Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of rollers, in particular to a roller homogenizing device. Background Art
[0002] In medical blood testing, various types of vacuum blood collection tubes generally need to be mixed on a roller homogenizer after blood collection is completed. This ensures that the blood and the reagents reserved in the tube are evenly mixed, fully utilizing the effectiveness of the reagents and promoting various chemical reactions.
[0003] Existing roller homogenizing equipment mainly adopts the form of rotating rollers that swing simultaneously to rotate and swing the blood collection tube placed on the top. The rotation is to mix the materials in the radial direction of the tube, while the swinging is to accelerate the mixing of the materials in the axial direction of the tube. However, in fact, the swinging amplitude of this mixer is very limited, and the axial length of the blood collection tube is usually much larger than the radial dimension. This results in the situation that when the rotation promotes the completion of radial mixing, the swinging promotes the completion of axial mixing, thereby reducing the mixing efficiency. Therefore, it is necessary to develop a new roller mixing device to address the shortcomings of the existing technology. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a roller homogenizing device, comprising an operating base and a fixed disk, a folding bracket being connected between the operating base and the fixed disk, a cavity being opened on the front side of the fixed disk, a driving motor being fixedly installed on the middle part of the cavity, a rotating disk located inside the cavity being sleeved around the driving motor, a plurality of pairs of elastic clips located inside the cavity and evenly distributed are fixedly installed on the front side of the rotating disk, a blood collection tube is sleeved inside each pair of elastic clips, a linkage cover is sleeved on the front side of the driving motor, the front side of the driving motor output shaft is fixedly connected to the front end of the inner cavity of the linkage cover, the rear end of the linkage cover is fixedly connected to the rotating disk, and the front end of the inner cavity of the fixed disk is movably sleeved with a limiting component located in front of the rotating disk.

[0013] 1. Due to the setting of the fixed disk, the axes of several blood collection tubes can be placed in the same vertical plane under the cooperation of the rotating disk and the elastic buckle.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0026] like Figures 1 to 5As shown, the utility model provides a roller homogenizing device, including an operating base 1 and a fixed disk 2, a folding bracket 8 is connected between the operating base 1 and the fixed disk 2, a cavity is opened on the front of the fixed disk 2, a driving motor 3 is fixedly installed in the middle of the cavity, a rotating disk 4 located inside the cavity is sleeved around the driving motor 3, a plurality of pairs of elastic clips 5 located inside the cavity and evenly distributed are fixedly installed on the front of the rotating disk 4, a blood collection tube 6 is sleeved inside each pair of elastic clips 5, a linkage cover 9 is sleeved on the front of the driving motor 3, the front of the output shaft of the driving motor 3 is fixedly connected to the front end of the inner cavity of the linkage cover 9, and the linkage cover 9 is fixedly mounted on the front of the driving motor 3. The rear end is fixedly connected to the rotating disk 4, and the front end of the inner cavity of the fixed disk 2 is movably sleeved with a limit assembly 7 located in front of the rotating disk 4; due to the arrangement of the fixed disk 2, with the cooperation of the rotating disk 4 and the elastic buckle 5, the axes of the several blood collection tubes 6 can be placed in the same vertical plane, and then when the fixed disk 2 rotates, the mixture inside the several blood collection tubes 6 can move axially to provide mixing efficiency; and the blood collection tubes 6 are placed inside the fixed disk 2 through the elastic buckle 5, so that during the mixing period, the several blood collection tubes 6 can be effectively protected by the fixed disk 2 to a certain extent, thereby preventing external moving objects from colliding with the blood collection tubes 6.
[0027] The blood collection tube 6 includes a tube body 61 sleeved inside the elastic buckle 5, and a tube cap 62 is sealed on the outer surface of the tube body 61 at one end away from the driving motor 3, and the front and rear sides of the tube cap 62 are in contact with the limit assembly 7.
[0028] Among them, the inner wall of the elastic buckle 5 and the outer surface of the blood collection tube 6 are both smooth, and the outer surface of the tube cap 62 is rough; due to the setting of the tube cap 62, it can not only be used to encapsulate the substances inside the tube body 61, but also can generate good friction between it and the fixed limiting ring 72, ensuring that the tube cap 62 and the tube body 61 can continue to rotate as a whole under the action of this friction when the blood collection tube 6 revolves.
[0029] Among them, the inner diameter size of the elastic clip 5 close to the rotating disk 4 is larger than the outer diameter size of the tube body 61, and the inner diameter size of the elastic clip 5 away from the rotating disk 4 is smaller than the outer diameter size of the tube body 61; due to the setting of the elastic clip 5, the tube body 61 of different diameter sizes can be clamped under the action of its elastic force, effectively improving the applicable range of mixing.
[0030] The locking cam 72 is fixed to the front of the rotating disk 4, and the front of the locking cam 73 is in contact with the back of the tube cap 62.
[0031] Among them, the front face of the adjustable limiting ring 73 is located behind the back face of the inner cavity of the elastic buckle 5, and the distance between the front face of the adjustable limiting ring 73 and the back face of the inner cavity of the elastic buckle 5 is smaller than the wall thickness of the tube cap 62, that is, when the back face of the tube cap 62 contacts the front face of the adjustable limiting ring 73, the outer surface of the tube body 61 does not contact the back face of the inner cavity of the elastic buckle 5; due to the setting of the adjustable limiting ring 73, it can not only clamp the tube cap 62 with the cooperation of the adjusting ring 71 so that it rolls and rotates under the friction with the fixed limiting ring 72; it can also limit the position of the back face of the tube cap 62, ensuring that the tube bodies 61 of different sizes will never contact the inner wall of the elastic buckle 5, thereby ensuring that the blood collection tube 6 rotates without frequent friction with the elastic buckle 5.
[0032] Among them, the folding bracket 8 includes an outer bracket 81 hinged to the top rear end of the operating base 1, the upper end of the outer bracket 81 is hinged to a first connecting block 82, the upper end of the first connecting block 82 is hinged to an inner bracket 83, the upper end of the inner bracket 83 is hinged to a second connecting block 84, and the second connecting block 84 is fixedly connected to the back of the fixed disk 2. The outer bracket 81, the first connecting block 82, the inner bracket 83 and the second connecting block 84 have good friction with each other. Due to the setting of the folding bracket 8, the fixed disk 2 can be supported to reach a vertical state with the cooperation of the operating base 1, so that the internal mixture of the several blood collection tubes 6 can be mixed axially when the blood collection tubes 6 revolve. After folding the folding bracket 8, the fixed disk 2 can be parallel to the top of the operating base 1, which greatly facilitates carrying.
[0033] The working principle and use process of this utility model:
[0034] As shown in the figure, the folding bracket 8 is unfolded to make the fixed disk 2 reach a vertical state. Then, by operating the base 1 to start the drive motor 3, the rotating disk 4 can be driven to rotate through the linkage cover 9. Since the rotation of the rotating disk 4 can drive the multiple elastic buckles 5 on the front side and the blood collection tube 6 clamped inside to rotate around the axis of the fixed disk 2, the mixture in the tube body 61 can be mixed along the axial direction, which greatly improves the mixing rate.
[0035] When the blood collection tube 6 revolves around the axis of the fixed disk 2 following the rotating disk 4 and the elastic buckle 5, the back of the tube cap 62 at its outer end is supported by the adjustable limiting ring 73, and its front face is tightly fitted with the back face of the fixed limiting ring 72. Therefore, when the blood collection tube 6 revolves, the tube cap 62 rotates, which in turn drives the tube body 61 to rotate, thereby mixing the mixture inside in the radial direction.
[0036] During mixing and use, since the blood collection tubes 6 are placed vertically on the inner side of the fixed plate 2, they will not be accidentally damaged by external objects, which greatly protects the integrity of the blood collection tubes 6;
[0037] After use, the folding bracket 8 can be folded to fix the disk 2 so that it can be flattened on the top of the operating base 1, which is convenient for carrying.
