Abstract
Description
Technical Field
[0001] The utility model relates to the field of silicone catheters, in particular to a silicone tube joint structure. Background Art
[0002] Medical silicone tubing is a type of rubber hose used for medical purposes. It is made of silicone rubber and has passed biocompatibility testing. It has little reaction to human tissue. After being implanted into human tissue, it will not cause foreign body reaction and will not cause inflammation to surrounding tissues. It is cold-resistant and high-temperature-resistant, resistant to weak acids and alkalis, harmless, non-toxic and odorless, has good elasticity, is resistant to kinking and deformation, is soft and permanently does not deform. It is suitable for food medical machinery, ventilators, medical diversion, biopharmaceuticals, medical research, medical analytical instruments, hemostatic instruments, biological research institutes, chemical laboratories and other fields.
[0003] Commonly used silicone tubes are generally standardized and custom-made, with both ends connected for ease of use. However, in special circumstances, such as when a catheter needs to be extended or the diameter needs to be changed, two or more silicone tubes must be connected. Currently, this connection typically uses a short hollow tube with a larger inner diameter, through which the two silicone tubes are connected. While this connection method is quick, it has limited stability and is not suitable for long-term continuous operation or connecting silicone tubes of different diameters. This presents a problem.

It should be noted that in the description of this invention, the terms "left," "right," "front," "back," "inside," "outside," and the like, indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of this invention and simplify the description.

[0023] like Figure 1 As shown, the utility model provides a silicone tube joint structure, including a joint valve 3 and two pipe joints, wherein the pipe joints include a male head 2 and a female head 1.
[0024] like Figure 2 As shown, the female connector 1 is divided into a fixed section 11 and a connecting section 12. The inner diameter of the fixed section 11 gradually increases toward the connecting section 12. The inner diameter of the connecting end 12 is constant and has an internal thread. The sub-connector 2 is divided into a second fixed section 21, a second connecting section 22, and a connecting cap 23. The outer diameter of the second fixed section 21 gradually increases toward the second connecting section 22. The outer diameter of the second connecting section 22 is constant and has an external thread. The internal thread of the female connector 12 and the external thread of the sub-connector second connecting section 22 are mutually compatible.
[0025] like Figure 3 、 4 As shown, first put the female head 1 on the silicone tube, then insert the sub-head 2 into the silicone tube, and then thread the connecting section 11 of the female head 1 and the second connecting section 21 of the sub-head 2, clamp the silicone tube 4 between the fixed section 11 and the second fixed section 21, and connect the two ends of the joint valve 3 to the connecting caps 23 of the two pipe joints respectively, thereby connecting the two sections of silicone tube 4.
[0026] As a preferred embodiment, the minimum inner diameter of the female head fixing section 11 is slightly larger than the outer diameter of the silicone tube 4, ensuring that the female head 1 can be sleeved on the silicone tube 4; the minimum outer diameter of the second fixed section 21 of the sub-head 2 is smaller than the inner diameter of the silicone tube 4, ensuring that the sub-head can be inserted into the silicone tube; the maximum outer diameter of the second fixed section 21 is slightly larger than the inner diameter of the silicone tube, but at the same time needs to be smaller than the inner diameter of the female head connecting section 12, ensuring that the sub-head can be threadedly connected to the female head and can clamp the silicone tube.
[0027] As a preferred embodiment, the inner wall of the connecting cap 23 is provided with an internal thread, and both ends of the joint valve 3 are provided with external threads, and the joint valve 3 is threadedly connected to the connecting caps 23 of the two pipe joints.
[0028] It's important to note that the actual specifications of the connection cap and connector valve are unified, while the female connector's connecting section, fixed section, and the male connector's second connecting section and second fixed section can be produced in multiple specifications. When connecting silicone tubing of different diameters, two different-sized pipe connectors can be used.
[0029] As a preferred embodiment, a silicone gasket 5 is provided in the connection cap 23 to improve the sealing of the valve connection and avoid leakage.
[0030] As a preferred embodiment, the connector valve 3 includes a stop valve or a duckbill valve to help the silicone tube stop flow and prevent backflow.
[0031] As a preferred embodiment, the joint valve 3 and the two pipe joints are all made of PC material. PC material has high transparency, high strength as a joint, and good flame retardancy and high temperature resistance.
[0032] The utility model can be connected to the pipe conveniently and quickly, and the silicone tube can be stably used for a long time after being connected, without leakage or falling off, and has good connection stability.
[0033] Furthermore, the specific steps of using this structure are as follows:
[0034] Select appropriate pipe joints according to the two silicone tubes, disassemble the female and male connectors of the pipe joints, first fix the two male connectors to the joint valves, then put the two female connectors on the two silicone tubes respectively, and then insert the second fixed sections of the two male connectors into the two silicone tubes. Finally, pull back the female connector and rotate the female connector to make the female connector and the male connector threadedly connected. The fixed section of the female connector and the second fixed section of the male connector will clamp the silicone tube, and the connection of the two silicone tubes is completed.
[0035] Any matters not described in detail in this utility model are well-known technologies to those skilled in the art. Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not limiting. Although this utility model has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of this utility model can be modified or replaced with equivalents without departing from the purpose and scope of the technical solutions of this utility model, and all such modifications should be included in the scope of the claims of this utility model.
