Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a vacuum blood collection tube with an anti-tipping structure. Background Technology

[0002] Vacuum blood collection tubes are disposable, negative-pressure vacuum glass tubes that enable quantitative blood collection. They need to be used with a venous blood collection needle. The principle of vacuum blood collection tubes is that the capped collection tube is pre-evacuated to different degrees of vacuum, and the negative pressure automatically and quantitatively collects venous blood samples. One end of the blood collection needle is inserted into the vein, and the other end is inserted into the rubber stopper of the vacuum blood collection tube. The venous blood inside the vacuum blood collection tube is drawn into the blood sample container under negative pressure through the blood collection needle. Multiple collections can be achieved with a single venous puncture without leakage.

[0003] Application No. CN202321783132.7 discloses an anti-tipping vacuum blood collection tube, including a blood collection tube body and a sealing cap. A connecting sleeve is provided below the blood collection tube body, and a number of support components are provided on the side wall of the connecting sleeve along the circumference, which can prevent tipping and is suitable for uneven or inclined tabletops.

[0004] Existing patented vacuum blood collection tubes use several support components to prevent tipping. However, the bottom support components of these vacuum blood collection tubes have a small bottom area, resulting in poor stability when placed on a table. This makes the vacuum blood collection tubes easy to tip over and fall to the ground when placed on a table, making them inconvenient to place and use when a test tube rack is not available. Therefore, we propose a vacuum blood collection tube with an anti-tipping structure. Utility Model Content

[0005] The main objective of this invention is to provide a vacuum blood collection tube with an anti-tipping structure. A branch tube mechanism is installed outside the blood collection tube body below the cap. The outer connecting plate of the branch tube mechanism's retaining ring is supported by a vertical support plate pressed against the table surface. The two sets of plates of the triangular feet provide additional bottom contact support area at the vertical support plate. Simultaneously, a back support block is connected to the back of the connecting plate by a back slope plate and pressed against the table surface for support, ensuring stable support for the connecting plate and retaining ring by the back support block and back slope plate. The blood collection tube body, with its tube body having ribbed strips, is firmly inserted into the rubber inner ring of the retaining ring for stable support. Furthermore, a rubber suction cup below the back support block allows it to be negatively adhered to the table surface, enhancing the back support block's anti-displacement capability when supported on the table surface. When the blood collection tube body is subjected to external force, the branch tube mechanism ensures that the blood collection tube body is stably placed on the table surface and is not prone to tipping over or falling to the ground, effectively solving the problems in the prior art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A vacuum blood collection tube with an anti-tipping structure includes a blood collection tube body and a cap. The cap is installed at the opening of the blood collection tube body. It also includes a branch tube mechanism, which includes a fixed liner ring, a rubber inner ring, a connecting plate, a vertical support plate, a triangular foot, a back slope plate, a back support block, a rubber suction cup, and a side pressure plate. The blood collection tube body is inserted downward into the fixed liner ring, and a rubber inner ring is bonded to the inside of the fixed liner ring. The rubber inner ring is fitted around the outside of the blood collection tube body. A connecting plate is fixed to the edge of the fixed liner ring, and a vertical support plate is vertically fixed to the lower surface of the connecting plate. A triangular foot is fixed to the outside of the vertical support plate below the fixed liner ring, and side pressure plates are symmetrically fixed to the outer surfaces of the narrow plates on both sides of the vertical support plate. A back support block is fixed to the outer surface of the connecting plate away from the fixed liner ring and the vertical support plate through a back slope plate, and a rubber suction cup is bonded to the bottom of the back support block.

[0008] Furthermore, a bottom groove is formed on the lower plate surface of the back support block, and an adhesive rubber suction cup is inserted into the bottom groove;

[0009] By adopting the above technical solution, the rubber suction cup can be glued and installed in the bottom groove of the back support block.

[0010] Furthermore, the two sides of the vertical support plate have symmetrically protruding vertical plates on their outer surfaces, and a side pressure plate is fixed below the vertical plate.

[0011] By adopting the above technical solution, the vertical support plate can fix the side pressure plate to apply pressure to the desktop using the vertical convex plate.

[0012] Furthermore, the outer wall of the blood collection tube body has protruding tube ridges;

[0013] By adopting the above technical solution, the blood collection tube body, with its tube body having tubular ribs, can be inserted into the rubber inner ring, causing the rubber inner ring to be stretched open, ensuring that the blood collection tube body is firmly inserted into the rubber inner ring of the liner.

[0014] Furthermore, the outer wall of the rubber inner ring is bonded and fixed to the inner wall of the liner ring, and the blood collection tube body is vertically inserted inside the rubber inner ring.

[0015] By adopting the above technical solution, the rubber inner ring can be better inserted into the blood collection tube body for support after the liner ring is bonded inside.

[0016] Furthermore, two sets of triangular feet are symmetrically fixed on the surface of the vertical support plate;

[0017] By adopting the above technical solution, the vertical support plate can be pressed against the table surface to obtain support using two sets of triangular feet.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] This utility model provides a branch tube mechanism outside the blood collection tube body below the tube cap. The outer connecting plate of the branch tube mechanism is supported by a vertical support plate pressed against the table surface. The two sets of plates of the triangular plate foot provide additional bottom contact support area at the vertical support plate. At the same time, the back of the connecting plate is connected to the back support block by a back inclined plate and pressed against the table surface for support. This ensures that the back support block and the back inclined plate provide stable support for the connecting plate and the fixed ring. The blood collection tube body is firmly inserted into the rubber inner ring of the fixed ring by the tube body with tube ribs to obtain stable support.

[0020] Furthermore, the back support block is attached to the table surface by a rubber suction cup, which enhances the back support block's ability to prevent displacement when supported on the table surface. When the blood collection tube body is subjected to external force, the branch tube mechanism can ensure that the blood collection tube body is placed stably on the table surface and is not easy to tip over and fall to the ground.
