DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with specific implementation methods. The same figure marks in the accompanying drawings represent the same components. It should be noted that the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Compared to the embodiments shown in the drawings, feasible embodiments within the scope of protection of the present invention may have fewer components, other components not shown in the drawings, different components, differently arranged components, or differently connected components, etc. In addition, two or more components in the drawings may be implemented in a single component, or a single component shown in the drawings may be implemented as multiple separate components.

[0036] The embodiment of the present invention discloses an oscillating device, and in particular, an oscillating device suitable for oscillating a blood collection tube 100 .

[0037] like Figure 1 and Figure 2 As shown, Figure 1 is a schematic structural diagram of an exemplary oscillation device disclosed in this embodiment, Figure 2 This is a cross-sectional view of the local structure of the oscillation device. Figure 1 In the oscillation device shown, the oscillation device may include a vortex mixer 10 and a supporting mechanism 20 .

[0038] In this embodiment, combined with Figure 1 and Figure 2 As shown, the vortex mixer 10 has an oscillating disk 11. It is understood that the vortex mixer 10 in this embodiment is an instrument known in the prior art that can output oscillation and vortex motion through the oscillating disk 11, and no further details will be given for the vortex mixer 10.

[0039] In this embodiment, the blood collection tube 100 to be oscillated can be carried on the carrying mechanism 20, and as shown in FIG. Figure 1 As shown, the bottom end of the blood collection tube 100 carried on the supporting mechanism 20 is in contact with the oscillation disk 11 of the vortex mixer 10. In this way, when the vortex mixer 10 works to output oscillation and vortex motion through the oscillation disk 11, the blood and reagents such as anticoagulants inside the blood collection tube 100 in contact with the oscillation disk 11 can be oscillated and mixed.

[0040] It is understood that the blood collection tube 100 described in this embodiment may have the following features: Figure 3 The structure shown in Figure 3The blood collection tube 100 shown may include a tube body 101 for containing blood and reagents such as an anticoagulant, and a detachable tube cap 102 disposed at the opening of the tube body 101. Furthermore, in typical blood collection tubes 100, the outer diameter of the tube cap 102 is larger than the outer diameter of the tube body 101.

[0041] The supporting mechanism 20 for supporting the blood collection tube 100 may be constructed in the following manner but is not limited thereto.

[0042] Combine Figure 1 、 Figure 2 、 Figure 4 or Figure 5 As shown, the supporting mechanism 20 may include a supporting plate 21, which is located above and opposite the oscillating plate 11. The supporting plate 21 is provided with a plurality of supporting channels 211, each corresponding to a blood collection tube 100. The supporting channels 211 extend through the thickness of the supporting plate 21. In actual use, a single blood collection tube 100 can be inserted into a single supporting channel 211. The supporting channels 211 provided on the supporting plate 21 can be evenly distributed. For example, if the supporting plate 21 is generally circular, the supporting channels 211 can be distributed in a circular array to facilitate machining as many supporting channels 211 as possible on a single supporting plate 21.

[0043] Furthermore, the inner diameter of the carrying channel 211 is larger than the outer diameter of the tube body 101 of the blood collection tube 100, and at the same time, the inner diameter of the carrying channel 211 is smaller than the outer diameter of the tube cap 102 of the blood collection tube 100. Figure 2 The through holes shown penetrate both the top and bottom surfaces of the carrier plate 21 .

[0044] Based on the above configuration, when a large number of blood collection tubes 100 need to be oscillated, the blood collection tubes 100 to be oscillated are first inserted into the corresponding carrying channels 211 in sequence with the tube bodies 101 facing downwards, and Figure 2 As shown, the bottom end of the tube body 101 of the blood collection tube 100 inserted into the carrying channel 211 (i.e., the end of the tube body 101 away from the tube cap 102) contacts the oscillating disk 11 of the vortex mixer 10. In particular, for a single carrying channel 211 and its corresponding blood collection tube 100, since the inner diameter of the carrying channel 211 is smaller than the outer diameter of the tube cap 102, the tube cap 102 of the blood collection tube 100 inserted into the carrying channel 211 can be as follows Figure 2The blood collection tube 100 is supported on the carrier disk 21 in the manner shown, thereby temporarily securing the blood collection tube 100. Simultaneously, since the inner diameter of the carrier channel 211 is larger than that of the tube body 101, a gap is formed between the tube body 101 passing through the carrier channel 211 and the inner wall of the carrier channel 211, allowing the tube body 101 to retain a certain degree of freedom. The vortex mixer 10 can then be activated to oscillate the blood collection tube 100. It will be appreciated that since the tube body 101 passing through the carrier channel 211 retains a certain degree of freedom, when the vortex mixer 10 outputs oscillation and vortex motion through the oscillating disk 11, the oscillating disk 11 can drive the blood collection tube 100 to vibrate, causing the blood and reagents such as anticoagulants within the tube body 101 to oscillate and mix.

[0045] It can be seen that the oscillation device disclosed in this embodiment is capable of temporarily fixing the blood collection tube 100 and making the bottom end of the blood collection tube 100 contact with the oscillation disk 11 of the vortex mixer 10 by providing a vortex mixer 10 and a supporting mechanism 20 with a supporting disk 21, and providing a supporting channel 211 corresponding to the blood collection tube 100 on the supporting disk 21. In this way, it is only necessary to start the vortex mixer 10 to achieve batch oscillation of a large number of blood collection tubes 100. Compared with the manual oscillation method, it is more time-saving and labor-saving, and the oscillation effect is also better than manual oscillation.

[0046] Considering that in practice, the blood collection tubes 100 to be oscillated may have various specifications and models, it is known that blood collection tubes 100 of different specifications and models in the prior art often have substantially the same external structure, and the difference may only be the length of the tube body 101 .

[0047] Therefore, this embodiment further improves the structure of the supporting mechanism 20 so that the oscillating device can be used with blood collection tubes 100 of various specifications and models.

[0048] Specifically, this embodiment further provides that the distance between the carrier plate 21 and the oscillating plate 11 is adjustable. It is understood that, in conjunction with the foregoing, when the tube body 101 of the blood collection tube 100 passes through the corresponding carrying channel 211, the tube cap 102 of the blood collection tube 100 will be carried on the carrier plate 21, and the difference between blood collection tubes 100 of different specifications and models is only the length of the tube body 101. Therefore, by setting the distance between the carrier plate 21 and the oscillating plate 11 to be adjustable, when facing blood collection tubes of different specifications and models, it is only necessary to adjust the distance between the carrier plate 21 and the oscillating plate 11 according to the length of the tube body 101 of the blood collection tube 100, so that the tube body 101 of the corresponding specification and model of the blood collection tube 100 can contact the oscillating plate 11 after passing through the corresponding carrying channel 211.

[0049] The distance between the supporting plate 21 and the oscillating plate 11 can be adjusted in the following manner.

[0050] Combine Figure 4 As shown, the carrying mechanism 20 may further include a plurality of carrying adjustment units 22, and the plurality of carrying adjustment units 22 may be sequentially arranged along the circumference of the carrying plate 21. For example, the drawings of this embodiment show a case where two carrying adjustment units 22 are provided, and the two carrying adjustment units 22 are symmetrically distributed along the circumference of the carrying plate 21.

[0051] The load-bearing adjustment unit 22 may include a fixing post 221 and a connector 222. The fixing post 221 is fixed relative to the load-bearing plate 21. For example, the fixing post 221 may be connected to the vortex mixer 10 via a clamping member 226, which will be described below. The fixing post 221 is provided with a plurality of connection locations arranged in a vertical direction. The connector 222 is connected to the load-bearing plate 21 and is adapted to connect to any of the plurality of connection locations on the fixing post 221.

[0052] In this way, when it is necessary to adjust the distance from the supporting plate 21 to the oscillation plate 11, the multiple connection positions on the fixed column 221 are arranged in sequence along the vertical direction. Therefore, it is only necessary to adjust the position of the connecting piece 222 of each supporting adjustment unit 22 connected to the fixed column 221 to achieve the adjustment of the distance from the supporting plate 21 to the oscillation plate 11.

[0053] In order to facilitate connecting the connecting member 222 to one of the connection positions on the fixing column 221, as shown in FIG. Figure 4 As shown, the fixing post 221 is provided with fixing holes 223 corresponding to each connection position. Figure 5 As shown, the connecting member 222 of each load-bearing adjustment unit 22 is provided with a connecting hole 224 that matches the fixing hole 223. When the connecting member 222 needs to be connected to the corresponding connecting position on the fixing column 221, it is only necessary to align the connecting hole 224 on the connecting member 222 with the fixing hole 223 at the corresponding connecting position on the fixing column 221. At this time, the load-bearing adjustment unit 22 may also include a fastener 225, which is suitable for Figure 2 The method shown is to pass through the aligned connection hole 224 and the fixing hole 223 to fix the connecting member 222 to the corresponding connection position of the fixing column 221. For example, the fixing hole 223 can be a threaded hole with an internal thread, and the fastener 225 can be a bolt with a knob. The provision of the knob facilitates the assembly and disassembly of the bolt.

[0054] Among them, reference Figure 4 As shown, the connecting member 222 may be a component that is sleeved on the outer wall of the fixing column 221 , so as to improve the reliability of the connection between the connecting member 222 and the fixing column 221 .

[0055] Further, such as Figure 1 or Figure 2 As shown, the vortex mixer 10 may further include a snap ring 12 disposed around the oscillating disk 11. Figure 4 As shown, each load-bearing and adjusting unit 22 may further include a clamping member 226 provided at the bottom end of the fixing column 221, and the clamping member 226 is provided with a clamping groove 227 suitable for clamping to the clamping ring 12. It can be understood that, through the above arrangement, the entire load-bearing mechanism 20 becomes a detachable component relative to the vortex mixer 10. When the load-bearing mechanism 20 needs to be installed on the vortex mixer 10, it is only necessary to allow the clamping member 226 of each load-bearing and adjusting unit 22 to be clamped with the help of the clamping groove 227 as shown in FIG. Figure 2 The method shown is to snap onto the snap ring 12, which is simple and convenient to operate.

[0056] In this embodiment, combined with Figure 1 and Figure 2 As shown, the carrying mechanism 20 may further include a limiting plate 23. The limiting plate 23 is disposed above the carrying plate 21 and opposite to the carrying plate 21, and the distance between the limiting plate 23 and the carrying plate 21 is adjustable.

[0057] It is understood that by adding the limiting plate 23, after the tube bodies 101 of all the blood collection tubes 100 to be oscillated have passed through the corresponding carrying channels 211 to be temporarily fixed on the carrying plate 21, the distance between the limiting plate 23 and the carrying plate 21 can be adjusted so that a gap is formed between the limiting plate 23 and the tube caps 102 of each blood collection tube 100. Figure 2 As shown, the gap is smaller than the length of the tube body 101 of the blood sampling tube 100. Thus, when the vortex mixer 10 is working, since a gap is formed between the tube cap 102 of each blood sampling tube 100 and the limiting disk 23, each blood sampling tube 100 can be oscillated normally. Moreover, since the gap between the limiting disk 23 and the tube cap 102 of each blood sampling tube 100 is smaller than the length of the tube body 101 of the blood sampling tube 100, the limiting disk 23 can play a good limiting role to prevent the blood sampling tube 100 from escaping from the corresponding carrying channel 211 in the vertical direction, thereby improving the reliability of the blood sampling tube 100 when it is oscillated.

[0058] The distance between the limiting plate 23 and the carrying plate 21 can be adjusted in the following manner but is not limited thereto.

[0059] Combine Figure 4 and Figure 6As shown, the supporting mechanism 20 may further include a plurality of limit adjustment units 24, and the plurality of limit adjustment units 24 may be sequentially arranged along the circumference of the limit plate 23. For example, the drawings of this embodiment show a case where two limit adjustment units 24 are provided, and the two limit adjustment units 24 are symmetrically distributed along the circumference of the limit plate 23.

[0060] The limit adjustment unit 24 includes a limit screw 241, a connecting ring 242, a first limit nut 243 and a second limit nut 244. The limit screw 241 is fixed relative to the limit disk 23. For example, the limit screw 241 of a single limit adjustment unit 24 can be fixed on the connecting piece 222 of a single load-bearing adjustment unit 22. The connecting ring 242 is connected to the limit disk 23, and the connecting ring 242 is provided with a hole for the limit screw 241 to pass through, and the inner diameter of the hole on the connecting ring 242 is smaller than the outer diameter of the first limit nut 243 and the second limit nut 244. The first limit nut 243 and the second limit nut 244 are both threadedly connected to the limit screw 241, and the first limit nut 243 and the second limit nut 244 are respectively located on the upper and lower sides of the connecting ring 242.

[0061] In this way, when the distance between the limiting plate 23 and the carrying plate 21 needs to be adjusted, it is only necessary to adjust the position of the first limiting nut 243 and the second limiting nut 244 of each limiting adjustment unit 24 on the limiting screw 241. During the adjustment process, if the limiting plate 23 needs to be moved downward to approach the carrying plate 21, the second limiting nut 244 of each limiting adjustment unit 24 is first screwed so that the second limiting nut 244 of each limiting adjustment unit 24 moves downward to a suitable position. Then, the limiting plate 23 can be moved downward until the connecting ring 242 of each limiting adjustment unit 24 connected to the limiting plate 23 is supported on the corresponding second limiting nut 244. Then, it is only necessary to screw the first limiting nut 243 of each limiting adjustment unit 24 so that the first limiting nut 243 of each limiting adjustment unit 24 moves downward until it abuts against the corresponding connecting ring 242, thereby limiting the degree of freedom of the connecting ring 242 and locking the position of the limiting plate 23. Correspondingly, the position of the limiting plate 23 can be adjusted upwards in a similar manner as described above, or the limiting plate 23 can be directly removed from the carrying plate 21 .

[0062] It can be understood that by adopting the above method, not only can the distance from the limit plate 23 to the carrying plate 21 be adjusted, but the limit plate 23 can also be removed from the carrying plate 21. In this way, combined with the above, when it is necessary to insert the blood collection tube 100 to be oscillated, the limit plate 23 can be removed first to expose the carrying channel 211 on the carrying plate 21. After all the blood collection tubes 100 are inserted into the corresponding carrying channels 211, the limit plate 23 can be installed to limit each blood collection tube 100.

[0063] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
