Description

Technical Field

[0001] The present invention relates to the technical field of automatic liquid dispensing, and in particular to an automatic liquid dispensing device based on intelligent calculation. Background Art

[0002] In medication scenarios such as hospitals or pharmacies, strict selection and preparation of liquid medicines or other liquids are required. At present, most liquid preparation is still done manually. Due to the accuracy and precision of drug dosage, manual operation is prone to errors, and the weighing process is cumbersome and time-consuming, which reduces the efficiency of drug preparation and increases the workload. For this reason, the application of automatic liquid preparation system can not only improve the efficiency of drug preparation and reduce labor costs, but also improve the safety of drug use, solve the problem of manual operation that cannot be completely replaced by the existing automatic liquid preparation system, and achieve a higher level of automated drug preparation.

[0003] Automatic dispensing devices are devices used to accurately mix and prepare drugs, medicines or liquid formulations. The main purpose is to ensure the accuracy of drug dosage, consistency of drug formulation and safety of patient medication.

[0004] Current dispensing devices usually use advanced technology and design to meet the needs of different types of drugs and liquid formulations. For example, automatic drug dispensing systems can automatically mix and prepare specific doses of drugs according to doctor's orders and patient needs, and are usually integrated with medical record systems to ensure that patients' personal information and prescriptions are accurate. However, the high cost of existing automatic dispensing devices is a major problem, which may be unaffordable for some small medical institutions or resource-poor areas.

[0041] Working principle of the quantitative liquid storage mechanism 8: the liquid storage bottle 801 adopts the needle tube principle, and the sealing piston 809 and the lifting rod 810 play the function of the needle tube piston. During the upward extraction process, the bottom liquid storage inlet 808 flows liquid into the interior, and during the downward pushing process, the bottom liquid storage outlet 807 discharges the liquid.

[0042] In one embodiment, for the above-mentioned box body 1, heat dissipation grooves 18 are provided on the bottom and bottom of both sides of the box body 1, and a protective cover 19 is provided on the top of the back side of the box body 1 and above the rear plate 13.

[0043] In one embodiment, for the through-hole adjustment mechanism 9, the through-hole adjustment mechanism 9 includes a fixed shaft base 901 arranged at the inner bottom of the box body 1, a four-slotted wheel 902 is arranged at the top of the fixed shaft base 901, an adjustment servo motor 903 is arranged on one side of the fixed shaft base 901, and a dial 904 matching the four-slotted wheel 902 is arranged on the output shaft at the top of the adjustment servo motor 903; an inner telescopic column 905 is arranged at the top of the four-slotted wheel 902, a telescopic sleeve 906 is sleeved on the top of the inner telescopic column 905, and a spring 907 is arranged between the top of the inner telescopic column 905 and the inner bottom of the telescopic sleeve 906, Anti-rotation side strips 908 are provided on both sides of the inner telescopic column 905, and anti-rotation grooves matching the anti-rotation side strips 908 are provided on both sides of the telescopic sleeve 906; a clamping block 909 is provided on the top of the telescopic sleeve 906, and a clamping groove for the clamping block 909 is provided at the bottom of the T-shaped convex disc 805, so that the four-slotted wheel 902 can be driven to rotate through the action of the bottom adjustment servo motor 903, and the top telescopic sleeve 906 can be driven to rotate, thereby realizing the rotation of the T-shaped convex disc 805 at the bottom of the liquid storage bottle 801, and completing the switching of the liquid storage outlet 807 and the liquid storage inlet 808 at the bottom of the liquid storage bottle 801.

[0044] The working principle of the through-hole adjustment mechanism 9 is as follows: the servo motor 903 is adjusted to drive the dial 904 to rotate. During the rotation of the dial 904, the four-slotted wheel 902 is turned to perform a quantitative rotation of 90 degrees. After each rotation, the telescopic sleeve 906 will drive the T-shaped convex plate 805 to rotate 90 degrees, and finally drive the rotatable chassis 804 to rotate 90 degrees. If the infusion through-hole 806 provided on the rotatable chassis 804 coincides with the liquid storage outlet 807 at this time, then after the rotatable chassis 804 rotates 90 degrees, the infusion through-hole 806 and the liquid storage outlet 807 are staggered, and the infusion through-hole 806 is located at the bottom of the sealed liquid storage bottle 801, and no liquid flow will occur at this time; until the rotatable chassis 804 rotates 90 degrees again, the infusion through-hole 806 coincides with the liquid storage inlet 808, and at this time, the liquid storage bottle 801 can flow liquid into the inside through the liquid storage inlet 808.

[0045] In one embodiment, for the quantitative drawing mechanism 12, the quantitative drawing mechanism 12 includes a drawing servo motor 1201 arranged at the top of the top beam frame 11, the output shaft of the drawing servo motor 1201 is provided with a threaded rod 1202, and the bottom of the top beam frame 11 is provided with two limit rods 1203, and the outer side of the threaded rod 1202 is provided with a lifting block 1204, and one side of the lifting block 1204 is provided with a limit side ear 1205 that cooperates with the limit rod 1203; the other side of the lifting block 1204 is provided with an embedded card slot 1206, and the internal plate 812 is connected to the embedded card slot 1206. The inner plate 811 and the inner card slot 1206 are connected by bolts, so that the lifting block 1204 and the threaded rod 1202 can cooperate to drive the inner plate 812 to move up and down, that is, drive the sealing piston 809 and the lifting rod 810 inside the liquid storage bottle 801 to move up and down, and finally change the capacity of the liquid inside the liquid storage bottle 801 during the lifting and lowering movement of the sealing piston 809; at the same time, the lifting degree of the sealing piston 809 can be controlled by adjusting the speed and workload of the pulling and pulling servo motor 1201, so as to achieve the purpose of high-precision adjustment of the internal solution volume.

[0046] The working principle of the quantitative drawing mechanism 12 is as follows: the drawing servo motor 1201 drives the threaded rod 1202 to move, and the lifting block 1204 can be lifted and lowered under the drive of the threaded rod 1202. Since the lifting block 1204 is fixedly connected to the inner plate 811, the inner plate 811 can drive the lifting rod 810 and the sealing piston 809 to lift and lower. Through the calculation of the processor inside the electric control box 10, the operator can input the configuration amount of the liquid. After the intelligent calculation, the processor obtains the rotation amount of the drawing servo motor 1201. After the rotation amount is completed, the sealing piston 809 can just reach the volume change degree. In the process of volume transformation, the solution is subjected to pressure changes and flows inside the liquid storage bottle 801.

[0047] In addition, the intelligent calculation process includes: first, determine the lifting distance of the sealing piston 809 inside the liquid storage bottle 801, and the relevant parameters of the pulling servo motor 1201, such as the motor speed, torque and pitch of the threaded rod. Establish a mathematical model between the quantitative lifting of the liquid and the rotation of the motor, and take into account the relationship between the rotation of the threaded rod 1202 and the lifting of the lifting block 1204, as well as the relationship between the lifting of the sealing piston 809 and the volume change of the liquid. Based on the intelligent control algorithm, according to the real-time liquid demand and liquid volume, calculate the working parameters required by the pulling servo motor 1201, including the speed and rotation angle, to achieve the quantitative lifting of the sealing piston. Finally, it is necessary to continuously optimize the intelligent control algorithm, adjust the parameters and algorithms according to the actual working conditions and data feedback, so as to improve the accuracy and efficiency of liquid configuration.

[0049] In one embodiment, for the above-mentioned bottle hanging mechanism 14, the bottle hanging mechanism 14 includes a vertical hanging guide rod 1401 arranged at the bottom of the rear plate 13, a double-plate rail 1402 is arranged on one side of the vertical hanging guide rod 1401, and a plurality of equidistantly arranged vertical through holes 1403 are opened on both sides of the double-plate rail 1402, and a mounting ear 1404 is arranged inside the double-plate rail 1402, and the mounting ear 1404 and the vertical through holes 1403 are kept connected by bolts, and a bottle placing frame 1405 is arranged on one side of the mounting ear 1404, so that the height of the bottle placing frame 1405 can be changed by adjusting the position of the mounting ear 1404 to meet the placement of different medicine bottles or medicine bags, and the hose is inserted into the medicine bottle or medicine bag, and the other end of the hose is inserted into the external liquid inlet 21, and the liquid inlet hose and the liquid outlet hose are combined to achieve complete communication of the liquid from the medicine bottle to the external liquid outlet 22, thereby realizing automatic configuration of the liquid.

The liquid in the box body 1 is transmitted to the liquid storage inlet 808 by the liquid inlet hose, and the switching between the liquid storage inlet 808 and the liquid storage outlet 807 at the bottom of the liquid storage bottle 801 is changed by the action of the through-hole adjustment structure 9. Then, under the action of the quantitative drawing and pulling mechanism 12, the sealing piston 809 is raised and lowered through intelligent calculation control to control the storage capacity of the liquid in the liquid storage bottle 801 (the operator needs to set the storage capacity in each liquid storage bottle 801 through the display control panel 5, and after setting, the internal processor of the electric control box 10 is used to calculate the working parameters of the servo motor through the pre-set program). After the liquid in the liquid storage bottle 801 is extracted or discharged, the liquid is transferred to the liquid outlet 4 through the liquid outlet hose, and the operator can use a container to collect the liquid at the corresponding liquid outlet 22 to complete the liquid preparation.

[0052] To sum up, with the help of the above-mentioned technical scheme of the present invention, by adopting a box-type structure design, the back of the box 1 is used to place medicine bottles for easy liquid collection, and the front end is used for automatic liquid discharge to realize quantitative preparation of liquid, and multiple groups of quantitative liquid storage mechanisms 8 are integrated inside the box 1, which can realize the simultaneous storage and management of multiple liquids, thereby realizing simple and accurate automatic liquid preparation in medical scenarios and improving liquid preparation efficiency; at the same time, by using intelligent calculation methods, by inputting preset liquid storage volume and liquid collection volume, the workload of the servo motor is calculated, and the liquid circulation volume can be strictly controlled, thereby realizing accurate liquid preparation. By adopting the through-hole adjustment mechanism 9, the liquid storage outlet 807 and the liquid storage inlet 808 at the bottom of the corresponding liquid storage bottle 801 can be automatically adjusted, and the principle of periodic quantitative rotation can be used to realize the penetration of a single through-hole, complete the switching of liquid inlet and outlet of the liquid storage bottle 801, and avoid liquid leakage; at the same time, the quantitative pulling mechanism 12 can be used to drive the lifting rod 810 inside the liquid storage bottle 801 to perform quantitative lifting and lowering, change the pressure inside the liquid storage bottle 801, realize the extraction and discharge of the internal liquid, and then control the volume of the liquid inside the liquid storage bottle 801 to realize automatic liquid preparation. By setting the bottle hanging mechanism 14, the height of the bottle frame 1405 can be changed by adjusting the position of the mounting lug 1404 in the double-plate track 1402, so as to meet the placement of different types of medicine bottles. In medical scenarios, a large number of medicine bottles or medicine bags can be placed, which is convenient for liquid storage bottles to take liquids and store them.
