[0058] Embodiments of the present application are described in detail below with reference to the attached drawing figures, wherein the same or like reference numerals and characters throughout the figures denote the same or like elements or features. The embodiments described below are exemplary and are intended to be illustrative of the present application and are not to be used to limit the present application.

[0059] In this document, relational terms such as first and second, and the like can be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus.

[0060] As described in the background, the swing or oscillation shaking device in the prior art, although to a certain extent, improves the efficiency of blood mixing, but its structure is complex, the use cost is high. The existing mixing device can realize the mixing of blood through horizontal shaking and / or vertical shaking, but the uniformity of blood mixing is insufficient, which affects the accuracy of the subsequent detection equipment, reduces the overall work efficiency, and the use flexibility of the existing blood shaking device is low. At the same time, this kind of swing or oscillation mixing method may also cause damage to the blood sample. Vigorous shaking or oscillation may cause blood cells to rupture, causing hemolysis. Hemolysis will make the originally clear serum turbid, thereby affecting the accuracy of the detection result. In addition, hemolysis may also cause damage to the components in the blood, further affecting the reliability of the detection result.

[0061] Therefore, in order to solve the above technical problems in the prior art, the present embodiment provides a medical simple shaker, as shown in Figure 1 The blood shaker comprises:

[0062] a base 700;

[0063] a mixing assembly, which is integrally inclinedly arranged on the top of the base;

[0064] As shown in Figure 2 The mixing assembly comprises:

[0065] a connecting seat 300, which is fixedly installed at the bottom of the base 700, and is provided with a power input portion at one side of the connecting seat 300;

[0066] a rotating frame 100, which is rotatably installed with the connecting seat and is driven to rotate by the power input portion, as shown in Figure 4 The rotating frame comprises a rotating disc 120, which is rotatably connected with the connecting seat and is driven to rotate by the power input portion, and a plurality of accommodating grooves 140 for accommodating the bottom of the container are arranged on the surface of the rotating disc, and the accommodating grooves are driven to rotate along the circumferential direction of the rotating disc relative to the rotating disc by the power input portion;

[0067] a fixing portion, which keeps the container and the rotating frame relatively fixed by the fixing portion.

[0068] The present embodiment inserts the bottom of the container (such as a test tube, a sample bottle, a storage cylinder, etc.) containing blood into the accommodating groove on the rotating disc, fixes the container through the fixing portion, and then inputs power through the power input portion to make the rotating disc rotate and the container rotate, thereby realizing the mixing of the blood in the container.

[0069] In this embodiment, the rotating power input unit drives the rotating frame to rotate circumferentially. As the rotating frame rotates, it also drives the container to rotate. This utility model has a simple structure, low manufacturing cost, is suitable for various application scenarios, and has high flexibility of use. The uniform shaking of blood is achieved by the rotation of the container itself and the rotation around the central rod, which improves the efficiency of blood mixing inside the container, improves the uniformity of blood mixing, and avoids damage to blood samples that may be caused by violent shaking.

[0070] In this embodiment, the power input unit can be selected as follows: Figure 2 The handwheel 800 shown can be manually turned to drive the rotation of the turntable and the container, thereby improving the flexibility of the blood shaker and enabling it to be used outdoors, in the field, or in other harsh environments when it is no longer indoors.

[0071] Of course, the power input unit can also be a motor or other device that can automatically drive the turntable and container to rotate.

[0072] For example, such as Figure 3 As shown, a worm gear mechanism 320 can be installed in the connecting seat. The worm in the worm gear mechanism is connected to the power input part, and the worm wheel in the worm gear mechanism is connected to the rotating shaft 170 of the rotating frame.

[0073] like Figure 9 As shown, an internal gear 310 is fixedly installed inside the connecting seat, such as... Figure 5 As shown, an external gear 150 is installed at the bottom of the receiving groove, and the external gear meshes with the internal gear.

[0074] like Figure 10 As shown, when the turntable rotates, the internal gear rotates along with the turntable around the turntable's axis. Since the internal gear meshes with the external gear and the external gear is relatively fixed, the internal gear also rotates when the turntable rotates, thereby driving the receiving groove to rotate.

[0075] Example 2:

[0076] Based on Embodiment 1, this embodiment provides a structural scheme for the fixing part, such as... Figure 5 As shown, the rotating frame further includes:

[0077] A center rod 180 is provided, which is perpendicular to the surface of the rotating disk, and one end of the center rod is connected to the center position of the surface of the rotating disk;

[0078] Connecting rod 160, the connecting rod is arranged radially along the central rod and is fixedly connected to the central rod. The connecting rod is provided in an array, distributed circumferentially along the central rod, and each array of the connecting rods corresponds to the receiving groove.

[0079] like Figure 8As shown, the fixing part is a holder 500, which comprises:

[0080] A fixed clamping plate 520 is fixedly connected with the end of the connecting rod, and has a first clamping part in the shape of a circular arc at the end away from the connecting rod;

[0081] An active clamping plate 510 is pivotally connected with the end of the fixed clamping plate close to the connecting rod, and the fixed clamping plate and the active clamping plate are further connected through a second elastic member 530, and the active clamping plate has a second clamping part in the shape of a circular arc at the end away from the connecting rod;

[0082] The first clamping part and the second clamping part are oppositely arranged, and form a clamping ring in partial contact with the outer side surface of the container.

[0083] In this scheme, the active clamping plate is manually pried apart to be separated from the fixed clamping plate, the side part of the container is inserted between the first clamping part of the fixed clamping plate and the second clamping part of the active clamping plate, then the bottom part of the container is inserted into the accommodating groove, the active clamping plate is released and rotated under the action of the second elastic member, so that the inner side surfaces of the first clamping part and the second clamping part are in partial contact with the outer side surface of the container, and the clamping and fixing of the container are realized.

[0084] In addition, a rotating structure 540 can also be arranged on the inner side surfaces of the first clamping part and the second clamping part.

[0085] The material of the rotating structure includes but is not limited to soft materials such as rubber, sponge and foam.

[0086] By arranging the rotating structure on the inner side surfaces of the first and second clamping parts, the rotation of the container can be reduced, the clamping stability of the container can be improved, and the excessive friction between the clamping ring and the container can be avoided to cause the container to be difficult to rotate.

[0087] For example, as shown in Figure 13 The rotating structure 540 comprises:

[0088] An arc-shaped plate 541 is fixedly installed on the inner side surfaces of the first clamping part and the second clamping part;

[0089] A rolling ball 542 is rollingly installed on the inner side surface of the arc-shaped plate.

[0090] The rolling ball can also be replaced by a roller.

[0091] Embodiment 3:

[0092] Based on Embodiment 1, another structure scheme of the fixing part is provided in this embodiment, as shown in Figure 11As shown, unlike Embodiment 2, this embodiment no longer sets a connecting rod and a clamp on the central rod, but sets a rubber ring 141 in the upper part of the receiving groove, and the rubber ring and the receiving groove remain relatively fixed.

[0093] In this embodiment, the bottom of the container is forcefully inserted into the receiving groove. After insertion, the side of the bottom of the container will compress the rubber ring, deforming it. The rubber ring's own recovery action will resist the deformation, thus allowing the rubber ring to clamp the container tightly in the receiving groove, thereby fixing the container.

[0094] Example 4:

[0095] The fixing part described in Embodiment 2 has the following drawback: during rotation, the container may move linearly along the axis of the clamping ring, causing the container to detach from the rotating frame.

[0096] Therefore, in order to solve this technical problem, this embodiment proposes improvements based on embodiment 2, such as... Figure 2 As shown, the blood shaker also includes a pressure plate 200, which is slidably connected to the central rod. An adjusting nut 600 threadedly connected to the central rod is also provided on the central rod. The adjusting nut is located on the side of the pressure plate away from the rotating plate.

[0097] like Figure 6 As shown, the pressure plate includes:

[0098] Slide 200, which is slidably connected to the center rod;

[0099] A pressure plug 210, which is disposed corresponding to a receiving groove and is rotatably mounted on a slide, has a groove defining the top of the receiving container.

[0100] For example, such as Figure 7 As shown, a flexible pad 220 is provided in the groove.

[0101] For example, a guide rod 130 parallel to the center rod is fixed on the surface of the rotating disk away from the connecting seat, and a first elastic element 400 is sleeved on the guide rod. The first elastic element is disposed between the sliding disk and the rotating disk.

[0102] In this embodiment, by rotating the adjusting nut, the pressure plate is squeezed closer to the top of the container until the top of the container is accommodated in the groove. The groove limits the top of the container, thereby improving the stability of the container. The flexible pad protects the top of the container and prevents it from being squeezed and damaged. When the nut is loosened, the pressure plate returns to its original position under the action of the first elastic element, thereby realizing the separation of the pressure plate from the container.

[0103] In the utility model, the embodiment 2 and 3 can be used in combination, and the embodiment 4 can also be applied to the embodiment 3.

[0104] The above description of disclosed embodiments enables those skilled in the art to carry out or use the utility model. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the utility model. Therefore, the utility model will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
