Description

Technical Field

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

[0002] Blood tests are a medical diagnostic procedure that involves drawing a blood sample from the body and conducting various biochemical, immunological, or genetic analyses in a laboratory. They help doctors diagnose diseases, monitor treatment effectiveness, and assess a patient's overall health. Blood tests are an indispensable part of medical diagnosis, providing doctors with crucial diagnostic information.

[0003] During the blood collection process, after disinfection, the doctor or nurse will use a blood collection needle or blood collection device to draw an appropriate amount of blood sample into the blood collection tube and send it to the laboratory for testing. For this purpose, a new type of blood collection tube is required.

[0004] Currently, blood collection tubes generally contain anticoagulants to prevent blood clotting. During blood collection, blood collection tubes and venous blood collection needles are used together. After collecting blood into the blood collection tube, medical staff need to shake it repeatedly to ensure that the anticoagulant and blood are thoroughly mixed, thus preventing clotting and facilitating subsequent testing. However, when shaking the blood collection tube, it is easy for medical staff to drop it and damage it, or for it to hit objects in the environment, causing blood leakage. This not only leads to sampling failure but may also expose doctors and nurses to the patient's blood, posing a safety hazard. On the other hand, during large-volume, intensive blood collection, doctors or nurses may inadvertently fail to mix the blood sample with the anticoagulant in every blood collection tube. Current blood collection tubes do not make it easy to identify whether the blood sample has been mixed with the anticoagulant, which may cause some blood samples to clot, making further testing impossible. Therefore, a new type of blood collection tube is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a novel blood collection tube, which aims to improve the problems in the prior art, such as the possibility of blood collection tube breakage due to shaking, and the inconvenience of identifying whether the blood sample inside the blood collection tube is mixed with anticoagulant.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a novel blood collection tube, comprising a tube body, a sealing cap rotatably connected to the outer periphery of the top end of the tube body, a sealing rubber sheet fixedly connected inside the sealing cap, an internal gear fixedly connected inside the tube body, a rotating gear meshing inside the internal gear, and a stirring assembly fixedly connected inside the rotating gear, the stirring assembly being used to stir the blood sample and anticoagulant.

[0007] As a further description of the above technical solution:

[0008] A thermal paper ring is fixedly connected to the outer periphery of the tube, a connecting rod is fixedly connected to the bottom end of the sealing cap, and an engraving block is fixedly connected to the bottom end of the connecting rod.

[0009] As a further description of the above technical solution:

[0010] The sealing cap has several sets of vertical grooves on its outer periphery.

[0011] As a further description of the above technical solution:

[0012] The stirring assembly includes a rotating shaft, the outer periphery of which is fixedly connected to the inside of a rotating gear, and stirring blades are fixedly connected to the outer periphery of the rotating shaft.

[0013] As a further description of the above technical solution:

[0014] The top of the rotating shaft is rotatably connected to the inner wall of the top of the sealing cap.

[0015] As a further description of the above technical solution:

[0016] The stirring blades form an angle of 0.5° to 3° with the central axis of the rotating shaft.

[0017] As a further description of the above technical solution:

[0018] The inner side of the engraving block is set with a sharp point.

[0019] As a further description of the above technical solution:

[0020] The etched block is located at the center line of the thermal paper ring, and the inner side of the etched block is in contact with the outer periphery of the thermal paper ring.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by setting internal gears, rotating gears and other structures, the rotating sealing cap causes the stirring component to rotate inside the tube and rotate around the sealing cap as the center. This allows the blood and anticoagulant to be mixed quickly without shaking the tube, ensuring that the tube is not easily damaged, ensuring successful sampling, and reducing safety hazards.

[0023] 2. In this utility model, by setting up a connecting rod, an engraving block and other structures, rotating the sealing cap causes the tip of the engraving block ring to wrap around the outer circumference of the thermal paper ring multiple times, leaving a straight ring mark at the outer center line of the thermal paper ring. This allows doctors or nurses to quickly identify whether the blood sample and anticoagulant inside the blood collection tube have been mixed, making it more convenient to use.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figures 1-2 This utility model provides an embodiment of a novel blood collection tube, comprising a tube body 1 for convenient blood sample collection, an anticoagulant placed inside the tube body 1, and a sealing cap 2 rotatably connected to the outer periphery of the top of the tube body 1. The sealing cap 2 ensures good airtightness between itself and the tube body 1, while the space formed between the tube body 1 and the sealing cap 2 is a vacuum negative pressure environment. Several sets of vertical grooves are formed on the outer periphery of the sealing cap 2 to increase friction and facilitate rotation of the sealing cap 2. A sealing rubber sheet 3 is fixedly connected inside the sealing cap 2 to facilitate the insertion of a blood collection needle into the interior of the tube body 1. An internal gear 4 is fixedly connected inside the tube body 1, and the internal gear 4 meshes with a... Rotating gear 5 rotates around the central axis of tube 1 and can rotate under the action of internal gear 4. A stirring assembly is fixedly connected to it. The stirring assembly is used to stir blood samples and anticoagulants. The stirring assembly includes a rotating shaft 6, which is fixedly connected to the inside of rotating gear 5 on its outer periphery. The top of rotating shaft 6 is rotatably connected to the inner wall of the top of sealing cap 2. Rotating shaft 6 is located at a non-center of sealing cap 2. Rotation of sealing cap 2 can drive rotating shaft 6 to rotate along the center of sealing cap 2. Stirring blade 7 is fixedly connected to the outer periphery of rotating shaft 6. Stirring blade 7 forms an angle of 0.5° to 3° with the central axis of rotating shaft 6 to make stirring more thorough.

[0031] Reference Figure 1 and Figure 3 A thermal paper ring 8 is fixedly connected to the outer periphery of the tube body 1. The thermal paper will leave a black mark after being scratched by a sharp object. A connecting rod 9 with a fixed connection function is fixedly connected to the bottom end of the sealing cap 2. An engraving block 10 is fixedly connected to the bottom end of the connecting rod 9. The inner side of the engraving block 10 is set with a sharp point. The engraving block 10 is located at the center line of the thermal paper ring 8. The inner side of the engraving block 10 is in contact with the outer periphery of the thermal paper ring 8. When the engraving block 10 rotates, its sharp point will leave an imprint on the outer side of the thermal paper ring 8.

[0032] Working principle: When mixing blood samples and anticoagulants after blood collection, rotate the sealing cap 2. The sealing cap 2 drives the rotating shaft 6 to rotate around the center of the sealing cap 2. At this time, the rotating shaft 6 drives the rotating gear 5 to rotate around the center of the sealing cap 2. The rotating gear 5 rotates under the action of the internal gear 4. The rotating gear 5 rotates while rotating, and the rotating shaft 6 drives the stirring blade 7 to rotate around the rotating shaft 6 and around the center of the sealing cap 2. This makes the blood and anticoagulants inside the tube 1 fully mixed without having to shake the tube 1 vigorously, ensuring that the tube 1 will not be damaged. It is relatively convenient to use. When you want to mark a blood collection tube that has been mixed with blood and anticoagulant, rotate the sealing cap 2. The sealing cap 2 causes the connecting rod 9 to rotate around the center of the sealing cap 2. The connecting rod 9 causes the imprinting block 10 to rotate around the center of the sealing cap 2. At this moment, the inner tip of the imprinting block 10 circles around the outer periphery of the thermal paper ring 8 multiple times, leaving a straight ring mark at the outer center line of the thermal paper ring 8. This allows doctors or nurses to quickly identify whether the blood sample and anticoagulant inside the blood collection tube have been mixed, making it more convenient to use.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
