Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a medical expansion joint. Background Art
[0002] Medical connectors are the most common clinical consumables, and are often used in conjunction with drainage tubes, drainage bags, etc. There are many types of medical connectors currently in use, and appropriate connectors can be selected based on different functions and drainage requirements.
[0003] The most common method is to use drainage tubes in conjunction with connecting joints. The joints are pagoda-shaped and spiral-shaped. In actual use, the diameters of drainage tubes come in different specifications, and different specifications are suitable for different drainage methods and drainage sites. For example, abdominal, bile duct and pancreatic drainage all use drainage tubes of different calibers, while the drainage bags introduced by the unit have the same specifications, resulting in the drainage tubes and drainage bags or the drainage tubes being unable to be smoothly connected. Even if some are connected, the connection will be loose, resulting in dislocation or leakage. Improper connecting tubes are prone to drainage fluid overflow when replacing the drainage bag, and clinical fixation with tape cannot achieve the expected effect. Summary of the invention
[0004] The utility model aims to design a medical telescopic joint, through which drainage tubes with different calibers can be smoothly butted against each other to ensure butt matching and tight connection.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0006] A medical telescopic joint comprises a large joint which is in a cone shape, has a cavity at the front end and a through hole at the rear end, and a small joint is accommodated in the cavity. The rear of the small joint is connected to a tube body which passes through the through hole.
[0007] Furthermore, the large joint and the small joint are tower-shaped conical joints.
[0008] Furthermore, the inner diameter of the front end of the large joint is larger than the outer diameter of the rear end of the small joint.
[0009] Furthermore, the outer surface of the tube body is provided with an external thread, and the inner surface of the through hole is provided with an internal thread, and the tube body and the through hole cooperate with each other through the threaded relationship to realize spiral motion.
[0010] Furthermore, a rotating part is provided on the pipe body at the rear end of the large joint.
[0011] A drainage bag, a tube body leading out of the drainage bag is installed with the telescopic joint of the present application, the telescopic joint comprises a large joint, the large joint is in a cone shape, a cavity is provided at the front end of the large joint, a through hole is provided at the rear end of the large joint, a small joint is accommodated in the cavity, the small joint is connected to the tube body at the rear, and the tube body passes through the through hole.
[0012] The following beneficial effects can be obtained through the above technical solution:
[0013] The overall structure of the utility model is relatively simple, and can meet the connection between drainage tubes of different calibers. It is particularly suitable for abdominal cavity, bile duct and pancreatic drainage, and can effectively realize the connection between drainage tubes of different calibers. At the same time, the utility model also provides a drainage bag with an expansion joint installed. The drainage bag can be smoothly docked with its drainage tube in abdominal cavity, bile duct and pancreatic drainage, and the docking is firm without the problem of dislocation or leakage.

[0020] The utility model is further described below in conjunction with the accompanying drawings:
[0021] like Figure 1-3 As shown, a medical telescopic joint includes a large joint 1, which is a tower-shaped cone joint. A cavity 6 is provided at the front end of the large joint, and a through hole 7 is provided at the rear end of the large joint. The inner surface of the through hole is provided with an internal thread. A small joint 2 is accommodated in the cavity. The small joint 2 is connected to a tube body 4 at the rear, and an external thread 3 is provided on the outer surface of the tube body 4. The tube body 4 is screwed into the thread structure of the through hole through a thread structure. A rotating part 5 is provided on the tube body at the rear end of the large joint.
[0022] During specific use, when facing drainage tubes of different calibers, the tube body at the rear end of the large joint of the utility model is connected to the drainage tube that matches the same caliber. The diameter of the other drainage tube is relatively large, so it is inserted into the large joint; if the diameter of the other drainage tube is relatively small, the rotating part 5 can be rotated so that the tube body pushes the small joint 2 out of the cavity 6, and the drainage tube with a relatively small diameter is inserted into the small joint.
[0023] Based on the telescopic joint of the present application, a drainage bag ( Figure 4As shown), the drainage bag adopts a conventional structural shape, the difference is that the telescopic joint of the present application is directly installed on the hose leading out of the drainage bag, so the telescopic joint carried by the drainage bag can be smoothly docked with drainage tubes of different calibers and models. For example: when draining liquid from ascites, the thickness of the drainage tube is determined according to the purpose of drainage, because different drainage tubes have different thicknesses. If it is a conventional drainage bag, it cannot meet the docking of drainage tubes of different thicknesses. The drainage bag of the utility model adopts a telescopic joint, and a thinner drainage tube can be docked with a small joint, and a thicker drainage tube can be docked with a large joint.
[0024] The above are all preferred implementations of the present invention. For ordinary technicians in this technical field, without departing from the principle of the present invention, various equivalent modifications to the present invention belong to the protection scope of the claims attached to this application.
