Description

Technical Field

[0001] This application relates to the field of experimental equipment technology, and in particular to a test tube carrier. Background Technology

[0002] Biological samples need to be sealed and stored for a period of time after testing so that they can be reused if further verification is required. For example, after a blood sample is tested in a test tube, the tube is sealed and stored. If there are any doubts about the test results later, the relevant sample tube can be removed for verification. Usually, the test tubes are sealed with a membrane after testing before storage to prevent liquid leakage and cross-contamination, as well as the hazards caused by aerosol spills.

[0003] In related technologies, the tested sample tubes are placed on a test tube rack, and then the test tube rack is moved to a sealing machine. The sealing device of the sealing machine moves the sealing film downward to the mouth of the test tube to cover the mouth of the test tube. Then, the waste film between different test tubes is cut downward by a cutter. However, when the cutter moves upward after cutting off the waste film, it is easy to pull the sample test tubes out of the test tube rack, which may cause the sample test tubes to collide with the cutter or be stuck by the cutter when the test tube rack is transferred. Utility Model Content

[0004] To address or partially address the problems existing in the related technologies, this application provides a test tube carrier that can increase the resistance to sample test tubes and prevent the sample test tubes from being carried out by the cutter.

[0032] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0033] like Figures 1 to 4 As shown, this application embodiment provides a test tube carrier, including a base 1. The base 1 has multiple placement holes 11 for sample test tubes to pass through. The placement holes 11 penetrate the base 1. One end of the placement hole 11 is provided with a clamping member 2 connected to the base 1. The clamping member 2 has a clamping groove communicating with the placement hole 11. The side wall of the clamping groove is provided with an elastic clamping piece 21. After the sample test tube passes through the placement hole 11, it extends into the clamping groove and can be clamped by the elastic clamping piece 21. In use, the clamping member 2 is located at the lower end of the placement hole 11, and the clamping groove is coaxially arranged with the placement hole 11. The sample test tube passes downward through the placement hole 11 and enters the clamping groove, and the elastic clamping piece 21 presses against the side wall of the sample test tube.

[0034] The substrate 1 has a receiving cavity, and within the receiving cavity is an elastic sleeve 3 coaxially arranged with the placement hole 11. The inner diameter of the elastic sleeve 3 is smaller than the diameter of the placement hole 11. The diameter of the placement hole 11 can be slightly larger than the diameter of the sample tube, for example, 0.1 mm larger, to facilitate the insertion of the sample tube into the placement hole 11. The inner diameter of the elastic sleeve 3 can be slightly smaller than the diameter of the sample tube, for example, 0.1 mm smaller, so that when the elastic sleeve 3 is fitted onto the sample tube, it can be slightly expanded and deformed by the sample tube, thus providing a certain clamping force on the sample tube.

[0035] By setting an elastic clip 21 in the clamping groove, the elastic clip 21 clamps and positions the sample tube. By setting an elastic sleeve 3 in the receiving cavity, the elastic sleeve 3 is placed on the sample tube after the sample tube passes through the placement hole 11, thereby further limiting the position of the sample tube. When the cutter is lifted, the sample tube is subjected to the frictional force of the elastic clip 21 and the elastic sleeve 3, thereby increasing the resistance and preventing it from being lifted upward by the cutter.

[0036] Specifically, the substrate 1 is basically rectangular, with placement holes 11 penetrating vertically through it. Clamping members 2 are vertically positioned on the lower surface of the substrate 1 and fixedly connected to it. Clamping members 2 are basically columnar, with notches on their sidewalls at the locations where elastic clips 21 are positioned, and the elastic clips 21 are located within these notches. An elastic sleeve 3 is confined within the receiving cavity. Multiple placement holes 11 and clamping members 2 are provided, with each pair corresponding to the other, allowing the test tube holder to hold multiple sample test tubes.

[0037] In some embodiments, such as Figures 1 to 3 As shown, multiple placement holes 11 are arranged in multiple rows and columns, and each placement hole 11 is provided with an elastic sleeve 3. In the figure, the placement holes 11 are arranged in 5 rows and 10 columns. The test tube carrier can hold a total of 50 sample test tubes. Correspondingly, there are also 50 clamping parts 2.

[0038] In this arrangement, multiple elastic sleeves 3 in each column are connected sequentially, with at least two columns of elastic sleeves 3 forming a group. Within each group, the elastic sleeves 3 in adjacent columns are connected one-to-one. That is, in each group, each elastic sleeve 3 is connected to other elastic sleeves 3 in the adjacent row and column. The diagram shows two columns of elastic sleeves 3 as a group; specifically, as shown... Figure 4 As shown, Figure 4 The two rows of elastic sleeves 3 shown in the figure are a group, and there are a total of 5 groups of elastic sleeves 3 in the test tube carrier, with 10 elastic sleeves 3 in each group.

[0039] By dividing the elastic sleeve 3 into multiple groups, each group of elastic sleeve 3 is a whole, which facilitates manufacturing and installation, eliminating the need for manufacturing and installing individual elastic sleeve 3.

[0040] In some embodiments, such as Figure 3 and 4 As shown, two adjacent elastic sleeves 3 are connected by a connecting plate 4. The connecting plate 4 is elastic, and connecting adjacent elastic sleeves 3 with the elastic connecting plate 4 can improve the elastic deformation capacity of the elastic sleeves 3. When the elastic sleeves 3 deform, the connecting plate 4 also provides a certain force to the elastic sleeves 3. When the elastic sleeves 3 expand, the elastic sleeves 3 need to compress the connecting plate 4 to deform them, thereby increasing the force of the connecting plate 4 on the elastic sleeves 3 in clamping the sample tube. Under the action of the connecting plate 4, the elastic sleeves 3 are more likely to contract and return to their natural state.

[0041] In some embodiments, the elastic sleeve 3 and the connecting plate 4 are integrally formed structures. Of course, the elastic sleeve 3 and the connecting plate 4 can also be connected by bonding, melting, or other methods.

[0042] In some embodiments, both the elastic sleeve 3 and the connecting plate 4 are made of rubber material and have a certain elastic deformation capability.

[0043] In some embodiments, such as Figure 3As shown, the cavity is provided with a limiting member 12 for limiting the elastic sleeve 3. Specifically, the limiting member 12 can be a plate-like structure provided on the base 1. Straight plates can be provided between different groups of elastic sleeves 3 to separate adjacent groups of elastic sleeves 3, and arc-shaped plates can be provided around each elastic sleeve 3 to limit the elastic sleeve 3.

[0044] In some embodiments, such as Figure 1 As shown, the substrate 1 is also provided with an insertion hole 13 penetrating the substrate 1. A pressing block 5 is provided between the insertion hole 13 and the elastic sleeve 3. One end of the pressing block 5 abuts against the elastic sleeve 3, and the other end of the pressing block 5 is located inside the insertion hole 13. The pressing block 5 is located inside the receiving cavity of the substrate 1.

[0045] Specifically, the test tube holder can be used for the process of removing caps from sample test tubes. The sample test tubes to be decapped are placed in the test tube holder, and then the test tube holder is placed in the decapping machine. The decapping machine's insert rod is inserted downwards into the insertion hole 13, as shown below. Figure 3 As shown, when the insert rod is inserted downwards, it presses the end of the pressure block 5 located inside the insertion hole 13, causing the pressure block 5 to move horizontally. This presses against the side wall of the elastic sleeve 3, causing the elastic sleeve 3 to deform inwards and clamp the sample tube. Thus, when the capping machine removes the cap from the sample tube, the sample tube will not come out due to the clamping of the pressure block 5 by the elastic sleeve 3, thereby successfully completing the cap removal. When the insert rod moves upwards, the pressure block 5 returns to its original position under the elastic action of the elastic sleeve 3.

[0046] Each elastic sleeve 3 is connected to other adjacent elastic sleeves 3 in the same group. In this way, after the insertion rod moves upward, the elastic sleeve 3 can more easily return to its original shape when it recovers its deformation under the action of the connecting plate 4. The pressing block 5 can be made of rubber material and has a certain degree of elasticity.

[0047] In some embodiments, such as Figure 1 and Figure 3 As shown, each insertion hole 13 corresponds to a plurality of placement holes 11, and the plurality of placement holes 11 surround the corresponding insertion hole 13. The plurality of pressing blocks 5 corresponding to the plurality of placement holes 11 surrounding the corresponding insertion hole 13 converge within the corresponding insertion hole 13. Specifically, the plurality of placement holes 11 surround the corresponding insertion hole 13, that is, the plurality of elastic sleeves 3 surround the corresponding insertion hole 13. Each elastic sleeve 3 is respectively provided with a pressing block 5, so that one end of the plurality of pressing blocks 5 converges within the corresponding insertion hole 13. When the insertion rod is inserted downward into the insertion hole 13, the insertion rod simultaneously drives the plurality of pressing blocks 5, causing the plurality of pressing blocks 5 to compress the plurality of elastic sleeves 3.

[0048] like Figure 1 , Figure 3 and Figure 4As shown in the illustrated embodiment, each insertion hole 13 corresponds to four placement holes 11. The four placement holes 11 are arranged around one insertion hole 13, that is, four elastic sleeves 3 are arranged around one insertion hole 13. The four elastic sleeves 3 are located in the same group. There is an insertion hole 13 between each two adjacent rows of elastic sleeves 3. Each insertion hole 13 is provided with four pressing blocks 5, and the four pressing blocks 5 correspond to the four elastic sleeves 3.

[0049] In some embodiments, such as Figure 2 As shown, one end of the insertion hole 13 is provided with an insertion tube 6 connected to the base 1, and the insertion tube 6 is provided with a slot communicating with the insertion hole 13. Specifically, the insertion tube 6 is fixedly provided on the lower surface of the base 1, and the insertion rod passes downward through the insertion hole 13 and extends into the slot of the insertion tube 6. The insertion tube 6 plays a guiding and protective role for the insertion rod.

[0050] In some embodiments, such as Figure 1 and Figure 2 As shown, the substrate 1 includes an upper cover 14 and a lower cover 15 connected to the upper cover 14, the upper cover 14 and the lower cover 15 forming a receiving cavity. The upper cover 14 covers the lower cover 15, and the upper cover 14 and the lower cover 15 can be made of plastic injection molding.

[0051] In some embodiments, such as Figures 1 to 3 As shown, the side of the substrate 1 is provided with a handle 16 that protrudes from the substrate 1 in a horizontal direction. The handle 16 can facilitate the removal of the test tube rack from the storage rack, and can also be used to identify the direction of the test tube rack, preventing the wrong sample test tube from being taken from the rack due to incorrect identification of the direction of the test tube rack.
