The liquid taking mechanism 10 is used to transport the liquid in the reagent bag assembly 20 to flow out of the external object to be filled with liquid, or to transport the liquid into the reagent bag assembly 20.

[0043] In order to better explain the reagent kit 100 , a first direction x, a second direction y, and a third direction z that are perpendicular to each other are introduced.

[0044] For the above-mentioned liquid taking mechanism 10, please refer to Figure 2-Figure 6 The liquid extraction mechanism 10 includes a connecting plate 11, a puncture assembly 12, a housing 13, and a first locking member 14. The connecting plate 11 is disposed on the reagent bag assembly 20, the puncture assembly 12 is disposed on the housing 13, and the first locking member 14 is connected to the housing 13. The first locking member 14 is used to lock or unlock the connecting plate 11. When the first locking member 14 is locked to the connecting plate 11, the puncture assembly 12 is connected to the reagent bag assembly 20, and when the first locking member 14 is unlocked from the connecting plate 11, the puncture assembly 12 is separated from the reagent bag assembly 20.

[0045] For the above-mentioned connecting plate 11, see Figure 2-Figure 4 The connecting plate 11 is provided with a puncture through hole 11a, which penetrates the connecting plate 11 along a third direction, and the puncture through hole 11a is used for the insertion of the puncture component 12. The puncture through hole 11a and the hole opposite to the puncture component 12 are provided with a guide structure, which plays a guiding role and can quickly position the puncture component 12. The connecting plate 11 is also provided with a first locking through hole 11b, which penetrates the connecting plate 11 along a third direction z. The connecting plate 11 is also provided with a slide groove 11c. In this embodiment, the connecting plate 11 includes a plate body 111, a first extension portion 112 and a second extension portion 113, as shown in FIG. Figure 5 As shown, the plate body 111 is arranged on the reagent bag assembly 20, the first extension part 112 and the second extension part 113 are both L-shaped, the first extension part 112 and the second extension part 113 are arranged opposite to each other, the main body, the first extension part 112 and the second extension part 113 are jointly enclosed to form a slide groove 11c, and the slide groove 11c is connected to the puncture through hole 11a.

[0046] For the above-mentioned puncture assembly 12, please refer to Figure 3 The puncture assembly 12 includes a liquid collection needle 121 and a pipeline 122. The liquid collection needle 121 is connected to the pipeline 122, and the pipeline 122 is connected to the outside. The liquid collection needle 121 is installed in the shell 13, and part of the liquid collection needle 121 is accommodated in the shell cavity 13a, and the other part of the liquid collection needle 121 passes through the bottom wall of the shell cavity 13a along the third direction z and is exposed to the outer surface of the shell 13, and the liquid collection needle 121 exposed to the outer surface of the shell 13 is inserted into the puncture through hole 11a.

[0047] For the housing 13, see Figure 3 The housing 13 is provided with a housing cavity 13a and a first sliding hole 13b, and the first sliding hole 13b is connected to the housing cavity 13a. Optionally, the first sliding hole 13b passes through the side wall of the housing cavity 13a along the first direction x.

[0048] For the first locking member 14, see Figure 6 The first locking member 14 includes a first main body 141 and a first limiting portion 142. One end of the first main body 141 is connected to the housing 13, and the other end of the first main body 141 is connected to the first limiting portion 142. The first limiting portion 142 passes through the first locking through hole 11b and abuts against the opening of the first locking through hole 11b, so that the first limiting portion 142 and the housing 13 jointly clamp the connecting plate 11. It can be understood that along the plugging direction of the first limiting portion 142 or along the third direction z, the cross-sectional area of ​​the first limiting portion 142 is greater than the cross-sectional area of ​​the first main body 141, so that the first limiting portion 142 and the first main body 141 form a limiting step 145, and the limiting step 145 is used to abut against the opening of the first locking through hole 11b. When the first locking member 14 is inserted into the first locking through hole 11 b , after the first limiting portion 142 passes through the first locking through hole 11 b , the limiting step 145 abuts against the opening of the first locking through hole 11 b , and the limiting step 145 and the housing 13 clamp the connecting plate 11 together.

[0049] Optionally, along the plugging direction of the first limiting portion 142 or along the third direction z, the cross-sectional area of ​​the first limiting portion 142 gradually decreases, and when the first locking member 14 is plugged into the first locking through hole 11 b , the first locking member 14 has a guiding function.

[0050] Optionally, along the insertion direction of the first limiting portion 142 or along the third direction z, the cross-sectional area of ​​the end of the first limiting portion 142 close to the first body 141 is larger than the cross-sectional area of ​​the first locking through hole 11b, and the cross-sectional area of ​​the end of the first limiting portion 142 away from the first body 141 is smaller than the cross-sectional area of ​​the first locking through hole 11b. When the first locking member 14 is inserted into the first locking through hole 11b, the end of the first limiting portion 142 away from the first body 141 guides the first locking member 14 to be inserted into the first locking through hole 11b. As the first limiting portion 142 gradually passes through the first locking through hole 11b, the first limiting portion 142 undergoes elastic deformation to allow the first limiting portion 142 to pass through the first locking through hole 11b, until the limiting step 145 of the first locking member 14 abuts against the opening of the first locking through hole 11b, and the first limiting portion 142 performs a reset movement.

[0051] In some embodiments, in order to realize the detachability or convenient detachability of the first locking member 14 and the connecting plate 11, the first locking member 14 can be slidably disposed on the housing 13. Specifically, the cross-sectional area of ​​the first limiting portion 142 is smaller than the cross-sectional area of ​​the first locking through hole 11b; the first locking member 14 is also provided with a first pressing portion 143, such as Figure 6 As shown, the first pressing portion 143 is connected to the first body 141; the above-mentioned liquid taking mechanism 10 also includes an elastic member 15, such as Figure 3 As shown, one end of the elastic member 15 is connected to the housing 13, and the other end of the elastic member 15 is connected to the first pressing portion 143. When the first locking member 14 is located at the first preset position, the first limiting portion 142 abuts against the opening of the first locking through hole 11b, and when the first locking member 14 is located at the second preset position, the first limiting portion 142 is separated from the opening of the first locking through hole 11b. When no external force acts on the first pressing portion 143, the first locking piece 14 is located at the first preset position, and the first locking through hole 11b and the first locking piece 14 do not correspond to each other. When an external force acts on the first pressing portion 143, the first locking piece 14 moves from the first preset position to the second preset position, and the first locking through hole 11b corresponds to the first locking piece 14, that is, the first locking piece 14 is located above the first locking through hole 11b. When a force is applied along the third direction z, the first locking piece 14 is inserted into the first locking through hole 11b. When the external force stops being applied to the first pressing portion 143, the first locking piece 14 moves from the second preset position to the first preset position, and the limiting step 145 of the first locking piece 14 abuts against the hole opening of the first locking through hole 11b.

[0052] In some embodiments, the liquid extraction mechanism 10 further includes a limiter 16, such as Figure 3 One end of the limiter 16 is connected to the housing 13, and the other end of the limiter 16 corresponds to the first locking member 14. When the first locking member 14 is located at the second preset position, the other end of the limiter 16 abuts against the first locking member 14, and the first locking member 14 is not allowed to move toward the limiter 16. Optionally, the limiter 16 is sleeved on the elastic member 15, and the limiter 16 can reduce the risk of the elastic member 15 being offset.

[0053] In some embodiments, a second limiting portion 144 extends circumferentially from the first pressing portion 143. Figure 6 As shown, the second limiting portion 144 is used to abut against the opening of the first sliding hole 13 b and does not allow the locking member to move away from the limiting member 16 .

[0054] In some embodiments, the liquid extraction mechanism 10 further includes a second locking member 17, such as Figure 3-Figure 6 The second locking member 17 is connected to the housing 13 , and is used to lock or unlock the connecting plate 11 .

[0055] Optionally, one end of the elastic member 15 is connected to the second locking member 17, and the other end of the elastic member 15 is connected to the first locking member 14. Specifically, the connecting plate 11 is further provided with a second locking through hole 11d; the second locking member 17 includes a second main body 171 and a third limiting portion 172, one end of the second main body 171 is connected to the housing 13, and the other end of the second main body 171 is connected to the third limiting portion 172, and the third limiting portion 172 passes through the second locking through hole 11d and abuts against the opening of the second locking through hole 11d, so that the third limiting portion 172 and the housing 13 jointly clamp the connecting plate 11. It can be understood that along the plugging direction of the third limiting portion 172 or along the third direction z, the cross-sectional area of ​​the third limiting portion 172 is greater than the cross-sectional area of ​​the second main body 171, so that the third limiting portion 172 and the second main body 171 form a limiting step 175, and the limiting step 175 is used to abut against the opening of the second locking through hole 11d.

[0056] Optionally, along the plugging direction of the third limiting portion 172 or along the third direction z, the cross-sectional area of ​​the third limiting portion 172 gradually decreases, and when the second locking member 17 is plugged into the second locking through hole 11d, the second locking member 17 has a guiding function.

[0057] In some embodiments, in order to realize the detachability or convenient detachability of the second locking member 17 and the connecting plate 11, the second locking member 17 can be slidably disposed on the housing 13. Specifically, the cross-sectional area of ​​the third limiting portion 172 is smaller than the cross-sectional area of ​​the second locking through hole 11d; the second locking member 17 is further provided with a second pressing portion 173, and the second pressing portion 173 is connected to the second body 171. When the second locking member 17 is located at the third preset position, the third limiting portion 172 abuts against the opening of the second locking through hole 11d, and when the second locking member 17 is located at the fourth preset position, the third limiting portion 172 is separated from the opening of the second locking through hole 11d. When no external force acts on the first pressing portion 143 or the second pressing portion 173, the second locking member 17 is located at the second preset position, and the second locking through hole 11d does not correspond to the second locking member 17. When an external force acts on the second pressing portion 173, the second locking member 17 moves from the third preset position to the fourth preset position, and the second locking through hole 11d corresponds to the second locking member 17, that is, the second locking member 17 is located above the second locking through hole 11d. When a force is applied along the third direction z, the second locking member 17 is inserted into the second locking through hole 11d. When the external force stops being applied to the second pressing portion 173, the second locking member 17 moves from the fourth preset position to the third preset position, and the limiting step 145 of the second locking member 17 abuts against the hole opening of the second locking through hole 11d.

[0058] In some embodiments, the two ends of the limit member 16 correspond to the first locking member 14 and the second locking member 17 respectively. When the second locking member 17 is located at the third preset position, the other end of the limit member 16 abuts against the second locking member 17, and the second locking member 17 is not allowed to move toward the limit member 16.

[0059] In some embodiments, a fourth limiting portion 174 is extended in the circumferential direction of the second pressing portion 173 . The fourth limiting portion 174 is used to abut against the opening of the second sliding hole 13 c and prevent the locking member from moving away from the limiting member 16 .

[0060] For the reagent bag assembly 20, see Figure 7-Figure 9 The reagent bag assembly 20 includes a bag body 21 and a self-sealing plugging cover 22. The bag body 21 is provided with a receiving chamber 21a and an opening 21b, the opening 21b respectively connects the receiving chamber 21a with the outside, the opening 21b corresponds to the puncture through hole 11a of the connecting plate 11, the self-sealing plugging cover 22 is sealed in the bag body 21, the liquid is loaded into the receiving chamber 21a of the bag body 21, and the liquid extraction mechanism 10 is connected to the receiving chamber 21a after passing through the self-sealing plugging cover 22. When the puncture assembly 12 is connected to the reagent bag assembly 20, the liquid extraction needle 121 of the puncture assembly 12 passes through the self-sealing plugging cover 22 and is connected to the receiving chamber 21a.

[0061] Optionally, the bag body 21 includes a bag body 211, a bag neck 212 and a mounting portion 213. The bag neck 212 is located between the bag body 211 and the mounting portion 213, the bag body 211 is connected to the bag neck 212, one end of the mounting portion 213 is connected to the bag neck 212, the other end of the mounting portion 213 is mounted on the connecting plate 11, the opening 21b is provided at the other end of the mounting portion 213, and the accommodating cavity 21a sequentially extends the bag body 211, the bag neck 212 and the mounting portion 213.

[0062] For the above-mentioned mounting portion 213, the end surface of the bag neck 212 facing the mounting portion 213 is provided with a flexible protrusion 213a, and the flexible protrusion 213a is used to abut against the bottom wall of the slide groove 11c, reducing the risk of the bag body 21 escaping from the slide groove 11c. It can be understood that along the third direction z, the distance between the notch of the slide groove 11c and the bottom wall of the slide groove 11c is smaller than the distance of the mounting portion 213. When the bag body 21 is installed in the slide groove 11c, the flexible protrusion of the mounting portion 213 undergoes elastic deformation, so that the flexible protrusion 213a generates elastic force, and the elastic force of the flexible protrusion 213a always maintains a tendency to reset, so that the flexible protrusion 213a plays an anti-slip role.

[0063] For the self-sealing plug 22, see Fig. 9, along the direction of the opening 21b toward the accommodating chamber 21a, the self-sealing plugging cover 22 is provided with a partial section 22a, the partial section 22a corresponds to the puncture through hole 11a, and along the width direction of the partial section 22a, the two opposite sides of the partial section 22a are pressed against each other, playing a sealing role, reducing the risk of leakage from the self-sealing plugging cover 22. When the puncture assembly 12 is connected to the reagent bag assembly 20, the liquid collection needle 121 of the puncture assembly 12 passes through the partial section 22a and is connected to the accommodating chamber 21a of the bag body 21. The partial section 22a can solve the problem of multiple small holes in the self-sealing plugging cover 22 caused by repeated insertion and extraction of the liquid collection needle 121, resulting in leakage.

[0064] Optionally, in order to reduce the risk of liquid leakage, the reagent bag assembly 20 is also provided with a sealing structure. Specifically, the reagent bag assembly 20 also includes a sealing ring 25; a sealing groove 21d extends from the opening 21b to the accommodating cavity 21a, and the sealing ring 25 is arranged in the sealing groove 21d. When the liquid collection needle 121 of the puncture assembly 12 passes through the local section 22a and is connected to the accommodating cavity 21a of the bag body 21, the inner ring of the sealing ring 25 abuts against the liquid collection needle 121, and the outer ring of the sealing ring 25 abuts against the wall of the sealing groove, thereby achieving sealing.

[0065] In some embodiments, the sealing structure can be replaced by a one-way valve, that is, only allowing liquid to be transported from the bag body 21 to the external object to be contained, but not allowing liquid to enter the bag body 21 from the outside, or only allowing liquid to enter the bag body 21 from the outside, but not allowing liquid to be transported from the bag body 21 to the external object to be contained.

[0066] The reagent bag assembly 20 also includes an outer box 23, such as Figure 2 As shown, the outer box 23 is provided with an inner cavity 23a and a cavity opening 23b, the cavity opening 23b connects the inner cavity 23a with the external object to be filled with liquid, the connecting plate 11 covers the cavity opening 23b, at least one bag body 21 is provided with the inner cavity 23a, and part of the bag body 21 extends from the inner cavity 23a toward the cavity opening 23b.

[0067] In some embodiments, the reagent bag assembly further includes a breathable membrane 24, and at least one bag body 21 is provided with a breathable membrane 24, and the breathable membrane 24 is used to discharge the gas in the bag body 21, such as Figure 7 As shown. Specifically, at least one bag body 21 is provided with a vent hole 21c, and the vent film 24 covers the vent hole 21c. In this embodiment, the number of bag bodies 21 is three, and the mounting portion 213 of the bag body 21 is arranged in the chute 11c. One of the bag bodies 21 is a waste liquid bag, and the waste liquid bag is provided with a vent hole, and the vent film is arranged in the vent hole. When liquid is transported to the waste liquid bag, if accompanied by gas, the gas is discharged through the vent film. It should be noted that the vent film is a kind of gas-permeable but liquid-impermeable film.

[0068] The above-mentioned reagent kit 100 also includes an IC card 30 and a card reader 40. Figure 2 The IC card 30 is arranged on the reagent bag assembly 20, and the card reader 40 is arranged on the liquid taking mechanism 10. The IC card 30 is used to record information, such as detailed parameters of the reagent kit 100 and identification code of the reagent kit 100.
