Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a tracheotomy tube. Background Art

[0002] During the use of a tracheotomy tube, a patient may have secretions, such as phlegm. If a completely closed tracheotomy tube is used, the secretions are likely to block inside the tube, resulting in a reduction in the amount of gas that can be absorbed by the patient, affecting the use effect of the tracheotomy tube and causing adverse effects on the patient. Therefore, when using a tracheotomy tube, it is necessary to drain the patient's secretions.

[0003] In the related art, there is a tracheotomy tube connector with openings on the side, which is connected to the interface of the tracheotomy tube body. When the patient has secretions, the secretions can be led to the connector and then drained from the openings on the side of the connector. In addition, the tracheotomy tube body and the tracheotomy tube connector are connected by a buckle to limit axial displacement, and the pressing area is set on the tracheotomy tube connector. Therefore, when disassembling the tracheotomy tube body and the tracheotomy tube connector, it is necessary to first press the pressing areas on both sides of the tracheotomy tube connector, then drive the force-receiving areas on both sides of the tracheotomy tube body to move towards each other and deform, and finally cause the buckle position to loosen, so as to achieve the separation of the tracheotomy tube body and the tracheotomy tube connector. However, since the tracheotomy tube body is indirectly deformed by force and the buckle position needs to be loosened, during the pressing process, the external force needs to be large enough to finally achieve disassembly, and the entire separation process is rather cumbersome and not convenient and fast. Summary of the Utility Model

[0008] Furthermore, a side of the pressing portion facing away from the tracheotomy tube connector is provided with anti-slip textures.

[0009] Furthermore, the first flange extends along the circumferential direction of the tracheotomy tube body, and two protruding blocks are protruded from one side of the first flange close to the first direction, and the two protruding blocks are arranged at a preset interval.

[0010] Furthermore, the tracheotomy tube body further protrudes with a second flange, the second flange extends along the circumference of the tracheotomy tube body, and the tracheotomy tube joint includes an end wall, the end wall abuts against the second flange close to the second direction side.

[0011] Further, a flow guiding structure is provided at one end of the tracheostomy tube connector away from the end wall. A first opening is formed on the side of the flow guiding structure away from the end wall, and the first opening communicates with the inside of the tracheostomy tube connector and the outside.

[0012] Further, the tracheostomy tube connector includes a straight portion and a bent portion. The straight portion is connected to the bent portion, and the end wall is provided at one end of the straight portion away from the bent portion; the inner side wall of the bent portion forms the flow guiding structure, and the first opening is located on the side of the bent portion away from the straight portion.

[0013] Further, the first opening is inclined with respect to the straight portion, and there is an angular relationship of n° between the plane where the first opening is located and the straight portion, 90 < n < 180.

Therefore, it is convenient for the user to perform the pressing operation, and too much force does not need to be applied during pressing, which can reduce the difficulty of detachable separation.

In the description of the present utility model, "a plurality of" means two or more, unless otherwise specifically defined.

[0028] Please refer to Figures 1-4 , an embodiment of the present utility model provides a tracheostomy tube, including a tracheostomy tube body 1 and a tracheostomy tube joint 2; a part of the tracheostomy tube body 1 is inserted into the tracheostomy tube joint 2, and the tracheostomy tube body 1 and the tracheostomy tube joint 2 are in abutment to limit the axial displacement of the tracheostomy tube joint 2 relative to the tracheostomy tube body 1 and along a first direction; a first abutting structure is provided at one end of the tracheostomy tube body 1 close to the tracheostomy tube joint 2, and a pressing structure 21 protrudes from the outer side wall of the tracheostomy tube joint 2, and a second abutting structure is provided on the pressing structure 21; the pressing structure 21 is movably connected to the tracheostomy tube joint 2 to enable the second abutting structure to switch from a first position to a second position; when the second abutting structure is in the first position, the first abutting structure is connected to the second abutting structure to limit the axial displacement of the tracheostomy tube joint 2 relative to the tracheostomy tube body 1 and along a second direction; and the first direction and the second direction are opposite directions; when the second abutting structure is in the second position, the first abutting structure is separated from the second abutting structure.

[0029] In the embodiment of the present utility model, when the tracheotomy tube body 1 is connected to the tracheotomy tube joint 2, a part of the tracheotomy tube body 1 penetrates through the tracheotomy tube joint 2, and the tracheotomy tube body 1 and the tracheotomy tube joint 2 are in abutment, so that the tracheotomy tube joint 2 cannot perform axial displacement relative to the tracheotomy tube body 1 and along the first direction. In addition, the tracheotomy tube body 1 is provided with a first abutting structure, the tracheotomy tube joint 2 is provided with a pressing structure 21, and the pressing structure 21 is provided with a second abutting structure. The pressing structure 21 is movably connected to the tracheotomy tube joint 2. Therefore, by means of the pressing structure 21, the position of the second abutting structure in the tracheotomy tube joint 2 can be changed, so that the first abutting structure and the second abutting structure are connected or separated, thereby realizing the detachable connection between the tracheotomy tube joint 2 and the tracheotomy tube body 1.

[0030] When the second abutting structure is in the first position, the first abutting structure and the second abutting structure are connected, and the tracheotomy tube joint 2 cannot perform axial displacement relative to the tracheotomy tube body 1 and along the second direction, thereby realizing the axial limit between the tracheotomy tube body 1 and the tracheotomy tube joint 2. When the pressing structure 21 is pressed so that the second abutting structure switches from the first position to the second position, the first abutting structure and the second abutting structure are separated, so that the tracheotomy tube body 1 and the tracheotomy tube joint 2 can perform axial displacement along the second direction, and the disassembly and separation between the tracheotomy tube body 1 and the tracheotomy tube joint 2 can be realized.

[0031] In the embodiment of the present utility model, only by pressing the pressing structure 21 can the disassembly and separation be realized, without deforming the tracheotomy tube body 1 through the tracheotomy tube joint 2, and there is no snap structure, and the pressing structure 21 protrudes from the outer side wall of the tracheotomy tube joint 2. Therefore, it is convenient for the user to perform the pressing operation, and too much force does not need to be applied during pressing, which can reduce the difficulty of disassembly and separation.

[0032] It can be understood that if the axial direction is divided into the up and down directions, if the first direction is the upward direction, then the second direction is the downward direction. If the first direction is the downward direction, then the second direction is the upward direction.

[0033] Further, two first abutting structures are symmetrically arranged at one end of the tracheotomy tube body 1 close to the tracheotomy tube joint 2, two symmetric pressing structures 21 protrude from the outer side wall of the tracheotomy tube joint 2, and both of the two pressing structures 21 are provided with second abutting structures. The first abutting structures and the second abutting structures correspond one by one, and the corresponding first positions of different second abutting structures are different, and the corresponding second positions of different second abutting structures are different.

[0034] Specifically, along the axis of the tracheotomy tube, two first abutting structures are symmetrically arranged on both sides of the tracheotomy tube body 1; two pressing structures 21 are symmetrically arranged on both sides of the tracheotomy tube joint 2, and two symmetric second abutting structures are arranged on the two pressing structures 21. One of the first abutting structures corresponds to one of the second abutting structures, which can realize the axial limit of the tracheotomy tube joint 2 relative to the tracheotomy tube body 1 and along the second direction. The other first abutting structure corresponds to the other second abutting structure, which can also realize the axial limit of the tracheotomy tube joint 2 relative to the tracheotomy tube body 1 and along the second direction.

[0035] First, two pressing structures 21 are symmetrically arranged. During actual use, after the tracheotomy tube body 1 and the tracheotomy tube joint 2 are connected, when one of the pressing structures 21 is pressed, the second abutting structure of the other pressing structure 21 is still connected to the corresponding first abutting structure, and the tracheotomy tube body 1 and the tracheotomy tube joint 2 are still in an axially limited connection relationship. Only when both pressing structures 21 are pressed simultaneously can the separation and disassembly of the tracheotomy tube body 1 and the tracheotomy tube joint 2 be realized, which can effectively prevent accidental disassembly.

[0036] Second, two first abutting structures are symmetrically arranged, and two second abutting structures are symmetrically arranged. Therefore, when the first abutting structure and the second abutting structure are correspondingly connected, the tracheotomy tube joint 2 and the tracheotomy tube body 1 can be in force balance, realizing connection stability.

[0037] Furthermore, two pressing structures 21 are symmetrically arranged, and the pressing structures 21 protrude from the outer side wall of the tracheotomy tube joint 2, so that the relative distance between the two pressing structures 21 can be increased. Compared with the technical solution in the related art where the relative distance between the pressing structures 21 on both sides of the tracheotomy tube joint 2 is relatively short, the two pressing structures 21 in the embodiment of the present utility model can, to a certain extent, reduce the acting force applied to the pressing structures 21 and further reduce the difficulty of disassembly and separation.

[0038] Further, the first abutting structure includes a first flange 11 protruding from the outer side wall of the tracheotomy tube body 1. The pressing structure 21 includes an abutting portion 211, a fulcrum portion 212, and a pressing portion 213. The second abutting structure includes the abutting portion 211. The fulcrum portion 212 protrudes from the outer side wall of the tracheotomy tube joint 2. The abutting portion 211 and the pressing portion 213 are connected to the side of the fulcrum portion 212 away from the tracheotomy tube joint 2. The abutting portion 211 abuts against the side of the first flange 11 close to the first direction. The pressing portion 213 is arranged on the side of the fulcrum portion 212 away from the abutting portion 211. The abutting portion 211 has elasticity and is used to provide a restoring force for moving the abutting portion 211 towards the direction close to the first flange 11.

[0039] Specifically, on the outer sidewall of the tracheotomy tube body 1, a first flange 11 protrudes. On the outer sidewall of the tracheotomy tube connector 2, a fulcrum portion 212 protrudes, and at the top of the fulcrum portion 212, a lever is connected. On both sides of the fulcrum portion 212, the lever is respectively a pressing portion 213 and an abutting portion 211. The fulcrum portion 212 can raise the distance between the lever and the tracheotomy tube connector 2, reducing the difficulty of pressing.

[0040] In the initial state, that is, when the tracheotomy tube body 1 and the tracheotomy tube connector 2 are connected, the abutting portion 211 abuts against one side of the first flange 11 close to the first direction, so as to realize the axial limit of the tracheotomy tube connector 2 relative to the tracheotomy tube body 1 and along the second direction. When pressing the pressing portion 213, with the fulcrum portion 212 as the fulcrum, the pressing portion 213 moves towards the side close to the tracheotomy tube connector 2, then the abutting portion 211 moves away from the tracheotomy tube connector 2, and the abutting portion 211 can move away from the first flange 11, so as to realize the separation of the first abutting structure and the second abutting structure, and further realize the disassembly and separation of the tracheotomy tube body 1 and the tracheotomy tube connector 2.

[0041] In addition, the abutting portion 211 is an elastic structure. Therefore, when the tracheotomy tube body 1 and the tracheotomy tube connector 2 are connected, when no force is applied to the pressing portion 213, the abutting portion 211 will automatically reset, and the abutting portion 211 will move towards the direction close to the first flange 11, and finally the abutting portion 211 abuts against the first flange 11.

[0042] Furthermore, in some embodiments, along the axis of the tracheotomy tube, two first flanges 11 are symmetrically arranged on both sides of the tracheotomy tube body 1. The first flange 11 extends along the axial direction of the tracheotomy tube body 1. Therefore, in some realizable ways, the two first flanges 11 can be integrated to form an annular structure; in some realizable ways, the two first flanges 11 can be separated and present two symmetrical arc-shaped structures.

[0043] In addition, along the axis of the tracheotomy tube, two pressing structures 21 are symmetrically arranged on both sides of the tracheotomy tube connector 2, and the two pressing structures 21 are provided with two symmetrical abutting portions 211 and two pressing portions 213. The two pressing structures 21 are separated and arranged at intervals on both sides of the tracheotomy tube connector 2. Therefore, only by pressing the two pressing structures 21 simultaneously can the separation of the first abutting structure and the second abutting structure be realized to achieve the disassembly and separation of the tracheotomy tube body 1 and the tracheotomy tube connector 2. Moreover, when two pressing structures 21 are symmetrically arranged on both sides of the tracheotomy tube connector 2, the fulcrum portion 212 can raise the distance between the corresponding lever and the tracheotomy tube connector 2, and the two symmetrical fulcrum portions 212 can increase the relative distance between the two levers, so as to reduce the force applied to the pressing structure 21 to a certain extent and further reduce the difficulty of disassembly and separation.

[0044] Further, an anti-slip texture is provided on the side of the pressing portion 213 facing away from the tracheotomy tube connector 2. By providing the anti-slip texture on the pressing portion 213, it is beneficial for the user to press the pressing portion 213, thereby further facilitating the user to disassemble.

[0045] Further, the first flange 11 extends along the circumferential direction of the tracheotomy tube body 1, and two protruding blocks 13 protrude from the side of the first flange 11 close to the first direction. The two protruding blocks 13 are arranged at a preset interval.

[0046] Specifically, on the side where the abutting portion 211 abuts against the first flange 11, two protruding blocks 13 also protrude from the first flange 11. Therefore, when the tracheotomy tube body 1 and the tracheotomy tube connector 2 rotate relative to each other in the circumferential direction, the moving displacement of the abutting portion 211 along the circumferential direction of the tracheotomy tube on the first flange 11 is limited. During the process of driving the tracheotomy tube connector 2 to rotate relative to the tracheotomy tube body 1 in a certain direction, when the side wall of the abutting portion 211 abuts against one of the protruding blocks 13, due to the action of the side wall of the abutting portion 211 and the protruding block 13, the tracheotomy tube connector 2 cannot rotate in this direction anymore, so that the tracheotomy tube connector 2 and the tracheotomy tube body 1 cannot rotate relative to each other anymore. Therefore, by limiting the interval distance between the two protruding blocks 13 in the circumferential direction, the rotational freedom of the tracheotomy tube connector 2 and the tracheotomy tube body 1 can be limited, so that the tracheotomy tube connector 2 and the tracheotomy tube body 1 cannot rotate 360°. Therefore, when discharging secretions, the angle can be quickly adjusted, so as to quickly discharge the secretions.

[0047] In some embodiments, along the axis of the tracheotomy tube, two first flanges 11 are symmetrically arranged on both sides of the tracheotomy tube body 1. In some realizable ways, two protruding blocks 13 can be provided on one of the first flanges 11, and no protruding blocks 13 are provided on the other first flange 11. In some other realizable ways, two protruding blocks 13 are respectively provided on both first flanges 11, where two protruding blocks 13 correspond to one of the abutting portions 211, and the other two protruding blocks 13 correspond to the other abutting portion 211. And the two protruding blocks 13 of one flange and the two protruding blocks 13 of the other flange are symmetrically arranged.

[0048] It should be noted that in the actual process, the interval between the two protruding blocks 13 of the same first flange 11 is set according to actual needs, that is, the present invention does not make specific limitations on the preset interval.

[0049] Further, a second flange 12 also protrudes from the tracheotomy tube body 1. The second flange 12 extends along the circumferential direction of the tracheotomy tube body 1. The tracheotomy tube connector 2 includes an end wall 22, and the end wall 22 abuts against the side of the second flange 12 close to the second direction.

[0050] Specifically, the second flange 12 protrudes from the outer wall of the tracheotomy tube body 1, and the end wall 22 is the wall surface at the end of the tracheotomy tube joint 2. The tracheotomy tube joint 2 is connected to the tracheotomy tube body 1, and a part of the tracheotomy tube body 1 is inserted into the tracheotomy tube joint 2. The end wall 22 abuts against the second flange 12, so that the axial limit of the tracheotomy tube joint 2 relative to the tracheotomy tube body 1 along the first direction can be realized. Cooperating with the first limit structure and the second limit structure, the axial limit of the tracheotomy tube joint 2 and the tracheotomy tube body 1 is realized.

[0051] In some embodiments, the second flange 12 can extend circumferentially along the tracheotomy tube to form an annular shape, and the end wall 22 of the tracheotomy tube joint 2 is also annular. When the two abut, the force-bearing area increases, and the connection stability between the two can be improved. In addition, when two first limit structures are symmetrically arranged and two second limit structures are symmetrically arranged, the annular second flange 12 and the end wall 22 can better realize the axial limit of the tracheotomy tube joint 2 and the tracheotomy tube body 1 when cooperating with the first limit structure and the second limit structure.

[0052] In some embodiments, the second flange 12 is arc-shaped. In one implementable manner, only one second flange 12 is provided. In another implementable manner, corresponding to the two first limit structures, two arc-shaped second flanges 12 are symmetrically arranged. Similarly, when two first limit structures are symmetrically arranged and two second limit structures are symmetrically arranged, the axial limit of the tracheotomy tube joint 2 and the tracheotomy tube body 1 can be better realized when cooperating with the first limit structure and the second limit structure.

[0053] Furthermore, a flow guiding structure 23 is provided at one end of the tracheotomy tube joint 2 away from the end wall 22. A first opening 24 is formed on the side of the flow guiding structure 23 away from the end wall 22, and the first opening 24 communicates with the inside of the tracheotomy tube joint 2 and the outside.

[0054] Specifically, a flow guiding structure 23 is provided at one end of the tracheotomy tube joint 2 away from the tracheotomy tube body 1. When the tracheotomy tube joint 2 is connected to the tracheotomy tube body 1, the secretions flowing out of the tracheotomy tube body 1 will flow into the inside of the tracheotomy tube joint 2. Since the flow guiding structure 23 is provided and the first opening 24 is formed on the side of the flow guiding structure 23 away from the end wall 22, under the guiding action of the flow guiding structure 23, the secretions flowing into the inside of the tracheotomy tube joint 2 can be collected in the flow guiding structure 23 and flow out to the outside from the first opening 24 in a concentrated manner, which can effectively prevent the secretions from contacting medical staff, etc., and is safe and reliable.

[0055] Furthermore, the tracheotomy tube joint 2 includes a straight portion and a bent portion. The straight portion is connected to the bent portion, and the end wall 22 is provided at one end of the straight portion away from the bent portion; the inner side wall of the bent portion forms the flow guiding structure 23, and the first opening 24 is located on the side of the bent portion away from the straight portion.

[0056] Specifically, the tracheotomy tube connector 2 includes two parts, a straight part and a bent part. The bent part is formed by bending, and there is a certain angular relationship between the extending direction of the bent part and the extending direction of the straight part. The diversion structure 23 is formed by the inner side wall formed by bending the bent part, and the first opening 24 is located on the side of the bent part away from the straight part. When the tracheotomy tube connector 2 and the tracheotomy tube body 1 are connected, the secretions flowing out from the tracheotomy tube body 1 will flow to the inner side wall of the straight part of the tracheotomy tube and then to the inner side wall of the bent part. Due to the guiding effect of the inner side wall of the bent part, the secretions can flow out to the outside from the first opening 24 concentratedly, which can effectively prevent the secretions from contacting medical staff, etc., and is safe and reliable.

[0057] Furthermore, the first opening 24 is inclined with respect to the straight part, and there is an angular relationship of n° between the plane where the first opening 24 is located and the straight part, where 90 < n < 180.

[0058] Specifically, the first opening 24 is arranged on the side of the bent part away from the straight part, and the angle between the first opening 24 and the straight part can be 91°, 100°, 110°, 120°, 130°, 140°, 150°, 160° or 170°, etc. The first opening 24 of the bent part is inclined with respect to the straight part. Therefore, when the secretions flow to the first opening 24, they will be blocked by the inner side wall near the first opening 24 in the bent part. Thus, the secretions can flow out to the outside from the first opening 24 concentratedly, which can effectively prevent the secretions from contacting medical staff, etc., and is safe and reliable.

[0059] Furthermore, a second opening 25 communicating the inside and the outside is provided on the side wall of the tracheotomy tube connector 2.

[0060] Specifically, the second opening 25 can be arranged on the side wall of the bent part, can also be arranged on the side wall of the straight part, or can also be arranged on the side wall at the connection position of the bent part and the straight part, and the shape of the second opening 25 is not specifically limited in the embodiments of the present invention. The second opening 25 can be suitable for different postures of the patient. For example, when the patient lies flat or on the side, the secretions in the tracheotomy tube can be conveniently discharged from the second opening 25.

[0061] In the above embodiments, the descriptions of each embodiment have their own emphases. For the parts not detailed in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0062] The above is the description of the technical solutions provided by the present invention. For those skilled in the art, according to the idea of the embodiments of the present invention, there will be changes in the specific implementation manners and application scopes. In summary, the content of this specification should not be construed as a limitation to the present invention.
