When switching to the blood drawing process, the blood storage chamber 8 can be freely drawn out, and the height of the moving drive gear 926 is greater than the lifting height of the electric lifting cylinder 9, so that the sliding gear plate 82 and the moving drive gear 926 can always be engaged during the lifting process.

[0069] Through the linkage drive structure, the blood collection and disinfection work are not affected by each other, so as to ensure the purity of the collected blood and the continuity of the work. The electric lifting cylinder 9 drives the lifting plate 91 to lift and lower, and the lifting plate 91 drives the three-way valve 61 and the lifting plate 91 connected to it and the transmission gear box 92 and the transmission gear group 921 connected to it to lift and lower during the movement, and the valve driving gear 622 is driven to rotate by the fixed gear plate 16 during the lifting and lowering movement of the lifting connecting plate 6, and the valve driving gear 622 drives the three-way ball valve core 62 to rotate through the valve shaft 621 during the rotation, thereby realizing the switching of the passage, and then completing the switching of blood drawing and cleaning work, and the lifting connecting plate 6 completes the connection or separation of the blood test tube 81 and the three-way valve 61 during the lifting process.

[0070] The workflow of the technical solution provided by the present invention is as follows:

[0071] First, the user puts on a compression cuff in advance to make the arm meridians protrude, which is convenient for subsequent identification and positioning, and then extends the arm into the collection hole 12. After the blood drawer extends the arm into the collection hole 12, the arm is placed on the arm pad 121, and a restraint belt 122 can be tied to prevent the user's arm from shifting when drawing blood. At the same time, the disinfection patch device 23 sprays and disinfects the blood drawing position.

[0072] The vein position of the arm is found by the recognition camera assembly 32, and the two-axis moving structure composed of the moving slide 31 and the moving connecting top plate 41 controls the precise moving action through the recognition result, and the collection connection block 33 drives the collection needle assembly 34 to perform puncture and blood collection, and the blood pump motor 52 drives the peristaltic blood pump 5 to perform pumping action. The blood collected by the collection assembly 3 is sent into the three-way valve 61 through the blood drawing hose 331, and is sent to the plug-in connecting tube 811 through the snap sleeve 612, and then flows from the plug-in connecting tube 811 to the blood test tube 81 for collection. After the collection is completed, the process is switched by the electric lifting cylinder 9, and the plug-in connecting tube 811 and the three-way valve 61 are separated during the switching process, and the plug-in connecting tube 811 is sealed by external pressure and heat through the heat sealing machine.

[0073] The electric lifting cylinder 9 drives the lifting plate 91 to perform lifting and lowering movements, and during the movement of the lifting plate 91, the three-way valve 61 and the lifting plate 91 connected thereto, as well as the transmission gear box 92 and the transmission gear set 921 connected thereto, are driven to lift and lower together, and during the lifting and lowering movement of the lifting connecting plate 6, the valve driving gear 622 is driven to rotate by the fixed gear plate 16, and during the rotation, the valve driving gear 622 drives the three-way ball valve core 62 to rotate through the valve shaft 621, thereby realizing the switching of the passage, and then completing the switching of blood drawing and cleaning.

[0074] The peristaltic blood pump 5 is then driven by the blood pump motor 52 to reverse. At this time, the disinfectant inside the cleaning and disinfection box 7 is sent into the blood drawing hose 331 through the flushing hose 611 and the three-way valve 61, and is sent into the collection needle tube assembly 34 and the collection connecting block 33 through the blood drawing hose 331 for disinfection treatment. The waste liquid discharged by the collection needle tube assembly 34 is discharged into the waste liquid tank 22, and the collection needle tube assembly 34 is disinfected by the disinfection patch device 23.

[0075] At the same time, the blood pump motor 52 drives the switching drive gear 522 to rotate through the reduction gear 521, and the switching drive gear 522 drives the transmission gear set 921 and the transmission bevel gear 923 connected thereto to rotate during the rotation, and the transmission bevel gear 923 drives the driven bevel gear 925 to rotate during the rotation, and the driven bevel gear 925 drives the moving drive gear 926 to rotate during the rotation. The moving drive gear 926 drives the sliding gear plate 82 and the blood storage chamber 8 connected thereto to move during the rotation, and when the equipment completes a cleaning operation, the blood test tube 81 in the blood storage chamber 8 completes a position movement switch, and at this time can be driven by the electric lifting cylinder 9 to perform a falling action, completing the switching of the blood test tube 81 and the switching of the next blood drawing process, that is, when it moves to the next test tube position, the empty blood test tube 81 is connected to the snap sleeve 612 again through the lifting action, and the next blood drawing process can be carried out at this time.

[0076] During the blood drawing process, the attention of the blood drawer can be diverted by playing a decompression video or an advertising video on the display screen 11, and the doctor, nurse or accompanying person can observe the blood drawing work from the side through the observation window 13 to prevent accidents. When the blood storage chamber 8 moves to the maximum distance, the machine will sound an alarm to remind the staff to replace the blood test tube 81. The blood storage chamber 8 can be drawn out or put in by manually opening and closing the blood chamber door 15, and when internal maintenance is required, the main body 1 of the collector can be opened through the removable back panel 14.

[0077] The present invention encompasses any alternatives, modifications, equivalents, and solutions that fall within the spirit and scope of the present invention. While specific details are described in detail in the preferred embodiments to provide a thorough understanding of the present invention, those skilled in the art will be able to fully understand the present invention without these details. Furthermore, to avoid unnecessary confusion regarding the essence of the present invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0078] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
