Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a blood sample storage device for liquid biopsy. Background Technology

[0002] Blood sample storage devices generally refer to equipment used to store and protect blood samples to maintain their integrity and viability for subsequent analysis or processing. These devices can take many forms, depending on the application and requirements. For example, for long-term preservation of blood samples, especially when maintaining biological activity is necessary, specialized refrigerators (4°C) or freezers (-20°C, -80°C, or even stored in liquid nitrogen tanks at -196°C) are used to slow down sample degradation.

[0003] A search of Chinese Patent Publication No. CN221419086U reveals a blood sample storage device, comprising a warming cabinet and several storage plates. The warming cabinet has a door, and the interior of the cabinet contains several partitions, with the storage plates slidably connected above the partitions. Each storage plate has several storage holes, and each storage hole has a limiting part above it, with a through hole inside the limiting part communicating with the storage hole. Insulation bags are provided on the inner side of the top of the warming cabinet and the bottom of the partitions, with protective sections between the insulation bags and the bottom of the test tubes. This addresses the problems of blood sample tubes falling and cumbersome low-temperature storage operations in existing blood sample storage devices.

[0004] However, the aforementioned patent has certain limitations in its use. First, users still need to manually open the storage box door when retrieving test tubes. This operation inevitably leads to a significant loss of cold air inside the storage device, affecting overall temperature stability and consequently adversely impacting other blood samples that have not yet been retrieved. This cold air loss problem is particularly pronounced during frequent sampling or in high ambient temperatures, increasing energy consumption and reducing preservation efficiency. Furthermore, when retrieving test tubes located deep within or at the back of the storage device, users often need to reach into the box, which is not only inconvenient and time-consuming but also carries the risk of accidentally touching other test tubes due to obstructed vision, leading to sample confusion or contamination. Simultaneously, prolonged opening of the box door extends the time required for the system to return to a low-temperature state, further affecting the device's operating efficiency and sample preservation quality. Utility Model Content

[0005] The purpose of this invention is to provide a blood sample storage device for liquid biopsy, addressing the problems in the prior art mentioned above, where users need to manually open the cabinet door to retrieve test tubes, resulting in significant loss of cold air, affecting temperature stability, increasing energy consumption, and reducing storage efficiency. For test tubes located deep within the sample container, reaching in is inconvenient and increases the risk of accidentally touching other samples, leading to confusion or contamination.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a blood sample storage device for liquid biopsy, comprising a storage box, the surface of which is provided with a rotating assembly, the rotating assembly comprising a fixed box and several movable plates, sprockets being rotatably connected to the left and right sides of the top of the movable plates, chains being drivenly connected to the surfaces of the several sprockets, several storage sleeves being connected to the surfaces of the chains, and several rubber sleeves being fixedly connected to the inner cavity of the storage sleeves.

[0007] Furthermore, a motor is fixedly connected to the inner cavity of the fixed box, and rotating rods are rotatably connected to both sides of the inner cavity of the storage box.

[0008] Furthermore, the output shaft of the motor is fixedly connected to one end of the rotating rod, and a disc is fixedly connected to the opposite end of each of the two rotating rods.

[0009] Furthermore, the surface of the disc is connected to the surface of the movable plate, and a groove is provided on the top of the sprocket.

[0010] Furthermore, a running rod is provided through the top of the inner cavity of the storage box, and a handwheel is fixedly connected to the top of the running rod.

[0011] Furthermore, a protruding rod is fixedly connected to the bottom end of the operating rod, and the protruding rod and the groove cooperate with each other.

[0012] Furthermore, the top of the storage box has a placement cavity, and a cover plate is slidably connected to the inner side of the placement cavity.

[0013] Furthermore, a cooling device is installed on the left side of the storage box, and the cooling device works in conjunction with the rotating assembly.

[0014] The technical solution provided by this utility model has the following advantages compared with the known prior art: I. This utility model, through its rotating component, enables the storage sleeve and the test tubes within it to rotate, allowing for flexible adjustment of the test tube positions as needed, thus significantly improving the convenience for users during sampling. During test tube retrieval, the user can precisely locate the target test tube using the rotating component and retrieve them one by one, effectively avoiding the problem of significant cold air loss caused by frequent opening of the cabinet door or prolonged exposure to the internal environment. II. Furthermore, the rotating component of this utility model allows for the adjustment of test tubes located deep within or at the rear of the storage device to a more easily accessible position, eliminating the need for the user to reach deep into the cabinet to search. This not only reduces operational difficulty and labor intensity but also minimizes the risk of confusion or contamination from accidental contact with other samples, making it easier to use.

[0018] The present invention will be further described below with reference to the embodiments.

[0019] Example: A blood sample storage device for liquid biopsy, such as Figures 1-8As shown, the device includes a storage box 1. The surface of the storage box 1 is provided with a rotating assembly 3. The rotating assembly 3 includes a fixed box 31 and several movable plates 35. The surface of the fixed box 31 is fixedly connected to the left side of the storage box 1. The top left and right sides of the movable plates 35 are rotatably connected to sprockets 36. The surfaces of the several sprockets 36 are connected to chains 37. The chains 37 and sprockets 36 are treated to prevent freezing and low temperature. The surface of the chains 37 is connected to several storage sleeves 38. The storage sleeves 38 are used to store blood sample tubes, and the diameter of the storage sleeves 38 can be increased or decreased according to actual operation. The inner cavity of the storage sleeves 38 is fixedly connected to several rubber rings 39.

[0020] like Figures 2-8 As shown, a motor 32 is fixedly connected to the inner cavity of the fixed box 31. Rotating rods 33 are rotatably connected to both sides of the inner cavity of the storage box 1. The output shaft of the motor 32 is fixedly connected to one end of the rotating rod 33. A disc 34 is fixedly connected to the opposite end of each of the two rotating rods 33. The surface of the disc 34 is connected to the surface of the moving plate 35. A weight is installed at the bottom of the moving plate 35 to facilitate the rotation of the disc 34 and drive the moving plate 35 to rotate in a circular motion. A groove 310 is provided on the top of the sprocket 36. A running rod 311 is provided through the top of the inner cavity of the storage box 1, and a handwheel is fixedly connected to the top of the running rod 311. A through cavity adapted to the running rod 311 is provided on the top of the storage box 1. A sealing cover is installed on the top of the storage box 1 to facilitate the user to seal the running rod 311 when it is removed, preventing the leakage of cooling gas inside the storage box 1. The bottom end of storage box 1 is fixedly connected to a protruding rod 312, which cooperates with the groove 310. Several protrusions are fixedly connected to the surface of the protruding rod 312, and the inner cavity of the groove 310 is provided with several recessed grooves that match the protrusions. The top of storage box 1 is made of transparent material to facilitate the user's observation of the inside of storage box 1 and easy removal of test tubes. The front side of storage box 1 is hinged with a door to facilitate the user's maintenance of the internal parts of storage box 1. The top of storage box 1 is provided with a placement cavity 313, and a cover plate 314 is slidably connected to the inner side of placement cavity 313. The cover plate 314 is made of transparent material to facilitate the user's removal of test tubes through placement cavity 313. A cooling device 2 is installed on the left side of storage box 1, and the cooling device 2 cooperates with the rotating component 3. The cooling device 2 can preferably be a device that can generate cold air, such as a cooler, to facilitate the low-temperature preservation of blood samples.

[0021] Specifically, when the user needs to remove the blood test tube, the motor 32 is activated. The motor 32 drives the rotating rod 33 to rotate, which in turn drives the disc 34 to rotate. The disc 34 then drives the moving plate 35 to rotate, which in turn drives the corresponding storage sleeve 38 to rotate, moving the moving plate 35 to the top position inside the storage box 1. At this time, the user manually inserts the running rod 311 and the protruding rod 312 into the sprocket 36. Through the cooperation of the protruding rod 312 and the groove 310, the sprocket 36 can be rotated. When the sprocket 36 rotates, it drives the chain 37 to move, which in turn drives the storage sleeve 38 to rotate. The test tube is fixed in the storage sleeve 38 by the rubber collar 39, achieving a limited placement. At this time, the user can confirm the position of the test tube to be removed by observing the rotation of the storage sleeve 38. Then, the user manually opens the cover plate 314 and removes the corresponding test tube, effectively reducing the loss of cooling gas inside the storage box 1 and improving the convenience and stability of operation. The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
