Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to a connector for a metal tracheotomy cannula. Background Technology

[0002] The content in this section only provides background information related to this utility model and may not constitute prior art.

[0003] In clinical practice, metal tracheostomy tubes are widely used for patients who require long-term indwelling tracheostomy tubes due to their ease of use and maintenance.

[0004] However, because the inner cannula of such cannulas is typically made of a single, smooth metal tube, the portion of the inner cannula extending beyond the outer cannula also has a smooth metal surface. This design has certain drawbacks in clinical applications: due to the lack of a fitting or fixing structure at the cannula opening, it is difficult to securely attach an artificial nose (also known as a "disposable heat and moisture exchanger," an auxiliary respiratory device used to keep inhaled air warm and moist), thus limiting the possibility of improving the patient's breathing comfort through an artificial nose.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments. The same reference numerals in the accompanying drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] Compared to the embodiments shown in the accompanying drawings, feasible embodiments within the scope of protection of this utility model may have fewer components, have other components not shown in the drawings, different components, components arranged differently, or components with different connections, etc. Furthermore, two or more components shown in the drawings may be implemented in a single component, or a single component shown in the drawings may be implemented as multiple separate components.

[0021] An embodiment of this utility model discloses a connector 10, and more particularly a connector 10 for connecting a metal tracheotomy cannula 20 and an artificial nose 30.

[0022] To facilitate the explanation of the connector 10 disclosed in the embodiments of this utility model, the necessary structures of the metal tracheotomy sleeve 20 and the artificial nose 30 will be briefly described below.

[0023] like Figure 1 As shown, a known metal tracheostomy tube 20 typically includes an outer tube 21 and an inner tube 22. In use, one end of the inner tube 22 extends into the outer tube 21 through an opening at the limiting portion 211 of the outer tube 21, while the other end of the inner tube 22 serves as a tube opening 23 and is exposed outside the outer tube 21.

[0024] like Figure 2As shown, a known artificial nose 30 typically includes a ventilation section 31 and an air duct 32 extending from the ventilation section 31. When a person inhales, external air first enters the ventilation section 31 to humidify and warm the incoming air. Subsequently, the humidified and warmed air flows out through the air duct 32 and enters the human body to improve inhalation comfort. When a person exhales, the exhaled air passes through the air duct 32 to the ventilation section 31, where the ventilation section 31 retains the moisture and temperature of this portion of the air, thereby humidifying and warming the air inhaled during subsequent inhalations.

[0025] As can be seen, to achieve a reliable connection between the metal tracheostomy tube 20 and the artificial nose 30, it is only necessary to reliably connect the tube opening 23 to the airway 32.

[0026] Figure 3 This is a schematic diagram of the connector 10 disclosed in the embodiment of the present utility model. In order to achieve a reliable connection between the port 23 and the air guide tube 32, the connector 10 disclosed in the embodiment of the present utility model may include a tubular body 11, a first locking member 12 and a second locking member 13.

[0027] Combination Figures 4 to 6 As shown, the tubular body 11 includes a first connecting portion 111 and a second connecting portion 112 coaxially connected along the axial direction of the tubular body 11. The first connecting portion 111 defines a first connecting channel 113, and the second connecting portion 112 defines a second connecting channel 114. The first connecting channel 113 and the second connecting channel 114 extend in opposite directions along the axial direction of the tubular body 11 and respectively penetrate the first connecting portion 111 and the second connecting portion 112.

[0028] The first connecting channel 113 and the second connecting channel 114 are connected to each other. Furthermore, the first connecting channel 113 is adapted to the port 23, and the second connecting channel 114 is adapted to the air guide tube 32.

[0029] In this embodiment, the adaptation of the first connecting channel 113 to the port 23 can mean that the inner diameter of the first connecting channel 113 is the same as the outer diameter of the port 23, so that the free end of the port 23 can extend into the first connecting channel 113 through the open end of the first connecting channel 113, and the outer wall of the port 23 can be tightly fitted with the inner wall of the first connecting channel 113. Correspondingly, the adaptation of the second connecting channel 114 to the air guide tube 32 can mean that the inner diameter of the second connecting channel 114 is the same as the outer diameter of the air guide tube 32, so that the free end of the air guide tube 32 can extend into the second connecting channel 114 through the open end of the second connecting channel 114, and the outer wall of the air guide tube 32 can be tightly fitted with the inner wall of the second connecting channel 114.

[0030] Reference Figure 4As shown, the first locking member 12 is threaded to the first connecting portion 111, allowing it to rotate axially along the tubular body 11. The first locking member 12 internally defines a first insertion channel 121 extending axially along the tubular body 11 and penetrating the first locking member 12 (see...). Figure 7 The first insertion channel 121 is connected to the first connection channel 113. The inner wall of the first insertion channel 121 is provided with a first locking slope 122 in an annular shape.

[0031] Continue to refer to Figure 4 As shown, the second locking member 13 is threaded to the second connecting portion 112, allowing it to rotate axially along the tubular body 11. The second locking member 13 internally defines a second insertion channel 131 extending axially along the tubular body 11 and penetrating the second locking member 13 (see...). Figure 8 The second insertion channel 131 is connected to the second connection channel 114. The inner wall of the second insertion channel 131 is provided with a second locking bevel 132 in an annular shape.

[0032] At the same time, such as Figure 5 and Figure 6 As shown, the tubular body 11 also includes a plurality of first locking portions 115 and a plurality of second locking portions 116. The plurality of first locking portions 115 and the plurality of second locking portions 116 can all be made of elastic materials such as elastic plastic, so that each first locking portion 115 and each second locking portion 116 has elastic deformation capability. The plurality of first locking portions 115 are sequentially spaced along the circumference of the first connecting channel 113 at the open end of the first connecting channel 113 to form a first locking channel 117 through which the pipe opening 23 passes. Each first locking portion 115 extends axially away from the first connecting portion 111 along the tubular body 11, and the outer wall of the end of each first locking portion 115 away from the first connecting channel 113 is provided with a third locking slope 118 that cooperates with the first locking slope 122.

[0033] Multiple second locking portions 116 are sequentially spaced along the circumference of the second connecting channel 114 at the open end of the second connecting channel 114 to form a second locking channel 119 through which the air guide tube 32 passes. Each second locking portion 116 extends axially away from the second connecting portion 112 along the tubular body 11, and the outer wall of the end of each second locking portion 116 away from the second connecting channel 114 is provided with a fourth locking slope 101 that cooperates with the second locking slope 132.

[0034] Based on the above configuration, when actually using the connector 10, it can first be connected to one of the port 23 of the metal tracheostomy sleeve 20 and the airway 32 of the artificial nose 30. Then, the other of the port 23 and airway 32 can be connected to the connector 10, thus achieving the connection between the port 23 and the airway 32. (See...) Figure 9 For ease of explanation, the embodiment of this utility model is illustrated by first connecting the connector 10 to the port 23 and then connecting the air duct 32 to the connector 10.

[0035] Reference Figure 10 As shown, when it is necessary to connect the connector 10 to the port 23, the free end of the port 23 is first inserted into the first insertion channel 121 through the open end of the first locking member 12 until the free end of the port 23 passes through the first locking channel 117 formed by the multiple first locking parts 115 and extends into the first connecting channel 113. Then, by operating the first locking member 12 to rotate, the first locking member 12 moves along the axial direction of the tubular body 11 towards the direction of the second connecting part 112. At this time, the first locking ramp 122 on the first locking member 12 will move relative to the third locking ramp 118 on each of the first locking parts 115. The ends of the multiple first locking parts 115 away from the first connecting channel 113 will synchronously move towards the axial direction of the tubular body 11, thereby clamping the port 23 passing through the multiple first locking parts 115. This achieves the purpose of temporarily connecting the connector 10 to the port 23. Conversely, simply rotating the first locking member 12 in the opposite direction will cause the ends of the multiple first locking parts 115 away from the first connecting channel 113 to open synchronously in a direction away from the axis of the tubular body 11, thereby releasing the clamping on the tube opening 23. The operation is simple and convenient.

[0036] After connector 10 is connected to port 23, air guide tube 32 can be connected to connector 10. The process of connecting air guide tube 32 to connector 10 is basically the same as the process described above. Specifically, the free end of air guide tube 32 is first inserted into the second insertion channel 131 through the open end of the second insertion channel 131 of the second locking member 13, until the free end of air guide tube 32 passes through the second locking channel 119 formed by the enclosing of multiple second locking parts 116 and extends into the second connecting channel 114. Subsequently, by rotating the second locking member 13, it moves along the axial direction of the tubular body 11 towards the first connecting portion 111. At this time, the second locking ramp 132 on the second locking member 13 moves relative to the fourth locking ramp 101 on each of the second locking portions 116. The ends of the multiple second locking portions 116 away from the second connecting channel 114 move synchronously towards the axis of the tubular body 11, thereby clamping the air guide tube 32 passing through the multiple second locking portions 116. This achieves the purpose of temporarily connecting the air guide tube 32 to the connector 10. Conversely, by simply rotating the second locking member 13 in the opposite direction, the ends of the multiple second locking portions 116 away from the second connecting channel 114 open synchronously in a direction away from the axis of the tubular body 11, thus releasing the clamping of the air guide tube 32. The operation is simple and convenient.

[0037] As can be seen, the connector 10 disclosed in this embodiment of the present invention, by setting a connection channel that adapts to the opening 23 of the metal tracheostomy sleeve 20 and the air duct 32 of the artificial nose 30, and in conjunction with the threaded locking member and the elastic locking part, can quickly and stably achieve a reliable connection between the opening 23 and the air duct 32 without changing the existing structure of the metal tracheostomy sleeve 20 and the artificial nose 30, thereby providing a feasible and convenient solution for fitting the artificial nose 30 onto the metal tracheostomy sleeve 20.

[0038] In some embodiments, each of the first locking portions 115 is provided with a first anti-slip structure (not shown in the figure) facing the inner wall of the first locking channel 117. The first anti-slip structure can be an anti-slip protrusion or anti-slip texture, etc. The provision of the first anti-slip structure helps to increase the friction between the tube opening 23 and each of the first locking portions 115, thereby improving the clamping effect.

[0039] In some embodiments, each of the second locking portions 116 is provided with a second anti-slip structure (not shown in the figure) facing the inner wall of the second locking channel 119. The second anti-slip structure can be an anti-slip protrusion or anti-slip texture, etc. The provision of the second anti-slip structure helps to increase the friction between the air guide tube 32 and each of the second locking portions 116, thereby improving the clamping effect.

[0040] In some embodiments, refer to Figure 4The tubular body 11 has an annular seal 14 located between the first connecting channel 113 and the second connecting channel 114. The end of the pipe opening 23 extending into the first connecting channel 113 and the end of the air guide tube 32 extending into the second connecting channel 114 both abut against the annular seal 14. Figure 10 .

[0041] The annular seal 14 helps improve the sealing between the port 23 and the connector 10, and between the air duct 32 and the connector 10. Furthermore, the annular seal 14 helps reduce the manufacturing and usage costs of the connector 10. The annular seal 14 can be a rubber sealing ring.

[0042] In some embodiments, the spacing between two adjacent first locking parts 115 is equal, so as to make the clamping force of the multiple first locking parts 115 acting on the nozzle 23 as evenly distributed as possible, thereby helping to improve the clamping effect.

[0043] In some embodiments, the spacing between two adjacent second locking parts 116 may also be equal, so as to make the clamping force of the multiple second locking parts 116 acting on the air guide tube 32 as evenly distributed as possible, thereby helping to improve the clamping effect.

[0044] In some embodiments, the outer wall of the first locking member 12 is provided with at least a pair of symmetrically distributed first operating surfaces 123, and the first operating surfaces 123 are planar, see Figure 3 This facilitates the rotation of the first locking element 12.

[0045] In some embodiments, the outer wall of the second locking member 13 is provided with at least a pair of symmetrically distributed second operating surfaces 133, and the second operating surfaces 133 are planar, see Figure 3 This facilitates the rotation of the second locking element 13.

[0046] In some embodiments, such as Figure 4 As shown, the tubular body 11 may further include a handle 102 disposed between the first connecting portion 111 and the second connecting portion 112. The handle 102 protrudes outward along the radial direction of the tubular body 11. The handle 102 facilitates the user's operation of the first locking member 12 and / or the second locking member 13 while holding the handle 102, thus improving the convenience of using the connector 10.

[0047] In some embodiments, the first connecting part 111, the second connecting part 112, the plurality of first locking parts 115, the plurality of second locking parts 116, and the handle part 102 may be an integral structure to simplify the processing and manufacturing process of the tubular body 11 as much as possible.

[0048] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
