DETAILED DESCRIPTION

[0015] The embodiments of the present invention are described in detail below. The embodiments are implemented on the premise of the technical solution of the present invention, and detailed implementation methods and specific operation processes are given, but the protection scope of the present invention is not limited to the following embodiments.

[0016] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8A desktop active drug sampling device of the present invention has a hollow tank body 1, the top of the tank body 1 is open and the bottom is closed, a placement port 24 is provided at the top of the tank body 1, and a sampling component is embedded in the placement port 24; the sampling component includes a feeding tube 5, a hollow cylinder 6 and four partitions 25, the feeding tube 5 is a hollow structure, the hollow cylinder 6 is coaxially arranged on the central axis of the feeding tube 5, the feeding tube 5 and the hollow cylinder 6 are integrally formed by four partitions 25 distributed at equal angles, that is, four partitions 25 are distributed at equal angles between the inner wall of the feeding tube 5 and the outer wall of the hollow cylinder 6, and the feeding tube 5, the hollow cylinder 6 and the four partitions 25 are an integrally formed structure. The inner wall of the feeding tube 5, the outer wall of the hollow cylinder 6 and the four partitions 25 are combined to form four fan-shaped feeding chambers 7. The specifications of the four fan-shaped feeding chambers 7 are the same. A piston rod 26 is movably arranged in the feeding chamber 7. A fan-shaped piston 8 is fixedly installed at the end of the piston rod 26. A rotating rod 9 is movably inserted in the hollow cylinder 6. A rotating frame 10 is installed after one end of the rotating rod 9 passes through the upper end of the feeding tube 5. The rotating frame 10 has a cross-shaped structure. Labels 18 are provided on the rotating frame 10. The other end of the rotating rod 9 passes through the lower end of the feeding tube 5 and is connected to a transition sleeve 11. A feeding port 12 is provided on the transition sleeve 11. The feeding port 12 can be replaced with sleeves 27 of different lengths. Three blind holes 19 for blocking materials are also provided on the transition sleeve 11, a material taking port 12 and the three blind holes 19 for blocking materials are arranged along the circumferential direction of the hollow cylinder 6, a docking plate 20 is also provided at the lower end of the material taking pipe 5, four plug-in tubes 21 are provided on the lower end surface of the docking plate 20, a first step 22 is provided at the lower end edge of the docking plate 20, a second step 23 is provided on the side of the transition sleeve 11 opposite to the docking plate 20, the docking plate 20 is movably pressed on the second step 23 of the transition sleeve 11 through the first step 22, and the four plug-in tubes 21 are respectively inserted in the blind holes 19 for blocking materials and the material taking port 12, that is, through the effective cooperation between the transition sleeve 11 and the docking plate 20, the rapid adjustment and docking of the material taking port 12 can be realized. The four plug-in tubes 21 correspond to four material taking cavities 7 respectively, and one material taking port 12 and three material blocking blind holes 19 also correspond to four material taking cavities 7 respectively. Of course, the four plug-in tubes 21 correspond to one material taking port 12 and three material blocking blind holes 19 respectively, and normal material taking can be achieved after the material taking port 12 is sleeved with a sleeve 27.It should be noted that the reason why the label 18 is provided on the rotating frame 10 with a cross-shaped structure is that when the rotating rod 9 rotates, it will drive the transition sleeve 11 to move synchronously, and the transition sleeve 11 is located at the bottom, and it is not easy for the operator to intuitively see the real-time position of the three material blocking blind holes 19 and one material taking port 12 on the transition sleeve 11. In other words, the operator cannot know exactly to which area the three material blocking blind holes 19 are rotated, nor can he know exactly to which area the one material taking port 12 is rotated, which increases the difficulty of taking materials. The present application arranges the label 18 on the rotating frame 10 with a cross-shaped structure, so that the operator can quickly rotate the three material blocking blind holes 19 and one material taking port 12 into place, and realize the corresponding card connection, so as to quickly realize the subsequent material taking operation.

[0017] The inner bottom of the tank body 1 is provided with a stirring assembly, one side of the tank body 1 is provided with an inlet 2, and the other side of the tank body 1 is provided with an outlet 3. The stirring assembly includes a stirring motor, a stirring shaft 13 and a stirring blade 14, the output end of the stirring motor is connected to the stirring shaft 13, the stirring shaft 13 is installed at the inner bottom of the tank body 1, and the stirring blade 14 is installed on the side wall of the stirring shaft 13. The stirring motor is purchased directly from the market. The working principle of the stirring component is: when the material taking component needs to be cleaned, first fill the corresponding cleaning agent into the tank body 1 from the inlet 2, then turn on the stirring component, and the stirring motor of the external power supply drives the stirring shaft 13 to rotate, so that the rotating stirring shaft 13 drives the stirring blades 14 to rotate, and the rotating stirring blades 14 quickly and fully stir the cleaning liquid in the tank body 1, so that the material taking component placed on the tank body 1 can be cleaned very conveniently, and then the operator flushes the material taking chamber 7 by pulling the piston rod 26 back and forth, and finally, the cleaning agent is discharged from the discharge port 3 to the outside of the tank body 1. Of course, in order to improve the cleaning effect of the material taking component, the above cleaning process can be repeated several times.

[0018] A support plate 4 is horizontally arranged on the upper part of the tank body 1, and the support plate 4 is movably inserted on the tank body 1. A drying component is arranged in the tank body 1, and the drying component is located above the support plate 4. The drying component includes a heating electrode 15, and the heating electrode 15 is installed on the inner wall of the tank body 1, and the heating electrode 15 is externally connected to a power supply. Among them, the heating electrode 15 is purchased directly from the market. The working principle of the drying component is: when it is necessary to dry the material taking component, the heating electrode 15 can be controlled to operate, so that the material taking component can be dried quickly, which is convenient for the subsequent re-sampling operation of the material taking component. The working principle of the heating electrode 15 is mainly based on the principle of converting electrical energy into thermal energy. When current passes through the heating electrode 15, electrons move in the conductor under the action of the electric field force, collide with the atoms or molecules of the conductor, resulting in energy transfer, and the movement speed of atoms or molecules increases, thereby generating heat.

[0019] In addition, a sealing sleeve 16 is sleeved on the placement opening 24, and the diameter of the upper end of the material taking tube 5 is larger than the diameter of the lower end of the material taking tube 5. The upper end of the material taking tube 5 is clamped on the sealing sleeve 16 to achieve sealing of the two in the contact area. A limiting hole 17 is also provided on the support plate 4 at a position relative to the material taking tube 5, and the material taking tube 5 is inserted into the limiting hole 17. The height dimension of the plug-in tube 21 is larger than the height dimension of the first step 22.

[0020] The working principle of the desktop active drug sampling device is as follows: first, the operator takes out the sampling assembly from the placement port 24, then puts a sleeve 27 of appropriate length on the material taking port 12, then rotates the rotating frame 10 at the end of the rotating rod 9 to make the material taking port 12 concentric with the plug-in tube 21 to be sampled, and then pushes the material taking tube 5 downward as a whole to make the docking plate 20 and the transition sleeve 11 pressed together, so that it can be placed close to the active drug bottle as a whole, and then pulls the piston rod 26 upward to suck the active drug in the active drug bottle into the material taking chamber 7, then rotates the rotating frame 10 to make the transition sleeve 11 rotate, pulls the rotating rod 9 upward to separate the docking plate 20 from the transition sleeve 11, and finally places it on a balance scale for weighing, so as to achieve accurate sampling.

[0021] The desktop active drug sampling device can sample different active drugs through different sampling chambers 7, thereby realizing simultaneous sampling of multiple active drugs, which is convenient and fast, realizes accurate dosage sampling, reduces the difficulty of operation, improves the use efficiency and overall convenience, and effectively solves the technical problem that the existing active sampling device can only sample a single active drug. At the same time, the active drug sampling device of the present invention adopts a desktop structure, that is, it is placed on the desktop, with a small size, simple design, easy to move and install, and can easily adapt to different working environments; in addition, the present invention can also realize the integrated operation of cleaning and drying, that is, through the stirring component and the drying component, it can realize the rapid automatic cleaning and rapid automatic drying of the sampling component during the static process, improve the cleaning and drying efficiency, and effectively solve the technical problems that the existing single-use active sampling devices need to be cleaned and dried one by one after use, the operation is relatively cumbersome, time-consuming and labor-intensive, and the cleaning and drying efficiency is not high.

[0022] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
