Description

  The present invention relates to a one-touch connector for a tracheostomy tube, and more particularly to a connector for connecting an end of a tracheostomy tube and an end of another tube extended from a respirator circuit or the like.

  In general, a tracheostomy tube has a male terminal portion at one end portion to which a female terminal portion provided at an end portion of a tube of an artificial respirator circuit is connected (see, for example, Patent Document 1).

  Conventionally, in this type of tracheostomy tube, as shown in FIG. 6, the male terminal portion 21 is inserted into the female terminal portion 20 to be connected. That is, the male terminal portion 21 includes a cylindrical member 23 made of a synthetic resin fitted and held at an end portion of a tube main body 22 made of a rubber-like elastic body or a soft elastic body. The female terminal portion 20 is formed at an end portion of the tube body 24 made of synthetic resin, and is formed so as to be engageable with the tubular member 23 by taper shapes. Thus, when the male terminal portion 21 and the female terminal portion 20 are connected, the inner surface of the female terminal portion 20 is pressed against the outer surface of the tubular member 23 of the male terminal portion 21 and is firmly engaged. Yes.

  By the way, connection work and removal work of the artificial respiratory circuit tube to the tracheostomy tube need to be performed very quickly. However, if the connection between the male terminal portion 21 and the female terminal portion 20 is rushed, the connection state tends to be insufficient, and the male terminal portion 21 may be accidentally pulled out of the female terminal portion 20, or the female terminal portion 20 and the male terminal portion. There is a possibility that air leakage may occur from the connecting portion with the 21.

Further, in order to form a reliable connection state, it is preferable that the male terminal portion 21 is inserted into the female terminal portion 20 to a deeper depth to make a strong connection. The terminal portion 21 and the female terminal portion 20 are extremely difficult to come off. For this reason, when removing the male terminal portion 21 and the female terminal portion 20, it is necessary to strongly pull the male terminal portion 21 on the tube side of the artificial respirator circuit, and accordingly, the tracheostomy tube is also pulled. Pain may occur in patients with tracheostomy tubes. Moreover, since the female terminal part 20 and the patient's neck are close to each other in the tracheostomy tube main body attached to the patient, the grasping space on the tracheostomy tube main body side is extremely small, and the male terminal part 21 and the female When the terminal portion 20 is gripped and pulled, it is difficult to press the tracheostomy tube body side, so that the detaching operation is extremely difficult. Further, when the male terminal portion 21 and the female terminal portion 20 are removed, for example, a U-shaped removal tool (not shown) is interposed between the male terminal portion 21 and the female terminal portion 20 to fit the two. However, since the removal device is a separate body from the tracheostomy tube, it is easy to lose and handling is troublesome. For these reasons, there has been a disadvantage that the operation of removing the artificial respiratory circuit from the tracheostomy tube cannot be performed quickly.
JP 2003-93512 A (FIG. 1)

  An object of the present invention is to provide a one-touch connector for a tracheostomy tube that can eliminate the inconvenience and can firmly maintain the connection of the tracheostomy tube and can smoothly release the connection. To do.

  In order to achieve such an object, the present invention provides a one-touch for a tracheostomy tube that connects a male terminal provided at the distal end of the tracheostomy tube and a female terminal provided at the distal end of the breathing circuit side terminal. The male terminal portion includes a tapered outer peripheral engagement surface formed on an outer periphery thereof, and an annular convex portion protruding in a hook shape along a rear end edge of the outer peripheral engagement surface, The female terminal portion includes a tapered inner peripheral engagement surface that is formed on the inner periphery of the female terminal portion and that is press-engaged and engaged with the outer peripheral engagement surface. Further, on the outer periphery of the female terminal portion, a cylindrical outer cylinder formed of an elastic and flexible material is mounted.

  The outer cylindrical body is connected to a pair of first opposing wall portions facing each other via the female terminal portion with a predetermined distance from the female terminal portion, and the female terminals are connected to the female terminal portion. A pair of second opposing walls which are elastically bent and separated from the female terminal portion when the first opposing wall portions are opposed to each other via the female terminal portion in the vicinity of the portion and are pressed in a direction approaching each other. Department.

  Both the second opposing wall portions protrude on the inner surface side, and when the outer peripheral engagement surface is press-engaged with the inner peripheral engagement surface, they are locked to the rear side wall of the annular convex portion and both A locking claw for releasing the locking of the annular convex portion to the rear side wall when the second opposing wall portion is flexibly bent by the pressing operation of the first opposing wall portion is provided.

  In addition, the first opposing wall portions protrude from the inner surface side thereof, and come into contact with the front side wall of the annular convex portion by the pressing operation, so that the male terminal portion is pulled out through the annular convex portion. A pressing claw that presses and releases the engagement between the outer peripheral engagement surface and the inner peripheral engagement surface is provided.

  Furthermore, it is provided between the outer periphery of the female terminal portion and each of the first opposing wall portions so as to be detachable, and when inserted between the outer periphery of the female terminal portion and each of the first opposing wall portions, There is provided a regulating member that regulates the bending of the wall portion in the approaching direction and maintains the locking state of the locking claw to the annular convex portion.

  According to the connector of the present invention, when the male terminal portion is inserted into the female terminal portion, the inner peripheral engagement surface of the female terminal portion and the outer peripheral engagement surface of the male terminal portion are pressed and engaged. . Then, the male terminal portion is inserted deeply into the female terminal portion and connected in a sufficiently engaged state, and at the same time, the locking claws formed on the second opposing wall portion of the outer cylindrical body are connected to the male terminal portion. It is locked to the rear side wall of the annular projection. And even if both 1st opposing wall parts are carelessly pressed in the approach direction by inserting the said regulating member between the outer periphery of a female terminal part and each 1st opposing wall part, both 1st opposing Since the bending of the wall portion and both second opposing wall portions is restricted, the locking state of the locking claw to the annular convex portion is maintained, and the male terminal portion is reliably prevented from coming out of the female terminal portion. Therefore, a sufficient connection state can be maintained firmly.

  When the connection between the female terminal portion and the male terminal portion is released, the regulating member is detached from between the outer periphery of the female terminal portion and each first opposing wall portion, and both the first opposing wall portions approach each other. Press in the direction to do. Thereby, both the 2nd opposing wall part flexes in the direction which leaves | separates from a female terminal part elastically, and the latching to the rear side wall of the cyclic | annular convex part by a latching claw is cancelled | released. At the same time, both first opposing wall portions approach the female terminal portion by a pressing operation, and the pressing claw comes into contact with the front side wall of the annular convex portion. By the contact of the pressing claw at this time, the male terminal portion is pushed out by the pressing claw via the annular convex portion. As a result, the firm pressure engagement state between the outer peripheral engagement surface of the male terminal portion and the inner peripheral engagement surface of the female terminal portion is loosened, and the connection between the female terminal portion and the male terminal portion can be smoothly released. .

  Since the connection between the female terminal portion and the male terminal portion can be released only by pressing the first opposing wall portions, there is no need to strongly pull the male terminal portion on the other tube side, and the tracheostomy tube body The connection between the female terminal portion and the male terminal portion can be released with a light hand even if the side is not gripped or is gripped. Thereby, it is possible to release the connection between the female terminal portion and the male terminal portion without causing any trouble even if the grasping space on the tracheostomy tube main body side is extremely small without causing pain to the patient attached with the tracheostomy tube. . In addition, the connection between the female terminal portion and the male terminal portion can be released very easily without using a conventional U-shaped removal tool. As described above, according to the present invention, not only can a strong connection state between the male terminal portion and the female terminal portion be maintained and easy removal, but also the connection between the female terminal portion and the male terminal portion can be achieved. Release can be done quickly.

  Moreover, in this invention, it is preferable that the said outer cylinder body equips an inner periphery with the fitting part which fits rotatably in the groove part formed in the outer periphery whole periphery of the said female terminal part. Since the outer cylindrical body is rotatably provided on the outer periphery of the female terminal portion via the fitting portion, the outer cylindrical body can be rotated so that both the first opposing wall portions can be easily pressed. Thereby, the pressing operation of both the first opposing wall portions can be facilitated, and the connection between the male terminal portion and the female terminal portion can be smoothly released.

  Further, in the present invention, the restricting member is formed in a ring shape and is rotatably mounted on the outer periphery of the female terminal portion, and the outer periphery of the female terminal portion is opposed to each first end by rotation in one direction of the restricting member. A pair of restricting portions that are inserted between the wall portions so as to restrict bending of the first opposing wall portions in the approaching direction, and are connected to both restricting portions and are thinner than both restricting portions. And a restriction release portion that is formed between the outer periphery of the female terminal portion and each of the first opposing wall portions by being rotated in the other direction so that the first opposing wall portions can be flexed in the approaching direction. It is preferable to comprise.

  As a result, it is possible to restrict and release the bending of the first opposing wall portions simply by rotating the ring-shaped restricting member. That is, after the male terminal portion is inserted and connected to the female terminal portion, the restricting portion is placed between the outer periphery of the female terminal portion and each first opposing wall portion only by rotating the ring-shaped restricting member in one direction. Therefore, it is possible to quickly form a strong connection maintaining state between the male terminal portion and the female terminal portion. Further, when releasing the connection between the female terminal part and the male terminal part, prior to the pressing operation of each first facing wall part, the ring-shaped restricting member is simply rotated in the other direction so that the restriction releasing part is connected to the female terminal. It can be located between the outer periphery of a part and each 1st opposing wall part, and connection release with a female terminal part and a male terminal part can be performed rapidly.

  The one-touch connector for a tracheostomy tube according to the present invention can be similarly applied to a connector having a connector close to a human body, such as a gastrostomy tube button type or an artificial anus. In addition, when it has a female terminal part in the human body side, the structure which provided the cyclic | annular convex part in the female terminal side, and provided the said outer cylinder body and the said control member in the male terminal side is also employable.

  As shown in FIG. 1, the one-touch connector 1 for tracheostomy tube of the present embodiment connects a circuit tube B extended from the artificial respirator circuit to the tracheostomy tube A, and the distal end of the tracheostomy tube A And the female terminal portion 3 provided at the tip of the circuit tube B.

  As shown in FIGS. 1 and 4A, the male terminal portion 2 is rotatably provided at the distal end of a tracheostomy tube A formed of a rubber-like elastic body or a soft elastic body (for example, silicone rubber). A cylindrical member 4 made of synthetic resin is provided. The cylindrical member 4 includes an outer peripheral engagement surface 5 on the outer periphery thereof, and further includes an annular convex portion 6 protruding in a hook shape along the rear end edge of the outer peripheral engagement surface 5.

  As shown in FIG. 4A, the female terminal portion 3 includes an inner peripheral engagement surface 7 that is formed on a circuit tube B made of synthetic resin and press-engages with the outer peripheral engagement surface 5. .

  As shown in FIG. 1, an outer cylindrical body 9 made of a flexible and flexible synthetic resin is rotatably provided on the outer periphery of the female terminal portion 3. As shown in FIGS. 2 (a) and 4 (a), the outer cylindrical body 9 includes a pair of first opposing wall portions 10 facing each other, as shown in FIGS. 2 (a) and 5 (a). And a pair of second opposing wall portions 11 that face each other perpendicularly to the opposing direction of the first opposing wall portions 10, as shown in FIGS. 4 (a) and 5 (a), A fitting portion 13 is provided that protrudes inwardly and rotatably fits into a groove portion 12 formed on the entire outer periphery of the female terminal portion 3.

  As shown in FIG. 2 (b), the outer cylindrical body 9 presses the pair of first opposing wall portions 10 in a direction approaching each other, so that the pair of second opposing wall portions 11 are separated from each other. It is formed in a bent shape. Then, as shown in FIG. 4 (a), a pressing claw 14 having a triangular shape in cross section is provided on the inner side of each first opposing wall portion 10, and as shown in FIG. 5 (a), each second claw 14 is projected. A locking claw 15 having a triangular shape in cross section is provided on the inner side of the facing wall portion 11.

  As shown in FIG. 4A, the pressing claw 14 is provided at a position facing the front side wall of the annular convex portion 6 when the male terminal portion 2 and the female terminal portion 3 are connected. As shown in FIG. 5A, the locking claw 15 is provided so as to be locked to the rear side wall of the annular convex portion 6 when the male terminal portion 2 and the female terminal portion 3 are connected. .

  As shown in FIG. 1, the female terminal portion 3 is provided with a regulating member 16. As shown in FIG. 3, the regulating member 16 is formed in a ring shape and continuously includes a pair of regulating portions 17 formed to be thick and a regulation releasing portion 18 formed to be thin. Further, an operation convex portion 19 that protrudes in the outer peripheral direction is formed at the boundary between the restriction portion 17 and the restriction release portion 18. The restricting member 16 is rotatably supported by the female terminal portion 3 as shown in FIG. 2, and the restricting portion 17 is positioned inside the first opposing wall portion 10 as shown in FIG. When doing, the bending of the 1st opposing wall part 10 is controlled. As shown in FIG. 4B, when the restriction release portion 18 is located inside the first opposing wall portion 10, the restriction portion 17 is located on the second opposing wall portion 11 side as shown in FIG. Thus, the first opposing wall portion 10 can be bent freely.

  When the male terminal portion 2 and the female terminal portion 3 are connected, the operation convex portion 19 of the restriction member 16 is operated and rotated, and the restriction portion 17 is positioned on the second opposing wall portion 11 side as shown in FIG. . As a result, the first opposing wall portion 10 can be freely bent. Therefore, when the male terminal portion 2 is inserted into the female terminal portion 3 and the two are connected, the inner peripheral engagement surface 7 of the female terminal portion 3 is engaged with the outer periphery. The mating surface 5 is press-fitted and engaged. At this time, as shown in FIG. 5A, the locking claw 15 provided on the second opposing wall portion 11 of the outer cylindrical body 9 is elastically applied to the rear side wall of the annular convex portion 6 of the cylindrical member 4. Locked. Thereby, the male terminal portion 2 is prevented from coming off, and the connection state to the female terminal portion 3 is reliably maintained. Thereafter, the operation convex portion 19 of the restricting member 16 is operated and rotated, and the restricting portion 17 is positioned inside the first opposing wall portion 10 as shown in FIGS. 2 (a) and 4 (a). The bending of the 1st opposing wall part 10 is prevented. As a result, the male terminal portion 2 can be firmly retained and the connection state to the female terminal portion 3 can be more reliably maintained. Each restricting portion 17 is formed to have a wall thickness dimension that slightly presses both the first opposing wall portions 10 in a direction away from each other when positioned within the respective first opposing wall portions 10. Also good. According to this, each regulation part 17 bends in a direction in which both first opposing wall parts 10 are separated from each other, and accordingly, both second opposing wall parts 11 bend in a direction in which they approach each other. The locking claw 15 provided in the portion 11 can be locked deeper and firmly to the rear side wall of the annular convex portion 6 of the tubular member 4.

  Further, since the cylindrical member 4 of the male terminal portion 2 is rotatably provided with respect to the tracheostomy tube A, the inner peripheral engagement surface 7 of the female terminal portion 3 is the outer peripheral engagement surface 5 of the cylindrical member 4. The female terminal portion 3 can be rotated to a desired angle with respect to the male terminal portion 2 while being in press contact engagement with the male terminal portion 2. At this time, the locking claw 15 is formed on the annular convex portion 6 of the cylindrical member 4. Since the rear side wall is locked and the pressing claw 14 is separated from the annular convex portion 6, the female terminal portion 3 can be smoothly rotated with respect to the male terminal portion 2. Further, as described above, the outer cylindrical body 9 is rotatably provided on the entire outer periphery of the female terminal portion 3 via the fitting portion 13, so that both the first and second outer cylinders 9 are rotated. The facing wall 10 can be directed in a direction in which it can be easily pressed.

  When the connection between the male terminal portion 2 and the female terminal portion 3 is released, the operation convex portion 19 of the restriction member 16 is operated to restrict the state shown in FIG. 2A to the state shown in FIG. The member 16 is rotated. And as shown in FIG.2 (b), both the 1st opposing wall parts 10 of the outer cylinder 9 are pressed in the direction which mutually approaches. Thereby, both the 2nd opposing wall part 11 of the outer cylinder 9 bends outward, and the latching claw 15 leaves | separates from the rear side wall of the cyclic | annular convex part 6 of the cylindrical member 4 as shown in FIG.5 (b). . At the same time, by pressing both first opposing wall portions 10 of the outer cylindrical body 9, the pressing claw 14 comes into contact with the annular convex portion 6 of the cylindrical member 4 of the male terminal portion 2 as shown in FIG. Then push out the male terminal portion 2 in the pulling direction. As a result, the pressure contact engagement between the inner peripheral engagement surface 7 of the female terminal portion 3 and the outer peripheral engagement surface 5 of the cylindrical member 4 of the male terminal portion 2 is weakened, and the connection between the male terminal portion 2 and the female terminal portion 3 is reduced. Is easily released.

  As described above, according to the one-touch connector for tracheostomy tube 1 of the present embodiment, when the male terminal portion 2 is securely connected so as to be inserted into the female terminal portion 3, the locking claw 15 of the outer cylindrical body 9 is provided. Since the first opposing wall portion 10 is prevented from being bent by the restricting portion 17 of the restricting member 16 while being locked to the annular convex portion 6 of the tubular member 4, the male terminal portion 2 is pulled out from the female terminal portion 3. Thus, it is possible to maintain a connection state that is reliably prevented. Moreover, if the regulating member 16 is rotated so that the regulation releasing portion 18 is positioned in the first opposing wall portion 10, it is possible to press the first opposing wall portion 10 in a direction approaching each other, and the annular shape by the locking claw 15. At the same time that the locking to the convex portion 6 is released, the pressing claw 14 pushes out the male terminal portion 2 via the annular convex portion 6, so that the strong engagement state is loosened, and the female terminal portion 3 and the male terminal portion 2 are released. Can be smoothly disconnected. Since the connection between the female terminal portion 3 and the male terminal portion 2 can be released by pressing the first opposing wall portions 10 in this way, it is not necessary to pull the male terminal portion 2 on the circuit tube B side strongly. The circuit tube B can be removed from the tracheostomy tube A with almost no resistance. Furthermore, since the circuit tube B can be removed without touching the main body side of the tracheostomy tube A, or with a light hand even if it is gripped, there is no pain to the patient, and the tracheostomy tube A main body side can be removed. Even if the gripping space is extremely small, the circuit tube B can be removed without hindrance. Further, not only can the rotation operation of the restricting member 16 and the pressing operation of the first opposing wall portions 10 be performed with one hand, but extremely without using a conventional U-shaped detachment device (not shown). The tube B can be easily removed. As described above, according to the present embodiment, the tracheostomy tube A and the circuit tube B can be securely and firmly connected, and the circuit tube B is removed from the tracheostomy tube A with both first opposing walls. It can be performed smoothly and quickly only by pressing the portion 10.
