Description

Technical Field

[0001] The present invention relates to the technical field of children's blood detection, in particular to a children's blood detector. Background Art

[0002] At present, the routine blood tests performed in hospitals are mainly three-category and five-category classification. This is for the classification of white blood cells. The three-category instrument can roughly divide white blood cells into three categories: large cells (neutrophils), intermediate cells (other white blood cells), and small cells (lymphocytes). The five-category instrument can divide white blood cells into five categories: neutrophils, lymphocytes, eosinophils, basophils, and monocytes. There is not much difference between the various instruments for the red blood cell and platelet systems.

[0003] Among them, pediatrics often use a five-category routine blood tester when conducting routine blood tests. When in use, medical staff need to manually shake the blood sample tube and place it under the test head in the test window. The test head is inserted into the blood sample tube to test the blood and display and print out the results. After the test, the test head is retracted into the body for processing. Therefore, the existing test can only rely on medical staff to perform the entire operation and conduct a single test tube test. While the test efficiency is low, it is not convenient to perform automatic testing in a closed environment, and it is easy to cause contamination of the blood sample. In addition, when the test head is retracted into the body, blood adheres to the outside of the test head and is easy to drip into the window, causing contamination. Therefore, we propose a children's blood detector to solve this existing technical defect. Summary of the Invention

[0022] (3) Beneficial effects

[0023] Compared with the prior art, the present invention provides a children's blood detector with the following advantages:

[0024] 1. The children's blood detector stores blood test tubes through the provided blood sample tube placement seat. After storage, the stored blood test tubes are rotated and mixed by cooperating with the driving component. After mixing is completed, the lifting component is used to push the blood sample tube placement seat to move and seal it in the circular sealing hole. In addition, the provided electric guide rail drives the sealing cover to move to seal the detection window, and then the blood tube cap is clamped by the rotation component and the clamping mechanism. After clamping, the rotary component drives the cap spiral to retract while cooperating with the lifting component to drive the blood sample tube placement seat downward. In a closed environment, the driving component is driven to open the placed blood test tubes one by one. Then, the driving component and the lifting component cooperate to insert the stored blood test tubes one by one into the detection head for automatic detection. Compared with the existing full-process operation by medical staff, the efficiency and safety of the detection are improved.

[0025] 2. The children's blood detector is equipped with an electric push rod. After the test, the electric push rod pushes the absorbent cotton on the U-shaped seat and inserts it into the outside of the test head. In conjunction with the upward movement of the test head, the absorbent cotton absorbs the blood on the outside of the test head to avoid blood dripping and causing contamination when the test head is moved into the detector body. After the absorbent cotton absorbs the blood, the electric push rod drives the absorbent cotton to move into the cleaning cylinder. In conjunction with the cleaning component, the cleaning liquid is sprayed from the nozzle to clean the absorbent cotton. The cleaned cleaning liquid is discharged into the liquid accumulation component for storage. After the cleaning is completed, the exhaust component discharges air into the nozzle to dry the absorbent cotton, which is convenient for multiple use of the absorbent cotton.

A sealing ring is fixed in the circular sealing hole 15 to ensure the sealing performance of the connection with the circular sealing disk 7.

[0040] The lifting assembly is also provided with a driving assembly for driving the blood sample tube placement seat 8 to rotate synchronously. The driving assembly includes a driving motor 11 fixedly mounted on the upper end surface of the support frame 6. The lower end surface of the blood sample tube placement seat 8 is fixedly connected to the rotating shaft 9 concentrically. The rotating shaft 9 passes through the bottom of the circular sealing disk 7 and is rotatably connected to the circular sealing disk 7. The other end of the rotating shaft 9 is rotatably connected to a driven gear disc 10 concentrically. The output end of the driving motor 11 is fixedly connected to a driving gear disc 12 engaged with the driven gear disc 10. By starting the driving motor 11 to drive the driving gear disc 12 to rotate, the engagement of the driving gear disc 12 with the driven gear disc 10 can be used to drive the blood sample tube placement seat 8 on the rotating shaft 9 to rotate, thereby shaking the blood in the blood sample test tube.

[0041] See also Figure 1 and Figures 7 to 10, an electric guide rail 16 is fixed to the right side of the detector body 1, and a sealing cover 17 for sealing the detection window 3 is fixed to the guide rail slide of the electric guide rail 16, and a sealing gasket is attached to the edge of the opening of the sealing cover 17 to ensure the sealing and docking effect of the sealing cover 17.

The clamping mechanism includes an electric push rod three 26 fixed to the front and rear side surfaces of the clamping seat 25. The push rod of the electric push rod three 26 is fixed with a clamping block 27 located in the clamping seat 25. The clamping block 27 is driven to move to the outside of the blood sample tube by the electric guide rail two 23, and then the electric push rod three 26 pushes the clamping block 27 to clamp the sealing cap of the blood sample tube. Finally, the servo motor 24 drives the clamping block 27 to rotate and unscrew the sealing cap of the blood sample tube, thereby realizing the opening of the sealing cap of the blood sample tube one by one.

[0042] A cleaning cylinder 18 is fixed to the right side of the sealing cover 17, and the left side of the cleaning cylinder 18 is connected to the sealing cover 17. An electric push rod 19 is fixed to the right side of the cleaning cylinder 18. A U-shaped seat 20 that passes through the cleaning cylinder 18 and the sealing cover 17 is fixed to the push rod of the electric push rod 19. A water-absorbing cotton 22 is detachably fixed to the opening of the U-shaped seat 20. A retaining ring 28 is fixed to the left opening of the sealing cover 17. The retaining ring 28 is concentric with the cleaning cylinder 18, and the inner diameter of the cleaning cylinder 18 is larger than the retaining ring 28. The inner diameter ensures that the sewage after cleaning is blocked by the retaining ring 28 to prevent the sewage from flowing out from the left opening of the cleaning cylinder 18. A slot 21 for inserting absorbent cotton 22 is provided on the left side of the U-shaped seat 20. The absorbent cotton 22 is U-shaped and is pushed by the electric push rod 19 to move the absorbent cotton 22 in the U-shaped seat 20 to the outside of the test head 4. It can absorb the blood attached to the outside of the test head 4 to prevent the test head 4 from dripping and causing contamination when it is moved into the detector body 1.

[0043] The upper surface of the cleaning cylinder 18 is connected to a nozzle 29, and the detector body 1 is provided with a cleaning component and an exhaust component connected to the nozzle 29. The cleaning component includes a cleaning liquid storage seat 30 fixedly mounted on the upper end surface of the right side of the detector body 1, and the right side of the cleaning liquid storage seat 30 is connected and fixed with a liquid suction pump 31. The liquid suction port of the liquid suction pump 31 is connected to the cleaning liquid storage seat 30. The upper end surface of the cleaning liquid storage seat 30 is open, and the opening is sealed by a cover, which is convenient for opening to replenish cleaning liquid inside.

The cleaning cylinder 18 is also provided with a liquid accumulation component for collecting the cleaning liquid, and the liquid accumulation component includes a liquid accumulation component connected to the lower end surface of the cleaning cylinder 18 The sewage after cleaning is discharged into the liquid storage seat 36 through the sewage hose 35. After the cleaning of the absorbent cotton 22 is completed, the air flow is ejected through the nozzle 29 on the exhaust hose 34 by the fan 33, thereby drying the cleaned absorbent cotton 22, which is convenient for repeated use of the absorbent cotton 22.

[0044] The control system of the entire children's blood detector is centrally controlled by PLC.

[0045] The cleaning solution usually consists of deionized water, a surfactant (such as polyethylene glycol), a buffer (such as phosphate buffer), and a preservative (such as sodium benzoate).

[0046] Deionized water: acts as a solvent, provides a clean base, and removes inorganic salts and impurities.

[0047] Surfactants: Reduce the surface tension of water, enhance wettability and permeability, and effectively remove protein and lipid residues.

[0048] Buffer: Maintains the pH value of the cleaning solution to prevent chemical damage to the detection head and sample.

[0049] Preservatives: Prevent the cleaning fluid from growing bacteria and mold during storage, extending its service life.

[0050] Specific recipe example:

[0051] Deionized water: 95%;

[0052] Polyethylene glycol (PEG): 3%;

[0053] Phosphate buffered saline (PBS): 1.5%;

[0054] Sodium benzoate: 0.5%.

[0055] The above formula is mixed and proportioned to obtain the cleaning liquid of the present application.

[0056] Reason for selection: Efficient cleaning: The combination of surfactants and buffers can effectively remove blood residues on the test tip, ensuring the accuracy of the test.

[0057] Biocompatibility: Mild ingredients will not cause chemical damage to the test tip or sample.

[0058] Stability: The addition of preservatives extends the shelf life of the cleaning fluid and reduces the trouble of frequent replacement.

[0059] The absorbent cotton is made of non-woven fabric material made of polypropylene fiber (PP) or polyester fiber (PET).

[0060] Polypropylene fiber (PP): has good water absorption and hydrophilicity, and can quickly absorb blood residue on the test head.

[0061] Polyester fiber (PET): has high mechanical strength and durability and can be used multiple times without being easily damaged.

[0062] Reason for selection: efficient absorption: The high water absorbency of polypropylene fiber ensures that the blood on the test head can be quickly absorbed to avoid dripping contamination.

[0063] Durability: The high strength and durability of polyester fiber ensures that the absorbent cotton can maintain its good performance after repeated use.

[0064] Environmental protection: non-woven fabric materials are biodegradable, reducing environmental pollution and meeting environmental protection requirements.

[0065] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

[0066] On the basis of the above scheme, the equipment structure and control method are further optimized, and a buffer pad is set on the inner wall of the blood sample tube placement seat 8. The buffer pad is made of silicone material, which can effectively reduce the vibration of the blood sample tube during placement and rotation, and protect the sample tube from damage.

[0067] The steps and principle of use are as follows: when in use, the blood sample tubes are inserted into the blood sample tube placement seat 8 one by one. After storage is completed, the locking screw 14 in the nut 13 is screwed in, so that the locking screw 14 locks the blood sample tubes in the blood sample tube placement seat 8;

[0068] Afterwards, the driving motor 11 is started to drive the active gear disc 12 to rotate, and the active gear disc 12 is engaged with the driven gear disc 10 to drive the blood sample tube placement seat 8 on the rotating shaft 9 to rotate, so as to shake the blood in the blood sample test tube. After the shaking, the electric push rod 2 5 is started to push the blood sample tube placement seat 8 on the circular sealing disk 7 upward, so that the circular sealing disk 7 seals the circular sealing hole 15. At the same time, the electric guide rail 16 is started to drive the sealing cover 17 to move, so that it is tightly attached to the detector body 1 and seals the detection window 3, thereby realizing that the circular sealing disk 7, the detector body 1 and the sealing cover 17 are combined into a sealed state.

[0069] In the sealed state, the driving motor 11 is operated to drive the blood sample tubes on the blood sample tube placement seat 8 to rotate one by one. At the same time, the electric guide rail 23 is cooperated to drive the clamping block 27 to move to the outside of the blood sample tube. The electric push rod 3 26 is driven to push the clamping block 27 to clamp the sealing cover of the blood sample tube. The servo motor 24 drives the clamping block 27 to rotate and screw back the sealing cover of the blood sample tube. At the same time, the electric push rod 2 5 is cooperated to drive the blood sample tube downward, thereby realizing the above-mentioned coordinated operation to open the sealing cover of the blood sample tube one by one.

[0070] After the sealing cover is opened, the electric guide rail 23 drives the clamping block 27 to move to the outside of the blood sample tube to avoid obstruction of the rotation detection of the blood sample tube. Afterwards, in the sealed state, the driving motor 11 and the electric push rod 25 work together to realize the rotation of the stored blood sample tubes one by one and move them into the detection head 4 for automatic detection. This improves the detection efficiency and realizes the detection in a closed environment to avoid contamination of the blood sample.

[0071] After each blood sample tube is tested, the electric push rod 19 is used to push the absorbent cotton 22 on the U-shaped seat 20 and insert it into the outside of the test head 4. In conjunction with the upward movement of the test head 4, the absorbent cotton 22 absorbs the blood on the outside of the test head 4 to prevent the test head 4 from dripping and causing contamination when it moves into the detector body 1. After the absorbent cotton 22 absorbs the blood, the electric push rod 19 drives the absorbent cotton 22 to move into the cleaning cylinder 18.

[0072] Afterwards, the cleaning liquid in the cleaning liquid storage seat 30 is extracted by starting the set liquid extraction pump 31, and the extracted cleaning liquid is sprayed out through the nozzle 29 on the drainage hose 32, thereby cleaning the absorbent cotton 22. The sewage after cleaning is discharged into the liquid accumulation seat 36 through the sewage hose 35 for storage. After the absorbent cotton 22 is cleaned, the fan 33 works to spray air through the nozzle 29 on the exhaust hose 34, thereby drying the cleaned absorbent cotton 22, thereby avoiding blood adhering to the outside of the detection head 4 when the detection head 4 is received into the detector body 1, which is easy to drip into the detection window 3 and cause contamination.

[0073] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
