The metal mesh is arranged between the shielding cable 62 and the signal transmission cable 9, and the signal shielding rings are arranged at the two ends of the shielding cable 62 to reduce the electric signal interference between the shielding cable 62 and the signal transmission cable 9, so that the phenomenon that signals are shielded due to human organs after the head end module enters a human body can be prevented, the signals which are transmitted in a set mode are amplified through the operational amplifier 61, and the stability of signal transmission is ensured.
As shown in fig. 5, the suction tube 2 further includes a third working channel 23, and the liquid supply module 10 electrically connected to the control module 100 is disposed 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, the flow rate, and the like of the liquid supply module 10. When patient's sputum is sticky, need carry out the air flue and wash to dilute the sputum, the sputum suction of being convenient for prevents to form the sputum scab. The sputum cannot be simply increased in negative pressure when being viscous, and the sputum suction negative pressure is too large or causes tracheal injury or alveolar atelectasis, so the sputum can be washed through the third working channel 23. The liquid supplied by the liquid supply module 10 into the third working channel 23 is normal saline or 2% sodium bicarbonate solution.
The control module 100 is further configured to obtain current viscosity information through 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 inner cavity of the human body to the control module 100, and the control module 100 automatically adjusts the washing water flow, so that the sputum suction efficiency can be improved.
As shown in fig. 4 and 5, the surface of the head end module is covered with a head end module cover 7, and the head end module cover 7 may be implemented as a transparent plastic cover. The image acquisition module 4, the anti-shielding 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 head end module lid 7 is provided with antiseized glutinous coating 70, through setting up antiseized glutinous coating 70, can effectively alleviate the sputum adhesion to the head end module carries out image acquisition. The anti-adhesive coating 70 may be implemented as a highly hydrophobic organic coating, such as a fluorine-containing coating or a silicon-containing coating, in which the surface of the fluorine-containing group in the fluorine-containing coating can be decreased in surface function as the substitution number of fluorine atoms increases, and thus the hydrophobic function of the coating increases as the number of fluorine atoms increases. For the silicon-containing coating, a special structure is constructed on the surface of the coating mainly by a sol-gel method, and meanwhile, a low-surface-energy substance containing a silane monomer with a fixed length of carbon chain can be introduced to increase the hydrophobicity. The image blurring phenomenon caused by the adhesion of sputum can be effectively relieved by coating the coating on the top end of the head end module.
As shown in fig. 6, the control module 100 further includes a temperature sensor 1000 and a humidity sensor 1001, and a reuse prevention module 1002 communicatively connected to the respective components 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 implemented as a thin film humidity sensitive capacitor, which uses a high molecular polymer as a dielectric capacitor, and changes a capacitance value due to absorption (or release) of water vapor, and has a small volume and high measurement accuracy.
When not in use, the suction tube 2 is usually stored in an environment of a fixed temperature and humidity, for example, an environment of 25 degrees in temperature and 50% in humidity. When the temperature sensor 1000 and the humidity sensor 1001 acquire that 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%, due to the difference between the temperature and the humidity in the human body, and the suction tube 2 is likely to be used, determination information of "used" 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. This prevents the suction tube 2 from being used again, thereby avoiding the possibility of cross infection and contributing to the improvement of the safety and hygiene of the medical instrument.
As shown in fig. 7, one or more side suction holes 221 are formed through the sidewall of the second working channel 22. The side suction hole 221 is disposed near the sputum suction port. One or more side suction holes 221 are formed in the side wall of the second working channel 22 to facilitate smooth sputum suction and prevent adhesion to the cavity wall during suction.
In addition, the side suction holes 221 may clamp human tissues during sputum suction, for this reason, anti-suction clipping 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 clipping balls are disposed in one-to-one correspondence, so that discomfort caused by the suction of human tissues by the side suction holes 221 may be effectively avoided.
Furthermore, 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 can control the working time of the suction tube 2 to prevent the patient from being lack of oxygen due to excessive sputum suction. Preferably, the working time of the suction tube 2 is controlled to be 15 seconds, and when the suction tube 2 performs suction operation for 15 seconds, sputum suction is automatically stopped.
While the present invention has been described with reference to several exemplary embodiments, it is understood that the terminology used is intended to be in the nature of words of description and illustration, rather than 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.
