Description

Technical Field

[0001] This utility model belongs to the field of test tube rack technology, specifically relating to a multi-purpose blood collection test tube rack. Background Technology

[0002] A crucial diagnostic tool in modern medicine is examination. By examining a patient's clinical symptoms and using the results of examinations, doctors can diagnose diseases earlier and more accurately. Blood is the most commonly used specimen in laboratory tests. Blood contains many indicators that can very sensitively and accurately reflect bodily functions and health status. When drawing blood, after verifying the test items, the nurse prepares the blood collection tubes to collect the blood, and then places the blood collection tubes in a test tube rack.

[0003] For example, Chinese utility model patent No. 201920848206.8, published on March 31, 2020, discloses a blood collection tube rack, including multiple individual racks and a placement rack. The placement rack has a groove with a top opening, and the individual racks are evenly distributed in the groove. A vertical guide structure is provided between the individual racks and the side wall of the groove. A push button is connected to the outside of the individual racks. A culture tank, a specimen storage tank, and multiple first tanks are arranged sequentially on the outside of the groove. This utility model can effectively solve the problem that the existing blood collection tube racks cannot meet the needs of daily care and that the blood collection tubes may be mistakenly removed from the rack.

[0004] However, this invention still has drawbacks. While it solves the problem of incorrectly removing blood collection tubes from the stent, existing methods require different equipment for testing due to varying patient conditions, such as finger-prick blood or venous blood. The specific blood collection method depends on the testing requirements, and different volumes necessitate different blood collection tubes, resulting in varying tube lengths. Since the groove depth for the blood collection tube stent is fixed, shorter tubes may be inserted too deeply, leading to significant differences in their tip height. This not only makes it difficult to remove the shorter tubes, affecting efficiency, but also carries the risk of sample confusion. This not only affects testing accuracy but can also lead to medical accidents, such as transfusion errors or incorrect case reports. Utility Model Content

[0025] This specific embodiment is a multi-purpose blood collection tube rack. In practical work, the applicant discovered a risk of sample confusion after blood collection. Upon careful investigation, the applicant found that this problem stems from the different tube sizes, such as the common 75mm and 100mm sizes; the length difference is 25mm. Typically, about one-third of a blood collection tube is exposed. This means that when a 75mm tube is placed in a 100mm groove, the exposed portion is less, making it difficult to identify the identification labels affixed to the tubes. These labels contain patient information, blood collection time, and tube type, and are intended for identification by testing personnel or equipment. If the tube is inserted too deeply into the groove, there is a risk of sample confusion due to label misidentification. Sample confusion can lead to serious medical accidents, such as transfusion errors or incorrect medical reports. To solve this problem, the applicant developed the blood collection tube rack of this application, as follows:

[0026] Its structural diagram is as follows Figures 1-6 As shown, the test tube rack includes a base plate 1. A left side plate 2 and a right side plate 3 are fixedly connected to the left and right sides of the upper surface of the base plate 1, respectively. A placement plate 4 is fixedly connected to the top of the left side plate 2 and the right side plate 3. The placement plate 4 has multiple test tube placement holes 5. An auxiliary plate 6 is rotatably connected to the upper surface of the left side plate 2 and the right side plate 3. An auxiliary hole 7 corresponding to the test tube placement hole 5 is opened on the auxiliary plate 6. A connecting plate 8 is fixedly connected between the front and rear sides of the left side plate 2 and the right side plate 3. A movable base plate 10 is set on the left and right sides of the connecting plate 8 through an up-and-down adjustment component 9. A placement groove 11 corresponding to the test tube placement hole 5 is opened on the movable base plate 10 and the middle of the base plate 1. An auxiliary groove 12 corresponding to the auxiliary hole 7 is opened on the inner bottom wall of the placement groove 11. The diameter of the placement groove 11 is larger than the size of the auxiliary groove 12, thereby limiting the bottom of thicker and thinner test tubes, so that the test tubes can be kept upright, avoiding the test tubes tilting and affecting the observation of the label, thus facilitating label identification and avoiding the confusion of samples.

[0027] like Figure 1 and Figure 2 As shown: In this embodiment, the top of both the left side plate 2 and the right side plate 3 are provided with mounting grooves 13, and the front and rear sides of the auxiliary plate 6 are rotatably connected to the inner wall of the mounting groove 13 through a rotating shaft 14.

[0028] In this way, the auxiliary plate 6 can rotate around the pivot 14 until the auxiliary plate 6 is in contact with the placement plate 4, so that shorter test tubes can be placed, or all long test tubes can be placed, making it more flexible to use.

[0029] like Figure 1 and Figure 6As shown: In this embodiment, magnets 601 are fixedly connected to both the front and rear ends of the right side of the auxiliary plate 6. The magnets 601 pass through the upper and lower sides of the auxiliary plate 6. The left and right sides of the upper surface of the placement plate 4 are fixedly connected to the first iron pieces 602 corresponding to the magnets 601. The sides of the left side plate 2 and the right side plate 3 that are far apart are fixedly connected to the second iron pieces 603 corresponding to the magnets 601. The auxiliary plate 6 has a handle groove 604 on the side of the magnet 601. The handle groove 604 allows the auxiliary plate 6 to rotate around the pivot 14 and fit against the placement plate 4. At this time, the magnets 601 and the first iron pieces 602 are attracted together, preventing random movement and improving stability. When placing the test tube, the test tube remains stable, preventing the test tube from tilting and affecting the observation of the label.

[0030] like Figure 1 and Figure 2 As shown: In this embodiment, the up-down adjustment component 9 includes elongated holes 901 on the left and right sides of the connecting plate 8. Movable rods 902 are fixedly connected to the front and rear sides of the movable base plate 10. The other end of the movable rod 902 passes through the elongated hole 901 and is fixedly connected to a movable block 903. A positioning screw 904 is threaded onto the movable block 903. The upper and lower sides of the connecting plate 8 are respectively provided with an upper positioning groove 905 and a lower positioning groove 906 corresponding to the positioning screw 904.

[0031] By loosening the positioning screw 904 to disengage it from the lower positioning groove 906, the movable base plate 10 is moved upward along the elongated hole 901. Then, the positioning screw 904 is tightened and inserted into the upper positioning groove 905, thereby adjusting the height of the movable base plate 10. This allows the test tube rack to accommodate test tubes of different lengths. In other words, by adjusting the height of the movable base plate 10, the top height of different test tubes can be kept consistent, making it easier to remove shorter test tubes, improving work efficiency, and facilitating the observation of labels on the test tubes. This also avoids medical accidents caused by misidentification and sample confusion.

[0032] like Figure 3 and Figure 4 As shown: In this embodiment, a first protective sleeve 501 is fixedly connected to the inner wall of the test tube placement hole 5, and a second protective sleeve 701 is fixedly connected to the inner wall of the auxiliary hole 7; the first protective sleeve 501 and the second protective sleeve 701 can be made of rubber and have a certain elasticity, so that they can be well fixed when the test tube is inserted, so that the test tube remains stable. This will prevent the test tube from tilting and making it difficult to observe the label. At the same time, the rubber protective sleeve 501 will not damage the surface of the test tube.

[0033] like Figure 1 and Figure 3As shown: In this embodiment, stepped grooves 907 are provided on both the left and right sides of the lower surface of the base plate 1. The depth of the stepped grooves 907 is the same as the thickness of the movable base plate 10. In this way, the movable base plate 10 can be flush with the base plate 1 after it is moved to the bottom. At this time, test tubes of the same length can be placed at the same time, so that there will be no difference in the height of the top, and it is not easy to cause medical accidents caused by sample confusion.

[0034] like Figure 1 As shown: In this embodiment, anti-slip seats 101 are fixedly connected to the four corners of the lower surface of the base plate 1. The anti-slip seats 101 are made of rubber. The anti-slip seats 101 improve the stability of the test tube rack when it is placed, and prevent slippage. This makes the blood collection tubes placed on the test tube rack stable, making it easier to observe the labels on the test tubes and thus making it easier for staff to pick up the test tubes.

[0035] Working principle: When a shorter test tube needs to be placed, the auxiliary plate 6 is rotated around the pivot 14 via the handle groove 604 until the auxiliary plate 6 is in contact with the placement plate 4. At this time, the magnet 601 and the first iron piece 602 are attracted together to prevent random movement. Then, the positioning screw 904 is loosened to disengage from the lower positioning groove 906. Next, the movable base plate 10 is moved upward along the elongated hole 901, and then the positioning screw 904 is tightened and inserted into the upper positioning groove 905 to adjust the height of the movable base plate 10. At this time, a shorter test tube can be inserted through the auxiliary hole 7, and a longer test tube can be inserted through the middle test tube placement hole 5. This makes the height of the top of the shorter test tube the same as the height of the top of the longer test tube, which not only makes it easy to take out the shorter test tube, but also makes it easy to identify the labels on the shorter and longer test tubes. This ensures that there is no risk of sample confusion after blood collection and avoids medical accidents.

[0036] All technical features in this embodiment can be freely combined according to actual needs.

[0037] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
