DETAILED DESCRIPTION

[0016] Embodiments of the present application are described in detail below with reference to examples shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0017] As shown in Figure 1 , a rotary self-service reagent adding device according to an embodiment of the present application comprises a base 1, a rotating component 2 and a lifting component 3. The rotating component 2 is disposed on the base 1 and is rotatable relative to the base 1, and a plurality of reagent adding units 4 are disposed on the rotating component 2 and are arranged at intervals along the circumference of the rotating component 2. The lifting component 3 is used to place a reaction container 5 thereon, and the lifting component 3 is movable in the up-down direction to drive the reaction container 5 to move in the up-down direction. When adding reagent, the rotating component 2 is rotated to make one of the reagent adding units 4 correspond to the reaction container 5, and the lifting component 3 drives the reaction container 5 to move upward so that the reagent adding unit 4 adds reagent into the reaction container 5. After the reagent adding is completed, the lifting component 3 drives the reaction container 5 to move downward.

[0018] The rotary self-service dosing device of this invention controls different dosing units 4 to add drugs into the reaction container 5 through a rotating component 2. Furthermore, while adding drugs into the reaction container 5, the lifting component 3 moves the reaction container 5 to shorten the distance between the dosing unit 4 and the reaction container 5, preventing the drugs from dripping to the outside during dosing. Thus, the two-dimensional motion of rotation and lifting simplifies the dosing process, makes operation convenient, increases work efficiency, saves time and manpower, reduces the workload of laboratory technicians, minimizes contact between staff and chemicals, and ensures the health of staff. Moreover, the rotary self-service dosing device of this invention has a compact structure, occupies a small area, and saves manufacturing costs.

[0019] In some embodiments, the rotating component 2 includes a mounting plate 21, a rotating element 22, a support portion 23, and a protective cover 24. The mounting plate 21 is disposed on the upper surface of the base 1 and is rotatable relative to the base 1 in the vertical direction. A plurality of dosing units 4 are arranged at intervals along the circumference of the mounting plate 21. The rotating element 22 is disposed in the cavity of the base 1 and is rotatable relative to the base 1. The rotating element 22 is driven by a drive motor (not shown) to rotate. The rotating element 22 is connected to the mounting plate 21 to drive the mounting plate 21 to rotate. The support portion 23 extends in the vertical direction, and its lower end is disposed on the upper surface of the mounting plate 21. The rotating element 22 is connected to the support portion 23. The protective cover 24 is disposed on the upper end of the support portion 23. The protective cover 24 and the mounting plate 21 are arranged at intervals in the vertical direction. The support portion 23 is rotatable relative to the protective cover 24.

[0020] Specifically, the rotating part 22 is driven by a drive motor to rotate, thereby causing the mounting plate 21 to rotate, which in turn causes multiple dosing units 4 to rotate in the up-down direction, so as to add different reagents into the reaction vessel 5. This process eliminates the complex structure of multi-axis linkage, and the mechanical structure is stable, has a low failure rate, is easy to process and maintain, and saves costs.

[0021] By setting up protective shields 24, physical isolation is provided, reducing contact between the medicine and staff and ensuring the health of the staff.

[0022] In some embodiments, the dosing unit 4 includes a medicine bottle 41, a dispensing section 42, and a peristaltic pump 43. The medicine bottle 41 is disposed on the upper surface of the mounting plate 21. The dispensing section 42 is disposed at the opening of the medicine bottle 41 and has an outlet 423 through which the medicine in the medicine bottle 41 enters the reaction vessel 5. The peristaltic pump 43 is disposed between the opening of the medicine bottle 41 and the dispensing section 42, and the peristaltic pump 43 is used to control the dispensing volume of the medicine bottle 41.

[0023] Specifically, the peristaltic pump 43 is a high-precision peristaltic pump 43. The amount of reagent added into the reaction vessel 5 is controlled by the peristaltic pump 43, which ensures the accuracy of the dosage and is easy to control.

[0024] In some embodiments, the liquid outlet 42 includes a liquid outlet tube 421 and a liquid outlet needle 422. One end of the liquid outlet tube 421 is connected to the opening of the medicine bottle 41, and the other end of the liquid outlet tube 421 extends upward and is connected to one end of the liquid outlet needle 422. The other end of the liquid outlet needle 422 extends in a first direction away from the support portion 23, and the first direction is orthogonal to the vertical direction. The other end of the liquid outlet needle 422 is bent downward, and the liquid outlet 423 is provided at the other end of the liquid outlet needle 422.

[0025] Specifically, the peristaltic pump 43 pumps the medicine in the medicine bottle 41 into the outlet pipe 421, then through the outlet pipe 421 into the outlet needle 422 and out through the outlet port 423. The outlet port 423 is located directly above the reaction vessel 5, ensuring that the medicine can accurately enter the reaction vessel 5 and reducing splashing.

[0026] In some embodiments, the protective cover 24 is transparent and its outer periphery protrudes from the reaction container 5.

[0027] Specifically, the protective cover 24 is transparent, making it easy for staff to observe. The outer periphery of the protective cover 24 protrudes from the reaction container 5, ensuring that when reagents are added to the reaction container 5, the reagents are not likely to splash onto the staff, and also ensuring that external substances are not likely to fall into the reaction container 5.

[0028] In some embodiments, the lifting component 3 includes a base 31, a lifting part 32, a reaction platform 33, and a stirrer 34. The base 31 is disposed adjacent to the base 1, and the outer wall surface of the base 31 is in close contact with the outer wall surface of the base 1. The lifting part 32 is disposed in the cavity of the base 31, with its lower end disposed on the bottom surface of the cavity of the base 31 and its upper end protruding from the upper surface of the base 31. The lifting part 32 can move vertically relative to the base 31. The reaction platform 33 is disposed above the lifting part 32, and the reaction container 5 is disposed on the reaction platform 33 to increase the contact area between the reaction container 5 and the lifting part 32, ensuring that the reaction container 5 remains stable when moving. The stirrer 34 is disposed on the upper surface of the reaction platform 33 and located below the reaction container 5. The stirrer 34 is used to stir the reagent in the reaction container 5.

[0029] Specifically, when adding reagents into the reaction container 5, first control the lifting unit 32 to descend to the low position, and control the drive motor to drive the mounting plate 21 to rotate, so that the reagent bottle 41 to be added is close to the reaction container 5. When the liquid outlet 423 is directly above the reaction container 5, the mounting plate 21 stops rotating, and the lifting platform is controlled to rise until the liquid outlet 423 is inside the reaction container 5. Then, the peristaltic pump 43 is started to add reagents into the reaction container 5. After completion, the lifting platform is controlled to descend, and the above steps are repeated to add reagents from different reagent bottles 41 into the reaction container 5.

[0030] Specifically, the reaction efficiency of the reagent in the reaction vessel 5 is improved by using a stirrer 34 on the reaction platform 33 to stir the reagent in the reaction vessel 5.

[0031] Specifically, the lifting unit 32 is a lifting motor. The core moving components of the rotary self-service dispensing device in this embodiment of the invention are the drive motor and the lifting motor, which greatly reduces manufacturing costs.

[0032] In some embodiments, the reaction platform 33 may integrate heating and magnetic stirring functions to enable automated color development, reaction, etc., within the reaction vessel 5.

[0033] In some embodiments, the stirrer 34 is a magnetic stirrer 34.

[0034] In some embodiments, the rotary self-service dosing device also includes a controller 6, which can control the start and stop of the drive motor, the start and stop of the peristaltic pump 43, and the lifting and lowering of the lifting part 32, making the operation simple, convenient, efficient, and saving manpower and time.

[0035] In some embodiments, the lifting component 3 further includes a sensor (not shown), which is located on the reaction platform 33. The sensor is used to weigh the reaction container 5. When the weight of the reaction container 5 reaches a preset value, the dosing unit 4 stops adding drugs into the reaction container 5.

[0036] Specifically, the sensor is a weighing sensor. When the weight of the reaction vessel 5 reaches a preset value, the controller 6 controls the peristaltic pump 43 to stop adding the reagent into the reaction vessel 5. Thus, the amount of reagent added is detected by high-precision weighing, ensuring the accuracy of the amount of reagent added.
