[0026] The embodiment of the utility model provides a biomedical mixing device, which can filter residues and particulate matter through a filter plate, thereby solving the problem that it is difficult to filter residues and undissolved particulate matter generated during mixing in the above-mentioned technology.

[0027] See also Figure 2 The stirring roller 2 is connected to the stirring box 1 for rotation. The stirring roller 2 is connected to the output shaft of the motor. The motor is a prior art and will not be described in detail in this application. When the motor is started, the stirring roller 2 can be driven to rotate.

[0028] The inner wall of the mixing box 1 is slidably connected with a filter 3, and the mixing roller 2 is rotatably connected to the filter 3. When the filter 3 vibrates up and down, it can slide on the surface of the mixing roller 2 without causing any influence on the rotation of the mixing roller 2. A drop hole is provided at the bottom end of the filter 3, which can allow the screened residue and particulate matter to fall into the collection box 5 through the drop hole.

[0029] The inner wall of the mixing box 1 is fixedly connected with a stabilizing rod 4, and the mixing roller 2 is rotatably connected to the stabilizing rod 4. The stabilizing rod 4 provides support for the rotation of the mixing roller 2, thereby increasing the stability of the device.

[0030] See also Figure 1 and Figure 2 The interior of the mixing box 1 is slidably connected to a collecting box 5, and the width of the collecting box 5 is slightly larger than the width of the dropping hole opened on the surface of the filter screen 3. Even if the filter screen 3 vibrates, it does not affect the filtered residues and particulate matter from falling into the interior of the collecting box 5. The staff can pull the collecting box 5 out of the mixing box 1 to clean it.

[0031] See also Figure 3 Two pulleys are fixedly connected to the outer surface of the stirring roller 2, and the two pulleys are respectively connected to the pulleys fixed on the surface of two rotating rods 801 through belts. The rotation of the stirring roller 2 can drive the rotating rod 801 to rotate, thereby providing power support for the vibration filtration of the filter 3.

[0032] See also Figure 2 and Figure 3 The outer surface of the stirring roller 2 is fixedly connected to a linear array of sleeves 6, and the outer surface of each sleeve 6 is fixedly connected to a circular array of stirring rods 7. The rotation of the stirring roller 2 drives the sleeve 6 to rotate, and the sleeve 6 drives the stirring rod 7 to rotate, thereby stirring the mixed liquid inside the device and improving the mixing effect of the device.

[0033] See also Figure 1 The bottom surface of the mixing box 1 is fixedly connected to a discharge pipe 9, and a valve 10 is installed on the outer surface of the discharge pipe 9. A group of supporting legs 11 are fixedly connected to the outer surface of the mixing box 1. The valve 10 is a prior art and will not be described in detail in this application. By setting the valve 10, the discharge pipe 9 can be opened and closed, thereby facilitating the control of the discharge of the mixed liquid.

[0034] See also Figure 1 and Figure 2 A set of feed pipes 12 are fixedly connected to the top surface of the mixing box 1 , and the biopharmaceutical liquid to be mixed is transported to the interior of the mixing box 1 through the feed pipes 12 .

[0035] See also Figure 2 , Figure 3 and Figure 4 Two vibration mechanisms 8 are arranged inside the stirring box 1. The vibration mechanism 8 includes a rotating rod 801 rotating inside the stirring box 1. The outer surface of the rotating rod 801 is fixedly connected to a pulley. When the device stirs and mixes the biopharmaceutical liquid, the rotation of the stirring roller 2 can drive the rotating rod 801 to rotate under the transmission action of the belt, thereby simplifying the power structure of the device.

[0036] See also Figure 4 A rotating rod 802 is arranged below the rotating rod 801. The rotating rod 802 penetrates the mixing box 1 and is rotatably connected to the mixing box 1. An eccentric wheel 803 is fixedly connected to the outer surface of the rotating rod 802. The rotation of the rotating rod 802 can drive the eccentric wheel 803 to rotate. The mixing box 1 provides support and stability for the rotation of the rotating rod 802 to prevent the rotating rod 802 and the eccentric wheel 803 from shaking during the rotation process.

[0037] The outer surface of the eccentric wheel 803 is provided with a grooved slide bar 804, and the two ends of the filter screen 3 are fixedly connected to the two grooved slide bars 804 respectively. When the eccentric wheel 803 rotates, it can drive the grooved slide bar 804 to slide up and down, thereby driving the filter screen 3 to vibrate up and down, and vibrate and filter the residue and particulate matter in the mixed liquid.

[0038] The outer surface of the grooved slide bar 804 is slidably connected to two fixed blocks 805, each of which is fixedly connected to the mixing box 1. The fixed blocks 805 provide support for the up and down sliding of the grooved slide bar 804 to prevent the grooved slide bar 804 from deviating from the sliding trajectory due to external vibrations or collisions, thereby causing the filter screen 3 to tilt and affecting the subsequent collection box 5 for the collection effect of residues and particulate matter.

[0039] The bottom end of rotating rod 1 801 is fixedly connected with bevel gear 1 806, and one end of rotating rod 2 802 is fixedly connected with bevel gear 2 807. Bevel gear 1 806 is meshed with bevel gear 2 807. The rotation of rotating rod 1 801 drives bevel gear 1 806 to rotate. Under the action of meshing, bevel gear 1 806 drives bevel gear 2 807 to rotate, thereby driving rotating rod 2 802 to rotate.

[0040] Working principle: the staff first transports the biopharmaceutical liquid to be mixed into the mixing box 1 through the feed pipe 12, and then starts the motor. The rotation of the motor drives the stirring roller 2 to rotate, and the rotation of the stirring roller 2 drives the sleeve 6 and the stirring rod 7 to rotate, so as to stir and mix the medical liquid. While the stirring roller 2 rotates, under the transmission action of the belt, the rotating rod 801 will also rotate accordingly. The rotation of the rotating rod 801 drives the bevel gear 806 to rotate. Under the action of meshing, the bevel gear 806 drives the bevel gear 807 to rotate, thereby driving the rotating rod 802 to rotate. The rotation of the rotating rod 802 can drive the eccentric wheel 803 to rotate inside the grooved slide bar 804, so that the grooved slide bar 804 slides up and down, and finally drives the filter screen 3 to vibrate up and down inside the mixing box 1, and the residue and particulate matter in the mixed liquid are screened and filtered, thereby reducing the possibility of clogging of the discharge pipe.

[0041] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
