Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to an adapter. Background Technology

[0002] Sample tubes, such as blood collection tubes or centrifuge tubes, can be used to hold biological sample suspensions. Under high-speed rotation and the action of huge centrifugal force, the suspended microparticles (such as organelles, biological macromolecules, etc.) settle at a certain speed, thereby separating them from the solution.

[0003] like Figure 1 As shown, the sample tube includes a tube body and a cap connected to the open end of the tube body. The cap can rotate relative to the tube body, so that the cap can be conveniently placed on the open end of the tube body.

[0004] Sample tubes are typically placed into the sample slots of a sample holder, which is then placed in a centrifuge for centrifugation. Because sample tubes come in different diameters, for example, a sample holder may be suitable for standard blood collection tubes but not for tubes like... Figure 2 The 1.5ml or 2ml centrifuge tubes shown are small in size, but when the diameter of the sample well is larger than the diameter of the sample tube, the sample well cannot support the sample tube. Therefore, sample racks of different sizes are needed to accommodate the sample tubes, which increases the testing cost.

[0005] Chinese patent application number 202223116019.1 discloses a centrifuge tube magnetic holder. Although the fastening components provided can be used for centrifuge tubes of different diameters, the centrifuge tube magnetic holder cannot fix the cap of the centrifuge tube when the opening of the tube needs to be open, causing the cap to block the opening, affecting the injection or extraction of liquid into the tube, and thus affecting the detection efficiency.

[0006] The purpose of this invention is to provide an adapter to at least solve one of the aforementioned technical problems.

[0007] To achieve the above objectives, this utility model provides an adapter configured to be disposed between a sample tube and a sample holder, wherein the sample tube includes a tube body and a cap; the adapter includes:

[0008] The adapter body is a hollow tube with an opening at the top for inserting a sample tube, and the adapter body can be inserted into the sample slot of the sample holder;

[0009] A cover fixing part is connected to the top of the adapter body and located on one side of the top opening of the adapter body. The cover fixing part is configured to fix the cover.

[0010] Optionally, the cover fixing part includes a front stop and a rear stop, both of which are connected to the top of the adapter body and are radially spaced along the adapter body. The front stop has a slot configured to receive a connecting part, and the cover is located between the front stop and the rear stop. The tube body and the cover are connected through the connecting part. The cover includes a cover body and a sealing part, which is connected to the inside of the cover body.

[0011] Optionally, the cover fixing part further includes a connecting block, through which the front stop and the rear stop are connected.

[0012] Optionally, the sides of the front stop and the rear stop that are close to each other are both vertical surfaces.

[0013] Optionally, the height of the front stop is greater than the height of the rear stop, the front stop is configured to block the inner side of the cover body, and the rear stop is configured to block the outer side of the cover body.

[0014] Optionally, the distance between the front stop and the rear stop is greater than the thickness of the cover body.

[0015] Optionally, the front stop includes a first baffle and a second baffle spaced apart, with the slot formed between the first baffle and the second baffle.

[0016] Optionally, the width of the slot is greater than the width of the connecting portion.

[0017] Optionally, the upper ends of the first baffle and the side of the second baffle that are close to each other are provided with clearance notches.

[0018] Optionally, the diameter of the circumference where the clearance notch is located is smaller than the diameter of the circumference where the outer periphery of the cover body is located.

[0019] Optionally, the adapter further includes a first positioning rib, which is connected to the outer wall of the adapter body, and the lower end of the first positioning rib is configured to abut against the upper surface of the sample holder.

[0021] Optionally, the sample holder has a slot, which communicates with the sample slot;

[0022] The adapter further includes two second positioning ribs, which are respectively connected to the outer wall of the adapter body and are spaced apart along the circumference of the adapter body. The side of the two second positioning ribs that is far apart from each other is configured to abut against the groove wall of the slot.

[0023] As can be seen from the above, the technical solution provided by this utility model allows the use of the adapter provided in this application when the outer diameter of the sample tube is smaller than the inner diameter of the sample well. When using the adapter, insert the adapter body into the sample well, then insert the sample tube into the adapter body, and fix the cap to the cap fixing part to avoid the cap blocking the opening of the tube body, thereby smoothly injecting or extracting liquid from the tube body and improving detection efficiency.

[0024] The cap fixing part can also restrict the rotation of the sample tube relative to the adapter, improving the stability of the sample tube. The sample tube can be interference-fitted or clearance-fitted with the adapter body.

[0043] This embodiment provides an adapter for fixing sample tubes 20 such as centrifuge tubes, but is not limited thereto, to adapt to smaller sample tubes 20 and to prevent the cap 201 from blocking the opening of the tube body 204, thereby facilitating the injection or extraction of liquid into or from the sample tube 20 and improving detection efficiency.

[0044] like Figure 3 As shown, the adapter provided in this embodiment is configured to be placed between the sample tube 20 and the sample holder 10 so that the sample tube 20 is adapted to the sample slot 101 of the sample holder 10.

[0045] like Figure 1 As shown, the sample tube 20 includes a tube body 204 and a cap 201. The sample tube 20 may also include a connecting part 203, which is located on one side of the tube body 204 in the radial direction. The tube body 204 and the cap 201 are connected through the connecting part 203. Specifically, one end of the connecting part 203 in the radial direction is connected to the tube body 204, and the other end is rotatably connected to the cap 201.

[0046] Specifically, the sample tube 20 is made of materials such as epoxy resin (EP), and the thickness of the connection between the connecting part 203 and the cover 201 can be relatively thin, thereby realizing the rotational connection between the connecting part 203 and the cover 201.

[0047] Optionally, the cover 201 includes a cover body 202 and a sealing part 205, the sealing part 205 being connected to the inner side of the cover body 202. The sealing part 205 is used to seal the opening of the tube body 204. For example, the sealing part 205 can be a plug, which is inserted into the opening of the tube body 204 to seal the tube body 204; the sealing part 205 can also be an annular member, which is fitted around the outer periphery of the opening of the tube body 204 to seal the tube body 204.

[0048] like Figure 4 As shown, the adapter includes:

[0049] The adapter body 1 is a hollow tube with an opening at the top for inserting the sample tube 20. The adapter body 1 can be inserted into the sample slot 101 of the sample holder 10.

[0050] The cover fixing part 2 is connected to the top of the adapter body 1 and is located on one side of the top opening of the adapter body 1. The cover fixing part 2 is configured to fix the cover 201.

[0051] When the outer diameter of the sample tube 20 is smaller than the inner diameter of the sample groove 101, the adapter provided in this embodiment can be used. When using the adapter, insert the adapter body 1 into the sample groove 101, then insert the sample tube 20 into the adapter body 1, and fix the cap 201 to the cap fixing part 2 to avoid the cap 201 blocking the opening of the tube body 204, thereby smoothly injecting liquid into the inner tube body 204 or taking liquid out of the tube body 204, improving detection efficiency.

[0052] The cap fixing part 2 can also restrict the rotation of the sample tube 20 relative to the adapter, improving the stability of the sample tube 20. The sample tube 20 can be interference-fitted or clearance-fitted with the adapter body 1.

[0053] The adapter provided in this embodiment has high compatibility, and is compatible with both sample tubes 20 with and without caps 201, reducing usage costs. For example, the adapter can be used with common 1.5ml and 2ml centrifuge tubes. The adapter is easy to install, making it convenient to switch between regular blood collection tubes and centrifuge tubes on the sample rack 10. For instance, when centrifuge tubes are needed, the adapter can be manually installed on the existing sample rack 10, and manually removed after use.

[0054] Optionally, the bottom of the adapter body 1 may also have an opening, and the tube 204 may pass through the opening at the top and the opening at the bottom of the adapter body 1 (e.g., Figure 6 (As shown), to accommodate sample tubes 20 of different heights.

[0055] like Figure 4 and Figure 5 As shown, the cover fixing part 2 includes a front stop part 21 and a rear stop part 22. Both the front stop part 21 and the rear stop part 22 are connected to the top of the adapter body 1 and are radially spaced along the adapter body 1. The front stop part 21 has a slot 23 configured to accommodate the connecting part 203. The cover 201 is located between the front stop part 21 and the rear stop part 22. Figure 6 As shown, specifically, the cover body 202 is located between the front stop portion 21 and the rear stop portion 22.

[0056] Preferably, the width of the slot 23 is greater than the width of the connecting part 203, so as to facilitate the insertion of the connecting part 203 into the slot 23.

[0057] By providing a front stop 21 and a rear stop 22 at radial intervals along the adapter body 1, the cover 201 can be clamped between the front stop 21 and the rear stop 22, thereby fixing the cover 201, preventing the cover 201 from rotating at will, and ensuring that the cover 201 avoids the opening of the sample tube 20.

[0058] Preferably, the distance between the front stop 21 and the rear stop 22 is greater than the thickness of the cover body 202, so as to facilitate the insertion of the cover body 202 between the front stop 21 and the rear stop 22.

[0059] When the sample tube 20 is inserted into the adapter body 1, the cover 201 is opened and the tube body 204 of the sample tube 20 is inserted into the adapter body 1. As the tube body 204 is inserted downward, the connecting part 203 is inserted into the slot 23, and the cover body 202 is located between the front stop part 21 and the rear stop part 22.

[0060] like Figure 5 and combined Figure 6 Preferably, the sides of the front stop 21 and the rear stop 22 that are close to each other are both vertical surfaces 24, that is, the side of the front stop 21 facing the cover body 202 and the side of the rear stop 22 facing the cover body 202 are both vertical surfaces 24, so as to ensure that the cover body 202 is vertically set when the cover body 202 is opened, thereby reducing the space occupied by the cover 201 and facilitating the miniaturization of the instrument.

[0061] like Figure 6 and Figure 7 As shown, the height of the front stop 21 is greater than the height of the rear stop 22. The front stop 21 is positioned inside the stop cover body 202, and the rear stop 22 is positioned outside the stop cover body 202. It can be understood that "inner side" refers to the side of the cover 201 facing the tube body 204 when the cover 201 is placed on the tube body 204; the side opposite to the inner side is the outer side.

[0062] Because the rear stop 22 is relatively low, it will not stop the cover body 202 before the sample tube 20 is inserted into place, thus not affecting the insertion of the tube body 204. The front stop 21 is relatively high compared to the rear stop 22, which can effectively stop the cover body 202 and prevent it from rotating toward the opening of the tube body 204.

[0063] like Figure 4 As shown, the front stop 21 includes a first baffle 211 and a second baffle 212 spaced apart, with a slot 23 formed between the first baffle 211 and the second baffle 212. The front stop 21 has a simple structure and is easy to manufacture.

[0064] Furthermore, the first baffle 211 and the second baffle 212 are spaced apart in a direction perpendicular to the radial direction, so that both the first baffle 211 and the second baffle 212 can stop the cover body 202.

[0065] A clearance notch 213 is provided at the upper end of the first baffle 211 and the side of the second baffle 212 that are close to each other, so as to avoid the sealing part 205.

[0066] Optionally, the clearance gap 213 can be an arc-shaped gap.

[0067] The diameter of the circumference of the clearance notch 213 is smaller than the diameter of the circumference of the outer circumference of the cover body 202, so that it will not affect the first baffle 211 and the second baffle 212 from stopping the cover body 202.

[0068] like Figure 4 and Figure 5 As shown, the cover fixing part 2 also includes a connecting block 25. The front stop part 21 and the rear stop part 22 are connected by the connecting block 25 to improve the strength of the front stop part 21 and the rear stop part 22 and prevent the front stop part 21 and the rear stop part 22 from tilting or deforming.

[0069] For example, a connecting block 25 is connected to the side of the first baffle 211 near the rear stop 22, and the connecting block 25 is connected to one end of the rear stop 22. Another connecting block 25 is connected to the side of the second baffle 212 near the rear stop 22, and the connecting block 25 is connected to the other end of the rear stop 22.

[0070] Optionally, the connecting block 25 and the rear stop 22 are integrally formed; or, the front stop 21, the connecting block 25, and the rear stop 22 are integrally formed. Specifically, they can be integrally formed by injection molding.

[0071] like Figure 3 and Figure 4 As shown, the adapter also includes a first positioning rib 3, which is connected to the outer wall of the adapter body 1. The lower end of the first positioning rib 3 is configured to abut against the upper surface 102 of the sample holder 10. The first positioning rib 3 suspends the adapter in the sample slot 101 of the sample holder 10, ensuring that the adapter does not slide downward. Since the sample holder 10 will not be placed upside down, restricting the adapter from moving downward can restrict its vertical movement.

[0072] The adapter can be adapted to sample slots 101 of different diameters, as long as the lower end of the first positioning rib 3 can abut against the upper surface 102 of the sample holder 10. Therefore, the adapter has a wide range of applications and high compatibility.

[0073] There are multiple first positioning ribs 3, which are spaced apart along the circumference of the adapter body 1 to improve the stability of the adapter installation.

[0074] The outer diameter of the adapter body 1 can be smaller than the inner diameter of the sample slot 101, which makes it easier to install and remove the adapter.

[0075] The adapter may also include an extension rib 4, which is connected to the lower end of the first positioning rib 3 and extends along the axial direction of the adapter body 1 to the lower end of the adapter body 1 to improve the strength of the adapter body 1.

[0076] like Figure 3 As shown, the sample holder 10 has a slot 103, which is connected to the sample groove 101. Optionally, the slot 103 extends along the axial direction of the sample groove 101.

[0077] like Figure 3 and Figure 4 As shown, the adapter also includes two second positioning ribs 5, which are respectively connected to the outer wall of the adapter body 1 and are spaced apart along the circumference of the adapter body 1. The side of the two second positioning ribs 5 that is far apart from each other is configured to abut against the groove wall of the groove 103.

[0078] When the adapter is inserted into the sample holder 10, the two second positioning ribs 5 have a guiding function, enabling the adapter to be quickly and accurately inserted into the sample slot 101 of the sample holder 10; the two second positioning ribs 5 also have a fixing function, with the side of the two second positioning ribs 5 that is far apart from each other being configured to abut against the slot wall of the slot opening 103, thereby restricting the adapter from rotating relative to the sample slot 101.

[0079] Although the present invention has been described in detail above with general descriptions, specific embodiments, and experiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
