Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0026] like Figure 1-4 As shown, the present embodiment provides an airway care device for post-total laryngeal surgery, which includes a guide tube 2, wherein the guide tube 2 includes an inner tube 201 and an outer tube 202 which are coaxially arranged and not connected to each other, wherein one end of the inner tube 201 is connected to the sputum suction nozzle 1, and the other end is connected to the first connection part 31 of the three-way tube 3, the second connection part 32 of the three-way tube 3 is connected to the sputum collection bottle 5, the third connection part 33 of the three-way tube 3 is connected to the negative pressure device 41, and the third connection part 33 is provided with a filter device 7, and the negative pressure device An airway humidification liquid containing device 42 and two built-in springs 412 are provided in 41. The negative pressure device 41 and the airway humidification liquid containing device 42 are not communicated with each other. One end of the outer side of the airway humidification liquid containing device 42 is connected to one end of the inner wall of the negative pressure device 41 by a built-in spring 412, and the other end of the outer side of the airway humidification liquid containing device 42 is connected to the other end of the inner wall of the negative pressure device 41 by another built-in spring 412. An exhaust hole 413 is provided at the bottom of the negative pressure device 41, and the exhaust hole 413 is connected to the third connecting part 33.

[0027] An outer catheter outflow hole 203 and an outer catheter inflow hole 204 are respectively provided at both ends of the outer catheter 202. An airway humidifying liquid injection hole 421 is provided at the top of the airway humidifying liquid containing device 42, and an airway humidifying liquid discharge hole 422 is provided at the bottom. The airway humidifying liquid injection hole 421 extends out of the top of the negative pressure device 41, and the contact between the airway humidifying liquid injection hole 421 and the negative pressure device 41 is sealed. The airway humidifying liquid discharge hole 422 extends out of the bottom of the negative pressure device, and the contact between the airway humidifying liquid discharge hole 422 and the negative pressure device 41 is sealed. The airway humidifying liquid discharge hole 422 is connected to one end of a first connecting pipe 424, and the other end of the first connecting pipe 424 is connected to the outer catheter inflow hole 204. A valve 423 is provided on the first connecting pipe 424. A connecting rod 6 is connected between the negative pressure device 41 and the sputum collecting bottle 5.

[0028] Among them, Figure 1-3 As shown, the sputum suction nozzle comprises an integrally connected sputum suction nozzle head 101, a sputum suction nozzle body 102 and a sputum suction nozzle tail 103, the sputum suction nozzle head 101 is hemispherical, and a plurality of absorption holes 105 of varying sizes are arranged on the hemispherical convex surface, the surface of the sputum suction nozzle body 102 is wrapped with a soft ciliary scraping layer 104, and a plurality of absorption holes 105 of varying sizes are also distributed on the sputum suction nozzle body 102, and the sputum suction nozzle tail 103 is inserted into one end of the inner catheter 201. In this embodiment, the sputum suction nozzle head 101 is hemispherical, relatively round and blunt, which can reduce the stimulation to the airway, the soft ciliary scraping layer 104 can remove the sticky sputum crust in the airway, and the sputum suction nozzle head 102 and the sputum suction nozzle body 103 are both provided with absorption holes 105 of varying sizes to improve the sputum removal ability.

[0029] The flow guide tube 2 is in the shape of a round tube, made of soft plastic, with strong softness, and a scale is set on the outer surface, so that the depth of insertion into the airway can be evaluated. The other end of the inner conduit 201 is provided with a hard connector so that the inner conduit 201 is threadedly connected with the first connecting portion 31. The flow guide tube 2 is divided into an inner conduit 201 and an outer conduit 202, the inner conduit 201 is connected with the tail 103 of the sputum suction nozzle, and is a channel for sputum to pass through, and the outer conduit 202 is an airway humidification liquid accommodating chamber, and an outer conduit outflow hole 203 and an outer conduit inflow hole 204 are set, and the outer conduit inflow hole 204 is connected with the airway humidification liquid discharge hole 422 by a first connecting pipe 424, and the first connecting pipe 424 is a soft plastic tube, and a valve 423 is set thereon, which can control the flow of the airway humidification liquid. The valve 423 is closed when the airway care device is not in operation or is simply suctioning phlegm; the valve 423 is open when the airway care device is in normal operation (airway humidification + suctioning phlegm), and the flow rate can be adjusted. The airway humidification liquid can be injected from the airway humidification liquid injection hole 421 as needed and in quantity.

[0030] The first connection part 31 and the third connection part 33 of the three-way pipe 3 have the same caliber, and the caliber of the second connection part 32 is twice the caliber of the first connection part 31. The caliber of the second connection part 32 is relatively large, which can facilitate the sputum to flow smoothly and quickly into the sputum collecting bottle 5 under the action of gravity, and the transition point between the second connection part 32 and the third connection part 33 is a slope structure, and some splashed sputum can flow into the sputum collecting bottle 5 again along the slope; a special Y-shaped structure is adopted instead of an ordinary T-shaped structure to avoid the second connection part 32 and the third connection part 33 from being opposite to each other, thereby reducing the possibility of sputum splashing in the sputum collecting bottle 5 and contaminating the negative pressure device 41.

[0031] The negative pressure device 41 is located above the sputum collecting bottle 5. The negative pressure device 41 has a spherical air bag appearance. The negative pressure device 41 and the airway humidification liquid containing device 42 do not communicate with each other. The main body of the negative pressure device 41 is an extrusion air bag 411, and a built-in spring 412 is provided. One end of the built-in spring 412 is connected to the inner wall of the extrusion balloon 411, and the other end is connected to the outer wall of the airway humidification liquid containing device 42, which can increase the negative pressure attraction and reduce the work done by the hand. The negative pressure device 41 is connected to the third connecting part 33 of the three-way pipe 3 through the exhaust hole 413. The airway humidification liquid containing device 42 is hidden in the core of the negative pressure device 41, and is in the shape of a soft plastic bag, with an airway humidification liquid injection hole 421 at the top and an airway humidification liquid discharge hole 422 at the bottom. In this model, this design not only saves space, but also realizes the unification of functions, and can be operated by a single person, which is convenient and fast.

[0032] The sputum collecting bottle 5 comprises a top cover 501, a bottom cover 502 and a bottle body 506. The top of the bottle body 506 is connected to the top cover 501 by a spiral pattern, and the bottom of the bottle body 506 is connected to the bottom cover 502 by a spiral pattern. The bottle body 506 is detachable and easy to clean. The top cover 501 is provided with a sputum inflow hole 504, which is connected and communicated with the second connecting portion 32. The bottom cover 502 is provided with a sputum discharge hole 503, which is connected to the second connecting pipe 505. The bottle body 506 is a cylindrical transparent structure. The top cover 501 and the bottom cover 502 are tightly connected to the bottle body 506 by a spiral pattern structure. The side wall of the bottle body 506 is marked with scales, which can quantify the sputum and evaluate the condition. If the sputum exceeds 2 / 3 of the volume of the sputum collecting bottle 5, the sputum needs to be discharged through the fifth connecting pipe 505. The sputum collecting bottle 5 is a detachable device, which is easy to clean and reduces contamination such as bacteria.

[0033] like Figure 4As shown, the filtering device includes a first filter 701 and a second filter 702. The aperture of the first filter 701 is smaller than that of the second filter 702. The first filter 701 is a dome-shaped structure, and the second filter 702 is a conical structure. The left end of the first filter 701 and the left end of the second filter 702 are fixed on the left end fixing member 703, and the right end of the first filter 701 and the right end of the second filter 702 are fixed on the right end fixing member 703. The filtering device filters the sputum caused by negative pressure suction and the splashed sputum. The sputum is focused on the center point of the filter due to gravity and enters the sputum collecting bottle 5 again. The double-layer filter plays a double filtering role.

[0034] When in use, the guide tube 2 is inserted into the tracheostomy opening, the valve 423 is loosened, and then the negative pressure device 41 is manually squeezed in the direction of the action of the built-in spring 412. The negative pressure device 41 relies on the squeezing effect to allow the airway humidification liquid in the airway humidification liquid containing device 42 to enter the outer catheter 202 through the airway humidification liquid discharge hole 422, the first connecting tube 424 and the outer catheter inflow hole 204 in sequence, and then flow out through the outer catheter outflow hole 203 on the outer catheter 202, thereby achieving airway humidification.

[0035] The negative pressure device 41 generates negative pressure, and sputum enters the inner catheter 201 by the negative pressure, and enters the sputum collecting bottle 5 through the second connecting part 32 by gravity. The second connecting part 32 has a large diameter, and the transition between the second connecting part 32 and the third connecting part 33 is a slope structure, which can further reduce the possibility of sputum entering the negative pressure device 41 along the negative pressure direction. The filter device 7 is arranged at the third connecting part 33 to intercept sputum from entering the negative pressure device 41 to the greatest extent, and the filter device 7 can be disassembled for easy cleaning.

[0036] Although the specific embodiments of the present invention are described above, those skilled in the art should understand that these are only examples, and the protection scope of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
