Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a batch cleaning and disinfection device for medical testing tubes. Background Technology

[0002] Medical laboratory test tubes come into direct contact with biological samples such as blood and bodily fluids, and may carry pathogens such as bacteria and viruses. If cleaning is not thorough, residual microorganisms can cause cross-contamination when the test tubes are reused. Using hot water spray to clean the inside of the test tubes allows for batch cleaning of test tubes.

[0003] In the existing technology, when cleaning test tubes in batches, the fixed position of the cleaning spray makes it impossible to fully clean the outer wall of the test tubes, resulting in poor cleaning effect on the outer wall of the test tubes and residual stains.

[0004] In summary, the problem of inadequate cleaning of the outer walls of test tubes during batch cleaning by fully automated medical cleaning machines, resulting in poor cleaning and residual stains, has become a pressing technical challenge for those skilled in the art. Therefore, it is necessary to propose a batch cleaning and disinfection device for medical laboratory test tubes. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a batch cleaning and disinfection device for medical test tubes. An air-blowing assembly drives a rotating sleeve to rotate, causing the test tubes to rotate during cleaning. This rotation increases the spray area on the outer wall of the test tubes, thereby thoroughly cleaning the outer wall and improving the cleaning effect.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: A batch cleaning and disinfection device for medical test tubes includes a test tube rack and a cleaning rack, with an adjustment component between the test tube rack and the cleaning rack for adjusting the position of the cleaning rack. The test tube rack contains a rotating component for driving the test tubes to rotate. The cleaning rack contains a cleaning component for batch cleaning the test tubes, a driving component for driving the cleaning component, a spraying component for spraying the outer wall of the test tubes, an air blowing component for blowing the rotating component to rotate, a storage component for storing cleaning solution, a conveying component for conveying cleaning solution, and a collection component for collecting cleaning solution. The rotating component includes several rotating sleeves, each rotating sleeve rotatably engaging with the test tube rack. Each rotating sleeve is fixedly connected with a fan blade, which communicates with the air blowing component. Each rotating sleeve contains an elastic component for clamping the test tubes.

[0007] The technical principle of the above solution is as follows: The test tube is clamped by an elastic component; the air-blowing component drives the rotating sleeve to rotate, thereby rotating the test tube; the cleaning component thoroughly cleans the inner wall of the test tube; and the spraying component sprays and cleans the outer wall of the rotating test tube, thus improving the cleaning efficiency. A conveying component delivers cleaning fluid to the cleaning and spraying components, and a collecting component collects the sprayed cleaning fluid.

[0008] The above approach has the following beneficial effects: 1. This invention utilizes the relative motion between the cleaning component and the inner wall of the test tube as the test tube rotates. Combined with the rinsing action of the cleaning solution, it can efficiently remove residues from the tube wall. The spray component performs a circular spray on the outer wall of the rotating test tube, using centrifugal force to enhance the stain removal effect and solve the problem of dead zones in traditional fixed spray systems. An elastic component adapts to test tubes of different sizes, ensuring rotational stability and preventing test tube displacement or breakage during the cleaning process.

[0009] 2. The present invention blows air onto the rotating sleeve through the air blowing component, thereby driving the rotating sleeve and fan blades to rotate, which in turn drives the test tube to rotate, improving the cleaning efficiency of the test tube when cleaning the outer wall and reducing dead corners in the cleaning of the outer wall of the test tube.

[0010] 3. The present invention forms a closed loop by using a storage component and a collection component. The storage component stores the cleaning fluid, and the collection component collects the cleaning fluid, thereby reducing the pollution of the cleaning fluid after use.

[0011] Furthermore, the elastic component includes several springs, each of which is fixedly connected to the inner wall of the rotating sleeve, and the other end of each spring is fixedly connected to a fixing plate.

[0012] Beneficial effects: The spring force allows the fixing plate to fit snugly against the test tube, reducing slippage of the test tube during rotation and improving the stability of the test tube during the cleaning process.

[0013] Furthermore, the drive assembly includes a drive component and a controller. The controller controls the operation of the drive component. The drive component is fixedly connected to the top of the cleaning rack. The output shaft of the drive component passes through the cleaning rack and is coaxially fixedly connected to a main gear. The main gear is rotatably engaged with the bottom of the cleaning rack. The main gear is circumferentially meshed with several driven gears, all of which are rotatably engaged with the bottom of the cleaning rack.

[0014] Beneficial effects: Through the meshing transmission between the main gear and multiple driven gears, synchronous drive and efficient operation of the cleaning components are achieved. Driven energy is directly converted into the rotational power of the cleaning components, reducing energy loss.

[0015] Furthermore, the cleaning assembly includes several rotating rods, each fixedly connected to the side away from the gear and away from the cleaning frame. Each rotating rod is circumferentially fixed with a brush. Each rotating rod has a cleaning chamber and several cleaning ports, all of which communicate with the cleaning chamber.

[0016] Beneficial effects: When the rotating rod rotates, the brush removes stubborn stains from the inner wall of the test tube through mechanical friction. At the same time, the cleaning liquid in the cleaning chamber is sprayed through the circumferentially distributed cleaning ports to form a spiral liquid flow, which rinses the tube wall after brushing in real time, improving the cleaning effect of the inner wall of the test tube.

[0017] Furthermore, the spray assembly includes a spray column, which is fixedly connected to the side of the main gear away from the cleaning frame. The spray column has a cavity and several spray holes, all of which are connected to the cavity.

[0018] Beneficial effects: The tangential velocity generated by the rotation of the spray column and the axial rotation of the test tube form a compound motion trajectory, causing the cleaning liquid to impact the tube wall in a spiral trajectory, effectively removing biological sample residues adhering to the outer wall of the test tube.

[0019] Furthermore, the conveying assembly includes a first rotating disk, and the output shaft of the drive component at the end away from the cleaning frame is coaxially and fixedly connected to the first rotating disk. A first piston cylinder is fixedly connected to the top of the cleaning frame. The first piston cylinder has an inlet and an outlet. A first one-way valve is fixedly connected to both the inlet and the outlet. The inlet is connected to a storage component, and the outlet is connected to a delivery pipe. The cavity and the cleaning chamber are both connected to the end of the delivery pipe away from the outlet. A first piston head is slidably fitted inside the first piston cylinder. A first push rod is hinged to the end of the first piston head away from the inlet. The end of the first push rod away from the first piston head is eccentrically hinged to the first rotating disk.

[0020] Beneficial effects: The rotational motion of the driving component is converted into the reciprocating linear motion of the first piston head by the first rotating disk, and the first one-way valve is used to deliver the cleaning fluid, thereby simultaneously delivering the cleaning fluid to the outer and inner walls of the test tube for cleaning, which improves the cleaning efficiency of the test tube.

[0021] Furthermore, the storage component includes a storage tank, which is fixedly connected to the top of the cleaning rack. The storage tank has an inlet and an outlet, with the outlet connected to the liquid inlet.

[0022] Beneficial effects: Storing the cleaning solution in a storage tank improves the stability of the cleaning solution delivery and allows medical staff to replenish the cleaning solution in a timely manner, reducing the possibility of insufficient cleaning solution leading to poor tube cleaning results.

[0023] Furthermore, the air blowing assembly includes a second piston cylinder and a second rotating disk. The second rotating disk is rotatably engaged with the top of the cleaning frame. A fixing rod is fixedly connected to one end of the second rotating disk near the cleaning frame, and the fixing rod passes through the cleaning frame and is fixedly connected to a driven gear. The second piston cylinder is fixedly connected to the top of the cleaning frame. The second piston cylinder has an air inlet and an air outlet. A second one-way valve is fixedly connected to both the air inlet and the air outlet. An air supply pipe is connected to the air outlet. The end of the air supply pipe away from the air outlet is located on the side of the fan blade, and is used to supply gas to blow the fan blade to rotate. A second piston head is slidably engaged inside the second piston cylinder. A second push rod is hinged to the end of the second piston head away from the air inlet. The end of the second push rod away from the second piston head is eccentrically hinged to the second rotating disk.

[0024] Beneficial effects: By sliding the second piston head inside the second piston cylinder, the airflow supply is stabilized, allowing the fan blades to rotate stably, thereby improving the stability of the test tube during rotation.

[0025] Furthermore, the adjustment assembly includes several telescopic components, and the controller is used to control the operation of the telescopic components. All telescopic components are fixedly connected to the test tube rack, and the output shafts of the telescopic components are fixedly connected to the cleaning rack.

[0026] Beneficial effect: The distance between the cleaning rack and the test tube rack can be adjusted by the telescopic component, which helps to improve the portability of test tubes when taking them out and putting them in.

[0027] Furthermore, the collection component includes a collection box, which is fixedly connected to the bottom of the test tube rack, and has a collection port on the top of the collection box.

[0028] Beneficial effects: The collection box collects the cleaning solution after spraying, reducing the pollution of the environment caused by the cleaning solution.

[0029] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0035] The following detailed description illustrates the specific implementation method: Example 1:

[0036] As attached Figure 1 The image shows a medical testing tube batch cleaning and disinfection device, comprising a tube rack 1 and a cleaning rack 2, with an adjustment component between the tube rack 1 and the cleaning rack 2 for adjusting the position of the cleaning rack 2. The tube rack 1 contains a rotating component for rotating the tubes. The cleaning rack 2 includes a cleaning component for batch cleaning the tubes, a driving component for driving the cleaning component, a spraying component for spraying the outer wall of the tubes, an air blowing component for driving the rotating component, a storage component for storing cleaning solution, a conveying component for conveying the cleaning solution, and a collection component for collecting the cleaning solution.

[0037] Specifically, such as Figure 1 and Figure 4 As shown, the rotating assembly includes several rotating sleeves 14, each of which is rotatably engaged with the test tube rack 1. Each rotating sleeve 14 is screwed and fixedly connected to a fan blade 13, which communicates with the air blowing assembly. Each rotating sleeve 14 contains an elastic component for clamping the test tubes. The elastic component includes several springs 21, each spring 21 is screwed and fixedly connected to the inner wall of the rotating sleeve 14, and the other end of each spring 21 is screwed and fixedly connected to a fixing plate 22.

[0038] When the test tube is placed into the rotating sleeve 14, it squeezes the fixing plate 22, thereby compressing the spring 21. After the test tube is placed, the fixing plate 22 clamps the test tube under the elastic force of the spring 21, thus improving the stability of the test tube during rotation. The air blowing assembly delivers gas to the fan blade 13, thereby driving the fan blade 13 to rotate. The rotation of the fan blade 13 drives the rotation of the rotating sleeve 14, which in turn drives the rotation of the test tube.

[0039] Specifically, in combination Figure 2As shown, the drive assembly includes a drive component and a controller. In this embodiment, the drive component is a dual-head motor 19. The controller is used to control the operation of the dual-head motor 19. The dual-head motor 19 is bolted to the top of the cleaning frame 2. The output shaft of the dual-head motor 19 passes through the cleaning frame 2 and is coaxially bolted to a main gear 16. The main gear 16 is rotatably engaged with the bottom of the cleaning frame 2. The main gear 16 is circumferentially meshed with several driven gears 15, all of which are rotatably engaged with the bottom of the cleaning frame 2. The cleaning assembly includes several rotating rods 17, each of which is screwed to the side of the driven gears 15 away from the cleaning frame 2. Each rotating rod 17 is circumferentially screwed to a brush 12. Each rotating rod 17 has a cleaning chamber and several cleaning ports, all of which communicate with the cleaning chamber. The spray assembly includes a spray column 11, which is screwed to the main gear 16 on the side away from the cleaning frame 2. The spray column 11 has a cavity inside and several spray holes on it, all of which are connected to the cavity.

[0040] After the dual-head motor 19 is started, it drives the main gear 16 to rotate. The rotation of the main gear 16 synchronously drives the meshing driven gear 15 to rotate. When the main gear 16 rotates, it drives the spray column 11 to rotate coaxially. At this time, the cleaning solution in the storage component can be sprayed out through the spray holes under the conveying component, thus cleaning the outer wall of the test tube. With the rotation of the test tube, the outer wall can be cleaned from all directions. When the driven gear 15 rotates, it coaxially drives the rotating rod 17 to rotate. The rotation of the rotating rod 17 drives the brush 12 to rotate, thus cleaning the inner wall of the test tube. With the rotation of the rotating rod 17, under the conveying action of the conveying component, the cleaning solution is sprayed out through the cleaning port, thus spraying and cleaning the inner wall of the test tube. Through spray cleaning and the physical cleaning of the brush 12, the cleaning efficiency of the inner wall of the test tube is improved.

[0041] Specifically, in combination Figure 3 As shown, the conveying assembly includes a first rotating disk 4. The output shaft of a dual-head motor 19, located away from the cleaning frame 2, is coaxially bolted to the first rotating disk 4. A first piston cylinder 6 is bolted to the top of the cleaning frame 2. The first piston cylinder 6 has an inlet and an outlet. A first one-way valve is screwed into both the inlet and outlet. The inlet connects to a storage assembly, and the outlet connects to a delivery pipe. Both the cavity and the cleaning chamber are connected to the end of the delivery pipe away from the outlet. A first piston head 18 is slidably fitted inside the first piston cylinder 6. A first push rod 5 is hinged to the end of the first piston head 18 away from the inlet. The end of the first push rod 5 away from the first piston head 18 is eccentrically hinged to the first rotating disk 4. The storage assembly includes a storage tank 3, which is bolted to the top of the cleaning frame 2. The storage tank 3 has a feed inlet and a discharge outlet, with the discharge outlet connected to the feed inlet.

[0042] When the dual-head motor 19 is running, it coaxially drives the first rotating disk 4 to rotate. The rotation of the first rotating disk 4 drives the first push rod 5 to move back and forth. The reciprocating movement of the first push rod 5 drives the first piston head 18 to slide back and forth in the first piston cylinder 6. As the first piston head 18 slides, the cleaning liquid in the storage tank 3 enters the first piston cylinder 6 through the discharge port and the inlet port. Then, it is transported to the cavity and the cleaning chamber through the liquid delivery pipeline. It is sprayed onto the inner and outer walls of the test tube through the cleaning port and the spray hole, respectively, to thoroughly clean the test tube.

[0043] Specifically, the air blowing assembly includes a second piston cylinder 7 and a second rotating disk 9. The second rotating disk 9 is rotatably engaged with the top of the cleaning frame 2. A fixing rod is bolted to one end of the second rotating disk 9 near the cleaning frame 2, and the fixing rod passes through the cleaning frame 2 and is bolted to the driven gear 15. The second piston cylinder 7 is bolted to the top of the cleaning frame 2. The second piston cylinder 7 has an air inlet and an air outlet. A second one-way valve is screwed into both the air inlet and the air outlet. The air outlet is connected to an air supply pipe. The end of the air supply pipe away from the air outlet is located on the side of the fan blade 13, and is used to supply gas to blow the fan blade 13 to rotate. A second piston head is slidably engaged inside the second piston cylinder 7. A second push rod 8 is hinged to the end of the second piston head away from the air inlet. The end of the second push rod 8 away from the second piston head is eccentrically hinged to the second rotating disk 9.

[0044] When the driven gear 15 rotates, it drives the second rotating disk 9 to rotate. The rotation of the second rotating disk 9 drives the second push rod 8 to reciprocate. The reciprocating movement of the second push rod 8 drives the second piston head to slide back and forth inside the second piston cylinder 7. At this time, outside air enters the second piston cylinder 7 through the second one-way valve of the air inlet, and then is delivered to the fan blade 13 through the air outlet and air supply pipe, blowing the fan blade 13 to rotate, which in turn drives the rotating sleeve 14 to rotate.

[0045] The adjustment assembly includes several telescopic components. In this embodiment, the telescopic component is selected as an electric telescopic rod 10. The controller is used to control the operation of the electric telescopic rod 10. The electric telescopic rod 10 is bolted to the test tube rack 1. The output shaft of the electric telescopic rod 10 is bolted to the cleaning rack 2.

[0046] The specific implementation process is as follows: Figure 1 For example, medical staff can first control the extension of the electric telescopic rod 10 via the controller, thereby adjusting the position of the washing rack 2, raising the position of the washing rack 2, and then placing the test tubes into the test tube rack 1. Figure 4As shown, the test tube is fixed by the fixing plate 22. After the test tube is placed in, the controller can be used to control the electric telescopic rod 10 to retract, allowing the brush 12 to enter the test tube. Then, medical staff can inject cleaning fluid through the inlet of the storage box 3. Subsequently, the controller controls the operation of the dual-head motor 19. When the dual-head motor 19 is running, it drives the main gear 16 to rotate, which in turn drives the driven gear 15 to rotate, thereby causing the spray column 11 and the rotating rod 17 to rotate.

[0047] by Figure 2 and Figure 3 For example, when the rotating rod 17 rotates, it drives the brush 12 to rotate on the inner wall of the test tube, physically cleaning the inner wall. As the dual-head motor 19 operates, it drives the first rotating disk 4 to rotate, which in turn drives the first piston head 18 to slide back and forth in the first piston cylinder 6 via the first push rod 5. This allows the cleaning solution in the storage tank 3 to enter the cavity and cleaning chamber through the first piston cylinder 6, and then spray the inner and outer walls of the test tube synchronously through the spray holes and cleaning ports.

[0048] When gear 15 is running, it will also drive the second rotating disk 9 to rotate. The rotation of the second rotating disk 9 will drive the second push rod 8 to push the second piston head to slide back and forth in the second piston cylinder 7. At this time, the outside air will be continuously transported to the fan blade 13 through the second piston cylinder 7, thereby driving the fan blade 13 to rotate.

[0049] When the fan blade 13 rotates, it drives the rotating sleeve 14 to rotate, which in turn drives the test tube to rotate. When spraying the test tube through the spray hole, it can spray the outer wall of the test tube from all directions, reducing spray dead zones. Furthermore, the rotation speed of the fan blade 13 driving the rotating sleeve 14 is not the same as the rotation speed of the rotating rod 17, so that the test tube and the brush 12 will not rotate synchronously.

[0050] The present invention utilizes the sliding of the second piston head within the second piston cylinder 7 to continuously deliver gas to the fan blade 13, thereby driving the rotating sleeve 14 to rotate. The rotation of the rotating sleeve 14 causes the test tube to rotate, thus enabling the cleaning liquid sprayed from the spray hole to thoroughly clean the outer wall of the test tube and the cleaning liquid sprayed from the cleaning port to thoroughly clean the inner wall of the test tube. Combined with the physical cleaning of the brush 12, the cleaning effect and efficiency of the test tube are improved.

[0051] Example 2:

[0052] like Figure 1 As shown, the difference from the above embodiment is that the collection component includes a collection box 20, which is bolted to the bottom of the test tube rack 1, and the collection box 20 has a collection port on the top.

[0053] The specific implementation process is as follows: After the cleaning liquid is sprayed out of the spray hole and the cleaning port, the cleaning liquid will fall into the collection box 20 through the test tube rack 1 and the collection port, and be collected by the collection box 20, thereby reducing the pollution of the cleaning liquid to the external environment and reducing cross-interference.

[0054] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
