[0035] In order to make the purpose, technical solutions and advantages of the utility model clearer and more definite, the following further describes the utility model in detail with reference to the accompanying drawings and by way of examples. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.

[0036] Please refer to Figures 1 - 3 at the same time. The utility model provides some preferred embodiments of a crushing and shaking device. The crushing and shaking device is used to crush and shake biological indicators. It can be understood that for existing products of biological indicators, by pressing down the bottle cap, the internal ampoule glass bottle moves downward and is squeezed into the ampoule crusher. Since the diameter of the ampoule crusher gradually decreases, the ampoule glass bottle breaks during the process of pressing down the ampoule glass bottle, and the culture solution flows out and mixes with the bacterial tablets on the bottle body.

[0037] Such as Figures 1 to 3As shown, the crushing and shaking device includes a base 1, a bracket 4, a shaking assembly, and a crushing assembly. The base 1 has an upwardly open cavity 101. The base 1 can be of any shape such as cylindrical or cuboid. The cavity 101 is cylindrical. The top of the base 1 has an opening that communicates with the cavity 101. The bracket 4 is provided on the two side walls of the base 1 so that the front and rear ends of the base 1 have open spaces for easy use by medical staff. The bracket 4 is used to support the crushing assembly. The shaking assembly includes a turntable 2 and a power component. The turntable 2 is rotatably provided on the base 1. A number of indicator grooves 201 are provided on the turntable 2. Thus, multiple biological indicators 3 can be placed at one time. It can be understood that the number of indicator grooves 201 is at least two and matches the shape of the existing biological indicator 3. The depth of the indicator groove 201 should be at least greater than half of the height of the biological indicator 3 to prevent the biological indicator 3 from easily detaching from the indicator groove 201. The power component is provided in the cavity 101 and is connected to the turntable 2 to drive the turntable 2 to rotate forward and backward on the base 1 to drive the turntable 2 to produce a shaking effect, so that the biological indicators 3 can be fully mixed after being crushed. The crushing assembly is provided on the bracket 4 and is used to abut against the turntable 2 to press a number of the indicator grooves 201.

[0038] In the above embodiment, the turntable 2 can be made of a transparent material so that medical staff can easily view the mixing state and color of the biological indicator 3 in the indicator groove 201 of the turntable 2. The indicator grooves 201 of the turntable 2 are provided with three layers and are arranged in an array along the circumference of the turntable 2 to facilitate placing more biological indicators 3. In the actual use process, medical staff first place the biological indicators 3 to be used into the biological indicator grooves 201, then use the crushing assembly to crush a number of the biological indicators 3 placed in the indicator grooves 201 on the turntable 2 first, and then drive the turntable 2 to rotate forward and backward on the base 1 through the power component to produce a shaking effect, so that the culture medium is fully mixed. Finally, the biological indicator 3 is placed on the biological reader to read the value. In this embodiment, the two operation steps of shaking and crushing the biological indicator 3 are combined, and multiple biological indicators 3 can be crushed at one time, improving the work efficiency of medical staff.

[0039] See Figure 2 As shown, in a preferred embodiment of the present utility model, the power component includes a motor 7 and a timing reverse control circuit board. The motor 7 is provided in the base 1. The output shaft of the motor 7 is fixedly connected to the turntable 2. The timing reverse control circuit board is provided in the base 1 and is connected to the motor 7 through a wire.

[0040] Specifically, the motor 7 is installed in the middle of the base 1. A sleeve is provided at the bottom of the turntable 2, and the sleeve is fixedly connected to the output shaft of the motor 7 through bolts. A part of the turntable 2 abuts against the base 1 to reduce the rotational pressure on the output shaft of the motor 7. The timing reverse control circuit board means controlling the motor 7 to automatically switch between forward and reverse rotations within a certain period of time, so that the biological indicator 3 in the turntable 2 produces a shaking effect, and further can make the crushed biological indicator 3 mix more evenly. It should be noted that to achieve the forward and reverse rotations of the motor 7, only need to swap any two of the three-phase power supply inlets of the motor 7 to achieve the forward and reverse rotations of the motor 7. The forward and reverse rotations of the motor 7 are widely used, such as in equipment like lathes and bench drills. The timing of the timing reverse is a preset value, for example, within 2s - 10s, the output shaft of the motor 7 is switched from forward rotation to reverse rotation. It can be understood that the motor 7 uses a reduction motor 7, and the rotational speed of the reduction motor 7 is slower to prevent the biological indicator 3 from being thrown out due to the too fast rotation of the turntable 2.

[0041] See Figure 2 As shown, in a preferred embodiment of the present invention, the crushing assembly includes a lifting member and a pressing plate 6. The lifting member is arranged on the bracket 4, and the pressing plate 6 is connected to the lifting member for pressing a plurality of the indicator grooves 201. By driving the pressing plate 6 through the lifting member, the pressing plate 6 descends and presses against the biological indicator 3 on the turntable 2, so that the ampoule bottle in the biological indicator 3 is broken and the culture solution flows out. There are various ways to implement the lifting member. For example, the pressing plate 6 can be lifted and lowered by the rotation of a lead screw, or the pressing plate 6 can be lifted and lowered by a hydraulic rod. Those skilled in the art can select a suitable lifting member according to actual needs.

[0042] Further, see Figure 2 As shown, in a preferred embodiment of the present invention, the lifting member includes an electric telescopic rod 5. The electric telescopic rod 5 is arranged on the bracket 4 and is connected to the pressing plate 6. In this embodiment, the electric telescopic rod 5 is installed in the middle of the top of the bracket 4. The electric telescopic rod 5 drives the pressing plate 6 to descend and press against the biological indicator 3 on the turntable 2, so that the biological indicator 3 is crushed. When not in use, the pressing plate 6 can be located at the bottom of the bracket 4 to reserve space for medical staff to place the biological indicator 3 on the turntable 2. By driving the pressing plate 6 through the electric telescopic rod 5, the structure is simple, easy to implement, and more convenient to use.

[0043] Furthermore, see Figure 2 As shown, the diameter of the pressing plate 6 is greater than or equal to the diameter of the turntable 2. Both the pressing plate 6 and the turntable 2 are cylindrical. By making the diameter of the pressing plate 6 greater than or equal to the diameter of the turntable 2, it is ensured that the pressing plate 6 can press all the biological indicators 3 on the turntable 2.

[0044] See Figure 2As shown, in a preferred embodiment of the present utility model, the bracket 4 includes two connecting parts 401 and a supporting part 402, the two connecting parts 401 are respectively arranged on both sides of the base 1, the connecting parts 401 are bent to form an L shape, and the supporting part 402 is arranged on the two connecting parts 401.

[0045] Specifically, since the turntable 2 rotates on the base 1, in order to ensure that the rotation of the turntable 2 is not affected, the bracket 4 extends outwardly to the two sides of the base 1, thereby bending to form two L-shaped connecting parts 401, and in order to ensure that the biological indicator 3 can be conveniently placed, the two connecting parts 401 are fixedly connected to the supporting part 402, so that the electric telescopic rod 5 and the pressing plate 6 are installed at a certain height. It should be noted that the two connecting parts 401 and the supporting part 402 are integrally formed, thereby increasing the strength of the bracket 4 and extending the service life of the bracket 4.

[0046] Further, see Figure 2 As shown, in a preferred embodiment of the present utility model, a fixing part 403 is provided on each of the two connecting parts 401, and the two fixing parts 403 are respectively fixedly connected to the side wall of the base 1. Specifically, since the contact area between the connecting part 401 and the base 1 is small, by setting the fixing part 403 as a plate-like structure, the fixing part 403 and the connecting part 401 are integrally formed, and the fixing part 403 is used to fit on the side wall of the base 1, and then the fixing part 403 is fixedly connected to the side wall of the base 1 by bolts passing through the fixing part 403, so that the bracket 4 is firmly fixed.

[0047] In a preferred embodiment of the present invention, an elastic gasket is provided in the indicator groove 201, and the elastic gasket is wrapped in the indicator groove 201 and has an annular structure. The elastic gasket is a gasket made of elastic rubber material, and the annular diameter is slightly smaller than the diameter of the biological indicator 3, so that the biological indicator 3 can be embedded in the indicator groove 201 and is not easily thrown out during the rotation of the shaking component.

[0048] See also Figure 2 As shown, in a preferred embodiment of the present invention, a bearing 8 is provided between the turntable 2 and the base 1. Specifically, the bearing 8 is installed at the top opening of the base 1, and a protrusion is provided at the bottom of the turntable 2, which is rotatably connected to the bearing 8, thereby reducing the friction force of the turntable 2 rotating on the base 1.

[0049] See also Figure 2 As shown, in a preferred embodiment of the present utility model, a controller 9 is disposed in the base 1, and the controller 9 is connected to the crushing assembly and the shaking assembly through wires.

[0050] Specifically, a controller 9 is installed inside the base 1. The controller 9 is connected to the motor 7 and the electric telescopic rod 5 through two wires. The wire of the electric telescopic rod 5 can extend into the base 1 along one side of the bracket 4, thus not affecting the normal use of the device. More specifically, two control switches are provided on the outer wall of the base 1. The control switches are connected to the controller 9 through wires. One is used to control the lifting of the electric telescopic rod 5, and the other controls the rotation time of the motor 7, making it more convenient for medical staff to use.

[0051] In summary, the present utility model provides a crushing and shaking device. By setting a base, a bracket, a shaking component and a crushing component, the shaking component includes a turntable and a power component. A number of indicator grooves are provided on the turntable. By combining the two operation steps of crushing and shaking the biological indicator, the device can not only crush the biological indicator to make the culture solution flow out, but also shake the biological indicator to make the culture solution fully mixed. Moreover, multiple biological indicators can be crushed at one time, improving the work efficiency of medical staff.

[0052] It should be understood that the application of the present utility model is not limited to the above examples. For those of ordinary skill in the art, improvements or transformations can be made according to the above description.
