[0024] 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.

[0025] Please see Figure 1-5 The present invention provides the following technical solution:

[0026] A device for precise quantitative filling of blood collection tube additives includes a workbench 1, three mounting brackets 2 are bolted to the rear side of the top of the workbench 1, and storage tanks 3 for holding different additives are respectively bolted to the rear side of the top of the three mounting brackets 2. A height adjustment cylinder 4 is provided on the front side inside the mounting bracket 2, and a quantitative filling component 5 is bolted to the bottom of the height adjustment cylinder 4. A horizontal block 6 is bolted to the top of the workbench 1, and a first sliding groove 7 is opened inside the horizontal block 6. A slider 8 is slidably arranged inside the first sliding groove 7, and an adaptive clamping metering component 9 is bolted to the top of the slider 8.

[0027] The quantitative filling component 5 includes a mounting frame 51, the top of which is bolted to the bottom of the height adjustment electric cylinder 4. A quantitative propulsion electric cylinder 52 and a temporary storage tank 53 are bolted to the inside of the mounting frame 51. A piston 54 is slidably arranged inside the temporary storage tank 53. The top of the piston 54 is bolted to the bottom of the quantitative propulsion electric cylinder 52. An injection pipe 55 is fixedly connected to the bottom of the temporary storage tank 53.

[0028] In this embodiment: the workbench 1 serves as the supporting foundation for the entire device, firmly placed in the working area. Three mounting brackets 2, bolted to the top rear of the workbench 1, each serve as a support and fixing component. Three liquid storage tanks 3 on the top rear of the mounting brackets 2 respectively hold different additives, storing raw materials for subsequent filling. The height adjustment cylinder 4 on the front inside the mounting bracket 2 is at its initial height, and the quantitative filling component 5 bolted to its bottom is also in its corresponding initial position. A first sliding groove 7 is opened inside the horizontal block 6 bolted to the top of the workbench 1. The slider 8 within the first sliding groove 7 is in its initial sliding position, and the adaptive clamping metering component 9 bolted to the top of the slider 8 is also ready. At this time, the operator places the blood collection tube to be filled with additive onto the adaptive clamping metering component 9, ready to begin adding the additive. In the quantitative filling of the additive, the mounting frame 51 in the quantitative filling component 5 moves with the height adjustment electric cylinder 4, and the quantitative propulsion electric cylinder 52 and the temporary storage tank 53 connected inside it also move accordingly. The quantitative propulsion electric cylinder 52 controls the piston 54 to move upward, and the additive in the storage tank 3 automatically flows into the temporary storage tank 53. When the additive in the temporary storage tank 53 reaches the predetermined amount, the liquid addition stops. At this time, the height adjustment electric cylinder 4 continues to operate, so that the injection tube 55 is close to the blood collection tube placed on the adaptive clamping metering component 9. Then, the quantitative propulsion electric cylinder 52 pushes the piston 54 to move downward, and the additive in the temporary storage tank 53 is accurately injected into the blood collection tube through the injection tube 55, realizing the precise quantitative filling of the additive. The adaptive clamping metering component 9 can adapt to blood collection tubes of different specifications to a certain extent.

[0029] Specifically, such as Figure 2 As shown, the adaptive clamping metering assembly 9 includes a first mounting plate 91, the bottom of which is bolted to the top of the slider 8.

[0030] Specifically, such as Figure 2 As shown, four high-sensitivity pressure sensors 92 are bolted to the top of the first mounting plate 91, and a second mounting plate 93 is bolted between the tops of the four high-sensitivity pressure sensors 92.

[0031] Specifically, such as Figure 2As shown, a clamping barrel 94 is bolted to the top of the second mounting plate 93. Several second sliding grooves 95 are provided inside the clamping barrel 94. A square rod 96 is slidably arranged inside the second sliding groove 95. A spring 97 is provided inside the second sliding groove 95. The two ends of the spring 97 are respectively connected to the square rod 96 and the inner wall of the clamping barrel 94. A clamping strip 98 is bolted to the side of the square rod 96 away from the spring 97. The clamping strip 98 is located inside the clamping barrel 94.

[0032] In this embodiment: the bottom of the first mounting plate 91 is bolted to the top of the slider 8, providing support for the entire adaptive clamping and metering assembly 9. The four high-sensitivity pressure sensors 92 on the top of the first mounting plate 91 sense the pressure changes generated when the blood collection tube is placed in real time. After the blood collection tube is placed into the clamping barrel 94, it will squeeze the clamping strip 98 inside. The clamping strip 98 is connected to the square rod 96. The square rod 96 slides in the second sliding groove 95 opened inside the clamping barrel 94, and at the same time compresses the spring 97 in the second sliding groove 95. The elastic force generated by the spring 97 makes the clamping strip 98 tightly clamp the blood collection tube, realizing adaptive clamping and fixing of blood collection tubes of different specifications. As the additive is filled, the high-sensitivity pressure sensor 92 continuously monitors the change in the weight of the blood collection tube and transmits the pressure signal to the control system. When the preset filling amount is reached, the control system realizes precise control of the amount of additive injected from multiple aspects through the opening and closing of the first electric ball valve 10 and the quantitative propulsion of the quantitative propulsion cylinder 52.

[0033] Specifically, such as Figure 5 , Figure 1 As shown, the injection tube 55 is equipped with a first electrically controlled ball valve 10, and a controller 11 is bolted to the left side of the rear side of the top of the workbench 1.

[0034] Specifically, such as Figure 5 As shown, a connecting pipe 12 is fixedly connected to the rear side of the temporary storage tank 53, and a liquid addition hose 13 is fixedly connected between the rear side of the connecting pipe 12 and the bottom of the storage tank 3. A second electrically controlled ball valve 14 is installed inside the connecting pipe 12.

[0035] In this embodiment: During the quantitative filling process of the additive, the quantitative filling component 5 operates according to a predetermined program. When it is necessary to add additive to the temporary storage tank 53, the second electrically controlled ball valve 14 opens and the first electrically controlled ball valve 10 closes. The additive in the storage tank 3 flows into the temporary storage tank 53 through the liquid addition hose 13 and the connecting pipe 12. At this time, the quantitative propulsion cylinder 52 controls the piston 54 to move upward, which can draw the additive from the storage tank 3. When the additive in the temporary storage tank 53 reaches the predetermined amount, the second electrically controlled ball valve 14 closes, stopping the liquid addition. When it is necessary to inject into the blood collection tube... When the additive is added, the height adjustment electric cylinder 4 drives the mounting frame 51 and the quantitative filling component 5 to descend, bringing the injection tube 55 closer to the blood collection tube. Then, the first electrically controlled ball valve 10 opens, and the quantitative propulsion electric cylinder 52 pushes the piston 54 downward, accurately injecting the additive in the temporary storage tank 53 into the blood collection tube through the injection tube 55. Since this quantitative filling method is minimally affected by the viscosity of the additive, it can ensure that the additive is accurately filled into the blood collection tube, improving the accuracy of the blood collection tube detection results. Combined with the high-sensitivity pressure sensor 92, the injection accuracy can be further improved.

[0036] Specifically, such as Figure 5 As shown, two guide rods 15 are slidably arranged on the front side inside the mounting bracket 2, and the bottom of the two guide rods 15 are respectively bolted to the two sides of the top of the mounting frame 51.

[0037] Specifically, such as Figure 3 As shown, the internal thread of the slider 8 is connected to a threaded rod 16. The threaded rod 16 is rotatably connected to the horizontal block 6 on the side near the inner wall of the horizontal block 6. A motor 17 is bolted to the right side of the horizontal block 6. The output shaft of the motor 17 extends into the interior of the horizontal block 6 and is bolted to the threaded rod 16.

[0038] In this embodiment: when the height adjustment cylinder 4 drives the mounting frame 51 to move up and down, the bottom of the two guide rods 15 are bolted to the top sides of the mounting frame 51 to ensure that the mounting frame 51 maintains a stable and accurate orientation during movement, avoiding shaking or deviation, and ensuring that the quantitative filling component 5 can accurately reach the designated position to fill the additive. At the same time, the movement of the slider 8 in the first sliding groove 7 inside the horizontal block 6 is also controlled by the corresponding drive component. After the motor 17 bolted to the right side of the horizontal block 6 is started, its output shaft drives the threaded rod 16 bolted to it to rotate. Since the internal thread of the slider 8 is connected to the threaded rod 16, the rotation of the threaded rod 16 will cause the slider 8 to slide in a specific direction in the first sliding groove 7, thereby driving the adaptive clamping metering component 9 to move to the appropriate position so as to cooperate with the quantitative filling component 5 to complete the additive filling work of the blood collection tube.

[0039] Working principle: The workbench 1 is stably placed in the work area as a supporting base. Three mounting brackets 2 on the rear of its top support and fix the liquid storage tanks 3 containing different additives on the rear of its top. The height adjustment electric cylinder 4 on the front of the mounting bracket 2 is initially at a certain height, and the quantitative filling component 5 bolted to its bottom is also in the corresponding initial position. The slider 8 in the first sliding groove 7 in the horizontal block 6 at the top of the workbench 1 is in the initial sliding position, and the adaptive clamping metering component 9 bolted to the top is ready. The operator places the blood collection tube to be filled into the adaptive clamping metering component. On component 9, after the blood collection tube is placed into the clamping bucket 94, the internal clamping strip 98 is squeezed, causing the connected square rod 96 to slide in the second sliding groove 95 and compress the spring 97. The elastic force of the spring 97 causes the clamping strip 98 to clamp the blood collection tube, achieving self-adaptive clamping and fixation. At this time, the quantitative propulsion electric cylinder 52 controls the piston 54 to move upward, the second electric ball valve 14 opens, and the first electric ball valve 10 closes. The additive in the storage tank 3 flows into the temporary storage bucket 53 through the liquid addition hose 13 and the connecting pipe 12. After the predetermined liquid addition amount is reached, the second electric ball valve 14 closes. Then, the high The electric cylinder 4 lowers the mounting frame 51 and the quantitative filling component 5, bringing the injection tube 55 closer to the blood collection tube. The first electrically controlled ball valve 10 opens, and the quantitative propulsion cylinder 52 pushes the piston 54 downward, precisely injecting the additive from the temporary storage tank 53 into the blood collection tube. During the filling process, the four high-sensitivity pressure sensors 92 on the top of the first mounting plate 91 sense the pressure changes in the blood collection tube in real time, continuously monitor the weight changes, and transmit the signals to the control system. When the preset filling amount is reached, the control system achieves precise control by controlling the opening and closing of the first electrically controlled ball valve 10 and the quantitative propulsion cylinder 52 to advance the tube quantitatively. At the same time, the two guide rods 15 ensure that the mounting frame 51 moves stably and accurately. After the motor 17 on the right side of the horizontal block 6 starts, its output shaft drives the threaded rod 16 to rotate, causing the slider 8 to slide in the first sliding groove 7, which moves the adaptive clamping metering component 9 to the appropriate position to cooperate with the quantitative filling component 5 to complete the filling work. This quantitative filling method is minimally affected by the viscosity of the additive. Combined with the high-sensitivity pressure sensor 92, it can ensure accurate filling of the additive, improve the accuracy of blood collection tube detection results, and increase the injection precision.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
