Thus, after the reagent container 10 is pierced and the liquid reagent flows into the transition cavity 71, the at least one circle of third flange 61 is in interference fit with the wall of the transition cavity 71, so that the reagent container has better sealing performance and can prevent the liquid reagent in the transition cavity 71 from flowing out through the insertion port 711.
Referring to fig. 13, further, a groove 123 is disposed around the outer wall of the second end 12, and the elastic sleeve 60 is disposed in the groove 123. A third flange 61 is provided on the outer wall of the elastic sleeve 60. Particularly, in order to guarantee the sealing effect, the elastic sleeve 60 is soft rubber with good elasticity, such as TPE soft rubber, silica gel, rubber and the like, and is not limited herein and can be set according to actual requirements.
Referring to fig. 3 to 8, fig. 6 is a sectional view of a frame 90 of a reagent transferring apparatus according to an embodiment of the present invention in a second working position, fig. 7 is an enlarged structural view of fig. 6 at C, and fig. 8 is an enlarged structural view of fig. 6 at D. In one embodiment, the reagent transfer device further comprises a frame 90. The reagent vessel 10 is disposed on the frame 90. The frame 90 is adjustably arranged on the support 70, and the frame 90 is provided with a first working position and a second working position; when the frame 90 is in the first working position, a space is provided between the second sealing membrane 50 and the piercing member 72; when the frame 90 is subjected to an external driving force greater than the preset force, the frame 90 moves from the first working position to the second working position under the action of the external driving force, and the second sealing membrane 50 is punctured by the puncturing piece 72 when the frame 90 moves to the second working position. The specific magnitude of the preset force is set according to actual conditions, and is not limited herein. Before the reagent container 10 is not punctured, the frame 90 is in the first working position, the frame 90 supports the reagent container 10 so that a space is formed between the second sealing membrane 50 of the reagent container 10 and the puncturing member 72, therefore, the second sealing membrane 50 cannot be punctured because the puncturing member 72 does not contact the second sealing membrane 50, and the frame 90 needs to be moved from the first working position to the second working position when an external driving force is greater than a preset force, namely, the frame is always in the first working position when the external driving force is smaller than the preset force, so that the sealing membrane of the reagent container 10 can be prevented from being punctured in the assembling process and the transportation process of the reagent transfer device; when the first sealing film 20 and the second sealing film 50 of the reagent container 10 need to be punctured, the needle puncturing piece 40 is driven to move, and the needle puncturing piece 40 presses against the soft piece 31 and the first sealing film 20, on one hand, the first sealing film 20 is punctured by the needle puncturing piece 40, on the other hand, the cover body 30, the reagent container 10 and the frame 90 are pushed by the soft piece 31 to move towards the support 70 when the needle puncturing piece 40 moves, so that the frame 90 is driven by an external driving force to be larger than a preset force, the frame 90 moves from the first working position to the second working position under the action of the external driving force, and the puncturing piece 72 punctures the second sealing film 50 when the frame 90 moves to the second working position.
Referring to fig. 3 to 5, further, a supporting pillar 73 is disposed on the supporting seat 70, a limiting block 91 corresponding to the supporting pillar 73 is disposed on the frame 90, and when the frame 90 is located at the first working position, the limiting block 91 abuts against the supporting pillar 73.
Referring to fig. 3 to 5, in an embodiment, the stopper 91 includes a guide sleeve 911 and a breakable portion 912 disposed at one end of the guide sleeve 911. The supporting column 73 is movably disposed in the guide sleeve 911 and abuts against the breakable portion 912, and when the frame 90 receives an external driving force greater than a preset force, the breakable portion 912 is broken and moves out of the guide sleeve 911 by the supporting column 73. In this way, the frame 90 and the reagent container 10 thereon move from the first operating position to the second operating position in the process of the support column 73 breaking the breakable portion 912 and moving it out of the guide sleeve 911. When the reagent vessel 10 is moved into the second operating position, the piercing member 72 pierces the second sealing membrane 50.
It should be noted that there are many specific design forms of the breakable portion 912, as long as when the frame 90 receives an external driving force greater than a preset force, the support pillar 73 can break the breakable portion 912 and move out of the guide sleeve 911; in addition, when the frame 90 is subjected to an external driving force not greater than a predetermined force, the supporting posts 73 abut against the breakable portions 912, thereby supporting the frame 90 and the reagent containers 10 thereon. For example, the breakable part 912 is a limiting piece arranged at one end of the guide sleeve 911, the edge of the limiting piece is connected with the guide sleeve 911 through at least one breakable strip, when the acting force of the support column 73 on the limiting piece reaches a set value, the breakable strip is broken, the limiting piece is separated from the guide sleeve 911, and thus the support column 73 can break the breakable part 912 and move out of the guide sleeve 911; for another example, the breakable portion 912 is a film, a brittle glass, an easy-to-draw cardboard, or the like fixed to one end of the guide sleeve 911, and when the breakable portion 912 is acted by the support column 73 to reach a set value, the support column 73 can break the breakable portion 912 and move out of the guide sleeve 911.
In another embodiment, the limiting block 91 and the supporting column 73 are not limited to the limiting piece and the breakable portion 912 in the above embodiments, for example, at least one of the limiting block 91 and the supporting column 73 is an elastic block, and when the frame 90 reaches a predetermined force by an external driving force, the limiting block 91 and the supporting block can be deformed and compressed enough to move the frame 90 and the reagent container 10 thereon from the first working position to the second working position, and when the reagent container 10 moves to the second working position, the second sealing film 50 is broken by the breaking member 72. For another example, the limiting block 91 is abutted against the supporting column 73 through an elastic block, and similarly, when the frame 90 reaches a preset force by an external driving force, the elastic block can be deformed and compressed enough to move the frame 90 and the reagent container 10 thereon from the first working position to the second working position, and when the reagent container 10 moves to the second working position, the second sealing film 50 is pierced by the piercing member 72.
As an alternative, the arrangement of the supporting column 73 and the limiting block 91 may be reversed, that is, the supporting column 73 is disposed on the frame 90, and the limiting block 91 is disposed on the support 70.
Referring to fig. 2, in an embodiment, there are at least three supporting columns 73, at least three limiting blocks 91, and the three supporting columns 73 and the three limiting blocks 91 are disposed in a one-to-one correspondence. So, support conflict in at least three stopper 91 through at least three support column 73 corresponds respectively, can realize that frame 90 sets up on support 70 steadily.
It should be noted that the number of the supporting columns 73 may be one, two or another, and is not limited herein. Likewise, the limiting blocks 91 may be one, two or another number, which is not limited herein.

Referring to fig. 2 and 3, in one embodiment, the number of the reagent containers 10 is several, and several reagent containers 10 are connected in sequence. The cover 30 covers the first ends 11 of the plurality of reagent containers 10, and the soft material 31 covers the first openings 111 of the plurality of reagent containers 10.
Referring to fig. 11-13, in one embodiment, the reagent transfer device further includes a support 80. The supporting member 80 is disposed at the first end 11, and the supporting member 80 is provided with a relief hole 81, the relief hole 81 is disposed opposite to the puncturing position of the puncturing member 40, and the supporting member 80 is configured to support and abut against the first sealing film 20. In this way, in the process of puncturing the first sealing membrane 20 by pressing the puncturing member 40 downwards, the supporting member 80 can support and abut against the first sealing membrane 20, and the avoiding hole 81 which can avoid the puncturing member 40 is formed in the supporting member 80, so that the movement stroke of the puncturing member 40 when the first sealing membrane 20 is punctured is reduced, and the effect of puncturing the first sealing membrane 20 is improved more obviously. Therefore, the sealing film can be conveniently punctured, the possibility that the sealing film is not punctured is greatly reduced, and the puncturing effect of the first sealing film 20 is better.
Referring to fig. 11 to 13, further, a step 112 is disposed on the opening wall of the first opening 111, and the supporting member 80 is disposed on the step 112. Thus, in the production process of the reagent vessel 10, the supporting member 80 is mounted on the step 112, and the first sealing film 20 mounted at the first end 11 positions the supporting member 80, so that the assembling operation of the reagent vessel 10 is convenient. In addition, when the support member 80 is mounted on the step 112, the upper surface of the support member 80 is substantially flush with the end surface of the first end 11, which ensures the sealability of the first sealing film 20 to the first opening 111.
The supporting member 80 is not limited to be disposed on the first end 11 by being mounted on the step 112, but the supporting member 80 may be disposed on the first end 11 by other methods, for example, by being fixed to the first end 11 by mounting members such as screws, pins, rivets, clips, etc., or may be fixed to the first end 11 by being bonded, welded, etc., or the supporting member 80 and the first end 11 may be integrated, and the method is not limited herein and may be disposed according to actual requirements.
Referring to fig. 11 to 13, further, the supporting member 80 is a baffle plate disposed on the step 112, and the avoiding hole 81 is disposed in a middle portion of the baffle plate. In this way, when the pricking member 40 is pressed down to pierce the first sealing film 20, the pricking member generally acts on the middle portion of the first sealing film 20 to achieve a better pricking effect on the first sealing film 20, and accordingly, the avoiding hole 81 is disposed at the middle portion of the baffle plate, so that the avoiding hole 81 can smoothly avoid the pricking member 40. Of course, if the needle-punching member 40 is pushed down to puncture other portions of the first sealing film 20, such as the outer peripheral portion, the relief hole 81 is provided in the outer peripheral portion of the barrier.
In one embodiment, the first end 11 is the top end of the reagent vessel 10 and the second end 12 is the bottom end of the reagent vessel 10. Further, the opening size of the second opening 121 is smaller than the opening size of the first opening 111. Wherein the opening size of the second opening 121 is small, the second sealing membrane 50 on the second opening 121 is easily pierced by the piercing member 72 on the bottom wall of the second chamber, so that it may not be necessary to provide the support member 80 at the first opening 111 similarly to the first end 11. That is, the support member 80 does not need to be disposed on the second end 12, and the support member 80 may be disposed, but is not limited thereto.
