[0002] A peripheral whole blood sample preservation device is a device used to preserve whole blood samples collected from the extremities of the human body (such as fingertips, earlobes, or heels).

[0003] Currently, traditional blood sample preservation devices typically place blood sample tubes on multi-well tube holders for preservation. However, because multi-well tube holders have a simple structure, they do not provide reinforcement and protection for blood sample tubes. They are prone to being jostled during transport, causing the blood sample tubes to bounce up and down, which can easily damage the blood sample tubes. Utility Model Content

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing description of the drawings are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings are used to distinguish different objects, not to describe a particular order; the terms "inner," "outer," "left," and "right" indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0021] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] This utility model provides a blood sample preservation device, such as... Figure 1-4As shown, the blood sample preservation device includes: a box 1 for preserving blood samples, and a shelf 4 for placing test tubes inside the box 1; a support net 2 fixedly installed inside the box 1 for storing the shelf 4; a limiting rod 3 fixedly installed on the support net 2 and slidably connected to the shelf 4, the limiting rod 3 being used to prevent the shelf 4 from moving left or right; a pressure plate 5 inside the box 1 for preventing the test tubes from jumping up and down, the bottom of the pressure plate 5 being fixedly installed with a silicone pad 6, and the silicone pad 6 being in close contact with the cap of the test tube; and a set of height adjustment mechanisms all provided on the box 1 for adjusting the height of the pressure plate 5.

[0023] In this embodiment, when in use, the blood sample tube is first placed on the placement rack 4, and then the entire placement rack 4 is placed on the support net 2 inside the box 1. The support net 2 provides a stable support platform for the placement rack 4. At the same time, the limiting rod 3 is slidably connected to the placement rack 4. This design effectively prevents the placement rack 4 from moving left and right inside the box 1, increasing stability.

[0024] To prevent blood sample tubes from bouncing up and down during transport, pressure plate 5 and silicone pad 6 are pressed against the top of the tube, confining it between pressure plate 5 and the rack 4 to ensure it does not bounce. The softness and elasticity of silicone pad 6 allow it to make close contact with the tube cap, thus securing the tube. The combination of limiting rod 3 and support net 2 effectively prevents the rack 4 and the tubes on it from moving left and right during transport, increasing overall stability. At the same time, the design of pressure plate 5 and silicone pad 6 further prevents the tubes from bouncing up and down, thus avoiding the risk of damage to the tubes due to bumps.

[0025] In a further preferred embodiment of this utility model, the height adjustment mechanism includes: a connecting box 7 fixedly installed on one side of the housing 1; a one-way screw 8 rotatably installed in the connecting box 7 for adjusting the height of the pressure plate 5; and a slider 9 threadedly sleeved on the one-way screw 8, one side of the slider 9 being fixedly connected to the pressure plate 5; a first handle 10 fixedly installed at the top of the one-way screw 8 for driving the one-way screw 8 to rotate; and a sprocket 11 fixedly sleeved on the one-way screw 8, with a chain 12 sleeved on the sprocket 11.

[0026] In this embodiment, since a set of height adjustment mechanisms is provided on the housing 1, the height of the pressure plate 5 is adjusted synchronously by the set of height adjustment mechanisms, and a set of one-way screws 8 are connected by sprocket 11 and chain 12, so that the set of one-way screws 8 can rotate synchronously.

[0027] When it is necessary to remove the placement rack 4, first turn the first handle 10 to drive the one-way screw 8 to rotate. While the one-way screw 8 is rotating, through the chain drive of the sprocket 11 and the chain 12, the other one-way screw 8 rotates synchronously, causing the one-way screw 8 to drive the slider 9 to slide the pressure plate 5 upward, so that the silicone pad 6 slides upward away from the test tube. Then the box can be opened and the placement rack 4 can be removed from the support net 2. By precisely adjusting the height of the pressure plate 5, it can be ensured that the test tube will not jump up and down or move left and right due to bumps during storage and transportation, thereby enhancing the overall stability.

[0028] In a further preferred embodiment of the present invention, the bottom of the box 1 is provided with a refrigeration mechanism for refrigerating and preserving blood samples. The refrigeration mechanism includes: a water tank 13 fixedly installed at the bottom of the box 1; a cooling plate 14 installed on one side of the water tank 13 for cooling water; fins 15 respectively installed on both sides of the cooling plate 14; a controller 16 installed on one side of the water tank 13 for regulating the cooling state of the cooling plate 14; and openings 17 respectively opened on the water tank 13 and the box 1, with a group of openings 17 connected together.

[0029] In this embodiment, when the room temperature is high in summer, the user can activate the refrigeration mechanism to cool the water in the water tank 13 using the cooling element 14. As the water temperature drops, the cold air rises into the cabinet 1 through the inlet 17, effectively reducing the temperature inside the cabinet 1 and providing an ideal refrigeration environment for the preservation of blood samples. Through the design of the refrigeration mechanism, the refrigeration preservation of blood samples is achieved. This function is particularly important in high-temperature environments such as summer, as it can effectively extend the preservation time of blood samples and improve the preservation quality. The introduction of the controller 16 allows the user to accurately set the refrigeration temperature and automatically adjust the working state of the cooling element 14 to maintain a constant temperature, which helps to ensure that blood samples are preserved under suitable refrigeration conditions and avoids sample damage caused by excessively high or low temperatures.

[0030] In a further preferred embodiment of the present invention, an insulation layer 18 for keeping cold water warm is installed inside the water tank 13, a mesh box 19 is fixedly installed on one side of the water tank 13, the mesh box 19 covers the fins 15, and a cooling fan 20 for dissipating heat from the fins 15 is fixedly installed inside the mesh box 19.

[0031] In this embodiment, when the refrigeration mechanism is working, the insulation layer 18 effectively prevents external heat from entering the water tank 13, thereby maintaining a constant water temperature. Additionally, when the cooling element 14 is working, the fins 15 absorb a large amount of heat, causing the temperature to rise. The cooling fan 20 generates airflow to remove the heat from the fins 15, thus keeping the temperature of the fins 15 within a safe range and ensuring the continuous and efficient operation of the cooling element 14. The insulation layer 18 not only improves refrigeration efficiency but also extends the refrigeration time. After the refrigeration mechanism stops working, the insulation layer 18 slows down the rate of water temperature rise, thereby extending the storage time of blood samples under suitable refrigeration conditions.

[0032] In a further preferred embodiment of this utility model, a sealing mechanism for sealing the opening 17 is provided inside the housing 1. The sealing mechanism includes: a bidirectional screw 21 rotatably installed inside the housing 1, the bidirectional screw 21 being located below the support mesh 2; a connecting block 22 threaded onto the bidirectional screw 21; a sealing plate 23 fixedly installed at the bottom of the connecting block 22 for sealing the opening 17, the bottom of the sealing plate 23 being in sliding contact with the bottom of the inner wall of the housing 1; and a second handle 24 fixedly installed at one end of the bidirectional screw 21 for driving the bidirectional screw 21 to rotate.

[0033] In this embodiment, when the container 1 needs to be transferred, the opening 17 needs to be sealed to prevent water from the water tank 13 from spilling into the container 1. When the opening 17 needs to be sealed, the user can drive the bidirectional screw 21 to rotate by rotating the second handle 24. As the bidirectional screw 21 rotates, the two connecting blocks 22 will move towards the opening 17 at the same time, causing the sealing plate 23 to move to one side and fit tightly around the opening 17 to achieve a sealing effect. Through the setting of the sealing mechanism, it can be ensured that when the container 1 is transferred, the water in the water tank 13 will not flow back into the container 1, and the sealing effect is good.

[0034] In a further preferred embodiment of the present invention, a fan blade 25 for driving water flow is rotatably installed on one side of the inner wall of the water tank 13, and a motor 26 is fixedly installed on one side of the water tank 13, with the output shaft of the motor 26 fixedly connected to the rotating shaft of the fan blade 25.

[0035] In this embodiment, when the motor 26 drives the fan blade 25 to rotate, a driving force is generated, causing the water in the water tank 13 to begin circulating. This circulation not only helps to transfer the cold air generated by the cooling chip 14 to the entire water tank 13 more quickly, but also improves the cooling efficiency of the water, making the water temperature more uniform. The combination of the fan blade 25 and the motor 26 enables the water in the water tank 13 to circulate, which helps to transfer the cold air generated by the cooling chip 14 to the entire water tank 13 more quickly. At the same time, the circulation of water can also improve the cooling efficiency and make the water temperature more uniform, providing a more stable environment for the cold storage of blood samples.

[0036] In a further preferred embodiment of the present invention, a door is hinged to one side of the box body 1, and observation windows 27 are installed on both the door and the water tank 13. The two observation windows 27 are used to observe the water level of the water tank 13 and the location of the sealing plate 23, respectively.

[0037] In this embodiment, the observation window 27 on the cabinet door allows the user to observe the inside of the cabinet 1 without opening the cabinet door, especially the position of the sealing plate 23. This helps the user to quickly determine whether the opening 17 has been effectively sealed, thereby ensuring the stability of the refrigeration environment. The observation window 27 on the water tank 13 is used to observe the water level in the water tank 13 to ensure that the water volume is appropriate to maintain the cooling effect.

[0038] In summary, compared with related technologies, this device, through effective fixation and protection measures, can ensure the safety and integrity of blood samples during preservation and transportation.

[0039] It should be understood, in the several embodiments provided in this application, that the disclosed apparatus may be implemented in other ways.
