[0044] The following details the specific implementation manners of the present utility model with reference to the drawings. It should be understood that the specific implementation manners described herein are only for explaining and understanding the present utility model, and are not used to limit the present utility model.

[0045] The reagent tube for a detection device of the present utility model is described below with reference to the drawings.

[0046] As Figures 1 to 4As shown in the figure, the present utility model provides a reagent tube for a detection device. The reagent tube for the detection device includes a dropper assembly 10, a tube body assembly 20, and a pressing cover 30. The tube body assembly 20 includes a vesicle body 21 and a main tube body 22 for accommodating liquid. The first end of the main tube body 22 is connected to the dropper assembly 10, and the vesicle body 21 is arranged at the second end of the main tube body 22; the pressing cover 30 includes an installation cylinder 31, a pressing column 32, and an elastic body 33. The installation cylinder 31 is arranged at the second end of the main tube body 22. The pressing column 32 is movably inserted through the installation cylinder 31 and is correspondingly arranged with the vesicle body 21. The elastic body 33 is arranged inside the installation cylinder 31, and both ends of the elastic body 33 are respectively and correspondingly connected to the inner wall of the installation cylinder 31 and the pressing column 32.

[0047] Specifically, the inner cavity of the main tube body 22 is used to accommodate liquids such as reagents or samples. The dropper assembly 10 and the vesicle body 21 are respectively arranged at both ends of the main tube body 22. The installation cylinder 31 is arranged at the second end of the main tube body 22, and the vesicle body 21 is located inside the installation cylinder 31. The pressing column 32 is movably arranged inside the installation cylinder 31 and is used to squeeze the vesicle body 21. The elastic body 33 is arranged between the inner wall of the installation cylinder 31 and the pressing column 32, and one end of the elastic body 33 is connected to the inner wall of the installation cylinder 31, and the other end is connected to the pressing column 32.

[0048] When pipetting is required, the operator presses the pressing column 32, causing the pressing column 32 to move towards the vesicle body 21 and squeeze the vesicle body 21. The vesicle body 21 deforms, increasing the air pressure in the inner cavity of the main tube body 22. The liquid contained in the inner cavity of the main tube body 22 can be discharged outward through the dropper assembly 10. Moreover, when the pressing column 32 moves towards the vesicle body 21, it cooperates with the inner wall of the installation cylinder 31 to stretch the elastic body 33. The elastic restoring force of the elastic body 33 acts on the pressing column 32, so that the pressing force of the operator needs to overcome the elastic force of the elastic body 33, increasing the pressing feel. It is convenient for the operator to judge whether the vesicle body 21 is squeezed in place according to the moving stroke of the pressing column 32, improving the accuracy of quantitative liquid discharge.

[0049] It can be understood that after the operator finishes pressing and releases the pressing on the pressing column 32, the elastic restoring force of the elastic body 33 acts on the pressing column 32, causing the pressing column 32 to move away from the vesicle body 21 and quickly reset. The reset feedback is fast and direct, which is convenient for the operator to accurately judge the liquid discharge volume, improving the use experience and the detection accuracy.

[0050] In the embodiment of the present utility model, the elastic body 33 includes an extension part 331, a first connection part 332, and a second connection part 333. The extension part 331 surrounds the outside of the pressing column 32. The first connection part 332 and the second connection part 333 are respectively arranged at both ends of the extension part 331. The first connection part 332 is connected to the inner wall of the installation cylinder 31, and the second connection part 333 is connected to the pressing column 32.

[0051] As Figure 4 and Figure 5 shown, the first connecting portion 332 is bent from the extending portion 331 toward the inner wall of the mounting cylinder 31 and connected to the inner wall of the mounting cylinder 31. The second connecting portion 333 is bent from the extending portion 331 toward the pressing column 32 and connected to the pressing column 32. An operator presses the pressing column 32 in the direction of the vesicle body 21. The pressing column 32 stretches the extending portion 331 through the first connecting portion 332 and overcomes the elastic force. The pressing feedback feel is obvious, enabling the operator to judge the extrusion degree of the vesicle body 21 according to the moving stroke of the pressing column 32 and the pressing feedback, facilitating the operator to accurately judge the liquid output volume, and improving the accuracy of the detection result.

[0052] Moreover, the extending portion 331 is arc-shaped and surrounds the outside of the pressing column 32, increasing the length dimension of the extending portion 331. Furthermore, the elastic deformation amount of the extending portion 331 and the moving stroke of the pressing column 32 are increased, further enhancing the pressing feel. The first connecting portion 332 and the second connecting portion 333 are respectively bent from both ends of the extending portion 331 and connected to the mounting cylinder 31 and the pressing column 32 respectively, improving the connection strength and extending the service life of the elastic body 33.

[0053] In the embodiment of the present utility model, the main body 22 includes a tube portion 221 and a mounting portion 222. The two ends of the tube portion 221 are respectively connected to the dropper assembly 10 and the mounting portion 222 in a one-to-one correspondence. The vesicle body 21 is arranged at one end of the mounting portion 222 away from the tube portion 221. The mounting cylinder 31 is sleeved on the mounting portion 222 and extends out of the mounting portion 222. As Figure 2 and Figure 3 shown, one end of the mounting cylinder 31 is sleeved on the mounting portion 222, and the other end of the mounting cylinder 31 extends out of the mounting portion 222. The vesicle body 21 is located inside the mounting cylinder 31, and the pressing column 32 passes through the mounting cylinder 31 and is used to squeeze the vesicle body 21 to achieve quantitative liquid output. By sleeving the mounting cylinder 31 on the mounting portion 222, the pressing cover 30 can be quickly installed on the main body 22. The assembly is convenient and fast, and the pressing cover 30 is easy to manufacture, reducing the production cost and being suitable for mass production.

[0054] Furthermore, a first positioning protrusion 2221 is formed on the outer side of the mounting portion 222, and a first positioning groove 311 for the first positioning protrusion 2221 to extend into is opened on the inner wall of the mounting cylinder 31. As Figure 3 and Figure 7As shown, the first positioning protrusion 2221 is provided on the outer side of the installation part 222. A first positioning groove 311 is formed in the inner wall of the installation cylinder 31 at a position corresponding to the first positioning protrusion 2221. The installation cylinder 31 is sleeved on the installation part 222 so that the first positioning protrusion 2221 is clamped in the first positioning groove 311 and cooperates with the first positioning groove 311 to limit the installation cylinder 31, effectively preventing the installation cylinder 31 from loosening. Moreover, in a preferred embodiment of the present utility model, both the first positioning protrusion 2221 and the first positioning groove 311 are annularly arranged, improving the connection strength and assembly stability between the installation cylinder 31 and the installation part 222.

[0055] In an embodiment of the present utility model, a first positioning step 223 is formed between the installation part 222 and the pipe body part 221. One end of the installation cylinder 31 facing the pipe body part 221 abuts against the first positioning step 223. As Figure 3 and Figure 7 shown, the first positioning step 223 is provided between the installation part 222 and the pipe body part 221. The first positioning step 223 is used to abut against the installation cylinder 31 for the convenience of the operator to observe, so as to prompt the operator that the installation cylinder 31 is installed in place, further improving the assembly convenience.

[0056] In an embodiment of the present utility model, the vesicle body 21 includes a vesicle part 211 and a sleeved part 212. The vesicle part 211 is provided on the sleeved part 212. A second positioning step 2222 is formed on the installation part 222. The sleeved part 212 is sleeved on the installation part 222 and abuts against the second positioning step 2222. As Figure 3 、 Figure 6 and Figure 7 shown, the second positioning step 2222 is provided at one end of the installation part 222 away from the pipe body part 221. The sleeved part 212 can be sleeved on the installation part 222. The second positioning step 2222 is used to abut against the sleeved part 212 for the convenience of the operator to confirm that the vesicle body 21 is installed in place. The assembly is convenient and fast. The vesicle part 211 is provided on the sleeved part 212, and an extrusion cavity communicating with the inner cavity of the main pipe body 22 is formed on one side of the vesicle part 211 facing the main pipe body 22.

[0057] When pipetting is required, the operator presses the pressing column 32, so that the pressing column 32 moves towards the vesicle part 211 and squeezes the vesicle part 211. The vesicle part 211 is squeezed, so that the volume of the extrusion cavity decreases, and the internal air pressure of the main pipe body 22 increases, and the liquid can be discharged outward through the drip head assembly 10. The operator controls the pressing stroke of the pressing column 32 to control the liquid discharge amount of the drip head assembly 10, realizing quantitative pipetting of the reagent tube and facilitating the operator to judge the liquid discharge amount. Moreover, when the operator presses the pressing column 32, the pressing force needs to overcome the elastic force of the elastic body 33. The pressing feel is obvious. The elastic body 33 can quickly pull the pressing column 32 to rebound and reset, and the reset feedback is timely, improving the use experience.

[0058] In the embodiment of the present utility model, a second positioning protrusion 2121 is formed on the inner side of the sleeved part 212, and a second positioning groove 2223 for the second positioning protrusion 2121 to extend into is formed on the outer side of the mounting part 222. As Figure 3 , Figure 6 and Figure 7 shown, the second positioning protrusion 2121 is arranged on the inner side of the sleeved part 212, the second positioning groove 2223 corresponding to the position of the second positioning protrusion 2121 is formed on the outer side of the mounting part 222, the sleeved part 212 is sleeved on the mounting part 222 so that the second positioning protrusion 2121 is clamped in the second positioning groove 2223 and cooperates with the second positioning groove 2223 to limit the sleeved part 212, effectively preventing the vesicle body 21 from loosening. Moreover, in the preferred embodiment of the present utility model, both the second positioning protrusion 2121 and the second positioning groove 2223 are annularly arranged, improving the connection strength and assembly stability between the vesicle body 21 and the mounting part 222.

[0059] Furthermore, a positioning boss 2224 is formed at one end of the mounting part 222 away from the tube body part 221, and a third positioning groove 2122 for the positioning boss 2224 to extend into is formed on the sleeved part 212. As Figure 3 , Figure 6 and Figure 7 shown, a positioning boss 2224 protrudes upward at one end of the mounting part 222 away from the tube body part 221, the third positioning groove 2122 corresponding to the position of the positioning boss 2224 is formed inside the sleeved part 212, the sleeved part 212 is sleeved on the mounting part 222 so that the positioning boss 2224 is clamped in the third positioning groove 2122 and cooperates with the third positioning groove 2122 to limit the sleeved part 212, playing a role in restricting the displacement of the vesicle body 21, and the structure is stable and reliable. Moreover, in the preferred embodiment of the present utility model, both the positioning boss 2224 and the third positioning groove 2122 are annularly arranged, improving the connection strength and assembly stability between the vesicle body 21 and the mounting part 222.

[0060] In the embodiment of the present utility model, a pressing cap 34 is provided on the pressing column 32, and the pressing cap 34 is located at one end of the pressing column 32 away from the vesicle body 21. As Figures 1 to 4As shown, one end of the pressing column 32 is located inside the mounting cylinder 31, and the other end extends out of the pressing column 32. The pressing column 32 can move along the extending direction of the mounting cylinder 31 and squeeze the vesicle part 211 located inside the mounting cylinder 31. A pressing cap 34 is provided at the end of the pressing column 32 outside the mounting cylinder 31. When pipetting is required, the operator presses the pressing cap 34 so that the pressing cap 34 pushes the pressing column 32 to move towards the vesicle part 211 and squeeze the vesicle part 211. The pressing column 32 stretches the elastic body 33 downward. The elastic restoring force of the elastic body 33 pulls the pressing column 32 to rebound, increasing the pressing feel. The pressing cap 34 can also be used to abut against the upper end of the mounting cylinder 31. When the operator presses the pressing cap 34 until it abuts against the mounting cylinder 31, the mounting cylinder 31 limits the movement of the pressing column 32 through the pressing cap 34. The operator can determine that the vesicle part 211 is squeezed in place through the collision feedback between the pressing cap 34 and the mounting cylinder 31, further improving the accuracy of quantitative liquid discharge.

[0061] In the embodiment of the present utility model, the number of the elastic bodies 33 is set to be multiple, and the multiple elastic bodies 33 are arranged at intervals along the circumferential direction of the pressing column 32. As Figure 4 and Figure 5 shown, the multiple elastic bodies 33 are all arranged inside the mounting cylinder 31 and spaced along the outer periphery of the pressing column 32. The first connecting portion 332 of each elastic body 33 is connected to the inner wall of the mounting cylinder 31, and the second connecting portion 333 of each elastic body 33 is connected to the pressing column 32. The pressing column 32 can synchronously drive the multiple elastic bodies 33 to undergo elastic deformation so that the multiple elastic bodies 33 can all provide pressing feedback to the operator, improving the pressing feel. And setting multiple elastic bodies 33 can play a role in guiding the movement of the pressing column 32, preventing the pressing column 32 from being stressed unilaterally and causing the moving direction to tilt, and improving the pressing smoothness.

[0062] In the embodiment of the present utility model, the drip head assembly 10 includes a drip head body 11 and a protective cover 12. The first end of the main pipe body 22 is detachably connected to one end of the drip head body 11, and the protective cover 12 is detachably covered on the other end of the drip head body 11. As Figure 1 and Figure 2 shown, the drip head body 11 is detachably connected to the main pipe body 22 to facilitate the operator to add liquids such as reagents or samples into the main pipe body 22. The protective cover 12 is used to detachably sleeve on the outer peripheral side of the drip head body 11 to block the liquid outlet of the drip head body 11, effectively preventing liquid leakage and improving the sealing performance of the reagent tube.
