance is slightly larger than that. If a larger rack storing the cryobox transportation and storage container is used, it is considered that scratch marks and striking marks are more likely to occur.

  Therefore, even when using the cryobox transport and storage container proposed by the applicant, the container is securely held in the dry sipper storage part, and the cryobox transport and storage container or the like is placed on the inner wall of the dry sipper storage part. It has been urgently desired not to generate scratch marks or striking marks derived from the rack in which it is stored.

  Therefore, the problem to be solved by the present invention is that the cryobox and the cryobox can be transported quickly and easily to the rack for the dry sipper stored in the dry sipper and kept at an extremely low temperature while the cryoglove is used by the operator. Storage container or storage container can be quickly and easily removed from the rack after storage, and the dry sipper rack and the cryobox and cryobox storage and storage It is an object of the present invention to provide a new dry sipper rack that can reduce temperature fluctuations of a storage container and a frozen sample stored in a cryobox as much as possible.

  In addition, the problem to be solved by the present invention is that a dry sipper rack held at an extremely low temperature can be quickly and easily stored or taken out from the dry sipper while the operator uses a cryoglove. To provide a new rack for dry sippers that can reduce temperature fluctuations of frozen samples stored in the cryobox as much as possible And

  A further problem to be solved by the present invention is that the cryobox and the cryobox transport and storage container do not protrude from the rack during transport, and the rack does not contact the inner wall of the dry shipper. A new rack for dry sippers that can carry out the operation of transporting frozen samples held at extremely low temperatures by dry sippers over a long period of time without causing damage to the inner walls of the dry sippers. It is an issue to provide.

  A first means of the present invention for solving the above problems is a metal dry sipper rack having a storage section for storing a cryobox or a cryobox transport and storage container, and the front of the rack. Is provided with a storage port for inserting or removing a cryobox or a cryobox transport and storage container, and the storage port is provided with a lid member capable of maintaining a closed state, and the left side surface and the right side of the rack. The inner wall of the storage part of the dry sipper is pressed against the wall surface of the surface so that the rack is fixed to the storage part of the dry sipper and is bent in an arc shape and one end is fixed to the upper part of the side surface of the rack. A leaf spring having an end fixed to the lower part of the side surface of the rack is disposed, and a gripping portion erected on the upper part of the flat surface of the rack. It is a wrapper for the rack.

  The second means of the present invention for solving the above problems is characterized in that a plurality of storage ports for inserting or extracting the cryobox or the cryobox transport and storage container are arranged in a plurality of stages. 1 is a dry sipper rack of one means.

  The third means of the present invention for solving the above-mentioned problems is the first or second means characterized in that the lid member capable of holding the closed state has a hinge with a spring. This is a dry sipper rack.

  The fourth means of the present invention for solving the above-mentioned problems is characterized in that a finger hook portion is provided in an opening portion of the lid member capable of holding the closed state. The dry sipper rack of any one of the means.

  The fifth means of the present invention for solving the above-mentioned problems is characterized in that the finger hook portion is in a state where the lid member is bent outward from the storage portion by 10 to 60 degrees. The dry sipper rack of any one of the first to fourth means.

  According to a sixth means of the present invention for solving the above-mentioned problem, the lid member capable of holding the closed state does not shield the individual identification label display unit arranged in the cryobox transportation and storage container. A dry sipper rack according to any one of the first to fifth means, characterized in that it is arranged.

  The seventh means of the present invention for solving the above-mentioned problems is that the dry sipper rack is provided on the left side wall, the right side surface, the back surface, the bottom surface of the rack wall surface, the cryobox or cryobox transport and storage container storage unit bottom surface. The dry sipper rack according to any one of the first to sixth means, which has an opening in any one of them.

  In order to store a conventional rack in a dry sipper storage part held under cryogenic conditions, it is necessary to perform the storage work with sufficient consideration so that the corners of the bottom of the rack do not collide with the inner wall of the dry sipper storage part. . On the other hand, the dry sipper rack according to the means of the present invention is curved in a circular arc shape on the left side surface and the right side wall surface of the rack, with one end fixed to the upper part of the rack side surface and the other end fixed to the lower part of the rack side surface. Since the leaf springs are arranged, the corner of the dry sipper rack does not collide with the inner wall of the storage part of the dry sipper at the time of storage, and the damage is not caused. The dry sipper rack according to the means of the present invention is inserted into the dry sipper storage part held under cryogenic conditions while inserting the arcs of leaf springs arranged on both sides of the rack along the inner wall of the storage part. It is possible to store it very easily and quickly only by operation. Furthermore, the dry sipper rack, which is inserted and stored in the dry sipper storage part while inserting the arc of the leaf spring along the inner wall of the storage part, is stored in the dry sipper by two leaf springs arranged on the left side and the right side of the rack. Since the inner wall of each part is pressed and stretched, the corner of the wall surface of the dry sipper rack does not come into contact with the inner wall of the dry sipper storage part, and the dry sipper rack is stable at the central part in the dry sipper storage part. Thus, it is possible to keep the held state.

  In addition, the cryobox or cryobox transport and storage container is heavier than the frozen sample being stored, and the weight balance is biased. If the load is applied, or if a load is applied in the counterclockwise or clockwise direction by turning left and right, it will move or rotate and hit the inner wall in the storage part of the dry shipper. However, in the dry sipper rack according to the means of the present invention, the elasticity of the two leaf springs arranged on the left side surface and the right side surface of the rack remains sufficiently large even after being stored in the storage part of the dry sipper. Since the load applied by the elasticity of the held leaf spring is relieved, the dry sipper rack does not move or rotate, and the dry sipper rack is stably stored. Since it continues to be held at a predetermined position in the unit, a situation in which the corner of the wall surface of the dry sipper rack contacts the inner wall in the storage unit of the dry sipper does not occur. Therefore, the dry sipper rack according to the means of the present invention causes damage to the inner wall of the dry sipper even if the dry sipper is continuously transported for a long period of time in the operation of a contracted storage service for frozen cells or the like that requires particularly high reliability. There is no concern, and the long-term reliability of cryoboxes that store frozen samples kept at extremely low temperatures or the transportation of cryoboxes and storage containers is greatly improved.

  Further, according to the means of the present invention, the gripping part fixed in a standing state is arranged on the upper part of the flat surface of the dry sipper rack, so that the worker wears a cryoglove that is a thick glove. Even in this case, it is possible to easily grasp the gripping portion that is already erected without causing the gripping portion to be caused by a thick cryoglove. The dry sipper rack according to the means of the present invention can hold the stationary and fixed gripping portion firmly with the cryoglove, so that the cryobox or the cryobox transport and storage container with an unbalanced weight is stored. Even so, the rack is hard to tilt and stable, and the risk of hitting various places is greatly reduced.

  Still further, the dry sipper rack of the means of the present invention has two leaf springs on the left and right side wall surfaces, so that it has a gripping portion erected with either the left or right hand, With the other hand, it is possible to support and support one of the leaf springs arranged on the left or right side wall surface, so that the dry sipper rack can be moved with a more stable posture, Can be stored in the storage part of the dry shipper. And since the leaf springs arranged on the left and right side walls are held and supported, an accident in which the operator directly contacts the rack body to transfer heat is prevented, and the cryobox or cryobox storing the frozen sample It is possible to carry out the loading / unloading operation of the dry shipper rack easily, stably and quickly while keeping the temperature change of the container for transportation and storage to a minimum. In addition, since a stable work is possible regardless of the dominant hand of the worker, it is easy to formulate a standard work procedure.

  Furthermore, the lid member after the cryobox or the cryobox transport and storage container is stored in the closed state by the lid member that can be kept closed by the means of the present invention or the hinge with spring. Because it can be held, the stored cryobox or cryobox transport and storage container pops out by applying a load in the front-rear direction during transfer work or adding a load in the counterclockwise or clockwise direction by turning left and right And the inner wall of the storage part of the dry sipper in which the dry sipper rack is stored is impacted by the cryo box of the dry sipper rack or the container for carrying and storing the cryo box. It is possible to greatly reduce the risk of injury.

  The opening of the lid member that can hold the closed state is provided with a finger hook portion by bending the lid member outward from the storage portion by 10 to 60 degrees. Even when wearing a glove that is a thick glove, it is possible to quickly open and close the lid member by placing a finger of the thick glove on the finger hook part, for cryobox or cryobox transportation and storage It is possible to minimize the temperature change from the extremely low temperature of the container.

  In addition, in the means of the present invention, the dry sipper rack has an opening on either the left side, the right side, the back, the bottom rack wall, the cryobox or the cryobox transport and storage container storage unit bottom, A cryogenic atmosphere such as air or nitrogen gas in the dry sipper flows in quickly, and the cryobox or cryobox transport and storage container stored in the storage part of the dry sipper is quickly kept in a cryogenic state. It is possible to keep temperature changes from extremely low temperatures to a minimum.

  Further, the means of the present invention is arranged so that the lid member capable of holding the closed state does not shield the individual identification label display portion arranged in the cryobox transportation and storage container. The person in charge of the storage container transfer destination can easily see and identify the individual identification label display section while the cryobox transportation and storage container is stored in the dry shipper rack. In addition, the cryobox transport and storage containers can be moved more quickly to the planned storage location for cryopreservation containers and deep freezers to minimize temperature changes from cryogenic temperatures.

  And by means of the present invention, regardless of the level of proficiency of the workers who perform consignment storage, the dry sipper rack and the dry sipper were used extremely easily and quickly while keeping the temperature change from extremely low temperatures to a minimum. It is possible to carry out cryo-boxes that store frozen samples or to transport cryo-boxes and to transfer containers for storage, so it is easy to formulate unified work procedures for consigned storage work using dry sipper racks and dry sippers. At the same time, education and training for workers are facilitated, and related costs such as fixed costs for transportation and storage work are reduced.

It is a perspective view of the rack for dry sippers according to the embodiment of the present invention.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments for carrying out the present invention will be described as appropriate with reference to the drawings.

<Material for dry sipper rack>
The material used for the dry sipper rack (1) of the means of the present invention is not particularly limited as long as it is used for a container. Considering that it can withstand storage in a metal, it shall be made of metal.

  The metal to be used is not particularly limited as long as it is used for containers such as stainless steel, aluminum alloy, titanium alloy, copper alloy, etc. However, considering that it can withstand long-term use, it is preferably impact resistance and corrosion resistance. Stainless steel known to be provided with As the stainless steel, an austenitic stainless steel having good workability and weldability is used, and SUS304 is preferably used. A rivet can be used to join the members. In that case, it is preferable to use a copper alloy that is easy to process and easy to maintain strength.

<About shape of rack for dry shipper>
The dry sipper rack (1) according to the present invention has a storage portion (6) for storing a cryobox or a cryobox transport and storage container in front of the rack, and the storage opening is closed. The lid member (3) capable of holding the rack is disposed, and the inner wall of the storage part of the dry shipper is pressed against the left and right side wall surfaces of the rack so that the rack is stored in the storage part of the dry shipper. A leaf spring (4), which is bent in an arc shape and is fixed to the upper part of the rack side surface and fixed to the lower part of the rack side surface, is arranged on the upper side of the rack plane. It is assumed that the gripping portion (5) is arranged (FIGS. 1 and 3 to 8). The dry sipper rack (1) may be provided with a plurality of storage portions (6) in the vertical direction in accordance with the size of the cryobox to be stored or the container for carrying and storing the cryobox.

  The inside dimensions of the storage part (6) of the dry sipper rack (1) are used for insertion and removal of a cryobox for storing inside and a cryobox carrying and storage container (8) capable of storing the cryobox inside. It may be set to be slightly larger than the outer size so that it does not cause any trouble. By not increasing the internal dimensions more than necessary, the gap between the dry sipper rack and the cryo box and the cryo box transport and storage container that can store the cryo box is reduced, and the room temperature outside air into the dry sipper is reduced. As a result, it is possible to minimize the temperature change that occurs in the frozen sample, the cryobox and the cryobox transport and storage container generated during the transfer from the frozen storage container to the dry shipper.

  For example, in a rack having a height of about 247 mm, a cryobox having a height of 50 mm to 58 mm or a container for carrying and storing a cryobox can be stored in four stages. For example, if the outer dimensions of the cryobox (9) stored inside are 133 mm long × 133 mm wide × 52 mm high, the cryobox transport and storage container has a thickness of about 0.5 mm to 1.4 mm. When SUS304 is used, the outer dimension is 136 mm in length x 136 mm in width x 58 mm in height, so the inner dimension of the storage section (6) of the dry sipper rack (1) is about 3 to 10 mm larger in length and breadth. Preferably, it is set to be about 3 to 5 mm, more preferably 3 mm larger. When the size is set in this way, the time required for the work and the small change in temperature are compatible, and a highly reliable transport work is possible.

  Further, the leaf spring (4) absorbs vibrations that the dry sipper rack receives during transportation work, and has appropriate elasticity, so that the dry sipper can be easily inserted into and removed from the storage unit, and the dry sipper The width is such that the inner wall of the storage part is not damaged. Further, the leaf spring (4) has a width of about 20 to 50 mm, preferably about 30 mm. With this width, when the operator wearing the cryoglove supports the dry sipper rack so that it does not tilt, the operator can easily hold the leaf spring (4) without directly contacting the rack body. As a result, it is possible to carry out the loading / unloading operation of the dry sipper rack easily, stably and quickly while minimizing the temperature change of the cryobox storing the frozen sample or the container for transporting and storing the cryobox. .

  Furthermore, even if the cryoglove is still attached, the cryobox and cryobox transport and storage containers can be inserted and removed more quickly, and the cryogenic gas in the dry shipper can be quickly removed from the cryobox. In order to obtain the effect that the temperature change of the frozen sample can be kept to a minimum by touching the container and the cryobox transportation and storage container, and further the effect of reducing the weight of the dry sipper rack (1) is exhibited. In addition, an opening (7) may be provided on the left, right, rear, and bottom rack wall surfaces of the dry sipper rack (1), and the cryobox or cryobox transport and storage container storage unit bottom surface (FIG. 1). 3 to 8). Larger openings on the left, right, and back sides make it easier to push out the cryobox and cryobox transport and storage container while wearing the cryoglove, while reducing the weight of the dry sipper rack Effect is obtained.

  In addition, a grip portion (5) fixed in an upright state is disposed on the upper surface of the dry sipper rack (1) according to the means of the present invention. Since the grip portion (5) is fixed in an upright state, the grip portion that is quickly set up and fixed can be firmly gripped by the cryoglove. The gripping part (5) has a height of about 50 mm and a width of about 120 mm so as to facilitate the work when the cryoglove is attached, and has a rectangular ring shape, and the central part is appropriately set to a higher height to achieve the cryo-glow. It is preferable that the glove is easily inserted (FIGS. 1, 3 to 6, and 9). In this way, by holding the gripping part (5) upright on the plane of the dry sipper rack (1), a cryobox or a container for transporting and storing the cryobox with an unbalanced weight is stored. In this state, even if the operator lifts the dry sipper rack, the gripping part that is erected and fixed can be firmly gripped by the cryoglove, so the rack is hard to tilt and stable, and there is a risk of hitting various places. It will be greatly reduced.

  In addition, since there is a gripping part (5) that is erected and fixed, hold it with either the left or right hand wearing the cryoglove, and use it with the other hand that is vacant on the left or right side wall. Any one of the arranged leaf springs (4) can be supported and supported, and a working environment for moving the dry sipper rack with a more stable posture by holding both hands is realized. Since stable work can be performed regardless of the dominant hand of the operator, it is easy to determine a standard work procedure.

  Further, the lid member (3) capable of maintaining the closed state of the dry sipper rack according to the means of the present invention uses a spring-equipped hinge (3a), etc. After the storage, it is preferable that the cover member automatically returns to the closed state when the operator releases the hand with the spring-equipped hinge, and the closed state of the cover member is maintained during transportation. As a result, it is possible to prevent an accident in which an unexpected load is applied to the dry sipper rack and the stored cryobox or cryobox transport and storage container is popped out.

  The lid member (3) capable of holding the closed state can be provided with a finger hook portion (3b) as a portion where a finger can be hooked when opening the lid with a cryoglove. This finger hook portion (3b) can be such that the tip end portion of the lid member is bent in a direction outward from the storage portion by 10 degrees to 60 degrees. The hook is improved and the lid member (3) can be easily opened.

  The container for cryobox transportation and storage (8) is provided with an individual identification label display window for displaying an individual identification label for accessing a database in which information on the stored cryobox is recorded. A label display section (8a) is provided.

  Below, the Example which manufactured and used the rack (1) for dry shippers of the means of this invention is shown. The present invention is not limited to these descriptions.

Test example 1
We investigated whether the operation of transportation work using conventional cryoboxes, racks and dry sippers has been carried out stably over a long period of time. First, the frozen sample and the state of the cryobox and rack storing the frozen sample were confirmed. In addition, regarding dry sippers that are used repeatedly, we investigate dry sippers used in various departments and determine the delivery conditions (whether a dedicated delivery vehicle is used, whether it is stored in a hard case for transportation, vibration reduction devices, etc. And the inner wall state of the dry sipper storage part was confirmed.

  As a result, it was confirmed that in some dry sippers that have been operated for a long time, some rubbing marks and striking marks are assumed on the inner wall of the storage section, which are assumed to be due to racks and cryoboxes. For protection of frozen samples, it is also confirmed for those that consider multiple things by using a dedicated delivery vehicle, storing the dry shipper in a hard case for transportation, and placing it on a vibration reduction device etc. There was something.

Test example 2
A test was conducted to confirm at what timing the scratches and striking marks assumed to be due to the rack and cryobox were generated.

  A dry sipper was prepared, and a pressure measurement film capable of visualizing and quantifying the surface pressure distribution was mounted on the entire inner wall portion of the inner wall portion in a red color depending on the applied pressure. Subsequently, the test which accommodates the rack which stored the cryobox conventionally used for the dry shipper was repeated.

  As a result, it was confirmed that the color of the rack was in contact with a part of the pressure measurement film mounted on the inner wall of the dry sipper. It has become clear that the rack may come into contact with the inner wall when stored in the dry shipper.

Test example 3

  In addition, when the above-mentioned dry sipper is delivered over a long distance and a special delivery vehicle is used, the dry sipper is stored in a hard case for transportation, or installed on a vibration reducing device for transportation. The delivery was carried out in different ways, and the state of the film on the inner wall was confirmed.

  As a result, it was confirmed that the color of the rack was in contact with a part of the pressure measurement film mounted on the inner wall of the dry sipper. Even with special considerations such as the use of a dedicated delivery vehicle, the use of a hard case for transportation, and the use on a vibration reduction device, the color that appears to be in contact with the corner of the rack is part of the pressure measurement film. Confirmed in the department.

  As a result, the state of contact was confirmed in detail. From the state of the contact mark (colored state), a load was applied in the front-rear direction every time the delivery vehicle was accelerated and decelerated. Alternatively, when a rotational moment in the clockwise direction is generated, the rack moves forward or backward from a predetermined position or rotates, so that the corners of the metal rack come into contact with the inner wall of the dry sipper storage unit, It became clear that a part of the cryobox jumped out and contacted the inner wall of the dry sipper storage. It was also revealed that contact is likely to occur when the weight balance of the cryobox is broken.

Test example 4
Therefore, a dry sipper rack provided with a new device was produced, and a test was conducted to confirm whether the problem can be avoided.

  As Example 1, a dry sipper rack (1) according to the means of the present invention was produced. SUS304 with a plate thickness of 1.0 mm is used as the metal plate, the outer dimensions of the rack are 145 mm long x 145 mm wide x 247 mm high, and the inner dimensions are 144 mm long for storing the cryobox or cryobox transport and storage container. It is assumed that there are four vertical storage sections of 144 mm in width and 61 mm in height, and the rack storage opening has a length of 75 mm on the right side of each storage opening as shown in FIGS. Then, a lid member capable of holding the closed state of SUS304 having a width of 21 mm is disposed, and a leaf spring of SUS304 having a width of 30 mm is used on the left side surface and the right side wall surface of the rack, and FIGS. As shown in FIG. 8, when the inner wall of the dry sipper storage part is pressed, the rack is bent in an arc shape and one end of the rack is fixed to the dry sipper storage part. A leaf spring fixed at the upper part of the rack side and having the other end fixed at the lower part of the side of the rack is provided. The upper part of the flat surface of the rack has a height of 50 mm and a width of 120 mm as shown in FIGS. Thus, a SUS304 gripping part having a square ring shape with a raised central part was erected, and the s304 was fixed with a fixture or the like that erected and fixed the gripping part. Openings were provided on the left side, right side, back, bottom rack wall, cryobox or cryobox transport and storage container storage as shown in FIGS.

  As Example 2, the above-mentioned dry sipper rack (1) was manufactured such that the lid member capable of holding the closed state further had a spring-equipped hinge (3a).

  As Example 3, in the dry sipper rack (1), it is assumed that a finger hook portion is further provided in the opening portion of the lid member capable of holding the closed state, as shown in FIGS. A member was manufactured in a state where the member was bent outward from the storage portion.

  As Example 4, in the dry sipper rack (1), the lid member (3) capable of holding the closed state does not shield the individual identification label display unit arranged in the cryobox transportation and storage container. As shown in FIGS. 2-8, the thing which will be in the state which has arrange | positioned the cover member (3) above the individual identification label display part was manufactured.

  As a comparative example 5, the inner wall of the storage part of the dry shipper is pressed against the left and right side walls of the rack so that the rack is fixed to the storage part of the dry shipper in an arc shape. A dry sipper rack having no leaf spring (4) with one end fixed to the upper part of the rack side surface and the other end fixed to the lower part of the rack side surface was produced.

  As Comparative Example 6, a dry sipper rack without a lid member (3) capable of holding a closed state was produced.

  Further, a cryobox transport and storage container (8) for storage in the dry sipper rack of each of the above Examples and Comparative Examples was manufactured. As the metal plate, SUS304 having a plate thickness of 1.0 mm was used. The outer dimension of the lid part was 138 mm in length, 138 mm in width, 9.8 mm in height, and the box part had an inner dimension of 134 mm in length, 134 mm in width, and 57.8 mm in height. Things were manufactured. The left side surface portion and the right side surface portion were provided with a cryobox take-out slit having a lower side of 65 mm × upper side 30 mm × height of 40 mm, and a cryobox push-up opening having a diameter of 50 mm was provided on the bottom surface. As shown in the figure, a large number of holes were provided in the top surface of the lid portion, the left and right side surface portions, and the bottom surface portion of the box portion. The extension part for finger hooks provided in the extension part of the lid part was set to have a width of 20 mm and the center thereof at a position of 61 mm from the left of the front part and 75 mm from the right. Further, the extending part of the lid part was provided with a convex part and a concave part so as to be engaged with each other at three locations on the front center part, the front side of the left side part, and the front side of the right side part. The lid part is connected to the back side part of the bent extension part on the left side part and the right side part thereof, and the upper part on the back side of the left side part and the right side part of the box part so as to be opened and closed. . And the individual identification label display part was arranged in the lower left part of the box part front.

  In addition, a cryobox made of polycarbonate and paper that can be stored in a cryobox transport and storage container and has an outer dimension of 133 mm in length, 133 mm in width, 52 mm in height, and 81 1 mL to 2 mL sample tubes was prepared. The cryoboxes were prepared by packing 81 1 mL tubes containing samples, and 45 by collecting and packing 45 tubes in one place and providing a weight balance.

  Cryobox transport and storage container storing a cryobox packed with 81 sample tubes, or a cryobox storing a cryobox with a biased weight balance by collecting and packing 45 sample tubes in one place The containers for transportation and storage were respectively stored in the dry sipper racks of the above Examples and Comparative Examples. In addition, each of these racks for dry sipper was housed in a dry sipper, and the state of the pressure measurement film mounted on the inner wall was confirmed. In addition, these dry sippers are delivered over long distances with different conditions, such as when using a dedicated delivery vehicle, storing the dry sippers in a transport hard case, or installing them on a vibration reduction device. In each case, the state of the film on the inner wall was confirmed.

  As a result, the inner wall of the storage portion of the dry sipper is pressed against the left and right side walls of the rack so that the rack is bent in an arc shape to fix the rack to the storage portion of the dry sipper. In the case of the rack of Comparative Example 5 that does not have a leaf spring (4) that is fixed to the upper part of the rack side surface and the other end is fixed to the lower part of the rack side surface, the pressure measurement film is colored when inserted into the dry shipper. From this situation, it was confirmed that the rack was slanted when inserted into the dry shipper, and the corners of the rack were in contact. Also, even if the pressure measurement film does not develop color when inserted into a dry shipper, when it is delivered over long distances, the pressure measurement film will develop color even when using a special delivery vehicle, a transport hard case, or a vibration reduction device It was confirmed that there is. Check the running conditions of the colored ones. When a strong load change in the front-rear direction occurs when starting and stopping, or when turning left and right, a left-right rotational moment is generated, especially when the weight balance is biased. It was confirmed that the rack containing the cryobox gradually rotated and generated and rubbed on the inner wall of the dry shipper, and the corners of the rack were in contact.

  Further, in Comparative Example 6 using the dry shipper rack that does not have the lid member (3) capable of holding the closed state, a special delivery vehicle, a hard case for transportation, and a vibration reducing device are used for long distance delivery. In addition, it was confirmed that the pressure measurement film may develop color. Check the running condition of the colored one, and if a strong load fluctuation in the front-rear direction occurs when starting and stopping, or when turning left and right, a left and right rotational moment is generated and the cryobox is stored. It was confirmed that some of the racks jumped out of the racks and caused a slash on the inner wall of the dry shipper.

  On the other hand, when the dry sipper rack of Examples 1 to 4 having the structure of the means of the present invention was used, the dry sipper rack was fixed in an upright state when inserted into the dry sipper. It was easy to hold the gripping part firmly with either the left or right hand wearing a cryoglove. In addition, with the other hand wearing the cryoglove, it is possible to lightly support and support a leaf spring that is bent in an arc shape, one end fixed to the upper part of the rack side and the other end fixed to the lower part of the rack side. It was. Therefore, the dry sipper rack is not inclined obliquely, but the arc of the leaf spring in which one end is fixed to the upper part of the rack side and the other end is fixed to the lower part of the rack side is stored in the dry sipper. It can be inserted straight into the storage part of the dry sipper while being along the part, and the corner of the dry sipper rack does not collide with the inner wall of the dry sipper to form a scratch mark.

  Further, before insertion into the dry sipper, the arc-shaped leaf spring is in an expanded state (a state having a width of AA in FIG. 9), but when inserted along the dry sipper storage portion, The width of the storage portion is pushed and reduced to the width of the storage portion of the dry shipper (the state having the width of BB in FIG. 9), and the inner wall of the storage portion of the dry shipper is caused by the elasticity of the flattened leaf spring. Since it is pressed, the dry sipper rack is firmly fixed to the storage part of the dry sipper, and the inner wall is supported by the surface of the leaf spring, so that the inner wall is not damaged.

  Furthermore, the inner wall of the storage part of the dry shipper leaves a surplus force in the elasticity of the leaf spring even if a load in the front-rear direction is added by long-distance delivery, or a load in the counterclockwise or clockwise direction due to left-right rotation is added. Since the inner wall is supported by the surface of the leaf spring while pressing, the state where the dry sipper rack is firmly fixed to the storage part of the dry sipper is held, and the inner wall of the storage part of the dry sipper is damaged. There was nothing. The weight of the metal cryobox transport and storage container containing a cryobox containing a large number of frozen samples is considerable. However, by using the dry sipper rack according to the means of the present invention, it becomes clear that even if a product having such a weight is stored in the rack and used for transportation, the inner wall of the dry sipper storage part is not damaged. It was. The dry sipper rack according to the means of the present invention may cause damage to the inner wall of the dry sipper even if the dry sipper is continuously transported for a long period of time in the operation of a contracted storage service for frozen cells, which requires particularly high reliability. In addition, it is understood that the long-term reliability of the cryobox or cryobox transporting the cryosample stored in the cryogenic state and the transfer operation of the storage container is greatly improved.

  Furthermore, when the lid member that can hold the closed state has a spring-equipped hinge (3a), the lid is automatically closed by the action of the spring even if one hand of the operator is closed, so that the work can be performed quickly. It was confirmed that there is. Even if the dry sipper rack is slanted, the lid is closed by the action of the spring, preventing the cryobox from popping out.

Test example 5
Furthermore, a test was conducted to confirm the operational status under actual transportation conditions. A dry sipper rack of Examples 1 to 4 was prepared by impregnating an absorbent with liquid nitrogen so that the sample could be transported at a cryogenic temperature in a dry state. The cryobox transport and storage container storing the cryobox storing the sample was stored, and the container was transported with the cryoship attached to the dry sipper.

  As a result, in the embodiment, the gripping part fixed in a standing state is arranged on the top of the flat surface of the dry sipper rack, so that the worker wears a cryoglove that is a thick glove. Even if it is, the gripping part can be firmly gripped with the hand wearing either the left or right cryoglove, and the other hand supports the leaf spring on the left or right side wall. I was able to support it. As a result, an accident in which an operator directly contacts the rack body and transfers heat is prevented. The dry sipper rack according to the means of the present invention is an easy, stable and quick carry-in / out operation of the dry sipper rack while keeping the temperature change of the cryobox or cryobox transport and storage container storing the frozen sample to a minimum. It was understood that it was possible to implement. It was also understood that the standard work procedure can be easily formulated because stable work is possible regardless of the dominant hand of the worker.

  Further, in the third embodiment, the lid member that can hold the closed state is further provided with the finger hook portion, so that the cryobox or the cryobox can be transported from the dry sipper rack held at an extremely low temperature. When the storage container was taken out, the lid member could be easily opened by simply hooking and pulling the finger part of the cryoglove on the finger hook part without touching the cryobox or the cryobox transport and storage container. This makes it possible to minimize the temperature change of the cryobox or cryobox transport / storage container that stores the frozen sample, so that the dry sipper rack can be carried in and out easily and stably. It was understood that this was possible.

  And the thing of Example 4 is a lid member above the individual identification label display part as shown in FIGS. 2-8 so that the individual identification label display part arranged on the container for cryobox transportation and storage may not be shielded. (3) Because it is arranged, the information displayed on the individual identification label display part attached to the cryobox transport and storage container without taking out the cryobox transport and storage container from the dry shipper rack It was understood that it was possible to confirm, and it was possible to quickly carry out the loading and unloading work of the dry sipper rack.
