Description

Technical Field

[0001] This utility model belongs to the field of embryo storage technology, specifically relating to a tissue embryo storage device. Background Technology

[0002] Tissue embryos generally refer to early embryonic structures composed of multiple cells during embryonic development. These cells, under specific environmental and conditions, separate, differentiate, and form tissues, eventually developing into a complete organism. In biological and medical research, tissue embryos are often used to study biological science issues such as embryonic development and cell differentiation. At the same time, in assisted reproductive technology, tissue embryos are also used for transplantation into the mother's uterus to achieve pregnancy and childbirth.

[0003] When storing and handling tissue embryos, it is necessary to strictly follow scientific and safety principles to ensure the survival, health and legality of the embryos. Under normal circumstances, tissue embryos are stored in storage tanks filled with liquid nitrogen to maintain the temperature at -196°.

[0004] However, when retrieving test tubes, users need to open the lid of the storage container, which increases the risk of viruses or bacteria entering the container. In addition, due to the extremely low temperature of liquid nitrogen, users are very likely to suffer frostbite if handled improperly. Therefore, a tissue embryo storage device is needed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a tissue embryo storage device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tissue embryo storage device, comprising:

[0007] A storage tank having an access port;

[0008] A placement rack is rotatably mounted inside a storage tank. The placement rack has multiple spaced-apart placement cylinders, and the diameter of the retrieval port is greater than or equal to the diameter of the placement cylinders.

[0009] A sealing assembly, the sealing assembly including a sealing piston, the sealing piston being inserted into the dispensing port;

[0010] A pipe jacking assembly is installed in the storage tank.

[0011] As a preferred embodiment, the sealing assembly further includes a rotating rod and a rotating ring. The sealing piston has a plurality of spaced-apart insertion posts, and the rotating ring has a plurality of spaced-apart insertion holes for the insertion posts to be inserted into. One end of the rotating rod is rotatably mounted on the upper end face of the storage tank, and the other end of the rotating rod is fixedly connected to the side wall of the rotating ring. The circumferential side wall of the sealing piston is in contact with the inner wall of the rotating ring.

[0012] As a preferred embodiment, the placement cylinder has a top pipe opening at one end away from the pick-up / placement port. The top pipe assembly includes a telescopic cylinder and a telescopic column. The telescopic column is installed inside the telescopic cylinder, and its upper and lower ends are fixed to the inner wall of the telescopic cylinder. The telescopic cylinder is inserted into the top pipe opening, and its lower end is installed on the bottom wall of the storage tank.

[0013] As a preferred embodiment, the jacking assembly further includes an air pump, and the lower end of the telescopic cylinder has an air inlet, with the air pump connected to the air inlet pipe.

[0014] As a preferred embodiment, the sealing piston further includes a plurality of spaced-apart sealing strips, which are in contact with the inner wall of the inlet / outlet.

[0015] As a preferred embodiment, the placement rack further includes a rotating rod and a rotating handle. The lower end of the rotating rod is rotatably mounted to the bottom wall of the storage tank, and the rotating handle is mounted to the upper end of the rotating rod, extending a certain distance outside the storage tank. The placement rack is fixedly installed with the rotating rod.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention features a placement rack rotatably mounted inside a storage tank. The rack includes placement tubes. Multiple test tubes containing tissue embryos are placed one by one into the placement tubes. The storage tank contains liquid nitrogen to keep the test tubes inside at a low temperature. At this time, the rotating ring rotates to a position concentric with the dispensing port, and the sealing piston is inserted into the dispensing port to ensure that the sealing strip fits the dispensing port. The insertion post is inserted into the insertion hole. This creates a closed, low-temperature environment inside the storage tank, and the dispensing port is aligned only with the opening of each placement tube, reducing the number of bacteria or viruses entering the storage tank through the dispensing port, thereby reducing the risk of tissue embryo infection.

[0018] This invention utilizes a jacking pipe assembly, comprising a telescopic cylinder, a telescopic column, and an air pump. The lower end of the telescopic cylinder has an air inlet, and the air pump is connected to the air inlet pipe. The placement cylinder has a jacking pipe opening at its end furthest from the pick-up / placement port. The telescopic column is installed inside the telescopic cylinder, with its upper and lower ends fixed to the inner wall of the telescopic cylinder. The telescopic cylinder is inserted into the jacking pipe opening, and its lower end is installed on the bottom wall of the storage tank. After startup, the air pump inflates the telescopic cylinder through the pipe and air inlet, stretching the telescopic cylinder and the telescopic column inside it. This causes the test tube in the placement cylinder to be lifted by the stretched telescopic cylinder and extended upwards from the pick-up / placement port. The user can then retrieve the lifted test tube without needing workers to enter the storage tank, reducing the risk of frostbite. Attached Figure Description

[0030] Sealing assembly 3, including sealing piston 31, which is inserted into the take-up and take-down port 11;

[0031] Pipe jacking assembly 4 is installed in storage tank 1;

[0032] The sealing assembly 3 also includes a rotating rod 32 and a rotating ring 33. The sealing piston 31 has a plurality of spaced insertion posts 311, and the rotating ring 33 has a plurality of spaced insertion holes 331 for the insertion posts 311 to be inserted into. One end of the rotating rod 32 is rotatably mounted on the upper end face of the storage tank 1, and the other end of the rotating rod 32 is fixedly connected to the side wall of the rotating ring 33. The circumferential side wall of the sealing piston 31 is in contact with the inner wall of the rotating ring 33.

[0033] The placement cylinder 21 has a top pipe opening 211 at one end away from the take-out port 11. The top pipe assembly 4 includes a telescopic cylinder 41 and a telescopic column 42. The telescopic column 42 is installed inside the telescopic cylinder 41, and the upper and lower ends of the telescopic column 42 are fixed to the inner wall of the telescopic cylinder 41. The telescopic cylinder 41 is inserted into the top pipe opening 211, and the lower end of the telescopic cylinder 41 is installed on the bottom wall of the storage tank 1.

[0034] The jacking pipe assembly 4 also includes an air pump 43, and the lower end of the telescopic cylinder 41 has an air inlet 411. The air pump 43 is connected to the air inlet 411 via a pipe.

[0035] The sealing piston 31 also includes a plurality of spaced sealing strips 312, which are in contact with the inner wall of the inlet / outlet 11.

[0036] The placement rack 2 also includes a rotating rod 22 and a rotating handle 23.

The placement rack 2 is fixedly installed with the rotating rod 22.

[0037] Working principle and usage process of this utility model:

[0038] In the initial state, multiple test tubes containing tissue embryos are placed one by one in the placement tube 21, and the storage tank 1 contains liquid nitrogen to keep the test tubes inside the storage tank 1 at a low temperature. At this time, the rotating ring 33 is rotated to a position concentric with the pick-up and drop-off port 11, and the sealing piston 31 is inserted into the pick-up and drop-off port 11 to ensure that the sealing strip 312 is in contact with the pick-up and drop-off port 11. The insertion post 311 is inserted into the insertion hole 331. In this way, the storage tank 1 is in a closed low-temperature environment, and the pick-up and drop-off port 11 is aligned only with the opening of each placement tube 21, reducing the number of bacteria or viruses entering the storage tank 1 from the pick-up and drop-off port 11.

[0039] When the user needs to retrieve the test tube from the placement cylinder 21, first turn the handle 23 until the opening of the placement cylinder 21 is aligned with the retrieval port 11; then, the user pulls the sealing piston 31 upwards in the direction away from the retrieval port 11 to ensure that the insertion post 311 is disengaged from the insertion hole 331 and the sealing strip 312 is disengaged from the retrieval port 11; then turn the sealing piston 31 again so that the insertion post 311 is placed on the upper surface of the rotating ring 33; finally, turn the rotating ring 33 until the rotating ring 33 is disengaged from the retrieval port 11.

[0040] After being started, the air pump 43 inflates the telescopic cylinder 41 through the pipe and the air inlet 411, which stretches the telescopic cylinder 41 and the telescopic column 42 placed inside the telescopic cylinder 41. This causes the test tube in the placement cylinder 21 to be lifted by the stretched telescopic cylinder 41 and extend upward from the pick-up and drop-off port 11. Then the user can pick up the lifted test tube without the need for workers to reach into the storage tank 1, reducing the risk of frostbite.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
