[0034] like Figure 1 to Figure 8 As shown, the bypass sputum concentration detection components 6 are provided with no less than two groups.

[0035] like Figure 1 to Figure 8As shown, a multi-groove probe head 201 is fixedly provided at one end of the probe hose 2 away from the lower reversing valve 4 .

[0036] When in use, the multi-slot probe head 201 and the probe hose 2 are placed in the patient's airway, and the negative pressure pump 1 generates suction negative pressure, which acts on the patient's airway through the upper reversing valve 3, the main container 501, the lower reversing valve 4, the probe hose 2 and the multi-slot probe head 201, extracts sputum in the patient's airway, and concentrates the sputum in the main container 501. The main filter membrane 502 in the main container 501 can prevent the sputum from dirtying the negative pressure pump 1.

[0037] During the process of extracting sputum from the patient, the doctor can switch the upper reversing valve 3 and the lower reversing valve 4 so that the suction force generated by the negative pressure pump 1 can reach the lower reversing valve 4 through the bypass sputum concentration detection component 6, thereby being able to evaluate whether the sputum in the patient's airway has been basically discharged while extracting the patient's sputum.

[0038] The working principle of the bypass sputum concentration detection component 6 is:

[0039] Sputum enters the transfer container 602 through the pipeline under the action of negative pressure suction. Under normal conditions, the torsion shaft 603 in the transfer container 602 keeps the flip filter membrane 604 in a vertical state and blocks the pipeline entrance between the transfer container 602 and the upper reversing valve 3. As a result, the sputum will stay in the transfer container 602 and gradually drip and gather on the gathering membrane 701.

[0040] Under normal conditions, the tightening electric push rod 703 is in an extended state, and the tightening rope 705 is forced to be in a straight state through the tightening connecting rod 704. The middle part of the gathering membrane 701 is tightened by the tightening rope 705 and the rope buckle 706, and the inner walls of the middle part of the gathering membrane 701 are pressed against each other and prevent the sputum from falling. After the suction force generated by the negative pressure pump 1 flows through the pipeline in the bypass sputum concentration detection component 6 for a certain period of time, the doctor switches the upper reversing valve 3 and the lower reversing valve 4 again, so that the negative pressure suction force still passes through the main container 501. At this time, the sputum in the transfer container 602 still stays on the gathering membrane 701. The doctor controls the two electromagnet positioning pieces 605 to be electrically attracted to each other, causing the torsion shaft 603 to rotate and the flip filter membrane 604 to be placed flat on the gathering membrane 701. The tightening electric push rod 703 contracts, and the tightening rope 705 and the rope buckle 706 are gradually loosened through the tightening connecting rod 704. The gathering membrane 701 is gradually opened under the elastic force of the spring sheet 702, and causes the sputum to gradually fall in the conical transparent tube 606 (the greater the viscosity of the sputum, the slower it falls along the conical transparent tube 606).

[0041] After tightening the electric push rod 703 to perform the contraction action, after waiting for a preset number of seconds for the sputum to fall along the inner wall of the conical transparent tube 606, the linear motor 707 starts to run at a uniform speed, and the detection frame 708 is driven to move up by the lowest stroke position of the linear motor 707. The small light source 709 and the light intensity sensor 710 in the detection frame 708 are respectively arranged on both sides of the conical transparent tube 606, and the light intensity sensor 710 can receive the light from the small light source 709. In the initial process of the detection frame 708 rising, the light emitted by the small light source 709 is irradiated onto the light intensity sensor 710 through the conical transparent tube 606, and the light intensity received by the light intensity sensor 710 remains substantially unchanged. When the detection frame 708 continues to rise to the same height as the sputum in the conical transparent tube 606, the light intensity received by the light intensity sensor 710 is significantly reduced due to the light shielding effect of the sputum. The doctor receives the indication change information of the light intensity sensor 710, and judges the falling distance of the sputum in the conical transparent tube 606 by the running time of the linear motor 707, and further judges the concentration of the sputum. The doctor judges whether the sputum in the patient's airway has been basically discharged according to the sputum concentration, and decides whether to end the patient's airway clearing operation.

[0042] The principle by which doctors judge whether the sputum in the patient's airway has been basically cleared is based on the concentration of sputum:

[0043] The cells in the airway secrete mucus, which wraps pathogenic microorganisms, inflammatory cells and dust, and moves toward the human oral cavity under the mechanical activity of the epithelial cilia in the airway. The above is the natural discharge process of sputum. In the process of the sputum mass naturally moving toward the human oral cavity, the cells in the airway continue to secrete mucus and mix with the sputum mass, so the longer the sputum mass is formed, the greater the viscosity. In the process of clinical airway cleaning, the sputum mass that is formed early and has high viscosity is always drawn out of the airway first, while the sputum mass that is formed late and has low viscosity is drawn out later. Therefore, the doctor can judge the concentration of sputum according to the running time of the linear motor 707 when the illumination sensor 710 changes, and whether the sputum in the patient's airway has been basically discharged and the operation needs to be ended.

[0044] After the linear motor 707, the small light source 709 and the light intensity sensor 710 have completed a detection of the sputum concentration, the flushing pump 607 draws clean water from the outside and cleans the flip-cover filter membrane 604 and the conical transparent tube 606 below to maintain the good reusability of the bypass sputum concentration detection component 6.

[0045] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
