All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-10 As shown, the present invention is a dynamic automatic liquid metering and adding device, including: a weighing operation platform 1, a weighing tray 2 installed on the top of the weighing operation platform 1, a support back plate part 3 fixedly arranged on the rear end face of the weighing operation platform 1, a support plate part 12 arranged above the weighing tray 2, and an infusion head 13 fixedly arranged on the surface of the support plate part 12; a display part and operation buttons are arranged on the inclined surface at the front end of the weighing operation platform 1 for operating the infusion head 13 to dispense a specified amount of fixing liquid. A weighing device is also arranged on the top of the weighing operation platform 1. After placing the weighing tray 2 on the weighing device and placing a sample on the weighing tray 2, the weight is automatically displayed on the display part. Different organs have different liquid adding multiples. The data of different liquid adding multiples are written into the database. The corresponding organ data is selected by the knob on the weighing operation platform 1. After the operation start button is activated, the infusion head 13 connected to the actuator will dispense a specified amount of fixing liquid into the sample bag or bottle. The principle is that after selecting the corresponding organ data, the weighing device realizes precise delivery of the fixing liquid through weighing feedback and dynamic control according to the liquid adding multiple in the database, and is matched with the actuator. The liquid adding multiple can also be customized and a specified amount can be delivered to the sample bag or bottle.

[0024] A bottle mouth slot 4 is opened at the top of the weighing tray 2. A positioning card hole 5 is opened at the bottom of the bottle mouth slot 4. A positioning insertion rod part 6 is longitudinally inserted into the slot of the positioning card hole 5. The bottle mouth slot 4 is in the shape of a circular groove, and a large number of positioning card holes 5 are evenly distributed at the bottom of the bottle mouth slot 4. The positioning insertion rod part 6 can be inserted into each group of positioning card holes 5. After inserting the positioning insertion rod part 6 into the positioning card hole 5, multiple groups of positioning insertion rod parts 6 are distributed in a rectangular shape. The bottom of the bottle containing the specimen can be placed at the bottom of the bottle mouth slot 4, and the bottle body is restricted inside the positioning insertion rod part 6, thereby maintaining the stability of the bottle body. During the process of the infusion head 13 dispensing the fixing liquid, medical staff can let go and perform other tasks, reducing the occupation time of medical staff and maintaining the stability of the bottle body.

[0025] On the top of the weighing tray 2, there are oppositely distributed cover plates 39 fixedly installed. Inside the cover plates 39, there are air hole parts 40 opened. At the bottom of the surface cavity of the cover plates 39, there is an exhaust fan 43 installed. Inside the cover plates 39 near the bottom, there is a drawer cabinet 41 installed. On the surface of the drawer cabinet 41, there are cabinet openings 42 opened. The upper halves of the two groups of cover plates 39 arc-extend above the bottle mouth slot 4. And after the exhaust fan 43 inside the cover plates 39 is started, the air flow can enter into the cover plates 39 along the air hole parts 40 and enter into the drawer cabinet 41 from the exhaust fan 43. Formaldehyde adsorption materials are placed in the drawer cabinet 41, which can reduce the leakage of formaldehyde to a certain extent. And the drawer cabinet 41 can be pulled out from inside the cover plates 39, and can be lifted to replace the formaldehyde adsorption materials inside the drawer cabinet 41. And the cover plates 39 are arranged in two groups on both sides of the infusion head 13, which has a good adsorption effect on the leaked formaldehyde. The drawer cabinet 41 is below the exhaust fan 43. The exhaust fan 43 attracts the air flow to enter into the drawer cabinet 41 from the cover plates 39, and the air flow is discharged from the cabinet openings 42. The drawer cabinet 41 is a drawer-type cabinet, and formaldehyde adsorption materials are placed inside the cabinet.

[0026] On the surface of the support back plate part 3, there is a back support plate 8 fixedly installed. On the top of the back support plate 8, there are two groups of spaced limit baffles 9 fixedly installed. Inside the arc-shaped inner sides of the limit baffles 9, there is a fixed liquid storage container 17 assembled. When it is necessary to use a larger large-barrel storage container, directly connect a large-volume container, and the device can be directly placed on the desktop on one side. On the top of the back support plate 8, there are bayonets for the fixed liquid storage container 17 to be inserted, so that the two groups of fixed liquid storage containers 17 are stably placed on the top of the back support plate 8. And the top of the fixed liquid storage container 17 is open, and there is a bottle body cover plate 18 for the top opening of the fixed liquid storage container 17. The bottle body cover plate 18 can be screwed into the opening of the fixed liquid storage container 17. In the central opening of the back support plate 8, there is a rubber sealing ring 21 installed. Inside the rubber sealing ring 21, there is a conduit part 20 passed through. The other end of the conduit part 20 is connected to the liquid adding pump body 10 and the infusion head 13. On the bottom wall of the bottle body cover plate 18, there is a liquid level sensor 19 extending into the cavity of the fixed liquid storage container 17. A sufficient amount of fixed liquid is stored in the fixed liquid storage container 17, and the liquid level sensor 19 can monitor the remaining content of the fixed liquid in the fixed liquid storage container 17 and display it on the display part in front of the weighing operation platform 1. And the existence of the rubber sealing ring 21 can improve the relative sealing effect when the conduit part 20 passes through the center of the bottle body cover plate 18, thereby greatly reducing the leakage of the fixed liquid stored in the fixed liquid storage container 17. And the conduit part 20 is connected to the infusion head 13 after passing through the liquid adding pump body 10. Through the drive of the liquid adding pump body 10, the fixed liquid at the end of the conduit part 20 is discharged downward from the infusion head 13 along the conduit part 20 and the liquid adding pump body 10. And the bottle body is placed directly below the infusion head 13, so the automatic addition of the fixed liquid can be realized.

[0027] The surface of the support back plate part 3 is provided with displacement adjustment holes 7. A connecting support plate 14 that passes through the displacement adjustment holes 7 and extends to the other side of the support back plate part 3 is fixedly arranged on the side surface of the support plate part 12. Among them, two groups of displacement adjustment holes 7 are provided, so that the connecting support plate 14 passes through the two groups of displacement adjustment holes 7 and can longitudinally move along the slots of the displacement adjustment holes 7. An electric push rod two 16 is fixedly arranged on the surface of the support back plate part 3. The output end of the electric push rod two 16 is connected with a pushing sticker 15. The pushing sticker 15 is in sliding fit with the connecting support plate 14. Driven by the electric push rod two 16, the pushing sticker 15 can push the connecting support plate 14 to move, so that the support plate part 12 fixedly connected with the connecting support plate 14 can drag the infusion head 13 to move back and forth above the bottle mouth slot 4. At the same time, a stop block extending forward is also fixedly arranged on the surface of the support back plate part 3. An electric push rod one 11 is fixedly arranged on the bottom wall of the stop block, so that the output end of the electric push rod one 11 faces vertically downward. Among them, a chute is opened at the top of the support plate part 12, so that the output end of the electric push rod one 11 is embedded in the chute. The shape of the chute is side U-shaped, so that the support plate part 12 can be connected with the output end of the electric push rod one 11 and can slide relatively. Driven by the electric push rod one 11, the whole support plate part 12 can also be pushed to longitudinally move above the bottle mouth slot 4, thereby adjusting the use height of the infusion head 13 and facilitating the infusion head 13 to perform the fixed liquid conveying action.

[0028] The third electric push rod 22 is fixedly arranged on the side wall of the support plate part 12. The output end of the third electric push rod 22 is connected with a push connecting rod 23. The front end of the push connecting rod 23 is rotatably connected with an adjusting support rod 24. The other end of the adjusting support rod 24 is rotatably connected with a detachable dial rod 25. And the detachable dial rod 25 can be detached from the adjusting support rod 24 and the cross support plate 26. The front end of the support plate part 12 is fixedly provided with the detachable dial rod 25. The detachable dial rod 25 is rotatably connected with the cross support plate 26. Wherein, a dial plate 27 is fixedly arranged at the bottom end of the cross support plate 26. And the dial plate 27 is placed directly below the infusion head 13. The support column part 28 is installed on the top of the weighing support plate 2. The top of the support column part 28 is fixedly provided with a support cross vertical plate 29. Cross plate rotating shafts 30 are arranged at both ends of the support cross vertical plate 29. A clamping block 31 is connected to the bottom of the cross plate rotating shaft 30. A back plate 32 fixedly arranged on the surface of the clamping block 31 is arranged below the support cross vertical plate 29. A spring part 33 is connected between the two groups of back plates 32; Two groups of clamping blocks 31 are arranged on one side of the support cross vertical plate 29. And there is a gap between the two groups of clamping blocks 31. The front ends of the two groups of clamping blocks 31 are provided with inclined surfaces. The two groups of inclined surfaces are combined into a V shape. The two groups of support column parts 28 are respectively located on both sides below the infusion head 13. One group of support column parts 28 is connected with two groups of clamping blocks 31. And the clamping blocks 31 are respectively rotatably connected with the support cross vertical plate 29 through the cross plate rotating shafts 30. The gap between the two groups of clamping blocks 31 is used to clamp the edge of the sample bag. During actual use, the two ends of the sample bag are inserted into the gap of the clamping block 31. Then through the elastic action of the spring part 33, the two groups of clamping blocks 31 can clamp the edge of the sample bag placed at the gap of the clamping block 31. And the bottom area of the sample bag can be directly placed on the upper end surface of the weighing support plate 2. Due to the existence of the V-shaped inclined surface, it is more convenient for medical staff to take and place the sample bag. During actual use, the two ends of the sample bag are clamped between the clamping blocks 31. After the bottom of the sample bag is placed above the weighing support plate 2, just let go. As the first electric push rod 11 drives the support plate part 12 to move downward, the infusion head 13 moves downward accordingly. At the same time, the dial plate 27 at the bottom of the infusion head 13 moves downward. The dial plate 27 can first extend into the sample bag. Subsequently, through the drive of the third electric push rod 22, the entire detachable dial rod 25 rotates. The rotation of the detachable dial rod 25 can drive the dial plate 27 to rotate. After the dial plate 27 rotates, it can push the bag mouth to one side to open, and then the fixing liquid can be poured into the sample bag in the clamped state below through the infusion head 13.

[0029] A sliding cross groove 34 is opened at the top of the weighing support plate 2. A servo motor 38 is arranged inside the weighing support plate 2. The output end of the servo motor 38 is connected with a positive and reverse thread lead screw 36. A moving sleeve part 37 is externally meshed and sleeved on the positive and reverse thread lead screw 36. The top of the moving sleeve part 37 extends upward through the sliding cross groove 34 and is connected with a moving slider 35 that slides along the groove of the sliding cross groove 34. During actual use, the driving of the servo motor 38 can synchronously drive the two sets of moving sleeve parts 37 to move the moving slider 35. The moving slider 35 can slide within the sliding groove of the sliding cross groove 34, thereby displacing the servo motor 38 fixedly connected to the top of the moving slider 35, so as to adjust the distance between the two sets of support column parts 28. During the process of the dial plate 27 stretching open the bag mouth, the two sets of moving sliders 35 drive the two sets of support column parts 28 to approach each other, stretching open the bag mouth as large as possible to prevent the infusion head 13 from exposing the fixing liquid. After the infusion head 13 has dispensed an appropriate amount of fixing liquid, the electric push rod 1 drives the support plate part 12 to return to the initial position, and at the same time the two sets of support column parts 28 are pulled apart, thus automatically closing the opening of the sample bag.

[0030] Working principle: Place the bottom of the bottle containing the specimen on the bottom of the slot 4 of the bottle mouth, and confine the bottle body inside the positioning plug rod part 6, thereby maintaining the stability of the bottle body. During the process of the infusion head 13 injecting the fixing liquid, medical staff can release their hands to perform other operations. Subsequently, they can operate the buttons on the surface of the weighing operation platform 1, select through the touch screen or buttons or rotate the buttons to adjust to the currently corresponding organ selection. Then, start the liquid adding pump body 10. The front end of the conduit part 20 connected to the liquid adding pump body 10 extends into the fixing liquid storage container 17. The fixing liquid storage container 17 stores a sufficient amount of fixing liquid. The fixing liquid enters the infusion head 13 along the conduit part 20 and the liquid adding pump body 10. The infusion head 13 and the bottle body are in the same vertical direction. Driven by the electric push rod 11, the support plate part 12 moves downward, so that the infusion head 13 gets closer to the bottle mouth. The fixing liquid is discharged downward from the infusion head 13. According to the weighed weight, an appropriate amount of fixing liquid is conveyed from the infusion head 13 into the bottle body. After injecting a sufficient amount of fixing liquid, the bottle body can be pulled out upward from the slot of the bottle mouth slot 4. During the liquid discharging process, the exhaust fan 43 inside the cover plate 39 is started simultaneously. The adsorption air flow can enter the cover plate 39 along the air hole part 40 and enter the pull-out cabinet 41 from the exhaust fan 43. The pull-out cabinet 41 contains formaldehyde adsorption materials, which can reduce formaldehyde leakage to a certain extent. The pull-out cabinet 41 can be pulled out from the cover plate 39 and can be lifted to replace the formaldehyde adsorption materials inside the pull-out cabinet 41. When it is necessary to fill the sample bag with the fixing liquid, the side rod of the detachable lever 25 can be clamped into the cross frame plate 26, making the side rod movable with the cross frame plate 26. At the same time, the top of the detachable lever 25 is connected to the adjusting support rod 24 and keeps the detachable lever 25 movably connected to the adjusting support rod 24. The two ends of the sample bag are stuffed into the gap of the clamping block 31. Then, through the elastic action of the spring part 33, the two groups of clamping blocks 31 can clamp the edge of the sample bag placed in the gap of the clamping block 31. The bottom area of the sample bag directly sits on the upper end surface of the weighing support plate 2. Due to the existence of the V-shaped inclined surface part, it is more convenient for medical staff to take and place the sample bag. During the actual use process, clamp the two ends of the sample bag between the clamping blocks 31, and let go after the bottom of the sample bag sits above the weighing support plate 2. Driven by the electric push rod 11, the support plate part 12 moves downward, so that the infusion head 13 moves downward. At the same time, the paddle plate 27 at the bottom of the infusion head 13 moves downward. The paddle plate 27 can first extend into the sample bag. Then, driven by the electric push rod 3 22, the entire detachable lever 25 rotates. The rotation of the detachable lever 25 drives the paddle plate 27 to rotate. After the paddle plate 27 rotates, it can push the bag mouth to one side, thereby opening the entire bag mouth. Then, the fixing liquid can be injected into the sample bag in the clamped state below through the infusion head 13.
