Description

Technical Field

[0001] This utility model relates to the field of blood collection tube technology, specifically a blood collection tube with an anti-displacement positioning groove. Background Technology

[0002] In utility model patent application CN212698888U, published on March 16, 2021, entitled "A Novel Blood Collection Tube Structure," this utility model discloses a novel blood collection tube structure, belonging to the field of medical-related technology. The key technical point is a novel blood collection tube structure, including an insertion ball head and a main blood collection tube. The insertion ball head is installed at the lower end of the main blood collection tube. A labeling area is provided in the middle section of the main blood collection tube. A novel mounting and reinforcing device is added to the outer circumference of the blood collection tube near its upper side. The new mounting and reinforcement device can be quickly removed from the blood collection tube when not in use, thus not affecting the normal use of the blood collection tube. With this new mounting and reinforcement device, the blood collection tube can be placed more stably and securely on the tube rack after blood collection. Even if it is bumped into the tube rack, the blood collection tube will not easily fall off the tube rack, thus ensuring that the blood collection tube can be firmly and stably placed on the tube rack and protected by the tube rack, thereby increasing the protection and movement safety of the blood collection tube.

[0003] In the aforementioned patents or prior art, during the sampling process, blood collection tubes may deviate due to improper blood collection angle, unstable tube holding, or inertial effects caused by rapid needle withdrawal, resulting in unreliable test results, increased retesting rates and medical costs, and the needle scraping against the tube wall can easily cause hemolysis. Utility Model Content

[0004] The purpose of this invention is to provide a blood collection tube with an anti-displacement positioning groove to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a blood collection tube with an anti-displacement positioning groove, comprising a tube body, an installation block fixedly disposed inside the tube body, a groove communicating with the tube body being formed on the installation block, a tube cover being rotatably disposed on the outer surface of the installation block via a rotating assembly, a baffle being fixedly disposed on the tube cover, and a locking mechanism cooperating with the tube cover being provided on one side of the tube body.

[0006] Furthermore, the rotating assembly includes a rotating groove formed on the inner wall of the rotating ring, and the outer wall of the mounting block is provided with a rotating ring that cooperates with the rotating groove.

[0007] Furthermore, the locking mechanism includes a slot at the bottom of the tube cap, and a rod that mates with the slot is provided on one side of the tube body. The rod is installed within the mounting assembly.

[0008] Furthermore, the installation assembly includes a fixing block fixed to one side of the pipe body, the fixing block having an installation groove, a fixing plate on the fixing block, and a rod fixed above the fixing plate, and a pulling assembly at the bottom of the fixing plate.

[0009] Furthermore, the pulling assembly includes a pull rod fixed to the bottom end of the fixed plate, and the pull rod is located in the mounting groove and slidably connected to the bottom end of the fixed block. The mounting groove is provided with an elastic element that cooperates with the pull rod.

[0010] Furthermore, the elastic element includes a spring, one end of which is fixedly connected to the bottom end of the inner wall of the mounting groove, and the other end is fixed to the bottom end of the fixing plate. The spring is sleeved on the outer surface of the pull rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the blood collection tube with anti-displacement positioning groove is reasonable and has the following advantages:

[0012] (1) The blood collection tube has a unique anti-offset positioning groove design, namely the cooperation of the groove and the baffle, as well as the locking mechanism, which significantly improves the stability of the tube body during blood collection. The groove is connected to the inside of the tube body. When the tube cap is rotated until the baffle no longer covers the groove, the groove can provide a precise guiding path for the blood collection needle or sample delivery. This design ensures that the tube body remains fixed in a vertical or horizontal state, avoiding tilting or offset due to external force or improper operation. For example, if the tube body is offset during vacuum blood collection, it may lead to insufficient or excessive blood collection, or even affect the sample quality due to the collision between the needle and the tube wall. This design, through the physical limiting effect of the groove, keeps the tube body in the optimal blood collection position, thereby ensuring the accuracy of the blood collection volume. In addition, the cooperation of the insertion rod and the slot further strengthens the closed state of the tube cap, preventing the tube cap from accidentally loosening or opening during blood collection, and avoiding sample leakage or contamination. This dual stabilization mechanism is especially suitable for high-precision detection scenarios, which can reduce detection errors caused by container problems and improve the reliability of medical data.

[0013] (2) The design of the rotating and pulling components of the blood collection tube not only optimizes the operation process, but also reduces the possibility of sample contamination through physical isolation. First, the tube cap can be opened and closed flexibly through the cooperation of the rotating ring and the rotating groove. Medical staff only need to operate the lever with one hand to unlock the tube cap and rotate the baffle to expose the groove for blood collection. This design avoids the cumbersome operation of traditional screw caps or plug-in tube caps and reduces the risk of contamination caused by operation delay. Second, the spring-driven plug automatically resets when closed to ensure that the tube cap and the tube body fit tightly and form a sealed environment. For example, when collecting volatile samples, this rapid closing mechanism can effectively isolate air and prevent changes in sample composition. In addition, the baffle completely covers the groove when closed to prevent external pollutants from entering the tube body during transportation or storage. This design can reduce the sample contamination rate by more than 30%. Attached Figure Description

[0020] 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.

[0021] Please see Figure 1-5 The present invention provides a technical solution as follows:

[0022] Example 1:

[0023] A blood collection tube with an anti-displacement positioning groove includes a tube body 100, an installation block 101 fixedly disposed inside the tube body 100, a groove 102 communicating with the tube body 100 on the installation block 101, a tube cover 104 rotatably disposed on the outer surface of the installation block 101 via a rotating assembly, a baffle 105 fixedly disposed on the tube cover 104, and a locking mechanism cooperating with the tube cover 104 on one side of the tube body 100.

[0024] The rotating assembly includes a rotating groove 106 formed on the inner wall of the rotating ring 103, and the outer wall of the mounting block 101 is provided with a rotating ring 103 that cooperates with the rotating groove 106.

[0025] The locking mechanism includes a slot 107 at the bottom of the tube cap 104, and a plug 204 that mates with the slot 107 is provided on one side of the tube body 100. The plug 204 is installed in the mounting assembly.

[0026] The installation assembly includes a fixing block 200 fixed to one side of the tube body 100. The fixing block 200 has an installation groove 201. The fixing block 200 has a fixing plate 203, and the insertion rod 204 is fixed above the fixing plate 203. The bottom end of the fixing plate 203 has a pulling component.

[0027] The pulling assembly includes a pull rod 205 fixed to the bottom of the fixing plate 203, and the pull rod 205 is located in the mounting groove 201 and slidably connected to the bottom of the fixing block 200. The mounting groove 201 is provided with an elastic element that cooperates with the pull rod 205.

[0028] The elastic element includes a spring 202. One end of the spring 202 is fixedly connected to the bottom end of the inner wall of the mounting groove 201, and the other end is fixed to the bottom end of the fixing plate 203. The spring 202 is sleeved on the outer surface of the pull rod 205.

[0029] Working principle: When blood collection is required, pull down the lever 205 to move the fixing plate 203 downward, thereby disengaging the insertion rod 204 fixed at its top from the slot 107. Under the action of the rotating groove 106 and the rotating ring 103, the tube cap 104 is rotated, so that the baffle 105 no longer blocks the groove 102. The groove 102 here can ensure that the tube body 100 remains vertical or horizontal during blood collection, thereby ensuring the accuracy of blood collection. After releasing the lever 205, the fixing plate 203 moves upward under the action of the spring 202. At this point, the slot 107 has rotated to a non-aligned state along with the tube cap 104. Therefore, the insertion rod 204 will abut against the bottom of the tube cap 104 during the upward movement, which will serve as a limit. Medical personnel can then perform the sampling operation, delivering the blood sample through the groove 102 into the tube body 100. After sampling, pull the lever 205 to move the insertion rod 204 downward. Then, rotate the tube cap 104 to rotate the slot 107 to the position corresponding to the insertion rod 204. At this point, release the lever 205, and under the action of the spring 202, the insertion rod 204 will be inserted into the slot 107. Here, a limiting block that cooperates with the fixing block 200 can be set on the tube cap 104 as needed. When the limiting block is in contact with the fixing block 200, the slot 107 is exactly located on the insertion rod 204. This design can ensure stability during blood collection, avoid inaccurate sample collection due to the offset of the tube body 100, and reduce the possibility of sample contamination.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
