Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a silent and visual test tube rack that automatically shakes blood samples. Background Technology

[0002] Automatic blood sample shaker racks are key auxiliary equipment in clinical testing, blood analysis, and biomedical experiments. Their core function is to simulate manual shaking to achieve uniform mixing of blood samples with anticoagulants / coagulants, or to prevent blood components (such as red blood cells and platelets) from settling, thus providing qualified samples for subsequent blood routine tests, biochemical analyses, and immunoassays. In existing technologies, manual shaking of blood samples is often inefficient, and excessive force during mixing can easily cause hemolysis, resulting in unqualified blood samples.

[0003] To address the aforementioned deficiencies, existing technology (Chinese patent No. CN221965093U, published on 2024-11-08) provides an automatic shaking device to prevent blood collection tube specimens from coagulating. This device uses a drive motor to drive a swinging connector to swing, and the swinging connector is connected to a test tube rack, thereby causing the test tube rack to swing and automatically shaking the blood collection tubes placed in the test tube rack. This reduces the working time of medical staff and improves the efficiency of blood collection.

[0004] The above method has a single shaking method for the test tube, which can only swing back and forth around the rotation point. This makes it take a long time to mix the blood sample. In addition, the blood collection tube lacks a limiting component during shaking, and the blood collection tube is prone to sliding and colliding with the placement frame during shaking, which can cause damage to the blood collection tube. Utility Model Content

[0005] The purpose of this invention is to provide a silent and visual test tube rack for automatically shaking blood samples, in order to solve the problems mentioned in the background art. In the process of use, the existing test tube racks for automatically shaking blood samples have a single shaking method, which can only swing back and forth around the rotation point, resulting in a long time for the blood sample to be mixed evenly. In addition, the blood collection tubes lack limiting parts during shaking, which can easily cause slippage and collision, thereby damaging the blood collection tubes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a silent and visual test tube rack for automatically shaking blood samples, including a base, side plates symmetrically installed on both sides of the top of the base, a mounting frame between the side plates, and a set of tube placement racks for placing blood collection tubes fixed at equal intervals in the middle of the mounting frame;

[0007] A swing component is provided between the side of the side plate and the outside of the mounting frame, and the swing component drives the mounting frame to move up and down while swinging back and forth.

[0008] A pressure plate is symmetrically and rotatably connected to the top inner side of the mounting frame. The pressure plate abuts against the top of the blood collection tube. A reinforcing fixing component is provided in the inner wall of the blood collection tube penetration point on the tube placement frame. The reinforcing fixing component remains stable and prevents slippage when the blood collection tube swings.

[0009] Furthermore, the swing assembly includes electric push rods symmetrically mounted on the top of the base. The top of the electric push rods is fixedly connected to a fixed block, and the side of the fixed block is rotatably connected to the middle of the mounting frame. Guide grooves are symmetrically opened on the outer sides of both sides of the mounting frame, and crossbars are slidably connected in the guide grooves. The crossbars are fixed to the side of the side plate.

[0010] Furthermore, the guide groove is configured as a "V" shaped structure, and the mounting bracket forms a rapid shaking structure through an electric push rod, a crossbar, and the guide groove.

[0011] Furthermore, a torsion spring is installed between the shaft portion of the pressure plate and the side plate, and a first magnetic sheet is installed on the top of the pressure plate. The magnetic poles of the first magnetic sheet and the second magnetic sheet are opposite. The second magnetic sheet is installed on the center line of the side of the side plate. The pressure plate forms a closed and retractable structure through the first magnetic sheet and the second magnetic sheet.

[0012] Furthermore, the reinforcing fixing component includes a groove formed at the bottom of the inner side of the mounting frame, a horizontal plate slidably connected inside the groove, and a support plate equally spaced on the top of the horizontal plate. The support plate is configured as a hollow hemispherical structure, and the bottom of the blood collection tube abuts against the top of the support plate.

[0013] Furthermore, a spring is installed at the bottom of the horizontal plate, and piezoelectric plates are installed at the bottom of both the spring and the bottom of the groove. The piezoelectric plates at the bottom of the spring and the piezoelectric plates at the bottom of the groove are pressed and in contact, and the electrical charge generated by the piezoelectric plates is supplied to the electromagnet through a battery.

[0014] Furthermore, the electromagnets are installed at equal intervals in the inner wall of the tube placement frame, and a contact plate is slidably connected to the inner wall of the passage of the blood collection tube on the tube placement frame. The contact plate is set with an arc-shaped structure, and a magnetic block is fixed to the outside of the contact plate. The magnetic block and the electromagnet are arranged opposite to each other.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This silent, visually-enabled blood sample shaker utilizes a combined swing and shake mechanism with multi-dimensional fixation and protection. The swinging component moves the blood collection tubes up and down and swings back and forth, while the reinforced fixation component and pressure plate provide dual limiting. Sound-insulating materials and a low-noise motor effectively reduce operating noise. Colored LED strips visually display the equipment status (blue for standby, green for operation, and red for alarm), providing a clear and intuitive human-machine interface. This solves the problems of traditional equipment, such as a single shaking mode, low shaking efficiency, and easy slippage and damage to the blood collection tubes, achieving efficient and uniform mixing of blood samples with safe protection.

[0017] 1. Furthermore, as the mounting frame moves up and down with the electric push rod, the inclined structure of the guide groove forces the mounting frame to swing back and forth around the rotation point of the fixed block: during the upward movement, the mounting frame swings forward along the inclined direction of the guide groove; during the downward movement, it swings backward in the opposite direction along the guide groove, simulating the natural trajectory of manual shaking, so that the blood sample in the blood collection tube can be shaken more quickly and at the same time improve the shaking efficiency.

[0018] 2. Furthermore, after the blood collection tube is inserted into the tube holder, the pressure plate automatically presses down under the action of the torsion spring, and its bottom abuts against the top of the blood collection tube, which plays a role in pressing and limiting, preventing the blood collection tube from jumping slightly when shaken. Later, the first magnetic piece on the pressure plate will be attracted and fixed by the second magnetic piece, and rotated to a vertical position, which will not hinder the normal placement and removal of the blood collection tube.

[0019] 3. Furthermore, the weight of the blood collection tube itself presses the horizontal plate downwards, compressing the spring at the bottom of the horizontal plate. The elastic force of the spring reacts to the horizontal plate, keeping the support plate in contact with the bottom of the blood collection tube. Even if there are bumps during shaking, the impact force can be absorbed by the spring's buffer, preventing the bottom of the blood collection tube from making hard contact with the mounting frame.

[0020] 4. Furthermore, the piezoelectric plates installed at the bottom of the spring and the bottom of the groove squeeze each other, and the generated electrical energy is stored in the built-in battery to power the electromagnet. The electromagnet generates a magnetic field, and the magnetic block fixed to the outside of the arc-shaped contact plate that is slidably connected to the inner wall of the tube holder generates a magnetic repulsion force, which drives the contact plate to move closer to the side wall of the blood collection tube and fit tightly.

[0028] 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.

[0029] Example 1: Please refer to Figure 1 - Figure 2 The present invention provides the following technical solution: a silent and visual test tube rack for automatically shaking blood specimens, including a base 1, side plates 2 symmetrically installed on both sides of the top of the base 1, a mounting frame 5 between the side plates 2, a set of tube placement racks 6 for placing blood collection tubes fixed at equal intervals in the middle of the mounting frame 5, a swing component between the side of the side plate 2 and the outside of the mounting frame 5, and the swing component drives the mounting frame 5 to move up and down while swinging back and forth, a pressure plate 9 symmetrically rotated and connected to the inner side of the top of the mounting frame 5, the pressure plate 9 abutting against the top of the blood collection tube, and a reinforcing fixing component is provided in the inner wall of the blood collection tube penetration point on the tube placement rack 6, and the reinforcing fixing component remains stable and avoids slippage when the blood collection tube swings.

[0030] like Figure 1 - Figure 2As shown, during use, the blood collection tube is placed into the through-hole of the tube placement frame 6 on the mounting frame 5. A sensor is installed at the through-hole of the tube placement frame 6. After all the blood collection tubes are placed, the electric push rod 3 moves. During the entire shaking process, the swing component, the pressure plate 9, and the reinforcing fixing component work closely together: the swing component provides compound shaking power to ensure that the blood sample is mixed quickly and evenly; the pressure plate 9 uses a torsion spring 10 and a magnetic sheet to limit the top of the blood collection tube and prevent it from falling upwards; the reinforcing fixing component uses a bottom spring 16 to buffer and magnetically clamp the side wall to prevent the bottom of the blood collection tube from sliding and colliding with the side wall. After the shaking is complete, the electric push rod 3 returns to its initial position, the electromagnet 20 is de-energized, the contact plate 18 returns to its original position after the magnetic attraction disappears, and the pressure plate 9 compresses the torsion spring 10 when manually flipped upwards, so that the blood collection tube can be easily removed. This achieves convenient operation of automatic shaking, safe fixation, and easy removal and placement. At the same time, sound insulation materials and low-noise motors can be used to control the operating noise of the equipment to an extremely low level (such as <40 decibels). Color LED light strips are used to intuitively display the status of the equipment through different colors (blue for standby, green for operation, and red for alarm), realizing a human-machine interaction that is "instantly clear".

[0031] Example 2:

[0032] Based on Example 1, a mechanism for combining shaking of blood collection tubes to improve shaking efficiency is also disclosed. Please refer to [link / reference]. Figure 2 - Figure 3 As shown, its specific structure is as follows: The swing assembly includes an electric push rod 3 symmetrically installed on the top of the base 1. The top of the electric push rod 3 is fixedly connected to the fixed block 4. The side of the fixed block 4 is rotatably connected to the middle of the mounting frame 5. Guide grooves 8 are symmetrically opened on the outer sides of both sides of the mounting frame 5. A crossbar 7 is slidably connected in the guide groove 8. The crossbar 7 is fixed to the side of the side plate 2. The guide groove 8 is set as a "V" shaped structure. The mounting frame 5 forms a rapid shaking structure through the electric push rod 3, the crossbar 7 and the guide groove 8.

[0033] refer to Figure 2 - Figure 3As shown, during use, after the electric push rods 3 symmetrically installed on the top of the base 1 are started, their piston rods extend and retract vertically, driving the fixed block 4 fixed at the top to rise and fall synchronously. The side of the fixed block 4 is rotatably connected to the middle of the mounting frame 5, thereby pulling the mounting frame 5 to move up and down as a whole. The extension and retraction rate and stroke of the electric push rods 3 can be adjusted according to the type of specimen. For example, slow rise and slow fall are used for blood routine specimens, and fast rise and fast fall are used for blood culture specimens to adapt to different mixed needs. The guide groove 8 on the outside of the mounting frame 5 is slidably connected to the crossbar 7 fixed on the side of the side plate 2. When the mounting frame 5 moves with the electric push rod 3, the piston rod extends and retracts vertically. When the push rod 3 moves up and down, the inclined structure of the guide groove 8 forces the mounting frame 5 to swing back and forth around the rotation point of the fixed block 4: during the upward movement, the mounting frame 5 swings forward along the inclined direction of the guide groove 8; during the downward movement, it swings backward in the opposite direction along the guide groove 8, shaking the specimen 8 times. This combined up-and-down and back-and-forth motion can simulate the natural trajectory of manual shaking, making the blood specimen in the blood collection tube shaken more quickly and significantly shortening the shaking time. To facilitate operation by medical staff, an operation example table can be pasted on the outside of the side plate 2 to record the shaking operation requirements for blood specimen tubes of different colors.

[0034] Example 3:

[0035] Based on Embodiment 2, a mechanism for fixing the top of the blood collection tube to prevent it from shaking and falling off is also disclosed. Please refer to the figure. Its specific structure is as follows: A torsion spring 10 is installed between the shaft of the pressure plate 9 and the side plate 2. A first magnetic sheet 11 is installed on the top of the pressure plate 9. The magnetic poles of the first magnetic sheet 11 and the second magnetic sheet 12 are opposite. The second magnetic sheet 12 is installed on the center line of the side of the side plate 2. The pressure plate 9 forms a closed and retractable structure through the first magnetic sheet 11 and the second magnetic sheet 12.

[0036] During use, the torsion spring 10 installed between the shaft of the pressure plate 9 and the side plate 2 is in a torsional storage state in its natural state, providing pressure to the pressure plate 9 in the direction of the blood collection tube. When the blood collection tube is inserted into the tube holder 6, the pressure plate 9 automatically presses down under the action of the torsion spring 10, and its bottom abuts against the top of the blood collection tube, which plays a role in pressing and limiting, preventing the blood collection tube from jumping slightly when shaken. When removing the blood collection tube later, the two pressure plates 9 are rotated, and the first magnetic piece 11 on the pressure plate 9 will be attracted and fixed to the second magnetic piece 12. Rotating to a vertical position will not hinder the normal placement and removal of the blood collection tube.

[0037] Example 4:

[0038] Based on Embodiment 3, a mechanism for fixing the bottom and sidewall of the blood collection tube to prevent sliding and collision is also disclosed. Please refer to the figure. Its specific structure is as follows: The reinforcing fixing component includes a groove 13 formed in the bottom of the inner side of the mounting frame 5. A horizontal plate 14 is slidably connected inside the groove 13. A support plate 15 is installed at equal intervals on the top of the horizontal plate 14. The support plate 15 is set as a hollow hemispherical structure, and the bottom of the blood collection tube abuts against the top of the support plate 15. A spring 16 is installed at the bottom of the horizontal plate 14. Piezoelectric plates 17 are installed at the bottom of both the spring 16 and the groove 13. The piezoelectric plates 17 at the bottom of the spring 16 and the piezoelectric plates 17 at the bottom of the groove 13 are pressed and contacted. The electricity generated by the piezoelectric plates 17 is supplied to the electromagnets 20 through the battery. The electromagnets 20 are installed at equal intervals in the inner wall of the tube placement frame 6. A contact plate 18 is slidably connected to the inner wall of the passage of the blood collection tube on the tube placement frame 6. The contact plate 18 is set with an arc-shaped structure. A magnetic block 19 is fixed to the outside of the contact plate 18. The magnetic block 19 and the electromagnets 20 are arranged opposite to each other.

[0039] During use, the horizontal plate 14, which is slidably connected in the groove 13 at the bottom of the inner side of the mounting frame 5, has hollow hemispherical support plates 15 installed at equal intervals on its top, which are in close contact with the bottom of the blood collection tube. The weight of the blood collection tube itself presses the horizontal plate 14 downward, compressing the spring 16 at the bottom of the horizontal plate 14. The elastic force of the spring 16 reacts to the horizontal plate 14, keeping the support plate 15 in close contact with the bottom of the blood collection tube. Even if there are bumps during shaking, the impact force can be absorbed by the spring 16, preventing the bottom of the blood collection tube from making hard contact with the mounting frame 5. At the same time, the piezoelectric plate 17 installed at the bottom of the groove 13 and the spring 16 squeeze each other, and the generated electrical energy is stored inside. A battery is installed to power the electromagnets 20, enabling energy recovery. After the battery powers the electromagnets 20, which are installed at equal intervals on the inner wall of the tube holder 6, the electromagnets 20 generate a magnetic field. The magnetic block 19, which is fixed to the outside of the arc-shaped contact piece 18 that is slidably connected to the inner wall of the tube holder 6, generates a magnetic repulsion force, which drives the contact piece 18 to move closer to the side wall of the blood collection tube and fit tightly. The magnitude of the magnetic clamping force changes synchronously with the compression of the spring 16. The heavier the blood collection tube, the greater the compression of the spring 16, the more electricity the piezoelectric piece 17 generates, and the stronger the attraction of the electromagnet 20. This ensures that blood collection tubes of different specifications can be stably fixed, avoiding scratches or cracks caused by the side wall colliding with the tube holder 6 when shaking.

[0040] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0041] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
