Referring to fig. 1, the tracheostomy cannula includes: the tracheostomy tube 100 and the plugging piece 200, the plugging piece 200 includes pipe box 300 and shutoff portion 400, pipe box 300 can cup joint on tracheostomy tube 100, shutoff portion 400 sets up the exit end at pipe box 300, and pipe box 300 can be adjusted through shutoff portion 400 to reduce the export size of pipe box 300 gradually.

When the tracheostomy tube 100 needs to be plugged, the plugging piece 200 is sleeved on the tracheostomy tube 100, the tube sleeve 300 is matched with the tracheostomy tube 100, and the tube sleeve 300 and the tracheostomy tube 100 can adopt a buckling connection mode, a threaded connection mode and the like, so that the tube sleeve 300 is tightly sleeved on the tracheostomy tube 100, and the phenomenon that the tracheostomy tube falls off due to cough of a patient is avoided. The size of the outlet of the pipe sleeve 300 is changed by adjusting the plugging area of the plugging part 400, so that the air input of the air cutting pipe 100 is adjusted, medical staff can conveniently know whether a patient breathes normally under the condition of different air input until the patient can breathe normally after being plugged completely, and then the pipe can be pulled out. The utility model discloses a shutoff portion 400 can progressive improvement shutoff face, reaches the purpose of stifled pipe gradually.

In the current clinical process, the pipe blocking operation is generally gradually transited from 1/4 to the pipe blocking 1/2, the pipe blocking 3/4 and then to the pipe blocking completely. The blocking part 400 comprises blocking areas of four gears, and each gear corresponds to 1/4 blocking surfaces, 1/2 blocking surfaces, 3/4 blocking surfaces and full sealing respectively. The utility model discloses in, shutoff portion 400 includes four gears, in clinical process, when the stifled pipe of examination that will carry out the difference, only need transfer the stifled big or small demand of pipe that the gear that corresponds reaches the demand, satisfy stifled pipe 1/4, stifled pipe 1/2, stifled pipe 3/4, four stifled pipe demands of full stifled in the clinical process.

As shown in fig. 2 to 4, the outlet end of the pipe sleeve 300 is circular, the blocking portion 400 is composed of four fan-shaped surfaces with equal area, the four fan-shaped surfaces can form a circular surface, the four fan-shaped surfaces are respectively a first fan-shaped surface 410, a second fan-shaped surface 420, a third fan-shaped surface 430 and a fourth fan-shaped surface 440 which are sequentially arranged, the bottom ends of the first fan-shaped surface 410, the second fan-shaped surface 420, the third fan-shaped surface 430 and the fourth fan-shaped surface 440 are connected together through a rotation central shaft 450, the top end of the rotation central shaft 450 is provided with a rotation handle 451, and the outer edge of the first fan-shaped surface 410 is connected with the pipe sleeve 300.

In the present embodiment, the blocking portion 400 is composed of four fan-shaped surfaces with equal area, wherein the bottom ends of the second fan-shaped surface 420, the third fan-shaped surface 430 and the fourth fan-shaped surface 440 can rotate around the central rotation axis 450.

As shown in fig. 3 and 4, when tube 1/4 is to be plugged, the four sectors are rotated and overlapped together to block only 1/4 of the outlet of tube sleeve 300, so as to meet the requirement of plugging tube 1/4.

When the pipe 1/2 needs to be plugged, the second sector 420 is screwed out, and the first sector 410 and the second sector 420 block the 1/2 of the outlet of the pipe sleeve 300, so that the requirement of plugging the pipe 1/2 is met.

When the pipe 3/4 needs to be plugged, the third sector 430 is screwed out, and the first sector 410, the second sector 420 and the third sector 430 block the 3/4 of the outlet of the pipe sleeve 300, so that the requirement of plugging the pipe 3/4 is met.

When the full blocking is required, the first sector 410, the second sector 420, the third sector 430 and the fourth sector 440 are all unfolded to form a circular surface, so that the outlet of the pipe sleeve 300 can be completely blocked.

The first sector 410, the second sector 420, the third sector 430 and the fourth sector 440 preferably have a sector greater than 1/4 circles, so that when the sectors are rotated out, a certain overlap is formed between the two sectors, thereby improving the sealing effect.

As shown in fig. 5, the outlet end of the pipe sleeve 300 is square, the plugging portion 400 is composed of four square blocks with equal area, which are a first block 460, a second block 470, a third block 480 and a fourth block 490 arranged from bottom to top in sequence, the adjacent first block 460, second block 470, third block 480 and fourth block 490 are connected in a sliding manner, and the head and the tail ends of the first block 460 and the second block 470 are provided with driving mechanisms, and the tail end of the fourth block 490 is connected with the pipe sleeve.

The outlet end of the sleeve 300 of the block piece of the second embodiment is square, and when the pipe needs to be blocked, the block piece 200 is sleeved on the tracheostomy tube 100.

When the pipe 1/4 needs to be blocked, the four square blocks are overlapped together to block one fourth of the outlet of the pipe sleeve 300, so that the pipe blocking requirement of the pipe blocking 1/4 is met.

When the tube 1/2 is to be plugged, the first block 460 is pulled out, and the first block 460 and the fourth block 490 block 1/2 of the outlet of the tube housing 300, so as to meet the requirement of plugging the tube 1/2.

When the tube 3/4 is to be blocked, the second block 470 is pulled out, and the first block 460, the second block 470 and the fourth block 490 block the tube 3/4 at the outlet of the tube housing 300, so as to meet the requirement of blocking the tube 3/4.

When the full blocking is to be performed, the first block 460, the second block 470 and the third block 480 are all pulled out, and the outlet of the pipe sleeve 300 is all blocked by the surface formed by the first block 460, the second block 470, the third block 480 and the fourth block 490.

Fig. 6 shows a connection manner of two adjacent blocks, taking the connection of the first block 460 and the second block 470 as an example, the protrusion 461 of the first block 460 is slidably connected in the groove 471 of the second block 470, the groove 471 is not through, and the second block 470 is pulled out together when the first block 460 is pulled continuously when sliding to the limit.

The patient who uses the tracheostomy tube often is the patient that the lung infects comparatively badly, and the lung can produce a large amount of sputum, and the patient can be when the time cough just coughs, and in the time of the patient coughs, the sputum probably entered the tracheostomy tube, consequently all will carry out complementary phlegm operation of inhaling among the general treatment process. At present, the sputum suction tube is generally extended into the lung of a patient from the tracheostomy tube, and the sputum suction is repeatedly carried out for many times. The tracheostomy tube has a small opening, which is easy to cause pollution.

In this application, the tube sleeve 300 is provided with a sputum suction adapter 500, and the sputum suction adapter 500 is provided with a sealing cap (not shown in the figure). When the sputum suction operation is carried out, the sealing cap on 500 is taken down, the sputum suction pipe connected with the negative pressure is directly inserted into the air flue for sputum suction, and after the operation is finished, the cap is covered. Or the cap on 500 is taken down and connected with a closed sputum suction tube for sputum suction. Can also take off shutoff piece 200, wash shutoff piece 200, avoid the sputum of adhesion to block up the condition of air flue or cause the air flue to infect.

Of course, the present invention is not limited to the above-mentioned embodiments, and those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of the present invention, and such equivalent modifications or substitutions are included in the scope defined by the claims of the present application.
