[0046] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0047] The reagent tube for detection equipment of the present invention will be described below with reference to the accompanying drawings.

[0048] like Figures 1 to 4As shown, the utility model provides a reagent tube for a detection device, which includes a dripper assembly 10, a tube body assembly 20 and a pressing assembly 30. The tube body assembly 20 includes a vesicle body 21 and a main body 22 for containing liquid. The first end of the main body 22 is connected to the dripper assembly 10, and the second end of the main body 22 is formed with a mounting groove 221. The bottom wall of the mounting groove 221 is provided with a through hole 222 that is connected to the inner cavity of the main body 22. The vesicle body 21 is arranged in the mounting groove 221 and corresponds to the through hole 222; the pressing assembly 30 includes a pressing cover 31 and an elastic reset member 32. The pressing cover 31 is provided at the second end of the main body 22 and is used to squeeze the vesicle body 21. The two ends of the elastic reset member 32 are respectively in one-to-one contact with the bottom wall of the mounting groove 221 and the pressing cover 31.

[0049] Specifically, the inner cavity of the main body 22 is used to accommodate liquids such as reagents or samples. The mounting groove 221 is connected to the inner cavity of the main body 22 through the through hole 222. The vesicle body 21 is arranged at the through hole 222. The pressing cover 31 is movably arranged at the second end of the main body 22 and is used to squeeze the vesicle body 21 toward the through hole 222. The elastic reset member 32 is arranged in the mounting groove 221 and is located between the bottom wall of the mounting groove 221 and the pressing cover 31. When pipetting is required, the operator presses the pressing cover 31, so that the pressing cover 31 squeezes the vesicle body 21 toward the through hole 222. The deformation of the vesicle body 21 increases the air pressure in the inner cavity of the main body 22, and the liquid contained in the inner cavity of the main body 22 can be discharged outward through the dripper assembly 10. In addition, when the pressing cover 31 squeezes the vesicle body 21 toward the through hole 222, it cooperates with the bottom wall of the mounting groove 221 to squeeze the elastic reset member 32. The elastic restoring force of the elastic reset member 32 acts on the pressing cover 31, so that the operator's pressing force needs to overcome the elastic force of the elastic reset member 32, which increases the pressing feel; further, the operator releases the pressing on the pressing cover 31 after the pressing is completed, and the elastic restoring force of the elastic reset member 32 acts on the pressing cover 31, so that the pressing cover 31 is quickly reset, and the reset feedback is fast and direct, which is convenient for the operator to accurately judge the liquid volume, improves the user experience, and improves the detection accuracy.

[0050] In an embodiment of the present utility model, the pressing cover 31 includes a cover body 311 and a pressing column 312. The cover body 311 is movably arranged in the mounting groove 221, and a receiving groove 3111 is formed on the side of the cover body 311 facing the mounting groove 221. The pressing column 312 is arranged in the receiving groove 3111 and corresponds to the vesicle body 21. The two ends of the elastic return member 32 are respectively in one-to-one contact with the bottom wall of the mounting groove 221 and the bottom wall of the receiving groove 3111.

[0051] like Figures 2 to 6The closure 311 is provided with a chute 312 which is in communication with the closure 311 and the chute 312. The chute 312 is pressed against the closure 311 and the chute 312 is pressed against the closure 311. The vesicle body 21 is pressed to discharge the liquid outward through the dripper assembly 10. In addition, when the operator presses the cover body 311, the bottom wall of the accommodating groove 3111 and the bottom wall of the mounting groove 221 cooperate to squeeze the elastic reset member 32. The pressing force overcomes the elastic force of the elastic reset member 32, and the pressing feel is obvious. The elastic recovery force of the elastic reset member 32 can act on the cover body 311, causing the cover body 311 to quickly rebound and reset. The reset feedback is timely, making it easier for the operator to judge the amount of liquid discharged. In addition, the operator can also judge the amount of liquid discharged by the pressing stroke of the cover body 311, realizing quantitative liquid discharge from the reagent tube, further improving the accuracy of the liquid discharge and the accuracy of the test results.

[0052] In the embodiment of the present invention, a first limiting flange 2211 is formed on the side wall of the installation groove 221, a second limiting flange 3112 is formed on the outer side of the cover body 311, and the second limiting flange 3112 is located between the bottom wall of the installation groove 221 and the first limiting flange 2211. Figures 2 to 6 As shown, the first limiting flange 2211 is arranged at the slot of the mounting groove 221 and protrudes toward the mounting groove 221, and the second limiting flange 3112 is arranged at the outer edge of the cover body 311. The elastic reset member 32 pushes the cover body 311 to reset after the operator releases the pressure on the cover body 311, so that the cover body 311 rebounds quickly. The first limiting flange 2211 is used to abut against the second limiting flange 3112 when the cover body 311 rebounds to prevent the cover body 311 from falling out of the mounting groove 221, thereby improving the structural stability.

[0053] Furthermore, the elastic return member 32 is configured as a spring 32a; a first limiting ring 2212 is formed on the bottom wall of the installation groove 221, and the first limiting ring 2212 is arranged around the outside of the vesicle body 21, and the end of the spring 32a that abuts against the bottom wall of the installation groove 221 is sleeved on the first limiting ring 2212; a second limiting ring 3113 is formed on the bottom wall of the accommodating groove 3111, and the second limiting ring 3113 is arranged around the outside of the pressing column 312, and the end of the spring 32a that abuts against the bottom wall of the accommodating groove 3111 is sleeved on the second limiting ring 3113.

[0054] like Figures 2 to 6As shown, the elastic return member 32 can adopt the spring 32a in the prior art, one end of the spring 32a extends into the mounting groove 221 and is located between the groove side wall of the mounting groove 221 and the first limiting ring 2212, and the other end of the spring 32a extends into the accommodating groove 3111 and is located between the groove side wall of the mounting groove 221 and the second limiting ring 3113. The first limiting ring 2212 and the second limiting ring 3113 both play the role of limiting the spring 32a and providing the spring 32a for installation, effectively preventing the spring 32a from shifting during the pressing and resetting process, improving feedback stability, and facilitating the installation of the spring 32a. It can be understood that the elastic return member 32 of the embodiment of the utility model is not limited to the spring 32a. The elastic return member 32 can also be set as an elastic return cylinder, elastic return ring or elastic return ring with elastic deformation function.

[0055] In an embodiment of the present utility model, the main body 22 includes a tube body portion 223 and a partition portion 224. The first end of the tube body portion 223 is connected to the dripper assembly 10. The partition portion 224 is arranged in the tube body portion 223 and is located at the second end of the tube body portion 223. The side of the partition portion 224 facing the dripper assembly 10 is used to accommodate liquid. The side of the partition portion 224 facing away from the dripper assembly 10 forms an installation groove 221, and a through hole 222 is opened on the partition portion 224.

[0056] like Figures 2 to 5 As shown, the inner cavity of the main body 22 is used to accommodate liquid, and the partition 224 is arranged in the main body 22 to divide the inner cavity of the main body 22 to form a mounting groove 221. The partition 224 is set as the bottom wall of the mounting groove 221. The partition 224 is provided with a through hole 222 connected to the inner cavity of the main body 22. The vesicle body 21 is arranged in the mounting groove 221 and connected to the partition 224, and the side of the vesicle body 21 facing the through hole 222 is formed with an extrusion cavity 211 connected to the through hole 222. When pipetting is required, the operator presses the cover body 311, causing the cover body 311 to drive the pressing column 312 to move toward the vesicle body 21, thereby causing the pressing column 312 to squeeze the vesicle body 21 toward the through hole 222. The vesicle body 21 is squeezed, causing the volume of the squeezing cavity 21 to decrease, and the internal air pressure of the main body 22 to increase, so that the liquid can be discharged outward through the dripper assembly 10. The operator controls the amount of liquid discharged from the dripper assembly 10 by controlling the pressing stroke of the cover body 311, thereby achieving quantitative pipetting of the reagent tube and facilitating the operator to judge the amount of liquid discharged. In addition, when the operator presses the cover body 311 to perform pipetting, the pressing force needs to overcome the elastic force of the elastic reset member 32, and the pressing feel is obvious. The elastic reset member 32 can quickly push the cover body 311 to rebound and reset, and the reset feedback is timely, which improves the user experience.

[0057] In the embodiment of the present invention, the dripper assembly 10 includes a dripper body 11 and a protective cover 12. The first end of the main body 22 is detachably connected to one end of the dripper body 11, and the protective cover 12 is detachably covered on the other end of the dripper body 11. Figures 1 to 4 As shown, the dripper body 11 and the main body 22 are detachably connected to facilitate the operator to add liquids such as reagents or samples into the main body 22, and the protective cover 12 is used to be detachably sleeved on the outer peripheral side of the dripper body 11 to seal the liquid outlet of the dripper body 11, effectively preventing liquid leakage and improving the sealing of the reagent tube.

[0058] Furthermore, the dripper body 11 includes a connecting section 111 and a liquid outlet section 112. The first end of the main body 22 extends into the connecting section 111 and is detachably connected to the connecting section 111. The liquid outlet section 112 is connected to the connecting section 111, and the liquid outlet section 112 extends into the protective cover 12 and is detachably connected to the protective cover 12. Figures 1 to 4 and Figure 7 As shown, the connecting section 111 is used for the first end of the main body 22 to extend into and to be threadedly connected to the first end of the main body 22, and the protective cover 12 is used for the liquid outlet section 112 to extend into and to be threadedly connected to the liquid outlet section 112. The threaded connection between the main body 22 and the connecting section 111 and the threaded connection between the liquid outlet section 112 and the protective cover 12 are convenient for disassembly and assembly and improve the sealing effect.

[0059] In the embodiment of the present utility model, the connecting section 111 includes a connecting portion 1111 and a transition portion 1112. The connecting portion 1111 is connected to the transition portion 1112 and forms a limiting step 1113. The first end of the main body 22 extends into the connecting portion 1111 and is detachably connected to the connecting portion 1111. The first end of the main body 22 abuts against the limiting step 1113. The liquid outlet section 112 is connected to the end of the transition portion 1112 away from the connecting portion 1111. Figures 1 to 4 and Figure 7 As shown, a limiting step 1113 for abutting against the main body 22 is formed between the connecting portion 1111 and the adapter portion 1112. When the first end of the main body 22 is inserted into the connecting portion 1111 and threadedly connected to the connecting portion 1111, the limiting step 1113 is used to limit the screw-in depth of the main body 22. In addition, the connecting section 111 also includes a stop portion 1114. The stop portion 1114 is provided on the limiting step 1113 and spaced apart from the connecting portion 1111. The stop portion 1114 is used to adhere to the inner wall of the main body 22 and extend into the inner cavity of the main body 22. The connecting portion 1111 is surrounded by the outside of the main body 22. By providing the stop portion 1114, the liquid in the inner cavity of the main body 22 can be directly introduced into the inner cavity of the adapter portion 1112, thereby avoiding liquid leakage and contamination of reagents or samples.

[0060] Furthermore, a limiting boss 2231 is formed on the outer side of the main body 22, and the end of the connecting section 111 away from the liquid outlet section 112 abuts against the limiting boss 2231. Figures 1 to 4 and Figure 7 As shown, the limiting boss 2231 is provided on the outer periphery of the main body 22 and is used to abut against the connecting portion 1111. When the first end of the main body 22 is inserted into the connecting portion 1111 and is threadedly connected to the connecting portion 1111, the limiting boss 2231 is used to limit the screw-in depth of the main body 22, and the limiting boss 2231 abuts against the connecting portion 1111 for easy observation by the operator, so as to prompt the operator that the main body 22 is installed in place, effectively preventing loose connection from causing liquid leakage or excessive screwing from causing thread damage.

[0061] In the embodiment of the present utility model, Figure 4 As shown, a sealing protrusion 121 for extending into the liquid outlet section 112 is formed in the protective cover 12. When the protective cover 12 is put on the outside of the liquid outlet section 112 and is threadedly connected to the liquid outlet section 112, the sealing protrusion 121 can extend into the liquid outlet section 112 and fit against the inner wall of the liquid outlet section 112, further strengthening the sealing of the reagent tube and effectively preventing liquid leakage.
