As shown in fig. 5, the suction tube 2 further includes a third working channel 23, and a liquid supply module 10 electrically connected to the control module 100 is provided in the third working channel 23.
The third working channel 23 is used for diluting sputum, and the control module 100 controls the liquid supply module 10 so as to control the opening and closing, flow rate, etc. of the liquid supply module 10. When the sputum of a patient is sticky, the airway is required to be flushed so as to dilute the sputum, so that the sputum is conveniently sucked out, and sputum scab is prevented from forming. When the sputum is viscous, the negative pressure cannot be simply increased, and the excessive negative pressure of sputum suction or damage to the trachea or the non-stretching of alveoli can be caused, so that the sputum can be flushed through the third working channel 23. The liquid supplied into the third working channel 23 by the liquid supply module 10 is normal saline or 2% sodium bicarbonate solution.
The control module 100 is further configured to obtain current viscosity information via the viscosity sensor 8, and control the liquid supply flow rate and/or the liquid supply time of the liquid supply module 10 according to the viscosity information. For example, when the liquid supply amount reaches 5mL or the liquid supply time reaches 30s, the control module 100 stops the liquid supply.
The viscosity sensor 8 transmits the detected viscosity information of the human body cavity to the control module 100, and the control module 100 automatically adjusts the flow rate of the washing water, thereby improving the sputum suction efficiency.

The image acquisition module 4, the shielding prevention module 6 and the viscosity sensor 8 are accommodated in the head end module. The head end module cover 7 is provided with a first through hole (not shown) communicated with the second working channel 22 and a second through hole (not shown) communicated with the third working channel 23.
In addition, the top of the head end module cover 7 is provided with an anti-adhesion coating 70, and sputum adhesion can be effectively reduced by arranging the anti-adhesion coating 70, so that the head end module can collect images conveniently. The anti-blocking coating 70 may be implemented as a highly hydrophobic organic coating, such as a fluorine-containing coating or a silicon-containing coating, wherein the surface of the fluorine-containing groups in the fluorine-containing coating is capable of decreasing in surface function with increasing number of fluorine atoms substitution, and thus the hydrophobic function of the coating increases with increasing number of fluorine atoms. For silicon-containing coatings, special structures are built on the surface of the coating mainly by a sol-gel method, and meanwhile, low-surface energy substances containing silane monomers with certain long carbon chains can be introduced to increase the hydrophobicity. The coating is coated on the top end of the head end module, so that the image blurring phenomenon caused by the adhesion of sputum can be effectively reduced.
As shown in fig. 6, the control module 100 further includes a temperature sensor 1000, a humidity sensor 1001, and a reuse prevention module 1002 communicatively connected to the respective elements of the circuit. The display device 3 may also display the determination result of the reuse prevention module 1002. The humidity sensor 1001 may be realized as a thin film humidity sensor, which uses a capacitor with a high molecular polymer as a medium, and changes a capacitance value due to absorption (or release) of water vapor, and has a small volume and high measurement accuracy.
The suction tube 2 is usually stored in an environment of a fixed temperature and humidity, for example, an environment of 25 degrees and 50% humidity, when not in use. When the temperature parameter of the environment in which the suction tube 2 is located is greater than 36 degrees and the humidity parameter is greater than 50% by the temperature sensor 1000 and the humidity sensor 1001 due to the difference in temperature and humidity in the human body, the suction tube 2 may be used, and the "used" determination information is generated in the reuse prevention module 1002 according to the determination of the temperature sensor 1000 and the humidity sensor 1001, and the determination information is output and displayed by the display device 3. Therefore, the suction tube 2 can be prevented from being used secondarily, the possibility of cross infection is avoided, and the safety and the sanitation of medical appliances are improved.
As shown in fig. 7, the side wall of the second working channel 22 is provided with one or more side suction holes 221 therethrough. The side suction hole 221 is provided near the sputum suction port. The side wall of the second working channel 22 is provided with one or more side suction holes 221, which can help to suck sputum smoothly and prevent adhesion to the cavity wall during the suction process.
In addition, the side suction holes 221 may be clamped to human tissue during sputum suction, and therefore, anti-suction clamping balls may be disposed at the side suction holes 221 in the second working channel 22, and the side suction holes 221 and the anti-suction clamping balls are disposed in one-to-one correspondence, so that discomfort caused by the suction of human tissue by the side suction holes 221 can be effectively avoided.
Further, the control module 100 of the operating handle 1 is used to control the operating state of the suction module 101 according to a preset operating threshold.
For example, the control module 100 may control the operating time of the aspiration tube 2 to prevent hypoxia in the patient caused by excessive aspiration of sputum. Preferably, the operating time of the suction tube 2 is controlled to 15 seconds, and the sputum suction is automatically stopped when the suction tube 2 performs a suction operation for 15 seconds.
While the invention has been described with reference to several exemplary embodiments, it is to be understood that the terminology used is intended to be in the nature of words of description and of limitation. As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalences of such meets and bounds are therefore intended to be embraced by the appended claims.
