Technical Field

[0001] This utility model relates to the field of blood transfusion testing technology, specifically a blood transfusion testing extraction device. Background Technology

[0002] Blood transfusion is a treatment method that involves administering blood to a patient via intravenous infusion, and it is widely used in clinical practice. Currently, blood samples require low temperatures during transport to prevent damage and potential testing errors. Therefore, ice packs are used to lower the temperature and achieve the desired transport effect.

[0003] Existing blood transfusion testing extraction devices, due to the need to stably fix the test tubes, can make it inconvenient to remove the sample tubes, wasting the working time of medical staff, especially when their testing workload is heavy, thus delaying more valuable testing time. Utility Model Content

[0004] In view of the problems in the related technologies, this utility model proposes a blood transfusion test extraction device to overcome the above-mentioned technical problems existing in the existing related technologies.

[0005] Therefore, the specific technical solution adopted by this utility model is as follows:

[0006] A blood transfusion testing extraction device includes a box body and a placement box. The placement box is located inside the box body. Placement slots are arranged in an array inside the placement box. A top block is provided inside the placement slot. A second return spring is fixedly connected to the bottom of the top block. Clamping blocks are provided on both sides inside the placement slot. An extension plate is fixedly connected to one end of the clamping block.

[0007] A further improvement of this utility model is that: the top block and the placement groove are adapted to each other, the top block can slide inside the placement groove, and the bottom of the second reset spring is fixedly connected to the inner bottom of the placement groove.

[0008] Using the above technical solution, the second reset spring can drive the top block to perform a reset movement, causing the top block to push the sample tube placed inside the placement slot out, which can quickly push the sample tube out of the placement slot for medical staff to take out for testing, thus improving work efficiency.

[0009] A further improvement of this utility model is that the clamping block is semi-circular and symmetrically arranged on both sides inside the placement groove. One end of the clamping block is fixedly connected to a connecting block, and the clamping block is fixedly connected to the extension plate through the connecting block.

[0010] A further improvement of this utility model is that: the inner walls on both sides of the placement groove are provided with through grooves, the connecting block is slidably connected to the inside of the through groove, the inside of the through groove is provided with a slot, and the upper end of the slot is opened through the upper surface of the placement box.

[0011] Using the above technical solution, the connecting block in the solution can limit the clamping block, so that the clamping block can make linear sliding motion without any positional deviation.

[0012] A further improvement of this utility model is that: the extension plate and the slot are adapted to each other, the extension plate is slidably connected to the inside of the slot, the upper end of the extension plate is placed outside the upper surface of the box through the slot, and a third return spring is fixedly connected to one end of the extension plate, and the end of the third return spring away from the extension plate is fixedly connected to the inner side wall of the slot.

[0013] Using the above technical solution, the extension plate can be pushed to drive the connecting block to move the clamping block, thereby loosening the clamping block's grip on the sample tube, making it easier to remove the sample tube from the placement slot. The third reset spring can drive the extension plate to move the clamping block to reset, so that the clamping block clamps and fixes the sample tube placed in the placement slot, providing good stability.

[0014] A further improvement of this utility model is that: the bottom edge of the top block is provided with a first inclined surface, and the end of the clamping block away from the connecting block is provided with a second inclined surface, and the first inclined surface and the second inclined surface are in contact with each other.

[0015] Using the above technical solution, the first and second inclined surfaces are used to rub against each other. When the sample tube is pressed into the placement groove, it will contact the top block. Then, it can continue to be pressed down. During the pressing process, the first and second inclined surfaces will rub against each other, causing the clamping block to move to both sides under the thrust of friction. This causes the top block to be pressed down to the bottom of the clamping block, which facilitates the clamping block to clamp and fix the sample tube, and allows the sample tube to be quickly removed afterward.

[0016] A further improvement of this utility model is that: the inside of the box body is provided with a movable groove, the placement box is movably connected to the inside of the movable groove, the inside of the movable groove is provided with a top plate, the top plate is located at the bottom of the placement box, and a first return spring is fixedly connected to the bottom of the top plate, the first return spring being fixedly connected to the bottom of the movable groove.

[0017] Using the above technical solution, the first reset spring can drive the top plate to perform a reset movement, thereby driving the placement box to perform a reset movement, so that the placement box can move upward, further facilitating the staff to take out the sampling test tubes and providing convenience.

[0018] A further improvement of this utility model is that: the two ends of the upper surface of the box body are provided with limiting grooves, the box cover is provided at the upper end of the box body, the two ends of the bottom of the box cover are fixedly connected with limiting rails, and the box cover is slidably connected to the upper end of the box body through the limiting rails and limiting grooves.

[0019] The beneficial effects of this utility model are as follows:

[0020] By pushing the extension plate to move the clamping block, the clamping block is released from its grip on the sample collection tube. At this time, the second reset spring can drive the top block to perform a reset movement, causing the top block to eject the sample collection tube placed inside the placement slot. This allows the sample collection tube to be quickly ejected from the placement slot for easy removal by medical staff for testing, thus improving work efficiency.

[0021] The first reset spring can drive the top plate to reset, which in turn drives the placement box to reset, allowing the placement box to move upward, further facilitating the removal of the sampling tubes by staff and providing convenience. Attached Figure Description

The clamping block 307 is semi-circular and symmetrically arranged on both sides inside the placement groove 301. One end of the clamping block 307 is fixedly connected to a connecting block. The clamping block 307 is fixedly connected to the extension plate 309 through the connecting block. Through grooves 305 are opened on both sides of the inner wall of the placement groove 301. The connecting block is slidably connected to the inside of the through groove 305. The inside of the through groove 305 is provided with a slot 306. The upper end of the slot 306 extends through the upper surface of the placement box 3. The extension plate 309 is adapted to the slot 306. The extension plate 309 is slidably connected to the inside of the slot 306. The upper end of the extension plate 309 is placed outside the upper surface of the placement box 3 through the slot 306. A third return spring 3010 is fixedly connected to one end of the extension plate 309. The end of the third return spring 3010 away from the extension plate 309 is fixedly connected to the inner side wall of the slot 306.

[0036] In this embodiment, the second reset spring 304 can drive the top block 302 to perform a reset movement, causing the top block 302 to eject the sample tube placed inside the placement slot 301. This allows the sample tube to be quickly ejected from the placement slot 301 for easy removal by medical personnel for testing, improving work efficiency. The connecting block can limit the clamping block 307, allowing it to slide linearly without positional deviation. The extension plate 309 can be pushed, causing the connecting block to move the clamping block 307, thereby releasing the clamping block 307 from the sample tube and facilitating its removal from the placement slot 301. The third reset spring 3010 can drive the extension plate 309 to perform a reset movement, causing the clamping block 307 to clamp and fix the sample tube placed inside the placement slot 301, providing good stability.

[0037] Example 3;

[0038] like Figure 1-4As shown, in the blood transfusion testing and extraction device according to an embodiment of the present invention, the bottom edge of the top block 302 is provided with a first inclined surface 303, and the end of the clamping block 307 away from the connecting block is provided with a second inclined surface 308. The first inclined surface 303 and the second inclined surface 308 are in contact with each other. The inside of the box body 1 is provided with a movable groove 101. The placement box 3 is movably connected to the inside of the movable groove 101. The inside of the movable groove 101 is provided with a top plate 102. The top plate 102 is located at the bottom of the placement box 3. The bottom of the top plate 102 is fixedly connected with a first return spring 103. The first return spring 103 is fixedly connected to the bottom of the movable groove 101. Limiting grooves 104 are provided at both ends of the upper surface of the box body 1.
