Description

Technical Field

[0001] This utility model relates to experimental consumables in the field of experimental testing technology, and in particular to a sample tube with a fixed opening angle. Background Technology

[0002] In the field of laboratory testing, laboratory operators often use centrifuge tubes, test tubes, blood collection tubes, etc. as sample tubes to hold specimens to be tested.

[0003] Currently, centrifuge tubes commonly found on the market are divided into integrated and separate types. Integrated centrifuge tubes have a cap connected to the tube body via a foldable connector. When the cap is closed, the connector is folded; when the cap is open, the connector bends or extends depending on the degree of opening. Separate centrifuge tubes generally have threads on the outer circumference of the tube opening, and corresponding threads on the inner side of the cap. The cap and tube body can be closed or opened by rotating them. Test tubes generally do not come with caps; suitable rubber or glass stoppers are typically used for sealing, while blood collection tubes are usually sealed with plastic caps containing a soft rubber core.

[0004] When conducting experimental tests, it is usually necessary for the experimenter to manually open the cap of the sample tube in advance to facilitate the removal of the specimen from the sample tube. Especially when the sample tube is used on automated testing equipment, unless blood collection tubes are used as sample tubes and the automated testing equipment has blood collection tube puncture function, the experimenter must manually open the cap of each sample tube before placing the sample tube into the automated testing equipment.

[0005] The use of automated testing equipment can significantly improve testing efficiency and is a development trend in the field of laboratory testing. However, it also requires that the sample tubes used in the testing be well-matched with the automated testing equipment. Currently, professional medical laboratory laboratories often use vacuum blood collection tubes as sample tubes, in conjunction with automated testing equipment that has puncture capabilities. Besides this, most laboratories more commonly use centrifuge tubes and test tubes as sample tubes; centrifuge tubes are the most common, especially the integrated centrifuge tubes in 1.5mL, 2mL, and 5mL sizes, which are widely used due to their compact size, ease of use, and low cost.

[0006] Existing integrated centrifuge tubes connect the tube body and cap via a foldable connector. Because this connector has some elasticity, the cap often springs back or springs open under the tension of the connector, causing the opening angle to vary and become inconsistent. When using this type of centrifuge tube as sample tubes in automated testing equipment, the inability to maintain a fixed opening angle easily leads to changes or shifts in the cap's position, potentially obstructing its own or adjacent tube openings. This affects the insertion of the sampling needle into the centrifuge tube to remove the sample, potentially causing experimental termination or abnormalities. The inability to fix the cap's opening angle in these integrated centrifuge tubes necessitates manual opening by the operator, making it extremely difficult to implement automatic cap opening on automated testing equipment. Therefore, the compatibility of existing integrated centrifuge tubes with automated testing equipment is limited, failing to adequately meet the requirements of such equipment. Utility Model Content

[0007] The main objective of this invention is to provide a sample tube with a fixed opening angle for use in experimental testing to hold and store samples. By setting a fitting position and a fitting shaft, the sample tube body and the tube cap are fitted together, allowing the opening angle of the tube cap to be fixed. This ensures that the position of the tube cap remains unchanged after opening without relying on other devices, preventing the opened tube cap from obstructing the sample tube opening. This facilitates the insertion of the sample tube by experimental operators, especially those using automated testing equipment, to remove samples. Particularly when using automated testing equipment for batch testing, the fixed opening angle of the tube caps of sample tubes arranged together prevents the caps from shifting and obstructing the sample tube openings, further facilitating the smooth and rapid removal of samples from the sample tubes and significantly improving the efficiency of automated testing.

[0008] To achieve the above objectives, this utility model proposes a sample tube with a fixed opening angle. The sample tube includes a sample tube body and a flip-openable and closable tube cap with a fitting shaft. The opening angle of the tube cap can be fixed.

[0009] The sample tube has a closed body at one end and an open body at the other end, and a base for connecting the tube cap is provided on the outer periphery of the open end of the sample tube body.

[0010] The cap and the base are connected by a fitting shaft and a fitting position.

[0011] The fitting position encloses the fitting shaft.

[0012] Optionally, the fitting position is located on the base, and the fitting shaft is located on the tube cap.

[0013] Optionally, the fitting position is located on the tube cap, and the fitting shaft is located on the base.

[0014] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0015] The cap and the base of the sample tube are connected by a fitting shaft and a fitting position. The fitting position wraps around the fitting shaft from the outside, exerting a compressive force on the fitting shaft. When the cap is opened, the relative rotation of the fitting position and the fitting shaft is subject to frictional resistance, which controls the rotation and prevents it from rotating automatically. This keeps the opening angle of the cap fixed, ensuring that the position of the opened cap does not change or move, thus avoiding obstruction of the sample tube opening. This facilitates the insertion of the sample tube opening by laboratory operators, especially those using automated testing equipment, to remove the sample. In particular, when using automated testing equipment for batch testing, the cap opening angle of the closely arranged sample tubes remains fixed, and the cap will not shift or obstruct the sample tube opening. This further helps the equipment to smoothly and quickly remove the sample from the sample tube, thereby greatly improving the efficiency of automated testing. Attached Figure Description

[0027] This invention proposes a sample tube with a fixed opening angle.

[0028] In one embodiment of this utility model, a sample tube with a fixed opening angle includes: a sample tube body 1 and a flip-openable and closable tube cap 2 with a fitting shaft, the opening angle of which is fixed; one end of the sample tube body 1 is closed and the other end is open, and a base 11 for connecting the tube cap 2 is provided on the outer periphery of the open end of the sample tube body 1. The tube cap 2 and the base 11 are fitted and connected by a fitting shaft 21 and a fitting position 12, the fitting position 12 wraps around the fitting shaft 21, the fitting position 12 is located on the base 11, and the fitting shaft 21 is located on the tube cap 2.

[0029] The present invention provides a sample tube body 1 and a tube cap 2 with a fitting shaft that can be flipped open and closed on a sample tube with a fixed opening angle. The opening angle of the tube cap 2 is fixed.

[0030] Furthermore, the sample tube body 1 is configured to be closed at one end and open at the other end, with a base 11 for connecting the tube cap 2 provided on the outer periphery of the open end of the sample tube body 1. The base 11 extends outward from the outer periphery of the open end of the sample tube body 1, providing support for the fitting connection of the tube cap 2. The base 11 is composed of two thinner sub-bases spaced apart. However, this design is not limited to this. In this embodiment, the base 11 is composed of two sub-bases spaced apart; in other embodiments, the base 11 is composed of a single integral base, achieving the same supporting effect for the fitting connection of the tube cap 2.

[0031] Furthermore, the tube cap 2 and the base 11 are connected by the fitting shaft 21 and the fitting position 12. In one embodiment, the middle part of the fitting shaft 21 is connected to the tube cap 2, and both ends of the fitting shaft 21 are protruding. The protruding parts at both ends of the fitting shaft 21 are fitted and connected to the fitting position 12. After the fitting connection, the fitting shaft 21 and the fitting position 12 are rotatable relative to each other. When the tube cap 2 is opened, the fitting shaft 21 can be rotated inside the fitting position 12. However, this design is not limited to this. In this embodiment, the middle part of the fitting shaft 21 is connected to the tube cap 2, and both ends of the fitting shaft 21 are protruding. The protruding parts at both ends of the fitting shaft 21 are fitted and connected to the fitting position 12. In other embodiments, both ends of the fitting shaft 21 are connected to the tube cap 2, the middle part of the fitting shaft 21 is not connected to the tube cap 2, and the middle part of the fitting shaft 21 is fitted and connected to the fitting position 12 to achieve the same fitting and connection effect.

[0032] Furthermore, the fitting position 12 encloses the fitting shaft 21. The fitting part 12 encloses the fitting shaft 21, exerting a squeezing force on the fitting shaft 21. When the tube cap 2 is opened, it causes the fitting shaft 21 to rotate within the fitting part 12. The squeezing force exerted by the fitting part 12 on the fitting shaft 21 causes frictional resistance when the fitting shaft 21 rotates. When the tube cap 2 is opened and stops rotating at any position, the weight of the tube cap 2 itself is less than the frictional resistance, thus controlling the rotation of the fitting shaft 21 and preventing automatic rotation. This keeps the opening angle of the tube cap 2 fixed, ensuring that the position of the opened tube cap 2 does not change or move, avoiding obstruction of the sample tube opening. This facilitates the insertion of the sample tube opening by experimental operators, especially those using automated testing equipment, to remove the sample to be tested. In particular, when using automated testing equipment for batch testing, the fixed opening angle of the tube cap 2 of the closely arranged sample tubes prevents the cap from shifting and obstructing the sample tube opening, further facilitating the smooth and rapid removal of the sample to be tested from the sample tube, thereby greatly improving the efficiency of automated testing.

[0033] Optionally, as a preferred implementation method, the fitting position 12 is located on the base 11, and the fitting shaft 21 is located on the tube cap 2. In one embodiment, the fitting position 12 is located on the base 11, which is composed of two sub-bases spaced apart by a certain distance. Each sub-base has a fitting position. The fitting shaft 21 is located on the tube cap 2, with its middle portion connected to the tube cap 2. Both ends of the fitting shaft 21 are protruding, and the protruding portions at both ends of the fitting shaft 21 can be fitted and connected to the fitting positions on the sub-bases, respectively. However, this design is not limited to this. In this embodiment, the fitting positions 12 are respectively located on the two sub-bases of the base 11, and the fitting shaft 21 is located on the tube cap 2 with both ends of the fitting shaft 21 protruding. The protruding parts are respectively fitted and connected to the fitting positions 12. In other embodiments, the fitting positions 12 are located on the base 11, which is composed of an integral base. The base 11 has only one fitting position 12. The fitting shaft 21 is located on the tube cap 2, with both ends of the fitting shaft 21 connected to the tube cap 2. The middle part of the fitting shaft 21 is not connected to the tube cap 2, and the middle part of the fitting shaft 21 is fitted and connected to the fitting position 12.

[0034] Optionally, the fitting position 12 is located on the tube cap 2, and the fitting shaft 21 is located on the base 11. In one embodiment, the fitting position 12 is located on the tube cap 2, and the fitting position 12 is composed of two sub-fitting positions spaced apart by a certain distance. The fitting shaft 21 is located on the base 11, and the middle part of the fitting shaft 21 is connected to the base 11. The two ends of the fitting shaft 21 are protruding, and the protruding portions at both ends of the fitting shaft 21 can be fitted and connected to the two sub-fitting positions of the fitting position 12 respectively. However, this design is not limited to this. In this embodiment, the fitting position 12 is located on the tube cap 2 and consists of two sub-fitting positions. The fitting shaft 21 is located on the base 11 and both ends of the fitting shaft 21 are protruding. The protruding parts are fitted and connected to the fitting position 12. In other embodiments, the fitting position 12 is located on the tube cap 2 and is composed of an integral fitting position.
