Description

Technical Field

[0001] The invention relates to the technical field of medical testing equipment, in particular to a medical testing liquid adding and diluting device capable of improving the mixing rate. Background Art

[0002] In medical testing, it is often necessary to dilute the sample liquid before processing and testing. The drug also needs to be diluted before preparation. Before dilution, an appropriate amount of drug solvent needs to be prepared according to the dilution ratio of the drug. First, inject the drug diluent into the test tube, and then add the drug to be diluted. Shake or stir the liquid to dissolve the drug completely to obtain the diluted solution.

[0003] The above-mentioned traditional dilution method requires manual shaking of the drug solvent, and long-term work will cause arm pain in the workers. In order to solve this problem, a machine is usually used to rotate or vibrate the container to dilute the solution in the container. Most traditional diluters have only one speed and cannot meet the demand for speeding up the shaking. For example, some solid medicines are not easily soluble in water. Always using a low-speed shaking machine requires too long mixing time, which reduces the shaking efficiency. At the same time, some medicines are solid and need to be broken up before shaking. The existing solutions are all done manually, and the process is too cumbersome.

At this time, several crushing rods 1201 fixedly mounted on the lower end of the sliding plate 12 also begin to slide up and down with the sliding plate 12 and crush the harder substance to be tested in the spare test tube, thereby facilitating the subsequent mixing work.

[0031] The rotating ring 5 is provided with several connecting tubes 501 which cooperate with the test tubes 24 to be used installed in the installation barrel 2201. The lower ends of the several connecting tubes 501 are respectively connected to the test tubes 24 to be used. The connecting tubes 501 are used to guide the added liquid and also provide the installation barrel 2201 with circular motion around the fixed gear 23.

[0032] The lower end of the through slot 101 is engraved with a scale line 102 for assisting the user in viewing the gear position. The scale line 102 is engraved on the side wall of the box body 1. The user can judge the engagement status of the fifth spur gear 28 and the other three speed gears by observing the scale line 102 at the lower end of the through slot 101. Similarly, the operating lever 8 is also engraved with a scale line for assisting the user in observing the position of the speed gear. Through the cooperation of the two scale lines, the user can accurately operate the operating lever 8 to reach the engagement position and realize real-time speed shifting.

[0033] Implementation method of the present invention: Place the device on a horizontal surface and open the top cover 4 by extracting the handle 7. Insert the test tubes to be tested and shaken into the corresponding installation barrels 2201. Connect the connecting tubes 501 to the corresponding test tube ports. Close the top cover 4 and insert the connecting rod into the vertical groove in the outer wall of the placement barrel 2 to fix the handle 7. Then, relatively hard objects to be tested are placed in another batch of test tubes, and this batch of test tubes is placed on the upper end of the fixed plate 13 , and a plurality of pounding rods 1201 are inserted into the test tubes in sequence to complete the preparation work before mixing.

[0034] After the preparation is completed, move the operating lever 8 horizontally. At this time, the operating lever 8 starts to slide with the fifth spur gear 28. The user can ensure the position of the fifth spur gear 28 according to the scale line, and ensure that the fifth spur gear 28 is first engaged with the fourth spur gear 19. At this time, start the drive motor 26. Since the fourth spur gear 19 has the largest diameter among the three speed gears, the fourth shaft rotates at a slower speed, and the first rotating mechanism and the second rotating mechanism both rotate and mix at a slower speed.

[0035] When the user needs to increase the mixing rate, the user can operate the operating lever 8 to make the fifth spur gear 28 mesh with the other two speed gears respectively to achieve speed change.

[0036] During the operation of the first rotating mechanism and the second rotating mechanism, the crushing rod 1201 slides up and down to crush the harder substance to be tested in the spare test tube. After a period of time, the driving motor is stopped, the top cover 4 is opened, the test tube in the installation barrel 2201 is taken out, and the test tube on the fixed plate 13 is placed into the installation barrel 2201. The top cover 4 is closed, the motor is turned on again and the above operation is repeated to start the next round of work.

[0037] The present invention avoids the defect of traditional manual hand-shaking to mix medical test materials, and provides a function of flexible adjustment of multiple rates while traditional test equipment has only one rate for mixing the test objects, so that users can choose different rates for mixing according to the properties of the test objects, and has a wide range of applications. The first rotating mechanism and the second rotating mechanism of the present invention can make the test material revolve and rotate at a set rate, further improving the mixing rate and reducing time cost. When the equipment is working, the crushing mechanism of the present invention can crush the harder test objects to be tested in advance, and after the test objects in the placement bucket are mixed, they can be taken out and placed in the placement bucket, saving the crushing time and further improving work efficiency.

[0038] 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 principles of the present invention should be included in the scope of protection of the present invention.
