Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an eight-tube bracket. Background Art

[0002] NGS sequencing (next generation sequencing technology) usually starts with the preparation of DNA libraries. During the library preparation process, DNA fragments usually need to be amplified by PCR (polymerase chain reaction) to make the library reach the concentration required for the machine. The fully automatic gene sequencing library preparation instrument currently used can accurately place the 24-well fluorometer stand on the workbench through a robotic arm, put the three groups of eight-tubes containing the samples to be tested into the fluorometer stand, cover them with a sealing cover, and then start library preparation and concentration determination.

[0003] In the prior art, during the library preparation process, the pipette tip needs to be inserted into the eight-tube strip to add reagents. However, since the fluorometer stand does not have a structure to fix the eight-tube strip, after adding the reagents, when the pipette tip is lifted out of the eight-tube strip, the eight-tube strip is often lifted up together, causing the eight-tube strip to deviate from its original position or even fall out of the fluorometer stand, affecting the subsequent library concentration interpretation.

[0004] Therefore, an eight-tube bracket is urgently needed to solve the above problems. Utility Model Content

[0005] Based on the above, the purpose of the utility model is to provide an eight-tube bracket, which can effectively fix the eight-tube bracket to the bracket body and improve the reliability of placing the eight-tube bracket in the bracket body.

[0009] The fixing assembly includes two deformable parts, both of which are arranged on the bracket body and respectively arranged on both sides of the placement position. When the eight-tube joint is placed or removed from the placement position, the connecting arm can squeeze the two deformable parts to produce deformation. When the eight-tube joint is placed in the placement hole, the two deformable parts can at least restore part of the deformation.

[0010] As a preferred solution of the eight-tube bracket, the deformable member is configured as a rubber ring, and the distance between the two rubber rings located on both sides of the connecting arm is smaller than the width of the connecting arm.

[0011] As a preferred solution of the eight-tube bracket, the outer wall of the rubber ring is configured to be arc-shaped.

[0012] As a preferred solution of the eight-tube bracket, when the tube body is placed in the placement hole, the distance between the upper surface of the connecting arm and the bracket body is h1, and the distance between the lower surface of the deformable part and the bracket body is h2, h1=h2.

[0013] As a preferred solution of the eight-tube bracket, the fixing assembly also includes a bolt, a threaded hole is provided on the bracket body, and a mounting hole is provided on the deformable member. The bolt can be passed through the mounting hole and threadedly connected with the threaded hole.

[0014] As a preferred solution of the eight-tube bracket, one group of the placement positions is provided with two fixing components, and the two fixing components are arranged at intervals along the arrangement direction of the eight placement holes.

[0031] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0032] like Figure 1As shown, this embodiment provides an eight-tube bracket for placing an eight-tube bracket 1, the eight-tube bracket 1 includes eight tube bodies 11, and adjacent tube bodies 11 are connected by a connecting arm 12. The eight-tube bracket includes a bracket body 100 and a fixing assembly 200. At least one group of placement positions is provided on the bracket body 100, and a group of placement positions includes eight placement holes arranged at intervals, and the eight tube bodies 11 can be placed in the placement holes respectively; the fixing assembly 200 includes two deformable members 210, and the two deformable members 210 are both arranged on the bracket body 100 and are respectively arranged on both sides of the placement positions. When the eight-tube bracket 1 is placed or removed from the placement position, the connecting arm 12 can squeeze the two deformable members 210 to generate deformation. When the eight-tube bracket 1 is placed in the placement hole, the two deformable members 210 can at least restore part of the deformation.

[0033] A placement position with eight placement holes is provided on the support body 100 for placing the tube body 11 of the eight-tube strip 1; a fixing assembly 200 is provided for fixing the eight-tube strip 1 to the support body 100, so that the eight-tube strip 1 will not easily deviate or detach from the support body 100 even if it receives an upward force, and further, after adding reagents to the eight-tube strip 1, the eight-tube strip 1 will not be taken away from the support body 100 by the pipette tip that leaves, thereby ensuring that the eight-tube strip 1 can always be located at the same position of the support body 100, thereby improving the firmness and reliability of the connection between the eight-tube strip 1 and the support body 100. Specifically, the fixing assembly 200 includes two deformable members 210, which are provided on the support body 100 and are correspondingly provided on both sides of the connecting arm 12. When placing and removing the eight-tube strip 1, the connecting arm 12 can squeeze the deformable part 210, causing the deformable part 210 to deform, so that the tube body 11 of the eight-tube strip 1 enters or escapes from the placement hole; when the tube body 11 of the eight-tube strip 1 is stably placed in the placement hole, the deformable part 210 can at least restore part of the deformation, so that at least part of the deformable part 210 of the connecting arm 12 is squeezed, so that the eight-tube strip 1 as a whole can be stably placed on the bracket body 100, while ensuring the accuracy of subsequent operations.

[0034] Specifically, when the tube body 11 is placed in the placement hole, the distance between the upper surface of the connecting arm 12 and the bracket body 100 is h1, and the distance between the lower surface of the deformable member 210 and the bracket body 100 is h2, and h1=h2. By configuring in this way, when the tube body 11 is placed in the placement hole, the deformable member 210 can completely restore its deformation and fit with the upper surface of the connecting arm 12. When the eight-link tube 1 is subjected to an upward force, the connecting arm 12 can be restricted from slipping out from between the two deformable members 210. This ensures the stable placement of the eight-link tube 1 on the bracket body 100 while reducing the failure caused by long-term deformation of the deformable member 210, thereby improving the reliability of the fixing assembly 200.

[0035] Optionally, the deformable member 210 is configured as a rubber ring, and the distance between the two rubber rings on both sides of the connecting arm 12 is smaller than the width of the connecting arm 12, so that the connecting arm 12 can squeeze the rubber ring to deform when passing between the two rubber rings, and restore the deformation when the eight-tube 1 is stably placed in the placement hole, and at least partially squeeze the connecting arm 12 to prevent the eight-tube 1 from deviating or even falling out of the placement hole. Alternatively, in other embodiments, the deformable member 210 can also be configured as a deformation block, or other suitable shapes, which are not specifically limited here. By configuring the deformable member 210 to be made of rubber material, it has better elastic recovery force, thereby making the fixation of the eight-tube 1 more reliable; at the same time, the rubber material can be repeatedly deformed and restored, and has a longer service life.

[0036] Furthermore, the fixing assembly 200 also includes a bolt 220, a threaded hole is provided on the bracket body 100, and a mounting hole is provided on the deformable member 210, and the bolt 220 can be inserted into the mounting hole and threadedly connected with the threaded hole. That is, the deformable member 210 is detachably connected to the bracket body 100, which is convenient for replacement when the deformable member 210 is aged or deformed too much and cannot be restored. At the same time, replacement is more convenient, and subsequent maintenance is more time-saving and labor-saving. It can be understood that the through hole of the rubber ring is used as a mounting hole for the insertion of the bolt 220. Exemplarily, the deformable member 210 is configured as an O-ring to reduce the mold opening cost. Optionally, an O-ring with an outer diameter of 5.5 mm and a wire diameter of 1.5 mm is used, and the bolt 220 uses the M2 model to better adapt to the connecting arm 12 of the eight-tube 1.

[0037] Preferably, the outer wall of the rubber ring is arranged to be arc-shaped. With such arrangement, the contact between the rubber ring and the connecting arm 12 can provide guidance when placing and removing the eight-tube strip 1, while not excessively hindering the normal placement and removal of the eight-tube strip 1 on the bracket body 100.

[0038] In this embodiment, one set of placement positions is provided with two fixing assemblies 200, and the two fixing assemblies 200 are arranged at intervals along the arrangement direction of the eight placement holes. By providing two fixing assemblies 200, the reliability of fixing the eight-tube connection 1 is improved.

[0039] Exemplarily, one of the fixing components 200 is disposed between the second placement hole and the third placement hole, and the other fixing component 200 is disposed between the sixth placement hole and the seventh placement hole. By fixing the two ends of the eight-tube strip 1, the force on the eight-tube strip 1 is made more uniform. No matter which tube body 11 the suction head operates on, the entire eight-tube strip 1 will not be displaced in the placement position when it leaves, thereby ensuring the placement reliability of the eight-tube strip 1 in the placement position. In other embodiments, three, four or five fixing components 200 can be provided for each group of placement positions, and the setting position of each fixing component 200 can be set according to actual needs, which is not specifically limited here.

[0040] Furthermore, three groups of placement positions are provided on the support body 100. By providing three groups of placement positions, the support body 100 can simultaneously place three eight-tube strips 1, thereby improving the carrying capacity of the eight-tube strip support. Exemplarily, the three groups of placement positions are arranged side by side, making the arrangement of the eight-tube strips 1 more compact, and making it easier to add reagents and conduct tests on the eight-tube strips 1 later.

[0041] Preferably, adjacent placement positions share a deformable member 210, which can simplify the structure of the eight-tube bracket while ensuring the fixation of the connecting arm 12. That is, three placement positions are arranged side by side on the bracket body 100, with a total of twenty-four placement holes for placing three eight-tubes 1; at the same time, eight deformable members 210 are arranged on the bracket body 100, of which four deformable members 210 on the same side of the placement positions at the edge are only used to fix one connecting arm 12, and the remaining six deformable members 210 are used to fix the connecting arms 12 of two adjacent eight-tubes 1.

[0042] In this embodiment, lugs 110 are provided on both sides of the bracket body 100, and the deformable member 210 on the same side as the placement position at the edge is at least partially located on the lugs 110. By providing the lugs 110, the deformable member 210 on the same side as the placement position at the edge is provided, which can effectively reduce the area of ​​the bracket body 100, thereby reducing the overall size of the eight-tube bracket.

[0043] The use process of the above-mentioned eight-tube bracket is as follows: when placing the eight-tube bracket 1, align the tube body 11 with the placement hole and press down hard. The deformable member 210 is deformed under the pressure of the connecting arm 12. When the tube bodies 11 are placed in the placement holes, the deformable member 210 at least partially restores its deformation and partially squeezes the connecting arm 12 at the same time, so that the eight-tube bracket 1 is stably placed in the placement position for the subsequent addition of reagents and detection into the tube body 11. When taking out the eight-tube bracket 1, an upward force is applied to the lower part of the tube body 11 so that the connecting arm 12 can squeeze the deformable member 210 again to facilitate the eight-tube bracket 1 to be separated from the bracket body 100. When the tube body 11 is separated from the placement hole, the deformable member 210 can restore its deformation again to fix the eight-tube bracket 1 placed in the bracket body 100 next time.

[0044] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
