Description

Technical Field

[0001] This utility model belongs to the field of medical testing technology, specifically relating to a liquid addition and dilution device. Background Technology

[0002] When performing blood cell analysis, whole blood needs to be appropriately diluted to ensure that blood cells are evenly dispersed in the counter and to facilitate accurate counting of various blood cell types. Similarly, when detecting certain high-concentration substances in serum, serum samples also need to be diluted to ensure accuracy and keep the results within the instrument's linear range. Traditional devices have limited sample management capabilities, and when diluting multiple samples, sample confusion can easily occur, affecting the accuracy and efficiency of the test. Furthermore, adding diluent to blood samples in different test tubes requires matching the tube openings, which can lead to confusion and makes it difficult to match batches of test tubes. This also results in low efficiency in injecting diluent into blood samples. Utility Model Content

[0003] This invention provides a liquid dilution device that solves the problem that existing liquid dilution devices are prone to confusion when adding liquid to a large number of samples, and are not convenient for quickly and sequentially injecting diluent into each test tube.

[0004] This utility model provides the following technical solution: It includes a base frame, on which a support ring is provided. An adjusting plate is rotatably connected to the inner wall of the support ring. Several through holes are provided on the adjusting plate. A connecting rod is fixedly connected to the bottom end of the adjusting plate. Several support blocks matching the through holes are provided on the outer side of the connecting rod. A sealing ring is provided above the adjusting plate. A first and second symmetrical clearance holes are provided on the sealing ring. An installation rod is installed on one side of the base frame. A liquid adding component is installed on the installation rod. An installation groove is provided on the installation rod. A sliding rod is slidably connected to the inner wall of the installation groove. A spring is sleeved on the outer wall of the sliding rod. An arc-shaped clamping plate is fixedly connected to one end of the sliding rod.

[0005] The base frame and the support ring are connected by a fixing rod. Several locking rods are fixedly connected to the top of the support ring, and an installation plate that engages with the locking rods is fixedly connected to the outer wall of the sealing ring.

[0006] The base frame has a support plate fixedly connected to its inner wall, and a rotating shaft is fixedly connected to the top of the support plate. The rotating shaft is rotatably connected to the bottom of the connecting rod.

[0007] The support block and the connecting rod are connected by a support frame, and a rotating rod is installed at the center of the adjusting plate.

[0008] The bottom end of the arc-shaped plate is fixedly connected to an "L"-shaped rod, which is slidably connected to the mounting rod, and one end of the spring is fixedly connected to the inner wall of the mounting groove.

[0009] The beneficial effects of this utility model are as follows: through the cooperation of components such as the arc-shaped clamping plate and spring, when adjusting the position of the test tube by rotating the adjusting plate, connecting rod and support block, it is ensured that the support block always corresponds to the injection end at the center of the bottom of the liquid addition component, which effectively avoids liquid addition deviation. The design of adding liquid through the first clearance hole and sealing and removing the test tube through the second clearance hole allows the device to perform dilution operations on the test tubes in sequence, avoiding confusion between samples.

[0010] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0016] Please see Figures 1-4The present invention provides the following technical solution: a base frame 1, a support ring 11 on the base frame 1, an adjusting plate 2 rotatably connected to the inner wall of the support ring 11, a plurality of through holes 21 on the adjusting plate 2, a connecting rod 22 fixedly connected to the bottom end of the adjusting plate 2, a plurality of support blocks 24 matching the through holes 21 on the outer side of the connecting rod 22, a sealing ring 3 on the top of the adjusting plate 2, a first clearance hole 31 and a second clearance hole 32 symmetrically opened on the sealing ring 3, an installation rod 4 installed on one side of the base frame 1, a liquid adding component 41 installed on the installation rod 4, an installation groove 42 opened on the installation rod 4, a sliding rod 43 slidably connected to the inner wall of the installation groove 42, a spring 45 sleeved on the outer wall of the sliding rod 43, and an arc-shaped clamping plate 44 fixedly connected to one end of the sliding rod 43.

[0017] In this implementation scheme: the base frame 1 serves as the carrier of the supporting device. A support ring 11 positioned above the base frame 1 limits the top outer wall of the test tube. During use, the test tube is installed through several equidistantly distributed perforations 21 on the adjusting plate 2. The test tube passes through the perforations 21, allowing its bottom to rest on a support block 24 positioned below the adjusting plate 2. The test tube is stably supported on the support block 24, with its top limited by the adjusting plate 2. The support block 24 and the adjusting plate 2 are connected by a connecting rod 22 and a support frame 23, enabling the device to... The position of the test tube is adjusted by rotating the adjusting plate 2. When diluting the blood in the test tube using the device, the sealing ring 3 can be installed above the adjusting plate 2, so that the bottom of the sealing ring 3 can fit tightly against the end face of the test tube, protecting the blood to be diluted in the test tube. When dilution is required, the mounting rod 4 installed on the outside of the base frame 1 can be installed on the liquid addition component 41, so that the liquid addition component 41 is supported above the adjusting plate 2 and corresponds to the position of the perforation 21. At this time, the mounting groove 42 on the mounting rod 4 can be used to install the spring 45. Spring 45 pushes the arc-shaped clamping plate 44. One end of the arc-shaped clamping plate 44 is slidably limited on the mounting rod 4 by the slide rod 43. After being pushed by spring 45, the arc-shaped clamping plate 44 can support itself on the outer wall of one of the support blocks 24, so that the support block 24 can correspond to the injection end at the center of the bottom of the liquid dispensing component 41. At the same time, when the position of the support block 24 is adjusted by rotating the adjusting plate 2, the arc-shaped clamping plate 44 can retract to make way for the rotational displacement of the support block 24, and can return to its original position under the support of spring 45. After the rotation and adjustment of each support block 24, the device can ensure that each support block 24 can be rotated sequentially and then positioned. The device corresponds to the liquid dispensing component 41, and the first clearance hole 31 on the sealing ring 3 allows the liquid dispensing component 41 to inject diluents such as physiological saline for dilution. After injection, the test tube can be moved below the sealing ring 3 by continuously rotating the adjusting plate 2. When it is rotated to the position where the second clearance hole 32 is opened, the sealing head can be installed at the top opening through the second clearance hole 32 to seal it, and it can be removed through the second clearance hole 32. This allows the device to inspect and dilute the test tubes in sequence, avoiding confusion, and enabling each test tube to be quickly aligned with the liquid dispensing component 41 to prevent deviation and affect the normal injection of diluent.

[0018] The base frame 1 and the support ring 11 are connected by a fixing rod 12. Several locking rods 13 are fixedly connected to the top of the support ring 11. The outer wall of the sealing ring 3 is fixedly connected to a mounting plate 33 that engages with the locking rods 13. The base frame 1 and the support ring 11 are connected by a fixing rod 12, so that the support ring 11 is fixedly mounted above the base frame 1, so that the support ring 11 supports and limits the outer wall of the adjusting plate 2, so that the adjusting plate 2 rotates steadily on the inner wall of the support ring 11. When the sealing ring 3 is used to protect the blood sample, the several locking rods 13 fixedly connected to the top of the support ring 11 can engage the mounting plate 33 with the locking rods 13, so that the sealing ring 3 is fixed above the adjusting plate 2.

[0019] A support plate 26 is fixedly connected to the inner wall of the base frame 1. A rotating shaft 25 is fixedly connected to the top of the support plate 26. The rotating shaft 25 is rotatably connected to the bottom of the connecting rod 22. The support plate 26 fixedly connected to the inner wall of the base frame 1 can support the rotating shaft 25. By rotatably connecting the bottom of the rotating shaft 25 to the bottom of the connecting rod 22, the rotating shaft 25 can support the bottom of the connecting rod 22 without affecting its position adjustment of the test tube.

[0020] The support block 24 is connected to the connecting rod 22 by a support frame 23, and a rotating rod 221 is installed at the center of the adjusting plate 2. The support block 24 is connected to the connecting rod 22 by a support frame 23, so that the support block 24 can be fixed at the position of the through hole 21 opened in the upper adjusting plate 2, ensuring the stability of the test tube installation.

[0021] An "L"-shaped rod 441 is fixedly connected to the bottom end of the arc-shaped plate 44. The "L"-shaped rod 441 is slidably connected to the mounting rod 4. One end of the spring 45 is fixedly connected to the inner wall of the mounting groove 42. The "L"-shaped rod 441 fixedly connected to the bottom end of the arc-shaped plate 44 is used to limit the arc-shaped plate 44 to slide horizontally when the arc-shaped plate 44 slides under the action of the sliding rod 43 and the spring 45, so that the arc-shaped plate 44 can be fixedly connected to the mounting rod 4 under the limitation of the sliding connection of the "L"-shaped rod 441 and the mounting rod 4, so that the arc-shaped plate 44 can be supported and positioned on the outer wall of the support block 24, and the position of the support block 24 can be positioned.

[0022] The working principle and usage process of this utility model are as follows: The blood sample to be diluted is loaded into a test tube. The test tube is installed through the perforation 21 on the adjusting plate 2, so that the bottom of the test tube is supported on the support block 24. At this time, the support ring 11 limits the outer wall of the top of the test tube. The sealing ring 3 is installed above the adjusting plate 2 by engaging the mounting plate 33 with the locking rod 13 to protect the blood inside the test tube. The liquid addition component 41 is installed on the mounting rod 4. The adjusting plate 2 is rotated to adjust the position of the test tube. During the process, the arc-shaped locking plate 44 retracts under the action of the spring 45 to adjust the clearance. After adjustment, the arc-shaped locking plate 44 returns to its original position and supports the outer wall of the support block 24, ensuring that the support block 24 corresponds to the bottom injection end of the liquid addition component 41. Physiological saline or other diluents are injected into the test tube through the first clearance hole 31 for dilution. The adjusting plate 2 is rotated further to rotate the test tube to the position of the second clearance hole 32. The sealing head is installed and sealed through the second clearance hole 32. Then, the diluted test tube is removed.

[0023] Although the specific embodiments of this utility model have been described and explained in detail above, it should be noted that various changes and modifications can be made to the above embodiments, but these will not depart from the spirit of this utility model and the scope of the appended claims.
