Description

Technical Field

[0001] This utility model relates to the field of medical testing technology, specifically a reagent sampling device for a medical testing department. Background Technology

[0002] Medical laboratory science is a discipline that uses modern physical and chemical methods and techniques for medical diagnosis. It mainly studies how to provide a basis for clinical diagnosis and treatment through laboratory techniques and medical instruments and equipment. Through systematic learning, we will learn how to identify a person's blood type, determine whether a person is anemic, whether liver function is normal, and so on.

[0003] In medical testing, reagents need to be sampled for testing. However, existing sampling devices do not have quantitative sampling devices and can only judge the amount to be taken at one time by visual inspection. The amount of reagent drawn each time is not fixed. Since the sampled reagents cannot be put back into the original reagent bottle, drawing too much will cause waste of reagents, while drawing too little may lead to inaccurate test results.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-7 This utility model provides a technical solution: a reagent sampling device for a medical laboratory, comprising: a sampling tube 1 and a piston rod 3, wherein a sampling head 2 is provided at the bottom of the sampling tube 1, a handle 4 is fixedly connected to the top of the piston rod 3, and a piston block 6 is fixedly connected to the bottom of the piston rod 3, which facilitates the extraction of reagents.

[0027] A positioning plate 8 is fixedly connected to the outer wall of the sampling tube 1. A positioning hole 9 is opened inside the positioning plate 8. An installation plate 10 is movably connected between the two positioning plates 8. An installation hole 11 is opened on both sides of the installation plate 10. A positioning spring 12 is fixedly connected inside the installation hole 11. A positioning block 13 is fixedly connected to the other end of the positioning spring 12. A U-shaped sleeve 14 is fixedly connected to the top of the installation plate 10. A screw 15 is movably connected inside one end of the U-shaped sleeve 14. A limiting ball 16 is fixedly connected to the bottom end of the screw 15. By limiting the piston block 6 with the limiting ball 16, quantitative extraction of reagents can be achieved. The height of the limiting ball 16 can be adjusted, thus making it suitable for various quantitative sampling needs and improving the applicability of the reagent sampling device.

[0028] A limiting plate 7 is fixedly connected to the outer wall of the piston rod 3, and four limiting plates 7 are fixedly installed on the outer wall of the piston rod 3 in a circumferential array to facilitate the movement of the piston rod 3. A through groove 5 is opened inside the handle 4, and the position of the through groove 5 corresponds to the position of the U-shaped sleeve 14, which facilitates the disassembly of the U-shaped sleeve 14 and the mounting plate 10 and prevents the handle 4 from affecting the disassembly of the U-shaped sleeve 14 and the mounting plate 10. The shape and size of the piston block 6 are matched with the shape and size of the sampling tube 1, and the piston block 6 is slidably connected to the inner wall of the sampling tube 1, which facilitates the sliding of the piston block 6 and thus facilitates the extraction of reagents. The diameter of the mounting hole 11 is larger than the diameter of the positioning block 13, and the positioning block 13 is slidably connected to the mounting hole 11 under the action of the positioning spring 12, which facilitates the retraction of the positioning block 13 into the mounting hole 11, thereby disconnecting the positioning block 13 from the positioning hole 9. The positioning block 13 is connected to the positioning hole 9, which facilitates the disassembly of the mounting plate 10. The shape and size of the positioning block 13 match the shape and size of the positioning hole 9. The positioning block 13 is movably connected to the positioning hole 9 under the action of the positioning spring 12. The positioning block 13 is correspondingly connected to the positioning hole 9 under the elastic force of the positioning spring 12, thereby completing the fixation of the position of the mounting plate 10. The outer wall of the screw 15 is provided with external threads, and the inner wall of the U-shaped sleeve 14 is provided with internal threads. The external threads on the screw 15 and the internal threads on the inner wall of the U-shaped sleeve 14 cooperate with each other, which facilitates the adjustment of the position of one end of the screw 15 inside the U-shaped sleeve 14, thereby adjusting the height of the limiting ball 16. The U-shaped sleeve 14 is made of transparent material, and the outer wall of the U-shaped sleeve 14 is engraved with scale lines, which facilitates the observation of the position of one end of the screw 15 inside the U-shaped sleeve 14, thereby facilitating the adjustment of the height of the limiting ball 16.

[0029] Working principle: When extracting reagent, determine the dosage of reagent to be extracted, press the positioning blocks 13 on both sides of the positioning plate 8 by hand, so that they compress the positioning spring 12 and retract into the mounting hole 11, thereby disconnecting the connection between the positioning block 13 and the positioning hole 9. Pull upward to remove the mounting plate 10. After removing the mounting plate 10, since one end of the screw 15 is located inside the U-shaped sleeve 14, and the inner wall of the U-shaped sleeve 14 is provided with internal threads, rotating the screw 15 can adjust the position of one end of the screw 15 inside the U-shaped sleeve 14. The U-shaped sleeve 14 is made of transparent material and has scale lines engraved on its surface. Adjust the position of one end of the screw 15 inside the U-shaped sleeve 14 according to the dosage of reagent to be extracted and the scale lines, and the height of the limiting ball 16 can be adjusted.

[0030] Insert one end of the U-shaped sleeve 14 with the limiting ball 16 into the sampling tube 1, and align the position of the mounting plate 10 with the position of the positioning plate 8 on the outer wall of the sampling tube 1. Press the positioning blocks 13 on both sides of the mounting plate 10 again to retract them into the mounting hole 11 and compress the positioning spring 12. Insert the bottom end of the mounting plate 10 between the two positioning plates 8 from top to bottom. When the positioning block 13 corresponds to the positioning hole 9, under the elastic force of the positioning spring 12, the positioning block 13 and the positioning hole 9 are connected, thereby fixing the mounting plate 10 and fixing the height of the limiting ball 16. Insert the sampling head 2 into the reagent bottle, and pull the handle 4 upward to move the piston rod 3 to extract the reagent. When the top of the piston block 6 moves to the bottom of the limiting ball 16, the limiting ball 16 abuts against the piston block 6, preventing it from moving, thus completing the quantitative extraction of the reagent.

[0031] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
