Description

Technical Field

[0001] This utility model relates to the field of blood collection tube placement frame technology, and in particular to a blood collection tube placement frame. Background Technology

[0002] In the field of medical testing, blood collection tubes are essential tools for collecting and preserving patient blood samples, while blood collection tube racks are used to store and manage these tubes in an orderly manner. Currently, commonly available blood collection tube racks have many shortcomings, causing inconvenience to medical staff and affecting the efficiency and safety of blood collection tube management.

[0003] Most existing blood collection tube holders are fixed structures, unable to be flexibly adjusted according to the actual number of blood collection tubes. When collecting a small number of blood collection tubes, the holder still occupies a large amount of space, resulting in wasted space; while when collecting a large number of blood collection tubes, the fixed structure of the holder cannot provide sufficient placement space, limiting its application scenarios. To solve the above technical problems, existing technologies have also designed foldable blood collection tube holders. Although some foldable blood collection tube holders have solved the space occupation problem to a certain extent, they lack effective support and limiting devices during folding and unfolding. For example, double-layer blood collection tube holders are not easy to keep the two holders stably on the same horizontal plane after unfolding. When moving and transferring the holders, they are prone to shaking and instability. That is, when lifting one holder, the other holder may fold down, causing the blood collection tube to fall, affecting the safety of blood collection tube placement and the accuracy of medical staff operation.

[0004] Therefore, we propose a blood collection tube placement stand to solve the above-mentioned problems. Utility Model Content

[0005] This utility model provides a blood collection tube placement frame to solve the aforementioned technical problems.

[0006] The present invention adopts the following technical solution: it includes a first frame and a second frame connected by a folding structure, and a placement frame consisting of placement holes evenly opened on the first frame and the second frame. It also includes a limiting member installed between the first frame and the second frame. In the initial state, the second frame is located at the bottom of the first frame. The limiting member is used to support and limit the second frame when the second frame is folded to the same horizontal plane as the first frame. The limiting member includes a central support member fixedly assembled at the bottom of the first frame and serving as a rotation base point, a limiting blocking member rotatably connected to the central support member, a connecting positioning member fixed at the bottom of the second frame, and a snap-fit ​​positioning structure opened at the end of the limiting blocking member and matching the connecting positioning member.

[0007] Furthermore, both the first frame and the second frame are double-layer frames. The placement holes include a first placement hole opened on one side of the double-layer frame and a second placement hole opened on the other side of the double-layer frame and corresponding to the first placement hole. A positioning cylinder is detachably connected to the bottom of the second placement hole.

[0008] Furthermore, positioning rings are installed inside the positioning cylinder and at the inner edge of the second placement hole, and an anti-slip pad is also provided inside the positioning cylinder. The two positioning rings are arranged along the thickness direction of the double-layer frame.

[0009] Furthermore, a rotatable digital disk is installed on the double-layer frame at the location corresponding to each column of first placement holes. The digital disk is marked with different numbers to mark the patient's bed number.

[0010] Furthermore, the central support component is a damped rotating shaft, which can provide a certain resistance when the limiting and blocking component rotates, preventing the limiting and blocking component from rotating arbitrarily due to slight external forces, and ensuring that the limiting and blocking component maintains a stable position when not operated manually.

[0011] Furthermore, the limiting and blocking member is a long plate-shaped body, the length of which is less than that of the placement frame.

[0012] Furthermore, the connecting positioning component is a cylindrical rod, and the engaging positioning structure is a U-shaped slot opened on the limiting blocking component away from the central support component, the opening size of which is adapted to the diameter of the connecting positioning component.

[0013] The above-mentioned technical solutions adopted in the embodiments of this utility model can achieve the following beneficial effects: This utility model's blood collection tube placement rack adopts a folding structure. The first and second frames can be flexibly folded and unfolded according to the number of blood collection tubes. In the initial state, the second frame is located at the bottom of the first frame, saving space. When more blood collection tubes need to be placed, the second frame is folded up to be on the same horizontal plane as the first frame, and supported and limited by limiting members. This ensures that both frames are on the same horizontal plane during use, preventing the blood collection tubes from falling off due to the folding of the frames when the blood collection rack is moved.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] The existing blood collection tube placement frame of this utility model mainly includes a first frame 1 and a second frame 2, which are connected by a folding structure. Placement holes are evenly opened on the first frame 1 and the second frame 2 to form the main body of the placement frame 4. This folding structure is existing technology and may include a first rotating shaft 16, a second rotating shaft 17, and a rotating arm 18. The first rotating shaft 16 is rotatably connected to a connecting rod installed on the side wall of the first frame 1, and the second rotating shaft 17 is rotatably connected to a connecting rod installed on the side wall of the second frame 2. A rotating arm 18 is also provided between the first rotating shaft 16 and the second rotating shaft 17. The two ends of the rotating arm 18 are rotatably connected to the first rotating shaft 16 and the second rotating shaft 17, respectively. The length of the rotating arm 18 in the folded state is the distance between the first frame 1 and the second frame 2, thereby realizing the folding and unfolding of the first frame 1 and the second frame 2. The above is an introduction to the existing blood collection tube placement frame.

[0018] As can be seen from the above, the existing blood collection tube placement racks have the following defects when in use. Although some foldable blood collection tube placement racks have solved the space occupation problem to a certain extent, they lack effective support and limiting devices during folding and unfolding. For example, double-layer blood collection tube placement racks are not easy to keep the two placement racks 4 stably on the same horizontal plane after unfolding. When moving and transferring placement racks 4, they are prone to shaking and instability. That is, when one placement rack 4 is lifted, the other placement rack 4 may fold down, causing the blood collection tube to fall, affecting the safety of blood collection tube placement and the accuracy of medical staff operation. Based on the above problems, the present invention adopts the following improvement method to solve them.

[0019] like Figure 1-6 As shown, a blood collection tube placement frame, based on existing technology, adds a limiting member 5 between the first frame 1 and the second frame 2. In the initial state, the second frame 2 is located at the bottom of the first frame 1. The limiting member 5 is used to support and limit the second frame 2 when it is folded to the same horizontal plane as the first frame 1. Specifically, the limiting member 5 includes a central support member 6 fixedly mounted at the bottom of the first frame and serving as a rotation base point, a limiting blocking member 7 rotatably connected to the central support member, a connecting positioning member 8 fixed to the bottom of the second frame, and a locking positioning structure opened at the end of the limiting blocking member 7 and matching the connecting positioning member 8. The central support member 6 is damped (e.g., friction damping, produced by the extrusion of gaskets, friction plates, or metal). The rotating shaft 3 (generating friction) provides resistance when the limiting blocking member 7 rotates, preventing it from rotating arbitrarily due to slight external forces and ensuring its stable position during non-human operation. Simultaneously, the bottom support of the rotating shaft 3 is larger than the diameter of its upper part, preventing the limiting blocking member 7 from slipping off the bottom of the rotating shaft 3. The limiting blocking member 7 is a metal plate of a certain thickness with a rust-proof surface to extend its service life. The connecting positioning member 8 is a cylindrical metal rod with a smooth surface, facilitating its engagement with the locking and positioning structure. The locking and positioning structure is a U-shaped groove 15 with an opening size adapted to the diameter of the connecting positioning member 8. To enhance the tightness of the engagement with the connecting positioning member 8, the inner wall of the groove is equipped with an elastic rubber pad to prevent the second frame 2 from shaking. The first frame 1 and the second frame 2 can be flexibly folded and unfolded according to the number of blood collection tubes. In the initial state, the second frame 2 folds down to the bottom of the first frame 1, saving space. When more blood collection tubes need to be placed (e.g., Figure 1As shown, each frame has 10 rows of 8 placement holes, and each frame can accommodate blood collection tubes for 10 patients. When more than 10 patients' blood collection tubes need to be placed (the number of placement holes in the first frame 1 is insufficient), the second frame 2 is folded up to be on the same horizontal plane as the first frame 1. When the limiting blocking member 7 is rotated to the connecting positioning member 8, the U-shaped slot 15 is locked on the connecting positioning member 8, which can support and limit the second frame 2. During use, both frames are on the same horizontal plane, and the blood collection tubes will not fall off due to the folding of the frames when the blood collection frame is transferred.

[0020] Furthermore, such as Figure 1-4 As shown, to improve the stability of the blood collection tubes, both the first frame 1 and the second frame 2 are double-layered frames. The placement holes include a first placement hole 9 on one side of the double-layered frame and a second placement hole 10 on the other side of the double-layered frame, corresponding to the first placement hole 9. A positioning cylinder 11 is detachably connected to the bottom of the second placement hole 10. The positioning cylinder 11 is made of transparent plastic, allowing medical personnel to easily observe the bottom of the blood collection tube for abnormalities such as coagulation or sedimentation. The positioning cylinder 11 is connected to the second placement hole 10 via threads or magnets, facilitating disassembly, cleaning, and replacement. Figure 3 As shown, positioning rings 12 are installed inside the positioning cylinder 11 and at the inner edge of the second placement hole 10. The two positioning rings 12 are arranged along the thickness direction of the double-layer frame to limit the blood collection tube body at multiple points and prevent the blood collection tube from tilting. The positioning rings 12 are made of silicone and have an annular inner ring tooth pattern. They are elastic and can adapt to blood collection tubes of different diameters without damaging the blood collection tube. In addition, an anti-slip pad 13 is also provided inside the positioning cylinder 11. When the blood collection tube is inserted into the second placement hole 10 and placed in the positioning cylinder 11, the anti-slip pad 13 contacts the bottom of the blood collection tube, increasing the limiting effect on the blood collection tube and ensuring that the blood collection tube remains upright during the transfer process.

[0021] Furthermore, such as Figure 1-2 As shown, for patients in wards who require blood tests, unlike outpatient blood draws where labels (containing the patient's name and the test to be performed) can be easily affixed to the blood collection tubes, to facilitate differentiation of blood collection tubes for patients in different beds, a rotatable digital disk 14 is installed at the corresponding location of the first placement hole 9 in each row. This digital disk 14 is marked with different numbers to indicate the patient's bed number, allowing medical staff to quickly identify and place the corresponding patient's blood collection tube. Figure 2As shown, the digital disk 14 is rotatably connected to the double-layer frame via a central shaft. The digital disk 14 and the central shaft will not rotate when the digital disk 14 is not subjected to external force, which enables the digital disk 14 to remain stable after rotating to the designated position and not to rotate arbitrarily. A protective cover is provided on the outside of the digital disk 14. The protective cover has a notch, and the number in the notch represents the patient's bed number. In addition, each column of first placement holes 9 corresponds to two digital disks 14, which can mark the bed numbers of beds 01-99.

[0022] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
