Description

Technical Field

[0001] This utility model relates to the field of blood storage technology, specifically to a blood collection and storage device. Background Technology

[0002] In the clinical testing and diagnosis of hematological diseases, the standardized collection and reliable storage of patient blood samples are the primary steps to ensure the accuracy of test results. Currently, the routine blood sampling procedure mainly relies on blood drawing devices (such as syringes or vacuum blood collection tube systems) to draw blood into dedicated blood sample containers (such as vacuum blood collection tubes or blood sample bottles). The collected blood sample containers are then transferred to constant temperature or refrigerated storage devices for static preservation until subsequent laboratory testing and analysis.

[0003] However, the static storage method commonly used in the existing technology has significant technical defects: when blood samples are stored statically in the container for a long time, the various formed elements contained in them are easily separated due to the influence of gravity, and a clear interface is formed between the plasma and the cell layer; at the same time, some soluble proteins or analytes in the plasma may also produce uneven local concentrations or precipitation due to static storage, which greatly affects the accuracy of clinical diagnosis. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a blood collection and storage device that can dynamically store blood sample bottles and avoid the sedimentation and stratification of blood samples.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a blood collection and storage device, including a storage box, a box cover fixedly connected to the upper end of the storage box, a transmission roller rotatably connected to both ends inside the storage box, a transmission belt provided between the two sides of the transmission roller, a motor for driving the rotation of one side of the transmission roller fixedly connected to the upper end of the box cover, connecting blocks evenly arranged fixedly connected to the outer wall of the transmission belt, a fixed outer cylinder fixedly connected to one end of each connecting block, a fixed inner cylinder rotatably connected to each fixed outer cylinder, a collection bottle fixing mechanism provided inside the fixed inner cylinder, a transmission gear ring fixedly sleeved on the bottom surface of the fixed inner cylinder, an inner gear ring corresponding to the outer contour of the transmission belt fixedly connected inside the storage box, a pick-and-place port provided at one end of the box cover, a sealing cap installed inside the pick-and-place port, and an ejection mechanism provided inside the storage box directly below the pick-and-place port.

[0006] As an improvement, the collection bottle fixing mechanism includes multiple fixing slots arranged in a circular array along the inner wall of the fixing inner cylinder, a fixing block is slidably inserted into the fixing slot, a fixing spring for driving the fixing block to cooperate is fixedly connected in the fixing slot, and a fixing clamp is fixedly connected to one end of the fixing block extending outside the fixing slot.

[0007] As an improvement, a vertically arranged support plate is fixedly connected to the bottom surface of the fixed clamping plate.

[0008] As an improvement, a protective cover box that cooperates with the motor is fixedly connected to the box cover.

[0009] As an improvement, the ejection mechanism includes an electric push rod fixedly connected to the bottom surface of the storage box, with a top block fixedly connected to the upper end of the electric push rod.

[0010] As an improvement, the internal gear ring is in the shape of a monolithic circle.

[0011] A support platform is fixedly connected inside the storage box between the two transmission rollers, and the transmission belt is also connected to the outer walls of the support platform on both sides.

[0012] The advantages of this invention compared to existing technologies are as follows: By setting up a dynamic rotating storage mechanism consisting of a transmission belt, connecting block, fixed outer cylinder, fixed inner cylinder, transmission gear ring, and inner gear ring, continuous passive rotation of the blood sample bottle is achieved during the storage process. This rotational motion effectively breaks the sedimentation equilibrium caused by gravity during static storage of blood samples, keeping the blood components in the blood sample bottle in a highly uniform mixed state. This significantly overcomes the problems of uneven composition, interface formation, and precipitation caused by sedimentation stratification in existing technologies, fundamentally ensuring the accuracy and reliability of subsequent clinical test results.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] like Figures 1 to 5 As shown, a blood collection and storage device includes a storage box 1, a lid 2 fixedly connected to the upper end of the storage box 1, two rotatably connected transmission rollers 3 inside the storage box 1, and a transmission belt 6 between the two sides of the transmission rollers 3. A motor 4 for driving one side of the transmission roller 3 is fixedly connected to the upper end of the lid 2. A support platform 17 is fixedly connected inside the storage box 1 between the two sides of the transmission rollers 3. The transmission belt 6 is also connected to the outer walls of both sides of the support platform 17. A protective cover box 5 that cooperates with the motor 4 is fixedly connected to the lid 2. Evenly arranged connecting wires are fixedly connected to the outer wall of the transmission belt. Each connecting block has a fixed outer cylinder 7 fixedly connected to one end, and a fixed inner cylinder 8 rotatably connected inside the fixed outer cylinder 7. The fixed inner cylinder 8 is provided with a collection bottle fixing mechanism, which includes multiple fixing slots arranged in a circular array on the inner wall of the fixed inner cylinder 8. A fixing block 12 is slidably inserted into the fixing slot, and a fixing spring 13 is fixedly connected inside the fixing slot to drive the fixing block 12 to cooperate. A fixing clamp 11 is fixedly connected to one end of the fixing block 12 extending outside the fixing slot, and a vertically arranged support plate 18 is fixedly connected to the bottom surface of the fixing clamp 11.

[0021] A transmission gear ring 9 is fixedly sleeved on the bottom surface of the fixed inner cylinder 8. An inner gear ring 10 corresponding to the outer contour of the transmission belt 6 is fixedly connected inside the storage box 1. The inner gear ring 10 is circumferential. One end of the box cover 2 is provided with a pick-up and put-out port 15. A sealing cover 16 is installed inside the pick-up and put-out port 15. An ejection mechanism is provided inside the storage box 1 directly below the pick-up and put-out port 15. The ejection mechanism includes an electric push rod 14 fixedly connected to the bottom surface of the storage box 1. A top block is fixedly connected to the upper end of the electric push rod 14.

[0022] In practical use, the sealing cover 16 is opened, and the collected blood sample bottle is inserted vertically downward into the fixed inner cylinder 8 located directly below the take-up and put-out port 15 on the cover 2. During the insertion of the blood sample bottle, the outer wall of the bottle body contacts and pushes open the fixed clamping plate 11, compressing the fixed spring 13. Under the restoring force of the fixed spring 13, the fixed clamping plate 11 tightly clamps the blood sample bottle body, completing the automatic fixation. At the same time, the support plate 18 supports the bottom surface of the sampling bottle. At this time, the blood sample bottle is constrained in the fixed outer cylinder 7 along with the fixed inner cylinder 8.

[0023] The sealing cap 16 is closed to maintain the storage environment. The motor 4 is started, driving the connected transmission roller 3 to rotate. This, in turn, drives the transmission belt 6 to circulate along the path formed by the transmission rollers 3 at both ends inside the storage box 1. When the transmission belt 6 moves, it drives the fixed outer cylinder 7 and the fixed inner cylinder 8, along with the fixed blood sample bottles, to move synchronously through the connecting block fixed to its outer wall. When the fixed inner cylinder 8 moves with the transmission belt 6, the transmission gear ring 9 fixed at its bottom meshes with the internal gear ring 10 fixed in the storage box 1, which is shaped to match. The transmission gear ring 9 rolls along the internal gear ring 10, causing the fixed inner cylinder 8 to rotate within the fixed outer cylinder 7. The fixed inner cylinder 8 drives the fixed blood sample bottles inside to rotate continuously and passively. As the blood sample bottles circulate with the belt, they rotate continuously, effectively preventing blood components from settling and separating.

[0024] When a specific blood sample bottle needs to be removed, the motor 4 is activated, moving the fixed inner cylinder 8 containing the target blood sample bottle to a position directly below the retrieval port 15. The motor 4 is then stopped. The electric push rod 14 is then extended, pushing the top block at its tip upwards. The top block acts on the bottom of the blood sample bottle, overcoming the clamping force of the fixed clamping plate 11, and smoothly pushes the blood sample bottle upwards out of the fixed inner cylinder 8, partially or completely exposing it to the retrieval port 15 for easy removal by the operator. After removal, the electric push rod 14 retracts.
