Description

Technical Field

[0001] This utility model relates to the field of blood collection tube liquid addition technology, specifically to a blood collection tube liquid addition device. Background Technology

[0002] Blood collection tubes are medical devices used to collect, store, and transport blood samples. The red-capped blood collection tubes are additive-free, dry vacuum tubes, primarily used for serum biochemistry, electrolytes, thyroid function, drug testing, HIV testing, tumor markers, and serum immunology tests. Adding liquid to blood collection tubes refers to the process of adding specific liquids to the tubes in medical and laboratory fields. For example, adding a coagulant can accelerate blood clotting, allowing serum or plasma to separate from blood cells more quickly. This is suitable for tests requiring the detection of specific components in serum or plasma, such as biochemical markers.

[0003] Based on the above, the inventors have discovered the following problems: Currently, the liquid addition to blood collection tubes is generally done by medical staff holding a syringe to add liquid into the blood collection tube. This method can only add liquid to a single blood collection tube and is not convenient for adding liquid to multiple blood collection tubes at the same time, which reduces work efficiency and is not suitable for batch processing of blood collection tubes.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings to provide a blood collection tube liquid filling device, in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this invention is to provide a blood collection tube fluid filling device to solve the problems mentioned in the background art.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A blood collection tube filling device includes a driving assembly, a filling assembly, and a placement assembly. The filling assembly is positioned above the driving assembly, and the placement assembly is positioned on the top surface of the driving assembly. The filling assembly is used to simultaneously fill multiple blood collection tubes, and the placement assembly is used to place multiple blood collection tubes to be filled. The filling assembly includes a connecting plate, the bottom end of which is connected to a storage box. The bottom end of the storage box is connected to multiple connecting pipes. Each of the connecting pipes has a solenoid valve installed at the end furthest from the storage box, and the end of the solenoid valve furthest from the connecting pipe is connected to a filling head. The placement assembly includes a base plate, a top plate is provided above the base plate, and multiple blood collection tubes are disposed between the top plate and the base plate.

[0008] Furthermore, the top surface of the base plate is provided with several placement grooves, and the bottom ends of several blood collection tubes are respectively located inside the placement grooves. The top surface of the top plate is provided with several first circular holes, and the bottom end of the top plate is provided with second circular holes directly below the several first circular holes. The diameter of the first circular holes is smaller than the diameter of the second circular holes, and the first and second circular holes are connected. The inner walls of the first and second circular holes are in clearance fit with the outer wall of the blood collection tube near the upper end.

[0009] The beneficial effect of adopting the above-mentioned further solution is that by opening a placement groove on the bottom plate, the bottom end of the blood collection tube can be positioned and supported. The first round hole and the second round hole are opened on the top plate, and the diameter of the first round hole is smaller than that of the second round hole and they are connected. The inner wall is fitted with the outer wall of the blood collection tube near the upper end, which limits the upper end of the blood collection tube, ensures that the blood collection tube is placed vertically, and keeps the blood collection tube stable during the liquid addition process.

[0010] Furthermore, the outer sides of the base plate are connected to first connectors, the top surfaces of the two first connectors are equipped with electric telescopic rods, the movable ends of the two electric telescopic rods are connected to second connectors, and the opposite sides of the two second connectors are respectively fixedly connected to the outer side wall of the top plate.

[0011] The beneficial effect of adopting the above-mentioned further solution is that by setting an electric telescopic rod, the height of the top plate can be easily adjusted. When it is necessary to place or remove the blood collection tube, the top plate can be raised by the electric telescopic rod to expand the space between the top plate and the bottom plate, making it easier for operators to remove the blood collection tube. When adding liquid after placement, the top plate can be lowered by the electric telescopic rod to limit and fix the blood collection tube between the bottom plate and the top plate.

[0012] Furthermore, several liquid infusion heads are located directly above several blood collection tubes, and each of the liquid infusion heads is connected to a liquid flow meter. The number of liquid infusion heads and the number of blood collection tubes are both six.

[0013] The beneficial effect of adopting the above-mentioned further solution is that several liquid dispensing heads are located directly above several blood collection tubes, which can realize the simultaneous dispensing of liquid to multiple blood collection tubes, thereby improving the dispensing efficiency. At the same time, the liquid flow meter connected to the outside of the dispensing head can monitor the dispensing flow rate in real time.

[0014] Furthermore, the storage box is filled with a coagulant, the storage box is transparent, and one end of the connecting plate has an installation hole. A pump is installed inside the installation hole, and the outlet end of the pump extends through the storage box into the interior.

[0015] The beneficial effects of adopting the above-mentioned further solution are that, since the storage box is filled with coagulant, when the solenoid valve at the connecting pipe is opened, the coagulant flows downward under the action of gravity, adding coagulant to the blood collection tube. The storage box is transparent, making it easy for operators to observe the remaining amount of coagulant inside and replenish it in time. By setting up a pump, the outlet end of the pump extends through the storage box into the interior. By connecting the external pipe to the inlet end of the pump, and then connecting the end of the external pipe away from the pump to the container storing the coagulant, it is easy to deliver the coagulant into the interior of the storage box for coagulant replenishment when the pump is working.

[0016] Furthermore, the drive assembly includes a base, a square groove is formed inside one side of the base, a screw is provided inside the square groove, a square plate is threaded to the outside of the screw, the outer wall of the square plate is slidably engaged with the inner wall of the square groove, one end of the square plate extends to the outside of the square groove, and the top surface of one end of the square plate is fixedly connected to the bottom surface of the connecting plate, a micro motor is installed on one side of the top surface of the base, and the output end of the micro motor is fixedly connected to the screw.

[0017] The beneficial effect of adopting the above-mentioned further solution is that, through the coordinated use of the micro motor, screw, square groove and square plate, when the micro servo motor works, it drives the screw to rotate, causing the square plate connected to the external thread of the screw to move up or down under the sliding cooperation with the square groove, thereby realizing the upward or downward movement of the entire liquid filling assembly. After the blood collection tube is limited and fixed between the bottom plate and the top plate, the square plate moves downward, causing the liquid filling assembly to move downward, so that the bottom of the liquid filling head inserts a small part of the blood collection tube for subsequent liquid filling operations. After the liquid filling is completed, the square plate moves upward again, causing the liquid filling assembly to move upward.

[0018] Furthermore, the base plate is disposed on the top surface of the base, and the base has an internal cavity. The bottom end of the cavity is connected to a motor mount by a thread, and a servo motor is mounted on the top surface of the motor mount. The output end of the servo motor passes through the base and is fixedly connected to the bottom end of the base plate.

[0019] The beneficial effect of adopting the above-mentioned further solution is that, by setting a servo motor, after the liquid is added, the servo motor is started, causing the entire placement component to rotate, so as to mix the blood sample and coagulant inside the blood collection tube after the liquid is added.

[0020] Furthermore, the base has a control panel connected to its outer wall opposite the connecting plate, and the control panel is electrically connected to several solenoid valves and several liquid flow meters via wires.

[0021] The beneficial effect of adopting the above-mentioned further solution is that, through the combined use of the control panel, solenoid valve and liquid flow meter, the liquid addition volume can be preset through the control panel, and the liquid flow meter can monitor the liquid addition flow rate in real time during the liquid addition process. When the flow rate reaches the preset value, the operator controls the solenoid valve to close through the control panel to stop the liquid addition.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows: This blood collection tube liquid addition device allows for pre-setting of the liquid addition volume via a control panel. A placement groove on the base plate positions and supports the bottom end of the blood collection tube. A first and second circular hole on the top plate, with the first hole having a smaller diameter than the second hole and being interconnected, with a clearance fit between the inner wall and the outer wall of the blood collection tube near its upper end, limits the upper end of the blood collection tube, ensuring its vertical placement and stability during liquid addition. When liquid addition is needed, a servo motor is activated, driving a screw to rotate. This causes the square plate connected to the screw's external thread to move downwards under the sliding fit with the square groove, thereby moving the entire liquid addition assembly downwards. This allows the liquid addition head to insert a small portion of the blood collection tube. The operator then controls several solenoid valves to open via the control panel. Since the storage box is filled with a coagulant, when the solenoid valve at the connecting pipe... When the valve opens, the coagulant flows downwards under gravity, exits through the dispensing head, and flows into the blood collection tube. This allows for simultaneous dispensing of multiple blood collection tubes, avoiding the need to dispense each tube individually, shortening dispensing time, and improving efficiency. An externally connected flow meter monitors the dispensing flow rate in real time. When the flow rate reaches a preset value, the operator closes the solenoid valve via the control panel to stop dispensing. After dispensing is complete, a servo motor is activated, causing the entire placement assembly to rotate and mix the blood sample and coagulant inside the blood collection tube. The servo motor then drives the screw to rotate, causing the externally threaded square plate to move upwards through its sliding contact with the square groove. This moves the dispensing assembly upwards. Finally, an electric telescopic rod is activated to raise the top plate, expanding the space between the top and bottom plates, facilitating the removal of the blood collection tubes by the operator.

A plurality of first circular holes 35 are provided on the top surface of the top plate 32, and a second circular hole is provided directly below each of the first circular holes 35 at the bottom end of the top plate 32.

When adding liquid after placement, the electric telescopic rod 37 can be used to lower the top plate 32, limiting and fixing the blood collection tube 34 between the bottom plate 31 and the top plate 32.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Please see Figures 1-5The present invention provides the following technical solution: A plurality of liquid inlet heads 26 are respectively located directly above a plurality of blood collection tubes 34. Each liquid inlet head 26 is externally connected to a liquid flow meter 27. The number of liquid inlet heads 26 and the number of blood collection tubes 34 are both six. The storage box 22 is filled with a coagulant accelerator and is transparent. One end of the connecting plate 21 has an internal mounting hole, and a pump 23 is installed inside the mounting hole. The outlet end of the pump 23 extends through the storage box 22 into its interior. The drive assembly 1 includes a base 11. A square groove 14 is formed inside one side of the base 11. A screw 15 is provided inside the square groove 14. A square plate 16 is threadedly connected to the outside of the screw 15. The outer wall of the square plate 16 slides against the inner wall of the square groove 14. One end extends to the outside of the square groove 14, and the top surface of one end of the square plate 16 is fixedly connected to the bottom surface of the connecting plate 21. A micro motor 17 is installed on one side of the top surface of the base 11. The output end of the micro motor 17 is fixedly connected to the screw 15. The base plate 31 is set on the top surface of the base 11. A cavity is opened inside the base 11. The bottom end of the cavity is connected to the motor seat 12 by a thread. A servo motor 13 is installed on the top surface of the motor seat 12. The output end of the servo motor 13 passes through the base 11 and is fixedly connected to the bottom end of the base plate 31. A control panel is connected to the outer wall of the base 11 opposite to the connecting plate 21. The control panel is electrically connected to several solenoid valves 24 and several liquid flow meters 27 by wires. Several liquid filling heads 26 are respectively located at Above several blood collection tubes 34, liquid can be added to multiple blood collection tubes 34 simultaneously, improving the efficiency of liquid addition. Simultaneously, a liquid flow meter 27 connected externally to the liquid inlet 26 can monitor the liquid flow rate in real time. Since the storage box 22 is filled with a coagulant, when the solenoid valve 24 at the connecting pipe 25 is opened, the coagulant flows downwards under gravity, adding coagulant to the blood collection tubes 34. The storage box 22 is transparent, allowing operators to easily observe the remaining amount of coagulant and replenish it promptly. A pump 23 is installed, with its outlet extending through the storage box 22. An external pipe is connected to the inlet of the pump 23, and then the end of the external pipe furthest from the pump 23 is connected to the container storing the coagulant. When the pump... During operation, the accelerator is conveniently delivered to the storage box 22 for replenishment. When the micro servo motor 13 operates, it drives the screw 15 to rotate, causing the square plate 16, which is externally threaded to the screw 15, to move upward or downward under the sliding engagement with the square groove 14. This allows the entire liquid addition assembly 2 to move upward or downward. After the blood collection tube 34 is fixed between the bottom plate 31 and the top plate 32, the square plate 16 moves downward, causing the liquid addition assembly 2 to move downward, allowing the bottom of the liquid addition head 26 to insert a small portion into the blood collection tube 34 for subsequent liquid addition. After liquid addition is completed, the square plate 16 moves upward again, causing the liquid addition assembly 2 to move upward. After liquid addition is completed, the servo motor 13 is activated, causing the entire placement assembly 3 to rotate.After the liquid addition is completed, the blood sample inside blood collection tube 34 is mixed with the coagulant.

[0035] Specifically, the working principle of this blood collection tube liquid addition device is as follows: During use, the liquid addition volume is preset via the control panel. A placement groove 33 is provided on the base plate 31 to position and support the bottom of the blood collection tube 34. A first circular hole 35 and a second circular hole are provided on the top plate 32, with the diameter of the first circular hole 35 being smaller than that of the second circular hole and connected. The inner wall of the first circular hole 35 is fitted with the outer wall of the blood collection tube 34 near its upper end, limiting the upper end of the blood collection tube 34 and ensuring its vertical placement. This keeps the blood collection tube 34 stable during liquid addition. When liquid addition is needed, the servo motor 13 is activated, driving the screw 15 to rotate. This causes the square plate 16, connected to the external thread of the screw 15, to move downwards under the sliding fit with the square groove 14, thereby moving the entire liquid addition assembly 2 downwards. This allows the liquid addition head 26 to insert a small portion of the bottom of the blood collection tube 34. Then, the operator controls several solenoid valves 24 to open via the control panel. Since the storage box 22 is filled with a coagulant, when the solenoid valve 24 at the connecting pipe 25... When opened, the coagulant flows downward under gravity, is discharged through the liquid dispensing head 26 and flows into the blood collection tube 34, allowing for simultaneous liquid dispensing of several blood collection tubes 34, avoiding the need to dispensing liquid one by one, shortening the dispensing time and improving work efficiency. The liquid flow meter 27 connected to the external liquid dispensing head 26 can monitor the liquid flow rate in real time. When the flow rate reaches the preset value, the operator controls the solenoid valve 24 to close via the control panel, stopping the dispensing. After the dispensing is completed, the servo motor 13 is started, causing the entire placement assembly 3 to rotate, mixing the blood sample and coagulant inside the blood collection tube 34 after the dispensing is completed. Then, the servo motor 13 is started, driving the screw 15 to rotate, causing the square plate 16 connected to the external thread of the screw 15 to move upward under the sliding cooperation with the square groove 14, causing the dispensing assembly 2 to move upward. Then, the electric telescopic rod 37 is activated to raise the top plate 32, expanding the space between the top plate 32 and the bottom plate 31, making it easier for the operator to remove the blood collection tube 34.
