The invention belongs to the technical field of medical instruments, and discloses an auxiliary device for sputum adsorption of the elderly respiratory medicine department. The auxiliary device comprises a sputum suction tube, wherein a through hole is formed in the bottom end of the sputum suction tube, a one-way valve is arranged at the other end of the sputum suction tube, a negative pressure cavity is formed in the left side of the one-way valve, and an L-shaped tube communicates with the left side of the one-way valve. When the sputum suction device is in use, after the sputum suction tube extends into the position, where sputum needs to be sucked, in the respiratory tract of a patient, the sputum suction tube can be effectively prevented from slipping off from the respiratory tract of the patient through an anti-slipping assembly, and then a pull rod and a piston are driven to move rightwards by drawing a handle, so that negative pressure is generated in a negative pressure cavity, then the sputum in the respiratory tract of the patient is sucked into the sputum suction pipe through an L-shaped pipe and then collected into a sputum collecting barrel through a sputum outlet and a connector, and thus sputum suction operation is completed; and the problem that the auxiliary device for sputum adsorption is easy to slip off from the respiratory tract of the patient is solved,and the pain of the patient is relieved.

The invention relates to a biological bamboo fiber mask base cloth with high water preservation performance and an anti-dropping function and a moisture mask with high water preservation performance.A preparation method of the mask base cloth includes the following steps that 1, nanometer bamboo carbon powder is modified by a silane coupling agent to obtain modified bamboo carbon powder; 2, the modified bamboo carbon powder and a dispensing agent are added into a gelatin solution and dispersed uniformly to obtain bamboo slurry; 3, polylactic acid is dissolved in trichloromethane to prepare aspinning solution, the spinning solution is subjected to electrostatic spinning to obtain a polylactic acid fibrofelt, and the polylactic acid fibrofelt is soaked in the bamboo slurry for dipping andmodification to obtain a modified fibrofelt; 4, sodium alginate is added into chitosan liquid for dissolution to obtain a finishing liquid, and the modified fibrofelt is soaked in the finishing liquidfor after-finishing to obtain a compound fibrofelt; 5, hydroentangling and reinforcement are conducted on the compound fibrofelt to obtain a finished product. The obtained biological bamboo fiber mask base cloth has an excellent constraint capability on essence liquid and great liquid preservation and moisture releasing performance. After the essence liquid is loaded on the cloth by liquid suspension, the moisture mask with high water preservation performance is obtained, the situation that loss of the essence liquid is caused since the essence liquid flows down and drops is avoided, and waste is prevented.

A multifunctional sputum scab remover for the pneumology department comprises an annular movable plate, an annular fixed plate is arranged at the right side of the annular movable plate, the annular fixed plate is coaxial with the center line of the annular movable plate, the annular fixed plate and the annular movable plate are fixedly connected through a rubber tube, the same first hose is movably mounted at the inner sides of the annular movable plate and the annular fixed plate, the left side of the annular movable plate is in bearing connection with an inner sleeve sleeving the peripheryof the first house through a sealing bearing, an outer sleeve is arranged surrounding the inner sleeve, and the right side of the outer sleeve is in bearing connection with the left side of the annular movable plate through a sealing bearing. The multifunctional sputum scab remover has the advantages of simple structure, ingenious conception, rapidness and effectiveness in sputum and sputum scab in a trachea cannula by using an imbibition scraper plate, cleaning time shortening, simultaneous realization of cleaning and discharging of the cleaned sputum and sputum scab, one-shot completion of cleaning, avoiding of secondary insertion of the trachea cannula to a cleaning device, and reduction of pains of patients.

An anti-smog screen window, at least a part of which includes at least one layer of gauze; when there are multiple layers of gauze, each gauze is interlaced with each other, and there is a gap between each gauze, and there is also a protective net to prevent users from touching the gauze; the gauze The fiber thread includes a coating capable of generating static electricity through friction with flowing air, said fiber thread is made of polyethylene terephthalate, and the coating is made of terpolymer elastic rubber; the gauze Pollution particle detectors are installed on the inner and outer sides respectively. The upper edge of the gauze is equipped with a water waterfall uniform flushing tank, and the lower edge is equipped with a sewage collection tank. The joints that are sealed and connected, the water injection container and the water collection container are a container. The container is unloaded after the water waterfall flushing tank is filled with water, and then installed on the sewage collection tank to collect sewage. After the sewage is collected, the container is emptied , rinse off and reuse. The window screen of the invention can realize automatic cleaning.
