Problems solved by technology
[0002] In the Department of Respiratory Medicine, most patients in the Department of Respiratory Medicine have symptoms of excessive sputum. If the sputum is not sucked out in time, airway blockage, hypoxia, and dyspnea are prone to occur, threatening the life of the patient. The sputum aspirator is Common instruments in respiratory medicine, the principle of the sputum aspirator is mainly to suck out the sputum in the human body through negative pressure suction. At present, most of the sputum aspirators in the respiratory medicine are electric, and they need to use a power supply when using them. The requirements for the use environment are relatively strict, and it is very inconvenient when it needs to be carried
[0003] The publication number is CN108771773B, which provides an easy-to-clean manual sputum aspirator, which sucks sputum by manually generating negative pressure, which greatly reduces the volume of the sputum aspirator, but especially the handle frame is longer and occupies a relatively large volume , all take up space when carrying and placing, and the portability is relatively poor; and the negative pressure of the above-mentioned sputum suction device is driven by the connecting rod to drive the rubber piston plate to extract gas to generate negative pressure, and the air pressure change during extraction cannot be adjusted. For weaker patients, the negative pressure generated is likely to be too large, which is likely to cause damage to the human oral cavity and respiratory mucosa. Moreover, the above-mentioned sputum suction device mainly generates negative pressure in the connecting tube, and the sucked sputum is discharged to the sputum collection through the connecting tube. In the pipe, since the connecting pipe and the suction pipe are connected, the suction pipe is not easy to enter the interior of the suction pipe, and it is easy to contaminate the internal rubber piston plate, connecting rod, compression spring and other devices, causing hygienic problems, which is not conducive to the later stage. cleaning and maintenance

The invention provides a portable manual sputum aspirator. The portable manual sputum aspirator comprises a barrel, an adjusting assembly, a suction tube, a sealing cover, a liquid storage tank, a sputum aspiration tube, a supporting plate, a piston, a lifting rod, a reset spring, a guide assembly, a handle, a supporting assembly and an exhaust one-way valve. According to the portable manual sputum aspirator, the position and angle of the handle can be adjusted freely by virtue of the connecting mode of the handle and the supporting assembly; when the manual sputum aspirator is not used, the handle can be folded to the side of the barrel, so that the space occupied by storage and carrying is greatly reduced, and the portability of the manual sputum aspirator is improved; the volume of airextracted every time the piston moves can be freely adjusted by changing the size of the air inlet section in the adjusting assembly and the position of the piston before air extraction, so that the suction force during sputum aspiration is changed, the requirements of various different patients are met, the situation that the body of a patient is damaged due to large suction force can be effectively prevented, and sanitation of the sputum aspirator during use can be guaranteed; and the sealing cover and the sputum aspiration tube can be detached and are easy to clean and disinfect.
