Description
Technical Field
The invention belongs to the field of medical auxiliary tools, and particularly relates to an intelligent suction device for preventing tube drawing from splashing and a use method thereof.
Background
When the traditional tracheal catheter is used for extubation and sputum aspiration through the tracheal catheter, a large amount of secretion, blood or spray or aerosol can be splashed due to the stimulation of the airway, and particularly, the tracheal catheter is used for extubation or sputum aspiration of a patient suffering from diseases transmitted through the respiratory tract, such as a novel coronavirus pneumonia patient, and the tracheal catheter is in high-risk operation in medicine due to the fact that an operator is very close to the head and the face of the patient. When the tracheal catheter is pulled out, the tracheal catheter and the respiratory circuit are disconnected, then the tracheal catheter is placed into the sputum suction tube to perform the sputum suction operation in the catheter, and the sputum suction can often cause choking and cough of a patient, so that respiratory tract spray and aerosol are generated or secretion is sprayed outwards through the tracheal catheter, and cross infection of medical workers and other patients is easily caused.
Disclosure of Invention
In order to solve the technical problems, the invention provides the intelligent suction device for preventing the spray of the tube drawing and the use method thereof, wherein the piezoelectric film sensor in the tracheal catheter senses the pressure change of the airway at the spray moment, the pressure is judged whether to exceed a set warning value by the value of the singlechip corresponding to the analog-to-digital conversion of an electric signal after signal conversion and amplification, and the suction device is started when the pressure exceeds the set warning value, so that the intelligent suction method for preventing the spray of the tube drawing is realized, the risk that medical staff is infected by the spray of the spray, aerosol or secretion of a patient during the tube drawing operation is reduced, and the medical staff is better protected.
The technical scheme of the invention is as follows: the intelligent suction device comprises a piezoelectric film sensor, a breathing filter, an instrument amplifier, a singlechip, a relay and a suction device, wherein the breathing filter comprises filter cotton and a far-end interface, and the piezoelectric film sensor is arranged between the filter cotton and the far-end interface; the filter cotton is arranged in the breathing filter;
the piezoelectric film sensor is connected with the piezoelectric film sensor connector on the filter layer lower cover through the piezoelectric film sensor plug and then connected to a lead, and the breathing filter extends out to be connected with an instrument amplifier;
the instrument amplifier is connected with the singlechip through a wire, the singlechip is connected with the relay through a wire, and the relay is connected with the aspirator through a wire; the respiratory filter is connected with the aspirator through a proximal end interface of the gas pipeline.
Further, the piezoelectric thin film sensor includes: piezoelectric film, plug of piezoelectric film sensor, ring-shaped bracket and supporting leg; the piezoelectric film is adhered below the annular bracket.
Furthermore, the piezoelectric film sensor is connected with the piezoelectric film sensor connector on the lower cover of the filter layer through a piezoelectric film sensor plug, and the piezoelectric film sensor plug and the piezoelectric film sensor connector are connected in a plug-connector mode.
Further, a plurality of supporting feet are connected around the annular support, the supporting feet are in a flake shape, and the height of the supporting feet is larger than the thickness of the annular support.
Furthermore, the piezoelectric film is made of polyvinylidene fluoride film or coarse fiber piezoelectric composite film.
Further, the piezoelectric film is strip-shaped or circular.
According to another aspect of the present invention, a method for using an intelligent suction device for preventing splashing in a tube drawing is provided, comprising the steps of:
the remote end interface of the breathing filter of the tube drawing splash-proof intelligent suction device is connected with the tracheal catheter, the suction device is connected with the near end interface of the breathing filter, when a patient chokes to generate instantaneous pressure increase in an air passage, the pressure change is sensed and converted into an electric signal by the piezoelectric film sensor, the signal is amplified and transmitted to the singlechip through the instrument amplifier, the singlechip is programmed to set a preset pressure warning value, when the pressure exceeds the warning value, the suction device is started through the relay, and the suction device sucks gas/spray from the breathing filter through the near end interface gas pipeline of the breathing filter, so that the intelligent splash suction is realized, and meanwhile, the pressure change is connected with the buzzer or the LED lamp through the I/O interface of the singlechip to flash and alarm to medical staff.
Compared with the prior art, the invention has the following differences and advantages:
(1) The prior clinical practice mainly adopts that the tracheal catheter is directly connected into the respiratory circuit, the tracheal catheter and the respiratory circuit are disconnected before the tracheal catheter is pulled out, and then the tracheal catheter is placed into the sputum suction tube to perform the sputum suction operation in the catheter, and then the tracheal catheter is pulled out. The disadvantage of the above method is that during sputum aspiration, the patient is prone to choking and at this point a large amount of spray, aerosol is instantaneously sprayed onto the end of the catheter, potentially risking infection by the spray, aerosol or secretions.
(2) The innovation of the invention is that: the invention applies the piezoelectric film sensor and automatic suction to the tracheal catheter tube drawing link, and serves clinical scenes. The airway pressure caused by patient choking cough before tube drawing is increased instantaneously, the pressure change is converted into electric signal by the pressure sensor, the electric signal is amplified and transmitted to the singlechip, a certain pressure warning value is set by combining the singlechip program, and the aspirator is started automatically when the pressure exceeds the warning value, so that the splashed spray is sucked intelligently, and meanwhile, the buzzer or the LED lamp is connected through the I/O port of the singlechip to flash and alarm to medical staff.
1) The piezoelectric film sensor is of a passive structure, and does not need a power supply, so that the system has small power consumption and a simple structure;
2) The signal of the piezoelectric film sensor is only related to the vibration generated by the gas, so that the anti-interference capability is strong, and the application range is wide;
3) The piezoelectric film sensor has low cost, can be manufactured into a disposable adhesive sensor, and is discarded after being used once or a plurality of times;
4) The piezoelectric film sensor leads out the electric signal through the plug-connector and the external guide wire.
The method can completely attract and recycle the spray or aerosol sprayed by the patient due to choking and cough when the tube is drawn, and reduces the risk of infection of the spray, aerosol or secretion sprayed by the patient when the medical staff operates.
