The invention provides a kidney transplantation specimen storage device.
In an embodiment of the present invention, as shown in fig. 1 to 5, the kidney transplant specimen storage device includes a housing 10, a piston cylinder 20, and an adjustment device 30.
Specifically, the box 10 has a storage cavity 11 for storing a freezing fluid, which is a liquid meeting the temperature requirement for refrigerating the specimen, and may be water, oil or other liquid. Further, the reservoir 11 forms a piston port 12 on the surface of the case 10, and the bore of the piston port 12 is smaller than the inner diameter of the reservoir 11. That is, the reservoir chamber 11 may communicate with the environment outside the housing 10 through the piston port 12. It should be noted that in some embodiments, handles, wheels, etc. may be provided on the housing 10 for ease of transport, which are not shown in this embodiment.
Specifically, the piston cylinder 20 includes a partition head 21 and a storage cylinder 22.
The partition head 21 is movably disposed in the liquid storage chamber 11, and partitions the liquid storage chamber 11 into a first chamber 111 and a second chamber 112 that are not communicated with each other, the first chamber 111 has a piston port 12, wherein the volumes of the first chamber 111 and the second chamber 112 change with the movement of the partition head 21. Specifically, the partition head 21 is movable in the longitudinal direction of the reservoir 11, and the volumes of the first chamber 111 and the second chamber 112 are changed with the movement of the partition head 21, but the sum of the volumes of the first chamber 111 and the second chamber 112 is not changed. In actual use, the first cavity 111 and the second cavity 112 both store refrigerating fluid, and since the first cavity 111 and the second cavity 112 are not communicated with each other, the partition head 21 can be driven to move in the fluid storage cavity 11 by changing the volume of the refrigerating fluid in the first cavity 111 and the second cavity 112. Specifically, when the freezing liquid in the first cavity 111 increases and the freezing liquid in the second cavity 112 decreases, the dividing head 21 moves away from the piston port 12; when the cooling fluid in the first chamber 111 decreases and the cooling fluid in the second chamber 112 increases, the dividing head 21 moves in a direction to approach the piston port 12.
One end of the storage cylinder 22 is arranged on the separating head 21, the other end extends out of the piston port 12, the storage cylinder 22 is in sealing fit with the piston port 12, an accommodating cavity 221 for storing a specimen is formed in the storage cylinder 22 in a hollow mode, and a taking and placing opening 222 is formed in one end, back to the separating head 21, of the storage cylinder 22 in the accommodating cavity 221. Wherein the storage cylinder 22 has a first position for taking and placing the specimen and a second position for refrigerating the specimen, and the length of the storage cylinder 22 extending out of the piston port 12 in the first position is greater than the length of the storage cylinder 22 extending out of the piston port 12 in the second position. Specifically, when the cartridge 22 is in the first position, the health care provider may place a kidney transplant specimen in the cartridge 22 or remove a specimen from the cartridge 22; when the storage cylinder 22 is at the second position, the refrigerating fluid in the first cavity 111 surrounds the storage cylinder 22, so that the accommodating cavity 221 is at a low temperature environment to store the specimen. The length of the storage cylinder 22 extending out of the piston port 12 in the first position is greater than the length of the storage cylinder 22 extending out of the piston port 12 in the second position, which means that no matter the storage cylinder 22 is in the first position or the second position, a part of the storage cylinder 22 always extends out of the piston port 12 to ensure that the cooling liquid in the first cavity 111 does not overflow from the piston port 12.
The adjusting device 30 is used for controlling the volume of the freezing liquid in the first cavity 111 and the second cavity 112, so as to drive the storage cylinder 22 to move between the first position and the second position through the separating head 21. Specifically, the adjusting device 30 can increase or absorb the freezing liquid in the first cavity 111 and the second cavity 112 to drive the partition plate to move in the liquid storage cavity 11, so as to drive the storage cylinder 22 to move between the first position and the second position. Specifically, when the partition head 21 moves in a direction to approach the piston port 12, the storage cylinder 22 can move from the second position to the first position; when the partition head 21 is moved in a direction away from the movable opening, the cartridge 22 can be moved from the first position to the second position.
It can be understood that, the kidney transplantation sample storage device of this application technical scheme, through set up piston cylinder 20 in stock solution chamber 11, this piston cylinder 20's division board divides stock solution chamber 11 into first cavity 111 and second cavity 112, this piston cylinder 20's storage cylinder 22 then can be used to deposit the sample, this application still controls the capacity of freezing liquid in first cavity 111 and second cavity 112 through adjusting device 30 to the drive division board removes in stock solution chamber 11, and the removal of division board can drive storage cylinder 22 and remove, so, medical personnel alright get when storage cylinder 22 is in the first position and put the sample, and storage cylinder 22 then can be used to preserve the sample when being in the second position. Therefore, the refrigerating fluid in the liquid storage cavity 11 can provide a refrigerating environment for the preservation of the specimen when the storage tube is located at the second position, and can also provide power for the movement of the storage cylinder between the first position and the second position so as to facilitate the storage and taking of the specimen. In addition, the storage barrel can be moved back into the storage cavity 11 with the specimen when in the second position, thereby being beneficial to improving the safety of specimen preservation. To sum up, the kidney transplantation sample storage device of this application has that the sample is got and is put convenience, sample and deposit advantages such as security height.
Optionally, the dividing head 21 is provided with a first sealing ring (not shown) at its outer periphery to enhance the sealing performance between the first cavity 111 and the second cavity 112.
Optionally, the peripheral wall of the piston port 12 is provided with a second sealing ring to enhance the sealing of the fit between the reservoir 22 and the piston rod.
Specifically, the cavity wall of the liquid storage cavity 11 is provided with a first infusion port 113 communicated with the first cavity 111 and a second infusion port 114 communicated with the second cavity 112. Among them, since the volumes of the first chamber 111 and the second chamber 112 are variable, the first infusion port 113 and the second infusion port 114 are provided at both ends of the reservoir chamber 11 in order to facilitate the addition of the refrigerant fluid into the first chamber 111 and the second chamber 112.
Alternatively, to facilitate the addition of chilled fluid to second chamber 112 when cartridge 22 is in the second position, a second fluid port 114 may be provided on a side of reservoir chamber 11 opposite piston port 12.
Specifically, the regulating device 30 includes a refrigerant fluid container 31, a first fluid line 32, a second fluid line 33, and a power pump 34. Wherein,
the refrigerating fluid container 31 is used for storing refrigerating fluid;
one end of the first infusion tube 32 is communicated with the first infusion port 113, and the other end is communicated with the refrigerating fluid container 31;
one end of the second infusion tube 33 is communicated with the second infusion port 114, and the other end is communicated with the second infusion port 114;
Specifically, during actual use, the refrigerant liquid container 31, the first liquid transport tube 32, the second liquid transport tube 33, the first cavity 111, and the second cavity 112 are all filled with refrigerant liquid. If the power pump 34 is connected to the first liquid pipe 32, in the actual use process, if the storage cylinder 22 needs to move from the first position to the second position, the power pump 34 can pump the refrigerant liquid in the refrigerant liquid container 31 to the first cavity 111 through the first liquid pipe 32, and at this time, the refrigerant liquid in the second cavity 112 flows to the refrigerant liquid container 31 through the second liquid pipe 33. If it is required to move the storage cylinder 22 from the second position to the first position, the power pump 34 may pump the refrigerating fluid in the first cavity 111 into the refrigerating fluid container 31, and at this time, the refrigerating fluid in the refrigerating fluid container 31 overflows to the second cavity 112 through the second fluid pipe 33.
It can be understood that, with the above structure, the adjustment of the volumes of the freezing liquids in the first chamber 111 and the second chamber 112 can be realized by only one power pump 34, which is beneficial to simplify the structure of the adjusting device 30 and reduce the cost of the adjusting device 30.
