DETAILED DESCRIPTION OF THE EMBODIMENTS

The present invention is further illustrated below in combination with the drawings.

As shown in FIG. 1, an embodiment of the present invention is a device for removing sputum scabs of a respiratory tract, comprising an outer housing 1. The front end of the outer housing 1 is provided with a removing part 2; the removing part 2 can come into contact with the lower respiratory tract of a human body; meanwhile, a fluid hole 3 is designed on the front end of the removing part 2; the fluid hole 3 can be used for spraying fluid of gas and liquid; and under the action of a power pump, the fluid can be sprayed out from the fluid hole 3 at certain pressure. Based on the above purpose, the fluid hole 3 needs to be communicated with an air flow pipe 4 and a liquid flow pipe 5 respectively through pipelines; accordingly, the air flow pipe 4 and the liquid flow pipe 5 need to extend to the outside of the outer housing 1; the liquid flow pipe 5 is communicated with a liquid pump 6; and the air flow pipe 4 is communicated with an air pump 7. More importantly, the outer edge of the removing part 2 needs to be provided with a plurality of negative pressure holes 8; and the negative pressure holes 8 are communicated with a negative pressure cavity 9 through a negative pressure pipeline (not shown in the figures) inside the outer housing 1. Herein, in order to save the space in the outer housing 1, the negative pressure pipeline can be designed outside the air flow pipe 4 and the liquid flow pipe 5. Moreover, the above negative pressure pipeline also needs to be communicated with a sputum collecting tank; and a check valve needs to be installed between the sputum collecting tank and the negative pressure pipeline to ensure that after entering the sputum collecting tank, the sputa are not sucked out by negative pressure in the negative pressure pipeline. Meanwhile, to facilitate the contact between the removing part 2 and the inner wall of the lower respiratory tract of the human body, the outer edge and the front end of the removing part 2 can be designed as circular arcs to reduce the irritation and discomfort to the inner wall of the respiratory tract of the human body caused by the removing part 2.

Herein, preferably, based on the device of the above structure, the fluid hole 3 is directly communicated with the external air pump 7 through the pipeline and the air flow pipe 4; and the fluid hole 3 is communicated with the external liquid pump 6 through the pipeline and the liquid flow pipe 5. Thus, under the action of the liquid pump 6 and the air pump 7, liquid and gas can be alternately sprayed out through the fluid hole 3, and the output pressure of the liquid pump 6 and the air pump 7 is adjusted according to required pressure. Meanwhile, as shown in FIG. 1, in the shape design of the device, the outer housing 1 can be designed as a circular tubular body, and the removing part 2 can be designed as a conical tubular body.

In the present embodiment, the fluid hole 3 is designed on the removing part 2 at the front end of the outer housing 1, and the fluid hole 3 is respectively communicated with the liquid pump 6 and the air pump 7, so that the device can be extended into the lower respiratory tract of the patient during use. Then, the sputum scabs attached to the inner wall of the respiratory tract can be softened and removed by alternately spraying the liquid and the gas through the fluid hole, and the removed sputum scabs can be sucked out through the negative pressure holes, so as to prevent the scabs of the secretions of the lower respiratory tract from blocking the tracheae, so that the pain of the patient is reduced during implementation of the tracheal intubation.

According to another embodiment of the present invention, as shown in FIG. 2, for the convenience of sucking the secretions of the sputa on the lower respiratory tract, the plurality of the negative pressure holes S are designed to be distributed in a cross array on the outer edge of the removing part 2. In the present embodiment, preferably, to further reduce the irritation to the inner wall of the lower respiratory tract by the removing part 2 and avoid cross infection during the use of the device, as shown in FIG. 3, the outer edge of the removing part 2 is sleeved with an annular friction sleeve 10; and the annular friction sleeve 10 is disposable and can be processed by soft silica gel. Meanwhile, to avoid influencing the negative pressure, openings corresponding to the negative pressure holes 8 shall be added on the annular friction sleeve 10 to ensure that the negative pressure holes 8 can be exposed and the secretions on the inner wall of the lower respiratory tract can be normally sucked out.

Based on the above structure, during the test, the inventor also finds that the light of the lower respiratory tract of the human body is insufficient, and the operation of removing the sputum scabs is not accurate enough. Therefore, the device in the above embodiment is further improved. As shown in FIG. 4, the inventor firstly thinks of directly installing an illuminating lamp 12 on the front end of the removing part 2, connecting the illuminating lamp 12 to a power supply and then installing the power supply in the outer housing 1. Thus, during use, the illuminating lamp 12 is lit to illuminate the inner wall of the lower respiratory tract of the human body, which is conducive to improving the operation accuracy of doctors when the sputum scabs are removed. On this basis, the inventor also learns from the imaging technology of a miniature camera. As shown in FIG. 5, a miniature camera 11 is installed on the front end of the removing part 2; a lamp of the camera 11 is connected to a control module; the control module is installed in the outer housing 1; and the control module is also connected to the power supply. Thus, a real-time image of the inner wall of the lower respiratory tract of the human body can be collected through the camera 11, and the real-time image is projected onto an external display screen through the control module, to assist the doctors to remove the sputum scabs on the lower respiratory tract of the patient more accurately. The operation is more convenient, and conducive to increasing the efficiency of removing the sputum scabs. Because the miniature camera and the image transmission technology have been maturely used in the existing medical equipment, the specific imaging principle of the image is not detailed herein.

As shown in FIG. 1 to FIG. 5, in actual use of a preferred embodiment of the present invention, when the sputum scabs on the lower respiratory tract of the patient need to be removed for the tracheal intubation or other clinical treatment operations, an annular friction sleeve 10 made of silica gel is sleeved on the removing part 2. The external liquid pump 6 is started at first; the pressure is adjusted and then distilled water is sprayed out from the fluid hole 3 through the liquid flow pipe 5 by the liquid pump 6 and acts on the sputum scabs of the inner wall of the respiratory tract to soften the sputum scabs. Then, the external air pump 7 is started; the pressure is adjusted and then air is sprayed out from the fluid hole 3 through the air flow pipe 4 by the air pump 7. The softened sputum scabs are washed down through the air flow. Meanwhile, the negative pressure cavity 9 forms negative pressure in the negative pressure pipeline, so that the washed sputum scabs are immediately sucked into the negative pressure holes 8 and finally enter the sputum collecting tank. In the above process, the illuminating lamp 12 and the camera 11 at the front end of the removing part 2 can also be used to assist in finding the positions of the sputum scabs on the inner wall of the lower respiratory tract of the patient more accurately to ensure the removing efficiency, facilitate the successful implementation of the tracheal intubation and other related clinical treatment operations and reduce the pain of the patient.
