Description

Technical Field

[0001] This utility model relates to the field of sampling tube technology, specifically a novel blood sampling tube. Background Technology

[0002] Clinical blood testing is an indispensable part of medical diagnosis, mainly encompassing general blood tests, laboratory testing for hemolytic anemia, bone marrow cytology, blood typing, and crossmatching. Blood sampling tubes, as crucial instruments for blood sample collection, preservation, and transportation, directly impact sample quality and the reliability of test results. Currently, most commercially available blood sampling tubes require additional storage boxes, often causing inconvenience during use. Furthermore, these tubes lack effective securing measures during transportation and carrying, making them susceptible to external disturbances, leading to slippage or breakage. This not only threatens the integrity of the blood sample but may also delay the testing process.

[0003] Patent CN220588264U discloses a portable blood sampling tube, including a placement rack. A fixing block is located inside the placement rack, and a sampling tube is positioned at the center of the fixing block. A clamp is located outside the sampling tube, and a support block is fixedly connected to the outer surface of the clamp. A fixing seat is located on the right side of the support block, and a sliding rod is located inside the support block. A limit plate is fixedly connected to the left side of the sliding rod. This invention uses a clamp to place the sampling tube within the fixing block. Because the clamp is angled, the sampling tube presses against the clamp upon contact. The elasticity of a spring ensures the clamp and sampling tube are tightly fitted, providing easy fixation of the sampling tube. It also cushions the sampling tube during bumpy conditions, effectively protecting it from breakage. Furthermore, placing the sampling tube within the placement rack keeps it neat and tidy.

[0004] However, the existing technologies mentioned above, while achieving the fixation of the sampling tube, also have certain limitations. While the clamping plate and spring structure can provide some cushioning and fixation, the reliance on the elasticity of the spring to provide the clamping force between the clamp and the sampling tube can easily generate excessive lateral pressure on the tube. During use, especially in the placement and removal of the sampling tube, workers need to overcome significant resistance, increasing operational complexity and reducing work efficiency. Furthermore, the numerous components used for compression and positioning make the fixation structure overly complex. Therefore, we propose a novel blood sampling tube. Utility Model Content

[0005] The purpose of this invention is to provide a novel blood sampling tube to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A novel blood sampling tube includes a temporary support. The top of the temporary support has multiple circular grooves arranged equidistantly to the left and right for neatly placing the blood sampling tube, facilitating its storage and management. The blood sampling tube is placed in the circular grooves. A first annular anti-detachment block is provided on the upper middle part of the outer wall of the blood sampling tube to prevent it from moving upward or shaking. A second annular anti-detachment block is provided on the outer wall of the blood sampling tube near the bottom to prevent it from sliding down or shifting.

[0008] The upper middle part of the inner wall of the circular groove is provided with four first rubber positioning pieces arranged in a ring array. By elastically adhering to the outer wall of the blood sampling tube, they provide a buffering effect and further enhance the fixation effect of the sampling tube. The first rubber positioning pieces have a first V-shaped groove on one side of the outer wall of the blood sampling tube to restrict the movement of the sampling tube. The inner wall of the circular groove and near the bottom are provided with two second rubber positioning pieces arranged symmetrically on the left and right. By adhering to the outer wall of the sampling tube, they provide additional support and buffering. The second rubber positioning pieces have a second V-shaped groove on one side of the outer wall of the blood sampling tube to further enhance the stability of the sampling tube.

[0009] Preferably, the blood sampling tube has a sealing cap at the top, and the top of the sealing cap has a slot for needle puncture, which facilitates the acquisition of blood samples by needle puncture during the sampling process, while maintaining the sealing of the sampling tube. A protective cap is fitted on the outside of the sealing cap to prevent the sealing cap from being damaged or contaminated by external forces. The middle of the top of the inner wall of the protective cap has a plug that inserts into the slot, further enhancing the protective effect of the sealing cap and preventing dust from entering the slot.

[0010] Preferably, the outer wall of the first annular anti-detachment block abuts against the inner wall of the first V-shaped groove to fix the upper part of the sampling tube and limit its shaking or upward movement. The outer wall of the second annular anti-detachment block abuts against the inner wall of the second V-shaped groove to prevent it from sliding upward and enhance stability.

[0011] Preferably, the bottom of the inner wall of the circular groove is provided with an arc-shaped bottom groove, and a rubber liner is bonded to the concave surface of the arc-shaped bottom groove. The bottom end of the blood sampling tube abuts against the concave surface of the rubber liner, which is used to provide buffering and shock absorption protection for the bottom end of the blood sampling tube, and further enhance the stability of the bottom of the sampling tube.

[0012] Preferably, the temporary stent has a first rectangular opening and a second rectangular opening on its front side, with the first rectangular opening located above the second rectangular opening, forming a hollow structure for the temporary stent. This reduces the overall weight of the stent, making it easier to carry and use, and also makes it easier for staff to observe the blood sampling tube.

[0013] Preferably, the temporary support is provided with anti-slip pads at the bottom and near the left and right sides. The anti-slip pads are bonded to the temporary support to prevent the temporary support from sliding when placed on a flat surface and to improve the stability of the support.

[0014] Preferably, the temporary support is rotatably connected to a handle, and the handle is covered with a rubber sleeve to facilitate workers to carry the support.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This novel blood sampling tube, by setting a first annular anti-detachment block and a second annular anti-detachment block, which respectively cooperate with the first V-shaped groove on the first rubber positioning plate and the second V-shaped groove on the second rubber positioning plate, can effectively limit the movement of the blood sampling tube in the longitudinal and lateral directions, prevent it from being displaced or sliding due to shaking, and greatly improve the stability of the sampling tube, making it particularly suitable for use in transportation or bumpy environments.

[0017] 2. This new blood sampling tube has a sealing cap at the top, and the slot at the top facilitates needle puncture and sampling while maintaining a sealing function. A protective cap is fitted on the outside of the sealing cap, and the insert block inside the protective cap is inserted into the slot to further enhance the sealing effect. This design not only prevents blood sample leakage, but also prevents external dust or contaminants from entering the sampling tube, ensuring sample quality.

[0018] 3. This new blood sampling tube uses a combination of annular anti-detachment block and rubber positioning piece, which simplifies the fixing structure of the sampling tube. Compared with the fixing method of the prior art that relies on complex structures such as springs, the operation is simpler and faster. When the staff picks up and puts down the sampling tube, they do not need to overcome too much resistance, thereby improving the operation efficiency and work convenience.

[0019] 4. The new blood sampling tube has a first rectangular opening and a second rectangular opening on the front of the temporary support, forming a hollow structure, which reduces the overall weight of the support and makes it convenient for staff to observe the status of the blood sampling tube at any time. In addition, the bottom of the support is equipped with an anti-slip pad to enhance the stability of placement, and the outside is equipped with a handle with a rubber sleeve for easy carrying by staff.

[0028] Please see Figures 1-5 This utility model provides a technical solution:

[0029] A novel blood sampling tube includes a temporary support 1. The top of the temporary support 1 has multiple circular grooves 10 arranged equidistantly to the left and right for neatly placing the blood sampling tube 2, which facilitates the storage and management of the sampling tube.

A second annular anti-detachment block 22 is provided in the outer wall of the blood sampling tube 2 near the bottom to prevent the blood sampling tube 2 from sliding down or shifting.

[0030] The upper middle part of the inner wall of the circular groove 10 is provided with four first rubber positioning pieces 4 arranged in a ring array. By elastically adhering to the outer wall of the blood sampling tube 2, they provide a buffering effect and further enhance the fixation effect of the sampling tube. The first rubber positioning pieces 4 have a first V-shaped groove 40 on one side of the outer wall of the blood sampling tube 2 to restrict the movement of the sampling tube. The inner wall of the circular groove 10 and near the bottom are provided with two second rubber positioning pieces 5 arranged symmetrically on the left and right. By adhering to the outer wall of the sampling tube, they provide additional support and buffering.
