Detailed Description
Example 1: the application of the drainage tube adaptive joint is shown in fig. 1, which is intended to adapt to the connection needs of any diameter of an intracorporeal drainage tube 1. As can be seen from the figure, one end of the drainage tube 1 led out of the body extends into the abdominal cavity as a drainage end, and the other end is connected with the self-adaptive joint. One end of the bag tube 2 is connected with the drainage bag 4, and the other end is connected with the self-adaptive joint.
The specific structure of the drainage tube adaptive joint 3 is shown in fig. 2-4 respectively. One end of the drainage tube self-adaptive joint 3 is fixedly connected with the bag tube 2, the other end is in sealed sleeve joint with the drainage tube 1 led out from the body, as can be seen from figures 3 and 4, an annular air bag 8 is fixed in the inner cavity of the sleeve joint part, an air tap 9 is arranged on the outer side of the sleeve joint part, and a one-way valve is arranged in the air tap 9 and communicated with the annular air bag 8. Therefore, when the internal drainage tube 1 is inserted into the annular air bag 8 and the air bag is inflated, the annular air bag is expanded and sealed and sleeved between the inner wall of the joint and the outer wall of the internal drainage tube 1.
In this embodiment, the design of the self-adaptive joint 3 includes a large diameter section 6 and a small diameter section 12, between which is a tapered section 11, and the annular balloon 8 is located inside the large diameter section 6. Wherein the large diameter section 6 and the small diameter section 12 are relative, and the large diameter section 6 has a thickness difference compared with the small diameter section 12. The inner diameter of the small diameter section 12 is designed to be adapted to the largest type of the in vivo leading-out drainage tube 1, and the inner diameter of the large diameter section 6 is larger than the outer diameter of the largest type of the in vivo leading-out drainage tube 1. Therefore, the drainage tube 1 can be inserted into the large-diameter section no matter what type of the in-vivo drainage tube, an annular fit clearance exists in the large-diameter section, and the annular air bag 8 can be filled in the annular clearance after being inflated.
In the use of the embodiment, after the intracorporeal drainage tube 1 is inserted from the port of the large diameter section 6, the left hand grips to keep the intracorporeal drainage tube 1 from falling off, and the right hand aligns the tip of the syringe with the air nozzle 9 and presses the handle end of the syringe until the syringe is pressed still. The flat-nose check valve 10 ensures that the annular bladder is only inflated and not self-vented. Therefore, the connector is very convenient to use, can be suitable for sealing connection of drainage tubes 1 led out from bodies with different tube diameters, is simple and reasonable in connector structure, easy to realize, low in cost and suitable for popularization and application. The embodiment also conveniently changes the drainage bag, when needing to change the drainage bag, at first need exhaust annular gasbag 8, owing to adopt be flat mouth check valve 10, insert flat mouth through a thin pole (for example cotton swab) and can deflate, can extract internal drainage tube of drawing forth smoothly after the gassing. Another way of replacing the urinary bag is to directly detach the bag tube 2 from the small diameter section 7.
Example 2: in addition to embodiment 1, the diameter-enlarged section 6 is further modified, for example, as shown in fig. 2-4, an enlarged diameter section 7 is further provided inside the diameter-enlarged section 6, and an annular air bag 8 is fixed in the enlarged diameter section 7. This structural design can reduce the diameter of major diameter section on the whole, does not have the automatic sunken in major diameter section inner wall of inflatable annular gasbag 8 to when drawing drainage tube 1 and inserting in vivo, can not form the interference.
Example 3: on the basis of the embodiments 1 and 2, in the case that the annular airbag is located at the large diameter section or the diameter-expanded section, the present embodiment also has a guide sleeve fixedly sleeved on the port of the large diameter section, and the other end of the guide sleeve is adhered to the surface of the annular airbag. Thus, when the drainage tube 1 is introduced into the body, the tube section does not impact the annular balloon to cause deflection thereof.
Example 4: on the basis of the embodiments 1 and 2, the guide sleeve is fixed to the end of the large diameter section, but in this embodiment, the guide sleeve has elasticity, and the other end of the guide sleeve is adhered to the inner wall of the tapered section 11. The purpose of this embodiment is to provide the internal drainage tube 1 with a guiding sleeve which is elastically contacted and has guiding function, because the inner end of the guiding sleeve is fixed on the inner wall of the conical section, the inner end of the guiding sleeve is pulled, and the guiding sleeve is tightly sleeved on the outer wall of the internal drainage tube 1 due to the elastic action, thereby having higher restraining force and sealing performance.
Based on above embodiments, there can also be part transformation, replacement and simple supplement on the basis of above embodiments, all belong to the technical scheme of the utility model. For example, when the guide sleeve is adopted, the guide sleeve can be led out from the port of the small-diameter section 12 and is sleeved on the outer wall of the small-diameter section in a turnover mode, when the bag pipe 2 is connected, the elastic guide sleeve can be used for sealing the bag pipe 2 and the small-diameter section of the joint, meanwhile, the elastic guide sleeve can be fixedly sleeved between the outer wall of the drainage pipe 1 led out from the body and the annular air bag, and therefore the elastic guide sleeve penetrates through the head of the joint and is connected to the inner cavities of the large-diameter section and the small-diameter section of the joint. And, the connector of this embodiment can also be a constant diameter tube, one end of which is connected with the bag tube 2, and the inner cavity of the other end is sleeved and fixed with the annular air bag 3, and further designs various structures and the like as shown in embodiments 2-4.
