Description

Technical Field

[0001] The present application relates to the technical field of reagent storage, and in particular to a reagent storage device. Background Art

[0002] After running for a period of time, impurities will remain in the fluid path of in vitro diagnostic instruments (instruments that obtain certain clinical information by testing human samples). Therefore, strong cleaning reagents are needed to clean the instrument fluid path.

[0003] Since strong cleaning reagents are highly corrosive, when entering the liquid line cleaning process, the sealing plug at the mouth of the reagent bottle needs to be pulled out and the cleaning pipeline needs to be inserted into the reagent bottle; when there is no need to clean the liquid line, the sealing plug needs to be inserted into the mouth of the reagent bottle and the reagent bottle needs to be kept sealed to avoid leakage or deterioration of the cleaning reagent.

[0004] In the existing technology, the insertion and removal of the sealing plug require manual operation, which reduces work efficiency. At the same time, when the cleaning reagent level in the reagent bottle is high and the pressure in the bottle is high, manually pulling out the sealing plug may cause a small amount of cleaning reagent to splash, causing safety hazards.

[0005] Therefore, the existing technology still needs to be improved and developed. Summary of the Invention

[0053] To make the purpose, technical solutions and advantages of this application clearer and more explicit, the following further describes this application in detail with reference to the accompanying drawings and examples. It should be understood that the specific examples described herein are only used to explain this application and are not intended to limit this application.

[0054] The present application provides a reagent storage device, such as Figure 1 、 Figure 3 and Figure 4As shown, the reagent storage device includes: a reagent bottle 1, a sealing plug 2, a supporting mechanism 3, a first driving mechanism 4 and a second driving mechanism 5; the sealing plug 2 cooperates with the bottle mouth of the reagent bottle 1 to seal the reagent bottle 1; the supporting mechanism 3 is slidably connected to the sealing plug 2, specifically, the sealing plug 2 is arranged on the supporting mechanism 3, and can slide in the horizontal direction relative to the supporting mechanism 3, thereby realizing a sliding connection between the supporting mechanism 3 and the sealing plug 2.

[0055] The first driving mechanism 4 is connected to the carrying mechanism 3 and is used to drive the carrying mechanism 3 to move up and down, thereby driving the sealing plug 2 to move up and down through the carrying mechanism 3, so that the sealing plug 2 is inserted downward into the bottle mouth of the reagent bottle 1, or pulled out upward from the bottle mouth of the reagent bottle 1. The second driving mechanism 5 is connected to the carrying mechanism 3 and the sealing plug 2 respectively, and is used to drive the sealing plug 2 to move back and forth in the horizontal direction relative to the carrying mechanism 3, so that the sealing plug 2 approaches and moves away from the carrying mechanism 3 in the horizontal direction, thereby achieving the phase difference and relative position of the sealing plug 2 and the bottle mouth of the reagent bottle 1.

[0056] In this application, the first drive mechanism 4 and the second drive mechanism 5 coordinate with each other, so that the sealing plug 2 can be inserted into the bottle mouth of the reagent bottle 1 and pulled out from the bottle mouth of the reagent bottle 1 without manual operation, avoiding staff contact with the sealing plug 2, thereby improving work efficiency while reducing or even eliminating safety hazards.

[0057] The plugging and unplugging process of the sealing plug 2 is as follows: When the sealing plug 2 closes the bottle mouth of the reagent bottle 1 (i.e. Figure 1 and Figure 3 As shown, the sealing plug 2 is located in the bottle mouth of the reagent bottle 1), and when the instrument needs to be cleaned, the first driving mechanism 4 is started and drives the carrying mechanism 3 to rise, so that the sealing plug 2 moves upward and is pulled out from the bottle mouth of the reagent bottle 1; then the first driving mechanism 4 continues to drive the carrying mechanism 3 to move upward, and during the upward movement of the carrying mechanism 3, the second driving mechanism 5 is started and drives the sealing plug 2 to move in the horizontal direction until the sealing plug 2 is misaligned with the bottle mouth of the reagent bottle 1 (as shown in FIG. Figure 4 As shown), the first driving mechanism 4 stops, and the sealing plug 2 is positioned in a state of being misaligned with the bottle mouth of the reagent bottle 1, so that the bottle mouth of the reagent bottle 1 can be completely exposed, and the cleaning pipeline is inserted into the bottle mouth of the reagent bottle 1 to clean the instrument.

[0058] When cleaning is completed, the first driving mechanism 4 starts in the reverse direction and drives the carrying mechanism 3 to descend; during the descent of the carrying mechanism 3, the second driving mechanism 5 starts in the reverse direction and pushes the sealing plug 2 to move horizontally in a direction away from the carrying mechanism 3, so that the sealing plug 2 is positioned relative to the bottle mouth of the reagent bottle 1; as the carrying mechanism 3 continues to descend, the sealing plug 2 can be inserted into the bottle mouth of the reagent bottle 1, at which time the first driving mechanism 4 stops, and the sealing plug 2 is positioned in a state of matching the bottle mouth of the reagent bottle 1, thereby completing the sealing of the reagent bottle 1.

[0059] In one embodiment of this application, Figure 1 、 Figure 4 and Figure 5 As shown, the reagent storage device further includes a first elastic member 6, one end of which is connected to the first driving mechanism 4, and the other end is connected to the supporting mechanism 3; and when the sealing plug 2 is located in the bottle mouth of the reagent bottle 1, the first elastic member 6 is in a stretched state, so as to generate a downward tensile force on the supporting mechanism 3 through the first elastic member 6. Since the sealing plug 2 is connected to the supporting mechanism 3, when the supporting mechanism 3 is subjected to the downward pulling force of the first elastic member 6, the sealing plug 2 simultaneously generates downward pressure on the bottle mouth of the reagent bottle 1, thereby ensuring the sealing effect of the sealing plug 2 on the bottle mouth of the reagent bottle 1 and reducing the probability of deterioration of the reagent in the reagent bottle 1.

[0060] In one embodiment of the present invention, the first elastic member 6 is arranged vertically, so that the elastic expansion and contraction direction of the first elastic member 6 is the vertical direction. When the first driving mechanism 4 drives the supporting mechanism 3 to move up and down, the first elastic member 6 expands and contracts and deforms in the vertical direction.

[0061] In one implementation of this embodiment, the first elastic member 6 includes a first spring.

[0062] like Figure 1 As shown, the second driving mechanism 5 includes: an adapter 51, a second elastic member 52 and a third elastic member 53; the adapter 51 is arranged on the supporting mechanism 3 and can slide back and forth in the horizontal direction relative to the supporting mechanism 3; the adapter 51 is used to connect the sealing plug 2 with the supporting mechanism 3.

[0063] Specifically, both ends of the adapter 51 extend outside the support mechanism 3 and extend horizontally to both sides of the support mechanism 3. One end of the adapter 51 is connected to the sealing plug 2, and the other end is connected to the third elastic member 53. The second elastic member 52 is arranged horizontally, with its ends respectively connected to the sealing plug 2 and the support mechanism 3. The third elastic member 53 is arranged horizontally, with its end away from the adapter 51 connected to the support mechanism 3.

[0064] When the sealing plug 2 is located within the mouth of the reagent bottle 1, the second elastic member 52 and the third elastic member 53 are both in a stretched state, so that the sealing plug 2 is simultaneously subjected to two opposite forces in the horizontal direction under the tensile force of the second elastic member 52 and the third elastic member 53. The second elastic member 52 exerts a force on the sealing plug 2 in the horizontal direction toward the supporting mechanism 3, while the third elastic member 53 exerts a force on the sealing plug 2 in the horizontal direction away from the supporting mechanism 3.

[0065] In one embodiment of the present application, when the sealing plug 2 is located in the bottle mouth of the reagent bottle 1, the second elastic member 52 and the third elastic member 53 are both in a stretched state, and the third elastic member 53 overcomes the force of the second elastic member 52 so that the sealing plug 2 can seal the bottle mouth of the reagent bottle 1, so that the forces exerted by the second elastic member 52 and the third elastic member 53 on the sealing plug 2 are balanced with each other; then, when the first driving mechanism 4 drives the supporting mechanism 3 to rise to: the sealing plug 2 is pulled out of the bottle mouth of the reagent bottle 1, and the bottle mouth of the reagent bottle 1 does not cause adverse interference to the horizontal movement of the sealing plug 2, the sealing plug 2 will not generate horizontal movement, but will remain in a state where: the sealing plug 2 is separated from the bottle mouth of the reagent bottle 1 and is aligned with the bottle mouth of the reagent bottle 1.

[0066] In this embodiment, Figure 1 As shown, the second driving mechanism 5 also includes a force loading unit 54, which is arranged between the sealing plug 2 and the supporting mechanism 3 and is located on the rising path of the second elastic member 52, so that when the first driving mechanism 4 drives the supporting mechanism 3 to rise until interference occurs between the second elastic member 52 and the force loading unit 54, the second elastic member 52 bends due to the pressure generated by the force loading unit 54, and the force of the second elastic member 52 on the sealing plug 2 increases, thereby adjusting the tensile force of the second elastic member 52 and the third elastic member 53 to an unbalanced state.

[0067] It should be noted that, since the force loading unit 54 is located on the ascending path of the second elastic member 52, when the second elastic member 52 interferes with the force loading unit 54, the interaction force generated between the second elastic member 52 and the force loading unit 54 is in a vertical direction, that is, the force loading unit 54 generates downward pressure on the second elastic member 52, and the second elastic member 52 generates an upward supporting force on the force loading unit 54.

[0068] When interference occurs between the second elastic member 52 and the force loading unit 54, the tensile force of the second elastic member 52 is greater than the tensile force of the third elastic member 53. Under the action of the second elastic member 52, the sealing plug 2 moves horizontally toward the supporting mechanism 3 until the sealing plug 2 is misaligned with the bottle mouth of the reagent bottle 1, the bottle mouth of the reagent bottle 1 is fully opened, and the cleaning pipeline can be inserted into the reagent bottle 1.

[0069] like Figure 2-Figure 5 As shown, the force loading unit 54 includes a column 541, a first guide wheel 542, and a fixed block 543. The column 541 is vertically arranged between the sealing plug 2 and the supporting mechanism 3. The first guide wheel 542 is arranged at the top of the column 541 and is located on the ascending path of the second elastic member 52. The fixed block 543 is provided with two second guide wheels 5431. The fixed block 543 is arranged perpendicular to the column 541, and the two second guide wheels 5431 are symmetrically distributed on both sides of the column 541 along the horizontal direction. The fixed block 543 is connected to the supporting mechanism 3 and can be raised and lowered with the supporting mechanism 3, thereby driving the two second guide wheels 5431 to rise and fall. When the sealing plug 2 is located in the bottle mouth of the reagent bottle 1, the second guide wheel 5431 is lower than the first guide wheel 542, and the second elastic member 52 is horizontal and tangential to the top surface of the second guide wheel 5431.

[0070] It should be noted that the fixing block 543 is used to mount the two second guide wheels 5431. The fixing block 543 can only be raised and lowered with the supporting mechanism 3 and cannot move horizontally. This means that the two second guide wheels 5431 can only be raised and lowered but not moved horizontally. Regardless of whether the two second guide wheels 5431 are raised or lowered, the centers of the two second guide wheels 5431 and the center of the first guide wheel 542 form an isosceles triangle.

[0071] In one implementation of this embodiment, when the second elastic member 52 interferes with the force loading unit 54 and the second elastic member 52 bends under the pressure of the force loading unit 54, the sealing plug 2 moves horizontally toward the supporting mechanism 3 under the action of the second elastic member 52 until the sealing plug 2 is misaligned with the bottle mouth of the reagent bottle 1, the first driving mechanism 4 stops, and the supporting mechanism 3 no longer rises, then the interaction force between the force loading unit 54 and the second elastic member 52 remains unchanged, and the sealing plug 2 is positioned in the current state of being misaligned with the bottle mouth of the reagent bottle 1.

[0072] In one embodiment of this embodiment, the second elastic member 52 comprises a tensioning band, and the third elastic member 53 comprises a second spring. When the tensioning band is stretched horizontally, its surface is flat, which facilitates the first guide wheel 542 and the two second guide wheels 5431 to cooperate with the tensioning band to apply a downward force, thereby ensuring that the sealing plug 2 can smoothly move horizontally toward the supporting mechanism 3 under the loading action of the force loading unit 54.

[0073] The specific process of inserting and removing the sealing plug 2 in this embodiment is as follows: when the sealing plug 2 closes the bottle mouth of the reagent bottle 1 (that is, the sealing plug 2 is located in the bottle mouth of the reagent bottle 1) and the instrument needs to be cleaned, the first driving mechanism 4 is started and drives the supporting mechanism 3 to rise, so that the sealing plug 2 moves upward and is pulled out from the bottle mouth of the reagent bottle 1; the first driving mechanism 4 continues to drive the supporting mechanism 3 to rise, so that the second elastic member 52 and the force loading unit 54 interfere with each other, and the second elastic member 52 changes from a horizontal state to a bent state (such as Figure 4 and Figure 5 As shown); in the process of the supporting mechanism 3 moving upward and the second elastic member 52 generating continuous bending deformation, the sealing plug 2 moves in the horizontal direction under the action of the second elastic member 52 until the sealing plug 2 is located on the side of the column 541 away from the supporting mechanism 3, and the sealing plug 2 is misaligned with the bottle mouth of the reagent bottle 1, the first driving mechanism 4 stops, and the sealing plug 2 is positioned in a state of being misaligned with the bottle mouth of the reagent bottle 1, and the cleaning pipeline can be inserted into the bottle mouth of the reagent bottle 1 to clean the instrument.

[0074] When cleaning is completed, the first driving mechanism 4 starts in the reverse direction and drives the supporting mechanism 3 to descend; as the supporting mechanism 3 descends, the second elastic member 52 disengages from the first guide wheel 542 and gradually returns to a horizontal state; as the supporting mechanism 3 continues to descend, the third elastic member 53 overcomes the force of the second elastic member 52 and drives the sealing plug 2 to move horizontally away from the supporting mechanism 3 until the sealing plug 2 is opposite to the bottle mouth of the reagent bottle 1 and is located directly above the bottle mouth of the reagent bottle 1. During this process, the first driving mechanism 4 is always in the starting state until the sealing plug 2 descends to be inserted into the bottle mouth of the reagent bottle 1, at which time the first driving mechanism 4 stops, completing the sealing of the reagent bottle 1.

[0075] In the present application, when the first drive mechanism 4 and the second drive mechanism 5 coordinate to open and close the sealing plug 2, it is only necessary to supply power to the first drive mechanism 4, and the second drive mechanism 5 can drive the sealing plug 2 to move horizontally by relying solely on mechanical structure coordination, without the need to provide power, thereby saving energy consumption.

[0076] In one embodiment of this application, Figure 1 and Figure 3 As shown, the reagent storage device further includes: a vertical plate 7 and a guide rail 8; the vertical plate 7 is arranged vertically; and the guide rail 8 is vertically disposed on the vertical plate 7. The supporting mechanism 3 is connected to the guide rail 8 and can be raised and lowered along the guide rail 8. The guide rail 8 can guide the raising and lowering of the supporting mechanism 3, ensuring that the raising and lowering movement of the supporting mechanism 3 is a linear motion in the vertical direction.

[0077] It should be noted that the present application does not impose any specific restrictions on the specific structure of the first driving mechanism 4 , as long as the first driving mechanism 4 can satisfy the function of driving the supporting mechanism 3 to move up and down.

[0078] In one embodiment of the present application, the first drive mechanism 4 includes a drive motor 41 and a lead screw 42. The drive shaft of the drive motor 41 is arranged vertically upward, and the lead screw 42 is arranged vertically and connected to the drive shaft of the drive motor 41, so that the lead screw 42 is driven to rotate by the drive motor 41. The lead screw 42 has an external thread, and the support mechanism 3 is threadedly connected to the lead screw 42. When the lead screw 42 rotates, the support mechanism 3 can move up and down according to the principle of lead screw and nut transmission.

[0079] In one embodiment of the present invention, Figure 3As shown, the bearing mechanism 3 includes: a screw guide sleeve 31, a linear bearing 32, a linear bearing fixing sleeve 33, and a bearing plate 34. The bearing plate 34 is fixedly connected to the linear bearing fixing sleeve 33 and is slidably connected to the guide rail 8. The screw guide sleeve 31 is mounted on the screw, the linear bearing 32 is mounted on the screw guide sleeve 31, and the linear bearing fixing sleeve 33 is mounted on the linear bearing 32. When the first driving mechanism 4 is activated, the screw guide sleeve 31, the linear bearing 32, the linear bearing fixing sleeve 33, and the bearing plate 34 can all be raised and lowered.

[0080] In another embodiment of the present application, the first driving mechanism 4 includes a linear motor, a driving shaft of the linear motor is connected to the supporting mechanism 3, and drives the supporting mechanism 3 to rise and fall.

[0081] like Figure 3 and Figure 7 As shown, the reagent storage device also includes: a first sensor 9, a controller 10 and a sensor baffle 11; the first sensor 9 is arranged on the vertical plate 7; the sensor baffle 11 is arranged on the supporting mechanism 3; the controller 10 is respectively connected to the first sensor 9 and the first driving mechanism 4 to obtain the electrical signal transmitted by the first sensor 9 and send a start-stop signal to the first driving mechanism 4.

[0082] When the sealing plug 2 is located in the mouth of the reagent bottle 1, the sensor barrier 11 triggers the first sensor 9. Specifically, the first sensor 9 is used to detect whether the sealing plug 2 has fallen into place; when the controller 10 receives the electrical signal sent by the first sensor 9, it controls the first driving mechanism 4 to stop, and the sealing plug 2 seals the mouth of the reagent bottle 1.

[0083] In one embodiment of this application, Figure 3 and Figure 7 As shown, the reagent storage device also includes a second sensor 12; the second sensor 12 is arranged on the vertical plate 7 and is arranged above the first sensor 9 in the vertical direction; that is, the second sensor 12 and the first sensor 9 are arranged in the vertical direction, and the second sensor 12 is located above the first sensor 9.

[0084] The second sensor 12 is connected to the controller 10. When the sensor barrier 11 triggers the second sensor 12, the force-applying unit 54 interferes with the second elastic member 52 and exerts downward pressure on the second elastic member 52, causing the second elastic member 52 to bend and deform. The second sensor 12 is used to detect whether the sealing plug 2 has risen into position. When the sealing plug 2 has risen into position, the sealing plug 2 is located outside the bottle mouth of the reagent bottle 1 and is offset from the bottle mouth of the reagent bottle 1.

[0085] Specifically, when the second sensor 12 is triggered, the controller 10 controls the first driving mechanism 4 to stop, thereby positioning the sealing plug 2 above the bottle mouth of the reagent bottle 1 and offset from the bottle mouth of the reagent bottle 1 .

[0086] In one embodiment of this application, Figure 1 、 Figure 3 、 Figure 4 and Figure 6 As shown, the reagent storage device further includes: a reagent bottle frame 13 and a guide frame 14; the reagent bottle frame 13 has a reagent bottle accommodating position to accommodate the reagent bottle 1 through the reagent bottle accommodating position; the guide frame 14 has a frame accommodating position to accommodate the reagent bottle frame 13 through the frame accommodating position.

[0087] Specifically, the guide frame 14 is provided with an opening, and the opening is used for inserting and unloading the frame accommodating position of the reagent bottle frame 13. Since the reagent bottle 1 can be sealed when the sealing plug 2 is inserted into the bottle mouth of the reagent bottle 1, that is, the cooperation between the sealing plug 2 and the bottle mouth of the reagent bottle 1 is an interference fit, therefore, the guide frame 14 in this embodiment is fixedly connected to the column 541 and cooperates with the reagent bottle frame 13, so as to limit the reagent bottle 1, and ensure that when the sealing plug 2 is pulled upward, the reagent bottle 1 can remain stationary, and avoid the sealing plug 2 from moving upward and driving the reagent bottle 1 to move.

[0088] like Figure 1 、 Figure 3 、 Figure 4 and Figure 6 As shown, a door handle 15 is provided on the reagent bottle frame 13 corresponding to the opening, and the door handle 15 is used for the user to hold to drag the reagent bottle frame 13 out of the guide frame 14 (as shown in FIG. Figure 6 After that, the reagent bottle 1 in the reagent bottle accommodating position is replaced.

[0089] In one embodiment of this application, Figure 3As shown, the reagent storage device also includes: a first magnetic part 16 and a second magnetic part 17; the first magnetic part 16 is arranged on the outer wall of the reagent bottle frame 13, and the second magnetic part 17 is arranged on the inner wall of the guide frame 14, the positions of the first magnetic part 16 and the second magnetic part 17 correspond to each other, and the first magnetic part 16 and the second magnetic part 17 are magnetically attracted to each other.

[0090] In one implementation of this embodiment, the first magnetic member 16 includes a magnet, and the second magnetic member 17 includes a carbon steel magnet.

[0091] When the reagent bottle frame 13 is pushed into the guide frame 14 until the first magnetic member 16 and the second magnetic member 17 are attracted to each other, the reagent bottle frame 13 is assembled in place in the guide frame 14. The attraction of the first magnetic member 16 and the second magnetic member 17 can further limit the position of the reagent bottle frame 13, thereby improving the stability of the reagent bottle frame 13 in the frame receiving position.

[0092] In one embodiment of this application, Figure 3 and Figure 7 As shown, the reagent storage device further includes a third sensor 18, which is disposed outside the guide frame 14 and connected to the controller 10; the third sensor 18 is used to detect whether the reagent bottle frame 13 is assembled in place in the frame accommodation position.

[0093] Specifically, when the reagent bottle 1 needs to be replaced, the first drive mechanism 4 and the second drive mechanism 5 are adjusted so that the sealing plug 2 is separated from the reagent bottle 1 and misaligned with the bottle mouth of the reagent bottle 1, and then the reagent bottle frame 13 is pulled out from the opening and the reagent bottle 1 is replaced. After the replacement is completed, the reagent bottle frame 13 is pushed into the frame accommodating position until the first magnetic member 16 and the second magnetic member 17 are attracted, and the reagent bottle frame 13 triggers the third sensor 18, and the third sensor 18 sends an electrical signal to the controller 10. After the controller 10 receives the electrical signal sent by the third sensor 18, it can perform subsequent control operations on the first drive mechanism 4.

[0094] In one embodiment of this application, Figure 3 and Figure 7As shown, the reagent storage device further includes a fourth sensor 19, which is disposed within the guide frame 14 and is configured to detect whether the reagent bottle 1 is placed within the reagent bottle frame 13. The fourth sensor 19 is connected to the controller 10; when the reagent bottle 1 is placed within the reagent bottle frame 13, the reagent bottle 1 triggers the fourth sensor 19, which then sends an electrical signal to the controller 10.

[0095] It is understandable that only when the controller 10 receives both the electrical signal sent by the third sensor 18 and the electrical signal sent by the fourth sensor 19, can the controller 10 control the first driving mechanism 4 to operate and perform subsequent sealing plug 2 insertion and removal operations.

[0096] In summary, the present application provides a kind of reagent storage device, which includes a reagent bottle; a sealing plug, which cooperates with the bottle mouth of the reagent bottle; a carrying mechanism, which is slidably connected to the sealing plug; a first driving mechanism, which is connected to the carrying mechanism and is used to drive the carrying mechanism to lift and lower, so as to drive the sealing plug to be pulled out and inserted from the bottle mouth of the reagent bottle; a second driving mechanism, which is respectively connected to the carrying mechanism and the sealing plug, and is used to drive the sealing plug to approach and move away from the carrying mechanism in the horizontal direction, so that the sealing plug is misaligned and aligned with the bottle mouth of the reagent bottle. In the present application, through the mutual coordination of the first driving mechanism and the second driving mechanism, the sealing plug can be inserted into the bottle mouth of the reagent bottle under non-manual operation, and pulled out from the bottle mouth of the reagent bottle, thereby avoiding the staff from contacting the sealing plug, thereby reducing or even eliminating safety hazards while improving work efficiency.

[0097] It should be understood that the application of this application is not limited to the above examples. For ordinary technicians in this field, they can make improvements or changes based on the above description. All these improvements and changes should fall within the scope of protection of the claims attached to this application.
