Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, and particularly relates to a liquid adding and diluting device. Background Art

[0002] During the medical inspection process, in order to adjust the concentration of the sample solution to an appropriate range to obtain more accurate results, medical staff usually use a liquid adding and diluting device to add liquid and dilute the sample solution. The existing liquid adding and diluting devices usually consist of a fixed seat, a liquid injection box, and a placement seat.

[0003] For example: The utility model with the application number CN202122389987.9 discloses a liquid adding and diluting device for a clinical laboratory, which specifically includes a transparent cover body 1, an outer cylinder 2, an outer cylinder horizontal linear driving mechanism 3, a container fixed seat 4, a fixed seat rotating mechanism 5, a lifting mechanism 6, a turntable 7, a turntable rotating mechanism 8, and a measuring cylinder 9. A lifting mechanism 6 is arranged inside the transparent cover body 1. A turntable rotating mechanism 8 is fixed on the piston rod of the lifting mechanism 6. A turntable 7 is fixed on the output shaft of the turntable rotating mechanism 8. Several measuring cylinders 9 are evenly distributed on the turntable 7. The measuring cylinders 9 are provided with scales. This utility model drives the container to enter and exit the transparent cover body through the outer cylinder horizontal linear driving mechanism. Rotate the container through the fixed seat rotating mechanism. Drive the measuring cylinder to enter and exit the transparent cover body through the lifting mechanism. Rotate the turntable through the turntable rotating mechanism so that different measuring cylinders are aligned with the container. This application improves the efficiency of sample dilution. Avoid contaminating the sample during operation through the transparent cover body.

[0004] However, for the current traditional liquid adding and diluting devices, usually medical staff need to first inject the dilution solution into the container containing the sample solution through a dropper or a syringe, and then mix the dilution solution and the sample solution by stirring or shaking. The operation is relatively cumbersome, which increases the labor intensity of medical staff and is inconvenient to use. Content of the Utility Model

[0005] In view of this, the present utility model provides a liquid adding and diluting device, which has a placement seat capable of mixing while injecting diluting liquid. By starting the second motor, the second motor drives the first pulley to rotate. During the rotation of the first pulley, the second pulley is driven to rotate through a transmission belt. During the rotation of the second pulley, the rotating seat is driven to rotate. During the rotation of the rotating seat, the placement seat drives the container to rotate. During the rotation of the placement seat, the control push block contacts the control pressure seat, causing the control pressure seat to squeeze the control push block, so that the control push block drives the placement seat to move upward, jacking up the placement seat and driving the lifting seat to slide in the rotating seat. After the control push block and the control pressure seat are misaligned, the placement seat automatically resets under the action of gravity, thereby causing the placement seat to generate intermittent vibrations. The impact force when the placement seat drops can be buffered through the setting of the rubber pad, and the vibration of the placement seat drives the container filled with sample liquid to vibrate.
