Description

Technical Field

[0001] The invention relates to a sputum suction structure, in particular to a sputum suction structure for a tracheotomy tube. Background Art

[0002] The use of a tracheostomy tube is achieved by performing a tracheotomy (tracheotomy) operation, inserting the tracheostomy tube into the stoma of the patient's neck, and then connecting the breathing tube to the joint at the front end of the tracheostomy tube to enable the patient to breathe smoothly.

[0003] Furthermore, after the patient is fitted with a tracheostomy tube, the air bag of the tracheostomy tube will be against the inner wall of the trachea, causing the patient's sputum to accumulate above the air bag. The accumulated sputum is likely to increase the risk of infection and airway obstruction, so suction is required. Currently, the suction of the tracheostomy tube is to fit a suction tube on the outside of the air bag to suction a fixed point. Since the end of the suction tube needs to avoid the upper edge of the air bag, the dirt and sputum accumulated on the upper edge of the air bag cannot be extracted, and the sputum outside the suction tube cannot be cleared, causing the sputum to accumulate and remain above the air bag.

[0004] In view of this, the inventor has devoted himself to studying the above-mentioned prior art and has applied theoretical knowledge to try his best to solve the above-mentioned problems, which has become the goal of the inventor's improvement. Summary of the invention

[0005] One purpose of the present invention is to provide a sputum suction structure for a tracheostomy tube, so as to suction sputum at the upper edge of the airbag over a larger range, thereby achieving the effect of effectively and surely clearing sputum at the upper edge of the airbag.

[0006] In order to achieve the above-mentioned purpose, the present invention is a sputum suction structure for a tracheostomy tube, comprising an insertion tube, a movable baffle, a suction sheet and a sputum suction tube. The insertion tube comprises an insertion section, a joint section connected to the insertion section and an air bag arranged on the insertion section. The movable baffle is arranged between the insertion section and the joint section. The suction sheet is arranged on the upper end edge of the air bag facing the insertion section and encloses the outer edge surface of at least a part of the insertion section. The suction sheet comprises a joint portion located on one side and a suction portion located on the other side. The joint portion is in close contact with the outer edge surface of the insertion section and has a sputum suction interface connected to the suction portion, a suction space is formed between the suction portion and the upper end edge of the air bag, and side suction ports connected to the suction space are respectively provided on both sides of the suction portion. One end of the sputum suction tube is inserted into the sputum suction interface, and the other end extends and passes through the outer side of the movable baffle.

[0007] In one embodiment of the present invention, the sputum suction structure of the tracheostomy tube further includes an inflation tube, which penetrates into the insertion section and is connected to the air bag.

[0008] In one embodiment of the present invention, the sputum suction port is disposed on a concave arc surface formed on the inner wall of the suction piece facing the insertion section, and a convex arc surface is formed on the outer surface of the suction piece away from the insertion section.

[0009] In one embodiment of the present invention, the sputum suction port extends from the connecting portion to the suction portion.

[0010] In one embodiment of the present invention, the suction piece is a semicircular ring piece.

[0011] In one embodiment of the present invention, the suction sheet has an extension angle, and the extension angle is no greater than 180 degrees.

[0012] In one embodiment of the present invention, a step is provided between the combining portion and the suction portion.

[0013] In one embodiment of the present invention, the connecting portion includes a convex surface and a plurality of blocking ribs connected to the convex surface. The plurality of blocking ribs are located on both sides of the suction sheet and form side suction ports on an outer side respectively.

[0014] In one embodiment of the present invention, each blocking rib extends from the convex surface and forms a side flow channel with the side edge of the suction plate.

[0015] In one embodiment of the present invention, a gap is maintained between a side edge and an upper edge of the suction sheet.

[0016] Compared with the known technology, the sputum suction structure of the tracheostomy tube of the present invention is provided with a suction plate. Since the suction plate can cover the sputum suction tube and the tube body of the insertion tube, it is closer to the upper outer side of the airbag. In addition, since the suction plate is provided with a sputum suction interface and side suction ports are provided on both sides, there is no need to fit the sputum suction tube on the outer side of the airbag like a traditional tracheostomy tube; accordingly, the sputum above the airbag will be sucked into the suction space from the bottom side of the suction plate and the side suction ports on both sides by the negative pressure suction of the sputum suction tube, and then enter the sputum suction interface, and finally flow into the sputum suction tube and be pumped to the outside, so the sputum above the airbag can be suctioned over a larger range, so the sputum above the airbag can be more effectively and reliably cleared, thereby increasing the practicality of the present invention.

[0049] The detailed description and technical contents of the present invention are described as follows with reference to the accompanying drawings. However, the accompanying drawings are only provided for reference and description and are not intended to limit the present invention.

[0050] Please refer to Figure 1 and Figure 2 , is a schematic diagram of the three-dimensional appearance of the tracheostomy tube of the present invention and a schematic diagram of the combination of the suction piece in the present invention. The sputum suction structure of the tracheostomy tube 1 of the present invention includes an insertion tube 10, a movable baffle 20, a suction piece 30 and a sputum suction tube 40. The movable baffle 20 is sleeved outside the insertion tube 10. The suction piece 30 is combined on the insertion tube 10. The sputum suction tube 40 is inserted into the suction piece 30 and extends out of the movable baffle 20 for connecting to a suction device (not shown); accordingly, the sputum suction tube 40 can extract sputum accumulated at the bottom of the suction piece 30.

[0051] Specifically, the insertion tube 10 includes an insertion section 11, a joint section 12 connected to the insertion section 11, and an air bag 13 disposed on the insertion section 11. In this embodiment, the tracheostomy tube 1 further includes an inflation tube 50. The inflation tube 50 penetrates the insertion section 11 and is connected to the air bag 13, and is used to connect to an air supply device (not shown); accordingly, external gas can flow from the inflation tube 50 into the air bag 13, so that the air bag 13 is inflated and then the patient's trachea is opened.

[0052] The movable baffle 20 is disposed between the insertion section 11 and the joint section 12. In actual use, the movable baffle 20 is placed outside the stoma of the patient's throat to position the insertion tube 10.

[0053] Furthermore, the suction sheet 30 is disposed on an upper edge 131 of the air bag 13 facing the insertion section 11 and surrounds at least a portion of the outer edge of the insertion section 11. In addition, the sputum suction tube 40 is inserted on one side of the suction sheet 30 and extends through the movable baffle 20. The combination structure of the suction sheet 30 and the sputum suction tube 40 is described in more detail below.

[0054] Please refer to Figures 3 to 6 , which is a three-dimensional appearance schematic diagram of the inner side direction of the suction sheet in the present invention and a three-dimensional appearance schematic diagram of the tracheostomy tube in different directions. In this embodiment, the suction sheet 30 is a semicircular ring sheet. The suction sheet 30 includes a joint portion 31 located on one side and a suction portion 32 located on the other side. The joint portion 31 is in close contact with the outer edge surface of the insertion section 11 and has a sputum suction interface 311 connected to the suction portion 32.

[0055] It should be noted that the suction sheet 30 has an extension angle A, and the extension angle A is not greater than 180 degrees. In addition, a gap 300 is maintained between a side edge of the suction sheet 30 and the upper edge 131 (see also Figure 1 Thus, a suction space 100 is formed between the suction portion 32 and the upper edge 131 of the airbag 13 (see Figure 4 ), and both sides of the suction portion 32 respectively have a suction port 321 connected to the suction space 100.

[0056] More specifically, there is a step between the joint portion 31 and the suction portion 32. The joint portion 31 includes a convex surface 312 and a plurality of blocking ribs 313 connected to the convex surface 312. The blocking ribs 313 are located on both sides of the suction sheet 30 and form side suction ports 321 on an outer side thereof.

[0057] In addition, each blocking rib 313 extends from the convex surface 312 and forms a side channel 322 with the side edge of the suction sheet 30. It should be noted that the side channel 322 is provided to limit the path of sputum entering the sputum suction port 311, and then the sputum is concentrated from the side channel 322 to enter the sputum suction port 311 under a certain suction force.

[0058] Furthermore, there is a gap between the side suction port 321 of the suction part 32 and the phlegm suction port 311, so negative pressure is generated during suction, causing deformation of the suction part 32. In addition, the provision of the blocking ribs 313 can also prevent the suction part 32 from being deformed due to suction, thereby preventing the situation where suction cannot be performed.

[0059] In one embodiment of the present invention, the suction port 311 extends from the joint portion 31 to the suction portion 32. The suction port 311 is configured to be a concave arc surface formed on an inner wall of the suction sheet 30 facing the insertion section 11, and a convex arc surface is formed on an outer surface of the suction sheet 30 away from the insertion section 11.

[0060] Please also refer to Figure 7 and Figure 8 , is a schematic diagram of the combination of the suction piece and the sputum suction tube in the present invention and a schematic diagram of the sputum flow direction during sputum suction. The suction piece 30 includes a connection portion 31 and a suction portion 32. The suction piece 30 is fixed to the insertion tube 10 by the connection portion 31 being in close contact with the outer edge surface of the insertion section 11, and the connection portion 31 is provided with a sputum suction interface 311 connected to the suction portion 32. One end of the sputum suction tube 40 is inserted into the sputum suction interface 311, and the other end extends and passes through an outer side of the movable baffle 20 (refer to FIG. 2 ). Figure 1In addition, the joint portion 31 includes a plurality of baffle ribs 313. The two outer sides of the baffle ribs 313 are respectively formed as a side suction port 321. Each baffle rib 313 and the side edge of the suction sheet 30 form a side flow channel 322.

[0061] When performing the sputum suction operation, the suction device is activated to generate negative pressure suction to remove the sputum accumulated above the air bag 13 through the sputum suction tube 40 (see Figure 1 ) sputum. In other words, the sputum retained above the airbag 13 will be sucked by the negative pressure of the sputum suction tube 40 and enter the suction part 32 from the bottom side and the side suction ports 321 on both sides of the suction sheet 30 (see also Figure 6 ), and flows through the side channel 322 and enters the sputum suction port 311, and finally flows into the sputum suction tube 40 and is pumped to the outside.

[0062] It should be noted that, since the sputum above the airbag 13 can enter the suction portion 32 from the side suction ports 321 on both sides of the suction sheet 30, the sputum above the airbag 13 can be suctioned over a larger range, thereby more effectively and reliably clearing the sputum above the airbag.

[0063] Please refer to Fig. 9 , is a schematic diagram of the tracheostomy tube of the present invention sucking waste when the patient is sitting. When the tracheostomy tube of the present invention is used, waste will accumulate above the airbag 13 and be located at the bottom side of the suction sheet 30. When suctioning sputum, waste will enter the suction part 32 from the bottom side of the suction sheet 30 (see also Figure 6 ), and flows through the side channel 322 and enters the sputum suction port 311, and finally flows into the sputum suction tube 40 and is pumped to the outside (see also Figure 7 and Figure 8 ).

[0064] Please refer to Fig.10 , is a schematic diagram of the tracheostomy tube of the present invention sucking waste when the patient lies down. When the tracheostomy tube of the present invention is used, waste will accumulate above the airbag 13 and on one side of the suction sheet 30. When suctioning sputum, under the negative pressure suction of the suction tube 40, waste will enter the suction part 32 from the side suction port 321 of the suction sheet 30 (see also Figure 7 ), then flows into the suction tube 40 and is pumped to the outside (see also Figure 8 ).

[0065] Please refer to Fig.11 , is a three-dimensional schematic diagram of another embodiment of the suction sheet of the present invention. In this embodiment, the suction sheet 30a includes a joint portion 31a located on one side and a suction portion 32a located on the other side. The joint portion 31a is provided with a sputum suction port 311a in the middle thereof, which is connected to the suction portion 32a. In addition, there is a gap between the joint portion 31a and the suction portion 32a.

[0066] The difference between this embodiment and the previous embodiment is that the suction sheet 30a is formed with a protrusion 33a on both sides of the bottom edge of the suction portion 32a, and a suction port 321a is formed between the joint portion 31a and the protrusion 33a to communicate with the suction portion 32a.

[0067] Please refer to Fig.12 , is a three-dimensional schematic diagram of another embodiment of the suction sheet of the present invention. In this embodiment, the suction sheet 30b includes a connecting portion 31b located on one side and a suction portion 32b located on the other side. The connecting portion 31b is provided with a phlegm suction port 311b connected to the suction portion 32b in the middle. In addition, there is a gap between the connecting portion 31b and the suction portion 32b.

[0068] The difference between this embodiment and the previous embodiment is that the suction sheet 30b is formed with a protrusion 33b at a distance between the bottom edge of the suction portion 32b and the two sides of the suction portion 32b. A suction port 321b is formed between the joint portion 31b and the protrusion 33b to communicate with the suction portion 32b.

[0069] The above description is only a preferred embodiment of the present invention and is not intended to limit the patent scope of the present invention. Other equivalent changes that apply the patent spirit of the present invention should all fall within the patent scope of the present invention.
