[0026] See Figure 1-4 In a first aspect of an embodiment of the utility model, a tracheostomy tube connector 1 is provided, comprising a first end portion 11 and a second end portion 12, wherein the first end portion 11 is used for detachably connecting to the tracheostomy tube body 2, and the second end portion 12 is provided with a flow guide structure 121, and a first opening 1211 is provided on a side of the flow guide structure 121 away from the first end portion 11, and the first opening 1211 connects the inside of the tracheostomy tube connector 1 with the outside world.

[0027] In an embodiment of the present utility model, the tracheostomy tube connector 1 includes a first end 11 and a second end 12, wherein the first end 11 and the tracheostomy tube body 2 are detachably connected. When the first end 11 and the tracheostomy tube body 2 are connected, the secretions flowing out of the tracheostomy tube body 2 will flow into the interior of the tracheostomy tube connector 1 through the first end 11. In addition, since the second end 12 of the tracheostomy tube is provided with a guide structure 121, and the guide structure 121 is provided with a first opening 1211 on the side away from the first end 11, therefore, under the guiding action of the guide structure 121, the secretions flowing into the interior of the tracheostomy tube connector 1 can be collected in the guide structure 121 and concentratedly flow to the outside from the first opening 1211, which can effectively prevent the secretions from contacting medical staff, etc., and is safe and reliable.

[0028] Furthermore, the tracheotomy tube connector 1 includes a straight portion and a curved portion, the straight portion is connected to the curved portion, and the first end portion 11 is arranged at one end of the straight portion away from the curved portion; the inner side wall of the curved portion forms a flow guide structure 121, and the first opening 1211 is located on the side of the curved portion away from the straight portion.

[0029] Specifically, the tracheostomy tube connector 1 includes two parts: a straight portion and a curved portion, wherein the straight portion includes a first end portion 11 and a first main body portion, and the curved portion is the second end portion 12, and the first end portion 11, the first main body portion, and the second end portion 12 are arranged in sequence. The curved portion is formed by bending, and there is a certain angular relationship between the extension direction of the curved portion and the extension direction of the straight portion. The guide structure 121 is formed by the inner side wall formed by the bending of the curved portion, and the first opening 1211 is located on the side of the curved portion away from the straight portion. When the first end portion 11 and the tracheostomy tube body 2 are connected, the secretions flowing out of the tracheostomy tube body 2 will flow through the first end portion 11 to the inner side wall of the straight portion of the tracheostomy tube, and then flow to the inner side wall of the curved portion. Due to the guiding effect of the inner side wall of the curved portion, the secretions can be concentrated from the first opening 1211 to flow to the outside world, which can effectively prevent the secretions from contacting medical staff, etc., and is safe and reliable.

[0030] Furthermore, the first opening 1211 is arranged to be inclined relative to the straight portion, and there is an angle of n° between the plane where the first opening 1211 is located and the straight portion, where 90<n<180.

[0031] Specifically, the first opening 1211 is provided on a side of the curved portion away from the straight portion, and the angle between the first opening 1211 and the straight portion can be 91°, 100°, 110°, 120°, 130°, 140°, 150°, 160°, or 170°, etc. The curved portion is formed by bending outward from one end of the first main portion away from the first end portion 11, and the first opening 1211 of the curved portion is inclined relative to the straight portion. Therefore, when secretions flow toward the first opening 1211, they are blocked by the inner sidewall of the curved portion near the first opening 1211, so that the secretions can flow outward from the first opening 1211, effectively preventing the secretions from contacting medical personnel, etc., and ensuring safety and reliability.

[0032] Furthermore, in some embodiments, a second opening 13 is provided on the side wall of the tracheotomy tube connector 1 to connect the interior with the outside.

[0033] Specifically, the second opening 13 can be provided on the side wall of the curved portion, the side wall of the straight portion, or the side wall at the junction of the curved portion and the straight portion. The embodiment of the utility model does not specifically limit the shape of the second opening 13. The second opening 13 can be adapted to different patient postures, such as when the patient is lying flat or lying on their side, so that secretions in the tracheostomy tube can be easily discharged through the second opening 13.

[0034] Furthermore, the second aspect of the embodiment of the utility model provides a tracheostomy tube, including a tracheostomy tube body 2 and a tracheostomy tube connector 1 as above, the tracheostomy tube body 2 has a third end 21, the first end 11 and the third end 21 are detachably connected, and the first end 11 and the third end 21 are connected to connect the interior of the tracheostomy tube body 2 and the interior of the tracheostomy tube connector 1.

[0035] In an embodiment of the present invention, the tracheostomy tube includes a tracheostomy tube body 2 and a tracheostomy tube connector 1 as described above. The tracheostomy tube body 2 has a third end 21, and the first end 11 of the tracheostomy tube connector 1 can be detachably connected to the first end 11 of the tracheostomy tube body 2. When the first end 11 and the third end 21 are connected, the secretions flowing out from the inside of the tracheostomy tube body 2 will flow into the inside of the tracheostomy tube connector 1 through the first end 11 and the third end 21 that pass through. In addition, since the second end 12 of the tracheostomy tube is provided with a guide structure 121, and the guide structure 121 is provided with a first opening 1211 on the side away from the first end 11, therefore, under the guiding action of the guide structure 121, the secretions flowing into the inside of the tracheostomy tube connector 1 can be collected in the guide structure 121 and concentratedly flow to the outside from the first opening 1211, which can effectively prevent the secretions from contacting medical staff, etc., and is safe and reliable.

[0036] Furthermore, in some embodiments, the first end portion 11 is provided with a first snap-fit structure, and the third end portion 21 is provided with a second snap-fit structure, wherein the first snap-fit structure is connected to the second snap-fit structure. The first snap-fit structure and the second snap-fit structure enable a detachable connection between the first end portion 11 and the third end portion 21, thereby achieving fixed assembly of the tracheostomy tube connector 1 and the tracheostomy tube body 2.

[0037] In other embodiments, the first end portion 11 and the second end portion 12 may be assembled and connected by other detachable means such as threaded connection, bonding, etc.

[0038] Furthermore, in some embodiments, the first snap-fitting structure includes a snap-fitting groove 111 formed in the first end portion 11 , and the second snap-fitting structure includes a buckle 211 protruding from an outer side wall of the third end portion 21 , and the buckle 211 is snap-fitted to the snap-fitting groove 111 .

[0039] Specifically, the buckle 211 is trapezoidal and gradually tapers outward from the outer side wall of the third end portion 21. Therefore, when the first end portion 11 and the third end portion 21 are connected or separated, it is convenient for the top of the buckle 211 to pass through the snap-fit groove 111, thereby facilitating the assembly and disassembly of the two, reducing the difficulty of assembling and disassembling the tracheostomy tube body 2 and the tracheostomy tube connector 1, and facilitating the replacement of the tracheostomy tube connector 1. In addition, the third end portion 21 is inserted into the interior of the first end portion 11, that is, the outer side wall of the third end portion 21 is in contact with the inner side wall of the first end portion 11. Therefore, even if the first end portion 11 is provided with a snap-fit groove 111 that communicates with the outside world, the sealing of the connection between the first end portion 11 and the third end portion 21 can still be guaranteed to a certain extent.

[0040] In some embodiments, the first snap-fit structure includes a snap 211 protruding from the inner sidewall of the first end portion 11, and the second snap-fit structure includes a snap-fit groove 111 formed in the second end portion 12, with the snap 211 snapping into the snap-fit groove 111. Furthermore, the third end portion 21 is disposed inside the first end portion 11, i.e., the outer sidewall of the third end portion 21 abuts against the inner sidewall of the first end portion 11, thereby similarly achieving a detachable connection between the tracheostomy tube body 2 and the tracheostomy tube connector 1 and ensuring a tight seal at the connection between the two.

[0041] Furthermore, in some embodiments, the clamping groove 111 extends along the circumference of the first end portion 11 , and the extension length of the clamping groove 111 is a preset length.

[0042] Specifically, the length extension direction of the snap-fit groove 111 is parallel to the circumferential direction of the first end portion 11. The buckle 211 is snap-fitted into the snap-fit groove 111. When the tracheostomy tube body 2 and the tracheostomy tube connector 1 are driven to rotate relative to each other, the buckle 211 can move along the length extension direction of the snap-fit groove 111. However, since the extension length of the snap-fit groove 111 is a preset length, the movement distance of the buckle 211 is limited. In the process of driving the tracheostomy tube connector 1 to rotate relative to the tracheostomy tube body 2 in a certain direction, when the buckle 211 abuts against one of the side walls of the snap groove 111, the tracheostomy tube connector 1 can no longer rotate in this direction due to the action of the buckle 211 and the side wall of the snap groove 111, so that the tracheostomy tube connector 1 and the tracheostomy tube body 2 can no longer rotate relative to each other. Therefore, by limiting the circumferential extension length of the snap groove 111 at the first end 11, the rotational freedom of the tracheostomy tube connector 1 and the tracheostomy tube body 2 can be limited, so that the tracheostomy tube connector 1 and the tracheostomy tube body 2 cannot rotate 360°. Therefore, when discharging secretions, the angle can be quickly adjusted to quickly discharge the secretions.

[0043] It should be noted that, in actual practice, the extension length of the engaging slot 111 is determined by actual needs, that is, the present invention does not impose any specific limitation on the preset length.

[0044] It can be understood that for the embodiment in which the snap-in groove 111 is arranged at the third end 21, the rotational freedom of the tracheotomy tube connector 1 and the tracheotomy tube body 2 can also be limited by limiting the extension length of the snap-in groove 111 at the third end 21, which will not be elaborated here.

[0045] Furthermore, in some embodiments, two first snap-fit structures are provided at intervals on the first end portion 11, and two second snap-fit structures are provided on the third end portion 21, corresponding to the two first snap-fit structures. The first snap-fit structures and the second snap-fit structures are connected to each other. By providing two first snap-fit structures and two second snap-fit structures, the connection stability between the first end portion 11 and the third end portion 21 can be improved, thereby improving the connection stability between the tracheostomy tube body 2 and the tracheostomy tube connector 1.

[0046] Furthermore, in some embodiments, the two first clamping structures correspond to two clamping slots 111 , and the two second clamping structures correspond to two buckles 211 , and the clamping slots 111 and the buckles 211 correspond one to one.

[0047] Furthermore, in some embodiments, the two snap-fit grooves 111 have the same circumferential extension length in the first end portion 11. Therefore, when one of the snaps 211 abuts against the groove wall of one of the snap-fit grooves 111, thereby limiting the relative rotation of the tracheostomy tube body 2 and the tracheostomy tube connector 1, the other snap 211 can also abut against the groove wall of the other snap-fit groove 111, thereby enhancing the force limiting the rotation.

[0048] It is understood that, for the embodiment in which the buckle 211 is provided at the first end portion 11 and the engaging groove 111 is provided at the third end portion 21, two spaced apart buckles 211 and two spaced apart engaging grooves 111 can also be provided, which can also improve the connection stability between the tracheostomy tube body 2 and the tracheostomy tube connector 1. Furthermore, the two engaging grooves 111 can extend the same length in the circumferential direction of the third end portion 21, which can also enhance the force that restricts rotation.

[0049] It should be noted that the embodiment of the present invention does not impose any specific limitation on the specific arrangement positions of the two first clamping structures. For example, the two first clamping structures can be arranged opposite to each other or adjacently spaced apart.

[0050] Furthermore, the tracheotomy tube connector 1 also includes a first main body connected between the first end 11 and the second end 12, the first main body and / or the first end 11 include two first flexible pressing portions 14 arranged opposite to each other, the third end 21 includes two second flexible pressing portions 22 corresponding to the two first flexible pressing portions 14, and there is a gap between the two second flexible pressing portions 22, the third end 21 is passed through the first end 11, and the first flexible pressing portion 14 and the second flexible pressing portion 22 are correspondingly abutted.

[0051] Specifically, the straight portion of the tracheostomy tube connector 1 is cylindrical, and two opposing first flexible pressing portions 14 are provided on the straight portion of the tracheostomy tube connector 1. The two second flexible pressing portions 22 of the tracheostomy tube body 2 are both arc-shaped, and there is a certain distance between the two second flexible pressing portions 22. The tracheostomy tube body 2 is inserted into the tracheostomy tube connector 1, and the first flexible pressing portion 14 and the second flexible pressing portion 22 are correspondingly abutted. Therefore, by pressing the two second flexible pressing portions 22, the two second flexible pressing portions 22 are relatively close, which facilitates the insertion of the third end portion 21 into the first end portion 11 and facilitates the connection of the tracheostomy tube body 2 to the tracheostomy tube connector 1. When the tracheostomy tube body 2 and the tracheostomy tube connector 1 are to be separated, the first flexible pressing portion 14 of the tracheostomy tube connector 1 can be pressed inward, so that the first flexible pressing portion 14 is deformed inward, which can drive the two second flexible pressing portions 22 of the tracheostomy tube connector 1 to deform, so that the two second flexible pressing portions 22 are close to each other, thereby facilitating the disassembly and separation of the tracheostomy tube body 2 and the tracheostomy tube connector 1.

[0052] Furthermore, the tracheostomy tube body 2 also includes a second main body portion connected to the third end portion 21 on a side away from the tracheostomy tube connector 1. A limiting flange 23 is also provided between the third end portion 21 and the second main body portion. The limiting flange 23 extends along the circumference of the third end portion 21, and the limiting flange 23 can be arc-shaped or ring-shaped. When the tracheostomy tube body 2 and the tracheostomy tube connector 1 are connected, the first end portion 11 abuts against the limiting flange 23, and since the first clamping structure and the second clamping structure are provided, the connection stability of the tracheostomy tube connector 1 and the tracheostomy tube body 2 can be further improved.

[0053] In some embodiments, two second flexible pressing portions 22 extend from one side of the limiting flange 23 toward the tracheostomy tube connector 1. Furthermore, a second snap-fit structure can be provided on the second flexible pressing portion 22. Therefore, by pressing the second flexible pressing portion 22, the second snap-fit structure can be easily disassembled from the first snap-fit structure.

[0054] In the above embodiments, the description of each embodiment has its own focus. For parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0055] The above is a description of the technical solution provided by the present invention. For those skilled in the art, according to the ideas of the embodiments of the present invention, there may be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
