Description

Technical Field

[0001] This utility model belongs to the field of reagent pen manufacturing technology, and in particular relates to a raw material mixing device for reagent pen manufacturing. Background Technology

[0002] A reagent pen is a common medical device, mainly used to facilitate convenient testing for medical staff or patients. A reagent pen mainly consists of two parts: an outer shell and an internal reagent. In the production and preparation process of a reagent pen, a raw material mixing device is usually used to mix the raw materials of the reagent.

[0003] A document with publication number CN215996257U discloses a raw material mixing device for the production of EMA antibody reagents, including a mixing chamber. A motor is fixedly connected to the top of the mixing chamber. The output shaft of the motor passes through the top of the mixing chamber and is fixedly connected to a rotating shaft. A drive gear is fixedly sleeved on the end of the rotating shaft away from the motor. A mixing disc is rotatably connected to the bottom of the mixing chamber. Two sets of mixing rods are fixedly connected to the bottom of the mixing disc.

[0004] However, it still has the following drawbacks in practical use:

[0005] The raw material mixing device described above has a raw material tank fixedly installed on the side wall of the mixing tank, and an infusion pump is installed inside the raw material tank. The infusion pump introduces the liquid raw material in the raw material tank into the mixing tank for mixing. However, during use, some of the liquid raw material will remain in the raw material tank, which is not convenient to clean. The remaining liquid raw material will affect the storage of liquid raw material in the next time, and thus affect the mixing of raw materials.

[0006] The raw material mixing device described above has a feed hopper fixed to the top of its mixing chamber. Solid raw materials are added into the mixing chamber through the feed hopper. However, it is not convenient to add solid raw materials quantitatively, thus making it inconvenient to add solid raw materials.

[0007] To address these issues, we provide a raw material mixing device for reagent pen production. Utility Model Content

[0008] The purpose of this invention is to provide a raw material mixing device for reagent pen production. The device uses a lifting block to drive a cleaning pipe and a high-pressure nozzle to flush the inner wall of the liquid tank, and a sponge ring to absorb the liquid on the inner wall of the liquid tank.

The end of the connecting pipe away from the liquid tank passes through the top of the mixing tank and extends to the upper interior of the mixing tank.

[0016] A further feature of this invention is that the inner side of the sponge ring is uniformly provided with grooves, and the interior of the grooves is fitted with protrusions with gaps. One end of each protrusion is welded to the outer side of the ring frame.

High-pressure water is sprayed onto the inner wall of the liquid tank through the cleaning pipe and a high-pressure nozzle, cleaning the liquid tank with the high-pressure water flow. Simultaneously, a sponge ring absorbs and wipes away the liquid adhering to the inner wall of the liquid tank, thus achieving cleaning of the liquid tank.

At this point, the pusher plate adds the fixed raw material to the mixing tank through a feeding pipe, achieving quantitative addition of solid raw materials. This facilitates the feeding of solid raw materials and makes the mixing of reagent raw materials more convenient.
