Description

[0002] With the worsening of environmental pollution, the accelerated pace of life and the formation of bad living habits, almost everyone has been sick. When the condition worsens and cannot be overcome by the body's immune system, it can only be treated and maintained by drugs. Therefore, drug safety is as important to human health as food safety. In order to ensure the safety of drugs, relevant departments will regularly conduct drug sampling and testing from major drug manufacturers.

[0003] At present, in the detection of liquid drugs, liquid extraction tools such as rubber-tipped droppers and syringes are mostly used to extract a certain amount of liquid drugs from the drug container, and then the extracted liquid drugs are injected into a pre-prepared sample container, which is usually a test tube. Then, the drug detection work is carried out through the sample test tube containing the liquid drug. However, due to the differences between various drugs and the need to sample multiple drugs at a time, in order to ensure the effectiveness of the detection work, the extraction tool needs to be cleaned after each liquid drug is extracted, or a new extraction tool needs to be replaced before sampling the next liquid drug, which leads to slow progress of the sampling work and reduces the efficiency of drug detection.

DETAILED DESCRIPTION

[0026] The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.

[0027] Reference Figure 1-Figure 7 , a liquid medicine detection sampling device, comprising a workbench 1, a placement plate 2 is fixedly connected to the right end of the workbench 1 for placing the liquid medicine to be sampled. Two sampling mechanisms symmetrically arranged front and back are provided at the upper end of the workbench 1 and near the placement plate 2. The sampling mechanism comprises a cylinder 3 fixedly connected to the upper end of the workbench 1, a rotating column 4 is movably inserted on the cylinder 3, a rotating plate 5 is fixedly connected to the upper end of the rotating column 4, and the rotating plate 5 can be rotated by the rotating column 4, so as to be conveniently rotated from the workbench 1 to the top of the placement plate 2. A test tube plug 6 is vertically fixed through the upper end of the rotating plate 5, and a sealing rubber ring is provided at the lower end of the test tube plug 6. The lower end of the test tube plug 6 can be directly inserted into the mouth of the test tube, and the test tube is not easy to fall off. A liquid extraction tube 7 is vertically fixed through the upper end of the rotating plate 5 and on the side of the test tube plug 6 away from the rotating column 4. The lower end of the liquid extraction tube 7 is connected with a sampling hose 9, and the sampling hose 9 is conveniently placed in the liquid medicine to be sampled. The liquid extraction tube 7 and the upper end of the test tube plug 6 are connected to a first connecting tube 8, and a second connecting tube 10 vertically penetrates the test tube plug 6, and the upper end of the second connecting tube 10 is connected to a pipeline connecting head 11. Specifically, when the sampling hose 9 in the sampling mechanism is rotated to the top of the placement plate 2, it is only necessary to generate negative pressure at the pipeline connecting head 11 to draw air into the test tube through the second connecting tube 10, and then under the action of negative pressure, suction can be generated at the sampling hose 9, so that the liquid medicine can be sucked into the test tube to complete the sampling work.

[0028] A mounting frame is provided above the two sampling mechanisms, and the mounting frame includes two vertical poles 12 fixedly connected to the upper end of the workbench 1, the upper ends of the two vertical poles 12 extend to the top of the sampling mechanism and are commonly fixedly connected to a mounting plate 13, a negative pressure pump 14 is fixedly installed on the upper end of the mounting plate 13, and the suction end of the negative pressure pump 14 is connected to a suction hose 15, and the end of the suction hose 15 away from the negative pressure pump 14 is connected to a first pipe plug 16 matching the pipe connecting head 11. After the sampling mechanism is rotated to the top of the placement plate 2, it is only necessary to manually insert the first pipe plug 16 into the corresponding pipe connecting head 11, so that the negative pressure pump 14 can be used to generate negative pressure, thereby automatically extracting liquid medicines, and the extraction amount can be controlled according to the extraction gas amount of the negative pressure pump 14, and the sampling work is easy and effective.

[0029] A first spring 17 is fixedly connected to the inner bottom wall of the cylinder 3, a circular plate is fixedly connected to the upper end of the first spring 17, the upper end of the circular plate is coaxially rotatably connected to the lower end of the rotating column 4, and the rotating column 4 can move up and down and rotate through the cylinder 3. Under the condition of no external force, the rotating column 4 maintains the highest position. An inverted L-shaped limit slide 18 is provided on the outer circumferential surface of the cylinder 3, and the limit slide 18 is composed of a horizontal slide and a vertical slide. A movable groove 19 parallel to the vertical slide is provided on the upper end of the rotating column 4. A push plate 20 is slidably connected in the movable groove 19, and the upper end of the push plate 20 extends to the top of the rotating plate 5. One end of the push plate 20 located in the movable groove 19 is fixedly connected to a limit slider 21, and the limit slider 21 penetrates the inner wall of the movable groove 19 and slides through the limit slide 18. A second spring 22 is fixedly connected between the end of the push plate 20 away from the limit slider 21 and the inner wall of the movable groove 19. The second spring 22 serves to hold the limit slider 21 so that its front end remains outside the limit slide 18. When the first spring 17 is not subjected to external force, the limit slider 21 is at the position height of the horizontal slide. At this time, the rotating column 4 can be rotated to a certain angle to rotate the sampling hose 9 to the top of the placement plate 2. At the same time, the rotating column 4 is also rotated to the horizontal slide. At this time, the rotating column 4 cannot be lifted or lowered vertically.

[0030] A limiting mechanism is provided on one side of the cylinder 3, and the limiting mechanism includes a spring box 23 fixedly connected to the upper end of the workbench 1 and corresponding to the position of the vertical slide. A limiting block 24 is slidably inserted at one end of the spring box 23 close to the vertical slide. A third spring is fixedly connected between the limiting block 24 and the inner wall of the spring box 23. The cross-section of the limiting block 24 is trapezoidal and the inclined surface is arranged upward. Specifically, when the sampling mechanism is rotated to the top of the workbench, the rotating column 4 can be pressed downward. When the rotating column 4 moves downward, the limiting slider 21 moves downward at the same time until it contacts the inclined surface of the limiting block 24. After pushing it into the spring box 23, it moves to the bottom of the limiting block 24. At this time, the limiting block 24 cannot move up and remains in the vertical slide, and then the rotating column 4 cannot rotate, so that the position of the sampling mechanism remains stable.

[0031] When it is necessary to rotate the sampling mechanism again, it is only necessary to push the corresponding push plate 20 to compress the second spring 22. The movement of the push plate 20 can drive the limit slider 21 to move, so that the outer end moves into the limit slide 18. At this time, the limit block 24 cannot limit the limit slider 21. The rotating column 4 can move upward under the action of the first spring 17, so that the limit slider 21 moves to the position height of the horizontal slide again, and the sampling mechanism can be rotated.

[0032] A cleaning mechanism is provided on the right side of the two sampling mechanisms, and the cleaning mechanism includes a telescopic cylinder 25 fixedly installed on the upper end of the workbench 1, and the telescopic end of the telescopic cylinder 25 is fixedly connected to a lifting plate 26, and a matching water injection pipe 27 is fixedly connected to the upper end of the lifting plate 26 and at a corresponding position below the test tube plug 6, and a water pump 28 is fixedly installed on the lifting plate 26 and on one side of the water injection pipe 27, and the water injection end of the water pump 28 is connected to one side of the water injection pipe 27.

[0033] Two electric telescopic rods 30 are fixedly installed on the upper end of the mounting plate 13. The telescopic ends of the electric telescopic rods 30 extend to the bottom of the mounting plate 13 and are fixedly connected to the end plates 31. The lower ends of the two end plates 31 are fixedly connected to the second pipe plugs 32. The two second pipe plugs 32 correspond to the positions of the two pipe connecting heads 11 respectively. Two air pumps 29 are installed on the upper end of the mounting plate 13. The discharge ends of the two air pumps 29 are connected to the two second pipe plugs 32 through hoses respectively. The air pumps 29 have a heating function and can pump heated air.

[0034] It should be noted that both the water pump 28 and the air pump 29 are provided with a one-way valve.

[0035] Specifically, when the sampling mechanism is rotated to the top of the workbench 1 after use and maintains a stable state, the telescopic cylinder 25 can drive the lifting plate 26 to move up, so that the water injection pipe 27 is connected to the test tube plug 6, and the electric telescopic rod 30 at the corresponding position can drive the end plate 31 to move down, so that the second pipeline plug 32 is connected to the pipeline connecting head 11, and then the water pump 28 can pump water into the water injection pipe 27, and the water in the water injection pipe 27 can enter the first connecting pipe 8, the liquid extraction pipe 7 and the sampling hose 9 through the test tube plug 6, so as to achieve the cleaning effect. After the cleaning work is completed, the water pump 28 stops pumping water, and the air pump 29 works, and the heated air can be pumped into the water injection pipe 27 through the second connecting pipe 10, and then the first connecting pipe 8, the liquid extraction pipe 7 and the sampling hose 9 are all passed through the heated air, so as to achieve the drying effect of each component.

[0036] Water pools 33 are provided at the upper end of the workbench 1 and below the two sampling hoses 9 for collecting water discharged when cleaning the sampling mechanism. The lower end of each water pool 33 is connected to the sewer. Sterilization lamps 34 facing the sampling hoses 9 are fixedly installed at the upper end of the workbench 1 and on one side of the two water pools 33, so as to sterilize and disinfect the sampling hoses 9 after use.

[0037] A storage box 35 is fixedly connected to the upper end of the workbench 1 and on the left side of the sampling mechanism for storing sample tubes.

[0038] The present invention provides two sampling mechanisms, and each sampling mechanism is equipped with an independent cleaning mechanism. After one sampling mechanism is used to complete the sampling of a sample, it can be rotated onto the workbench 1 to automatically perform cleaning and drying operations. While cleaning and drying, another sampling mechanism can be used to sample the next medicine, and this can be repeated without manual cleaning, thus saving the use of sampling tools and greatly improving the sampling efficiency.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
